Rules proposed by the U.S. Environmental Protection Agency (EPA) that could require operators of new and existing boilers burning coal, oil, natural gas, and biomass to install a “maximum achievable control technology (MACT)” and limit air pollutants were revised on Friday to offer more flexibility.

Days after the North American Electric Reliability Corporation (NERC) warned in a new assessment that new federal air quality rules could stress the nation’s power grid, the Department of Energy (DOE) released its own report examining the potential impact of two standards on electricity reliability. Those rules would prompt the closure of 29 GW of coal-fired capacity, but they should not create resource adequacy issues or unmanageable reliability challenges, the DOE finds.

A Texas District Court today dismissed two appeals challenging air quality permits granted by the Texas Commission on Environmental Quality (TCEQ) last December for the 600-MW coal-fired Tenaska Trailblazer Energy Center under development near Sweetwater in Nolan County.

A structure or mechanical system that requires fasteners also demands tools to maintain it properly. In power sectors such as wind, fossil fuel, and nuclear, some work areas may be several hundred feet in the air. While working at those extreme heights, or even just 10 feet off the ground, it’s simply unacceptable to drop anything. That’s why the concept of “tools at height” is being embraced as a way to improve safety and efficiency on the worksite.

Hendrix Wire & Cable, a provider of overhead and underground power distribution products, introduced its Spacer Cable Systems, a “green” solution for overhead distribution circuits. Because Spacer Cable is more compact and can withstand temporary contact with branches without causing outages, Hendrix Spacer Cable Systems can help reduce the amount of vegetation that must be […]

Inlet fogging systems for combustion turbines achieve their effect at the molecular level: The cooling effect occurs by converting thousands of gallons of water into single evaporated molecules suspended in the air. The right fog pattern comes down to a matter of selecting the best nozzle design and proper placement in the inlet air stream.

Energy professionals and the general population are both acutely aware of the explosion of a Pacific Gas & Electric Co. (PG&E) natural gas pipeline in San Bruno, Calif., that led to the death of eight people and the total destruction of 38 homes in September 2010. The tragic accident garnered immediate national attention, thrusting the natural gas industry into the spotlight. The California Public Utilities Commission’s (CPUC) Independent Review Panel neatly encapsulated the sentiment surrounding the event: “The fact that a large segment of pipe literally blew out of the ground in an urban neighborhood and the residents were generally unaware of the proximity of a high-pressure natural gas transmission system to their homes—raises significant public safety concerns.”

Owner/operator: EnBW Energie Baden-Württemberg AG/EnBW Renewables GmbH Germany’s first commercial offshore wind farm—the 48.3-MW EnBW Baltic 1—consists of 21 Siemens wind turbines, each with a capacity of 2.3 MW and a rotor diameter of 93 meters. Siemens constructed the facility in an area covering about 7 square kilometers in the Baltic Sea.

The wind power industry has exploded over the past decade. In the U.S. alone, almost 40,000 MW of wind power have come online since 2000. As more wind generation has been added, grid operators have been challenged to integrate a large amount of intermittent generation. As the state with by far the most installed wind power capacity, Texas has had to face this problem head on.

The EPA’s proposed rules on limiting greenhouse gas emissions from new, modified, and existing power plants has taken another step forward.

The 5-MW Kimberlina Solar Thermal Energy Station is the first to use compact linear Fresnel reflector technology developed to generate continuous superheated steam, a key element for higher-efficiency power generation and integration with new and existing plants. The facility’s innovative technology helps deliver power even during periods of transient cloud cover.

After three years of development, dozens of public workshops, and hundreds of meetings with stakeholders, the California Air Resources Board (ARB) on Oct. 20 adopted a final rule to cap California’s greenhouse gas emissions and put a price on carbon. The cap-and-trade program starts in 2013 for electric utilities and large industrial facilities.

The 75-MW Martin Next Generation Solar Energy Center is the first hybrid solar facility in the world to combine a solar thermal array with a combined cycle natural gas power plant. Because the facility uses a steam turbine, transmission lines, and other infrastructure from an existing combined cycle unit, financial savings of approximately 20% were achieved compared to what a similar stand-alone solar plant would have cost.

ICF International, a consultancy group that earlier this year had predicted 68 GW of coal-fired power plants could retire by 2030 as a result of finalized and proposed regulations from the Environmental Protection Agency (EPA), downgraded its retirement projections to 50 GW this fall.

Germany’s government has decided to shutter all 17 of its nuclear plants (23 reactors); eight plants are now closed for business, six more will be closed by 2021, and the final three will close by 2022. What is lacking is an honest discussion of the rising cost Germans will pay for electricity for what The Economist describes as “the greatest change of political course since unification.”

In December 2009, construction of an underwater tower and fish collection structure was successfully completed at the 465-MW Pelton Round Butte Hydroelectric Project. The first-of-its-kind fish bypass and intake structure returns temperatures in the lower Deschutes River to historic patterns and restores downstream passage of Chinook, steelhead, and sockeye salmon while maintaining existing generating capacity.

Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change.

The world’s biomass power facilities, not counting those in the pulp and paper industry, average just 18 MWe to 20 MWe. In the U.S., passage of the Public Utility Regulatory Policies Act of 1978 ignited development of many existing biomass plants. Greenhouse gas rules and renewable policies around the world have kindled a new generation of much larger biomass facilities. New announcements routinely are for plants 50 MW or larger, presumably to leverage economies of scale.

The 80-MW Sarnia Solar Project is the world’s largest operational photovoltaic plant, with 1.3 million solar modules. The facility utilizes First Solar’s proven thin-film photovoltaic (PV) technology, which has the lowest environmental footprint and the fastest energy payback of current PV technologies.

As China’s economy continues to soar, its energy use and greenhouse gas emissions will keep on soaring as well—or so goes the conventional wisdom. A new analysis by researchers at Lawrence Berkeley National Laboratory now is challenging that notion, one widely held in both the United States and China.
