[(2) deleted] [Regulation 5 amended: Gazette 31 Mar 2006 p. 1329‑30 and 1338; 26 Jun 2007 p. 3022.] 6. Restricted application of regulations The application of these regulations is limited to — (a) access agreements in operation on 1 July 2007; and (b) the parties to those agreements; and (c) matters relating to the provision of access services under those agreements, and references in these regulations to an access agreement, a corporation or a user are to be construed accordingly. [Regulation 6 inserted: Gazette 26 Jun 2007 p. 3022-3.] Part 2 — Access 7. Access procedure The procedure to be followed under this Part is illustrated by the flow chart in Schedule 1. 8. Access application (1) A person who is not an existing user and who wants a corporation to provide it with one or more access services must make an access application in accordance with this regulation. (2) A person who is an existing user and who wants a corporation to provide it with one or more access services (including additional capacity) in addition to those which the user has access already must make an access application in accordance with this regulation. [(3) deleted] (4) An access application must contain the information listed in Part A of Schedule 2 and may specify that the applicant wishes the corporation to make a preliminary assessment of the access application. (5) The corporation must give the applicant a written response within 20 business days after receiving the access application. (6) A response in respect of an access application must include the following information — (a) the information listed in Part B of Schedule 2; (b) the period within which the corporation is able to make a preliminary assessment of the access application; and (c) whether the corporation is able to make an access offer to the applicant within 65 business days of receiving the access application, and, if not, an alternative period that is reasonable for making the access offer. (7) The information provided under subregulation (6)(a) is indicative and is not binding on the corporation. [Regulation 8 amended: Gazette 31 Dec 2004 p. 7139; 31 Mar 2006 p. 1330 and 1338-9.] 9. Provision and use of information in respect of an access application (1) A corporation may request further information from an applicant. (2) A request for further information under subregulation (1) must be in writing. (3) A corporation may only request further information under subregulation (1) if the information requested is reasonably necessary in order to — (a) process the access application; (b) prepare a response; (c) carry out a preliminary assessment; or (d) make an access offer to provide access services, as the case requires. (4) If — (a) a corporation makes a request under subregulation (1) in relation to an access application; and (b) the person to which the request has been made has not provided all the information requested within 15 business days of the corporation making the request or such longer time as the corporation and the person agree, then the access application loses its priority for the purposes of regulation 13 and lapses. (5) If an access application loses its priority under subregulation (4) and the person to which the request has been made subsequently provides all the information requested, then the priority of the access application for the purposes of regulation 13 is to be determined as if the access application had been received on the date on which that information is received by the corporation. (6) An applicant, in making an access application and providing information under this Part must — (a) act in good faith; and (b) use reasonable endeavours to ensure that the access application and the information concerned are accurate and complete. (7) If an applicant becomes aware of any material alteration to any information contained in or relevant to the access application, then the applicant must promptly notify the corporation in writing of that alteration. (8) If a corporation receives a notice under subregulation (7) or otherwise becomes aware of any material alteration to any information contained in or relevant to an access application, then the corporation may, by written notice to the applicant — (a) extend the period within which the corporation must give the response under regulation 8(5) or carry out the preliminary assessment and give the report under regulation 10 or make the access offer under regulation 11(1) in respect of the access application (as the case requires), to such longer period as the corporation reasonably requires in order to do so; or (b) where the material alteration to information is such as to, in the reasonable opinion of the corporation, materially alter the access services requested by the access application, the corporation may reject the access application. [Regulation 9 amended: Gazette 31 Mar 2006 p. 1338-9.] 10. Preliminary assessment (1) If an access application specifies that the applicant wishes the corporation to make a preliminary assessment of the access application, then the corporation must make that preliminary assessment and give the applicant a report of that preliminary assessment within the period for making the preliminary assessment specified in the response in respect of the access application. (2) A report under subregulation (1) is indicative and is not binding on the corporation. [Regulation 10 amended: Gazette 31 Mar 2006 p. 1339‑40.] 11. Access offer (1) Subject to regulation 13, unless otherwise agreed by the applicant and the corporation, the corporation must make an access offer to provide to the applicant the access services requested in an access application — (a) within 65 business days of the corporation receiving the access application; or (b) if a longer period for making the access offer is specified in the corporation's response to the applicant under regulation 8(5), then within that longer period. (2) If the corporation makes a request for information under regulation 9(1) to an applicant, then the period referred to in subregulation (1) ceases to run until the information requested by the corporation is received by the corporation. (3) An access offer must — [(a) deleted] (b) subject to paragraphs (e) and (f), be for the access services requested in the access application in response to which it is made and be consistent with any technical parameters specified in that access application; (c) be in writing and contain the proposed terms and conditions on which the