The MGV24-1200 can be used with any dump-style lance, and the lances can […]

On Feb. 22, 2013, the U.S. Environmental Protection Agency (EPA) proposed a rule, 78 Fed. Reg. 12459, that will require 36 states to eliminate an exemption to Clean Air Act (CAA) emission requirements for exceedances that occur during periods of startup, shutdown, or malfunction (SSM).

The Wall Street Journal ( WSJ) recently reported that 14 of the 29 states that have adopted a renewable procurement mandate are currently considering legislation that would “water down or repeal” the renewable set-aside. Proponents of repeal describe their motivation as simple economics: Renewable power increases costs to electric consumers.

The LM6000 is the most widely used aeroderivative combustion turbine (CT) in the world, with more than 1,000 installations. As with all CTs, power output and heat rate degrade markedly during warm weather. The ARCTIC (Absorption Refrigeration Cycle Turbine Inlet Conditioning) system eliminates this deficiency.

Modern heat recovery steam generator (HRSG) design must balance operating response with the reduction in life of components caused by daily cycling and fast starts. Advanced modeling techniques demonstrate HRSG startup ramp rates can be accelerated without compromising equipment life.

URS recently performed a combined cycle repowering study to determine the feasibility and economics of repowering an existing steam turbine that went into service in the 1950s. The competing option was building a new combined cycle unit. The results of the study provide insight for others considering the same alternatives.

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience has shown that the majority of control loops can perform better—provided that the root cause of the poor performance is found and corrected.

Lawrence J. Makovich, PhD, IHS CERA’s vice president and senior advisor for Global Power, predicts a rebound in electricity consumption from recession levels. Specifically, the rebound will be stronger than government projections, led by growth in electricity use by industry.

Have you ever experienced a restaurant menu overflowing with so many tasty entrées that making your selection seemed an impossible decision? Your deliberation probably ended when the waiter began tapping a pen on his order pad and your dinner-mates gave you the evil eye. Picking a commentary topic each month is much like scanning the dinner menu. There are usually many topics that deserve a good slice and dice, but it’s the deadline that forces a decision.

New England’s big push toward gas-fired power collided hard with its historical pipeline constraints this past winter, leaving multiple generators unable to respond to start-up requests from ISO-New England during a major storm. In the wake of the episode, the region is looking for some long-term solutions.

MidAmerican Energy Holdings Co., a unit of Berkshire Hathaway Inc., is buying NV Energy Inc. for $23.75 a share in cash, or around $5.6 billion. The companies said the deal was unanimously approved by both boards of directors and could be completed in the first quarter of 2014, pending shareholder approval as well as approval by state and federal regulators.

The D.C. Circuit Court on Tuesday dismissed an appeal by Sunflower Electric Power Corp. of a ruling requiring environmental review of Sunflower’s proposed 875-MW coal-fired power plant in Holcomb, Kansas.

Sen. Barbara Boxer (D-Calif.) on Tuesday called for a federal investigation to determine whether Southern California Edison (SCE) intentionally misled regulators regarding the installation of faulty steam generators at the beleaguered San Onofre Nuclear Generating Station.

A carbon tax or cap-and-trade programs could raise trillions of dollars within the first 10 years of their enactment and avert climate change effects, but without accounting for how these revenues will be used, they could take a toll on the U.S. economy, the Congressional Budget Office (CBO) says in a report released on Tuesday.

Panelists at a House hearing on Tuesday held to examine steps the federal government and private sector are taking to bolster the nation’s critical infrastructure security shed light on the extent and variety of possible cyberattacks and called for flexible solutions. The hearing was held days after the National Institute of Standards and Technology (NIST) released its initial analysis of hundreds of comments submitted in response to President Obama’s February 2013 cybersecurity executive order.

A final rule issued by the Federal Energy Regulatory Commission (FERC) on Thursday orders the North American Electric Reliability Corp. (NERC) to develop, by the end of the year, reliability standards that address the impact of geomagnetic disturbances (GMD) on the nation’s bulk power system. Those standards will likely require generators and grid operators to develop and implement operational procedures and conduct continuing assessments on equipment to mitigate GMD effects.

The North American Electric Reliability Corp. (NERC), in a special reliability assessment released on Wednesday, called for a number of changes to address the increased reliance on natural gas for power generation, among them incorporating gas availability and gas supply issues into electric reliability assessments.

Freeport LNG Expansion LP and FLNG Liquefaction LLC received conditional authorization on May 17 to export U.S. liquefied natural gas (LNG) from the Freeport LNG Terminal on Quintana Island, Texas, making it the second project to receive federal approval. Meanwhile, Canada is considering a proposed LNG export terminal in British Columbia.

A promising new approach to securing communications networks from cyber crime uses quantum cryptography. Researchers at Los Alamos National Laboratory (LANL) have developed a system that could be used for critical infrastructure control systems, including those at power plants.

An updated fracking rule proposed by the U.S. Department of the Interior’s Bureau of Land Management (BLM) last week maintains a number of requirements from a previous draft—including that well operators should disclose all chemicals used in fracturing activities on public lands—but it will improve integration with state and tribal standards and increase compliance flexibility, the agency said.

The full Senate last week confirmed Ernest Moniz as Energy Secretary while a divided Senate Committee on Environment and Public Works (EPW) voted 10–8 to send the nomination of Gina McCarthy as administrator of the Environmental Protection Agency (EPA) to the full Senate for a confirmation vote. Republicans agreed to lift their boycott on the McCarthy vote only after the EPA agreed to meet a number of transparency commitments.
