Alstom has been awarded a contract worth over €300 million by TERNA Rete Italia, a company fully owned by TERNA, the Italian electricity transmission system operator, and Réseau de Transport d'Électricité (RTE), its French counterpart, to build two HVDC converter stations for the transmission link between France and Italy.
Alstom will design, manufacture and commission two converter stations (2x600 MW, +/- 320 kV) containing Alstom's VSC MaxSine Voltage Source Converter technology. Alternating Current (AC) will be converted from each country's electrical network into Direct Current (DC) for transmission and vice versa. Key equipment will be manufactured in Alstom's facilities in the UK, Germany, France and Italy and the contract also includes maintenance for the converter station in France.
This is Alstom's third VSC project in the last three years, following on from Sweden's South West Link, a multi-terminal HVDC grid connecting central and southern networks in the country and the Dolwin3 project, connecting 900 MW offshore wind energy from the North sea to the German grid. Alstom is also in the process of executing large scale HVDC projects such as India's Champa 1 & 2 (800 kV) and Brazil's 600 kV Rio Madeira, which at almost 2400km, is the world's longest transmission line.
