Dominion Virginia Power on Friday said it had selected Mitsubishi Heavy Industries’ (MHI’s) U.S-specific version of the Advanced Pressurized Water Reactor (US-APWR) for its proposed unit at North Anna Power Station in central Virginia. The selection was the result of a competitive process launched by the utility last year.

Wisconsin’s Public Service Commission (PSC) on Tuesday said it had authorized Wisconsin Power and Light Co. (WPL) to spend $150 million to install additional emissions reduction technology at Edgewater Generating Station Unit 5.

By Kennedy Maize Washington, D.C., May 7, 2010 — The U.S. Environmental Protection Agency never saw a regulation it didn’t like. The Competitive Enterprise Institute never saw one it did. Now the federal agency and the Washington-based conservative think tank are involved in a silly but amusing battle of “Did not! Did so!” It promises […]

By Kennedy Maize Washington, D.C., May 6, 2010 — Gambling appears to be a nearly ubiquitous human trait, as a news release I received recently demonstrates. The release, from Bookmaker.com, an offshore gambling den (online betting is technically illegal in the U.S., but that’s a joke) offers the odds that BP will be able to […]

The U.S. Environmental Protection Agency proposed two landmarks rules this past week: On Friday, it released regulations that seek to govern mercury emissions from some 200,000 industrial boiler process heaters and solid waste incinerators, and on Tuesday, it issued a long-awaited proposal to regulate coal ash—though it deferred a decision on whether to treat it as hazardous waste.

Rules adopted by the California Water Resources Control Board on Tuesday will force 19 coastal power plants—including two nuclear plants—in that state to phase out “once-through cooling” practices to reduce their impact on marine life. The new rules—the first in the U.S. to restrict ocean water use for existing power plants—could have widespread implications, including massive costs and forced shutdowns.

Mississippi Power Co.’s plans to build a 582-MW integrated gasification combined cycle (IGCC) plant proposed in Kemper County could be scrapped after regulators last week ordered a cost recovery cap of $2.4 billion—some $800 million less than what the utility had originally sought.

A Superior Court judge in Georgia on Friday ruled that the state public service commission acted illegally when it certified Georgia Power’s two proposed Plant Vogtle reactors by failing to properly document justification for the reactors.

Progress Energy will postpone major construction activities at its proposed Levy County nuclear plant in Florida until after the project’s federal licensing is complete. The company last week said in a statement announcing its 2011 filing of nuclear cost-recovery estimates that the delay would allow for “greater clarity on federal and state energy policies.

San Diego–based Sempra Energy last week agreed to pay $410 million to settle a series of lawsuits and claims arising from the 2000–2001 California energy crises. The payments will go toward some $3.2 billion in settlements already negotiated by California’s attorney general and California Public Utilities Commission (CPUC) with various energy companies that allegedly profited from artificially inflated power prices during the crisis.

Seven years have passed since the world’s first low mass flux vertical tube once-through furnace was put into operation by Doosan Babcock at the Yaomeng Thermal Power Plant Unit 1 in China. That boiler replaced a boiler of another design that had become unreliable. The operating experience with the Posiflow design has been so positive that the owner has since ordered and commissioned a replacement for Unit 2’s boiler. Here’s what makes this furnace design unique.

Shrinking water supplies will unquestionably constrain the development of future power plants. A hybrid system consisting of concentrated solar thermal power and desalination to produce water for a plant, integrated with a combined cycle or conventional steam plant, may be the simple solution.

In 2006 and 2007, POWER ran a three-part series on the formation of SO₃, O&M issues caused by SO₃, and sorbent injection control for SO₃ control. Three years later, many plants still struggle with their SO ₃ mitigation systems or remain undecided on which mitigation path to follow. This article explores the advantages of dry sorbent injection technology.

Offers of nuclear loan guarantees are pending, construction permit applications are at an industry high, and the political stars seem to be properly aligned. However, there remains one obstacle in the development path of the next-generation of nuclear plants: How will these plants be financed?

Mexico’s federal government retains almost total control over who builds and owns what electricity infrastructure. But if you know how to work within the strict constraints, it is possible to engage in profitable projects.

E Instruments has just released its TH300 humidity and temperature sensor, which is ideal for applications that require a single, high-accuracy instrument. The sensor measures relative and absolute humidity, dew point, wet and dry temperatures, and enthalpy. The range of measurement is from 0% to 100% relative humidity and – 40F to 356F. Accuracy is […]

NAFTA was both good and bad for Mexico. In both cases, it required a different approach to doing business, and the effects of that shift are still playing out.

The Brattle Group released a provocative study paper in March in which the authors postulate that using more natural gas for generating electricity could reduce our dependence on coal-fired generation and reduce carbon emissions. Also discussed is an unexpected side effect: Renewables could push natural gas plants down in the dispatch mix in the future. […]

The demand for "green" electricity — electricity produced from renewable sources like wind, solar, hydropower, geothermal, and biofuels — is at an all-time high in the U.S. Over the past decade, solar and wind capacity have increased dramatically due largely to mandatory renewable portfolio standards (RPS), which have now been adopted by 27 states.

State control of the electricity sector may mean fewer customers, but it also can mean clearer expectations.

Despite the political kerfuffle over Obama administration loan guarantees for new nuclear generating plants, the ubiquitous hand-wringing about fossil fuels and climate change, and the hype about wind and solar renewable power generation, the new reality of natural gas may be a game-changer.

The Brattle Group released a provocative study paper in March in which the authors postulate that using more natural gas for generating electricity could reduce our dependence on coal-fired generation and reduce carbon emissions. Also discussed is an unexpected side effect: Renewables could push natural gas plants down in the dispatch mix in the future. Just because natural gas reserves are at a record high and the price is at historic lows doesn’t mean that gas demand will increase.

Laser shaping technology has evolved from a two-step process into a single process that drills and shapes holes through a TBC, bond coat, and airfoil base metal to create a finished product.

The fear of losing electric power inspires thoughts about how vital electricity is to our lives. It is fundamental to modern living, and that’s entirely a good thing.

For the past 26 years, Cambridge Energy Research Associates (CERA) has hosted an annual CERAWeek conference in Houston that is renowned for high-profile attendees from around the world. During the week of March 8, security was tight as oil ministers from the Middle East and CEOs from the largest oil and gas companies and electric utilities rolled into Houston to exchange ideas and forecasts. More than 1,200 delegates from 55 countries attended to hear more than 100 distinguished speakers discuss a business that seems to have renewed optimism about the future.

Extech Instruments introduced the EX845, a 1,000A AC/DC CAT IV clamp meter with new METERLiNK technology and a built-in infrared thermometer. METERLiNK wirelessly connects FLIR infrared cameras to Extech meters via Bluetooth to simplify inspections. During infrared inspections of electrical components, users can transmit key electrical readings such as current or voltage from an Extech […]

Wind power’s cost is hidden in subsidies; its value is overstated and based on false metrics that don’t account for reliability and dispatchability.

This third and final installment addresses three more areas where an investment in good maintenance practices pays operating availability dividends.

Flowserve Corp. has added 24- to 48-volt DC-input power for all sizes of Flowserve Limitorque QX electronic valve actuators. The QX offers reliability for remote applications that require an uninterrupted power supply but cannot use single- or three-phase AC volts. The electronic controls in the Limitorque QX actuators with DC volt capability are 100% digital […]

Some amount of NIMBYism should be expected when developing any new project. Good planning and actively engaging community leaders early and often will increase your success quotient.
