The project pipeline also includes the 50-MW St. Mary Clean Energy Center waste heat project in Louisiana, 171 MW of solar, and 34 MW of hydro. Another 775 MW are expected to be retired, leaving the region with a net gain of 7,788 MW.Among the capacity set to be retired, WEC Energy Group Inc. plans to shut the 359-MW Presque Isle coal plant in Marquette County, Mich., in May due to unfavorable economics and competition from natural gas. The 312-MW Henderson William L. Newman Station 2 Generation Plant owned by the Henderson (Ky.) City Utility Commission is also scheduled to shut in February.About 48% of the new capacity is in advanced development or under construction, as defined by S&P Global Market Intelligence. Some of the new combined-cycle facilities under construction are Entergy Corp.’s 945-MW St. Charles Power Station in Louisiana and Alliant Energy Corp.’s 732-MW West Riverside Energy Center in Wisconsin.The larger renewable energy projects in later stages of development are mostly wind. Those projects include 468 MW from a combination Alliant Energy’s Upland Prairie Wind Farm (New Wind) and the English Farms I Wind Project (New Wind), which the company is building as part of a plan to add 1,000 MW of wind in Iowa by 2020. Out of the 171 MW of new solar, about 31% are in Minnesota, while the rest are planned in five other states.More ($): ISO Outlook 2019: Wind makes up nearly three-fourths of new MISO power supplylast_img
