Wärtsilä has been awarded a turnkey contract by the Salvadorian electrical development group Sociedad Electrica de CEREN (SEC) for a 17.5 MWe diesel CHP plant. To be installed at Hacienda de San Andrés in San Juan Opico in the Departamento Libertad, El Salvador, the plant is due to be handed over in the third quarter of 2009.

The new SEC plant, Termoeléctrica de CEREN, is the first Wärtsilä ‘OilCube’ power plant to be ordered since the introduction of the product in spring 2007, says the company. It will comprise two OilCubes, each with a Wärtsilä 20V32 diesel engine burning heavy fuel oil. The value of the contract is approximately €12 million.

The plant will include a waste heat recovery system consisting of two exhaust gas boilers capable of producing a total of 6000 kg/h of saturated steam.

Electricity from the new CEREN plant will be delivered through a new electrical substation to the Salvadorian national grid through Unidad de Transacciones, which is the national entity in charge of managing the wholesale energy market in El Salvador. SEC also plans to sell part of its electricity production directly to private industrial customers. The steam will be delivered to a local industrial park to be used in industrial processes.
