Electricity: integrated resource plans: energy storage systems: modeling.

Existing law requires the Public Utilities Commission to adopt a process for each load-serving entities to file an integrated resource plan and a schedule for periodic updates to the plan and to ensure that load-serving entities, among other things, ensure system and local reliability on a near-term, mid-term, and long-term basis and maintain a diverse portfolio of energy resources. This bill would require the commission to ensure that diverse energy storage duration classes are modeled, as specified, and authorize energy storage technology that meets an energy storage class's minimum duration requirements to be modeled within that class to ensure technology neutrality. Under existing law, a violation of any order, decision, rule, direction, demand, or requirement of the commission is a crime. Because a violation of a commission action implementing the bill's requirements would be a crime, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
