Quick Answer

The Central Electricity Regulatory Commission issued its Fourth Amendment to the Connectivity and General Network Access Regulations on 11 November 2026. Contemporary reporting describes conditional withdrawal of connectivity after specified delays, revised release timelines for certain connectivity bank guarantees, and non-solar-hour access for qualifying renewable-energy and energy-storage projects. These are conditional regulatory mechanisms, not unrestricted rights to connectivity or immediate refunds. The exact effective date and operative wording must be verified from the final notified text and Official Gazette before calculating legal deadlines.

What Is the CERC Fourth GNA Amendment 2026?

The amendment modifies the Central Electricity Regulatory Commission (Connectivity and General Network Access to the inter-State Transmission System) Regulations, 2022. These regulations govern connectivity and network access for eligible entities. Delayed connectivity can prevent projects from operating even after significant development expenditure. The Fourth Amendment is listed under CERC notification No. L-1/261/2021/CERC dated 11 November 2026. The official notification listing confirms issuance, while the detailed descriptions below are based on contemporary regulatory reporting where the final PDF has not been independently checked.

Can Developers Withdraw Connectivity After a Two-Year Delay?

According to published regulatory analysis, the amendment creates conditional routes for surrendering the entire connectivity quantum where final connectivity is delayed by two years or more after in-principle grant or where specified connectivity-start delays arise. A reported 45-day application window applies to qualifying events. The correct trigger must be checked case by case; it is unsafe to calculate all deadlines from the original application date. The new route is reported to concern full rather than partial withdrawal. Where withdrawal is accepted, applicable connectivity bank guarantees may be returned while the application fee is forfeited. Reports also describe a one-time 30-day transitional window for some previously expired cases. All deadlines require verification against the operative amendment and its commencement date.

How Have Conn-BG2 and Conn-BG3 Release Rules Changed?

The reported amendment shortens the release timeline for specified generation-related connectivity bank guarantees, replacing a five-year annual-instalment mechanism with release within one week after completion of one year from the project’s commercial operation date, subject to the conditions in the regulations. Reports describe transitional relief for certain already-operational projects, potentially within one month of commencement and subject to outstanding transmission liabilities. No developer should assume every guarantee or fee is refundable without checking the guarantee category, commissioning evidence, liabilities and final text.

Why Earlier Bank-Guarantee Release Matters

A bank guarantee may tie up credit limits, cash margin or collateral. Illustratively, ₹20 crore in eligible guarantees backed by a 20% cash margin could free about ₹4 crore of restricted margin when released. This is only an example, not a project-specific financial estimate. Actual benefits depend on margin, fees, collateral, conditions and timing.

Can BESS Projects Obtain Non-Solar-Hour Connectivity?

The reported framework allows qualifying renewable-energy generating stations and energy-storage systems of at least 50 MW to seek non-solar-hour connectivity at substations with available transmission margins. For eligible storage systems, published summaries describe a minimum energy capacity equal to twice the installed power capacity: a 100 MW system would therefore need at least 200 MWh under that reported threshold. Other technical and regulatory requirements may apply. The framework may also accommodate qualifying aggregation through a lead entity, subject to the final text.

Is Non-Solar-Hour Connectivity Guaranteed?

No. The mechanism is linked to available transmission margins and does not itself require the construction of new network capacity for every applicant. CTUIL’s published margin information and the project’s technical configuration should be reviewed. Non-solar hours should not automatically be equated with a fixed evening peak period; the applicable definition, scheduling and access rules control.

Does Non-Solar-Hour Connectivity Mean Free Open Access?

No. Connectivity, General Network Access, transmission-charge liability and any applicable waiver are distinct questions. A project may obtain connectivity while still being liable for charges. Waiver eligibility can depend on project configuration, commissioning, charging source and the applicable rules. Commercial modelling must address each separately.

Can Developers Change Energy Source or Project Configuration?

Regulatory reporting describes greater flexibility for certain changes of energy source, land parcels and connectivity routes. Published figures include a reported second energy-source change fee of ₹20,000 per MW of gross capacity change or ₹10 lakh, whichever is higher, and a reported combined fee for specified second land-parcel changes of ₹25,000 per MW or ₹10 lakh, whichever is higher. Some application deadlines are also reported to change. These figures and conditions should be checked directly against the final notification before submitting applications or payments.

What About Dual ISTS and Intra-State Connectivity?

The amendment reportedly recognises certain GNA transfers following asset acquisitions and permits qualifying large consumers to obtain dual inter-State and intra-State connectivity, subject to a minimum 50 MW quantum and other conditions. This is not a universal entitlement for every consumer. Technical feasibility, network arrangements and charges remain relevant.

Practical Legal Checklist for Renewable-Energy Developers

1. Verify final notification and Official Gazette commencement.
2. Record in-principle grant, final grant, firm start date and revisions.
3. Identify the qualifying withdrawal event and calculate the correct deadline.
4. Review Conn-BG2, Conn-BG3, collateral and outstanding liabilities.
5. Confirm COD documents and commissioning eligibility.
6. Check CTUIL’s available transmission margins.
7. Verify storage MW, usable MWh and technical conditions.
8. Review PPA, BESPA, financing, EPC and transmission agreements.
9. Quantify fees, margin release and lost commercial opportunity.
10. Preserve all applications, acknowledgments and correspondence.

Strongest Counterargument Against Easier Withdrawal

Transmission capacity is scarce. Unrestricted reservations and withdrawals could encourage speculative applications and obstruct serious projects. Conversely, developers should not be indefinitely penalised for qualifying delays outside their control. Conditional withdrawal, defined deadlines and proportionate financial consequences attempt to balance these interests. Implementation transparency will matter.

Commercial Risks That Remain

The amendment does not eliminate land, financing, equipment, PPA, grid congestion or commissioning risk. BESS economics still depend on charging costs, efficiency, degradation, dispatch obligations and revenue certainty. Improved connectivity rules cannot guarantee profitability or completion.

Conclusion

The Fourth GNA Amendment is an important development for solar, wind and storage developers. Its potential value lies in conditional exit options, earlier release of eligible guarantees and better utilisation of transmission capacity outside solar hours. But eligibility, deadlines, commencement and commercial effects require project-specific review of the final operative text.
