Ensuring Grid Reliability in India

This guide explains the concept of resource adequacy (RA) and the implementation of the Resource Adequacy Planning Framework released by India's Ministry of Power in June 2023 to ensure grid reliability amidst growing electricity demand and renewable energy integration.

• India experienced a record peak electricity demand of 240 GW in September 2023. While solar capacity grew by 275 percent over five years, reducing daytime outage risks, the country faces increased risks of power shortfalls at night. To prevent summer shortfalls, the Ministry of Power used emergency rules over the last two summers to maintain coal plant operations at full capacity using imported coal.
• The Ministry of Power released the Resource Adequacy Planning Framework (RA Framework) in June 2023. The Central Electricity Authority (CEA) uses two specific metrics to determine if a system is resource adequate: Loss of Load Probability (LOLP), which measures the annual likelihood of an outage, and Normalized Energy Not Served (NENS), which measures the expected total energy shortfall relative to annual load. The CEA targets 0.2 percent for LOLP and 0.05 percent for NENS in the National Electricity Plan.
• Implementation of the RA Framework involves a tiered planning structure. The CEA is responsible for the Long-term National Resource Adequacy Plan (LT-NRAP), a 10-year look ahead developed annually. The National Load Dispatch Center (NLDC) issues an annual Short-term National Resource Adequacy Plan (ST-NRAP) focusing on hourly demand and resource availability for the coming year. State load dispatch centers (SLDCs) allocate peak shares to Distribution Companies (Discoms), which must then demonstrate compliance with their Resource Adequacy Requirement (RAR) to state energy regulatory commissions (SERCs) and develop 10-year Distribution Licensee Resource Adequacy Plans (LT-DRAPs).
• The RA Framework encourages Discoms to adopt Integrated Resource Planning (IRP) best practices similar to those used in the US and EU. This includes using advanced planning tools, building internal expertise, and developing robust data pipelines to analyze demand variation, hydro conditions, and renewable availability. Such planning helps Discoms manage tradeoffs between in-state generation and imports, and prevents investments in generators that could become stranded assets.
