Calibrant Energy Secures $145M in Solar and Storage Debt

A zero-capex energy contract still needs somebody to fund the equipment. Calibrant Energy has arranged another source of that capital through a $145M debt facility, announced November 10, 2026, to recapitalize operating assets and fund new solar and battery-storage construction across US power markets.

Investec led the financing, with Citi, Liberty Bank and Siemens Financial Services participating. The financed portfolio includes a 120 megawatt-hour battery energy storage system for an unnamed hyperscale data center customer in PJM, connecting the transaction to a practical question for large electricity users: how much sooner can a facility receive power when it gives the grid more control over its demand?

Calibrant develops, owns and operates on-site energy infrastructure, allowing customers to purchase services without the initial equipment expenditure. The commercial significance of the financing sits in that division of responsibility: the customer wants a usable energy outcome, while the provider has to organize the assets, capital and operating work that produce it.

What Calibrant's $145M debt facility finances

Calibrant's financing announcement describes 2 uses for the facility: recapitalizing assets already operating and supporting new construction. The announcement does not disclose how the proceeds divide between those jobs, or the facility's interest rate and maturity. Reporting the total as a corporate equity round would obscure both the financing structure and the work it supports.

Existing assets and construction projects occupy different positions in an energy developer's business. Recapitalization changes how an operating portfolio is financed; construction capital helps carry equipment and development work toward service. Bringing both into one announced facility gives Calibrant a financing tool that reaches across those stages, although the public release leaves the detailed allocation private.

The PJM battery is identified by its 120 MWh energy capacity. Calibrant has not named the hyperscale customer, disclosed the project's power rating, or supplied a commissioning date in this announcement. CEO Phil Martin points to financial close and site mobilization as evidence that large-load flexibility has reached commercial deployment. That is a more specific milestone than treating the project as an already operating storage installation.

For infrastructure readers, the distinction makes the announcement useful. It records financing and mobilization around a particular customer requirement, with the construction and operating obligations still attached to the equipment being financed.

How storage changes the utility conversation

A data center's electricity requirement includes timing as well as volume. On-site battery storage can help manage when a facility draws from the grid, giving the utility and its customer another way to work through a constrained connection. Calibrant presents its Path to Power offering as a way to develop those arrangements through engineered flexibility assets.

The company's Aligned Data Centers case study describes a 31 MW / 62 MWh battery at the Hillsboro, Oregon campus. Calibrant says the project was designed to enable earlier utility access than conventional infrastructure upgrades would allow. The relationship matters because the battery is serving a connection problem alongside the customer's computing requirements, rather than entering the story only after an outage.

The October 2025 joint announcement described collaboration with a regional utility from the start of negotiations. That gives the model an important practical feature: storage design and the power-service conversation can develop together. The particular utility, site and load profile still shape the arrangement, so a battery capacity figure alone cannot promise an accelerated connection elsewhere.

Aligned's Oregon project is separate from the unnamed hyperscale customer identified in the new financing. Keeping those records distinct preserves what is actually known while showing how Calibrant has been developing the commercial approach across more than one setting.

Who carries the asset and performance work

Calibrant's service-delivery model runs from energy assessment and engineering through financing, construction, operations and long-term asset management. The company says its service fees are linked to system performance. A customer evaluating the offering is therefore considering a continuing operating relationship as well as the physical equipment installed on its site.

That structure gives the financing a customer-facing consequence. Removing the initial capital expenditure can make an energy project easier to consider within a customer's own investment plan, but the provider must still assemble the people and funding to deliver it. The debt facility belongs inside that explanation of the product, because the commercial promise depends on infrastructure that somebody else owns and maintains.

Calibrant's current leadership includes CEO Phil Martin, CTO Freddy Reyes Falck and CFO Taimur Sheikh. Their respective functions sit alongside delivery, commercial and regulatory capabilities in a business selling a long-running energy outcome. The company has not disclosed individual responsibilities for negotiating this facility, and the public record provides no basis to assign them.

The model has roots in the 2020 venture launched by Siemens and Macquarie's Green Investment Group. Calibrant now identifies Macquarie Asset Management as its backer. That institutional origin helps explain the combination of energy-service delivery and financing, without converting the new project debt into a conventional startup equity narrative.

The portfolio beyond one hyperscale customer

Calibrant's public project record also includes a February 2026 agreement with Iron Mountain for 23 MWh of storage at a New Jersey data center. The planned system pairs with an existing 7.2 MW rooftop solar installation. It is another specific customer arrangement, with a different configuration from the Aligned battery and the newly financed PJM project.

Across the business, Calibrant reports more than 5.9 GWh of storage in operation, construction or exclusive development agreements. That combined-stage figure describes a wider opportunity and execution workload, rather than a fully commissioned fleet. Its company history also records the 2024 acquisition of Enel X's distributed energy solutions business, adding operating assets to the capabilities under one roof.

The financing belongs to a wider infrastructure discussion that also appears in DevCuration's coverage of distributed solar project capital and onsite energy procurement. Capital structure, equipment choices and the customer's buying process all influence how an energy project reaches a useful operating life.

For Calibrant, that work now includes additional sites with the same unnamed hyperscale customer, according to the financing release. Each site brings another utility relationship, another demand profile and another installation to operate. The $145M facility extends the financing behind those conversations as the company works to turn a customer's requested power into an arrangement the surrounding grid can support.
