Upload your site's load data and the system simulates daily BESS charge and discharge cycles to size the system around your maximum demand, then calculates payback period and annual bill savings. Export a client-ready proposal in one click.

Finding the best-value BESS size: capacity vs. investment return

Simulation results overview
1
Gather Your Load Data
Connect to your utility portal, upload 15-minute interval data, or link your site's meters for continuous data collection.
Add on: Smart Clamp Meter Kit
If there is no available data for the field, you can purchase an optional smart clamp meter toolkit.
The flexible clamp meter can be installed directly on existing lines, and once data is transmitted back to the cloud, a power consumption curve can be established. The clamp meter toolkit is optional, not a mandatory accessory of this product.

Set Up Your Simulation Scenario
Best Return
Enter your per-cabinet capacity and the system tests multiple system sizes to find the best-return combination.
Fixed Capacity
Already know your BESS capacity? Get the ROI and savings straight away.
Solar + BESS
Add PV generation to the simulation: charge your BESS from PV only, or SELCO and take advantage of ToU arbitrage.

3
Input Your Capex
Costs can be entered as construction unit price or total price, and support annual maintenance fees, extra fixed costs, and subsidies.
Energy storage parameters include round-trip efficiency (RTE), depth of discharge (DOD), and annual battery SOH degradation rate, etc.
Support loan calculations
Configure loan percentage, interest rate and tenure.

MD Optimisation Potential
Provides daily simulated charging and discharging results, allowing users to inspect day-by-day when to charge, when to discharge, how much peak load is reduced, and how much benefit is generated.

Built-in TNB Tariff
Time-of-use tariff periods and maximum demand billing logic are built into the system. Tariff updates are maintained for you, no spreadsheets to keep up.
Get the Tool, Not Just a Report
Your team runs the simulations itself, so there's no need to go back and request a study for each proposal.
If the site owner can't provide electricity data, start measuring with the optional Smart Clamp Meter Kit and fill the data gap that most often holds up proposals.
