U.S. wind power is becoming more widespread and costs are generally on the decline, but the sector is troubled by policy uncertainties, a new report from the Energy Department says.   After a lackluster year in 2013, wind power capacity additions in the U.S. rebounded nearly 8% in 2014, driven by recent improvements in the […]

The attorneys general of 17 states are suing the Environmental Protection Agency (EPA) for invalidating agency-approved state implementation plans (SIPs) governing emissions from power plant startup, shutdown, and malfunction (SSM) operations. The states have asked a federal court to review the EPA’s June-issued final rule, which deems SIP provisions concerning SSM operations in 36 states […]

On August 3, 2015, the Environmental Protection Agency (EPA) released a much-anticipated suite of regulations, featuring the final Clean Power Plan’s guidelines for carbon dioxide (CO2) emissions from existing power plants under Clean Air Act section 111(d). This package has sparked great interest, and early reactions run the gamut from enthusiastic support to entrenched opposition. […]

Though most power generators and states might have preferred to not deal at all with a new rule regulating greenhouse gas emissions, the final Clean Power Plan (CPP), released August 3, gives most of the power industry most of what it asked for in terms of revisions to the 2014 proposed plan. In any regulatory […]

Reaction from utilities, environmental groups, and governmental leaders following the August 3 release of the Environmental Protection Agency’s (EPA’s) final Clean Power Plan rule was mixed. Some, such as Duke Energy CEO Lynn Good, pointed to the progress that has already been made in recent years to reduce carbon dioxide (CO2) emissions, noting that the […]

Editor’s note (Aug. 3): Adds compliance cost details, key changes The Environmental Protection Agency’s (EPA’s) final Clean Power Plan will seek to tamp down the nation’s carbon dioxide (CO2) emissions from the power sector by 32% from 2005 levels by 2030—about 9% more ambitious than its original proposal. The first-ever final national standards to limit […]
