Ensuring grid security, commercial balance, and future-proof power transmission infrastructure, CEA introduces new guidelines for sharing and leasing fibre in OPGW/UGFO cables.
The Central Electricity Authority (CEA), under the Ministry of Power, has recently introduced guidelines for the usage and sharing of fibre cores in Optical Ground Wire (OPGW) and Underground Fiber Optic (UGFO) cables for power system applications.
Developed by a committee led by the CEA’s Member (Power Systems) and consisting of representatives from key stakeholders, including Central Transmission Utility (CTU) and State Transmission Utilities (STUs), these guidelines establish a structured approach to fibre allocation and sharing across the power transmission network.
The primary goal is to balance commercial opportunities with the need for secure, reliable, and scalable grid operations. The guidelines ensure that fibre allocation prioritises grid communications, leaving spare capacity for future requirements. A clear framework has also been introduced to share unused fibre between stakeholders, such as transmission utilities and service providers.
The guidelines permit leasing spare fibre for non-grid applications, with provisions to safeguard grid needs. Contracts must include a termination clause allowing a maximum of 18 months’ notice to reclaim fibre for grid use if necessary.
In addition, utilities are encouraged to plan for future needs by installing OPGW with 48/96 fibre cores to support grid expansion and last-mile connectivity.
Another key aspect is the creation of a comprehensive database to monitor fibre allocation, ensuring transparency and accountability. Furthermore, the guidelines offer flexibility by allowing the use of the IEEE C37.94 protocol or separate fibres for differential protection schemes, promoting technological neutrality.
According to the Ministry, these guidelines aim to enhance the reliability, resilience, and future-readiness of the power grid while ensuring effective resource management across the sector. The document is available on the CEA website for stakeholders’ reference.
