Nathan earned his Bachelor of Science in Chemical and Mechanical Engineering from the University of Tennessee at Chattanooga in 2009. 12-months prior to graduation, Nathan began an engineering internship with TVA’s Gas Operations Outage Department. This experience allowed him to develop a general understanding of TVA’s business and the multifaceted approach taken to perform well executed outages for the gas turbine fleet.

From 2009-2013, Nathan served as an entry-level combustion turbine systems engineer for TVA’s Gas Operations Outage Department. This role allowed him to further develop his understanding of gas turbine outage work, engineering development, project management, and asset management. Responsibilities included outage engineering support and emergent issue resolution, long range outage planning and scope development, component repair specification development and contract management, and other project engineering/management activities.

From 2013-2015, he has served as a senior-level CT systems engineer in the same department for TVA. This position continued to build on the skills developed during his time as an entry-level engineer and enabled Nathan to carry more responsibility for engineering outage support, technical contract development and management, and long range outage scope development and planning for TVA’s Gas Operations Assets (122 Units). In addition to these responsibilities, Nathan has been tasked with performing detailed analysis for short and long-term contracts, project cost/benefit analysis, business plan development, and collaborative efforts for special projects within TVA.

From 2015 to Present, he has served as a senior program manager for gas fleet strategy and most recently took over the leadership role as a senior manager for the major maintenance support group. This team provides strategic long range major maintenance planning, operations tracking and prediction, labor and material resource strategic planning, long term service agreement and contractual analysis/negotiations, gas turbine parts program pedigree, centralized parts management facility, and other technical and commercial evaluations.

Nathan has served on CTOTF™’s GE Large Frame “F Class” Roundtable, has supported the “B/E-Class” and is happy to bring his knowledge and skills to support Siemens/Mitsubishi Roundtables as the senior chair. He accepted the role as The Siemens/Mitsubishi Senior Chair in Spring 2017.
