51. No electric power transmission tariff or natural gas transmission or delivery tariff may impose higher rates or more onerous conditions than are necessary to cover capital and operating costs, to maintain the stability of the electric power carrier or a natural gas distributor and the normal development of a transmission or distribution system or to provide a reasonable return on the rate base.
The same applies to the storage of natural gas by the operator of a natural gas storage facility insofar as it is warranted by the rate determination method employed by the Régie.
