Solana Generating Station

Gila Bend, AZ

Focusing the Power of the Sun

In a testament to PayneCrest’s steadfast reliability, Abengoa increased PayneCrest’s scope of work 57 fold in the construction of the first-of-its-kind Solana Concentrated Solar Power Plant in Gila Bend, Arizona. The project earned PayneCrest an AGC Keystone Award. Spanning three square miles, Solana is the world’s largest parabolic trough plant. It is the nation’s first large-scale solar plant with a thermal energy storage system allowing it to provide power after sunset. The 250-megawatt (MW) concentrated solar power (CSP) facility reliably serves 70,000 Arizona Public Service (APS) customers.

“Because of PayneCrest’s commitment to fulfilling the expectation for the Solana project, we selected the firm to assist us in building more renewable energy plants in the U.S.” Leonardo Maccio, President, Abeinsa EPC LLC
