Your electricity bill isn't just a line item, it's a margin killer. And most of it is avoidable.
Indian manufacturers pay among the highest industrial tariffs in Asia. MSEDCL's HT-I tariff alone is INR 7.61/kWh base, but demand charges, wheeling, cross-subsidy surcharges, and fuel adjustment push effective costs to INR 8.5-10/kWh.
Maharashtra charges INR 230/kVA/month, Tamil Nadu INR 200/kVA/month, Karnataka INR 250/kVA/month. For a 500 kVA facility, demand charges alone add INR 1.0-1.25 lakh/month to the bill, 40-60% above energy charges.
Grid outages force reliance on diesel generators at INR 18-24/kWh, 2-3x grid rates. Add fuel logistics, maintenance, pollution compliance, and noise. A 250 kVA DG set consumes INR 4-6 lakh/month in diesel alone.
Rooftop solar generates peak power at noon, but production runs through evening shifts. Without storage, 30-40% of solar generation is exported at INR 2-3/kWh, a fraction of its self-consumption value of INR 8-10/kWh.
Each lever attacks a different part of your electricity cost structure. Combined, they deliver 30-40% bill reduction.
BESS monitors real-time load and pre-emptively discharges when demand approaches your set threshold. The utility meter never sees the peak. Works across MSEDCL, TANGEDCO, BESCOM, TPDDL, and all major DISCOMs.
Peak demand recorded; INR 1.15 lakh/month in demand charges (MSEDCL)
Peak shaved by 200 kVA; demand charges drop to INR 69,000/month
Maharashtra's MSEDCL offers 20% discount during 0900-1200 and 25% surcharge during 1800-2200. TANGEDCO has 6-hour peak windows with 20% surcharge. BESS charges during cheap hours and discharges during expensive ones, automatically, every single day.
Evening peak hours (1800-2200) at MSEDCL's 25% ToD surcharge
Charge during solar hours at 20% ToD discount; discharge at peak
A 200 kWp rooftop solar plant generates 800-900 kWh/day. Without storage, 250-350 kWh is exported at low net metering rates. With BESS, that energy is stored and consumed during evening shifts at its full avoided-cost value of INR 8-10/kWh.
Solar self-consumption; 30-40% exported at INR 2-3/kWh net metering rate
Excess solar stored for evening/night use at full self-consumption value
BESS provides instant backup (< 20ms switchover) versus 8-15 seconds for DG startup. No diesel procurement, no fuel theft risk, no emission compliance, no noise complaints from neighboring residential areas. Seamless coordination with existing DG for extended outages.
250 kVA DG: INR 4-6 lakh/month diesel + INR 50K maintenance
Zero fuel, zero maintenance, zero emissions, zero noise
A battery without intelligence is just a box. Ingro's software stack automates every savings decision, no manual intervention, no missed opportunities, no guesswork.
Monitors every individual battery cell across your BESS fleet, voltage, temperature, impedance, SoC. Predicts optimal charge/discharge windows based on tariff schedules, load forecasts, and battery health. All accessible from a single dashboard, anywhere.
Machine learning models ingest your DISCOM's ToD tariff structure, historical load patterns, weather forecasts, and production schedules to automatically determine when to charge, when to discharge, and how much. Adapts in real-time to schedule changes and tariff revisions.
ML-powered load forecasting predicts demand 15 minutes ahead with 95%+ accuracy. Pre-emptively discharges BESS to shave peaks before they hit the utility meter. Works within the 15-minute demand integration window used by Indian DISCOMs to calculate maximum demand.
Satellite-based irradiance forecasting combined with panel performance modeling predicts solar generation 24 hours ahead. The system decides in real-time: store in battery for evening self-consumption or export to grid, always maximizing the INR/kWh value of every unit generated.
During grid outages, BESS responds in under 20ms, eliminating the 8-15 second gap of DG startup. For extended outages, intelligent dispatch runs BESS first, starts DG only when battery SoC drops below threshold, and stops DG the moment grid returns. Eliminates unnecessary diesel runtime.
Real-time savings dashboard shows exactly how much BESS has saved this month, broken down by demand charge reduction, ToD arbitrage, solar optimization, and DG replacement. Monthly reports with ROI tracking, payback countdown, and carbon offset metrics.
Two identical 500 kWh battery systems can deliver vastly different savings depending on the intelligence layer. Without smart dispatch, you capture maybe 50-60% of the available savings. With Ingro's AI-driven EMS, you capture 90%+ because every charge/discharge decision is optimized in real-time against tariff rates, load forecasts, solar generation, and battery health. The software is what turns a “battery box” into an automated energy profit center.
Walk through the economics for a typical 500 kVA manufacturing facility on MSEDCL HT-I tariff in Maharashtra.
Peak reduced from 500 to 300 kVA
45% spread captured across 8 hours/day
Self-consumption increased from 65% to 92%
80% DG runtime eliminated
A structured process to right-size, install, and optimize your industrial BESS for maximum ROI.
We analyze 12 months of electricity bills, 15-minute interval load data, ToD tariff structures, DG run logs, and solar generation profiles. Every rupee of savings potential is quantified before a single battery is specified.
Our simulation engine models thousands of dispatch scenarios against your specific DISCOM tariff, load profile, and solar capacity. The output: optimally sized BESS with projected savings, payback, and IRR for your CFO.
Containerized BESS deployed on-site with seamless integration into existing HT/LT panels, solar inverters, and DG switchgear. Typical installation: 4-6 weeks with minimal production disruption.
AI-driven EMS takes over from day one, automatically optimizing dispatch across all four savings levers. Monthly reports track actual vs. projected savings. Scale capacity as your ROI compounds.
Share your last 3 electricity bills and we'll deliver a custom savings report showing exactly how much BESS can cut from your demand charges, ToD costs, diesel spend, and solar waste.
