Orlando, Florida— Gas Turbine Efficiency plc (AIM: GTE), a leader in energy services and aviation products is announcing the appointment of John Duff to the senior staff. Mr. Duff will be responsible for business development and strategic power generation initiatives.

John Duff brings to GTE over 32 years of experience in the power generation industry, including more than two decades in management. Prior to joining GTE, Duff was Senior Vice President of Entegra Power Group, LLC where he was responsible for the strategic leadership of the power plant operations, maintenance, engineering, capital project management, environmental, and corporate insurance functions.

Mr. Duff’s former employer, Entegra, owns and operates 4400 MW of natural-gas-fired combined-cycle merchant capacity with a fleet of 16 General Electric Model 7FA/DLN2.6 gas turbines with heat-recovery steam generators (HRSGs) from Alstom Power Inc, and eight GE Model D11 steam turbines. Under Mr. Duff’s direction, Entegra unbundled traditional OEM long term service agreements and successfully self-performed operations and maintenance, management of outages, and modernizations and upgrades for improvements in output, heat rate, reduction of life cycle cost, improvements in availability, reliability and emissions reductions.

John Duff began his career at TECO Energy, Inc. where he worked for almost three decades, climbing through the ranks from production engineer in the regulated utility to company president at the unregulated power generation subsidiary —further supporting his qualifications as a power generation professional with the experience to help GTE achieve its strategic goals.
