Cal Poly Pomoma, Microgrid Feasibility Study
March 2020 - September 2020
Cal Poly Pomona contracted P2S to perform a microgrid feasibility study for their campus. This study included a review of their current utility bills and energy usage, a review of their onsite power generation sources, identification of potential PV installations and possible locations for a battery storage system. The study was the first step for Cal Poly in their mission to increase the reliability of their electrical system and improve their resiliency in the case of a power outage.
Our microgrid team first went onsite for a field investigation to determine existing conditions. They verified current energy usage levels and compiled all existing onsite generation sources at the campus. The team also found several sites for PV installations and a battery storage system. Next, was the task of evaluating how to tie in onsite generation sources to the existing campus electrical system to form a microgrid. They also evaluated electrical system islanding capability to close off the system in the vent of an outage. The team reviewed current campus loads that could be shed in event of demand exceeding generation and provided schematic single line and riser diagrams showing required microprocessor-based relays, automation controllers, load shed processors and network switches for islanding and the forming of a microgrid. At the conclusion of the study, the team delivered a feasibility report identifying existing conditions, evaluations and recommendations.
