Energy interests are preparing for another battle at the Minnesota Legislature over a proposed mandate that major utilities gather up to 4 percent of their electricity from the sun by the end of 2025.
After six hours of debate, the state House late Tuesday narrowly passed a bill that would make Minnesota the 17th state to promote solar power with a mix of mandates and incentives. Republicans tried to defeat the bill, and utilities said it would be too expensive.
Now, another Capitol faceoff is expected Friday when the Senate considers the solar legislation.
Supporters say a mandate would promote clean energy, boost employment in the state's solar industry and reduce greenhouse gas emissions.
"If we are to do something to save our future, we are going to have to move aggressively," DFL Sen. John Marty, the chief sponsor in the Senate, said in an interview.
But in the face of political resistance, Marty's solar bill dials back the mandate. It would require 1 percent solar in 2025. By comparison, the House bill's 4 percent requirement would be one of the more ambitious solar electricity standards in the nation.
Marty's bill also wouldn't force utilities to spend up to 1.3 percent of their revenue on incentives to those who install solar arrays at their homes and business. That incentive survived in the House bill despite Republican objections that low-income utility customers would end up subsidizing solar arrays on the homes of people who can afford such projects.
If the bill passes in the Senate, it faces a battle in a conference committee where competing interests get another shot at it.
