What We Do

our partners

Who We Work With

Liminal partners with developers and capital providers across all phases of the energy storage project lifecycle.

Developers

We enable projects and their owners’ long-term success by providing development services and capital tailored to the unique needs of each situation.

Capital Providers

We help project investors improve returns by leveraging our experience to optimize projects and co-invest alongside to ensure long-term alignment

We develop, acquire, finance, own, and operate profitable energy storage projects. As both owners and investors, we deploy capital with long-term performance in mind—bringing tailored solutions that reflect the unique realities of each project rather than a one-size-fits-all model

How We Invest & Execute

We solve the hard problems in energy storage by combining technical, financial, and operational expertise into one accountable partner.

For the projects we invest in, we take on that role by integrating execution and capital across development and operations, with capital deployed through development-stage investments, common equity, and preferred equity. By aligning decision-making from the start, we deliver tailored solutions designed for lasting asset performance.
‍
We believe in transparency and continuous accountability, and shared outcomes in everything we do. That shows up in our:

Consistency

Consistent follow-through

Alignment

Aligned investment and shared outcomes

Trust

Responsible stewardship of our stakeholders’ trust

Transparency

Transparent decision-making

Our Integrated Model

Liminal prioritizes long-term performance over competing priorities, which helps us turn models into projects that perform in the real world.

The Energy Storage Opportunity

Energy Storage is a critical and rapidly growing asset class. Opportunities for long-term growth are driven by:

Rapidly increasing load growth driven by data center/AI demand and electrification of industry will stress the grid and require dispatchable assets like energy storage to provide needed capacity

Growing penetration of renewable energy on the grid, and the increasing intermittency of supply, results in lost energy and arbitrage opportunities for energy storage

Energy storage costs have decreased dramatically over the past decade and will continue to drop, increasing the number of investable projects

FAQ

Do you invest alongside partners?

Yes. We co-invest where appropriate and remain involved through operations to ensure aligned outcomes..

Where do you typically get involved in a project?

We engage from early evaluation through execution and long-term operations, depending on project needs.

Do you replace developers or EPCs?

No. We work alongside partners to integrate decision-making and execution—not displace existing teams.

What markets do you focus on?

U.S. grid-scale energy storage, with a focus on projects requiring disciplined execution and long-term performance.
