RERC has notified a comprehensive framework for resource adequacy, incorporating stakeholder feedback to enhance power system reliability, particularly in a renewable energy-intensive environment.
Comprehensive Planning Framework Introduced
The regulations, finalised after a public consultation process, establish a structured approach to demand forecasting, generation planning, procurement, and compliance. The Commission stated that inputs from 14 stakeholders were considered while finalising the framework.
The objective is to ensure reliable electricity supply while facilitating the integration of renewable energy sources into Rajasthan’s power system.
Expanded Scope and Revised Capacity Credit Norms
One of the most important changes to the rules is that they now apply to power procurement entities that work for distribution companies. This is meant to make procurement practices more open and accountable.
The Commission has also revised the definition of “capacity credit” to better reflect renewable energy variability. It will now be determined based on technology, location, seasonal factors, actual generation performance, and outages, ensuring a more realistic assessment of available capacity.
Minimum Reserve Margin to Ensure Reliability
To strengthen grid stability, RERC has introduced a minimum planning reserve margin of 10%. This provision addresses challenges such as extreme weather conditions, intermittency of renewable energy, coal supply constraints, and transmission congestion.
Enhanced Demand Forecasting Requirements
In demand forecasting, utilities have been directed to use at least five years of historical data, replacing the earlier three-year requirement. Additionally, utilities must evaluate seasonal demand patterns, including summer, monsoon, winter, and evening peak demand, which are critical in renewable-heavy systems.
The framework also allows greater flexibility by permitting assessment of renewable energy contribution across a broader range of peak hours, rather than limiting it to the top 250 hours annually.
Clarity on Energy Storage and Compliance
The regulations provide clarity on energy storage by specifying that capacity credit for storage systems must consider duration, efficiency, and operational limitations. Hybrid renewable-plus-storage projects can be treated as a single resource for planning purposes.
On compliance, the Commission clarified that distribution companies will not face penalties for factors beyond their control, such as project delays or transmission constraints.
Evolving Framework for Future Needs
RERC said that the resource adequacy framework is still being worked on and will get better over time as more data, operational experience, and policy changes are made. This will make sure that it can adapt to Rajasthan’s growing renewable energy landscape.
