British renewable energy firm Blue Energy announced Tuesday that it will build a giant solar power plant in Ghana which it claimed will become the biggest in Africa.

“Blue Energy is to build Africa’s largest solar photovoltaic (PV) power plant”, the company said in a statement, in a move “which could spark a renewable energy revolution in west Africa”.

The 155-megawatt Nzema plant, costing $400 million (305 million euros) to build, will be fully operational in 2015. Blue Energy said there were currently only three other PV plants in the world that are bigger.
