Dr. Allison Macfarlane, an expert on nuclear waste issues and a member of the Blue Ribbon Commission on America’s Nuclear Future, was on Monday sworn in as the 15th person chosen to lead the Nuclear Regulatory Commission (NRC). She will serve a term ending June 30, 2013.

About 700 nuclear engineers on Monday joined 144 others in a strike that has lasted more than a month, after failing to reach a labor pact with Candu Energy, a subsidiary of Canada’s SNC-Lavalin Group.

The U.S. House of Representatives on Monday passed H.R. 5892, the Hydropower Regulatory Efficiency Act, by a vote of 372–0. The bipartisan bill—championed by Reps. Cathy McMorris Rodgers (R-Wash.) and Diana DeGette (D-Colo.)—seeks to facilitate the development of small hydropower and conduit projects and direct the Federal Energy Regulatory Commission (FERC) to study the feasibility of a streamlined two-year permitting process. The legislation now moves to the Senate.

The Environmental Protection Agency (EPA) last week promulgated a final rule that does not revise the greenhouse gas (GHG) permitting thresholds that were established in Step 1 and Step 2 of the GHG Tailoring Rule. The final rule, which comes just days after a federal appeals court ruled the EPA was “unambiguously correct” in its interpretation of the Clean Air Act to regulate carbon dioxide emissions, is the third step of the agency’s phased-in approach to GHG permitting under the Clean Air Act.

Utilities in the Canadian province of Alberta were on Monday forced to institute rolling blackouts as soaring summer temperatures drove demand for electricity to an all-time high and six generators–four coal plants and two natural gas plants–entered unplanned outages.

New York’s State Department of Environmental Conservation (DEC) last week adopted rules that set limits on carbon dioxide emissions from new power plants as well as require new or expanding electric generating facilities in that state to evaluate the potential disproportionate impacts on nearby environmental justice communities.

In a bid to spur the construction of new power plants and offset a power crunch, the regional grid operator has forecast, the Public Utility Commission (PUC) of Texas last week voted to raise the wholesale price cap for electricity prices on Aug. 1 by 50%, to $4,500/MWh from $3,000/MWh.

A settlement to resolve alleged violations of the New Source Review (NSR) provisions of the Clean Air Act reached between the Dairyland Power Cooperative (DPC), federal entities, and the Sierra Club will force the Wisconsin utility to invest about $150 million in pollution control technology, retire three coal units at its 210-MW Alma Station, and pay a civil penalty of $950,000.

The Environmental Protection Agency (EPA) on Tuesday granted PNM a 90-day stay in the effectiveness of the federal plan that would force the Albuquerque, N.M.–based utility to install pollution controls at its 1,800-MW San Juan Generating Station by September 2016 to meet visibility requirements of the Clean Air Act in New Mexico.

The Department of the Interior (DOI) on Monday announced the release of final environmental impact statements for a proposed wind power complex in Wyoming with a nameplate capacity of 3,000 MW and publication of an environmental assessment for commercial wind leases and site assessment activities on the Outer Continental Shelf (OCS) offshore Rhode Island and Massachusetts.

Siemens Infrastructure & Cities and Munich city utility Stadtwerke München (SWM) this April put into operation a virtual power plant (VPP), linking several small-scale distributed energy sources and pooling their resources so they can be operated as a single installation (Figure 1). The project comes on the heels of a February 2012 expansion of a […]

Within the two months since the Department of Energy (DOE) flourished $452 million in cost-shared federal funding to support engineering, design certification, and licensing from the Nuclear Regulatory Commission (NRC) for up to two small modular reactor (SMR) designs over five years, four developers of reactors under 300 MW have submitted applications: Westinghouse, Babcock & […]

India’s long-term annual economic growth rate is projected at over 7%, and the country is investing in its hydroelectric, nuclear, and renewable resources. However, the primary fuel used to produce electricity remains coal, and the government has ambitious plans to significantly increase coal-fired capacity. Those plans have been challenged by a number of unexpected factors that threaten to stifle India’s economic growth.

A two-year project begun this April by Southern Co. and a consortium of partners including boiler vendors Alstom, Babcock & Wilcox, Foster Wheeler, and Riley Power; the Electric Power Research Institute (EPRI); and the Oak Ridge National Laboratory will gather data on the performance of alloy materials under advanced ultrasupercritical (USC) temperatures of about 1,400F. […]

A West Coast combined cycle plant that uses reclaimed water found that cycling 300 times a year caused disruptions to the plant’s cooling water chemical treatment program. The solution was a performance-based monitoring and control system that uses available plant operating data plus algorithms to measure corrosion rates and fouling factors, which in turn allows the plant to trim chemical feed rates so they correlate with a specified corrosion rate, rather than a suggested chemical residual.

