Turning a profit in the business of electric generation can be challenging given the competitive nature of the industry today. Be prepared to take advantage of revenue opportunities, which can surface quickly, by upgrading equipment capable of improving your balance sheet tomorrow. A case in point concerns fogging systems. Those responsible for gas turbines know […]

Large-scale battery energy storage systems (BESS) continue to demonstrate their ability to meet specific functional requirements of grid operations and management under a variety of business models and ambient conditions. Los Angeles Department of Water and Power (Ladwp) is the latest to add a BESS, primarily for transmission-line stability. It follows several recent projects with

Some veteran gas-turbine (GT) asset managers have already been given responsibility for grid-scale storage facilities. Others may find their asset portfolio shift in this direction soon. If you are in this camp, or if you just want some technical guidance around this new asset class, get a copy of the Advancing Contracting in Energy Storage

The 2019 conference of the Combined Cycle Users Group (CCUG) was a prime example of “working together,” co-located with the generator (GUG), steam turbine (STUG), and powerplant controls (PPCUG) user organizations. Attendees were invited to participate in sessions conducted by all four groups at the Marriott St. Louis Grand, St. Louis, Mo, August 26-29. On

In what GE claims to be the largest gas turbine black-started by a modern battery, Entergy Louisiana has added a 7.4 MWh lithium-ion (nickel-magnesium-cobalt chemistry) unit at its Perryville power station to restart a 2001-vintage, 150-MW 7F.03 peaking gas turbine/generator should grid power be lost. To re-energize the grid, black starts typically require separate gas

The turnkey digital front end (DFE) solution for aging, unreliable, or obsolete gas turbine load-commutated inverter (LCI) starting systems, described last year in CCJ ONsite, now has a user testimonial and operating experience supporting it. John Chaya, operations manager at Cogentrix’ Rock Springs (Maryland), reports that the installation by Turbine Controls & Excitation Group Inc

With a little luck, you’ll never experience significant rub damage to your rotors. By design, OEMs usually provide generous clearance between the rotor and non-rotating parts except where it’s unavoidable: bearings and seals. OEMs mitigate the rubbing risks associated for those close clearance components with smart material selection—such as Babbitt, brass, and nylon. Those features
