LONDON, June 18 (Reuters) -
* UK-based Lightsource BP , Europe's biggest solar energy developer, has completed its first big solar project in India, it said on Monday.
* The project in the Indian state of Maharashtra can generate 60 megawatts (MW) of electricity at its peak, enough to power around 20,000 homes.
* India is one of the fastest-growing markets for clean energy.
* The project was financed in partnership with UK Climate Investments - a joint venture between Macquarie MQG.AX owned Green Investment Group and the British government's Department for Business Energy and Industrial Strategy.
* The company did not reveal any details on the cost of the project.
* Oil major BP BP.L acquired a 43 percent stake in Lightsource last year.
* India currently has around 60 gigawatts (GW) of installed renewable capacity, but plans to add a further 115 GW by 2022, which could cost $125 billion.
