July 30 (Renewables Now) - Regional electric utility Arizona Public Service Company (APS) on Monday announced plans to launch tenders for up to 150 MW of solar and 250 MW of wind power capacity.
The company will seek bids in two separate Requests for Proposal (RFPs), which will be issued by September 15, 2019. The first one will target proposals for APS-owned solar resources that will be put into service by 2021. The photovoltaic (PV) schemes need to contain an option for battery storage integration, APS said.
The second solicitation will seek proposals for wind power plants with targeted commissioning as soon as possible, or 2022 at the latest.
The tenders will be held to support APS’ goal of expanding its renewable energy portfolio to around 2,500 MW by 2021, which will be enough to supply roughly 500,000 homes in Arizona. According to its website, the portfolio currently includes biomass, biogas, solar PV, concentrated solar power (CSP), wind and geothermal power plants.
The two competitive rounds will be overseen by an independent monitor. Phoenix-based APS, which serves about 2.7 million people in Arizona, said it will provide additional information about each tender in the coming weeks.
