U.S. energy infrastructure needs not just substantial investment for […]

The Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP) is feasible in its ultimate goals, but getting there will take a lot of work and some rethinking of how the targets are achieved

Steam production is strongly influenced by the cleanliness of the gas-side heat transfer surface in a heat recovery steam generator (HRSG). However, when deposits begin to impede heat transfer or increase gas-side pressure drop, it is time for a cleaning. CO2 pellet blasting is a cost-effective and environmentally benign cleaning method available to power plant […]

Duke Energy, the largest electric utility in the U.S. in terms of market value, is transitioning its generating fleet away from volatile and sometimes unprofitable wholesale markets and toward the traditional, regulated, cost-of-service model that prevails in much of the Carolinas and Florida service territories where Duke dominates. Late last March, the Federal Energy Regulatory […]

Workers at San Diego’s General Atomics (GA) on April 10 began the years-long process of winding the 1,000-ton superconducting electromagnet that will power the ITER fusion reactor under construction in southern France. The $16 billion ITER project, a consortium of the U.S., the European Union, Russia, China, Japan, and other nations, aims to test reactor-scale […]

No one can accuse the officials who oversee California’s energy market of lacking ambition. Fresh on the heels of Gov. Jerry Brown’s January promise to raise the state’s renewable generation target from 33% in 2020 to 50% in 2030, the California Independent System Operator (CAISO) in April announced that it and Oregon utility and Berkshire […]

From Sweden to China, the world’s nuclear sector saw an eventful spring. Sweden to Shutter Two Ringhals Units Early. On the same day that E.ON—formerly one of Europe’s most formidable power companies—announced it would spin off its nuclear assets owing to Germany’s energy transition, its Swedish partner, Vattenfall, which is 70% co-owner of the 1975-built […]

I’m sure readers of this magazine have noticed the increased emphasis in the U.S. recently on promoting STEM (science, technology, engineering, and math) education. That’s a good thing, but it’s not enough. To improve the odds of achieving the goals that STEM promoters have—including a better-trained workforce and economic leadership—we should be adding an “A” […]

On April 27, the U.S. saw yet another significant milestone for its so-far nonexistent offshore wind sector as Deepwater Wind broke ground on the Block Island Wind Farm in Rhode Island. The company says that the five-turbine 30-MW wind farm will produce enough electricity to power all of the island’s homes and businesses when it […]

Our country’s energy landscape is rapidly changing. For the first time in decades we’re producing more barrels of oil in the United States than we import from other countries, thanks in part to shale oil production. Newly developed natural gas resources have enabled the U.S. to begin transitioning from a modest net importer of natural […]

The installation of more than one million solar photovoltaic (PV) modules at Sempra U.S. Gas and Power’s and Consolidated Edison Development’s 250-MW AC Copper Mountain Solar 3 project in Boulder City, Nev., was completed in early April.

This summer, the Environmental Protection Agency (EPA) will finalize its Clean Power Plan under Section 111(d) of the Clean Air Act, requiring existing fossil fuel–fired electric generating units (EGUs) to cut carbon dioxide emissions to 30% below 2005 levels by 2030. The rule will require states to meet specific reduction goals and also allow states […]

Falling prices and technological improvements have brought battery storage systems into direct competition with traditional distributed generation, demand response, and peaking generation resources. But making one work efficiently and profitably is not just plug and play.   Last fall, Southern California Edison (SCE) had some big decisions to make. The giant utility, which serves 14 […]

Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase. The U.S. utility industry is […]

As I write this column at the beginning of spring, I have two kinds of spring fever: excitement about warming temperatures that bring spring flowers and the “hay fever” caused by tree pollens. I have mixed feelings about spring. I mention this only because the power industry is experiencing a spring fever of its own. […]

The digital economy has changed the way we shop for clothing, travel, communicate with friends and family, consume news, and watch television—among so many other things.
