Through its affiliate En Plus s.r.l., Alpiq constructed a gas-fired combined cycle power station in San Severo (province of Foggia, Italy) with an electrical capacity of 400 MW. Alpiq has a 100 percent stake. The plant has been in service since February 2011 and it was delivered by the Italian contractor Ansaldo Energia on a turn-key basis.
In addition to the power station, a 22 km gas supply pipeline and a 5.5 km 380 kV high-voltage transmission line were constructed. Alpiq Energia Italia is responsible for the operation and maintenance of the power plant.
Gas-fired combined cycle power stations are characterized primarily by their high level of flexibility, their rapid availability as well as their high efficiency. San Severo power station boasts a net efficiency of 55 percent. After several upgrades to increase its flexibility, the plant is a top performer in the demanding market of ancillary services and it is a key player for the balancing and the stabilization of the grid in an area with a massive renewable penetration.
The power station introduced an environmental management system in accordance with the standard UNI EN ISO 14001:2015. The ISO 14001: 2015 certification, which was entrusted to a nationally accredited third-party organisation, guarantees compliance with the prerequisites defined by the standard as well as their correct implementation.
Since 2013, the power plant was certified by Emas (Eco-Management and Audit Scheme). Members of Emas commit to improving their environmental performance and to publishing an environmental statement in which they report on the (direct and indirect) impact on their environment, their environmental performance and environmental targets.
In 2014, the power plant obtained the certification in accordance with the ISO 45001:2018 regulation, which mandates the continual improvement of its health and safety management system.
In order to retain its certifications, San Severo is subject to annual inspections to ensure that the conditions of conformity relating to its safety and environmental management systems are maintained.
