No additional capacity (MW) will result from the operation of the solar thermal facility.
The Solar Energy Center has an array of approximately 190,000-mirror parabolic troughs on about 500 acres (202 ha) of the Martin County plant.
[6] The solar collectors feed heat to the existing steam plant, displacing gas generated electricity at an estimated rate of 155,000 MWh per year.
[7] The 2012 solar-derived production was about 89,000 MWh of power, according to records filed with the state’s Public Service Commission, which was 42% less than projected when the plant got approval.
[9] Excess pressure and a release of operating fluid led to the plant being shut down for four months in 2011 for cleanup and testing.
