Utility-scale generation
Power plants for industry, developments and the grid
GIS Power develops, finances, builds and operates industrial and utility-scale power plants. Primary power is solar with battery storage (BESS); gas, engines and the grid come in where the site needs firm capacity, backup or power at night.
Solar and BESS first
Everything else where it is neededA large plant is designed from the load: how much the site consumes, at what time, how continuous supply must be and what an outage costs. That curve sizes the solar generation, the storage that shifts it to the hours without sun, and the backup that makes it firm.
Where the load cannot be interrupted or the solar resource falls short, the plant becomes a hybrid: engines on natural gas or biogas, and the grid where it exists. Where there is also a heat or cooling demand, cogeneration puts the engine’s heat to use.
Each project sits in its own special purpose vehicle (SPV), which raises the financing, owns the plant and sells the energy or the service to the user under a 48 to 180 month contract.
When it is not a fit
- If your demand is smaller and steady, and the site’s grid supply covers it comfortably at a good price.
- If there is no land, roof or nearby site for the solar generation the load requires.
- If your operation at the site may end before the energy contract term.

From feasibility to operation
One party accountable at every stageThe project moves in stages, and each one leaves something a lender can review: an energy balance, a permitting path, a contract and a plant with contracted availability.
- Feasibility
Load curve, solar resource, land, interconnection and financial model.
- Development
Permits with the CNE, studies with CENACE, gas supply where needed and the energy contract.
- Finance
SPV, equity and debt, with the energy contract as the source of repayment.
- Engineering and construction
EPC with brand-authorized commercial partners: INNIO Jenbacher, Guascor, Pylontech and Huawei.
- Operation
24/7 operation and maintenance with contracted availability.

Frequently asked questions
Why solar and BESS as primary power?
Because solar power does not depend on a fuel price, and storage delivers it when the site needs it. Gas and the grid cover what solar cannot: long nights, cloudy days and the firmness a critical load requires.
Does the plant have to be on my property?
Not always. Generation can be on site or at a remote location, depending on the land, the interconnection and the permitting route that applies to the project.
Who invests in the plant?
Either an SPV invests and sells you the energy or the service, or your company invests through a lease, a loan or cash. Contract terms run from 48 to 180 months, depending on the scheme.
