Samsun, Turkey, September 28, 2010 – Wartsila, a global supplier of decentralized power plant solutions, has been awarded an engineering and equipment contract relating to the extension of the Aksa Samsun power plant in Samsun, Turkey.
The natural gas fired unit has an electrical output of 18,321 kW. This will be the first installation of the Wartsila 18V50SG unit, which features a power plant efficiency rating of over 50 percent in combined cycle mode.
The scope of supply also includes the controls, automation and auxiliary equipment related to the fuel gas, charge air, cooling and exhaust gas systems.
The Aksa Samsun combined cycle plant, owned by AKSA ENERJI, currently operates using seven Wartsila 18V46 engines running on heavy fuel oil, six of which will be converted to Wartsila 18V46GD engines for gas-fired operation.
When the Wartsila 18V50SG engine has been commissioned in 2011, the power plant will have a total electrical output of about 130 MW in combined cycle mode, which will be fed to the national grid.
“In converting the Aksa Samsun facility from HFO to gas-fired operation, we are providing added environmental sustainability, while the efficiency level of the new Wartsila 50SG engine sets a new benchmark for the industry,” commented Christer Strandvall, Regional Director, West Europe, Wartsila Power Plants.
Wartsila already has a presence in Turkey’s energy market, and expects to have delivered close to 3 GW of power generating capacity by the end of 2011. Some 85 percent of these power plants will be running on natural gas.
The Wartsila 18V50SG is a four-stroke, spark-ignited gas engine that works according to the Otto process and the lean burn principle. The engine has ported gas admission and a pre-chamber with a spark plug for ignition. The engine runs at 500 or 514 rpm for 50 or 60 Hz applications, and produces 18,810 and 19,260 kW of mechanical power respectively. At generator terminals, this corresponds to 18,321 kWe and 18,759 kWe of electrical power.
