A power increase of 43 MW, an efficiency improvement of 0.9%, and a reduction of more than 10,000 tons of CO₂ emissions per year: these were the expected results of the upgrade recently completed by Ansaldo Energia at Alpiq’s San Severo combined-cycle power plant (FG). The first operational tests, however, have already demonstrated even better performance than initially anticipated.
The project, completed within the agreed timeframe, involved the gas turbine, steam turbine, and generator, while also enhancing operational flexibility. In addition, the plant will now be able to operate with up to 25% hydrogen, contributing to Italy’s decarbonization goals.
In operation since 2011, with a capacity of around 400 MW and able of supplying electricity to nearly 1 million households, the Alpiq’s San Severo plant is one of the most modern combined-cycle facilities in Southern Italy. It generates electricity while providing essential grid stabilization services. Thanks to the recent upgrade, the plant strengthens its role as a flexible and highly efficient asset supporting both national energy security and the energy transition.
“This project represents a fundamental step in ensuring the security and flexibility of Italy’s power system,” said Massimiliano Bignami, Country Manager Italy at Alpiq. “The upgrade strengthens the strategic role of the San Severo plant, already qualified in the capacity market, contributing to grid stability and the integration of renewable sources.”
“We are grateful to Alpiq for the trust placed in us with this important project,” said Reto Furrer, Executive Vice President Thermal Service at Ansaldo Energia. “As the Original Equipment Manufacturer of the key components, Ansaldo Energia has provided its expertise and advanced technologies to ensure the plant is ready to meet the challenges of the energy transition and an ever-evolving power market.”