corporation will provide the access services, including terms and conditions of the kind set out in Schedule 3; (d) specify how the charges for the access services requested in the access application are to be calculated and how the fees used in calculating those charges are to be determined; (e) be consistent with the Act, these regulations and the Technical Code; and (f) to the extent that it contains terms and conditions, or sets fees and charges other than those in the fee schedule, be fair and reasonable and consistent with good electricity industry practice. (4) If the corporation believes that the requirements of the person making an access application would be met by the corporation providing one or more different access services (called the alternative services) to those requested in the access application, then the corporation may, in addition, make an offer in accordance with subregulation (3)(a), (c), (d), (e) and (f) in relation to those alternative services. (5) To avoid doubt — (a) subject to subregulation (3)(b), an access offer may contain terms and conditions which differ from those contained in the relevant access application; (b) an access agreement may contain terms and conditions which differ from those contained in the relevant access offer; and (c) subject to regulation 46, an access offer and an access agreement may contain terms and conditions (including terms and conditions related to fees and charges) which differ from those contained in another access offer or access agreement for any reason, including — (i) to reflect the provisions of these regulations; (ii) the quantities in which the relevant access services are to be supplied or are supplied; (iii) because of the different nature of the plant or equipment required to provide the relevant access services; (iv) the geographical and electrical location of the relevant connections; (v) the periods for which the relevant access services are supplied; (vi) the electricity transmission capacity required to provide the relevant access services; (vii) the characteristics of the relevant load or generation; and (viii) the performance characteristics at which the relevant access services are provided. (6) If — (a) a corporation makes an access offer to an applicant; and (b) the corporation and the applicant have not entered into an access agreement in relation to the access services which are the subject of the access offer within the relevant period determined in accordance with subregulation (7), then the access offer expires and the access application loses its priority for the purposes of regulation 13 and lapses. (7) The relevant period for the purposes of subregulation (6) is a period of 20 business days (or such longer period as the corporation may agree with the applicant) following the day on which the access offer is made. (8) The provision of access services by a corporation under an access agreement is subject to the following conditions precedent — (a) the corporation or the user gaining environmental and planning approvals for any necessary augmentation to the electricity transmission network or the design, construction, installation and commissioning of any exempt connection contemplated by the access agreement; (b) the corporation gaining the approval of the Minister under section 68 of the Electricity Corporations Act 2005, if required; and (c) the entry into of a connection agreement with the corporation by such of the controllers as the corporation requires in relation to the connection (in form and substance satisfactory to the corporation, acting reasonably), if the person with which the corporation enters into the access agreement is not the controller or is not the only controller in respect of a connection which is the subject of the access agreement. (9) If — (a) a corporation makes an access offer; and (b) one or more of the connections to which the access offer relates is an exempt connection, then the access offer must — (c) inform the applicant that the applicant may choose not to have the connection services at the exempt connection provided by the corporation; and (d) contain the proposed terms and conditions on which the corporation will — (i) if the applicant chooses not to have the corporation provide the connection services at the exempt connection, augment the electricity transmission network to the extent necessary to permit the transfer of electricity between the electricity transmission network and the exempt connection; or (ii) if the applicant chooses to have the corporation provide the connection services at the exempt connection, augment the electricity transmission network and provide the connection services at the exempt connection, including terms and conditions relating to the design, construction, installation, commissioning and testing of the augmentation or the exempt connection, as the case requires. [Regulation 11 amended: Gazette 24 Jun 2005 p. 2753; 31 Mar 2006 p. 1331 and 1338-41.] 12. Capital contributions (1) For the purposes of this regulation, an augmentation is commercially viable if — (a) in the case of the Electricity Networks Corporation, in the corporation's reasonable opinion — (i) it will recover within a reasonable time the costs, the capital investment and a reasonable rate of return on the capital investment in respect of the augmentation as contemplated by clause 5 of Schedule 5 to the Act (as in force before the repeal of that Schedule by the Electricity Transmission and Distribution Systems (Repeal and Related Provisions) Regulations 2007), and not increase the charges payable by existing users; and (ii) it has sufficient allocated capital funds to undertake the augmentation, having regard to sections 127 and 128 of the Electricity Corporations Act 2005; and (b) in the case of the Regional Power Corporation, in the corporation's reasonable opinion — (i) it will recover within a reasonable time the costs, the capital investment and a reasonable rate of return on the capital investment in respect of the augmentation as contemplated by clause 5 of Schedule 5 to the Act (as in force before the repeal of that Schedule by the Electricity Transmission and Distribution Systems (Repeal and Related Provisions) Regulations 2007), and not increase the charges payable by existing users; and (ii) the division of the corporation responsible for operating its electricity transmission network has sufficient allocated capital funds to undertake the augmentation, having regard to