Regulators are asked to balance a societal need with the cost burden placed on those who pay for the service. Sometimes they forget that it’s other people’s money at stake.

Competition among offshore wind turbine vendors vying for market share went into overdrive in the first three months of 2011 as several key players announced gigantic new turbine models.

The U.S. Court of Appeals for the Ninth Circuit recently dealt another setback to the use of Section 216 of the Federal Power Act, which gives the Federal Energy Regulatory Commission (FERC) “backstop” authority to site electric transmission lines. Although enacted in 2005, this authority has never been used by FERC, and it can be questioned whether it ever will be used.

It’s not just hard finding good help these days. It’s hard finding honest help, too.

A major technical advance in hydroelectric dam safety was achieved this March as Alstom’s Chinese arm, the Tianjin Alstom Hydro Co. (TAH), delivered what it called “the world’s first self-closing electronic ring gate control system” to the Ahai hydropower project in China.

If coal is to be a viable long-term fuel for a significant percentage of electricity generation, research and development is needed to increase thermal efficiency, demonstrate cost-effective and secure carbon dioxide capture and storage, further improve emission controls, and reduce water demands.

Researchers at Sandia National Laboratories say a project that focuses on supercritical carbon dioxide (CO₂) Brayton cycle turbines is moving to the demonstration stage.

The U.S. Environmental Protection Agency is developing a number of new regulations for the power sector governing air emissions, cooling water intake structures, and coal combustion waste disposal methods. Combined, these regulations have the potential to drive as much as 40% of existing coal-fired generating units to retire in the next 10 years, representing about 51 GW.

Like most forms of generation, solar power has its disadvantages. Two cited most by critics of photovoltaic (PV) or concentrating solar power facilities are that they require large expanses of land and that solar cell fabrication and maintenance costs are high. Several companies have been assessing a new approach to tackling these factors: installing solar plants on water.

The question concerning coal plant retirements forced by looming regulatory rules, low gas prices, and moribund load growth has changed from “Why?” to “How many plants?” Many highly detailed analyses and reports have been written on the subject by superbly qualified analysts. This approach to estimating potential plant closures is much more qualitative, and much easier to understand. However, the results closely align: About 50 GW are threatened.

ABB, BHEL to Deliver $1.1B Multi-Terminal UHVDC Line in India. Zurich-based ABB and Indian state-owned company Bharat Heavy Electricals Ltd. (BHEL) said on March 23 that they had been selected by Power Grid Corp. of India Ltd. (PGCIL) to deliver an ultrahigh-voltage direct current (UHVDC) transmission system to convey hydropower from northeastern India to the […]

Twenty-five years ago last month, engineers and technicians were running low-power tests at the 1,000-MW Reactor No. 4 of the Chernobyl Nuclear Power Plant outside Kiev. They quickly, inexplicably, lost control of the light-water-cooled, graphite-moderated reactor. In an instant, the critical chain reaction flared out of control. The plant exploded like a small, dirty bomb, the graphite caught fire, and the worst catastrophe in civilian nuclear power was under way.

Increasing regulatory requirements and a focus on reducing carbon emissions in the U.S. have significantly reduced the number of new coal-fired plants under development compared with past years. In addition, projected capital costs for new coal-fired plants have risen sharply in the past year, while those for natural gas combined-cycle and combustion turbines have stayed relatively flat. In order to keep coal a viable energy source, many countries, including the U.S., are seeking ways to improve plant efficiency while reducing carbon emissions.

The challenges of using Powder River Basin (PRB) coal are as significant as the rewards. The subbituminous coal contains lower amounts of sulfur dioxide than bituminous coal but can be prone to combustible dust explosions if it is not properly managed. To eliminate such hazards, plant personnel need to establish best practices for the safe operation and maintenance of PRB coal-handling and -storage systems based on best available technologies.

The Roosevelt Island Tidal Energy (RITE) pilot project used six full-scale hydrokinetic turbines to capture the power of river tides and currents and convert it into electricity. Located in New York City’s East River, it is the first and only grid-connected tidal array project in the world. RITE project developers are seeking approval to install up to 30 additional turbines in the near future.

The events in Japan, including the catastrophic destruction of a major nuclear power station, remind us of something we don’t like to think about: how to manage a physical disaster. But manage we must.

