Citation These regulations may be cited as the Energy Coordination (Gas Tariffs) Regulations 2000. 2. Commencement These regulations come into operation on the relevant day as defined in section 25(3) of the Gas Corporation (Business Disposal) Act 1999. 3. Areas to which regulations apply These regulations apply to the supply of gas in — (a) the Mid‑West/South‑West area; or (b) the Albany area; or (c) the Kalgoorlie‑Boulder area. 4. Terms used (1) In these regulations, unless the contrary intention appears — Albany area means the supply area or parts of a supply area to which a distribution licence — (a) granted to the Gas Corporation; and (b) applying to land any of which is in the local government district of Albany, applied when it was first granted; capped tariff has the same meaning as in regulation 5; dwelling means a house, flat, home unit or other place of residence; Kalgoorlie‑Boulder area means the supply area or parts of a supply area to which a distribution licence — (a) granted to the Gas Corporation; and (b) applying to land any of which is in the local government district of Kalgoorlie‑Boulder, applied when it was first granted; Mid‑West/South‑West area means the supply areas or parts of a supply area to which any of the distribution licences of the Gas Corporation, other than a licence referred to in the definition of Albany area or Kalgoorlie‑Boulder area applied when first granted; supplier means the holder of a trading licence; supply, in relation to gas, means the sale of gas transported through a distribution system; unit means 3.6 megajoules. (2) For the purposes of these regulations a supply of gas is for residential purposes if the gas — (a) is supplied to — (i) a dwelling; or (ii) a place, other than a dwelling, to which the supply of gas is separately metered; and (b) is solely for residential use. [Regulation 4 amended: Gazette 24 Jul 2012 p. 3392.] 5. Supplier to have at least one capped tariff (1) A supplier intending to supply gas in an area referred to in regulation 3(a), (b), or (c) is required to have at least one capped tariff for any supply of gas in that area. (2) In subregulation (1) — capped tariff means a tariff under which the charge for a supply of gas in any period for which a charge is calculated under the tariff cannot exceed the charge for that supply that would be calculated and, where applicable, adjusted under Schedule 1. [Regulation 5 amended: Gazette 18 Oct 2002 p. 5224.] 6. Gas to be offered to certain small use customers at capped tariff [(1) deleted] (2) A supplier is required to offer to supply gas to each of its existing standard contract customers under the terms of the customer's existing contract but at a capped tariff unless the existing contract already entitles the customer to be supplied at a capped tariff. (3) In subregulation (2) — existing standard contract customer means a small use customer who is supplied with gas under a contract that, under section 25(1) of the Gas Corporation (Business Disposal) Act 1999, the customer is to be regarded as having entered into. (4) When offering to supply gas to a new customer under a standard form contract, a supplier is required to offer to supply gas at a capped tariff. (5) In subregulation (4) — new customer means a small use customer to whom a supplier offers to supply gas for the supply of which the customer does not already have a contract; standard form contract has the meaning given in section 11WB of the Act. (6) This regulation does not prevent the supplier and customer from agreeing to charges or other terms and conditions that are different from those required by this regulation to be offered.

Calculation of amounts (1) In calculating an amount under Schedule 1, an amount calculated by reference to a rate expressed in cents per unit or cents per day is to be rounded to the nearest one hundredth of one cent except if it falls halfway between 2 consecutive one hundredths of one cent, in which case it is to be rounded to the nearest even one hundredth of one cent. (2) In calculating a charge for the supply of gas, an amount that is not a whole number multiple of 5 cents is to be rounded to the nearest whole number multiple of 5 cents except if it falls halfway between 2 consecutive whole number multiples of 5 cents, in which case it is to be rounded to the nearest even whole number multiple of 5 cents.