sections 127 and 128 of the Electricity Corporations Act 2005. (2) The reasonable rate of return on the capital investment associated with a proposed augmentation contemplated by subregulation (4)(c) or subregulation (5)(b) is to be determined by a corporation taking into account — (a) the corporation's cost of capital and its components; (b) the potential future use of the augmentation by existing and potential users; (c) the financial viability of the applicant and the applicant's business; (d) the impact of the capital investment upon the performance targets and other measures of the corporation's performance as set out in any applicable statement of corporate intent under the Act. (3) The reasonable time within which the costs, the capital investment and the reasonable rate of return in respect of a proposed augmentation contemplated by subregulation (4)(c) or subregulation (5)(b) must be recovered is to be determined by a corporation taking into account — (a) the anticipated commercial life of the augmentation; and (b) the purpose for which the applicant requires the electricity transmission capacity the subject of the relevant access offer, but in any event cannot exceed 15 years. (4) If — (a) a corporation and a user enter into an access agreement; (b) the services to be provided under the access agreement include connection services using a connection that is not an exempt connection; (c) the corporation is not able to reliably provide those connection services without augmenting that connection; and (d) the augmentation concerned is not commercially viable without any capital contribution, then the user must make a capital contribution towards the augmentation in accordance with this regulation. (5) If — (a) a corporation and a user enter into an access agreement; (b) the corporation is not able to reliably provide the access services which are the subject of the access agreement without augmenting the electricity transmission network to either transport electricity on the network or to link the network to an exempt connection; and (c) the augmentation concerned is not commercially viable without any capital contribution, then the user must make a capital contribution towards the augmentation in accordance with this regulation. (6) If subregulation (4) or subregulation (5) requires a user to make a capital contribution, then — (a) the amount of the capital contribution is equal to the amount that would be required to make the augmentation commercially viable; and (b) the capital contribution must be paid to the corporation in the manner and at the time set out in the access agreement. (7) A proposed augmentation satisfies paragraph (a) of the commercial viability test set out in subregulation (1) if — (a) the discounted present value of the future cash flows anticipated in respect of the augmentation over the reasonable time in respect of the augmentation is determined in accordance with subregulation (3), using a real discount rate equal to the reasonable rate of return in respect of the augmentation determined in accordance with subregulation (2); and (b) that discounted present value is positive. (8) If — (a) a corporation and a user enter into an access agreement; (b) the services to be provided under the access agreement include access services in respect of a connection that is not an exempt connection; and (c) the corporation is obliged under an existing agreement to repay an amount of money to a person if it provides those services, then the user must pay the corporation an amount equal to the amount referred to in paragraph (c). (9) If — (a) a corporation makes an access offer; and (b) the access offer contemplates the provision of connection services or ancillary services using an exempt connection, then the corporation may include in the access offer a condition that the user makes a capital contribution in respect of the capital investment associated with designing, constructing, installing and commissioning the connection equipment or with providing those ancillary services (as the case requires) and a rate of return on that investment and, if so, the capital contribution must be taken into account in the determination of fees for providing the connection services or the ancillary services (as the case requires) set out in the access offer. [Regulation 12 inserted: Gazette 1 Jul 1997 p. 3251‑2; amended: Gazette 28 Dec 2001 p. 6718; 31 Mar 2006 p. 1331‑2 and 1338-41; 26 Jun 2007 p. 3023.] 13. First come first served (1) If — (a) a corporation has received 2 or more access applications; and (b) the corporation believes there is not sufficient spare capacity to provide the access services the subject of all of those access applications or that it does not have sufficient resources (including personnel) to process all of those access applications at the same time, then the corporation must process those access applications and make access offers in an order which reflects the priority of those access applications as determined in accordance with these regulations. (2) An access application (in this subregulation called the first access application) received by a corporation has priority over all later access applications received by the corporation unless the first access application loses its priority in accordance with these regulations. (3) The applicant making an access application may withdraw that access application by written notice given to the corporation and if an applicant does so, then the access application loses its priority and lapses. (4) If a corporation rejects an access application under these regulations, then the access application loses its priority for the purposes of this regulation and lapses. (5) If an access offer is rejected prior to the end of the relevant period determined in accordance with regulation 11(7), then the access application in response to which the access offer was made loses its priority and lapses. (6) Nothing in this regulation prevents a corporation from processing more than one application at the same time. (7) Notwithstanding any other provision of these regulations, if an access application lapses, then a corporation is not required to take any further action in relation to the access application (including making a preliminary assessment of the access application and giving a report under regulation 10 or making an access offer under regulation 11 in relation to the access application). [Regulation 13 amended: Gazette 31 Mar 2006 p. 1338-40.] 14. Confidentiality (1) In this regulation — access information, in respect of a person, means all information contained in the following documents — (a) an access application made by that person; (b) the response by a corporation to the access application made by that person; (c) the report of a preliminary assessment under regulation 10(1) of that access application; (d) the access offer made to that person in respect of the access services which are the subject of the access application; (e) any information provided by that person in response to a request under regulation 9 in relation to the access application; (f) in respect of a person which takes electricity from the electricity transmission network, the quantity taken; and (g) in respect of a person which transfers electricity to the electricity transmission network, the quantity transferred.

