Minnesota Power and Wisconsin’s Dairyland Power Cooperative announced plans to co-develop a combined cycle natural gas–fired power plant, a 550-MW facility designed to provide backup power for the utilities’ efforts to expand their use of renewable energy sources. The Nemadji Trail Energy Center would be built along the Nemadji River in Superior, Wis., a location […]

Mississippi Power’s Kemper County integrated gasification combined cycle (IGCC) project is now expected to be in service by the end of June, but the company expects it will need post in-service improvements. It also said timing of when it will file a case to address the recovery of costs not currently reflected in rates is uncertain. […]

Kansas City Power & Light Co. (KCP&L) plans to retire five coal-fired generating units at two stations by the end of next year. It will also close, by December 31, 2019, a unit that was just converted from coal to gas last year. The decision is part of “the company’s commitment to a sustainable energy […]

Southern Co. announced yet another lag beyond a new in-service date for its Kemper County integrated gasification combined cycle (IGCC) project. Along with concerns about delays and mounting cost increases afflicting the plant’s coal gasification component are how it will be used in the face of cheap gas prices. The company’s subsidiary Mississippi Power last […]

Inspecting the internal condition of a turbine generator is an important maintenance activity, but tearing a unit apart is a long and expensive process. Borescope inspections offer one way to minimize work

Two nuclear plants owned by Exelon Corp. in Illinois and Pennsylvania failed to clear PJM Interconnection’s latest annual capacity auction, putting one of those financially crippled units at risk of early retirement. Meanwhile, procurements for solar, wind, and demand response fell dramatically compared to last year, and drastic price declines could roil the market for […]

The flood of cheap Marcellus Shale gas driving massive construction of new natural gas power generation capacity could wreak havoc in the PJM power market, Moody’s Investors Service suggests in a new report. Two of the nation’s largest power markets, Texas and California, already pose a “distressed environment” for unregulated power companies owing to declining […]

Sitting on a panel during the Bloomberg New Energy Finance Summit in New York City on April 24, Michael Bloomberg proclaimed that carbon capture and storage (CCS) is “total bullshit.” That statement was not received well by Trude Sundset, CEO of Gassnova, Norway’s state enterprise for the development of CCS. “There’s a whole new world […]

As Dynegy moved this week to assume full ownership of two struggling Ohio coal plants it co-owns with AES Corp. subsidiary DPL Inc., the company’s CEO reportedly said it is mulling withdrawing its presence from downstate Illinois owing to the state’s intervention to keep its nuclear plants running. Dynegy CEO Robert Flexon told Crain’s Chicago Business […]

Rain and snow has returned to California, ending the record-setting drought with record-setting precipitation. The drought led to forest fires, dead orchards, and brown lawns. It also took a big bite out of ratepayers’ wallets and increased global warming emissions, due to the loss of low-cost, zero-emission hydropower. In a study released April 26 by […]

Natural gas supply and price, along with lower electric demand and the growth of renewables, have been far more responsible for the decline in the U.S. coal industry than environmental regulations, according to a new study by Columbia University’s Center on Global Energy Policy and the Rhodium Group, a New York consulting firm. That means […]
