LOWELL, Mass. - [September 20, 2017] - TRC Companies Inc., a leader in engineering, environmental consulting and construction-management services, welcomes Paul DiFilippo, P.Eng., as Principal Electrical Engineer in TRCs System Protection department. In this role, DiFilippo will be responsible for protective relay engineering and technical support, as well as NERC PRC and NPCC technical support within TRC’s System Protection Engineering practice.

“Paul brings years of operational and leadership experience in Protection Asset Management as well as deep understanding of what utilities and transmission operators need to do to comply with North American Electric Reliability Council (NERC) and Northeast Power Coordinating Council (NPCC) standards,” said Jerad Pelotte, System Protection Manager at TRC. “Paul has played a key role in drafting many of the NERC standards, and his unparalleled expertise in this area makes him an invaluable source of counsel for our utility clients as they navigate the continual change within the utilities industry and its regulatory landscape.”

With more than 30 years in the protection and control discipline, DiFilippo has obtained significant experience in commissioning, maintenance, protection system fault analysis, protection standards, strategies, asset management, and NERC PRC standard compliance, as well as providing leadership and support to field protection and control staff. 

Most recently, DiFilippo served as a Manager of System Protection Asset Management at Hydro One Networks, Inc. in Ontario, Canada’s largest electric transmission and distribution service provider. In that role, he oversaw protection and control within the Transmission Asset Management function and helped develop compliance guidance documentation for all NERC PRC standards, including NERC PRC-005, which became the basis of the company’s current compliance program. In 2011 DiFilippo represented Hydro One on the NERC standards drafting team for a revised NERC standard PRC-004 on Protection System Misoperations. 

In addition to his leadership at Hydro One, DiFilippo has served in various roles on the NPCC’s Task Force on System Protection since 2008, including as vice chairman and chairman. In 2009, he participated on the standard drafting team for the NERC regional standard PRC-002-NPCC-01, which was later superseded by NERC PRC-002-2 to cover all of North America. DiFilippo continues to serve on the NPCC Task Force as a general member representing TRC.

DiFilippo is a Licensed Professional Engineer in the Province of Ontario and a member of the Institute of Electrical and Electronics Engineers (IEEE) and the IEEE Power and Energy Society. He holds a Bachelor of Applied Science in Electrical Engineering (Honors) from Queen’s University in Kingston, Ontario, and has completed additional studies in financial accounting and Canadian financial securities.
