LADWP acts as the project manager and has balancing authority at the point of delivery of energy at the Mead 230 kV Substation in Southern Nevada. SCPPA Participants entered into agreement with Ormat Nevada, Inc. in 2012 to purchase energy from the Don A Campbell 1 facility.
The facility consists of one Organic Rankine Cycle (ORC) power generating unit with a nameplate capacity of 25 MW. The ORC unit contains a high-pressure and an intermediate-pressure system. Each high-pressure unit also contains a recuperator, which scavenges additional heat from condensate exiting the air-cooled condenser. The high-pressure and intermediate-pressure organic vapor turbines for the ORC unit are connected in tandem to a common, 25 MW generator. Heat input to the ORC unit comes from geothermal wells drilled at the project site. Heat is rejected to atmosphere through multiple air-cooled condensers. The net electrical production of the facility is fed into a step-up transformer and from there flows through a generator tie-line into Nevada Energy's transmission system.
Production for this site is above the estimated annual expectation of 135,000 MWh. Similarly, 2016 is trending above previous years.
