The Renewable Portfolio Standard

The Renewable Portfolio Standard

June 30, 2011 | By Keith Martin in Washington, DC

The renewable portfolio standard in Arizona is legal, a state appeals court said in April.

Arizona requires electric utilities to supply at least 25% of their electricity from renewables by 2025. The standard was set by the Arizona Corporation Commission, which regulates utilities. Customers of Arizona Public Service challenged the authority of the state regulators to impose such a standard.
