Arizona utility Commissioner Andy Tobin has called for an audit of the costs and benefits associated with raising the state's clean energy standard, including requiring utilities to get 80% of their electricity from renewables and nuclear by 2050 and deploy 3000 MW of energy storage by 2030.
Tobin's Arizona Energy Modernization Plan also calls for reforms in utility planning processes, policies to boost energy efficiency, electric vehicles and biomass, and the deployment of 3 GW of storage by 2030.
Tobin wants the Residential Utility Consumer Office to conduct "a full audit and benefit-cost analysis" of the Arizona Energy Modernization Plan, specifically comparing it to costs associated with utilities' current integrated resource plans and 15-year forecasts.
