Although mining practices often vary greatly according to the material produced and the value of the deposit, one common denominator is that mining of materials containing sulfide minerals creates acid mine drainage (AMD). AMD is one of the mining industry’s major environmental challenges.

The UK grid, focused on adding valuable renewable generation, will rely on natural gas–fired generation for many years to come. One of the most recent additions is the Langage Power Plant, designed for quick response and low load “parking” at night while remaining below air emissions limits. With an extraordinary architectural design that blends into the natural surroundings, Langage is now a local landmark.

This summary of results from a recent Platts/Capgemini survey of North American utility executives looks at what respondents had to say about all things related to the smart grid. Nearly half of respondents’ utilities have a smart grid strategy in place, while the other half said their utility has one in development.

The Panoche Energy Center is a 400-MW simple-cycle power plant using four of General Electric’s GE LMS100s with fast-start capability. Dispatched by Pacific Gas & Electric to meet regional power and grid stabilization needs, the project entered commercial service two months earlier than planned. Panoche is the largest LMS100 peaking facility in the U.S.

At the Ras Laffan Power Co. facility, the 756-MW net combined-cycle plant and the integrated 40 million gallons per day desalination plant are working in tandem to provide abundant, reliable electricity and desalinated water to residents of the State of Qatar, the most prosperous nation in the Middle East.

Federal public utility Tennessee Valley Authority on Tuesday said it would idle nine coal-fired power units totaling nearly 1 GW at three power plants starting in 2011. Utility officials said the plans were part of a strategy to replace older and less-efficient coal-fired units with “low-carbon” and “carbon-free” generation.

A bill signed on Thursday by New Jersey’s Governor Chris Christie seeks to meet targets established in the state’s Energy Master Plan for the development of 3,000 MW of offshore wind by 2020.

Florida Power & Light this weekend demolished the most visible structures at its 42-acre Cape Canaveral Power Plant. A video shows the implosion of the 45-year-old plant’s red-and-white stacks. The company said it is preparing to build the Cape Canaveral Next Generation Clean Energy Center—a natural gas plant—which will open in 2013.

Oregon and Washington failed to pass bills before the end of their legislative sessions that would implement the Western Climate Initiative (WCI). That leaves only two U.S. states and three Canadian provinces to participate in the regional greenhouse gas (GHG) cap-and-trade program when it begins in 2012.

Turkey will reportedly start privatizing power generation plants by the end of this month or in early September. Some of the first few plants up for sale include the Hamitabat power station, a 1,120-MW thermal plant that produces 7% of the country’s total electricity output.

By Kennedy Maize Washington, D.C., Aug. 23, 2010 — It’s time to stop fretting about climate change and start worrying about space weather. In an opinion article in the Aug. 15, 2010 New York Times, journalist Lawrence E. Joseph raises the issue of the havoc a major solar storm could have on modern electric power […]

Houston-based Dynegy is to be acquired by an affiliate of private equity firm Blackstone Group in a $542 million deal that includes billions in debt assumption. Under a separate agreement between Blackstone and NRG Energy, NRG Energy could acquire four natural gas-fired assets owned by Dynegy for about $1.36 billion.

A rule proposed by the U.S. Environmental Protection Agency (EPA) on Thursday would certify that 13 states lack the authority to apply Prevention of Significant Deterioration (PSD) permits to greenhouse gas (GHG) emissions under their State Implementation Plans. A second rulemaking action, also issued last week, proposes a federal implementation plan (FIP) under which the EPA would assume the authority to issue PSD permits for GHG emissions in states that lack the authority to do so.

An interagency task force on Carbon Capture and Storage (CCS) established by President Obama this February delivered a series of recommendations  on overcoming barriers to the widespread, cost-effective deployment of CCS within 10 years.

FirstEnergy Corp. last week said it would cut back operations or idle 1,620-MW of coal-fired capacity in Ohio for up to a year to reduce operating costs, while Xcel Energy announced plans to shut down nearly 900-MW of coal-fired capacity to generate a savings of nearly $225 million. Reasons for the cutbacks included the continued slow economy, lower demand in electricity, and uncertainty related to proposed new federal environmental regulations.

