The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix.

[5] The plant employs a proprietary concentrating solar power (CSP) trough technology developed by Abengoa, and covers an area of 1,920 acres (780 ha).

Nevertheless, the Sierra Club supported the Solana plant, because it was built on private land, and was projected to use "75 to 85 percent less water than the current agricultural use.

"[8] Arizona Public Service (APS) has contracted to purchase 100% of the power output generated from Solana, to meet the Arizona Corporation Commission's (ACC) mandate that the state's regulated utilities provide 15% of their electricity from renewable energy sources by 2025.

[15] Nearby photovoltaic power station Agua Caliente, covering a larger site area of 2400 acres, had a Loan Programs Office projected generation of only 559 GW·h (instead yielding an average real 727 GW·h production).

A CSP thermal power block is like that of a coal or gas-fired plant, except its fuel is sunlight and require up to four years to ramp-up to 100% operating level.
