Your factory pays ₹15 crore annually to the grid.
Build a captive solar plant. ₹100 crore capex. Eliminate the power bill.
Own your infrastructure. Control your costs. Never pay grid tariffs again.
The captive power advantage
Dedicated Plant = You Own Everything
Not a PPA where you rent power. Your solar plant. Your plant battery. Your electricity.
What You Own:
- Solar panels and inverters
- Plant-side BESS (evening delivery, curtailment avoidance, GRIDCO compliance)
- Transmission infrastructure
- Control systems
- All generation capacity
What You Save:
- Zero power purchase costs
- No wheeling charges
- No cross-subsidy surcharges
- No distribution losses
- No grid dependency
- Plant BESS extends solar into evening — fewer grid-dependent hours
Want on-site backup? Add our Reliability tier — on-site BESS at your facility for instant switchover and demand charge elimination.

The captive reality
You're paying ₹15 crore/year to the grid. Forever.
Grid tariffs will rise 8% annually. In 10 years, you're paying ₹32 crore/year.
Or build captive. ₹100 crore once. ₹1.5 crore/year O&M. Power bill eliminated.
After 7 years, the plant is paid off. Years 8-25 are pure savings.
₹14.25 crore/year × 18 years = ₹256 crore in post-payback savings.
Plus you own a ₹100 crore power plant.
For 20+ MW industrial facilities in Odisha.
For steel, cement, aluminum, chemical plants.
For CFOs tired of grid dependency and escalating tariffs.
We build turnkey dedicated solar + plant BESS plants. Complete EPC + 25-year O&M. You own everything. 6-month delivery. Add Reliability tier for on-site backup at your facility.
