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.
