Solar Subsector Manager
Solar Subsector Manager


Tom was named PNNL's subsector lead for the U.S. Department of Energy Office of Energy Efficiency & Renewable Energy’s Solar Energy Technologies Office (SETO) in April 2018. With a growing focus on grid integration, SETO will benefit from Tom's specialized background. Tom is an IEEE Fellow who has spent many years working on inverter technology design and integration of solar systems with the grid. Tom joined PNNL in August 2016 to provide technical leadership and project management for the research portfolio in distribution analysis and automation, demand response, and distributed energy technologies. His primary research focus is on novel simulation, modeling, and analysis capabilities. Before PNNL, he was at the University of Pittsburgh, MelTran (his own company), Enernex, Ansoft (now part of ANSYS), Electrotek Concepts, PTI (now part of Siemens), and Westinghouse Electric. Tom's career highlights include contributions to OpenDSS and other open-source software, standards (IEEE 1547, 1410, 1243, and 1729, along with IEC 61968), and commercial software products (PQWeb, Maxwell, and SIMPLORER). He has conducted many grid consulting projects that span modeling, analysis, and measurements taken in the field. Tom has also taught nine different undergraduate and graduate university courses for credit. At PNNL, his largest projects have been software simulation platforms for transactive energy systems and for distributed applications, along with power system protection, inverter controls, and energy storage integration.
