National Power, the parent company of one of the UK's leading wind energy developers, is to split its operations into two separately quoted businesses. The de-merger, to take place in financial year 2000/1, will separate National Power's UK operations from its international business. The new British company, to be named "npower" will retain its UK generating power plant and retail business -- and National Wind Power, its wind development arm. The other company, International Power, will take on its interests in 22,100 MW of overseas plant, including wind farm assets in the USA. These wind farms, however, will continue to be managed by American National Wind Power, which will remain a subsidiary of npower, like its UK sister company National Wind Power.
