Utilities trying to spinoff their Renewable Energy Subsidiaries have faced a very tough 2011 with many of the plans being scrapped.The Utilities which have managed to list have done so at much reduced valuations and have seen their stock prices erode after listing.Enel Green Power which was the biggest Green Utility to IPO in 2010 managed to to so after massive delays and lowering its stock price 2 times.Orient Green Power in Indian and First Wind Holdings of USA which were pureplay Green Utilities also saw very tough times with First Wind being forced to scrap its capital raising plans.China’s Datang and Huaneng Group which were planning to list their Green Subsidiaries in Hong Kong for a long time faced a big question as well.Both these large state owned utilities have huge wind power assets which are forecast to grow at a tremendous rate over the next decade.The prospects are good for both these green utilities as wind turbine prices have been falling as a result of sharp competition amongst WTG companies in China such as Ming Yang Power.
