Omaha Public Power District commissioned Unit 2 at its Nebraska City Station in May of this year. The new 682-MW unit joins Unit 1, which went commercial 30 years ago in the same month. The project is outfitted with all the requisite air quality control systems and sports a very good thermal efficiency. More importantly, the plant will provide reasonably priced power for customers of eight municipal utilities that share ownership of the plant’s electrical output. Those utilities paid for their portion of the construction cost and now receive a like portion of the electrical output from Unit 2 under a unique participation power agreement.

Hard work was required at the 2,600-MW Rockport Plant to make improvements to equipment, materials, and processes. But that hard work has paid off: The plant’s units operate much better, employee safety has improved, the facility is setting generation records with both of its 1,300-MW units, and it earned the PRB Coal Users’ Group Large Plant of the Year honors.

A reusable organic liquid developed by the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) to remove carbon dioxide (CO₂) or sulfur dioxide (SO₂) from power plant emissions could one day replace current scrubbing methods and allow power plants to capture the gases in a cost-efficient way that uses no water and less energy.

Complying with a corporate environmental policy requires much more than just writing a check for equipment upgrades. It takes a dedicated and knowledgeable staff that’s willing to invest years of work to permanently reduce a plant’s environmental footprint. The staff of Seminole Generating Station have completed multiple, incremental plant improvements over the past decade that have significantly reduced air emissions and minimized solid waste disposal.

Since Robert Stirling invented the Stirling engine in 1816, it has been used in an array of specialized applications. That trend continues today. Its compatibility with clean energy sources is becoming apparent: It is an external combustion engine that can utilize almost any heat source, it encloses a fixed amount of a gaseous working fluid, and it doesn’t require any water — unlike a steam engine.

Italy’s Enel said in August that it has successfully begun operating a power plant in Fusina, near Venice, in the Veneto region of Italy, that is fueled 100% by hydrogen. The industrial-sized plant’s building site was officially opened in April 2008, after which infrastructure and technology work was carried out on schedule. Initial testing of the turbine using methane gas was conducted in the spring of 2009, and now — after completion of the special pipeline — the plant has switched to 100% hydrogen fueling, Italy’s largest energy company said.

Senate Democrats today unveiled the long-awaited 821-page discussion draft of the “Clean Energy Jobs and American Power Act,” a bill touted as “tough on corporate pollution”—but which will “improve the way the nation generates and uses energy,” without raising the “federal deficit by one single dime.”

Exelon Corp. is the third utility to leave the U.S. Chamber of Commerce in the past week, following moves by California utility PG&E Corp. and New Mexico–based PNM Resources. Exelon, the largest nuclear operator in the U.S. cited the “organization’s opposition to climate legislation” for its decision, an allegation the business federation refuted on Tuesday.

Dozens are feared dead after a 330-foot chimney under construction at a 1,200-MW coal-fired power plant collapsed last week in India’s Chhattisgarh state. Teams have so far retrieved 46 bodies from the debris.

A federal appeals board has ruled that the Environmental Protection Agency (EPA) will have to reconsider a long-contested air permit for the $3 billion Sithe Global Desert Rock coal-fired power plant on the Navajo Reservation, saying that the agency abused its discretion by not considering integrated gasification combined cycle (IGCC) technology in its analysis of best available pollution control systems for the plant.

The Electric Power Research Institute (EPRI) has joined American Electric Power (AEP) and Alstom in a validation of advanced carbon dioxide capture and storage (CCS) technologies at AEP’s Mountaineer Plant in New Haven, W.Va. The $76 million project is being watched closely around the world because it will be the first to capture carbon dioxide from a pulverized coal-fired power plant as well as inject it into a permanent storage site more than 7,800 feet underground.

NRG Energy’s proposed 112-MW project to repower its coal-fired Somerset Station in Massachusetts with plasma gasification technology has moved on to the due diligence phase of the Department of Energy’s federal loan guarantee program.

