Bouygues is to design and build a power station in Gibraltar.
The French construction giant’s Energies & Services business was awarded a €100M (£76M) contract by the Gibraltar Electricity Authority.
Bouygues will also supply equipment to the 80MW power station, and will operate and maintain the dual-fuel plant for one year.
Work will include civil engineering, procurement of electrical and mechanical components, and commissioning.
Bouygues Energies & Services chairman Jean-Philippe Trin said: “This new contract proves the strength of Bouygues Energies & Services as a global operator on major energy-production infrastructures.
“This state-of-the-art power plant will be capable of using gas or light fuel oil and will operate in cogeneration mode in order to be as efficient as possible.
“It will guarantee energy self-sufficiency for the Rock of Gibraltar’s 30,000 inhabitants for the next 30 years.”
Site works, which will involve 150 employees at peak periods, will begin in August 2015, with handover scheduled for 2017.
