The Central Electricity Authority (CEA) has released comprehensive guidelines for the usage and sharing of fiber cores in Optical Ground Wire (OPGW) and Underground Fiber Optic (UGFO) cables in power systems. These guidelines provide a structured framework to enhance data exchange, real-time monitoring, and grid reliability.
A key recommendation is uniform fiber allocation, ensuring dedicated cores for critical grid operations while permitting the commercial use of excess fibers. Entities must comply with CEA’s technical standards for communication and cybersecurity. In high-growth areas, new installations should use 48-96 fiber core OPGW to accommodate future communication needs.
For commercial leasing of spare fibers, utilities must include an 18-month termination clause in contracts to reclaim fibers for grid applications when needed. State Transmission Utilities (STUs) and Transmission Service Providers (TSPs) must assess grid communication needs at least five years ahead before leasing.
The guidelines also emphasize OPGW’s role in supporting advanced metering, automation, and smart grid integration. The Central Transmission Utility (CTU) and STUs will maintain a centralized database to track fiber usage, while Regional Power Committees (RPCs) will handle disputes and ensure compliance.