Balancing (1) A user must use reasonable endeavours to ensure that the energy entry amount for the group of connections in respect of each of its access agreements for each half hour is equal to the energy exit amount for the group of connections for that half hour. (2) For the purposes of subregulation (3), the revised net amount for the group of connections in respect of a user's access agreement for a half hour is an amount equal to the energy entry amount for the group of connections for the half hour minus the energy exit amount for the group of connections for the half hour, except where — (a) that amount is positive and is equal to or less than the permitted tolerance for the group of connections; or (b) that amount is negative and is greater than or equal to zero minus the permitted tolerance, in which case, the revised net amount for the group of connections is equal to zero. (3) The half hourly out of balance charge in respect of an access agreement for a half hour is determined by applying the following formula: where — HOBC (in $) is the half hourly out of balance charge in respect of the access agreement for the half hour; RNA (in kWh) — (a) if the revised net amount for the group of connections in respect of the access agreement for the half hour is positive, then is equal to that revised net amount minus the permitted tolerance for the group of connections; or (b) if the revised net amount for the group of connections in respect of the access agreement for the half hour is negative, then is equal to that revised net amount plus the permitted tolerance for the group of connections; HOBF (in ¢/kWh) is — (a) if RNA is negative, then the half hourly out of balance (sell) fee set out in the fee schedule for the financial year in which the half hour falls applicable to the half hour; or (b) if RNA is positive, then the half hourly out of balance (buy) fee set out in the fee schedule for the financial year in which the half hour falls applicable to the half hour. (4) If the sum of the half hourly out of balance charges for the half hours in a month is negative, then an amount equal to ‑1 multiplied by that sum is payable by the user to the corporation, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation. (5) If the sum for the half hourly out of balance charges for the half hours in a month is positive, then an amount equal to that sum is payable by the corporation to the user, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation. (6) For the purposes of subregulation (7), the adjusted net amount for the group of connections in respect of a user's access agreement for a half hour is an amount equal to the energy entry amount for the group of connections for the half hour minus the energy exit amount for the group of connections for the half hour, except where — (a) the result is positive and is greater than the permitted tolerance for the group of connections, in which case the adjusted net amount for the group of connections is equal to that permitted tolerance; or (b) the result is negative and is less than zero minus that permitted tolerance, in which case the adjusted net amount for the group of connections is equal to zero minus that permitted tolerance. (7) The out of balance charge in respect of an access agreement for a month is determined by applying the following formula: where — OBC (in $) is the out of balance charge in respect of the access agreement for the month; ANA (in kWh) is the sum of the adjusted net amounts for the group of connections in respect of the access agreement for all of the half hours falling within the month; OBF (in ¢/kWh) is determined as follows — (a) if ANA is negative, then OBF is the out of balance (sell) fee set out in the fee schedule for the financial year in which the month falls; (b) if ANA is positive, then OBF is the out of balance (buy) fee set out in the fee schedule for the financial year in which the month falls. (8) If the out of balance charge for a month is negative, then the amount equal to ‑1 multiplied by that out of balance charge is payable by the user to the corporation, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation. (9) If the out of balance charge for a month is positive, then an amount equal to that out of balance charge is payable by the corporation to the user, except if the user is the Electricity Generation and Retail Corporation or the Regional Power Corporation.

Excess network usage charge (1) In this subregulation and subregulation (2) — (a) the excess amount in respect of an entry point for a half hour is equal to — (i) the average aggregate rate (in kW) at which the generating units connected at the entry point transferred electricity to the electricity transmission network during that half hour; minus (ii) the aggregate of the declared sent‑out capacity figures (in kW) for those generating units, but if the result of this calculation is negative, then the excess amount in respect of the entry point for the half hour is zero; (b) if the excess amount in respect of an entry point for a half hour is more than zero, then an excess period in respect of the entry point commences at the start of that half hour, except if that half hour already falls within an excess period in respect of the entry point; and (c) each excess period in respect of an entry point includes 336 half hours. (2) If an excess period in respect of a user's entry point commences during a month, then the excess network usage charge payable by the user in respect of the entry point for the month is determined by applying the following formula: where — ENUC (in $) is the excess network