PM KUSUM Scheme and Battery Storage, Key Developments

March 30, 2026

PM KUSUM Scheme Latest News

The government is considering adding battery storage under the revamped PM-KUSUM 2.0 scheme.

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 and reduce dependence on diesel and grid electricity.
It seeks to ensure energy security for farmers while supporting India’s renewable energy targets.
Objectives and Features
- Promote solarisation of agricultural pumps.
- Provide a reliable and affordable power supply to farmers.
- Reduce subsidy burden on state electricity distribution companies (DISCOMs).
- Enable farmers to generate additional income by selling surplus power to the grid.
- The scheme is implemented by the Ministry of New and Renewable Energy (MNRE).
Funding Pattern
- Central Government: 30% subsidy.
- State Government: 30% subsidy.
- Farmer contribution: 40% (with provision for bank loans).
- This shared funding model ensures affordability and wider participation.

Components of PM-KUSUM

Component A
- This component focuses on setting up decentralised, grid-connected solar power plants (up to 2 MW capacity).
- Farmers, cooperatives, and panchayats can install these plants on barren or cultivable land and sell electricity to DISCOMs.
Component B
- Under this component, standalone solar-powered agricultural pumps are installed in off-grid areas.
- It helps farmers reduce dependence on diesel pumps and ensures uninterrupted irrigation.
Component C
- This component involves solarisation of existing grid-connected agricultural pumps.
  - It has two sub-models: Individual Pump Solarisation (IPS) and Feeder-Level Solarisation (FLS).
- IPS allows farmers to solarise their own pumps, while FLS solarises entire agricultural feeders, improving efficiency at scale.

Achievements and Progress

Target: 34.8 GW solar capacity addition.
Installed capacity: About 12,164 MW as of February 2026.
Over 10 lakh standalone solar pumps installed under Component B.
More than 13 lakh pumps are covered under feeder-level solarisation.
Increased adoption of clean energy in rural areas.
Despite progress, implementation has been slower than expected due to financial and operational challenges.

Challenges in Implementation

Delays in financial closure and loan disbursement.
High upfront cost for farmers.
Coordination issues between central and state agencies.
Grid integration challenges due to variability in solar power generation.

News Summary

The government is planning a revamped version of the PM-KUSUM scheme, likely to be called PM-KUSUM 2.0, to address existing gaps and improve efficiency.
Introduction of Battery Storage
- The Centre is considering adding battery energy storage to the scheme.
- The current scheme focuses only on solarisation and does not include storage systems.
- Battery storage is being proposed to improve energy management.
Need for Battery Storage
- There is a mismatch between solar energy generation and agricultural power demand.
- Solar generation peaks during midday.
- Agricultural demand starts in the morning and continues beyond sunset.
- This mismatch creates operational challenges for power distribution and grid stability.
- Battery storage can address this issue by storing excess solar energy during peak production and supplying it later when demand persists.
Policy Discussions
- Different ministries have varying views on the extent of storage capacity.
- Ministry of Power proposes up to 4 hours of storage.
- MNRE suggests a 2-hour storage capacity.
- Discussions are ongoing, including consultations with the Ministry of Finance.
Extension of Timeline
- The Centre has extended timelines for financial closure and project completion under the existing scheme.
- This decision was taken due to delays reported by stakeholders, particularly in securing loans from financial institutions.
Transition to PM-KUSUM 2.0
- The current scheme is set to be subsumed into the new PM-KUSUM 2.0 framework.
- States have been advised to coordinate with banks to expedite pending projects before the transition.

LPG vs LNG Explained, Why West Asia War Hit LPG Supply Harder in India

March 30, 2026

LPG vs LNG Latest News

The disruption of shipping through the Strait of Hormuz due to the West Asia conflict has significantly impacted India’s energy supplies, especially LPG and LNG.
India imports about 60% of its LPG needs, and since 90% of these imports pass through the Strait, around 54% of LPG supply is affected. This has forced the government to cut supplies to commercial and industrial users to prioritise households.
Natural gas has also been impacted, though to a lesser extent. India imports about half of its gas as LNG, with 55–60% coming via the Strait, leading to a disruption of roughly 30% of supply.
To manage this, supplies to industries have been reduced while ensuring availability for households (PNG) and transport (CNG). Overall, the LPG situation is more severe, prompting the government to encourage a shift to PNG where possible.

Chemistry and Composition of LPG and LNG

Liquefied Petroleum Gas (LPG) is mainly a mixture of propane and butane, produced as a byproduct of crude oil refining and natural gas processing. It may also contain small amounts of other hydrocarbons.
In contrast, Liquefied Natural Gas (LNG) is primarily methane, derived from natural gas.

