Iowa regulators on July 3 upheld the state's Alternative Energy Production law requiring utilities to purchase 105 MW from renewable sources at a 33-year fixed rate of six cents. But despite the ruling, the situation remains in limbo. Although the Iowa Utilities Board (IUB) on July 3 gave MidAmerican Energy Co and IES Utilities a six month deadline to sign contracts purchasing renewables, almost a month later the regulators had yet to issue their formal decision requiring utilities to proceed. Wind lobbyists also expect the utilities to sue to halt the law. The company with most at stake is Zond Systems Inc which hopes to build a 60 MW wind farm.
