Sierra SunTower
Location: CA
Operator: eSolar Inc
Configuration: 5 MW collector
Operation: 2009
System supplier: eSolar
T/G supplier: GE
Quick facts: The Sierra plant was launched on 5 Aug 2009 near Lancaster, CA and was the first full-scale installation of this modular, solar collector plant design. This 20ac facility uses 24,000 mirrors and two receivers, each atop a 160ft tower. A refurbished 1947 GE T/G set is the prime mover The scale-up is to 46-MW power units covering about 160ac, each with a steam T/G set and condenser cooling system.

Solar-II
Location: CA
Operator: Southern California Edison Co
Configuration: 10 MW collector
Operation: 1996 (ret 1999)
System supplier: SCE, DOE, Lummus
T/G supplier: GE
EPC: Bechtel, TIC
