Lower commercial electricity costs without buying a battery.
Stack Power is developing a model to finance, deploy, and operate behind-the-meter battery storage for qualifying commercial facilities—aligning project economics with verified performance while reducing the customer's upfront capital requirement.
Currently developing our first South Florida commercial pilot.

The problem
Commercial power costs aren’t just about how much electricity you use.
Depending on the utility tariff, part of a commercial bill may be tied to the facility’s highest level of demand during a relatively short interval.
A facility can operate normally for most of the month and still experience a material demand spike when large electrical loads overlap. Potential sources include:
If multiple large loads run simultaneously, reducing the peak may have economic value. The answer is facility- and tariff-specific; not every FPL commercial account will support attractive storage economics.
Illustrative example
The Stack Power model
Storage without the traditional upfront investment
Stack Power is developing a performance-aligned project structure for qualifying commercial facilities. The customer can participate in the operating benefit of storage without purchasing the entire system upfront.

How it works
A project-development process built around evidence
Every stage increases confidence before capital is committed. Screening is not treated as engineering, and modeled results are not treated as measured performance.
- 01
Analyze
Review utility bills, tariff information, interval usage, facility characteristics, and major electrical loads.
- 02
Model
Simulate battery power and energy configurations to determine whether storage appears economically attractive.
- 03
Validate
Work with qualified technical partners to test real equipment, site conditions, warranties, installation scope, and project costs.
- 04
Finance & deploy
For qualifying projects, arrange financing while licensed engineering and installation partners execute the electrical work.
- 05
Operate
Control the BESS to reduce supported electricity costs within equipment, warranty, site, and agreed operating constraints.
- 06
Measure & share
Use actual operating data to measure performance and determine verified savings under the final customer agreement.
Battery operation
Charge when capacity is available. Discharge when the building needs it most.
A behind-the-meter BESS can charge during a suitable period, then supply part of the building's demand during an expensive peak. The dispatch strategy must preserve operational priorities and respect real equipment constraints.
Illustrative daily operation
Charging and discharging must be scheduled around the facility, tariff, equipment limits, and future operating needs.
No customer data
POWER · kW
How much demand can be offset at one moment?
Power determines the instantaneous portion of building demand the battery may serve.
ENERGY · kWh
How long can the battery sustain that output?
Energy capacity determines whether the system can cover the real duration and recurrence of a facility's peaks.
Project discipline
The battery is only one part of the project.
Commercial storage succeeds only when the technical, operational, contractual, and financial variables work together.
The objective is not to sell a battery. The objective is to determine whether a battery is a good investment for a specific facility.

Potential customer profiles
Where storage may make sense
Stack Power is initially studying energy-intensive commercial facilities in South Florida. These categories are potential candidates—not a claim that every site has attractive economics.
Customer value
Infrastructure designed around customer outcomes
Lower electricity costs
Battery operation may reduce expensive peak demand and other supported utility costs.
Reduced upfront capital burden
Qualifying projects may be financed instead of requiring the customer to purchase the complete system upfront.
Performance alignment
The intended commercial structure links project economics to measured system performance.
Long-term operations
Stack Power intends to monitor savings, degradation, availability, and maintenance throughout the project life.
Optional resilience
Some projects may support critical loads during outages, depending on equipment and final electrical design.
Future platform
Software built around the physical asset
Stack Power is developing software to support project origination, underwriting, measurement, and long-term operations. The software serves the infrastructure business; it is not the product on its own.
Hardware integration and customer telemetry will be introduced only after a real OEM and energy-management system are selected.

01
One project first
Our initial focus
Starting with South Florida
Stack Power’s initial focus is commercial facilities served by Florida Power & Light in South Florida. The goal is to validate one project end-to-end before scaling.
One project first. Scale only after the economics are proven.
Current stage
Building the first project
Stack Power is currently validating the model and assembling the commercial, technical, project-development, and financing relationships required to deliver the first pilot responsibly.
If your organization works on commercial battery storage, distributed energy, project finance, or commercial electrical infrastructure, we would be interested in speaking.

Frequently asked questions
Does Stack Power install batteries?
Stack Power is developing and originating commercial storage projects. Final engineering, permitting, electrical installation, and commissioning are expected to be performed by appropriately qualified and licensed technical partners.
Does the customer have to buy the battery?
The intended model is to provide qualifying projects through project financing so the customer does not need to make the full upfront battery investment. Final commercial terms depend on project underwriting and financing.
How are savings calculated?
Projects require actual utility and interval-consumption data. Savings are modeled using the applicable utility structure, battery operating behavior, and project assumptions, then measured after installation according to the final contractual methodology.
Will every commercial property save money?
No. Stack Power’s analysis is intended to reject projects where storage does not produce compelling economics.
Can the battery provide backup power?
Potentially. Backup capability requires additional equipment and electrical design and must be evaluated separately for each facility.
Can the battery sell electricity back to the grid?
Potential utility, demand-response, grid-service, or export opportunities depend on applicable programs, interconnection requirements, and contracts. Stack Power does not currently assume speculative grid revenue when evaluating initial projects.
Where is Stack Power operating?
Stack Power is initially focused on validating its first commercial project in South Florida.

Website information and diagrams are preliminary and informational. Site-specific economics require verified utility data, tariff review, interval analysis, current equipment pricing, engineering, and site evaluation. Stack Power does not guarantee savings shown in illustrative examples. Electrical engineering, design, permitting, and installation must be performed by appropriately qualified professionals. Financing is subject to underwriting and availability; tax incentives are subject to eligibility. Grid-service, utility-program, demand-response, VPP, and export opportunities are not guaranteed or included in base economics unless specifically verified and contracted.