usage charge in respect of the entry point for the month; Ei (in kW) is the highest excess amount for any of the half hours which fall within excess periodi; USF (in $/kW) is the use of system fee in respect of the entry point determined in accordance with the user's access agreement; EF (a rate) is the excess network usage factor set out in the fee schedule for the financial year in which the month falls; the variable "i" represents an excess period in respect of the entry point which commences during the month; the variable "n" represents the number of excess periods in respect of the entry point which commence during the month. (3) In this subregulation and subregulation (4) — (a) the excess rate in respect of an exit point for a half hour is equal to — (i) the average rate (in kW) at which electricity is transferred from the electricity transmission network at the exit point during that half hour; minus (ii) the contract maximum demand for the exit point, but, if the result of this calculation is negative, then the excess rate in respect of the exit point for the half hour is zero; (b) if the excess rate in respect of an exit point for a half hour is more than zero, then an excess demand period in respect of the exit point commences at the start of that half hour, except if that half hour already falls within an excess demand period in respect of the exit point; and (c) each excess demand period in respect of an exit point includes 336 half hours. (4) If an excess demand period in respect of a user's exit point commences during a month, then the excess network usage charge payable by the user in respect of the exit point for the month is determined by applying the following formula: where — ENUC (in $) is the excess network usage charge in respect of the exit point for the month; Ei (in kW) is the highest excess rate for any of the half hours which fall within excess demand periodi; USF (in $/kW) is the use of system fee in respect of the exit point determined in accordance with the user's access agreement; CSF (in $/kW) is the common service fee determined in accordance with the user's access agreement; EF (a rate) is the excess network usage factor set out in the fee schedule for the financial year in which the month falls; the variable "i" represents an excess demand period in respect of the exit point which commences during the month; the variable "n" represents the number of excess demand periods in respect of the exit point which commence during the month.

Safety and security of electricity transmission network (1) If a corporation is satisfied that it is necessary so to do for reasons of public safety or the security of its electricity transmission network, then the corporation may direct a user to do any one or more of the following — (a) establish or remove a connection; (b) disconnect a connection; (c) to switch off a generator; (d) to call plant or equipment into service; (e) to take plant or equipment out of service; (f) to commence operation of any plant or equipment or maintain, increase or reduce generation or absorption of active or reactive power output by any plant or equipment; (g) to shut down or vary operation of any plant or equipment; (h) to shed or restore load; or (i) to do any other act or thing necessary to be done. (2) A direction under subregulation (1) must specify the period within which the direction must be complied with and for how long the direction must be complied with. (3) A direction under subregulation (1) must be recorded by the corporation. (4) If a person (in this regulation called the first person) is directed to do something under subregulation (1) but does not comply with the direction, then the corporation may authorise an employee of the corporation or another person to carry out that direction and the first person must do all such things as the first person is requested by the authorised person to do in order to assist the authorised person to carry out that direction. (5) Regulations 25 and 29 and this regulation do not limit any power or right conferred by any other law or by agreement on a corporation. [Regulation 30 amended: Gazette 31 Mar 2006 p. 1334 and 1338‑40.] 31. Operation, maintenance and extension planning (1) The purpose of this regulation is to ensure that, so far as possible, outages of plant or equipment forming part of, or connected to, a corporation's electricity transmission network are coordinated. (2) On or before 30 September each year, each user must provide to the corporation — (a) a maintenance schedule in respect of the plant and equipment connected at each of its connections for the following financial year; and (b) a non‑binding indicative planned maintenance plan in respect of the plant and equipment connected at each of its connections for each of the 2 financial years following the financial year to which the maintenance schedule provided under paragraph (a) relates. (3) A user must provide the corporation with any information that the corporation reasonably requests concerning maintenance of plant and equipment connected at the user's connections. (4) A user must ensure that a maintenance schedule provided by the user under subregulation (2) is complied with, unless otherwise agreed with the corporation. (5) A maintenance schedule or a maintenance plan must — (a) specify the dates and duration of planned outages for the relevant plant or equipment which may have an impact on the electricity transmission network; (b) specify the work planned to be carried out during each such outage; (c) be in writing in substantially the form requested by the corporation; and (d) be consistent with good electricity industry practice. (6) If a user becomes aware that a maintenance plan provided by the user under subregulation (2) in respect of one of its connections will not be complied with, then the user must promptly notify the corporation. [Regulation 31 amended: Gazette 31 Mar 2006 p. 1335 and 1339.] 32. Information required to prepare annual reports (1) Each user must, on or before 31 July in each year, provide a corporation with such electricity generation and load forecast information in relation to each of its connections as is reasonably required by the corporation. (2) Each user must use reasonable endeavours to provide accurate and complete information under subregulation (1). [Regulation 32 amended: Gazette 31 Mar 2006 p. 1338-9; 26 Jun 2007 p. 3024.] 