Investec-led financing recapitalizes operating assets and funds new construction projects
BOSTON, Nov. 10, 2026 /PRNewswire/ -- Calibrant Energy, a leading provider of on-site energy solutions, today announced the close of a $145 million debt facility led by Investec for solar and battery storage projects across multiple U.S. power markets. The portfolio includes a 120 megawatt-hour (MWh) battery energy storage system (BESS) serving a hyperscale data center customer in PJM. Citi, Liberty Bank, and Siemens Financial Services also participated in the facility.
Data center operators are looking for ways to get online faster as PJM and federal regulators work through how large power users connect to the grid. Calibrant's engineered BESS solutions give energy-intensive facilities greater control over how and when they draw power. This flexibility supports faster interconnection timelines and reduces the need for costly grid infrastructure upgrades that would otherwise be passed on to other ratepayers.
"Data center operators are choosing on-site energy storage because it is a fast, reliable, and effective way to get online and operate as responsible grid citizens," said Phil Martin, CEO of Calibrant Energy. "With this financial close and site mobilization for a hyperscale data center, Calibrant continues to demonstrate that large-load flexibility is not just possible but a commercial reality today."
Calibrant's turnkey, zero-capex solutions unlock the path to reliable power that the world's largest power users need to grow their businesses.
"Investec is proud to support Calibrant and Macquarie on this transaction," said Fred Petit, Co-Head of Energy & Infrastructure North America at Investec. "We value the opportunity to partner with experienced investors and operators, and to provide financing that advances the energy transition and the critical infrastructure needed to meet growing power demand across the U.S."
Calibrant Energy now has more than 5.9 gigawatt-hours (GWh) of battery storage capacity in operation, in construction, or under exclusive development agreements, including additional sites with the same hyperscale customer. This growth reflects rising demand from large power users for on-site energy solutions that accelerate speed to power while easing strain on the grid. It also reflects customers' preference for a trusted, experienced partner that can develop, own, and operate these solutions and deliver the power outcomes their business plans depend on.
