Renewables’ share of the global power mix is slated to overtake coal to become the largest source of electricity by 2040, the International Energy Agency (IEA) projects in its 2014 edition of the World

The growth in natural gas–fired generation in the U.S. since 2007 has overwhelmingly displaced coal-fired generation, according to a report from the Breakthrough Institute released Dec. 15. Consistent with the impressions of power sector observers, but in contrast to previous claims by environmental groups that growth in gas is offsetting renewables and nuclear while coal […]

A final rule issued today by the Environmental Protection Agency (EPA) to regulate coal combustion residuals (CCRs) from coal power plants clarifies technical requirements for coal ash landfills and surface impoundments nationwide under Subtitle D of the Resource Conservation and Recovery Act (RCRA), the nation’s primary law for regulating solid waste. The final rule is […]

The Environmental Protection Agency’s (EPA’s) proposed carbon rules for existing power plants amassed more than 1.6 million remarks before the public comment period ended on Monday. Here’s a snapshot of what states, regulators, industry groups, and environmental alliances told the agency about its Clean Power Plan.  States Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, […]

E.ON—a major investor-owned energy supplier that manages facilities across Europe, Russia, North America, Brazil, and Turkey—announced this week that it will embark on a new corporate strategy focused on renewables, distribution networks, and customer solutions, while combining its power generation, global energy trading, and exploration and production businesses into a new, independent company. “We are […]

Recent months have seen a violent shakeup of India’s coal supply sector and may result in the end of a 40-year-old government monopoly on mining and selling coal. The development could be a boon for

Australian Prime Minister Tony Abbott’s Direct Action Plan, the policy mechanism proposed to replace the coal-rich country’s now-defunct carbon trading program, cleared the Senate despite staunch

In recent years several EPRI projects have explored different aspects of heat rate improvements. This article, following Part 1 in the November 2014 issue of POWER , reviews results of implementing heat rate

Material-handling systems at coal-fired power plants operate nearly continuously in harsh conditions for decades. Temperatures, moisture, overload conditions, and collisions from equipment can take a toll on

Closure and remediation solutions for coal ash ponds, or impoundments, vary greatly. Assuming the U.S. Environmental Protection Agency (EPA) promulgates the expected proposed Subtitle D regulations, technical

The Environmental Protection Agency (EPA) on Wednesday proposed to revise the national ambient air quality standards (NAAQS) for ground-level ozone to a range of 65 to 70 parts per billion (ppb) and sought comments on a level as strict as 60 ppb. The proposed level applies to primary (health-based) and secondary (welfare-based) ozone standards, but […]

The U.S. Environmental Protection Agency’s (EPA’s) Mercury and Air Toxics Standards (MATS) have been seen by many in the coal-fired power industry as potentially more expensive and onerous than its Clean Power Plan, which addresses greenhouse gases. On Nov. 25, the Supreme Court agreed to review a consolidated case that could potentially prevent the MATS […]

The Environmental Protection Agency (EPA) on Wednesday finalized changes to the Mercury and Air Toxics Standards (MATS), applying to periods of startup and shutdown at new and existing coal- and oil-fired power plants nationwide.  As published in the Federal Register on Nov. 19, the final action on the EPA’s reconsideration of the startup and shutdown […]

China on Wednesday issued a key energy strategy that sets obligatory 2020 targets for renewables and nuclear power use and urges increased natural gas consumption—but which also caps coal consumption.  The State Council’s Energy Development Strategy Action Plan covers the period between 2014 and 2020. It caps annual energy primary consumption at 4.8 billion metric […]

The U.S. Census Bureau released data on Nov. 18 showing that revenues for electric power generation industries that use renewable energy resources grew 49% from 2007 to 2012, while fossil fuel electric power generation industry revenues decreased 6.7% during the same time period. Fossil fuel revenues continued to dwarf renewable totals, bringing in $79.7 billion […]

The Obama administration’s Clean Power Plan could result in the retirement of between 3.3 GW and 8.7 GW of coal-fired capacity in the Electric Reliability Council of Texas (ERCOT) grid and jeopardize electric reliability for the state that is already power strapped, the independent system operator (ISO) says in a new analysis.  The Environmental Protection Agency’s […]

The Southern Environmental Law Center (SELC) informed the Tennessee Valley Authority (TVA) on Nov. 10 that it intends to bring suit under the Clean Water Act to stop the release of coal ash pollutants it says are leaking from the TVA’s Gallatin coal ash ponds into the Cumberland River.
