ORIGINAL REPORTING: A Renewables Mandate To Beat The Peak
New Arizona proposal seeks to mandate renewable generation during peak demand hours; A fix to the renewables mandate floated by the state’s consumer advocate would require wind and solar to deliver power when electricity use is highest

Editor’s note: California lawmakers recently added this breakthrough concept to their agenda. And insiders say New York is considering the same step.
An unprecedented proposal from Arizona’s consumer advocate on how to improve the state’s renewables mandate could be a policy whose time has come throughout the nation. Evolving the RPS: A Clean Peak Standard for a Smarter Renewable Future by Arizona’s Residential Utility Consumer Office (RUCO) would enhance a state’s renewables mandate by adding a mandate for renewables to meet peak demand. While the idea is new, its immediate relevance to grid needs across the nation is already attracting attention of regulators, utilities, and important private sector players in other states.
The Clean Peak Standard (CPS) adds more renewables, but it adds renewables when the system most needs capacity so it uses renewables to deal with system cost drivers and saves ratepayers money when electricity prices are highest. Peak power needs can be met by pairing renewable energy with storage or designing wind and solar facilities to deliver power at certain times. The CPS concept is intended to provide that incentive. If it works, it could reduce the system’s need for conventional generation at peak times and eliminate costs for delivering it. It would provide a boost not only for renewables, but for storage and distributed energy companies. Tesla, fresh off its acquisition of SolarCity, endorsed the concept… click here for more
