Professional Experience
Jeffery Ellis is an engineering professional with a strong technical background and a deep understanding of the electrical utility industry. Mr. Ellis has over 20 years of power system experience with expertise in transmission system planning and operations, distribution planning and operations, and power quality. Mr. Ellis joined Utility System Efficiencies, Inc. (USE) in 2002 and is a Principal Power Systems Engineer. At USE, Mr. Ellis has completed a wide range of projects such as steady-state, transient stability, post-transient, reactive margin studies and system impact studies. In addition, Mr. Ellis has written a number of Python programs to increase efficiency, which is used in the Siemens PSS/E program.
Mr. Ellis has worked for utility and regulatory segments of the industry and has a strong working knowledge of the analytical tools that support system performance evaluation and capital planning processes used by electric utilities.
While employed at California Independent System Operator (CAISO) from 2000-2002 in the Operations Engineering department, Mr. Ellis developed and modified tools in EPCL and Visual Basic, which enhanced the development of the Fresno Generation and Pumping Nomograms. In addition, these tools increased efficiency, accuracy and ease of data manipulation. A dynamic Nomogram for the local Fresno system was developed for the CAISO system operators. This Nomogram utilized the capability of the plant information system application program to extract real-time data into a spreadsheet that plotted the system conditions and allowed the operators the ability to visually determine their operating point relative to the Nomogram curves. Mr. Ellis evaluated, suggested modification to, recommended re-schedule of, and approved clearances for both the bulk system and the local Fresno area, and assessed numerous complex clearances which required engineering analysis.
While at Pacific Gas and Electric Company (PG&E) from 1997-2000, Mr. Ellis was responsible for operation of the distribution system in the Napa Valley, determined capacity projects based on power flow modeling for planning of the distribution system, responded to power quality anomalies in the field, and assisted in the strategic deployment of SCADA equipment for the increased response of field equipment.
