The power industry’s operating and maintenance practices were held up to intense regulator and public scrutiny when on November 6, 2007, a Massachusetts power plant’s steam-generating boiler exploded and three men died.

Chromium-molybdenum (chrome-moly) pipe has become a standard in the power generation industry, not only because of its corrosion resistance and high-temperature strength, but also for its cost-effectiveness. In many applications, it is a viable alternative to a more costly stainless steel pipe.

In a bid to preserve some of the health and air quality benefits of a defunct regulation, House Democrats have floated a legislative proposal to codify the near-term emission reductions required under the Bush administration’s Clean Air Interstate Rule, a regional cap-and-trade program for utility emissions that was thrown out in July by a federal appeals court.

Spurred on by a recent audit showing widespread utility noncompliance with voluntary recommendations meant to protect the grid from cyber attacks, key lawmakers have unveiled plans to give the Federal Energy Regulatory Commission (FERC) broad powers to enact new mandatory measures to close vulnerabilities in the U.S. bulk power system to potentially devastating computer-launched assaults.

In a move that could boost the value of wind and nuclear generation, relieve stress on the nation’s transmission grid, and reduce utility carbon emissions, PSEG Global LLC and energy storage pioneer Michael Nakhamkin have announced that they have formed a joint venture to market and deploy “second generation” compressed air energy storage technology.

No matter what its size, fine particulate matter is a serious matter for coal-burning power plants. A process that charges those particles shows promise for mitigating the problem.

Wisconsin Public Service Corp. placed its world-class Weston 4 into commercial service on June 30 and is now enjoying the benefits of coal-fired supercritical technology’s inherently higher efficiency, operating flexibility, and lower CO2 emissions. For its unequalled environmental protection credentials, well-integrated project team, and employing without a doubt the most advanced coal-fired steam generation technology in the U.S. today, Weston 4 is awarded POWER magazine’s 2008 Plant of the Year award.

Lamar Light and Power is a municipal utility that has been generating the southeastern Colorado city’s electricity since 1920. Rising natural gas and oil costs pushed LL&P to retire its steam plant five years ago and begin hunting for more economic power sources. The answer: repower the existing plant with a state-of-the-art coal-fired circulating fluidized-bed combustor and cross-connect old and new steam turbines. The $120 million project will stabilize the region’s electricity rates for many years to come and is the winner of POWER’s 2008 Marmaduke Award for excellence in O&M—named for Marmaduke Surfaceblow, the fictional marine engineer/plant troubleshooter par excellence.

British Columbia began collecting increased tax revenue on fossil fuels on July 1 with a promise to rebate those taxes through reduced income and business tax rates. This "revenue recycling" plan makes little progress toward the province’s goal to reduce CO2 emissions 33% by 2020, yet it is hailed by proponents as a legislative milestone. Others believe B.C. residents are victims of another governmental "bait and switch" program. Does it matter to the rest of the world?
