Vermont Electric Power Company (VELCO), which was formed in 1956, is the nation’s first statewide transmission-only company owned by Vermont’s 17 local electric utilities and Vermont Low Income trust for electricity (VLITE), a public benefit non-profit corporation who funds projects and initiatives that further the energy policies of the state of Vermont. VELCO’s Planning Department performs short term and long term planning studies to assess the performance of the system under various system conditions in terms of electric demand, generation dispatch and transmission system topology. The results of planning studies are only as good as the models representing the system. Planners use various tools to ensure that system models reflect reality. This task is complicated by the fact that VELCO planners do not have direct access to much of the data on the local distribution system. The planners use the PI System to analyze historical data and system events and ultimately understand how the system behaves. Without readily accessible data from the PI Server, the planning process would be less efficient, and there would be more uncertainty regarding study results and the appropriateness of system solutions. This presentation gives a brief description of some of the uses of PI System data in the planning process.
Hantz Présumé is Principal Engineer for VELCO’s System Planning Group at VELCO and has worked there since 2001. In his current role, Hantz conducts long-term planning studies and non-transmission alternative (NTA) studies. The PI System has been one of tools utilized to ensure study assumptions are realistic and proposed solutions are cost-effective. Prior to joining VELCO, he worked for ten years as a Planning Engineer at what was then Boston Edison, now Eversource, producing studies on long-term planning, large generator interconnection, and on a number of exploratory scenarios. One of these involved designing a transmission system without any installed generation in the greater Boston area. Hantz currently serves on the Reliability Coordinating Committee of the Northeast Power Coordinating Council, New England Power Pool’s Reliability Committee, and ISO-NE’s Load Forecast Committee and Distributed Generation Forecast Working Group. He received an MSEE in Power Systems from Northeastern University and an MBA from Boston College.
