system and rules for measurement and verification of demand reductions; (3) such goals to provide that such entities will reduce or mitigate
peak demand by a minimum percentage amount from the applicable baseline to a lower
peak demand during 2012 and 2015; (4) such goals to provide that the minimum percentage reductions established as
peak demand reduction goals shall be the maximum reductions that are realistically achievable with an aggressive effort to deploy Smart Grid and
peak demand reduction technologies and methods; and (5) each
load - serving entity to prepare a
peak demand reduction plan that demonstrates its ability to meet applicable goals.

«An aggregated fleet of vehicles or chargers can act as a [demand response] resource, shifting
load in response to price signals or operational needs; for example, vehicle charging could be shifted to the middle of the day to absorb high levels of solar generation and shifted away from evening hours when solar generation disappears and
system net
load peaks.»
Previously, solar power plants had depended on back up energy plants powered by carbon emitting fuels because a solar
system's
peak generation hours do not coincide with the utility's
peak load hours after 5 p.m. Low sunlight meant low energy generation, and this challenge scaled back the environmental benefits of solar plants.
