Snohomish Public Utility District: An Assessment of Battery Technical Performance

Abstract

This report investigates the technical performance of the SnoPUD MESA-1 BESS facility, consisting of two battery sub-systems 1a and 1b, based on a number of baseline and use case tests. Baseline tests were intended to assess the general technical capability of the BESS (e.g., stored energy capacity, ramp rate performance, ability to track variable charge/discharge commands, direct current (DC) battery internal resistance) while the use case tests were intended to examine the performance of the BESS while engaged in specific economic services (e.g., arbitrage, power factor correction).
