Initially known as Imperial Valley Solar 1, Mount Signal was part of a 700+MW proposed series of projects on federal land owned by now-bankrupt developer Tessera, which was ultimately brought to its knees (alongside sister company Stirling Energy Systems) by financial and legal challenges.
AES Solar – a solar-energy joint venture owned by power giant AES and the private-equity firm Riverstone Holdings – acquired the projects in 2011, and brought on co-developer 8minutenergy.
