Newswire Renewables Now in June, citing a Spanish daily, that Iberdrola was seeking a buyer for its 50-MW Puertollano solar power plant in Spain's Castilla-La Mancha, adding that the plant could fetch between 100 million euros (£88 million) and 150 million euros ($115.6 million-$173.5 million).

ContourGlobal, which has been beefing up its renewables portfolio, said in February it had agreed to buy Spanish engineering and renewable energy firm Acciona solar power plants in a deal worth 962 million euros.

ContourGlobal, which has been embroiled in a tussle with The World Bank, said last week that it would proceed with plans to build a 500 megawatt (MW) coal-fired plant in Kosovo despite the World Bank's decision not to back the project.

British power producer Drax said on Tuesday it would buy a group of Scottish gas, hydro and pumped storage power plants from Iberdrola for 702 million pounds ($922 million).

Shares of ContourGlobal, which has 100 power plants around the world, were up 5.7 percent at 184.9 pence by 0812 GMT on the London Stock Exchange.