In Part III of this three-part report, we look at plant- and fleet-level metrics used to determine compensation. As expected from this EUCG-sponsored benchmarking survey, there is broad use of quantifiable metrics to set portions of compensation, but the metrics selected vary substantially across the surveyed utilities. More surprising was the number of utilities that used no performance metrics as part of their employee compensation packages.

While China seems determined to exploit its current control over the market for rare earths and other minerals critical to high-tech and green energy technologies, and while governments engage in conventional hand-wringing and head-scratching, markets appear to be reacting in the ways that markets are supposed to react.

The new Wheelift Self-Propelled Modular Transporter increases safety in spent fuel cask transport and alignment for NUHOMS-type ISFSI installations by reducing worker exposure because only one person is needed to operate the transporter from between 30 feet and 50 feet away. The transporter’s omni-directional steering and 10-inch lift capability enables the same operator to perform […]

For many energy analysts and policy makers, efficiency is the Holy Grail, the universal solvent, the way to effortlessly reconcile supply and demand while simultaneously serving the needs of the environment. Don’t build new power plants, says policy guru Amory Lovins; gather "negawatts" instead. President Obama says that Americans "can save as much as 30% of our current energy usage without changing our quality of life."

A Georgia administrative law judge has remanded an air permit for LS Power’s proposed 1,200-MW Longleaf coal-fired power plant to the state Environmental Protection Division (EPD). The judge found that the permit did not sufficiently limit pollution and ordered the regulatory body to amend the permit to include federally approved tests for five air pollutants.

Entergy Corp.’s Vermont Yankee nuclear power plant hit another hurdle on Tuesday as the Vermont Electric Cooperative (VEC) rejected a 20-year power purchase contract at below market prices.

An annual report released on Tuesday by the U.S. Energy Information Administration (EIA) that assesses energy and technology market trends forecasts that if current laws and regulations remain unchanged, natural gas and renewables will see strong growth in the electricity sector. The report also suggests that expected regulations from the Environmental Protection Agency (EPA) will have an impact on the U.S. power sector, most notably on its fleet of coal-fired power plants.

The Canadian province of Saskatchewan on Tuesday approved construction of a C$1.24 billion project that will integrate and demonstrate carbon capture and storage (CCS) at an aging Boundary Dam Power Station unit near Estevan.

The nuclear crisis at Fukushima Daiichi could increase costs for existing and future nuclear power plants, increase scrutiny on relicensing procedures, and cause a reevaluation of the entire spent fuel management system, researchers from the Massachusetts Institute of Technology (MIT) said as they released a comprehensive report on the future of the nuclear fuel cycle.

Last week, lawmakers from Indiana approved a bill that could allow utilities to charge consumers costs incurred to extend the lives of nuclear reactors, and on Tuesday, Iowa legislators voted to begin the process of developing a new nuclear plant.

As much as 55% of Unit 1’s reactor core at the quake-stricken Fukushima Daiichi nuclear power plant is thought to be damaged; Unit 2’s core is estimated to be 35% damaged, as is 30% of Unit 3’s core, the Tokyo Electric Power Co. (TEPCO) said today. Seven weeks after the crisis began, the utility—which has also admitted damage of the spent fuel rods at Unit 4—continues all efforts to cool the affected reactors.

An internal investigation has shown that hydrogen gas, which had not been fully purged from the generator during unit maintenance at the coal-fired L.V. Sutton Steam Electric Plant in New Hanover County, N.C., ignited and caused an explosion that killed one worker on March 15, Progress Energy said in a statement.

The Department of Energy (DOE) on Monday announced a conditional commitment for a $2.1 billion loan guarantee to support Units 1 and 2 of Solar Trust of America’s Blythe Solar Power Project. The two-unit 484-MW concentrating solar thermal plant will be built near Blythe, in Riverside County, Calif.

Plans to build and operate the Cape Wind project nearly 5 miles offshore in Nantucket Sound, Mass., were approved on Tuesday by the Department of Interior’s Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE). Cape Wind Associates now says that construction of what could be the first U.S. offshore wind farm could begin as early as this fall, but the controversial project must still overcome several hurdles.
