As part of constructing the recently commissioned We Energies’ Oak Creek Power Plant Elm Road units, four remarkable below-ground structures were built. Each unique structure required creative designs and meticulous construction techniques to meet the project’s distinctive requirements.

It has been three years and a few months since the North American Electric Reliability Council (NERC) Reliability Standards (Standards) became mandatory and noncompliance became subject to sanctions by the Federal Energy Regulatory Commission (FERC). You might assume that because we have had no further instances of widespread cascading outages that the Standards are working. You may also assume that—considering the database of documented noncompliance with the Standards—the industry as a whole is puzzled, unprepared, or negligent in carrying out its responsibility to keep the high-voltage electric grids reliable and secure. The truth likely lies somewhere in the middle.

Environmentalists renewed their attacks on coal-fired power development in 2010. At the same time, Congress dithered on cap-and-trade legislation while the Environmental Protection Agency marched forward rules to reduce carbon emissions from coal-fired power plants. Couple the regulatory uncertainty with lean economic times that have flatlined electricity demand growth plus low natural gas prices, and the result is predictable: New coal-fired plant construction is in the doldrums.

The National Institute of Standards and Technology (NIST) has finalized its initial set of smart grid cyber security guidelines. NIST’s Guidelines for Smart Grid Cyber Security (NISTIR 7628) includes high-level security requirements, a framework for assessing risks, an evaluation of privacy issues in personal residences, and other information for organizations to use as they craft strategies to protect the modernizing power grid from attacks, malicious code, cascading errors, and other threats, according to NIST’s press release.

The age-old adage “water and electricity don’t mix” does not apply to 21st-century infrastructure planning. The two entities can no longer be viewed as separate commodities. The demands on both are intertwined, so solutions for meeting new and growing challenges associated with water scarcity and carbon regulations must also be integrated. Water is essential to […]

Cleaning air heaters in power plants or recovery boilers has traditionally involved using high-pressure water, chemicals, or steam. These techniques, though effective on moderate airside fouling of heat exchange surfaces, are usually ineffective on the more tenacious deposits that can develop in coal-fired plants. If these deposits are not removed by periodic cleaning, heat transfer in the heaters is reduced, which in turn reduces boiler efficiency and increases a unit’s heat rate. Severe fouling on air preheaters (APHs) can even reduce a unit’s power output.

Sierra Instruments has introduced a new cryogenic version of its Innova-Mass multivariable mass vortex flow meter for measuring mass flow rates of cryogenic fluids down to –328F (–200C). Using a special cryogenic temperature RTD, mass calculations are done with the latest density equations of state for liquid oxygen, nitrogen, argon, and carbon dioxide. The multivariable […]

Many power purchase agreements entered into between qualifying facilities (QF) and electric utilities during the 1980s and 1990s have several years remaining on their terms. These contracts typically require the generator to comply with the Federal Energy Regulatory Commission (FERC) regulations promulgated pursuant to the Public Utility Regulatory Policies Act (PURPA). The foremost FERC requirement […]

The new IntelliPULSE pulse jet timer for baghouses and dust collectors from FilterSense reduces energy costs and offers direct connection to programmable logic controllers with user-specified fieldbus communications such as Devicenet, Ethernet, Modbus, and Profibus. The intelligent pulse-cleaning control technology is said to minimize compressed air use during filter cleaning, significantly reducing energy consumption. No […]

In the heart of corn country, Archer Daniels Midland is using seed corn that is no longer suitable for planting, along with coal, to power its 180-MW Clinton cogeneration plant. The cogeneration plant, which began operations in 2008, supports ADM’s Clinton corn processing plant, one of the largest corn wet mills in the world. It also supports ADM’s facility that produces renewable plastic from corn sugar. Firing up to 20% biomass along with coal, the new cogeneration plant is capable of providing 100% of the steam and electrical power needs of both facilities.

Power plant operators must keep the corrosion, deposition, and microbiological fouling affecting cooling water systems at bay to avoid damage to equipment and system inefficiencies. One possible solution is GE’s newly released TrueSense, a technology platform that enables users to monitor and control cooling water systems. TrueSense integrates three functionalities into one platform: online monitoring […]

By Kennedy Maize Washington, D.C., Sept. 29, 2010 – I love Alaska. The beauty of the mountain ranges, rivers, islands, and glaciers is stunning. The diversity of habitat and wildlife inspires wonder. The summer days and winter nights are filled with mystery. The people, of all ethnicities and political persuasions, are endearing and quirky. My […]

Computers at Iran’s Bushehr nuclear reactor and around the country have reportedly been infected by the Stuxnet worm, a sophisticated malware that attacks supervisory control and data acquisition (SCADA) systems at power plants, factories, and military installations.

