; and (bb) appropriate differences between— (AA) retailers operating in organized wholesale markets; and (BB) retailers operating in vertically integrated market contexts; and (II) behind-the-meter generation consumed by electric consumers served by a retail electricity supplier, including by requiring from the retail electricity supplier relevant documentation of behind-the-meter electric energy consumption, such as records associated with net-metering. (ii) Quantifying clean energy For purposes of quantifying clean energy and behind-the-meter generation under clause (i), the Secretary shall use the methods used to assign a quantity of credits to generators under subsection (f). (10) Dispatchable low-emission technology The term dispatchable low-emission technology means a generator that uses a technology or combination of technologies that— (A) has a carbon intensity of not more than 0.05 metric tons of carbon dioxide equivalent per megawatt-hour; (B) has the ability, at any time, to start, increase, decrease, and stop energy production on demand; (C) is placed into service after the date of enactment of this section; and (D) is not a dispatchable zero-emission technology. (11) Dispatchable zero-emission technology The term dispatchable zero-emission technology means a generator that uses a technology or combination of technologies that— (A) has a carbon intensity of zero; (B) has the ability, at any time, to start, increase, decrease, and stop energy production on demand; and (C) is placed into service after the date of enactment of this section. (12) Energy storage system The term energy storage system means any equipment or facility relating to the electric grid that— (A) is capable of absorbing energy, storing the energy for a period of time, and dispatching the energy as electric energy; and (B) uses mechanical, electrochemical, biochemical, or thermal processes— (i) to store energy generated at an earlier time for use at a later time
