HOLLAND, MI (WHTC) - Lost in Monday’s recommendation by the Holland BPW board of across-the-board rate hikes of electrical, water and sewer services was another endorsement of improving the environmental footprint of the Tulip City’s utility. Pending approval by the Holland City Council, a 20-year-contract with the Michigan Public Power Agency would nearly double the BPW’s share of wind-generated power from 15 megawatts to nearly 32 megawatts. It’s part of the utility’s ongoing energy portfolio diversification, according to General Manager Dave Koster. The cost of under a nickel per megawatt is very favorable to nearly a dime per megawatt of such energy a few years ago. Utilities in Michigan must have 10 percent of their energy portfolio be from renewable sources by 2015.
