At closing, NRG will invest approximately US$10 million for equity and associated development rights for three projects on sites in south central California and the southwest of USA and a portfolio of power purchase agreements (PPAs) to develop, build, own and operate up to 11 units of eSolar’s concentrating solar power (CSP) technology.

eSolar is currently completing its first commercial demonstration CSP plant in southern California. The first plant under the agreement with NRG Energy is anticipated to begin producing electricity in 2011.
