The Wall Street Journal ( WSJ) recently reported that 14 of the 29 states that have adopted a renewable procurement mandate are currently considering legislation that would “water down or repeal” the renewable set-aside. Proponents of repeal describe their motivation as simple economics: Renewable power increases costs to electric consumers.

The LM6000 is the most widely used aeroderivative combustion turbine (CT) in the world, with more than 1,000 installations. As with all CTs, power output and heat rate degrade markedly during warm weather. The ARCTIC (Absorption Refrigeration Cycle Turbine Inlet Conditioning) system eliminates this deficiency.

Modern heat recovery steam generator (HRSG) design must balance operating response with the reduction in life of components caused by daily cycling and fast starts. Advanced modeling techniques demonstrate HRSG startup ramp rates can be accelerated without compromising equipment life.

MidAmerican Energy Holdings Co., a unit of Berkshire Hathaway Inc., is buying NV Energy Inc. for $23.75 a share in cash, or around $5.6 billion.

A new bill introduced in the Senate seeks to encourage the development of renewable power and lower consumer costs through the deployment of energy storage technologies.

Jon Wellinghoff, chair of the Federal Energy Regulatory Commission (FERC), announced on Tuesday that he would resign after a seven-year-long tenure at the gas and power market regulator.

Sen. Barbara Boxer (D-Calif.) on Tuesday called for a federal investigation to determine whether Southern California Edison (SCE) intentionally misled regulators regarding the installation of faulty steam generators at the beleaguered San Onofre Nuclear Generating Station.

Cost overruns of nearly $1 billion to build the 582-MW Kemper integrated gasification combined cycle (IGCC) plant in Kemper County, Miss., were underscored on Monday as Mississippi Power’s Board of Directors took the dramatic step of replacing the Southern Co. subsidiary’s leadership.

A carbon tax or cap-and-trade programs could raise trillions of dollars within the first 10 years of their enactment and avert climate change effects, but without accounting for how these revenues will be used, they could take a toll on the U.S. economy, the Congressional Budget Office (CBO) says in a report released on Tuesday.
