Buy Clean Solar Power Directly,
Cut Heavy Industrial Tariffs by 30%–50%
Off-site solar power wheeling and long-term Power Purchase Agreements (PPA) for High-Tension (HT) commercial and industrial consumers in Tamil Nadu & South India. Zero upfront capital expenditure with 100% regulatory compliance.
Demystifying Solar Open Access & Power Purchase Agreements
If your facility has high electricity consumption but limited or unviable roof space, off-site Open Access solar power wheeling lets you purchase clean solar energy generated at a utility park directly through the grid.
The Open Access Framework
Open Access is the regulatory framework (Electricity Act 2003 & Green Energy Open Access Rules) enabling HT consumers to procure electricity directly from independent renewable power producers using the state transmission (TANTRANSCO) and distribution (TANGEDCO) grid networks.

- check_circle Lowered threshold to 100 kW under Green Energy Open Access (GEOA)
- check_circle Direct grid credit adjustment against monthly DISCOM HT consumption bills
Power Purchase Agreement (PPA)
A Power Purchase Agreement (PPA) is a bilateral, legally binding contract between the power consumer (you) and the power developer (SolarQube / IPP) establishing a fixed, discounted unit tariff (₹/kWh) for solar power supplied over an agreed term of 10 to 25 years.
- check_circle Zero Capital Expenditure: The solar developer finances, builds, and operates the plant
- check_circle Inflation-Proof Energy Rates: Protect your operations against frequent DISCOM tariff hikes
- check_circle Pay-As-You-Consume: Pay strictly for the actual clean units generated and wheeled
Choose the Optimal Open Access Solar Model
Depending on your energy volume, legal structure, and equity preference, SolarQube structures tailored off-site and on-site procurement contracts.
Group Captive Model
26% Equity • 51% Consumption Rule
The power buyer holds a minimum 26% equity stake in the Special Purpose Vehicle (SPV) power plant and consumes 51% of generated power. Crucial Benefit: 100% exemption from Cross-Subsidy Surcharge (CSS) and Additional Surcharge (AS).
Third-Party Open Access
Zero Equity • 100% Bilateral PPA
Pure zero-equity power purchase contract between the industrial consumer and an off-site solar IPP developer. The buyer pays for delivered power plus applicable DISCOM wheeling and cross-subsidy surcharges.
On-Site RESCO / OPEX
Rooftop Solar • Investor Funded
SolarQube installs and maintains the solar system directly on your factory or warehouse roof with zero CAPEX investment from your business. You purchase the generated power at a heavily discounted per-unit rate.
Real Impact on Your Monthly HT Electricity Bill
Industrial electricity tariffs from state DISCOMs (TANGEDCO HT Tariff IA / IIA) average ₹8.50 to ₹10.50 per unit including peak TOD charges and electricity tax. By wheeling solar power via Group Captive Open Access, your landing cost drops to ~₹4.80 to ₹5.50 per unit.
