The Central Transmission Utility of India Limited (CTUIL) has introduced a detailed procedure for granting Connectivity and General Network Access (GNA) to the inter-State transmission system, in line with the Central Electricity Regulatory Commission (CERC) Regulations 2022. This move is aimed at making it easier and more transparent for power projects, especially renewable energy projects, to connect to the national grid.
Under the new framework, the entire application process has been made digital through the National Single Window System (NSWS) portal. Developers of generating stations, energy storage systems, and bulk consumers can apply online by selecting the required format based on their project needs. This includes fresh connectivity, adding capacity to an existing connection, or transferring connectivity rights. Applicants are required to pay a non-refundable fee at the time of submission.
Eligibility for connectivity is mainly based on the size of the project. In most cases, the minimum requirement is 50 MW, while projects in the North Eastern region can apply with a minimum of 25 MW. The procedure clearly states that a developer cannot hold connectivity for the same capacity in both intra-state and inter-state systems at the same time. To shift from a state network to the inter-state grid, the applicant must submit a No-Objection Certificate confirming disconnection from the state system.
Once submitted, applications go through a detailed scrutiny process. If there are major deficiencies, such as not meeting basic eligibility criteria, the application is rejected and 20 percent of the fee is forfeited. Minor deficiencies, however, can be corrected within seven working days, giving applicants a chance to complete their documentation.
An important part of the process is the Consultation Meetings for Evolving Transmission Schemes (CMETS). These meetings involve CTUIL, regional power committees, and project developers. The purpose is to discuss and plan the required transmission system for new projects. Based on these discussions, CTUIL may issue an in-principle connectivity approval. This approval may also include requirements such as building dedicated transmission lines or upgrading existing infrastructure.
To ensure that only serious projects move forward, the procedure includes financial commitments in the form of bank guarantees. Different types of guarantees are required at different stages, including those linked to project execution and payment of transmission charges. If a developer fails to pay transmission charges for more than three months, the guarantees can be encashed and the connectivity may be cancelled.
Developers must also meet certain conditions after receiving approval. These include securing at least 50 percent of the required land and achieving financial closure within a defined timeline. Project progress is monitored regularly through monthly updates and meetings with the Joint Coordination Committee, ensuring that both generation and transmission development stay aligned.
The framework also allows for transfer of connectivity and changes in ownership, provided the new entity takes full responsibility for all obligations. It also includes provisions like the Right of First Refusal for renewable energy projects seeking additional capacity. Finally, developers must sign formal connectivity agreements, which define all technical and commercial terms before the project is physically connected to the grid. This structured process is expected to support India’s growing energy needs with better planning and faster integration.
