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 […]

King Coal has lost his crown—at least temporarily. Electricity generation data from the Energy Information Administration (EIA) for April 2015 showed the U.S. generated 92.5 TWh from natural gas and 88.8 TWh from coal, the first time the nation has gotten the largest share of its power from anything other than coal. That represents a […]

Five of Germany’s largest lignite power plants will be mothballed to allow the country that is already phasing out nuclear power to meet ambitious climate goals by 2020.  In what it called a “milestone decision,” the government on July 2 agreed to scrap plans to impose a controversial—and by some accounts, illegal—climate tax for conventional […]

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 […]

China on June 29 submitted its Intended Nationally Determined Contribution (INDC) for reducing carbon emissions to the United Nations in preparation for the COP21 climate negotiations in Paris later this year. The INDCs are formal pledges toward a hoped-for binding agreement. The Chinese pledge builds on its November agreement with the U.S. In its INDC, […]

Controlling combustion in fossil fuel power plants in order to control the emission of pollutants sometimes has adverse effects on plant equipment, including certain metals. To understand how to address the problem, it helps to understand how it develops. The emission of nitrogen oxides, generally referenced as NOx (NO or NO2), has several adverse effects […]

With plans already approved for the closure of 12 of its coal ash basins, Duke Energy on June 23 recommended the full excavation of 12 additional basins located in North Carolina. The company proposed excavating five basins each at its Cape Fear Plant in Moncure and its H.F. Lee Plant in Goldsboro. Additionally, it recommended […]

Boiler slagging and fouling, and the resulting frequent operation of sootblowers, are some of the major operations and maintenance factors that can negatively affect power plant reliability and efficiency. Boiler slagging and fouling are among the most common causes of maintenance headaches at coal-fired power plants. Though you cannot totally eliminate the problem, following proper […]

A group of Illinois state lawmakers are proposing legislation to discourage the import of Powder River Basin (PRB) coal into the state, making locally mined coal more appealing to power plants. The coal competitiveness plan being proposed would modify regulations that allow electric utilities to pass through the cost of transportation to customers. According to […]

Electricity generation from existing coal-fired power plants will increase from 2012 levels through 2025, according to the Reference case presented in the U.S. Energy Information Administration’s Annual Energy Outlook 2015, released on April 14.

As it decided in a February case involving American Electric Power (AEP), the Public Utilities Commission of Ohio (PUCO) has denied Duke Energy Ohio’s request to charge ratepayers for power from two aging coal plants owned by the Ohio Valley Electric Corp. (OVEC).  In an April 2 order, the state regulator approved the Duke Energy […]

A Gallup poll completed last month found that only 32% of adults in the U.S. worry a “great deal” about global warming or climate change, while 45% worry “only a little” or “not at all.” The survey was taken via telephone interviews conducted during the first week of March using a random sample of 1,025 […]

When the decision is made to retire a power plant, the work of getting there is just beginning. Maintaining safe and reliable generation requires strong leadership, clear communications, and heightened attention to operations and maintenance, staff morale, and post-shutdown plans.   For utilities and other generators facing the challenge of winding down operations at an […]

The U.S. Energy Information Administration (EIA) released 2015 scheduled capacity additions and retirements on Mar. 10, and the news was not good for the coal industry.
