Wheel solar from Bhadla, Pavagada, Khavda, Mandsaur, Anantapur, Tirunelveli direct to your factory at ₹3.20-3.85/kWh landed — vs grid HT-I of ₹7.50-9.50/kWh. Group captive structuring with 26%+ equity captures cross-subsidy waivers.
Most state net metering caps top out at 1 MW per HT consumer (UP and MP allow 2 MW). For consumers with 5+ MW load, open access is the only practical route to renewable share above 25-30%.
Open access also wins for buyers without sufficient roof area: data centres, urban offices, multi-storey commercial, BFSI HQs, and industrial parks where on-site solar can't scale.
Scale: 5-200 MW per offtake — far beyond rooftop net metering
Off-site siting: no rooftop or industrial land required
Best per-kWh cost in many states (₹3.20-3.85/kWh landed)
Hourly time-block matching for 24×7 carbon-free energy targets
ESG cascade compliance for hyperscaler / OEM supply chains
Avoid Maharashtra BESS mandate by wheeling from outside the state
We structure the 26%+ equity stake in a solar SPV that owns the off-site plant — qualifying you for cross-subsidy waivers and wheeling concessions.
Direct relationships with developers at Bhadla (Rajasthan), Pavagada (Karnataka), Khavda (Gujarat), Mandsaur (MP), Anantapur (AP), Tirunelveli (TN).
Open access No-Objection Certificate, scheduling and despatch coordination with state SLDC, banking and curtailment management.
State-specific cross-subsidy surcharge waivers (50-75% in TN, AP, Telangana, Karnataka, UP, HP, Uttarakhand). Wheeling charge optimisation.
PVsyst yield modelling matched against your hourly load curve; monthly settlement reconciliation against PPA tariff.
RECs (Renewable Energy Certificates), 24×7 carbon-free energy matching, and Scope 2 emission documentation for parent ESG reports and OEM cascade compliance.
CSS waivers, wheeling charges, and solar park access vary materially by state. Pick the source park that matches your consumer state.
| State | CSS Waiver | Wheeling | Landed Cost | Source Park |
|---|---|---|---|---|
| Tamil Nadu (TANGEDCO) | 75% / 5 years | ₹1.30/kWh | ₹3.30-3.85/kWh | Tirunelveli |
| Andhra Pradesh (APSPDCL/EPDCL) | 50% / 5 years + 7-year duty exemption | ₹1.10-1.40/kWh | ₹3.20-3.65/kWh | Anantapur, Kurnool |
| Karnataka (BESCOM/MESCOM) | 75% / 5 years | ₹1.10/kWh | ₹3.20-3.65/kWh | Pavagada (2,050 MW) |
| Telangana (TSSPDCL/NPDCL) | 50% / 5 years + 20% BESS subsidy | ₹1.05/kWh | ₹3.30-3.70/kWh | Mahbubnagar, Adilabad |
| Gujarat (DGVCL/UGVCL/MGVCL) | 50% / 5 years | ₹1.00/kWh (lowest) | ₹3.20-3.65/kWh | Khavda RE Park (30 GW) |
| Rajasthan (AVVNL/JdVVNL/JpVVNL) | 50% / 5 years | ₹1.40/kWh | ₹3.20-3.60/kWh | Bhadla (2,250 MW) |
| Uttar Pradesh (PVVNL/MVVNL/PuVVNL/DVVNL) | 75% / 5 years | ₹1.30/kWh | ₹3.40-3.85/kWh | Bundelkhand (Jhansi-Lalitpur) |
| Madhya Pradesh (MPPKVVCL/MPMKVVCL/MPPoKVVCL) | 60% / 5 years + 5% loan subvention | ₹1.20/kWh | ₹3.30-3.75/kWh | Mandsaur, Neemuch, Rewa |
Confirm your sanctioned load > 1 MW + DISCOM open access NOC eligibility + state-specific cross-subsidy waiver applicability.
Match your hourly load profile to available capacity at Bhadla, Pavagada, Khavda, Mandsaur, Anantapur, or Tirunelveli.
For group captive, you (or a consortium) hold 26%+ equity in the project SPV. We handle cap table, SHA, and lender consent.
25-year (or shorter) PPA at locked-in tariff. Open access wheeling agreement with state transmission utility + DISCOM.
Off-site plant energises; monthly settlement reconciliation between scheduled and actual generation, wheeling charges, banking adjustments.
Open access solar lets large industrial consumers (>1 MW load) procure solar electricity from off-site plants via the existing grid — paying wheeling charges to the transmission utility plus a tariff to the solar generator. It's structured as third-party open access (you sign a PPA with a private developer) or group captive (you hold 26%+ equity in the project SPV). Best for buyers with limited rooftop area or those needing >1 MW renewable share.
Third-party open access: you sign a PPA with a private solar developer; the developer wheels electricity to you; you pay wheeling charges + cross-subsidy surcharge (CSS) at full rates. Group captive: you (or a consortium) hold 26%+ equity in the SPV that owns the solar plant. Group captive qualifies for state-specific CSS waivers (50-75% in major states) — making it materially cheaper for renewable share above 30%.
Landed cost is typically ₹3.20-3.85/kWh after wheeling, banking, and CSS adjustments — vs grid HT-I tariffs of ₹7.50-9.50/kWh. Variation by state: Gujarat (lowest wheeling at ₹1.00/kWh + Khavda access) and AP (7-year duty exemption stack) deliver the most aggressive economics. UP's 75% CSS waiver is also exceptional.
26%+ equity in the project SPV — typically ₹0.90-1.10 Cr per MW of group captive capacity. Sun Wave structures consortium SPVs where multiple consumers pool the 26% equity, dividing equity proportionate to their offtake. Most consumers contribute via balance sheet equity; some do via NBFC-financed equity contribution.
Partly. The April 2026 Maharashtra storage mandate applies to new captive plants commissioned within Maharashtra above 100 kW. Solar wheeled in from outside Maharashtra (e.g., Karnataka Pavagada, Gujarat Khavda) avoids the BESS mandate. New captive plants commissioned within Maharashtra under group captive must include the mandatory 50% / 2-hour BESS.
6-12 months end-to-end: 2-3 months for SPV structuring + PPA negotiation, 3-6 months for solar park EPC + commissioning, 1-2 months for open access NOC + wheeling agreement + scheduling onboarding with state SLDC. Group captive structures with new capacity take longer than third-party access to existing operational plants.
