Power for Data Centers: Microgrids, Behind-the-Meter Generation and the Capital Markets Gap
The binding constraint on data center growth is no longer land, fibre or chips. It is power — specifically, the years-long queue for grid interconnection. The response taking shape is generation built behind the meter: microgrids, on-site turbines and engines, batteries, fuel cells and solar, delivered as contracted power to a single large customer. It is proven technology in a familiar capital markets gap. This is how Lieef thinks about it.
The interconnection problem
Utilities plan on decade horizons. Hyperscale and AI data centers want hundreds of megawatts on timelines measured in quarters. Where those meet, interconnection queues stretch for years and utilities cannot build transmission and substations fast enough. The result is a market in which a data center with land, capital and customers may still not be able to switch on.
Behind the meter
The practical answer is to generate on site or nearby, either as bridging power until grid supply arrives or as a permanent primary or resilience supply. None of the underlying technology is new. Gas turbines and reciprocating engines, battery storage, solar and fuel cells are mature, well-understood and widely deployed. What is new is the configuration: a purpose-built microgrid serving a single, creditworthy, power-hungry customer under a long-term contract.
Framed that way, it is infrastructure. Long-lived physical assets, an essential end use, proven technology, and predictable contracted revenue. The profile is the same one we see in lighting as a service and managed fleet charging — capital equipment a customer needs but should not have to own, converted into a contracted service.
The gap
These projects are awkward for the existing capital stack. They are too small and too bespoke for utility-scale infrastructure funds built around gigawatt transactions. They are too capital-intensive for developers and equipment integrators to carry on their own balance sheets. And because the contracts are still being invented project by project, lenders cannot yet underwrite a portfolio of them the way they underwrite a portfolio of solar leases.
That is the capital markets gap Lieef was founded to close. The technology is proven. The customer demand is acute. What is missing is the standardised contract structure that turns power-as-a-service into a cash flow institutional capital can price — and the growth capital to execute it enough times that the structure becomes the market standard.
How our principles apply
- Proven technologies. Established generation and storage equipment from established manufacturers. No first-of-a-kind risk.
- Predictable cash flow. Long-term contracted offtake with a creditworthy data center or campus operator, not merchant power.
- No macro bets. Revenue that does not depend on power prices, commodity spreads or subsidy programmes.
- Buy and hold. Underwrite to hold to maturity on an unlevered basis; exit is upside.
- Prudent leverage. Non-recourse project debt layered in once scale and cash flows are proven — never to make the equity case.
Where we see the pattern
Bridging power that lets a site energise years ahead of its grid connection. Permanent microgrids serving data centers, campuses and industrial users that value resilience as much as cost. Distributed generation platforms that standardise the contract and the equipment across many sites. And the operating businesses — developers, integrators, service providers — that have the capability and the customers but not the balance sheet to grow at the speed of demand.
These are the businesses we want to talk to. See how we think about infrastructure growth equity, or get in touch.
