Siemens supplied seven advanced aeroderivative gas turbines and
generators for Oklahoma Gas and Electric Company’s Mustang Plant
The company’s SGT-A65 fast-ramping units can reach full power
within ten minutes to provide grid flexibility and quickly meet peak
power demand
As the most powerful aeroderivative in its class, Siemens’
technology is a low-cost solution to balance fluctuations in renewable
power

WASHINGTON–(BUSINESS WIRE)–Siemens celebrated Oklahoma Gas and Electric Company’s (OG&E) gas-fired
generating station, Mustang
Energy Center, achieving full commercial operation in Oklahoma City,
OK on March 31. As the technology partner for the project, Siemens
supplied seven industry-leading aeroderivative gas turbines and
generators for OG&E’s Mustang Plant which now has an output of
approximately 462 megawatts (MW), and is capable of generating and
transmitting electricity onto the grid within ten minutes.

The seven SGT-A65 units can individually provide up to 66 MW of power,
helping to maximize output and meet the power needs of approximately
400,000 homes in Oklahoma City and within the Southwest Power Pool
transmission system. OG&E chose to replace the Mustang facility’s 1950s
area assets with Siemens’ SGT-A65 technologies because they are the
highest simple cycle efficiency gas turbines in their class and can
deliver the largest power output with the smallest environmental
footprint, resulting in significant cost and fuel economy savings.

With the new turbines and generators, OG&E’s Mustang Plant will be
highly responsive and fast-ramping with connections to nine transmission
lines to ensure rapid electricity delivery during periods of renewable
intermittency and emergency outages. The highly flexible SGT-A65 gas
turbines (formerly known as Industrial Trent 60) offer these
capabilities because they are derived from advanced aeroderivative
technologies originally designed for aviation which can produce full
power from a cold start in less than ten minutes.

“We’re proud to usher in this new era of generation technology,” said
OGE Energy Corp. Chairman, President and CEO Sean Trauschke. “Mustang
plays a critical role in the region’s growth and economic development.
We now have a plant that is more efficient, more sustainable and more
responsive while maintaining its legacy of providing affordable,
reliable power.”

“We are very pleased to have supplied some of the most modern and
advanced turbine technology to OG&E. These aeroderivative gas turbines
are fast-ramping, efficient, and help integrate renewable energy
technologies to ensure reliable power to customers in Oklahoma City and
its surrounding areas. As more renewable energy comes online, these
units are the perfect technology to support grid stability and help meet
demand for peak power,” said John Gibson, Country Division Lead for U.S.
Power and Gas, Siemens.”
