(Minneapolis, MN)  —  XCel Energy’s plan to close its coal plants by 2030 is approved after receiving a unanimous vote of approval from state regulators.  The energy company proposed the “Alternate Plan” last summer and called for the closures along with the addition of up to four-thousand-650 megawatts of renewable energy over the next ten years.  It also includes plans for two transmission lines that would connect western Wisconsin and southeast Minnesota to the existing grid.  The Minnesota Public Utilities Commission says XCel’s plan will help keep energy costs low for customers.  Environmentalists are applauding XCel’s plan.
