APS in Arizona Issues RfP for 400 MW of Solar and Wind Energy Resources

The Arizona Public Service Co. (APS), the largest and longest-serving electric company in the state has announced that it has issued two separate Request for Proposals (RfP) for solar and wind energy resources. These RFPs were first announced in late July with the aim to help the company expand renewable energy portfolio to approximately 2,500 megawatts by 2021 – enough to power more than half a million Arizona homes. The first RFP is seeking competitive proposals for up to 150 MW of APS-owned solar resources to be in service by December 31, 2021. Projects must employ commercially proven technology and must be designed with the flexibility to add energy storage as a future option. The second RFP will pursue up to 250 MW of wind resources to be in service as soon as possible, but no later than 2022. The company will consider both APS-owned resources, as well as those owned by third parties that would sell the output to APS under a power purchase agreement.
