Technical Assistance on Developing the Nigerian Electricity Regulatory Commission’s Capacity to Evaluate System Planning: Guide for Processes and Methodologies for Review, Approval and Monitoring (RAM) of Transmission, Generation and Distribution Plans

The commission's role in reviewing, approving, and monitoring transmission, generation, and distribution plans is essential to ensure a reliable and efficient power supply. The guide for processes and methodologies for review, approval, and monitoring (RAM) of transmission, generation, and distribution plans is designed to enhance the commission's capacity in this area. The guide outlines the key issues and considerations in the review process, including definite forecasted load, contingency criteria, steady state criteria, stability criteria, reliability criteria, quality of supply criteria, environmental criteria, financial criteria, protection criteria, and stakeholder engagement. The guide also provides detailed procedures and tool options for the review and approval of system plans by market participants. This includes an overview of methodologies and practices for power system planning, tool options for power system planning, key modules of the tools required for reviewing system plans, and procedures for application of key modules in review of expansion plans. The review, approval, and monitoring (RAM) templates for system planning are an essential component of the guide. These templates include review templates for load forecast, load projection, generation forecast, generation expansion plan, transmission expansion plan, distribution expansion plan, power procurement plan, generation adequacy analysis, transmission adequacy analysis, and system adequacy analysis. The templates also include sub-templates for key components in generation expansion plan review, transmission expansion plan review, and distribution expansion plan review. Monitoring practices and procedures for the generation, transmission, and distribution system plans are also outlined in the guide. This includes a framework for procurement and investments in the Nigerian power sector, which includes preparation process, procurement phase, implementation (investment) process, and operations and monitoring process. The guide also provides a list of abbreviations and definitions used in the power sector, including Abuja Electricity Distribution Company (AEDC), Approved Generation Adequacy Report (AGAR), Approved Generation Plan (AGP), Approved Load Demand Forecast (ALDF), and Available Net Energy (ANE). The Nigerian Electricity Regulatory Commission's capacity to evaluate system planning is critical to ensuring a reliable and efficient power supply in the country. The guide for processes and methodologies for review, approval, and monitoring (RAM) of transmission, generation, and distribution plans is an essential tool for enhancing the commission's capacity in this area.
