Definition
Open Access is the regulatory framework in India that allows large electricity consumers (typically > 1 MW connected load) to procure electricity directly from generators (including renewable producers) using the existing transmission and distribution network, paying wheeling, banking, and other charges to DISCOMs.
Key Takeaways
- Open Access = direct power procurement framework for large consumers.
- Typical threshold > 1 MW connected load.
- Solar Open Access locks in low tariffs from third-party generators.
- Wheeling + banking + cross-subsidy charges apply.
- State-specific rules; varies significantly across India.
Frequently Asked Questions
4 commonly searched questions about Open Access (India).
What is Open Access?
Regulatory framework allowing large consumers (typically > 1 MW load) to buy power directly from generators using existing transmission/distribution infrastructure. DISCOM charges wheeling fees.
Why use Open Access for solar?
Avoids expensive DISCOM retail tariff; locks in low solar PPA rates from a third-party developer. Often combined with off-site solar plants delivering to the consumer via the grid.
What are wheeling charges?
Fees paid to the DISCOM for using its distribution network. Typical ₹0.50–1.50/kWh depending on state and voltage. Plus cross-subsidy surcharge in some states.
Is Open Access available everywhere?
Concept national but rules vary by state. Karnataka, Maharashtra, Gujarat have strong Open Access markets. Some states (Tamil Nadu) have restrictive policies.
