Comprehensive Guidelines for Optical Fiber in Power Systems

The Central Electricity Authority (CEA) of India introduced Comprehensive Guidelines for the usage and sharing of Optical Ground Wire (OPGW) and Underground Fiber Optic (UGFO) cables. These guidelines aim to enhance power system communication while balancing commercial interests. Developed collaboratively by a committee of experts, the guidelines serve as a structured framework for fibre allocation across the power transmission network.

Background and Purpose

The guidelines were established to address the growing need for efficient communication within power systems. With increasing demands on the grid, there is a need for a clear protocol for fibre allocation. The CEA aims to ensure that grid communication needs are met while allowing for commercial utilisation of spare fibre capacity.

Prioritisation of Grid Needs

The guidelines emphasise the importance of prioritising fibre allocation for critical grid communications. This ensures that essential grid operations are not compromised. Free spare fibres are mandated for future grid requirements, securing long-term operational integrity.

Sharing Framework

A well-defined sharing framework has been created. This framework facilitates collaboration among stakeholders such as Central Transmission Utility (CTU), State Transmission Utilities (STUs), and Transmission Service Providers (TSPs). It aims to streamline the process of sharing spare fibre capacity, promoting effective resource management.

Commercial Utilisation with Safeguards

While the guidelines allow for leasing spare fibres for non-grid applications, strict safeguards are in place. Leasing contracts must include a termination clause. This clause requires a maximum notice period of 18 months for reclaiming fibres for grid applications, ensuring that future grid needs are not jeopardised.

Due Diligence and Compliance

The guidelines stress the necessity of due diligence in assessing future grid communication needs. Compliance with applicable regulations from CEA, CERC, and SERC is mandatory. This ensures that all stakeholders operate within a regulated framework, maintaining the integrity of the power system.

Scalability for Future Needs

Utilities are encouraged to plan for scalability by installing OPGW with 48 or 96 fibre cores. This approach provides sufficient capacity for last-mile connectivity and future expansions. Effective use of Right of Way (ROW) is also promoted to enhance network capabilities.

Maintenance of Database

A comprehensive database will be maintained to monitor the allocation and utilisation of OPGW fibres. This database is crucial for ensuring transparency and accountability among stakeholders. It will serve as a reference point for fibre usage and allocation.

Technological Neutrality

The guidelines promote technological neutrality. Stakeholders can choose between the IEEE C37.94 protocol over shared fibre or separate optical fibres. This flexibility allows for the implementation of various differential protection schemes according to specific needs.

Future Implications

By promoting efficient fibre allocation and sharing, these guidelines aim to create a more reliable and resilient power grid. They also facilitate better resource management across the power sector, preparing it for future challenges.