33. Augmentation of the electricity transmission network (1) Without limiting a corporation's obligations under the Act, any proposal to augment its electricity transmission network must be consistent with the network planning criteria to the extent that the corporation reasonably believes the network planning criteria are applicable in the circumstances. (2) Subject to regulation 14, if a corporation believes that it is necessary or desirable to augment its electricity transmission network, then the corporation must consult with any person who is — (a) a user or who has made an access application; and (b) in the corporation's opinion, likely to be materially affected by the proposed augmentation. [Regulation 33 amended: Gazette 31 Mar 2006 p. 1335 and 1338‑41.] Part 6 — Access terms 34. Reasonable endeavours Notwithstanding the terms of any access agreement, an obligation on a corporation to provide access services or to ensure service quality parameters in relation to its electricity transmission network is to be read and construed as an obligation to use all reasonable endeavours to provide those services or ensure those parameters. [Regulation 34 amended: Gazette 31 Mar 2006 p. 1335 and 1338.] 35. Force majeure and interruption (1) A force majeure event in respect of a party to an access agreement or a person to which these regulations apply means any event outside the party's control, including — (a) any act of God, lightning, earthquake, storm, fire, flood, subsidence, land slide, mud slide, wash‑out, explosion or natural disaster; (b) any insurrection, revolution or civil disorder, act of public enemies, malicious damage, sabotage, vandalism, war (whether declared or undeclared) or a military operation, blockade or riot; (c) any determination, award or order of any court or tribunal, or any regulatory authority or the award of any arbitrator; (d) any act or omission of government or any government or regulatory department, body, instrumentality, ministry, agency, fire brigade or any other authority other than the corporation or the user (including restraint, expropriation, prohibition, intervention, direction or embargo); (e) any inability or delay in obtaining any governmental, quasi‑governmental or regulatory approval, consent, permit, licence or authority; (f) any industrial disputes of any kind, strike, lock‑out, ban, limitation or other industrial disturbances; (g) any significant plant or equipment failure which could not have been avoided by the exercise of good electricity industry practice; (h) where the person is party to an access agreement, any act or omission of any person with facilities connected to the electricity transmission network which frustrates the party's ability to perform its obligations under the access agreement; (i) any application of any law of the Commonwealth, any Commonwealth authority, the State, any State authority or any local government. (2) If a user, a corporation or a person who makes an access application (called the affected person) is unable wholly or in part to perform on time and as required any obligation under the access agreement or these regulations (other than an obligation to pay money) because of the occurrence of a force majeure event, then, subject to this regulation, that obligation (called the affected obligation) is suspended to the extent that and for so long as the affected person's ability to perform the affected obligation is affected by that force majeure event. (3) Without limiting subregulation (2), a corporation's obligation to transfer electricity to or from a connection by means of the electricity transmission network or provide an access service is suspended during any period that the transfer of electricity to or from that connection or the provision of the access service in respect of that connection is interrupted or curtailed under regulation 25 or regulation 29 to the extent of the interruption or curtailment. (4) Subject to subregulations (5), (6) and (7), if a force majeure event occurs, then the affected person must — (a) notify any person who in the affected person's reasonable opinion is likely to be adversely affected by the suspension of the affected obligations; and (b) use reasonable endeavours (including incurring any reasonable expenditure of funds and rescheduling man power and resources) to mitigate the consequences and minimise any resulting delay in the performance of the affected obligation. (5) If an affected person fails to comply with subregulation (4)(b), then the only consequence of that failure is that the period of suspension of the affected obligation is reduced by the period of any delay in the performance of the affected obligation attributable to that failure. (6) The settlement of a labour dispute which constitutes a force majeure event is a matter which is within the absolute discretion of the affected person. (7) An affected person is not obliged to incur any expenditure in complying with subregulation (4)(b) if the force majeure event is constituted by a breach of, or failure to comply with, the access agreement by another party to the access agreement or these regulations by another person to which these regulations apply. [Regulation 35 amended: Gazette 31 Mar 2006 p. 1339-41.] 36. Effect of access to capacity By executing or complying with its obligations under an access agreement or making any capital contribution under an access agreement, a user does not acquire any right, title or interest in or to the electricity transmission network. 37. Minimum term and renewal (1) The term of an access agreement is such term as the parties agree and set out in the access agreement, but in any event must not be less than 3 months. (2) Subject to the terms of the access agreement, an access agreement with an original term of one year or more may be renewed by the user for a further term equal to the original term — (a) if the original term is less than or equal to 3 years, then by written notice to the corporation received at least 3 months prior to expiration of the original term; or (b) if the original term is more than 3 years, then by written notice to the corporation received at least 6 months prior to expiration of the original term, without the requirement for a further access application. (3) In assessing whether or not there is a spare capacity, it must be assumed that an access agreement which may be renewed in accordance with subregulation (2) will be renewed in accordance with that regulation until the time for exercising the option to renew contemplated by that regulation has expired without that option being exercised. [Regulation 37 amended: Gazette 31 Mar 2006 p. 1339‑40.] 