SAN FRANCISCO, CA - Power grids are found globally in two frequencies, 50 Hertz in Europe, Asia and Africa and in 60 Hertz in the Americas, Japan, and Saudi Arabia. GE’s first launch of its FlexEfficiency technology was to the 50 Hertz market announced at Power-Gen Europe in Milan. (See World-Gen, V.23, Number 3, June 2011, “Grid Challenge Met.”)

Paul Browning, president and CEO, GE Thermal Products business said, “Today’s announcement positions GE with the broadest, most comprehensive gas turbine portfolio, delivering a combination of record-setting efficiency and flexibility. Like its 50 Hertz counterpart, the FlexEfficiency 50 Plant introduced in 2011, the FlexEfficiency 60 Plant is able to rapidly increase or decrease its power output in response to fluctuations in wind and solar power, enabling the integration of more renewable resources onto the power grid.” GE also announced that the company has secured nearly $1.2 billion in new orders for FlexEfficiency 60 technology for projects in the United States, Saudi Arabia and Japan.

The FlexEfficiency 60 Portfolio will include four gas turbines, the newest being the 7F 7-series. GE also enhanced the highly flexible 7F 5-series. A new 7F 9-series, configured to be the largest and most efficient in the portfolio, and an enhanced 7F 3-series will be available in the future.

The FlexEfficiency 60 Portfolio also includes an enhanced D-17 steam turbine, H26 hydrogen- cooled generator and Mark* VIe Integrated Control System that can be configured into the FlexEfficiency 60 Combined-Cycle Power Plant. FlexEfficiency 60 technology will be manufactured and tested at the world’s largest gas turbine manufacturing facility in Greenville, SC. GE invested $170 million to develop this full speed, full load test facility.

The $1.2 billion in new sales is comprised of orders for 19 gas turbines—13 for the 7F 5-series gas turbine and six for the new, larger 7F 7-series gas turbine.


GE will ship six 7F 7-series gas turbines to Chubu Electric Power Co., Inc.’s Nishi-Nagoya thermal power plant in Nagoya city, Japan. The plant will support the government’s initiative for cleaner, more-efficient energy production. It will produce more than 2,300 megawatts in combined-cycle operation. GE will supply the six 7F 7-series gas turbines to Toshiba, the engineering, procurement and construction contractor for the project. The first unit will be shipped in February 2016 with all six turbines expected to be in service by March 2018.


12 GE will supply eight 7F 5-series gas turbine-generators for the expansion of Saudi Electricity Company’s PP12 project, adding more than 1,990 megawatts. PP12 will be the largest air-cooled combined-cycle project in Saudi Arabia using GE’s F-class gas turbines and will be the first application of 7F 5-series gas turbines in the region. The gas turbines will burn natural gas provided by the Saudi national oil and gas company Saudi Aramco. The machines will be equipped with GE’s latest dry low NOx combustion technology to reduce emissions, extend maintenance intervals and enable the plant to operate more flexibly.


Two GE 7F 5-series gas turbines will power the Cherokee project in Denver, which will convert an existing coal plant into a cleaner burning, natural gas combined- cycle facility. The Cherokee repowering project is part of Colorado’s Clean Air Clean Jobs Act passed in 2010, which helps retire or retrofit the state’s coal plants. The new plant will be owned and operated by the Public Service Company of Colorado, a wholly owned subsidiary of Xcel Energy. GE expects to ship the gas turbines in the fourth quarter of 2013, with commercial operation beginning in the fourth quarter of 2015. The FlexEfficiency 60 Plant will avoid 2.6 million metric tons of carbon emissions per year when compared to an equal-sized coal power plant based on EPA data.


GE will provide two 7F 5-series gas turbines and a GE D11 steam turbine to Hess Corporation for an upcoming United States project.


GE will provide one 7F 5-series gas turbine for an industrial application in the Western United States. This new combined- cycle power plant will repower coal fired steam turbines with cleaner, flexible natural gas.


A custom-designed, 18-wheeler with interactive, state-of-the-art displays and demonstrations of GE’s FlexEfficiency 60 power generation portfolio is going on a 4,000 mile, four month road tour to 25 cities to help further educate customers, industry influencers and financers about the importance of natural gas and mixing it with renewables.