Liquefaction Process and Storage

LPG becomes liquid under moderate pressure or low temperatures, making it relatively easy to store and transport.
LNG, however, requires extreme cooling below -160°C and must be stored in specialised cryogenic tanks, making its handling more complex and energy-intensive.

Volume and Transportation Advantage

Both fuels are liquefied to reduce volume for transport.
LPG reduces to about 1/260th of its gaseous volume, while LNG shrinks further to about 1/600th, enabling efficient long-distance transportation, especially where pipelines are not feasible.

Usage and Applications

LPG is widely used for cooking, heating, and some industrial applications, and also as a vehicle fuel in certain regions.
LNG itself has limited direct use but is mainly transported and then converted back into natural gas, which is used for cooking, transport (CNG), and industries such as fertilisers, power generation, refineries, and petrochemicals.

Delivery and Distribution Systems

LNG is transported via specialised cryogenic ships to regasification terminals, where it is converted back into natural gas and supplied through pipelines as PNG (piped natural gas) or CNG for vehicles.
In contrast, LPG is bottled in cylinders and delivered mainly by road, making it accessible even in remote areas without pipeline infrastructure.

Storage and Accessibility

LPG is easier to store, requiring only pressurised cylinders, which makes it highly portable and suitable for rural and remote regions.
PNG, however, depends entirely on pipeline connectivity and cannot be easily stored unless converted into LNG again.
As a result, LPG is preferred in areas without pipelines, while PNG is promoted in urban regions.

Convenience for Consumers

PNG offers greater convenience once infrastructure is in place, providing continuous, metered supply without the need for refills or bookings.
LPG, on the other hand, requires periodic cylinder replacement and manual handling.

Safety Considerations

PNG is considered safer because natural gas is lighter than air, allowing it to disperse quickly in case of leaks.
LPG is heavier than air, tends to accumulate, and poses a higher risk of fire or explosion during leakage.
While LPG offers portability and wider reach, PNG provides greater convenience, safety, and efficiency in areas with established pipeline infrastructure.

Crisis Impact and Supply Prioritisation

Amid disruptions caused by the Strait of Hormuz crisis, the government has acknowledged significant stress on LPG supplies, though household consumption remains protected.
While 100% supply is ensured for PNG households and CNG transport, supplies to industrial and commercial users have been curtailed to about 80%.
The disruption is more severe for LPG (about 54% affected) compared to natural gas (around 30% affected).
India has a much larger LPG user base (33.3 crore households) compared to only 1.5 crore PNG connections.

Push for PNG Expansion

To ease pressure on LPG, the government is encouraging consumers to switch to PNG where available.
City Gas Distribution (CGD) companies are offering incentives like free gas and waived connection charges.
The Centre has also urged states to fast-track PNG network expansion and offered additional LPG allocations as incentives.

Boosting Domestic LPG Production

The government has directed refiners to maximise LPG production by diverting inputs like propane and butane from petrochemicals.
This has increased domestic LPG output by 40%, raising its share in meeting demand from 40% to about 55%.

Demand Management Measures

To manage limited supplies, the government has increased the gap between LPG cylinder bookings to 25 days in urban areas and 45 days in rural areas.
It has also activated alternative fuels like kerosene, fuel oil, biomass, and coal for industrial and commercial users to offset LPG shortages.

LPG vs LNG FAQs

Q1: What is the difference between LPG vs LNG?

Ans: LPG vs LNG differs in composition and use. LPG vs LNG shows LPG is propane-butane mix for cooking, while LNG is methane used for transport and industrial energy.

Q2: Why was LPG supply hit harder than LNG?

Ans: LPG vs LNG analysis shows 90% LPG imports pass through Hormuz, disrupting 54% supply, while LNG disruption was about 30%, making LPG crisis more severe.

Q3: How are LPG vs LNG transported?

Ans: LPG vs LNG differ in transport—LPG is supplied in cylinders via road, while LNG is transported in cryogenic ships and pipelines after regasification.

Q4: Why is PNG preferred over LPG in cities?

Ans: LPG vs LNG comparison shows PNG offers continuous, safer supply via pipelines, while LPG requires cylinder replacement, making PNG more convenient in urban areas.

Q5: How is India managing LPG vs LNG crisis?

Ans: LPG vs LNG crisis management includes boosting LPG production by 40%, prioritising households, reducing industrial supply, and promoting PNG expansion to reduce LPG demand.

IAS Resignation Rules Explained, Process, Delay, Withdrawal & Legal Issues

March 30, 2026

IAS Resignation Rules Latest News

Kannan Gopinathan, a former IAS officer who resigned in 2019 citing restrictions on freedom of expression in Kashmir, has alleged that the government has delayed accepting his resignation for over six years. This delay has prevented him from contesting elections.
His resignation is still pending with the Ministry of Home Affairs, as the final recommendation has not yet been sent to the DoPT.
Officials note that such prolonged delays are unprecedented, raising questions about the rules governing IAS resignations, timelines, and grounds for rejection.

