Calibrant Energy closed a $145-million debt facility led by Investec to finance solar and battery storage projects. Citi, Liberty Bank, and Siemens Financial Services also participated in the facility.
Why it matters
Data center operators are looking for ways to come online faster while PJM and federal regulators work through how large power users connect to the grid. Battery storage that lets facilities control when they draw power could ease those connection pressures.
The facility funds a 120-MWh battery energy storage system serving a hyperscale data center in PJM and more than 5.9 GWh of Calibrant battery capacity across operating, under-construction, and exclusive-development sites. The disclosed figures do not specify the solar capacity financed or the completion dates of the projects.
The players
Calibrant Energy
Calibrant Energy is a developer of battery energy storage and solar projects that offers turnkey storage solutions to large power users.
Investec
Investec is a specialty bank and asset manager that led the debt facility financing Calibrant's solar and storage projects.
The details
Investec led the $145-million facility, with Citi, Liberty Bank, and Siemens Financial Services also participating. Calibrant offers engineered battery systems that give energy-intensive facilities control over how and when they draw power, and says it provides turnkey, zero-capex solutions to large power users.

The Tech Race
Data center developers are competing to secure grid access as PJM and federal regulators revise how large power users interconnect. Storage that lets facilities shift when they draw power is emerging as one way to speed that process.
For people in PJM states, faster data center interconnection could affect how quickly new large-load projects come online and what grid upgrades are needed. Storage that reduces the need for costly infrastructure work may influence regional utility planning.
The takeaway
Battery storage that gives data centers control over their power draw may become a practical tool for getting large loads connected faster. Watch how PJM's interconnection rules evolve as these projects move forward.
