The Santa Rosa Thermal Power Station has three plants:
The UTI plant came into operation in 1982, until now operating primarily as a peaking and emergency power plant.
It has an effective capacity of 103.35 MW. It is composed of two identical simple cycle groups and mounted outdoors. These groups are made up of units that are based on aircraft propulsion mechanisms.
Until 2006, the plant operated only on Diesel-2. After its conversion, it ran on natural gas until June 2009. Thereafter it was converted to a dual-fuel system operating on Diesel 2 and natural gas.
It began commercial operations with a new turbine in December 2014. The plant has operated with a natural gas turbine-generator and water injection since its conversion in 2005. The unit can also run on Diesel-2.
The plant works with a German-made gas turbine that began operating in 2009. It has 188.21 MW of effective capacity and runs on natural gas.
