Commercial and Industrial Peak Shaving Solution

Overview

Commercial and Industrial Peak Shaving Solution

Commercial and industrial electricity users face two separate cost problems: the energy tariff, which rewards shifting consumption to off-peak hours, and the demand charge, which penalises the highest fifteen- or thirty-minute interval of the month. A battery energy storage system addresses both by charging when power is cheap and discharging when it is expensive or when site load peaks. In markets with unstable supply, the same system also covers short outages and protects production lines from interruption. EcoDyny supplies cabinet and containerised BESS from 100 kWh to 500 kWh with integrated PCS, BMS and energy management, quoted per project on load data and tariff structure.

Part 01

Tariff Arbitrage and Demand Charge Reduction

Two value streams usually justify a C and I battery: the spread between peak and off-peak energy prices, and the reduction of monthly maximum demand.

Charge during off-peak or valley tariff windows, discharge during peak windows, once or twice per day
Peak-shaving logic that trims site load above a configurable threshold rather than following a fixed schedule
Typical daily cycling of one to two cycles, aligned with the site's operating hours
Demand-limiting setpoint configured per month and adjusted seasonally
Energy management controller that can run arbitrage, peak shaving or a blended strategy

We provide the load-data template we use for sizing, so the business case is built on the site's own interval meter data rather than generic assumptions. Battery power rating is sized on the site's load peaks rather than on average consumption, because the value of the system is concentrated in a small number of high-demand intervals each month.

Part 02

Load-Shedding Resilience and Backup Function

In parts of Africa, South Asia and the Middle East, grid instability is a first-order concern rather than a secondary benefit. A storage system designed only for arbitrage is often unsuited to backup duty, so the two functions must be reconciled at design stage.

Automatic transfer to backup mode on grid loss, with defined transition time and protected load circuits
Reserve state-of-charge floor held back for outage coverage instead of being sold into the peak window
Protected-load design so refrigeration, servers or critical process equipment stay energised while non-essential loads drop
Sizing based on the longest expected outage and the critical load, not the whole site load
Optional diesel or solar integration as a second layer where outages are long and frequent

Where backup and arbitrage share the same battery, we document the reserve policy explicitly so daily dispatch does not erode outage autonomy.

Part 03

System Integration and Safety

C and I installations sit inside working facilities, so safety engineering and physical integration matter as much as energy capacity.

All-in-one cabinet or containerised designs with integrated PCS, BMS, HVAC and fire suppression provisions
Multi-level protection: cell monitoring, pack fuses, contactor control, insulation monitoring and arc detection options
Thermal management by forced-air or liquid cooling depending on climate and duty cycle
Grid-code and anti-islanding functions configured per destination market
Parallel expansion of multiple units to reach larger capacities without replacing installed equipment

We supply layout drawings, cable schedules, earthing recommendations and commissioning procedures, and we can review your site's single-line diagram before finalising the configuration. Where site space is limited, cabinet units can be installed indoors against a wall with defined clearance, while containerised units suit yards and loading areas with road access for delivery and servicing.

Benefits

What this design gives you

Two Revenue Streams

Energy arbitrage and demand charge reduction can be captured from the same asset, improving payback relative to a single-purpose installation and diversifying the project's revenue base.

Production Continuity

Backup-capable configurations keep critical loads energised through grid disturbances, protecting work in progress, refrigeration and temperature-sensitive stock from spoilage, rework and unplanned restart costs that would otherwise be absorbed by the operator.

Documented Reserve Policy

Where one battery serves both arbitrage and backup, the reserve state of charge is defined in writing so outage autonomy is not quietly traded away during daily dispatch optimisation.

Sized on Real Meter Data

Sizing uses the site's own interval load data and tariff schedule, so capacity, power rating and payback estimates reflect actual consumption patterns rather than generic industry assumptions or vendor averages.

Modular Expansion

Additional cabinets or containers can be paralleled as load grows, allowing phased investment instead of committing the full project capacity at the outset and spreading capital expenditure across budget cycles.

Project-Level Engineering Support

Single-line diagram review, layout drawings and commissioning procedures are provided so local contractors can install and test to a defined standard without factory supervision on site.
