49. When fixing or modifying rates for the transmission of electric power or for the transmission, delivery or storage of natural gas, the Régie shall, in particular,(1) determine the rate base of the electric power carrier or of the natural gas distributor after giving due consideration, in particular, to the fair value of the assets the Régie considers prudently acquired and useful for the operation of the electric power transmission system or of a natural gas distribution system, as well as to the unamortized research and development and marketing expenditures, commercial programs, pre-operating costs and working capital required for the operation of such systems;
(2) determine the overall amounts of expenditure the Régie considers necessary for the provision of the service, including, as concerns all rates, expenditures attached to commercial programs and, as concerns transmission rates, expenditures attached to transmission service contracts entered into with another enterprise for the purpose of allowing the electric power carrier to use its own electric power transmission system;
(3) allow a reasonable return on the rate base;
(4) favour measures or incentives to improve the performance of the electric power carrier or a natural gas distributor and the satisfaction of consumer needs;
(5) ensure that financial ratios are maintained;
(6) consider the cost of service, the varying risks according to classes of consumers and, as concerns natural gas rates, the competition between the various forms of energy and the maintenance of equity between rate classes;
(7) ensure that the rates and other conditions for the provision of the service are fair and reasonable;
(8) consider the sales forecasts;
(9) consider service quality;
(10) consider such economic, social and environmental concerns as have been identified by order by the Government;
(11) maintain, subject to any government order to the contrary, uniform rates throughout the territory served by the electric power transmission system; and
(12) consider, as concerns the rates for the transmission of natural gas, the excess transmission capacity referred to in subparagraph a of subparagraph 3 of the first paragraph of section 72.
