The Government of India has taken a decisive step to enhance the adoption of renewable energy. The Central Electricity Authority has announced that all future solar project tenders must integrate energy storage systems. This initiative aims to address the challenges of intermittency associated with solar power and improve grid stability.
Energy Storage Requirements
The new advisory mandates that solar projects must include at least two hours of co-located energy storage. This storage capacity should equal 10% of the installed solar capacity. Such a requirement will ensure that excess solar energy generated during the day can be stored for use during non-solar hours.
Impact on Power Purchase Agreements
State utilities will be encouraged to sign power purchase agreements more readily. The integration of energy storage will provide critical support during peak demand periods. This is expected to enhance the reliability of solar power supply and reduce dependency on fossil fuels.
Benefits for Distribution Companies
Distribution companies are now required to mandate energy storage with rooftop solar installations. This move will help manage the fluctuations in solar power generation and ensure a consistent energy supply to consumers.
Grid Stability and Optimization
The integration of energy storage systems is crucial for grid stability. It allows for better optimisation of power supply during hours when solar generation is low. This initiative is expected to enhance the overall efficiency of the energy grid.
Future Projections
The government estimates that by 2030, approximately 14 GW/28 GWh of storage-backed solar projects can be deployed. This aligns with India’s ambitious goal of achieving 500 GW of renewable energy capacity by the same year.
Decline in Battery Prices
A factor aiding this transition is the recent decline in battery prices. Lower costs for storage solutions are expected to reduce power purchase costs during non-solar hours. This economic advantage will further incentivise the adoption of energy storage technologies.
Compliance Mechanisms
The designated agencies managing the annual bidding trajectory of 50 GW, such as the Solar Energy Corporation of India (SECI), NTPC, and NHPC, have been instructed to include compliance mechanisms in tenders. This will ensure that energy storage systems are operational and available when needed.
Alignment with Renewable Energy Goals
This initiative is a vital component of India’s broader strategy to transition to renewable energy sources. It reflects a commitment to sustainable development and energy security in the face of climate change challenges.

Answer Hints:
1. Critically analyse the impact of energy storage systems on solar power generation in India.
- Energy storage systems mitigate intermittency by storing excess solar energy for use during non-solar hours.
- They enhance grid stability, allowing for a more reliable power supply during peak demand periods.
- Integration of storage can lead to increased power purchase agreements from state utilities, promoting investment in solar projects.
- Storage systems contribute to optimizing the overall efficiency of the energy grid.
- The mandate for storage in solar projects aligns with India’s goal of achieving 500 GW of renewable energy by 2030.
2. What are the challenges faced in integrating renewable energy sources into the national grid? Discuss with examples.
- Intermittency of renewable sources like solar and wind can lead to fluctuations in power supply.
- Insufficient grid infrastructure can hinder the distribution of renewable energy effectively across regions.
- Energy storage solutions are still developing, which limits the ability to store excess energy for later use.
- Regulatory and policy frameworks may not be fully supportive or aligned with renewable energy integration.
- Examples include states facing blackouts due to sudden drops in solar output during cloudy weather.
3. Estimate the significance of battery price reduction in promoting renewable energy adoption.
- Lower battery prices make energy storage solutions more affordable for consumers and businesses.
- Reduced costs lead to lower overall power purchase costs during non-solar hours, encouraging adoption.
- Affordability of storage can enhance the viability of solar projects and increase investor interest.
- Price reductions can spur innovation and competition in the energy storage market.
- As batteries become cheaper, they facilitate the transition towards a more decentralized and resilient energy system.
4. Point out the role of government policies in achieving India’s renewable energy targets by 2030.
- Government policies provide a framework for investment in renewable energy projects through incentives and subsidies.
- Mandates like energy storage requirements in solar projects drive technological improvements and capacity building.
- Clear policy goals, such as the 500 GW target, create a roadmap for stakeholders across the energy sector.
- Regulatory support for power purchase agreements enhances market stability and investor confidence.
- Government-led initiatives and collaborations with agencies ensure compliance and effective implementation of renewable strategies.
