Wartsila has signed a four-year maintenance agreement with Spanish mineral and chemical producer Minerales y Productos Derivados SA (Minersa), renewing an existing contract signed in 2000.

Under the terms of the agreement, Wartsila will optimize the performance of Minersa’s 4.5 MW baseload gas-fired power plant. The firm will also extend the lifecycle of Minersa’s power generation equipment and upgrade the engine control systems with the latest technology.

Minersa’s power plant is located in Asturias in northwestern Spain, where it supplies power to the local mining industry. In addition to Wärtsilä’s maintenance and advisory services, the scope of the renewed agreement covers an upgrade of the control systems for two Wärtsilä 25SG engines. After the upgrade, the engines’ gas consumption is expected to be reduced by over 5 per cent and their lifetimes extended.  

In addition to the efficiency improvement, the upgrade is expected to result in around 5 per cent lower CO2 emissions and improved safety.

José Alonso, managing director of Minersa Fluorspar, which is part of the Minersa Group, said his company “needed a profitable gas technology solution that would improve the engine efficiency and performance of the power plant.

“Furthermore, we were looking for demonstrated cost savings. Lower fuel consumption reduces not only the operating costs of the power plant but also its environmental impact.”