New geothermal projects representing as much as 7,100 MW of new baseload capacity were under development in 14 U.S. states between March and September 2009. When added to the 3,100 MW of existing capacity, these could bring U.S. geothermal capacity to more than 10 GW, a new report from the Geothermal Energy Association (GEA) shows.

By Kennedy Maize In 1979, researcher Renate Kimbrough of the Centers for Disease Control, part of the Department of Health Education and Welfare (now Health and Human Services), shocked the electrical world with an epidemiological study. She found that GE employees from the transformer works at Schenectady, N.Y., exposed to high levels of polychlorinated biphenyls […]

In a decision that experts say could have profound implications on the future of climate change litigation, a two-judge panel of a federal appeals court on Monday reversed a 2005 district court decision and ruled that eight states and New York City can sue coal-burning utilities for creating a “public nuisance” through their emissions of climate-warming greenhouse gases.

The Environmental Protection Agency (EPA) on Tuesday issued a final rule that will require—for the first time—most large emitters of greenhouse gases to begin recording data under a new reporting system starting in 2010.

The week brought several developments concerning climate change legislation. A Republican senator is considering introducing an amendment to a fiscal appropriations bill that would prevent the Environmental Protection Agency (EPA) from regulating greenhouse gas emissions from stationary sources. Meanwhile, as reports emerged that Senate hearings on climate change legislation could begin next month, Texas Governor Rick Perry railed against the Waxman-Markey bill, and China pledged to slow growth of its carbon emissions.

Working Mother magazine has selected American Electric Power (AEP) as one of the 100 best companies for working mothers. AEP is the only electric utility and the only Ohio-based company on the 2009 list.

Southern Co. plans to implement an advanced integrated gasification combined-cycle (IGCC) technology developed in conjunction with the Energy Department, KBR Inc., and other partners at an Alabama federal research facility at an existing fuel oil–fired power plant in China, the company said on Thursday.

The Department of Energy last week announced the award of 11 projects worth $75.5 million to conduct site characterization of promising geologic formations for carbon dioxide storage.

Babcock International last week agreed to buy the full commercial arm of the UK Atomic Energy Authority (UKAEA)—a UK government body that provides nuclear decommissioning, waste management, and new nuclear build support services—for £50 million.

By Kennedy Maize A few environmental myths about electric power just won’t die. I’ll begin to discuss some of them in this blog. The first is that exposure to electrical and magnetic fields from high-voltage power lines causes cancer. This long-shot-down claim resurfaces repeatedly. It is simply wrong, and multiple scientific studies – including a […]

By Kennedy Maize This blog has nothing to do with energy or power.  It’s about music. But I suspect that there are enough readers out there who will connect with it to make the blog worthwhile. I’m writing about the death on Sept. 16 of Mary Travers, 72, the dominant force of the folk group […]

By Kennedy Maize Partisan Correctness: Does Harry Reid Speak for Harry Reid? Who’s speaking approximate truth here? Senate Majority Leader Harry Reid (D-Nev.) said this week in a press conference that he expects energy and climate legislation, which has narrowly passed the House, will get punted into next year. The reason, Reid said, is the […]

California Gov. Arnold Schwarzenegger (R) signed an executive order on Tuesday directing the California Air Resources Board (CARB) to adopt regulations by July 31, 2010, to increase California’s Renewable Portfolio Standard (RPS) to 33% by 2020—one of the strictest in the country.

GE-Hitachi (GEH) Nuclear Energy last week said it had submitted a final design certification document for the Economic Simplified Boiling Water Reactor (ESBWR) to the Nuclear Regulatory Commission (NRC). The submittal allows the regulatory agency to proceed with its evaluation of the third-generation reactor design.

An innovative project that uses algae to mitigate carbon emissions from a coal-fired power plant owned by Arizona Public Service (APS) has received a $70.5 million grant from the Department of Energy (DOE).
