This month in POWER (OCTOBER)

October 1886 In the late 19th century, efficient combustion of solid fuels was achieved more by trial and error than by a fundamental understanding of stoichiometry and staged combustion. Boiler manufacturers took many different approaches to the challenge. Some made sense; others didn’t. In which category does the design described below fall? In 1886 the […]

Tenaska Virginia Generating Station, Scottsville, Virginia

Not every facility that POWER singles out as a Top Plant has a unique design. Some, like this one, may be recognized for an excellent operations record and being a good corporate citizen. At Tenaska Virginia Generating Station, a formal program to make O&M personnel aware of best industry practices—and apply them on the job—has shortened the plant’s start-up time and elevated its availability, making it much more dispatchable and profitable.

Port Westward Generating Plant, Clatskanie, Oregon

Since going commercial this June, Port Westward Generating Plant has taken its rightful place as one of America’s most efficient power stations. It is now helping to satisfy Portland General Electric’s summer demand reliably and cost-effectively. What differentiates Port Westward is its pioneering use in the U.S. of Mitsubishi Heavy Industries’ G1 class combined-cycle combustion turbine.

Port Arthur II Integrated Hydrogen/Cogeneration Facility, Port Arthur, Texas

The rationale for a typical cogeneration plant is clear: Supply some power, and maybe some steam, to an industrial host and save energy dollars on both sides of the fence. But integrating a cogen plant that also produces hydrogen with a major refinery that operates 24/7 is a job best left to a company with diverse and proven technology skills. The Air Products Port Arthur II project proves that such a job can be done right. Accordingly, it is one of POWER’s natural gas–fired Top Plants of 2007.

GTAA Cogeneration Complex, Mississauga, Ontario, Canada

When a blackout shuts down a factory, the impact isn’t apparent to the public. But lose power at an international airport, and thousands of angry travelers and the people waiting for them won’t be interested in excuses. The Greater Toronto Airports Authority learned that lesson in August 2003. Ten months later, it began building a 117-MW cogeneration plant that is now capable of supplying all of its energy needs—not just electricity, but space heating and chilled water as well.

Groton Generating Station, Groton, South Dakota

This plant’s main claim to fame: It marks the commercial debut of GE’s 100-MW LMS100 gas turbine-generator. According to Basin Electric, over the unit’s first year of service it has demonstrated top-notch operating flexibility in peaking, mid-range, and baseload service, thanks to capabilities such as 10-minute cold start-ups and minimal impact on heat rate at partial loads. In addition to hosting the first LMS100, Groton Generating Station earns recognition as one of POWER’s Top Plants for the attention its design pays to reliability and resource planning.