38. Contract maximum demand and declared sent‑out capacity (1) If the user's access agreement in respect of a connection sets out a contract maximum demand for that connection, then the user must use reasonable endeavours to ensure that the user's actual demand at that connection does not exceed that contract maximum demand. (2) The declared sent‑out capacity of a generating unit which is not an embedded generating unit is the capacity of the generating unit to generate and transfer electricity to the electricity transmission network, taking into account any electricity used at the connection. (3) The declared sent‑out capacity of an embedded generating unit is the capacity of the generating unit to generate and transfer electricity to the electricity transmission network, taking into account any electricity used at the connection or supplied to persons otherwise than through the electricity transmission network. (4) Subject to subregulation (10), the declared sent‑out capacity for a generating unit is the figure published by a corporation in respect of the generating unit from time to time. (5) A corporation must publish the declared sent‑out capacity for generating units as at 1 April 2006 on or before 1 May 2006. (6) Subject to the terms of the relevant access agreement, if a user wishes to change the declared sent‑out capacity of a generating unit connected at a connection of the user for a financial year, then the user must notify the corporation in writing of the new declared sent‑out capacity of the generating unit not less than 30 business days prior to the start of the financial year. (7) If a user does not give a notice in accordance with subregulation (6) in respect of a generating unit connected at one of its entry points prior to the start of a financial year, then, subject to subregulation (10), the declared sent‑out capacity of the generating unit for that financial year is the same as it was for the preceding financial year. (8) Subject to subregulation (10), the declared sent‑out capacity for a financial year for a generating unit connected at a connection commissioned during the financial year is the figure agreed between the corporation and the user in respect of the entry point prior to electricity first being transferred between the electricity transmission network and the connection. (9) The declared sent‑out capacity of a generating unit for a financial year set out in a notice given under subregulation (6) must not exceed the declared sent‑out capacity of the generating unit for the immediately preceding financial year without the prior written agreement of the corporation. (10) A corporation and a user may vary the declared sent‑out capacity of a generating unit connected at a connection of the user for a financial year by agreement. [Regulation 38 amended: Gazette 31 Mar 2006 p. 1335 and 1338‑40.] 39. Commencement date (1) An access agreement commences on the day it is entered into by the corporation and the user and the term of the access agreement runs from that day. (2) An access agreement may provide for a later day on which the provision of access services is to commence, and, if it does so, then the corporation is under no obligation to provide access services under that access agreement until that later day. [Regulation 39 amended: Gazette 31 Mar 2006 p. 1339‑40.] Part 7 — Enforcement, liability and insurance 40. Enforcement (1) If a user fails to observe or perform any of its obligations under an access agreement (in this regulation called a default), then a corporation may — (a) notify the user of the default and require the user to remedy the default; (b) if the default is a default in the payment of any amount and has not been remedied by the end of the 3rd business day after the notice was given, then disconnect the user's connections from the electricity transmission network whilst that default is continuing; (c) if the default is any other type of default and at the end of the 5th business day after the notice was given — (i) the default has not been remedied; or (ii) the user has not to the reasonable satisfaction of the corporation commenced to remedy the default or has commenced to remedy the default but is not diligently proceeding to remedy the default, then disconnect the user's connections from the electricity transmission network whilst that default is continuing; and (d) if the default has not been remedied at the end of the 20th business day after the notice was given, then treat the default as a repudiation of the access agreement and terminate the access agreement. (2) The rights of a corporation under this regulation (except the periods of notice) are in addition to and are not to limit any other rights which the corporation has under an access agreement or any other rights or remedies which it has under any other written law, at law, in equity or otherwise. (3) Specifically, the imposition by a corporation of a charge under Part 4 or otherwise for the use of any access service other than in accordance with the access agreement does not affect the corporation's rights under this regulation and is not to be taken as any commitment by the corporation to provide any additional access services. (4) Termination of an access agreement under this regulation does not prejudice the rights or remedies accrued to either party at the date of termination. [Regulation 40 amended: Gazette 28 Dec 2001 p. 6719; 31 Mar 2006 p. 1338-41.] 