Siemens today announced it has received an order to supply major components for the Altamira combined-cycle cogeneration power plant in Mexico. When complete, the facility will have an electrical capacity of around 350 MW and will also provide process steam, making it the largest private cogeneration project to date for Siemens in the country.
The Altamira plant will be constructed in the state of Tamaulipas in northeastern Mexico. Siemens' will supply one SGT6-8000H gas turbine, one SST-800 steam turbine, one SGen6-100A generator, and one SGen6-2000H generator. The gas turbine and SGen6-2000H generator will be manufactured at Siemen’s U.S. production facility in Charlotte, North Carolina. The steam turbine will be manufactured in Goerlitz, Germany, while the SGen6-100A generator will be manufactured in Erfurt, Germany.
The order also includes four gas-insulated switchgear units: three with a voltage level of 230 kV and one with a voltage level of 115 kV. Three of the switchgear units will be used in the new power plant, with the fourth ensuring a smooth connection to the Mexican grid. Alpek will utilize the electricity and process steam from the new plant for its industrial production and feed excess electricity into the Mexican grid.
The facility is scheduled for commissioning in late 2018.
"[This is] not only the largest private cogeneration project for Siemens in Mexico, but also the first order for an SST-800 industrial steam turbine from the country,” said José Aparicio, head of sales for Latin America within the Siemens Power and Gas Division. “Therefore, this is a breakthrough success for us in the changing Mexican energy market.”
Including this order, Siemens has now received orders for seven H-class gas turbines from Mexico. In addition to the Altamira order, Siemens has also sold six model SGT6-8000H gas turbines in Mexico, with two each going to the 770-MW Empalme I, the 791-MW Empalme II, and the 615-MW Valle de México II combined-cycle power plants.
In total, Siemens has sold 79 H-Class turbines worldwide. With 25 units currently in commercial operation, the SGT-8000H fleet has already achieved more than 250,000 fired hours.
