PM-KUSUM 2.0 Revamp: Solar Pumps, Battery Storage & Rural Energy Explained

Why in News ?

The government is planning a revamped version of the PM-KUSUM scheme, likely termed PM-KUSUM 2.0, to address implementation gaps, improve efficiency, and integrate battery storage systems for better energy management in agriculture.

Background and Context

About PM-KUSUM Scheme

The Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM), launched in 2019, aims to :

• Promote solar energy use in agriculture
• Reduce dependence on diesel pumps
• Increase farmers’ income through energy generation

Key Components

Component A (Decentralized Ground/Stilt Mounted Solar Power Plants) :

Goal: Setup 10,000 MW of renewable energy-based power plants (REPP) or barren or cultivated land,.

• Capacity: Individual farmers, cooperatives, or groups can install plants up to 2 MW capacity.
• Benefit: Allows farmers to sell power to DISCOMs, ensuring a steady income for 25 years.

Component B (Standalone Solar Agriculture Pumps) :

• Goal: Installation of 14-20 lakh standalone solar-powered agriculture pumps to replace diesel pumps.
• Capacity: Individual pumps up to 7.5 HP
• Benefit: Central Financial Assistance (CFA) of 30% (50% in NER, Hilly, and Island regions) is provided

Component C (Solarization of Grid-Connected Agriculture Pumps):

• Goal: Solarize 15-35 lakh existing grid-connected agricultural pumps.

Capacity: Individual pumps up to 7.5 HP

• Benefit: Farmers can use solar power for irrigation and sell surplus power to DISCOMs. This includes feeder-level solarization.

Progress So Far

• Over 10 lakh standalone solar pumps installed
• More than 13 lakh pumps solarised at feeder level
• Increased adoption of clean energy in rural areas

However, progress has been slower than expected due to financial, institutional, and technical challenges.

Need for Revamp: Why PM-KUSUM 2.0 ?

The scheme requires restructuring due to :

• Implementation delays across states
• Financial constraints faced by farmers
• Operational inefficiencies in power distribution
• Mismatch between solar generation and agricultural demand

Key Features of PM-KUSUM 2.0

1. Introduction of Battery Storage

The revamped scheme proposes integrating battery energy storage systems.

Purpose :

• Store excess solar energy during peak generation
• Supply power during non-solar hours

2. Improved Energy Management

Battery storage will help :

• Balance supply-demand mismatch
• Improve grid stability
• Ensure reliable power for irrigation

3. Policy-Level Discussions

• Ministry of Power proposes 4-hour storage capacity
• Ministry of New and Renewable Energy (MNRE) suggests 2-hour capacity
• Final decision under inter-ministerial consultation

4. Extended Timelines

• Government has extended deadlines for :
  • Financial closure
  • Project completion
    •  Aimed at addressing delays in loan disbursement

5. Transition Framework

• Existing scheme to be subsumed under PM-KUSUM 2.0
• States directed to fast-track pending projects

Challenges in Implementation

1. Financial Constraints

High upfront costs for solar pumps continue to discourage small and marginal farmers despite subsidies.

2. Delays in Credit Access

Slow loan approvals and financial closure have significantly delayed project execution across states.

3. Institutional Coordination Issues

Lack of effective coordination between central ministries, state governments, DISCOMs, and financial institutions has hindered implementation.

4. Grid Integration Challenges

Solar energy variability creates instability in power supply, especially in regions with weak grid infrastructure.

5. Demand-Supply Mismatch

Solar generation peaks during midday, whereas agricultural demand extends beyond daylight hours, creating operational inefficiencies.

6. Limited Technical Capacity

Inadequate local capacity for installation, maintenance, and monitoring affects long-term sustainability.

Significance of PM-KUSUM 2.0

1. Boost to Renewable Energy

• Accelerates India’s transition to clean energy
• Reduces reliance on fossil fuels

2. Enhancing Farmer Income

• Farmers can generate and sell surplus power
• Reduces irrigation costs

3. Strengthening Energy Security

• Decentralised solar generation reduces grid pressure
• Improves rural power reliability

4. Climate Change Mitigation

• Reduces carbon emissions from diesel pumps
• Supports India’s climate commitments

5. Rural Development

• Promotes sustainable agriculture
• Enhances rural infrastructure and livelihoods

Way Forward

1. Integrating Battery Storage Effectively

A balanced approach must be adopted in determining optimal storage capacity to ensure cost-efficiency and grid stability.

2. Improving Access to Finance

Government should expand credit support, interest subvention, and innovative financing models to make solar pumps affordable.

3. Strengthening Institutional Coordination

Better coordination between ministries, DISCOMs, and financial institutions is essential for smooth implementation.

4. Enhancing Grid Infrastructure

Investment in smart grids and transmission networks is necessary to handle renewable energy variability.

5. Capacity Building and Awareness

Training farmers and local technicians can improve adoption, maintenance, and long-term sustainability.

6. Encouraging Private Sector Participation

Involving private players can bring efficiency, innovation, and faster execution.
