U.S. Geothermal Inc., a developer, seller and producer of geothermal energy, said that its engineering, procurement and construction (EPC) contractor, TAS Energy Inc., has started performance testing on the new 8.6 MW San Emidio power plant in Nevada.
Performance testing includes guaranteed output, capacity, reliability and continuous operation tests that the plant must pass to achieve both commercial operation under the power purchase agreement and substantial completion under the EPC contract.
The plant has undergone component commissioning during the past three weeks and has operated at generation levels of up to 9 MW net, 12 MW gross. During commissioning and performance testing, all power generated is sold under the PPA at a rate of $50 per megawatt-hour until commercial operation is achieved. Upon acceptance of commercial operation by NV Energy (NYSE: NVE), the power rate will increase to $89.75/MWh with a 1 percent annual escalation.