The Shaw Group on Monday announced it has signed an initial contract for two new AP1000 units at the Xianning nuclear power plant project in Hubei province with a subsidiary of China’s State Nuclear Power Technology Corp. (SNPTC).

French company GDF Suez formally announced last week it will merge its international business with UK company International Power. The new firm, New International Power, is expected to have over 66 GW in gross operation capacity and 22 GW in the pipeline.

The U.S. Department of Energy (DOE) on Thursday announced it would award $1 billion in Recovery Act funds to a revamped FutureGen proposal. The so-called “FutureGen 2.0” project contemplates repowering of an existing Ameren 200-MW coal unit in Meredosia, Ill., using oxyfuel technology—not construction of an integrated gasification combined-cycle facility at Mattoon, Ill., as originally envisioned. The new project still calls for use of the original Mattoon geologic storage site

to sequester carbon dioxide—however, the city of Mattoon has declined participation

in the project.

The U.S. Occupational Safety and Health Administration (OSHA) on Thursday cited three construction companies and 14 site contractors for 371 alleged workplace safety violations, and issued a total of $16.6 million in penalties. The fines follow an investigation into the causes of February’s deadly natural gas explosion at the Kleen Energy power plant construction site in Middletown, Conn. The explosion killed six workers and injured 50 others.

An Indiana state agency representing utility ratepayer interests in cases before regulatory commissions said it has “serious concerns” regarding cost overruns at Duke Energy’s 618-MW integrated gasification combined cycle (IGCC) facility at Edwardsport.

Xcel Energy claims that preliminary tests of a 1-MW battery-storage technology system shows the technology works. The company announced on August 3 that its wind-to-battery project showed it was possible to reduce the need to compensate for the variability of wind generation.

The U.S. Environmental Protection Agency filed suit against Michigan’s largest energy company, DTE Energy, for alleged violations of the federal Clean Air Act at that company’s  coal-fired Monroe Power Plant in Michigan.

California-based BrightSource Energy in the past week received two key approvals for its 392-MW Ivanpah concentrating solar power (CSP) plant in the Mojave Desert. The California Energy Commission’s (CEC’s) siting committee issued a proposed decision recommending approval, and on Friday, the U.S. Bureau of Land Management (BLM) issued its Final Environmental Impact Statement (FEIS) for the project.

A massive increase in organized “attacks” on the distribution power network in central England has resulted in more than a dozen downed wooden poles and thousands of customers without power in a week, E.ON UK said last week.

Constellation Energy on Monday said it had signed an asset purchase agreement to acquire Boston Generating’s 2,950-MW fleet, consisting of mainly natural gas–fired plants, for about $1.1 billion, or roughly $372/kW.

By Kennedy Maize Washington, D.C., Aug. 9, 2010 –  Washington is abuzz with talk of a lame-duck session of Congress after the November mid-term elections. Many pundits seem to assume that the Democratic leadership will call the solons into session after the elections (with the Democrats having done very poorly, possibly losing their control of […]

When—not if—we pass climate legislation, we will put the U.S. on a path toward a low-carbon electric generation sector. As part of this shift, we’ll need more transmission, including lines to wind and solar power plants that are sometimes located far from today’s power grid. The question is: How do we plan for these new lines and how should we pay for them?

There is an idea that has been around for a long time, at least since the fall of 1973: All that stands between the U.S. and an abundant energy future is a lack of spending on research and development. It is as though the Knights Templar could find the Holy Grail, if only the Pope would commit just a few more resources to the hunt.

Scuttling a high-profile “public nuisance” lawsuit, a federal appeals court has reversed a lower court ruling that required the Tennessee Valley Authority to accelerate plans to install pollution controls at four TVA coal-fired power plants to reduce the amount of pollution blowing into western North Carolina, saying the lower court decision could lead to other public nuisance suits that would wreak havoc on federal and state regulatory regimes for combating air pollution.
