State Grid Corporation of China has had talks with US power firm AES Corporation about taking a controlling stake in its US wind power business, three sources said, as China’s cash-flush state-owned power companies go on an overseas buying spree. It wasn’t clear how much State Grid would pay for the assets or how the business would be structured after the sale. Based on analysts’ estimates, the assets could be worth around $1.65 billion. The deal involves wind power assets with capacity of around 1,100 megawatts (MW) and would give State Grid a roughly 80 per cent stake in AES’s US wind power business, sources with direct knowledge of the matter said. It would be State Grid’s first foray into the United States. The sources declined to be named as they were not authorised to speak with the media. China’s cashed up state power groups have been scooping up bargains, with dominant power distributor State Grid establishing a presence in the Philippines, Brazil and Portugal. One driver for such deals is a tightly regulated Chinese market that holds down profits for power firms, said Shi Pengfei, vice president of the Chinese Wind Energy Association. “Because domestic electricity prices are controlled by the government, expanding overseas could help power companies’ profits,” said Shi. The company’s president Liu Zhenya visited the United States earlier this month as part of a delegation accompanying Chinese Vice President Xi Jinping. Two of the sources said the companies signed an agreement during that trip, but the third source said a deal is still at the negotiation stage. “The specific details of the American wind power project are still under negotiation,” said that source, who is familiar with the talks. AES Wind Generation, a wholly-owned part of AES Corp, operates more than 1,800 MW of wind power generation capacity in the United States, China and Europe. Of that, nearly 1,346 MW is in the United States, according to the company’s website. The company has wind power assets in Texas, California, Oregon, Minnesota, Iowa, West Virginia and Pennsylvania. Arlington, Virginia-based AES, which has a market value of $10.5 billion, did not immediately respond to requests for comment, and State Grid’s media official declined to comment when reached by phone.
