Wärtsilä Corporation, Press release, 14 July 2017 at 10:00 am EEST The technology group Wärtsilä will take full operations and maintenance responsibility for Pampa Energia S.A.'s installation Central Térmica Parque Pilar located in the Buenos Aires province, Argentina. Under the 10-year agreement, Wärtsilä will ensure the reliable electricity generation of the highly efficient Wärtsilä Smart Power Generation installation. The efficient and flexible Wärtsilä engines chosen by Pampa Energia S.A., combined with Wärtsilä's extensive experience in operating large power installations, paved the way for the 10-year operation and maintenance (O&M) agreement, signed in May 2017. Upon completion, the Central Térmica Parque Pilar power plant will have an output of 100 MW. The base load facility is powered by six Wärtsilä 50DF multi-fuel engines and will run primarily on natural gas, with heavy fuel oil as a back-up fuel. The installation is continuously remotely monitored, and the received data serves as the basis for Wärtsilä to constantly evaluate the power plant's performance in order to proactively mitigate any operational deviation, thus preventing and minimising unexpected downtime. Wärtsilä handles risk management and provides Pampa Energia with performance and lifecycle cost guarantees, ensuring efficient and optimised operations. The scope of services includes personnel for operations, spare parts and a full range of maintenance services, from scheduled service activities to predictive and unscheduled maintenance.