41. Liability, insurance and indemnity (1) In this regulation — direct damage suffered by a person means loss or damage suffered by the person which is not indirect damage; indirect damage suffered by a person, means — (a) any consequential loss, consequential damage or special damages however caused suffered by the person including any — (i) loss of (or loss of anticipated) use, production, revenue, income, profits, business and savings; or (ii) business interruption, whether or not the consequential loss or damage or special damages was foreseeable; (b) in respect of contractual damages, damages which would fall within the second limb of what is known as the rule in Hadley v Baxendale; and (c) any liability of the person to any other person, or any claim, demand, action or proceeding brought against the person by any other person, and the costs and expenses connected with the claim. (2) To the maximum extent permitted by law, the only warranties and terms which apply to the provision of access services by a corporation are those expressly contained in an access agreement, and all warranties and terms (except those expressly set out in an access agreement) implied by law, including implied by the provisions of the Trade Practices Act 1974 of the Commonwealth or any legislation (whether Commonwealth or otherwise) to similar effect, on the part of the corporation, do not apply to the provision of access services by the corporation. (3) If at law, the exclusion of any warranty or term is prohibited, then a corporation's liability in respect of a breach of such warranty or term, is limited to the maximum extent permitted by law. For example, where any law permits a corporation to limit its liability in respect of a breach of an implied warranty or condition to the replacement or resupply of equivalent goods and services, then the corporation's liability will be so limited. (4) A corporation or a user who is negligent, or defaults in respect of its obligations under an access agreement, is liable to the other party (including its directors, servants, consultants, independent contractors and agents) for, and is to indemnify the other party (including its directors, servants, consultants, independent contractors and agents) against, any direct damage caused by, consequent upon or arising out of the negligence or default. (5) A party to an access agreement who is fraudulent in respect of its obligations to the other party under the access agreement, is liable to the other party for, and is to indemnify the other party against, any direct damage or indirect damage caused by, consequent upon or arising out of the fraud. (6) Except as provided in subregulation (5), neither a corporation nor any user is in any circumstances to be liable to the other for indirect damage, however arising. (7) Each user must indemnify a corporation for all liability on the part of the corporation to any customer of the user or any generator of the user (including for direct and indirect damage) which the corporation may suffer because of the provision of or failure to provide access services to the user, except only to the extent that such liability is caused by, is consequent upon or arises out of the negligence of the corporation or the breach by the corporation of any term of the relevant access agreement. (8) Each user must indemnify a corporation for all liability (including direct and indirect damage) which the corporation may suffer to any third party by reason of the default of that user under these regulations or under the access agreement or the negligence of that user. (9) The terms of an access agreement may contain additional provisions relating to liability of a corporation and a user, including a cap on liability, the terms of an indemnity on the part of a user to the corporation and the requirement of a user to maintain insurances to the reasonable satisfaction of the corporation. [Regulation 41 amended: Gazette 20 Jan 2006 p. 378; 31 Mar 2006 p. 1338-41.] Part 8 — Other matters [42. Deleted: Gazette 25 Aug 2006 p. 3499.] 43. Prudential requirements (1) A user other than the Electricity Generation and Retail Corporation must provide and maintain a bank guarantee in a form and with a bank acceptable to a corporation under which the corporation may draw in aggregate an amount equal to or more than the amount last nominated by the corporation for the purposes of this regulation under subregulation (2). (2) Subject to subregulation (3), a corporation may from time to time nominate an amount for the purposes of subregulation (1) by written notice given to the user based on a good faith assessment of the credit risk of the user to the corporation. (3) If — (a) a user fails to pay to a corporation any amount when due under these regulations or an access agreement; or (b) a user pays an amount under these regulations or an access agreement which a corporation is subsequently required to disgorge or repay under laws relating to insolvency, the protection of creditors or similar matters, then the corporation may exercise its rights under the bank guarantee in respect of that amount. [Regulation 43 amended: Gazette 31 Mar 2006 p. 1336 and 1338‑40; 27 Dec 2013 p. 6477.] 44. Title to electricity (1) Title to, and risk in, electricity which is transferred to the electricity transmission network passes to a corporation at the time it passes through the relevant connection. (2) Title to, and risk in, electricity which is transferred from the electricity transmission network passes from a corporation at the time it passes through the relevant connection to the user in respect of the connection. (3) This regulation does not affect an obligation of the user, arising under Part 4 or otherwise, to pay any charge relating to the transport of the electricity. [Regulation 44 amended: Gazette 28 Dec 2001 p. 6719; 31 Mar 2006 p. 1338‑9.] 45. Assignment of access agreements (1) A user must not — (a) assign, novate, declare itself a trustee of, or otherwise dispose of, any of its rights under an access agreement or a grant of access under clause 2 of Schedule 5 to the Act (as in force before the repeal of that Schedule by the Electricity Transmission and Distribution Systems (Repeal and Related Provisions) Regulations 2007); (b) subcontract the performance of its obligations under an access agreement or a grant of access under clause 2 of Schedule 5 to the Act (as in force before the repeal of that Schedule by the Electricity Transmission and Distribution Systems (Repeal and Related Provisions) Regulations 2007); (c) create an encumbrance over any of its rights or obligations under an access agreement or a grant of access under clause 2 of Schedule 5 to the Act (as in force before the repeal of that Schedule by the Electricity Transmission and Distribution Systems (Repeal and Related Provisions) Regulations 2007), without the prior written consent of a corporation (such consent not to be unreasonably withheld). (2) Prior to giving any consent under this regulation, a corporation may require any assignee or person having the benefit of an encumbrance to enter into documents in form and substance satisfactory to the corporation agreeing to be bound by the terms of the access agreement. (3) A corporation may assign all of its rights and obligations under an access agreement to any person who may own or operate all or any part of the electricity transmission network.
