Andrew Howell
Technical Executive, EPRI

Responsibilities at the Electric Power Research Institute include participation in the Cooling Systems Technologies and Equipment program in the Fossil Generation Sector. In this capacity, Andy serves as a subject matter expert on research programs and projects associated with power-generating facilities involving cooling water and technologies (advanced cooling focus) and steam cycle chemistry, He joined EPRI's staff in January 2018 after working for 36 years in power-generation with Xcel Energy, undertaking tasks encompassing a wide variety of chemistry and materials issues. Areas of interest have included copper in the steam cycle, chemistry-related boiler and condenser tube deposition and failures, steam turbine deposition and failures, metals transport including flow-accelerated corrosion, dry/hybrid cooling, and chemical treatment processes for water in steam cycles, cooling systems and river discharges. Andy has been involved with the Air-Cooled Condenser Users Group since its inception in 2009. He has a Ph.D. in Chemistry with Metallurgy minor from the Colorado School of Mines and M.S/B.A. degrees in chemistry from the University of Missouri-Columbia.
