How Grid + BESS Powers Your Facility
The grid charges it. VoltSeal stores it. Your facility uses it no diesel required.
The VoltSeal lithium ion BESS charges from the grid during off-peak hours when electricity rates are at their lowest. That stored energy is then discharged to power your facility when you need it most during peak hours, grid outages, or when your DG would normally kick in.
When the grid goes down, this BESS for warehouses and industrial facilities automatically supplies power in under 200ms. No startup lag. No fuel. No noise.
The result is a reliable backup power system that replaces your DG entirely, reduces your energy costs significantly, and keeps your facility running continuously — with no solar infrastructure required.
What Grid + BESS Actually Costs vs Your DG
Grid power at off-peak rates costs a fraction of diesel. VoltSeal stores it so you can use it anytime.
Running a diesel generator costs ₹32–35 per unit of electricity. With a Grid + BESS for warehouses and industrial facilities, you charge the VoltSeal lithium ion battery system from the grid at off-peak rates and discharge it when you need it most. The result is stored energy at ₹6-8 per unit on average less than a third of what your DG costs per unit.
For a 500kW operation running 4 hours a day, 250 days a year, that translates to an annual saving of up to ₹52L, with a payback period of 3-4 years. Replacing your DG with a lithium ion battery backup power system means your warehouse energy cost reduction compounds every year. Over 10 years, the cumulative advantage crosses ₹12–14 Cr.
And the gap is only growing. Diesel prices have risen significantly over the last three years and CPCB IV+ compliance norms have added another 15–20% to DG operating costs. Every year you continue running a DG, the cost compounds.
Grid + BESS costs stay flat. Your DG costs do not.
GRAP Season Arrives Every Year. Your DG gets banned.
Grid + BESS keeps your facility running even when your DG legally cannot.
The Graded Response Action Plan (GRAP) comes into effect across Delhi NCR every year, typically between October and February. As air quality deteriorates through the stages, restrictions on diesel generator usage become progressively stricter. At Stage 3 and Stage 4, the GRAP generator ban makes DG usage illegal outright.
For facilities that rely on DG as their backup power source, this creates a period of genuine operational uncertainty every winter.
A Grid + BESS removes that uncertainty entirely. The VoltSeal lithium ion battery system charges from the grid and discharges when needed, with no diesel involved at any point. GRAP restrictions simply do not apply. Your facility continues to operate normally regardless of the air quality stage in effect.
