First 7FA.05 Gas Turbines go Commercial at Xcel Cherokee
Two new 2 × 1 combined cycles with the latest 7FA.05 gas turbine technology from GE came on line at Xcel Energy’s 569-MW unit at the existing Cherokee Generating Station in Denver in August. Commissioning came just three months after first fire in May, which is significant because of the summer peaking period and the location of Cherokee and its importance to the Denver grid.

Gas Turbine Combined Cycle Fast Start: The Physics Behind the Concept
GTCC startup optimization is essentially minimizing the time required to reach the dispatch power (e.g., full load or a specific part load) without "breaking anything" in the process. For example, failure to control thermal stresses results in cracks via low/high cycle fatigue (LCF and HCF) and brittle fracture. This article provide relevant and easy-to-use technical information (in the form of simple charts, basic equations and representative physical quantities) to form an informed opinion on available technologies for GTCC startups.

The New H-100 Gas Turbine: Higher Output and Efficiency
Mitsubishi has traditionally targeted large gas turbines, whereas Hitachi focused on the small and medium-size market with its H-25 and H-100 models, often referred to as the H-series. The merger of the two companies’ thermal power businesses in early 2014 created Mitsubishi Hitachi Power Systems with products spanning from approximately 30 MW to 330 MW in simple cycle. Recent mid-size capacity additions include the H-100(110), H-50, and an uprate of the H-25 gas turbines to 42 MW.

Are Flexible Generation Plants Performing as Expected?
This article reviews the performance of the Siemens Flex-Plant installed at the Lodi Energy Center in Lodi, California. Designed to be highly flexible, fast-ramping and fast-cycling to complement renewable power generation, the facility experienced 380 starts over the two-plus year period from November 2012 to January 2015. The consensus is that the facility has lived up to expectations, although operational and maintenance costs are higher than for a typical combined cycle plant.

Gas Turbine Technologies for the Transition
About 60 GW of coal-fired generation in the U.S. will be retired by 2020 and about 35 GW of nuclear capacity will be retired by 2025, according to recent projections by Black & Veatch. Much of that capacity will be replaced with power produced by low-cost, cleaner-burning natural gas. This article reviews the installation of Siemens new FlexPlant technology at the El Segundo Energy Center in California and GE’s new H-class turbines at the Riviera Beach Energy Center in Florida.

Quickly Boost Your Combustion Turbine Response
PowerPhase LLC has developed a new technology called TurboPHASE, a fast-responding, modular “turbocharger,” that can boost the capacity of an existing simple cycle or combined cycle plant by 10% or more in seconds. The system consists of a compressor that delivers hot compressed air to the discharge section of a combustion turbine, thereby allowing it to operate at the rated capacity irrespective of ambient air temperatures. Morris Cogeneration, a combined cycle cogeneration plant near Chicago, installed TurboPHASE, to boost capacity when needed during cold weather events.

KOMIPO Relocates an Entire Combined Cycle Power Plant
South Korea has experienced years of booming electricity demand that has run ahead of its ability to maintain safe reserve margins. Korea Midland Power (KOMIPO) had an underutilized combined cycle plant in Boryeong that it decided to dismantle and move 100 miles away to Incheon to meet demand, rather than building an entirely new plant.

Don't Let Startup Emissions Slow You Down
In a Power Enginerring article, the authors point out that new combustion turbine (CT) simple and combined-cycle plants face new challenges in permitting because of more stringent startup emission limits. Recent permits issued in a variety of jurisdictions have included limits on startup emissions, both in mass per start and rolling annual startup mass limits for VOC, NOx and CO. The increased use of heavy duty/frame CTs for peaking applications create additional challenges. Startup and shutdown durations and emissions rates vary widely depending on CT model and other plant equipment and design choices.
