GE Launches 9.5-MW Engine for Distributed Generation

A 9.5-MW gas engine unveiled by GE this October for decentralized, independent power producers in remote, hot, or high-altitude regions features a 48.7% electrical efficiency and promises to reduce lifecycle costs by lowering fuel consumption.

Turkey Opens Record-Breaking Combustion Gas Engine Plant

Turkey, a country that has seen rapid economic growth since the 1980s, largely spurred by a shift in governmental strategy to open up markets and increase private participation, has been actively overhauling its power infrastructure to meet soaring electricity consumption. According to grid operator Turkish Electricity Transmission Co., national consumption increased to 17 billion kWh this September—an 11% increase over the 15.3 billion kWh consumed in September 2009.

Microturbine Technology Matures

Microturbine technology has evolved from early systems of 30 kW to 70 kW to today’s systems, which can have individual ratings of 200 kW to 250 kW. Packages up to 1 MW are now available that can be assembled into multipac units for projects of 5 MW to 10 MW. These modern units are packaged with integrated digital protection, synchronization, and controls; they produce high combined heat and power efficiencies; and they are capable of using multiple fuels.

Smart Power Generation at UCSD

The University of California, San Diego has been accumulating awards for its savvy use of a constellation of power generation and energy-saving technologies. The campus already controls a fully functioning microgrid—including a cogeneration plant—and, as befits a research institution, is constantly looking for new ways to make its energy system smarter. This “living laboratory,” as campus leaders like to call it, demonstrates what it takes to build a smarter grid and why the effort is worth it.

NFPA Gas Purging Rules Updated

The CSB has made urgent recommendations to the NFPA and the International Code Council to prohibit indoor purging and require companies and installers to purge flammable fuel gases to safe locations outdoors, away from workers and ignition sources.

Top Plant: Timelkam Power Plant Vöcklabruck District, Upper Austria, Austria

Now that the 412-MW Timelkam Power Plant has replaced a 47-year-old coal-fired power plant located in the Vöcklabruck District, northern Austrians can bid auf wiedersehen (goodbye) to high levels of air pollution. Compared to its predecessor, the new gas-fired combined-cycle plant has dramatically cut CO2 and NOx emissions and produces seven times more energy.

Top Plant: Sloe Centrale Power Plant, Vlissingen-Oost, Zeeland Province, Netherlands

There’s nothing slow about the fast-track operations at the new 870-MW Sloe Centrale Power Plant. The combined-cycle plant is designed for 250 starts per year and is capable of supplying power to the grid within a mere 30 to 40 minutes. In addition to its impressive rapid load response, the gas-fired plant produces low CO2 and NOx emissions by using the latest technology. It also attains an efficiency of 59%.

Top Plant: Ras Laffan Power and Water Plant, Ras Laffan Industrial City, Qatar

At the Ras Laffan Power Co. facility, the 756-MW net combined-cycle plant and the integrated 40 million gallons per day desalination plant are working in tandem to provide abundant, reliable electricity and desalinated water to residents of the State of Qatar, the most prosperous nation in the Middle East.

Top Plant: Panoche Energy Center, Firebaugh, California

The Panoche Energy Center is a 400-MW simple-cycle power plant using four of General Electric’s GE LMS100s with fast-start capability. Dispatched by Pacific Gas & Electric to meet regional power and grid stabilization needs, the project entered commercial service two months earlier than planned. Panoche is the largest LMS100 peaking facility in the U.S.

Top Plant: Langage Combined Cycle Power Plant, Plymouth, Devon, UK

The UK grid, focused on adding valuable renewable generation, will rely on natural gas–fired generation for many years to come. One of the most recent additions is the Langage Power Plant, designed for quick response and low load “parking” at night while remaining below air emissions limits. With an extraordinary architectural design that blends into the natural surroundings, Langage is now a local landmark.
