Case study of a GE sodium hypochorite system water treatment installed at Entegra's Union Power Stateion. After the system was installed, the plant steadily reduced chlorine addition to the point it was finally stopped. A follow-up project was done to install a permanent hypochlorite injection system on it as well. Overall chemical cost has decreased by over 10%, a significant dollar amount for a facility of this size.

Yokogawa Supplies DCS Information Management System for Burcresti Vest Combined Cycle Plant
The Bucuresti Vest Combined Cycle Heat and Power Plant (CCHP) is located in the Romanian capital of Bucharest and supplies both electricity and heat to this city. Yokogama supplied its CENTUM CS 3000/UOI (Unified Operator Interface) control system which allows a single operator to interface with the plant's turbines, HRSG, balance of plant (BOP) facilities, and electrical systems.

GE Introduces New Gas Turbines Plants Rated at More than 61% Combined Cycle Efficiency
The most effective way to increase combined cycle efficiencies is to develop advanced gas turbine engine technologies capable of operating at even higher firing temperatures. GE is introducing a series of air cooled high efficiency gas turbines with firing temperatures of over 2500°F. The first 7HA turbine will be installed at Chubu Electric Power in Japan in 2016; the first 9HA turbine at EdF Bouchain in France in 2015.

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.

GE Ups 9HA Specs Following Completion of Validation Testing
After 200 hours of validation testing, GE has increased the efficiency rating for their HA series turbines by about a half point. For example, the 7HA.02 which had a simple cycle net output of 330 MW and 61.2% combined cycle efficiency last year is now rated at 337 MW simple cycle and 61.9% combined cycle efficiency in a 2x1 multi-shaft configuration.
