What's the endgame? The portfolio includes a 120MWh battery system serving a hyperscale data-center customer in PJM.

It says that flexibility speeds up interconnection and cuts the need for costly grid upgrades that would otherwise land on other ratepayers.

Why now? Data-center operators want faster routes to power while PJM and federal regulators work out how to connect large loads. "Data center operators are choosing on-site energy storage because it is a fast, reliable, and effective way to get online," said chief executive officer Phil Martin.

By the numbers: Calibrant now holds more than 5.9GWh of battery storage in operation, under construction, or under exclusive development agreements — including further sites with the same hyperscale customer.