Electric grid cybersecurity in the U.S. was revved up in the past week as the Energy Department announced investments of more than $30 million in 10 solution-seeking projects. At the same time, the DOE selected an Electric Power Research Institute- (EPRI-) led collaborative to assess and develop technologies and standards to protect the nation against cyber attacks.

Regulators at the California Air Resources Board (CARB) unanimously voted to increase that state’s renewable electricity standard (RES) to 33% by 2020 last week. The regulation applies to all entities that deliver power, including publicly owned utilities and investor-owned utilities.

The California Energy Commission (CEC) last week approved BrightSource Energy’s 370-MW Ivanpah Solar Electric Generating System proposed for construction in the Mojave Desert. The project is the fourth solar thermal power plant approved in the past month despite presenting “significant environmental challenges,” the commission said.

American Electric Power and Allegheny Energy last week said they filed a new application with the Virginia State Corporation Commission (SCC) to build the Virginia segment of the Potomac-Appalachian Transmission Highline (PATH).

A wave energy device was connected to the grid for the first time in the U.S. this week. Ocean Power Technologies (OPT) hooked up its PowerBuoy system, a device that had been deployed in December 2009 in waters 100 feet deep and nearly three-quarters of a mile off the coast of Oahu, Hawaii.

The Energy Department on Tuesday said it had signed a final cooperative agreement with the FutureGen Industrial Alliance and Ameren Energy Resources, formally committing $1 billion in Recovery Act funding to build the revamped FutureGen project.

Costs passed onto consumers associated with the construction of Duke Energy Indiana’s Edwardsport coal gasification plant near Vincennes, Ind., will be capped at $2.975 billion, according to a settlement agreement reached last week between the utility, the Indiana Office of the Utility Consumer Counselor (OUCC), and Nucor Steel Indiana.

The California Energy Commission (CEC) last week unanimously approved construction and operation of Solar Millennium’s 1,000-MW Blythe Solar Power Project. If built, the project, consisting of four parabolic trough units, could be the world’s largest concentrating solar power (CSP) facility and among the first commercial solar thermal plants permitted on federal land.

Xcel Energy shut down its 538-MW Black Dog Power Plant in Burnsville, Minn., on Tuesday after an explosion rocked the coal- and gas–fired plant, causing visible damage to the exterior of the building. No personnel were harmed, but three firefighters responding to a smoldering fire in a coal hopper received minor injuries, police said.

Whether you are a customer (and we all are), a utility executive, a power plant manager, or a grid operator, the smart grid has the potential to provide benefits beyond electricity. That was one theme of the presentations on Tuesday, the first day of the GridWise Global Forum (GGF) in Washington, D.C.

South Africa’s government on Thursday announced it would no longer invest in the Pebble Bed Modular Reactor (PBMR) project, despite providing nearly 80% of the R9.2 billion ($1.3 billion) that has been poured into development of the Generation-IV helium-cooled high temperature reactor design. The decision was reached with the “fiscal constraints in these hard economic times” in mind, the government said.

The week brought important news from Washington on energy- and climate change–related legislation. Sens. Jeff Bingaman (D-N.M.) and Tom Udall (D-N.M.) introduced a bill to create a federal renewable electricity standard, the White House said it had received permitting guidance on greenhouse gases from the Environmental Protection Agency, and Sen. Tom Carper (D-Del.) reportedly canceled a key vote on a bill that sought to curb power plant emissions.

A new study from the Massachusetts Institute of Technology’s Energy Initiative (MITEI) concludes that uranium supplies will not limit growth of the nuclear industry, contrary to a view that has prevailed for decades.

By Kennedy Maize Let us hope that the false hope of fast breeder reactors fueled with plutonium reprocessed from spent light water reactor fuel is finally properly interred. A new report from the same MIT crew that examined the future of nuclear power in 2003 buries the pipe dream of breeder reactors, or, at least, […]

Disputes concerning dominance of the world’s renewable energy sector heated up in the past week: The U.S.-based United Steelworkers (USW) filed a trade case alleging that “illegal” Chinese policies and practices threatened America’s industries, while Japan complained to the World Trade Organization (WTO) that Ontario’s feed-in-tariff (FIT) program violated rules and is protectionist.

Old Dominion Electric Cooperative (ODEC) last week said it would delay plans to obtain air permits necessary to begin construction of its proposed coal-fired Cypress Creek Power Station in southeastern Virginia, citing a slump in demand growth caused by the slackened economy.
