Open Access allows industrial and commercial (C&I) consumers to buy electricity directly from private renewable power producers instead of relying solely on the state distribution company (DISCOM) supply. This helps businesses access lower electricity tariffs and clean energy by utilizing the existing grid transmission network.
Savings depend heavily on your specific state, your current tariff structure, and the power procurement model chosen. However, most industries experience a 15% to 40% reduction in their net energy costs compared to traditional utility tariffs.
Choosing the right model depends on your budget and how much risk you want to take on. Here is how they stack up side-by-side:
| Model | Ownership Required | Upfront Investment (CapEx) | CSS (Cross-Subsidy Surcharge) Exemption | Ideal For |
| Captive | ≥26% equity | Yes | Yes (Maximum savings) | Very large power consumers |
| Group Captive | ≥26% equity shared among a group | Yes | Yes | Medium and multi-unit loads |
| Third-Party Sale | None | No | No (Subject to surcharges) | Fast adoption & zero-CapEx preference |
Yes. Facilities with a minimum connected load of 1 MW qualify for most Open Access models across India. For businesses with smaller loads, we can explore group allocation opportunities or specific hybrid models depending on your state’s regulations.
No. Under the Group Captive and Third-Party Sale models, your power is generated at offsite, utility-scale solar or wind farms and delivered to your facility via the state grid. No space is required at your actual corporate location.
Businesses can choose from solar, wind, small hydro, or hybrid (solar + wind + storage) solutions. Your choice will depend on local resource availability, cost advantages, and your specific daily load profile.
Yes. Open Access power runs parallel to your existing grid supply. The system includes strict scheduling, forecasting, and backup protocols managed by the State Load Despatch Centre (SLDC) to ensure highly reliable, uninterrupted power delivery.
No major infrastructure changes are required. Power is delivered using your existing grid connection lines. The Open Access system runs seamlessly alongside your current DISCOM supply with zero operational downtime during transition.
Banking acts like an energy savings account. It allows your business to store surplus renewable energy generated during low-demand periods (like Sundays or afternoon peak generation hours) and draw it back from the grid later when your demand increases. This helps balance seasonal and daily variations.
Consumers receive two separate bills:
Open Access agreements offer flexible scheduling frameworks. This allows your business to purchase power in alignment with your actual seasonal or operational consumption patterns to ensure your costs remain optimized.
Key regulatory approvals typically include:
Open Access permissions/noc from utilities
Wheeling & Banking Agreements (WBA)
SLDC registration for power scheduling
Special energy metering and accounting setups
Power Purchase Agreement (PPA) documentation
Our team manages this regulatory process completely end-to-end.
The entire implementation process usually takes 8 to 16 weeks. This timeline is determined by state-specific regulatory clearing speeds, DISCOM approval times, and overall project readiness.
While a vast majority of Indian states offer Open Access frameworks, the associated charges, cross-subsidy surcharges, and banking policies vary significantly from state to state. We provide customized, state-specific advisory based on your load profile and local regulations.
Yes. Depending on your state’s specific electricity regulations, power can be “wheeled” (transmitted) across multiple operational units belonging to the same corporate entity, provided they are within the same state grid.
Most long-term power purchase agreements (PPAs) range from 3 to 15 years, which locks in low energy rates and gives your business predictable financial planning. However, medium and short-term options are also available depending on your risk profile.
