A joint venture between Ansaldo Energia and ABB has won an $80m deal to boost Italy’s transmission network.
The order from transmission system operator Terna will see Ansaldo design, supply, commission and maintain three asynchronous compensator sets rated at 250 MVAR each: two in the southern city of Matera and one in the eastern coastal town of Manfredonia.
ABB will supply, install and commission the entire electric system to connect the compensator sets to the grid, including protection and control systems, plus monitoring and diagnostic solutions.
Commissioning of the project is due to be completed in 2020.
Ansaldo explained that synchronous compensators are a special application of electric generators and are connected to the transmission network to increase the inertia of the system, its short-circuit power and stability.
“This is a particularly significant goal in an electric system where the contribution of conventional grid-connected generating capacity has decreased in recent years, while renewable sources characterized by a discontinuous power supply on the rise, particularly in the south of the country.
This project unites Italian excellence and specialist expertise in rotating machines and electric and automation systems.”
The contract also includes maintenance and assistance activities for a period of ten years.
