Best Practices

The spate of lawsuits filed in the aftermath of the 2021 winter storm that left millions in Texas without power for days and sent natural-gas prices soaring to their highest levels in years—up nearly 17,000% in some cases, according to a Wall Street Journal report—testify to the value of having dual-fuel gas turbines as part […]

The numbers are eye-opening: 20-MW gain in simple-cycle output, 3.8% heat-rate improvement in simple cycle, a stable GT turndown to 38%, and less than 9-ppm NOx across the load range. That’s what PSM and Salt River Project’s (SRP) Desert Basin Generating Station reported at the 2021 501F Users Conference after upgrading a 2001 vintage Siemens

Turbine Tip No. 14 from the PAL solutions library applies to General Electric package power plants (PPP) incorporating MS5001 and MS6001 gas turbines GE offered these two gas-turbine models requiring speed-reduction gearboxes to drive 2-pole ac generators (Fig1): The MS5001 package power plant manufactured by the OEM in Schenectady from 1960 to the mid-1980s. The

With just a few excellent slides and a tag team of a design specialist and a construction specialist, Greg Rueff, Vogt Power International, and Tim Holland, TEiC (a Babcock Power company), showed attendees at the first installment of the HRSG Forum’s Supplier Workshop Series that sometimes you have to “redesign and replace” to relieve your

Plant managers diligently pursue O&M strategies that have a high probability of success for keeping their electric generating assets in service throughout the “must-run” season—this to assure a profitable year. Deciding on what inspections are necessary to access the information needed for reliable decision-making is part of the challenge. Today’s meager budgets do not allow

In a webinar August 12, experts from Mitsubishi Power Americas (MPA) shared a first-order long-term modeling exercise which showed that a centralized hydrogen storage facility and hydrogen-fueled prime movers can economically avoid having to curtail wind and solar energy in the Western Electricity Coordinating Council (WECC) and improve carbon footprint even further than a baseline

The first thing to note about the GE presentations made at the 2020 virtual conferences of Power Users’ Combined Cycle, Power Plant Controls, Steam Turbine, and Generator Users Groups is that you’re probably going to want to listen to the recordings, if you’re approved to access them at the OEM’s MyDashboard website. For the Power

A 480-MW 1 × 1 combined cycle was experiencing NOx emissions above its 2-ppm stack permit limit. The problem was more pronounced with supplementary firing, so the plant was restricted both in its level of duct firing and overall output. This HRSG, which incorporates a heat-recovery section directly upstream of the SCR (the “box” in

A presentation entitled “Does Your Backup System Work—Really?” during Week Three of the Combined Cycle Users Group (CCUG) 2021 virtual conference reminds why user groups can be worth their weight in gold. The presenter, asset manager for a 600-MW, 2 × 1 combined cycle with Siemens 501FD gas turbines and a KN steam turbine/generator, reviewed

The COMBINED CYCLE Journal and the steering committees of the industry’s leading gas-turbine users groups—including 7F, 501F, 501G, 7EA, Western Turbine, Frame 6, 501G, 501D5-D5A, AOG, and V—collaborate to expand the sharing of best practices and lessons learned among owner/operators of large frame and aeroderivative gas turbines. Thirty-one plants listed below participated in the 2021
