  • Firstenergy to Convert Coal-Fired Burger Plant to Biomass

    Confronted with a district court ultimatum that would have forced it to install expensive pollution controls or close two coal-fired units at its R.E. Burger Plant in Shadyside, Ohio, Akron-based FirstEnergy Corp. announced in April that it would convert them to biomass. When the $200 million retrofit is complete, as is expected by 2013, the Burger Plant will likely be one of the largest biomass facilities in the U.S.

  • Powering the People: India’s Capacity Expansion Plans

    India has become a global business power even though hundreds of millions of its citizens still live in poverty. To sustain economic growth and lift its people out of poverty, India needs more — and more reliable — power. Details of government plans for achieving those goals demonstrate that pragmatism may be in shorter supply than ambition and political will.

  • Interest in Solar Tower Technology Rising

    Though solar thermal tower technology has been around since the 1970s, to date, only one plant in the world commercially generates electricity: Abengoa Solar’s 11-MW PS10 tower just outside Seville, in Spain’s Andalucía desert has been grid-connected since early 2007. Because the technology relies on heat from solar energy that is reflected by mirror arrays (heliostats) onto a tower-mounted receiver, installations tend to be site-specific, expensive, and high-maintenance.

  • The Foreign Investment Factor (supplement to Powering the People: India’s Capacity Expansion Plans)

    Recognizing that the long-term sunk cost, long project planning and construction timeframe, and high-risk portfolio make it difficult for private investors to raise funds whose maturity matches project completion dates, the Indian government has since 1991 allowed 100% foreign direct investment in the power sector.

  • Boiler-Tuning Basics, Part II

    Boilers have enormous thermal mass and are relatively slow to react. Turbines are nimble and quickly answer an operator’s command. Coordinating an entire plant requires an intimate knowledge of both systems and selecting the right logic tools to bring them together.

  • Tidal Barrages Could Power 5% of UK

    Barrages across the Solway Firth, Morecambe Bay, and the Mersey and Dee estuaries in the northwest UK could provide more than 5% of the nation’s electricity and meet half the region’s electricity, a study by engineers at the University of Liverpool has found.

  • Nuclear Uprates Add Critical Capacity

    New-generation nuclear plants may be having trouble getting out of the gate, but that doesn’t mean that nuclear capacity additions are at a standstill. In fact, the 104 operating nuclear units in the U.S. have added substantial new capacity in the form of reactor and plant uprates over the past 20 years. Power uprates alone have added more than 5,600 MW since 1998 — the equivalent of five new nuclear plants.

  • Geologists Map Carbon-Trapping Rock Formations

    U.S. scientists concerned about carbon dioxide (CO2) leaks from sequestration attempts have been pursuing the option of natural chemical reactions within the earth to turn the carbon back into a solid, and they have identified an abundant supply of large rock formations around the world that could be used a vast sink for the heat-trapping gas.

  • Birth Pangs of the Nuclear Renaissance

    The much-ballyhooed U.S. nuclear renaissance, with a few exceptions, is running late, thanks to the usual Washington bureaucratic quagmire plus the added risk resulting from crumbling financial markets. The future doesn’t look much brighter. The poor outlook for Yucca Mountain and the new administration’s general indifference to nuclear power have made a rebirth of the nuclear industry an even higher-risk proposition than before.

  • Tapping Geothermal Energy with a Comprehensive Strategy

    Geothermal energy in Europe may have been used for centuries — it was popularized by the Romans and adopted by the Turks — but geothermal-generated electricity was first produced at Larderello, Italy, in 1904. Since then, its growth on the continent has shot up to 820 MW. But, according to the European Renewable Energy Council, the resource’s full potential has barely been harnessed.

  • Renewable Project Finance Options: ITC, PTC, or Cash Grant?

    Dozens of institutional investors in U.S. renewable energy projects pulled out of the market when the nation’s liquidity reserves dried up late last year. Some left the renewable market sector in search of more lucrative investment opportunities. Others found themselves unable to take advantage of the attractive tax credits because they themselves lacked profits against which to use the credits. The American Recovery and Reinvestment Act of 2009, approved February 13, changed the investor ground rules — again.

  • Switchgear Technology Surpasses 1 Million Volts

    Swiss power technology group ABB, which pioneered gas-insulated switchgear 50 years ago, in April announced it had commissioned switchgear rated to handle 1,100 kV. The development marks the biggest leap in capacity and efficiency of AC power transmission in more than two decades.

  • Two-Pump Fuel Recirculating System

    The Duplex Pump Unit (FRS 660-11-DPU-UL) from RCI Technologies is the newest addition to that company’s line of diesel fuel purifiers and fuel recirculating systems (FRSs). Designed to automatically circulate and clean the fuel in customers’ fuel storage tanks on a preprogrammed schedule, the DPU features two fuel pumps, which operate alternately to circulate fuel through the system. Whereas RCI’s other FRS units utilize a single pump, the duplex pump offers backup in the event of a primary system failure. All FRS units employ filter-less technology. The control system is housed in a weatherproof, NEMA 4, key-lockable cabinet, and the system is equipped with alarms to alert the user in the event of pump failure, purifier high water level, system high pressure, or fuel catch basin leak.

