Summary
India’s power system is undergoing a rapid transformation driven by large-scale integration of renewable energy (RE) to meet its target of achieving 500 GW of non-fossil fuel capacity by 2030. While this transition supports sustainability objectives, the growing share of variable renewable generation poses significant operational and commercial challenges related to forecasting accuracy, scheduling, grid stability, and deviation management. To address these challenges, the Aggregator framework has emerged as a key institutional mechanism for coordinated integration of renewable energy into the Indian power grid. As
Read more Read lessIndia’s renewable penetration continues to increase, aggregation is expected to play a critical role in enabling secure, efficient, and sustainable power system operation.
This paper presents an overview of the Aggregator model as implemented under the Central
Electricity Regulatory Commission (CERC) regulatory framework, including the registration process, operational responsibilities, and interaction with Regional Load
Despatch Centres (RLDCs). The methodology for aggregation of generation schedules and actual energy injection at Inter-State Transmission System (ISTS) interconnection points is described through representative metering configurations. The paper also explains the treatment of aggregated renewable generation under the Deviation Settlement Mechanism
(DSM) and the associated commercial settlement process.
Through analytical examples, the paper demonstrates the operational and financial benefits of aggregation. Portfolio-based aggregation enables partial offsetting of individual generator deviations, improves scheduling efficiency, and reduces exposure to deviation charges.
