Commercial Building ESS Deployment
A behind-the-meter battery storage scenario for offices, retail, and mixed-use buildings — cutting demand charges and adding backup without disrupting day-to-day operations.
01Project Background
Commercial Building ESS
Commercial buildings carry energy costs and resilience risk that storage addresses directly. This scenario shows how a behind-the-meter system is specified for a typical occupied building.
This is a generic engineering deployment scenario used to illustrate system design — it is not a specific customer installation.
02Customer Challenge
Site challenge
A typical commercial building faces recurring cost and reliability pressure:
- Demand charges can represent 30–50% of a commercial utility bill, triggered by short peak intervals.
- Outages disrupt business, spoil inventory, and create safety risks in occupied buildings.
- Rooftop PV without storage exports cheap daytime energy yet still draws heavily from the grid at night.
- ESG and resilience mandates now require measurable, auditable energy performance.
03Solution Overview
Solution approach
A behind-the-meter cabinet couples to the building distribution panel, charges from solar or off-peak grid, and discharges during peak tariff windows and outages.
04System Architecture
Typical Commercial Building ESS topology
A grid-connected PCS couples the battery cabinet to the building distribution, accepts PV input, and can supply EV charging without a service upgrade.

09FAQ
Frequently Asked Questions
Do I need to rewire my building?
No. Storage connects at the main distribution panel; existing circuits are protected, not replaced.
Will it back up the whole building?
Critical loads are prioritized automatically; full-building backup is sized on request.
Can it work with my existing solar?
Yes. Every solution accepts PV input and retrofits to existing arrays.
