Siemens has received an order to upgrade the simple cycle Santo Domingo de los Olleros power plant to combined cycle. The plant is near Lima, the capital of Peru. The customer is Peru-based supplier Termochilca SA. The combined cycle conversion will increase the power output by approximately 100 megawatts (MW). The improved efficiency will reduce the CO2 emissions per megawatt hour by 30 percent. The high-efficiency combined cycle plant offers an environmentally friendly solution to meet the growing power demand in Lima. It is scheduled to start commercial operation in early 2018.
Siemens will be responsible for full turnkey supply of the power plant upgrade, which includes engineering, procurement and construction of the combined cycle conversion. The main equipment to be supplied includes one SST-900 steam turbine, one SGen6-100A generator, a three-pressure heat recovery steam generator, and an air-cooled condenser. The air cooling enables the plant to use much less water. Siemens turned over the Santo Domingo de los Olleros simple cycle plant in 2013, after a construction time of just 19 months. The plant is equipped with an SGT6-5000F gas turbine and currently has an overall installed rating of 200 MW. In the future, the waste heat from the gas turbine will be used to produce power using the additional steam turbine. With this, the power output will increase up to 300 MW with efficiency over 55 percent.
"This order marks a further milestone for our turnkey combined cycle plant business in Peru. We are pleased that Termochilca contracted us for the expansion of the plant and placed their trust in our technology and project management," said Martin Tartibi, Head of Siemens Energy Solutions for the Americas. "The two projects are a good example of our long term focus on Peru and commitment to support the growing power needs of the country."
Santo Domingo de los Olleros power plant is located in the Chilca district in Cañete province, 60 kilometers south of the capital Lima. The power demand in Peru will increase by seven per cent annually according to the regulator of the national power grid (COES) presenting good prospects for fossil- and renewable-based power generation.
"We are pleased to renew our trust in Siemens and their project team. Our decision was based in our recent experience with Siemens during the first stage of the project. That was completed in time and under the estimated budget. And primarily we received an excellent quality of services from Siemens," said Tatiana Alegre, CEO of Termochilca SA.