  • Gas Hydrates: Fuel of the Future?

    Gas hydrates, a form of natural gas that forms when methane from the decomposition of organic material comes into contact with water at low temperatures and high pressures, could play a role — even if a small one — in future fuel supplies, researchers attending a March meeting organized by the American Chemical Society suggested.

  • Energy Bubble, Anyone?

    When the housing bubble burst, it exposed an unseemly alliance between special interests and the financial sector. Activists wanted homes for all at any cost, and lenders were happy to oblige despite the inherent risk.

  • Extreme Temperature Vibrating Fork

    Emerson Process Management launched a new extreme temperature version of its Rosemount 2130 vibrating fork liquid level switch that is designed for use in extreme temperatures — from – 94F to 500F (–70C to 260C). The new version includes a low-density option suitable for liquids with specific gravity down to 0.5 (500 kg/m 3). In addition to built-in fault-monitoring/self-checking diagnostics to detect corrosion of the forks or any internal or external damage or breaks in the internal electrical wiring, it features a "heartbeat" LED, which provides instant visual indication that the unit is operational. The unit requires no onsite calibration and is available in 316L stainless steel, corrosion-resistant alloy C wet side, or a range of other stainless steel and aluminum options.

  • FERC’s Wellinghoff bloviates on wind

    Jon Wellinghof, the latest chairman of the Federal Energy Regulatory Commission, is, by his own words, a doofus. As reported in Power News this week, Wellinghoff said the U.S. may never need new baseload electric generating capacity.  Why? Because wind will be so cheap it will get sent out first in an economic dispatch regime. […]

  • Bill to Rebate Utilities Billions from Yucca Mountain Waste Fund

    The estimated $30 billion that electric utilities have paid since 1982 to the Nuclear Waste Trust Fund for the construction and operation of the federal nuclear waste repository at Yucca Mountain could be returned to them if a Senate bill introduced on Thursday passes.

  • FERC Chief: U.S. May Never Need New Nuclear, Coal

    The U.S. may never need new nuclear or coal-fired power plants because renewable energy and improved efficiency can meet future power demand, Jon Wellinghoff, the Federal Energy Regulatory Commission chair, last week reportedly said.

  • UK Energy Secretary: No New Coal Plants Without CCS

    The UK will not permit new coal-fired power plants without equipment to capture and store at least 25% of carbon emissions from day one and 100% by 2025, when carbon capture and storage (CCS) technology is expected to be technically and commercially proven, the country’s climate change secretary, Ed Miliband, said last week.

  • AmerenUE Suspends Missouri EPR Project for Financial and Regulatory Reasons

    Changes to a state bill that would have allowed AmerenUE to charge customers during the construction of a second nuclear plant at Callaway in Missouri last week prompted the company to pull the plug on the $6 billion project.

  • Utility Execs Foresee Higher Power Prices, More Regulation with Obama Initiatives

    Executives of North American utility companies are nearly split on whether President Obama’s proposed energy initiatives will have a significant impact on the structure of the electricity sector, according to the third annual Platts/Capgemini Utilities Executive Study just released. But there is greater executive agreement that environmental regulation and electricity prices for end users will be increasing.

  • NYPA Calls for Offshore Wind Projects in Great Lakes

    Spurred by New York’s target to meet 45% of its electricity needs through renewable resources by 2015, the New York Power Authority (NYPA) last week issued a call for proposals to develop offshore wind projects of up to 120 MW in New York State waters of Lake Erie and Lake Ontario.

  • NERC: Misoperation of System Protection and Control Systems Leading Cause of Bulk Power Disturbances

    The performance of automated systems designed to protect infrastructure from damage during severe system conditions must be addressed to limit the scope and severity of bulk power system disturbances in North America, the North American Electric Reliability Corp. (NERC) told stakeholders in a letter last week.

  • EPA Motions to Reconsider Granted Coal Plant Permit

    The Environmental Protection Agency (EPA) wants to reconsider an air permit it awarded last July to the 1,500-MW coal-fired Desert Rock Energy Facility project proposed for construction by Sithe Global Power, LLC on the Navajo Nation tribal reservation in New Mexico.

  • Remembering Three Mile Island

    The 30-year anniversary of the Three Mile Island accident passed with little fanfare because our nuclear plant fleet today operates with high reliability and struts an excellent safety record. That wasn’t always the case.

  • Nuclear Loan Guarantees Have Failed

    Nuclear loan guarantees in the 2005 Energy Policy Act have proven to be a failure: not just too little, but far too late.

  • Let’s Trash Employee Performance Reviews

    UCLA management guru Sam Culbert calls annual employee performance reviews “bogus” and not conducive to good company management. Get rid of them, he says.

  • The Supply Chain and the Carbon Footprint

    Few companies consider carbon in their supply chain decisions, says an Accenture study. Should purchasers require carbon reductions from suppliers as part of their business model?
