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

What We Do

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 commitment 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.
