This week brought announcements from India and the state of Wisconsin regarding the repurposing of sites previously associated with coal-fired power generation for future solar power generation. In India’s capital of Delhi, the 240-MW coal-fired Indraprastha Power Station, which was closed in 2010, will be the site of a new 5-MW solar photovoltaic installation. As […]

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 […]

According to data compiled and reported by Fraunhofer-Institut für Solare Energiesysteme ISE—a German-based solar energy research institute—from July 1 through August 5, solar and wind energy produced 6.24 TWh and 7.09 TWh of electricity respectively, compared to 5.94 TWh of nuclear power generation in Germany. Although it’s not the first time wind production has exceeded […]

Renewables giant SunEdison will acquire emerging distributed energy firm Vivint Solar’s 523-MW rooftop solar portfolio in a $2.2 billion acquisition deal that signals momentum for the business model that has challenged the bottom lines of traditional utilities. SunEdison and Vivint Solar signed a definitive merger agreement on July 20. It will involve the acquisition of Vivint […]

Interstate Power and Light (IPL) will be forced to spend $620 million to retire 10 coal-fired units and retire, refuel, or install pollution controls at several others in Iowa under a settlement reached with the federal government.  The Alliant Energy subsidiary has long anticipated the settlement announced on July 15 by the Environmental Protection Agency […]

Many of the dangers existing at conventional power plants also threaten personnel in the wind and solar energy sectors. All workers can benefit by reviewing lessons learned and implementing corrective actions to improve health and safety performance. The expanding wind and solar energy sectors are not immune to industrial hazards affecting all energy generation markets. […]

A new report from the Government Accountability Office (GAO) reveals surprising aspects about how federal subsidies for electricity have been distributed, how the power generation mix has shifted, and how consumption has transformed since 2001.  The June 29–released report, “Generation Mix has Shifted, and Growth in Consumption has Slowed, Affecting System Operations and Prices,” responds […]

Concentrating solar power has found a partner in thermal storage, but costs remain high. Solar photovoltaic generation may have a partner in rapidly expanding battery options, but the economics are uncertain. Is there room for both approaches, or will one be crowded out? Battery storage is officially hip. Once a subject of concern largely only […]

The Department of Interior (DOI) has approved the first three solar energy projects from its Western Solar Plan. The projects total 440 MW and will be built on public lands in Clark County, Nev.  Under the Western Solar Plan, the Bureau of Land Management (BLM) has designated 19 solar energy zones covering roughly 298,000 acres […]
