Principal, Pellow Energy Insights
Lessons learned from microgrid feasibility studies in Pennsylvania, Louisiana and Tennessee
Matthew A. Pellow, Ph.D. is an independent energy storage technology analyst and consultant, engaged in critical technology review and cost/benefit assessment. He is engaged in analysis of grid-connected energy storage use cases, emerging battery and non-battery energy storage technologies, and hydrogen systems deployment and integration. Dr. Pellow was previously a scientist in the Energy Storage and Distributed Generation Program at the Electric Power Research Institute (EPRI) in Palo Alto, California; and a staff chemist at General Electric Global Research in Niskayuna, New York. He holds a doctorate in chemistry from Stanford University and a bachelor’s degree in chemistry from Columbia University, and is the co-author of seven peer-reviewed scientific publications.
Several microgrid sites were assessed using an integrated microgrid cost-benefit analysis framework developed by the Electric Power Research Institute. The framework integrates a variety of important considerations, including identifying associated costs, regulatory issues, and avoided costs of reliability and resiliency. Careful consideration of control methods is essential for maintaining the reliability, resiliency, and adequacy constraints of the grid, ensuring adequate economic margin in microgrid operation as well as the ability to serve critical loads in case of upstream network faults. The case studies explore sensitivities around microgrid design and operational parameters (e.g. customer type, single vs aggregation of loads, electricity rate & structure, islanding duration).
