If you’ve flown on a commercial airplane, you’ve likely sat within a hundred feet of an operating gas turbine engine. Gas turbines have been used to power aircraft since the 1940s. But gas turbines like those on airplanes are also used for generating electricity. These designs are known as aero-derivative gas turbines and occupy a […]

The Virginia State Corporation Commission (SCC) on Aug. 23 rattled American Electric Power’s (AEP’s) plans to operate the 2.9-GW John Amos and 1.3-GW Mountaineer coal power plants through 2040 when it partly denied cost recovery for expenses that the West Virginia plants need to comply with the federal Steam Electric Effluent Limitations Guidelines (ELG) rule. The […]

Residential applications for smart grid technologies continue to grow as electricity customers take more control of their energy usage and costs. Homeowners with rooftop solar have been selling power back to the grid for years, and more opportunities for power customers are coming as electric vehicle owners tap into the market via energy storage. Homeowners […]

Mechanical Dynamics & Analysis (MD&A) announces Portable In-Situ Air Flow Test stand capabilities that allow for immediate and conclusive data on gas turbine nozzle performance. This flow test apparatus provides efficient gas turbine air/gas flow analysis and is offered by MD&A Fuel Nozzle Services Division/ Integrated Combustion Solutions (ICS).

Mechanical Dynamics & Analysis (MD&A) recently completed an overhaul at a combined cycle plant consisting of gas and steam turbine majors, a steam turbine generator minor inspection, and a gas turbine generator major inspection. The customer combined scope was the largest single project implemented at the site since the combined cycle plant was commissioned. MD&A sent all 3 rotors from […]

Mechanical Dynamics & Analysis’ Control Systems Division (MD&A Control Systems) replaced an industrial co-gen turbine’s original mechanical-hydraulic (MHC) controls with an electronic governor, electro-hydraulic trip system and self-contained control valve actuator. The primary drivers for the project were the operator’s desire to increase the long-term maintainability and reliability by replacing the MHC components that had […]

The pace of installations of renewable energy projects across the first six months of 2021 hit a new high for the sector, according to a report released Aug. 24 by the American Clean Power Association (ACP). ACP, which works with solar, wind, energy storage and power transmission companies to promote renewable energy, said the U.S. […]

The California Energy Commission (CEC) has approved licenses for gas-fired power units to help the state cope with continued electricity shortages. The move comes after Gov. Gavin Newsom earlier declared a state of emergency for California’s power grid. The state’s Dept. of Water Resources is procuring what it called five temporary gas-fueled generators, each with […]

An experiment at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) appears to have approached fusion ignition as it recreated the extreme temperatures and pressures at the heart of the sun for a tiny fraction of a second. The momentous step has fueled new optimism for fusion energy. The experiment on Aug. 8 “was […]
