Low Gas Prices Prompt Duke to Retire Coal Units Two Years Early
Citing low natural gas prices, Duke Energy announced on Feb. 1 that it would shutter its 1920s-built Buck and Riverbend stations two years before the coal-fired plants were slated for retirement. The company had chosen to retire the plants just before April 2015, which is the compliance deadline for recently enacted federal environmental rules.

Secretary Chu Announces Departure from DOE
Energy Secretary Steven Chu ended weeks of speculation by announcing that he will not serve a second term in the Obama administration. In his Feb. 1 announcement, Chu said, “In the short term, I plan to stay on as Secretary past the ARPA-E Summit at the end of February. I may stay beyond that time so that I can leave the Department in the hands of the new Secretary.”

Report Calls for Regulation of Emissions from New Power Plants
New analysis by the World Resources Institute (WRI) finds that the U.S. is not on track to reach its goal of reducing greenhouse gas (GHG) emissions by 17% by 2020 (below 2005 levels) but that it has the tools to get there. Specifically, the report looks at steps the Obama Administration and states can take without congressional action. Those steps would, not surprisingly, require emissions reductions from existing power plants and natural gas systems.

How Overcycling Induces Economizer Tube Failures
Why do some HRSG economizers and feedwater preheaters seem to suffer tube failures more frequently than others? If frequent failure is your problem, the cause may not necessarily be your heat exchanger’s design or how often you cycle your plant. Don’t forget to carefully check your feedwater controls—they may be cycling more than your HRSG.

With Fresh Election, Japan Veers Away from Nuclear Phase-Out
A landslide victory handed by Japanese voters to the Liberal Democratic Party (LDP) in mid-December saw power in the country’s Lower House shift back to the nationalist-conservative party that had governed Japan almost continuously since 1955. The LDP had been ousted in a historic defeat only three years earlier. In his first televised interview since taking office, newly elected Prime Minister Shinzo Abe (who previously served as prime minister from September 2006 to September 2007) called for review of plans to phase out nuclear power in Japan by 2030, endorsing instead the construction of new, safer nuclear power plants.

The Shale Gas Revolution Continues
The electricity industry is being transformed by the so-called “shale gas revolution” in the United States. Production of natural gas from shale rock using hydraulic fracturing (“fracking”) has boosted supply and reduced prices, making gas-fired power competitive with coal-fired power on price. Historically, coal-fired electricity generation has dwarfed generation from gas-fired plants in the U.S. […]

Drum Level Instrumentation Update
Accurate knowledge of the water level in any boiler drum application is an absolute necessity. While operating a boiler with low water level is one of the leading causes of boiler failure, operating with a high water level may produce less-than-optimal steam, as well as damage to the steam turbine by moisture carryover.

Coordinated Feedwater Heater Energy Control
The increased use of intermittent renewable energy sources and the shift to gas-fired combustion turbines places new burdens on the dispatch of many coal-fired units. Steam units must now operate at very low minimum load while maintaining the ability to ramp up and down quickly. High-pressure feedwater heater energy control can improve the system response of such coal-fired units.
