What we deliver

Our Battery Energy Storage Systems capabilities

Demand Charge Management

Battery storage systems discharge during peak demand windows to shave the demand spikes that drive 30–50% of commercial utility bills. We model your load profile to right-size the battery for maximum bill reduction.

Backup Power & Resilience

Seamless backup power for critical loads during outages. Systems configured for automatic island-mode operation — no manual intervention required when grid power fails.

Solar+Storage Integration

Battery systems co-located with solar PV maximize self-consumption, shift production to peak price periods, and provide backup power when neither grid nor sun is available.

Who we serve

Ideal for these applications

High Demand Charge Customers

Manufacturers, cold storage facilities, and EV charging operators where demand charges dominate the utility bill — battery storage typically reduces bills by 15–35%.

Critical Facilities

Data centers, medical facilities, and emergency services where grid outages are unacceptable — battery storage bridges the gap until generator start or extends run time for critical loads.

Microgrids

Campuses, industrial parks, and municipal facilities creating energy-independent microgrids combining solar, storage, and generator assets.

Commercial Solar Owners

Existing solar PV owners looking to add battery storage to maximize self-consumption, avoid export curtailment, and gain backup capability.

How it works

Our battery energy storage systems process

Load & Tariff Analysis

Utility bill review, demand charge history, time-of-use rate analysis, and load profile assessment to determine optimal battery size and operating strategy.

System Design

Battery selection, inverter sizing, integration with existing solar or generator systems, and safety system design — submitted for utility and AHJ review.

Installation

Battery enclosure placement and anchoring, electrical interconnection, safety disconnect installation, and controls wiring by our licensed electrical crews.

Commissioning & Optimization

System start-up, operating mode programming (demand response, backup, arbitrage, or combined), monitoring platform activated, and performance verified against financial model.

Common questions

Frequently asked

What battery chemistry do you install?

We primarily install lithium iron phosphate (LFP) systems for commercial applications due to their superior thermal stability, long cycle life (4,000+ cycles), and UL 9540 compliance. We work with Generac PWRcell, Stem Athena, and Tesla Megapack for commercial scale.

Is battery storage eligible for the federal investment tax credit?

Standalone battery storage became eligible for the 30% federal ITC under the Inflation Reduction Act. Battery systems co-located with solar may be eligible for additional incentives. We can help identify applicable credits.

How long will the batteries last?

Commercial LFP batteries are typically warranted for 10 years at 80% capacity retention. Real-world life is often 15–20 years at moderate cycling rates.
