(1) All-source RFP requirements. All-source RFPs must allow bids from different types of resources that may fill all or part of the characteristics or attributes of the resource need. Such resource types include, but are not limited to, unbundled renewable energy credits, conservation and efficiency resources, demand response or other distributed energy resources, energy storage, electricity from qualifying facilities, electricity from independent power producers, or other resources identified to contribute to an equitable distribution of energy and nonenergy benefits to vulnerable populations and highly impacted communities.

(2) Required RFP. A utility must issue an all-source RFP if the IRP demonstrates that the utility has a resource need within four years. A utility may supplement its all-source RFP with one or more targeted RFPs issued at the same time. The required RFP and any supplemental RFPs are subject to commission approval.

(3) Voluntary RFP. Whenever a utility chooses to issue an RFP to meet resource needs outside of the timing of its required RFP, it may issue an all-source RFP or a targeted RFP. Voluntary RFPs are not subject to commission approval.

(4) Targeted RFP requirements. If the utility issues a targeted RFP in conjunction with an all-source RFP, it must fairly compare all resource options in its combined analysis.
