Peak shaving
Discharge during the intervals that set billing demand, within rated power and available energy.
BESS Engineering
Dispatch logic engineered around your real load profile.
A BESS does not remove demand from a facility. It is a controllable asset that can reduce grid draw during targeted periods, depending on tariff, load profile and project design.

Curves are illustrative. Actual behavior depends on the utility tariff, 12 months of interval data, interconnection, equipment selection, dispatch strategy and operating constraints.
Applications
What storage is engineered to do.
Load shifting
Move stored energy into higher-cost periods defined by the tariff and operating schedule.
Demand-charge management
Target the specific charge components the rate actually bills, including ratchets where present.
Demand response
Participate where the facility and asset are eligible and the operating plan allows it.
Resilience where designed
Backup capability depends on topology, transfer equipment and the loads selected for support.
Solar time-shifting
Store on-site generation rather than exporting it at low value, when that improves economics.
Tariff optimization
Test dispatch logic against alternative rate structures available to the account.
Capacity planning
Use storage and controls to manage headroom when new load is added to an existing service.
Project economics depend on the utility tariff, interval load data, interconnection, equipment selection, dispatch strategy and operating constraints. No savings figure should be assumed before those are reviewed.

FAQ
Technical questions, answered carefully.
- What is BESS?
- A battery energy storage system is a controllable electrical asset — batteries, power conversion, protection and controls — installed at a facility and dispatched according to defined logic. It stores energy and releases it at chosen times, within its power (kW) and capacity (kWh) limits.
- How can BESS affect peak demand and demand charges?
- When it discharges during an interval that would otherwise set billing demand, the meter records a lower facility draw for that interval. Whether that translates into a lower bill depends on the tariff structure, how demand is measured, the accuracy of dispatch and the facility's load profile. Storage is not the only way to influence demand, and it is not always the most effective one.
- Is the site assessment really free?
- The preliminary onsite assessment is offered at no cost for qualified commercial and industrial opportunities. Qualification depends on facility type, load size and data availability.
- Why typically three days onsite?
- Measurement takes time. Roughly one day for electrical mapping and baseline, one for instrumented measurement and thermography, and one for validation with your team and feasibility review. Larger or more complex sites can take longer.
- Do I need solar?
- No. Solar is complementary. We integrate it when it improves charging strategy or project economics, and we say so when it does not.
- Can you finance the system?
- We can help structure project or equipment financing through financing partners. Any financing remains subject to underwriting, credit approval, lender terms and project economics. We do not approve or guarantee financing.
- Are incentives guaranteed?
- No. We screen for potential eligibility under programs that may apply to your account. Program availability, rules and eligibility can change, and approval is always decided by the program administrator.
- What data is needed?
- Ideally twelve months of utility bills and interval or load data, plus the operating schedule, single-line drawings where available, and access to electrical rooms during the site visit.
- Can BESS provide backup power?
- Only if the system is specifically designed for it. Backup requires appropriate topology, transfer equipment, protection and a defined set of loads, and it affects sizing and cost.
