Rajasthan's Renewable Energy Hub Faces Major Curtailment Crisis
In Rajasthan, a leading renewable energy hub in India, solar and wind power plants have been receiving directives from the State Load Despatch Centre (SLDC) in Jaipur to reduce their generation for the past 20 days. This move comes as low power demand prevents coal-fired thermal plants from shutting down completely, creating a surplus that the state cannot manage effectively.
Infrastructure and Policy Failures Exacerbate Power Waste
The state government has failed to establish battery storage systems to store surplus power during low-demand periods. A senior SLDC official explained that coal thermal plants must run continuously to ensure power availability at night, as Rajasthan lacks gas and hydro power plants that can be easily shut down and restarted. This has led to significant curtailments of renewable energy, which typically enjoys must-run status, meaning these plants are not supposed to be shut down under normal circumstances.
Impact on Investors and Developers
The Rajasthan Solar Association has raised concerns by writing to the energy department, highlighting that solar plants have faced frequent and substantial curtailments ranging from 30% to 80%, particularly during peak generation hours from 10:30 AM to 2:30 PM. This situation poses severe challenges for small-scale solar power developers, who rely on consistent generation to repay bank loans and avoid financial losses. An SLDC official noted that approximately 1,500 MW of renewable power is wasted daily due to these curtailments.
Transmission and Market Challenges Compound the Issue
Efforts to sell surplus power in the open market have been hampered by low demand, attributed to current weather conditions. Additionally, infrastructure limitations, such as insufficient transmission capacity, result in the waste of about 4,000 MW of power intended for export outside the state. The state government's attempts to expedite battery storage projects have stalled, leaving the renewable sector vulnerable.
Key Points of the Crisis:
- Solar and wind power generation reduced on SLDC orders due to low demand.
- No battery storage systems in place to absorb surplus daytime power.
- Daily waste of 1,500 MW renewable energy from curtailments.
- Loss of 4,000 MW due to inadequate transmission capacity for out-of-state power.
- Developers warn of projects becoming loss-making ventures without compensation for curtailed generation.
- Industry calls for urgent acceleration of battery storage projects to mitigate future losses.
The ongoing crisis underscores the urgent need for improved infrastructure and policy measures to support Rajasthan's renewable energy ambitions and protect investor interests.
