Professional Experience

Joseph Gillette is an electrical engineer with over 13 years of experience performing power system studies in the electric utility industry. He was worked for a variety of entities in the electric utility industry, including a regulatory agency, large and small public utilities, and a private consulting firm. He has extensive experience performing steady-state, voltage stability, and transient stability studies and has experience demonstrating compliance with the Transmission Planner (TP) and Planning Coordinator-related (PC) NERC reliability standards.

Mr. Gillette rejoined Utility System Efficiencies, Inc. (USE) in 2019 as a Principal Power Systems Engineer and immediately contributed to the system impact study of a proposed 500kV project and several generator interconnection studies. Joseph was first employed by USE from 2010 to 2013 as a Senior Power Systems Engineer, during which time he completed a wide range of projects, such as steady-state, transient stability, post-transient, and reactive power margin studies for annual transmission system assessments, operating nomogram studies, interconnection studies, and a major Western Electricity Coordinating Council (WECC) three-phase rating process.

Mr. Gillette joined USE from the Sacramento Municipal Utility District (SMUD) where he was employed from 2009 to 2010 and again from 2013 to 2019. He was Manager of the Grid Planning Department from 2016 to 2019 where he led a staff of 6 engineers and was responsible for transmission planning of the 230 and 115-kV transmission systems. He was also responsible for the compliance of all relevant PC standards for SMUD, the Modesto Irrigation District, Roseville Electric Utility, and the City of Redding through SMUD’s participation in the Balancing Authority of Northern California (BANC). In addition, he was also responsible for all TP standard relevant to SMUD. Prior to his promotion to Manager, he was a Principal Transmission Planning Engineer from 2013 to 2016, when he performed numerous power system studies, including the first CIP-014 study and system impact studies for various proposed generation and load projects. During his first tenure at SMUD, which was from 2009 to 2010, he was an Associate Transmission Planning Engineer and performed power flow studies, minimum generation studies, and participated in the California Transmission Planning Group.

While at the Turlock Irrigation District from 2007 to 2009 as an Assistant Electrical Engineer and later as an Associate Electrical Engineer, Joseph Gillette performed power system studies in support of both the Transmission Planning Department and the Transmission Operations Department. He was also responsible for demonstrating compliance with the then-new reliability standards, including standards in the TP, TOP, FAC and EOP categories.

As an Energy Specialist in the Electricity Analysis Office at the California Energy Commission, Mr. Gillette assisted in the production cost modeling of the Western Interconnection to determine the effects of various scenarios and policies. He also created numerous computer programs and spreadsheets to collect and analyze various generation, transmission, and load data sets.

Prior to entering the electric utility industry, Joseph was a computer programmer with the State of California.