Rules on IAS Officers and Political Activity

Under the All India Services (Conduct) Rules, serving IAS officers are strictly prohibited from associating with political parties or participating in political activities.
They are required to maintain political neutrality and uphold constitutional values at all times.

2014 Amendment and Political Neutrality

The Conduct Rules were amended in November 2014, adding new clauses to reinforce the conduct expected of senior civil servants.
Most notably, Rule 3(1) mandates that every government employee must, at all times, maintain political neutrality and remain committed to upholding the supremacy of the Constitution and democratic values.
This rule essentially codifies the foundational expectation that civil servants — regardless of which government is in power — serve the Constitution and the public, not any political party or ideology.

Gopinathan’s Case and Legal Grey Area

Kannan Gopinathan resigned from the IAS in 2019 and later joined a political party in 2024.
However, since his resignation has not yet been formally accepted, his status remains that of a serving officer, placing him in violation of conduct rules if he engages in politics.
Gopinathan has accused the government of deliberately delaying his resignation, calling it “harassment” and arguing that it is preventing him from participating in the democratic process.

Resignation Process for IAS Officers

The resignation of officers from the All India Services—IAS, IPS, and Indian Forest Service—is governed by Rules 5(1) and 5(1)(A) of the All India Services (Death-cum-Retirement Benefits) Rules, 1958.

Procedure Based on Posting

An officer serving in a state cadre must submit their resignation to the Chief Secretary of the state.
If the officer is on central deputation, the resignation is submitted to the concerned ministry or department secretary, which then forwards it to the respective state cadre with its recommendations.
In the case of AGMUT cadre officers, the process is routed through the Ministry of Home Affairs.

Key Conditions and Implications

As per Rule 5, officers who resign are not entitled to retirement benefits.
Additionally, Department of Personnel and Training (DoPT) guidelines require that the resignation must be clear and unconditional for it to be considered valid.

What Happens After an IAS Officer Submits Resignation

After resignation is submitted, the state verifies if the officer has any pending dues, vigilance cases, or inquiries—resignations are usually rejected if such issues exist.
The state then forwards its recommendation and details to the Union government.
The final decision is taken by the competent authority:
- for IAS officers, the DoPT Minister (Prime Minister);
- for IPS, the Home Minister; and
- for Indian Forest Service officers, the Environment Minister.

Can the Government Delay IAS Resignations

There is no fixed time limit for accepting an IAS officer’s resignation.
However, a DoPT circular states that it is generally not in the government’s interest to retain an unwilling officer, so resignations should normally be accepted.

Conditions Where Resignation May Be Delayed or Rejected

Resignations can be withheld in certain situations.
If an officer is under suspension or facing disciplinary proceedings, the government must assess whether accepting the resignation serves public interest.
In such cases, the Central Vigilance Commission (CVC) may also be consulted.

Other Grounds for Rejection

The government also examines whether the officer has:
- Pending dues or obligations, or
- Executed service bonds (for training, scholarships, or fellowships).
For example, Arvind Kejriwal faced penalties after resigning from the IRS due to a bond violation linked to a government-funded fellowship.
If the officer holds an important position, the government may delay acceptance until suitable replacement arrangements are made, ensuring administrative continuity.

IAS Resignations Since 2010: Key Trends

RTI data from the DoPT shows that 31 IAS officers have resigned since 2010, the year the CSAT was introduced in the UPSC exam.
Of these, 11 resigned between 2010–2014 (UPA period) and 20 between 2015 and May 2025 (NDA period).
Since the introduction of CSAT, many IAS entrants have been technocrats, and a growing number have chosen to resign for better opportunities in the private sector or to enter politics, reflecting evolving career preferences among civil servants.

Can IAS Officers Withdraw Their Resignation

Yes, IAS officers can withdraw their resignation, but only under specific conditions laid down in the All India Services (Death-cum-Retirement Benefits) Rules.
Under Rule 5(1A)(i), the Union government may allow withdrawal of resignation in public interest.
However, as per a 2011 amendment, the gap between resignation and rejoining service cannot exceed 90 days.
Also, withdrawal is not permitted if the officer resigned to pursue political activities.
If an officer withdraws their resignation before it is formally accepted, it is automatically treated as withdrawn. This rule applies in cases where resignation processing is delayed.
- Shah Faesal, who resigned in 2019, was able to return to service in 2022 because his resignation had not been accepted, allowing automatic withdrawal.
The timing of acceptance is crucial—before acceptance, withdrawal is easy; after acceptance, it is restricted and conditional, especially if linked to political activity.
