In a move aimed at supporting faster integration of renewable energy, the Central Transmission Utility of India has introduced a detailed framework for granting Connectivity and General Network Access (GNA) to the inter-state power grid.
The new procedure comes as India accelerates renewable energy capacity addition and seeks more efficient access to its transmission network. It outlines a structured, step-by-step process for entities seeking connectivity to the Inter-State Transmission System (ISTS) under the CERC Connectivity and GNA Regulations 2022, Energetica India reported.
Under the revised framework, power generators, renewable energy developers and bulk consumers must submit applications through an online portal, providing detailed technical and financial information. Incomplete or inaccurate applications may be rejected or returned for correction.
The procedure introduces a comprehensive technical evaluation process, with applications assessed for generation capacity, grid compatibility, evacuation arrangements, electrical systems and metering infrastructure. The utility may seek clarifications or require modifications before granting approval.
It also mandates the signing of a Connectivity Agreement before any physical link to the grid is established, ensuring regulatory compliance.
To strengthen oversight, the framework requires approved projects to submit regular progress reports on transmission infrastructure development. It also provides for strict action, including cancellation of access rights, in cases of delays or non-compliance.
The guidelines define technical standards and capacity thresholds for different voltage levels to maintain grid stability. They also include provisions for relinquishment of access and a transition from the earlier Long-Term Access (LTA) system to the GNA regime.
Officials said the new rules are expected to improve transparency, reduce delays and facilitate the smooth integration of renewable energy into the national grid while ensuring efficient use of transmission infrastructure.
