Professional Experience

Don DeBerry is an engineering professional with a strong technical background and a deep understanding of the electrical utility industry. Mr. DeBerry has over 29 years of power system experience with expertise in transmission planning, system operations, energy management system applications, operational compliance, and distribution engineering. Mr. DeBerry joined Utility System Efficiencies, Inc. (USE) in 2008 and is a Principal Power Systems Engineer. At USE, Mr. DeBerry has performed power flow, stability, post-transient, and short circuit analysis throughout the Western Interconnect. Mr. DeBerry has completed a wide range of projects that include; seasonal operational planning studies, generator interconnection studies, path rating studies, and power system model development. Mr. DeBerry is a member of the WECC Technical Studies Subcommittee and is developing expertise on the new NERC TPL-007 Standard to evaluate Geomagnetic Disturbances (GMD).

While employed at Sacramento Municipal Utility District (SMUD) from 2004-2008 as a Principal Transmission Planning Engineer, Mr. DeBerry was a member of the WECC Reliability Subcommittee and assisted with the development of SMUD’s transmission planning policy. He collaborated with various departments to expand the SMUD Ten Year Transmission Plan to better meet the mandatory NERC requirements. In this position, Mr. DeBerry also developed the annual FERC 715 filing and performed seasonal operating studies. He evaluated future generation additions, renewable resource integration, the retirement of expensive and/or older generation, and evaluated the capacity expansions for several of SMUD’s combined cycle units.

While employed at the California Independent System Operator (CAISO) from 2002-2004 in the Contract and Compliance department as a Senior Contracts and Compliance Engineer, Mr. DeBerry resolved technical issues related to operational performance standards and compliance enforcement procedures from CAISO staff and market participants. Mr. DeBerry acted as the Contracts and Compliance liaison to Grid Operations to identify and resolve operational compliance concerns. In this role, Mr. DeBerry developed procedures, technical criteria, and program applications to evaluate market participant compliance with the CAISO Tariff, contractual agreements, and operating protocols. Mr. DeBerry also assisted with the design and implementation of Uninstructed Deviation Penalties, No Pay charges for Ancillary Service provision, resource testing for Ancillary Service certification, and Unannounced Compliance Testing.

While employed at CAISO from 1997-2002, Don was the lead operations engineer for the Northern PG&E area and back-up operations engineer for the bulk 500 kV system and the Southern California Edison systems. In this position, Mr. DeBerry coordinated the workload of other CAISO operations engineers and provided technical assistance and training. He provided 24/7 on-call technical support, developed operating procedures, evaluated system reliability for scheduled transmission outages, investigated system disturbances, and assisted with the evaluation of transmission and generation projects. Mr. DeBerry interacted with various departments including: EMS staff, Transmission Planning, Real-time Dispatch, Scheduling, Market Operations, Client Services, and Outage Coordination.

While at Northern California Power Agency (NCPA) from 1987-1997, Mr. DeBerry represented NCPA in various WECC committees and study groups. He participated in the WECC Technical Studies Subcommittee, August 10 and July 2, 1996 WECC System Disturbance Groups, Desert Southwest Transmission Project, Alturas Transmission Project, Summit Transfer Capability Studies, Sacramento Valley Study Group, WAPA Transmission Assessment, Rancho Seco-Collierville Interconnection studies, WECC Program Evaluation Work Group, WECC GE MAPS Evaluation, and the GE PSLF Users Group. Don also evaluated various transmission and generation projects for NCPA members.

While at Sierra Pacific Power Company (SPPC) from 1985-1987, Mr. DeBerry worked with customers and line crews to investigate and solve distribution service problems. This position also required estimating project costs, acquiring materials, and developing work schedules. Mr. DeBerry also developed the first graphical representation of the SPPC transmission system with the WECC IPS load flow program, and validated data for the power flow and short circuit programs.
