The Assam Electricity Regulatory Commission (AERC) has introduced the Draft Regulations for Grant of Connectivity to the Intra-State Transmission System (InSTS), 2025. These regulations aim to facilitate the integration of entities into the state transmission system effectively, reliably, and economically. They emphasize healthy competition in electricity generation and supply while ensuring system security. The rules will take effect from April 1, 2025, covering all applications for connectivity submitted to the State Transmission Utility (STU) from this date onward.
The regulations outline eligibility criteria for entities seeking connectivity to InSTS. Entities such as power-generating stations, renewable energy generators, and distribution licensees are eligible to apply. Additionally, trading licensees and energy storage systems (ESS) are also covered. Applications must comply with specific requirements, including submission of technical and financial details. Applicants are also required to provide bank guarantees, termed Conn-BG1, Conn-BG2, and Conn-BG3, which vary based on the voltage level and augmentation needs.
Connectivity is granted after a thorough interconnection study conducted by the Nodal Agency. This study assesses the existing system’s adequacy and identifies any augmentation required for transferring power. If no augmentation is needed, connectivity is granted within 45 days; otherwise, it takes up to 90 days. Applicants must adhere to technical standards and enter into agreements for the construction, operation, and maintenance of dedicated transmission lines and terminal bays.
The regulations permit the transfer of connectivity rights under specific conditions, such as within subsidiaries or between parent companies. Renewable energy generators can split their connectivity among different capacities post-commercial operation. Entities relinquishing their connectivity must provide advance notice and may incur charges proportional to their relinquished quantum.
In case of project delays or cancellations, connectivity can be revoked. Bank guarantees submitted by applicants may be encashed to cover costs or settle outstanding transmission charges. The Nodal Agency monitors the implementation of works under its purview, ensuring timely updates and corrective actions.
For effective metering and data transmission, applicants must develop infrastructure for real-time communication with the State Load Dispatch Centre (SLDC). The regulations also allow the injection of infirm power and the drawal of start-up power under prescribed conditions. Detailed procedures and formats for applications, agreements, and updates are to be finalized within three months of notification of these regulations.
These comprehensive measures aim to streamline connectivity processes, enhance transparency, and support the growing demand for reliable power in Assam. The framework also ensures the optimal utilization of transmission systems while accommodating future growth and advancements in energy technologies.
