Public Service Commission President Ken Norman said he sympathizes with environmental concerns. "I've got grandchildren," he said. "I think long term, anything we do to clean up the environment" is good. But he's also concerned about the implications of the measure. Wind power is one of the primary renewable power sources now available, though there are other renewables such as solar power and the burning of biomass. But the reliability of wind power - or the lack thereof - is an issue. Wind power only works when the wind is blowing, Norman said. There are no giant batteries to hold the power. It has to be used as it's produced. When the temperatures reach 30 below zero as they do in this area, the power source has to be there, Norman said. "Up here, it's a matter of survival." Complicating matters is the proposed Global Warming Mitigation Act in Minnesota. A provision of that bill would block the Big Stone II coal-burning plant project, State Rep. Morrie Lanning, R-Moorhead, said. Lanning and State Sen. Keith Langseth, DFL-Glyndon, supported the "25 by '25" initiative, but also say that plants such as Big Stone II are needed to supply the on-demand power availability that wind can't. The Big Stone II project includes construction of transmission lines that could also be used to transmit wind power, Lanning said. The kind of renewable sources of energy production proposed by the "25 by '25" initiative are more expensive to operate than coal-burning plants, MPSC officials say. And a great deal of infrastructure will be necessary to supply the requirements of the "25 by '25" legislation.
