Come September 15, 2019 and Arizona, US based electric utility Arizona Public Service Company (APS) will launch a request for proposals (RFP) for 400 MW of solar and wind power capacity in a bid to expand its renewable energy portfolio to about 2.5 GW by 2021.

The solar RFP will seek competitive proposals for up to 150 MW of solar projects that will be owned by APS and will need to come online by 2021. It must be designed with the option to add an energy storage component sometime in the future.

For the wind RFP, APS will aim for up to 250 MW that needs to be commissioned as soon as possible, but no later than 2022.

APS says both the RFPs will allow commercial customers to partner with it in support of their own sustainability and clean energy goals. The utility will appoint a third-party to independently monitor and review the procurement process.

According to information on the company’s website, APS mainly has nuclear, coal and natural gas power generating stations in its portfolio. As of September 2015, its renewable energy portfolio grew to 1,223 MW comprising solar PV, wind,

In November 2018, another power supplier in the state, Arizona Salt River Project announced plans to add 1 GW of new utility scale solar power capacity by the end of fiscal year 2025 (see Arizona Utility To Add 1 GW Solar By 2025).