In May—as a trade war raged between Chinese solar panel manufacturers and exporters and their counterparts in the U.S. and the European Union concerning the world’s plummeting crystalline silicone photovoltaic module prices—a 28.8-MW thin-film copper indium gallium (di)selenide (CIGS or CIS) solar power plant came online. Developers Solar Frontier, the world’s largest manufacturer of CIS […]

Power generators typically allocate construction risks through the process of aversion. Owners have a tendency to shift risk to a project’s primary contractor, who in turn pushes it to lower-tier parties in the contracting arrangement. Research by the Construction Industry Institute has found that there are more equitable ways to allocate project risk.

The Republic of Korea’s National Assembly on May 2 passed legislation that will mandate cuts in greenhouse gases (GHGs) starting in 2015. The Act on Allocation and Trading of Greenhouse Gas Emissions Allowances passed with a near unanimous vote of 140-0, with three abstentions. It follows the country’s voluntary GHG emissions reduction target of 30% […]

Panelists at the ELECTRIC POWER Keynote and Roundtable Discussion in Baltimore in May wrestled with a range of issues. But despite calls for a “balanced portfolio,” an “all-of-the-above” energy strategy, and predictions of “more changes in the next 10 years than in the last 100,” the focus of attention appears to be the decidedly mundane displacement of coal by natural gas.

The second of Georgia Power’s three natural gas combined cycle units at Plant McDonough-Atkinson in Smyrna, Ga., came online on April 26 (Figure 7). The first unit at the plant became operational in December 2011, and the third unit, currently under construction, is expected to come online in November 2012, increasing the plant’s capacity from […]

Panelists at ELECTRIC POWER discussed how U.S. utilities choose renewable power generation technologies based on their geographic locations, state requirements, economics, and other criteria—including reliability and federal regulations.

UK Unveils Draft Energy Reform Bill. A draft energy bill unveiled by the UK’s Department of Energy and Climate Change on May 22 seeks to attract £110 billion ($168 billion) of investment to build new nuclear, renewables, and carbon capture and storage (CCS) plants to replace nearly a fifth of the country’s total power capacity, […]

As U.S. utilities seek to increase the percentage of carbon-neutral biomass used in their generation portfolios, they must deal with a number of complex challenges unique to this fuel source. Several breakthrough technologies are poised to help promote greater use of biomaterials.

The Federal Energy Regulatory Commission (FERC) has the responsibility for ensuring just and reasonable rates and preventing undue discrimination by public utility transmission providers. Last year FERC defined a new framework for public utilities and regional transmission organizations planning new transmission networks. The framework is provided in Order No. 1000—Transmission Planning and Allocation by Transmission Owning and Operating Public Utilities. The Final Rule was issued on July 21, 2011, and reaffirmed by Order No. 1000-A on May 17, 2012.

Efforts by power producers to meet clean air rules mean that wastewater effluent streams now face revised EPA regulations. A skirmish involving a New Hampshire power plant could set the tone for the next battle over regulations.

Practically everyone would agree that the energy policy of the U.S. is in a great state of flux. Not since the introduction of commercial nuclear power some five decades ago has our country come to such an energy crossroads. No matter what your political ideology, no one can refute that conventional coal-fired power plants are being paralyzed by recent and potential U.S. Environmental Protection Agency (EPA) regulations designed to cut the nation’s reliance on coal.

With new reactors finally under construction, this should be an optimistic time for nuclear power in the U.S. But cheap natural gas, rising construction costs, and the Fukushima accident’s lingering pall have darkened the mood.

The primary considerations in slurry valve selection are reliability in function and design, abrasion resistance, and ease of maintenance. In addition, valves with a straight-through, unobstructed flow minimize the effect of abrasion and therefore reduce the need for maintenance.

The season’s blockbuster includes white-hatted heroes, good-natured regulatory sidekicks, bar fights, and a lurking menace named Fugitive Dust.

California is approaching a tipping point with respect to the near-term economic viability of existing non-utility generation. The procurement policies and practices implemented in response to the statewide energy crisis over a decade ago have evolved into market conditions that do not offer “uncontracted” existing resources with sufficient and stable enough revenue streams to recover going-forward costs. Continued adherence to these policies will subject such resources to an increasing risk of economic retirement, threatening long-term reliability and potentially costing electric consumers billions of dollars.
