Energy storage projects, particularly battery energy storage systems (BESSs), have flooded interconnection queues across North America “overnight”. Standalone BESS projects as well as BESS coupled with renewable energy generation components – hybrid plants – are some of the most common resources being studied for interconnection today and will likely comprise a significant portion of the resource mix in the future. LBNL reports that by the end of 2020, 755 GW of total generation capacity. 200 GW of energy storage is currently seeking interconnection! The rapid increase of BESS and hybrid projects on the bulk power system (BPS) warrants a look at where this technology started and how it can positively impact the BPS. This article will explore increasing levels of BESS and hybrid plants from different perspectives and angles. BESS and hybrid plant equipment manufacturers will share latest advancements in equipment capabilities. Plant developers and designers will provide examples of new projects and engineering considerations. Transmission planners and operators will share their key focus for ensuring reliable and resilient operation of the BPS with growing levels of BESS and hybrid plants.
