The technology group Wärtsilä will supply the engines with auxiliaries for a 75 MW power plant being built in Termoli, on the Adriatic coast of Italy. The plant has been contracted by energy utility Metaenergiaproduzione, and is under construction by FATA SpA, a member of the Danieli Group. The fast-starting Wärtsilä solution provides efficient grid balancing, enabling the utility to participate in Italy’s capacity market designed to promote the use of renewable energy sources. The plant will be on call by Terna, the national transmission system operator, to supply energy on demand to compensate for fluctuations in supply from solar and wind sources. The Wärtsilä engines can reach full output within minutes of start-up.The entire delivery scope includes four Wärtsilä 50SG engines featuring high efficiency and fuel economy, plus auxiliaries, control panels, technical advisory services, the operators' interface system, and commissioning. The engines will be operating on natural gas. Wärtsilä engines are ready to also operate on sustainable fuels in the future, once they become widely available, which makes them a future-proof solution. Already today Wärtsilä engines can use synthetic and carbon-neutral methane and methanol, as well as hydrogen blends. Sustainable fuels together with engines can serve long-term energy storage needs for periods with persistently low wind or solar conditions.The Wärtsilä equipment is scheduled for delivery in early 2023, and the plant is expected to become fully operational a few months later.
