Atomic Energy Regulatory Board (AERB)

- 08 Jul 2025
In News:
India’s nuclear regulator, the Atomic Energy Regulatory Board (AERB), has granted the Licence for Operation of Units 3 and 4 of the Kakrapar Atomic Power Station (KAPS) in Gujarat — India’s first indigenously developed 700 MWe Pressurised Heavy Water Reactors (PHWRs).
Key Highlights:
- Operational Approval: The AERB concluded multi-stage design and commissioning safety reviews before granting the licence for both reactors.
- KAPS-3: Achieved full-power commissioning in August 2023.
- KAPS-4: Achieved full-power commissioning in August 2024.
- Licence Details:
- Issued on July 3, 2025.
- Valid for a period of five years.
- Granted to the Nuclear Power Corporation of India Limited (NPCIL).
Significance of the Development:
- These reactors are part of India’s first fleet of 700 MWe PHWRs, marking a major milestone in the country’s indigenous nuclear energy capabilities.
- The licensing process involved rigorous multi-tiered safety assessments spanning the full lifecycle:
- Siting
- Construction
- Commissioning
- Full-power operation
- Review was conducted with contributions from AERB and technical support organisations, involving over 15 years of evaluation.

- The 700 MWe PHWR design is an upgraded version of the 540 MWe model.
- A similar 700 MWe reactor began commercial operation at Rawatbhata (Rajasthan) in March 2025.
Broader Impact:
- The licence is a boost to NPCIL’s fleet-mode approach, which involves building 10 such 700 MWe PHWRs across India.
- It reinforces India’s commitment to self-reliance in nuclear technology under the broader Atmanirbhar Bharat initiative.
- It enhances the nation's ability to meet low-carbon energy targets through domestic nuclear capacity.
India Energy Stack (IES)

- 02 Jul 2025
In News:
In a transformative move aimed at digitising India’s power sector, the Ministry of Power has announced the conception of the India Energy Stack (IES) — a Digital Public Infrastructure (DPI) initiative designed to build a unified, secure, and interoperable digital ecosystem across the energy value chain.
This effort aligns with India’s goals of achieving a $5 trillion economy and meeting its Net Zero commitments, while addressing the growing complexities of a rapidly evolving energy landscape marked by renewables, electric vehicles, and consumer-centric markets.
What is India Energy Stack (IES)?
The India Energy Stack is envisioned as a standardised, open, and secure digital infrastructure to:
- Streamline operations in the power sector
- Empower consumers with access to real-time, consent-based data
- Integrate renewable energy into the national grid
- Enhance the efficiency of Distribution Companies (DISCOMs)
The initiative is spearheaded by the Ministry of Power, drawing inspiration from successful DPI models like Aadhaar (identity) and UPI (digital payments).
Core Features of IES
- Unique IDs: Assigned to consumers, assets, and energy transactions
- Real-time Data Sharing: Consent-based access for secure and accountable data exchange
- Open APIs: Enabling seamless integration across utility systems and third-party applications
- Consumer Empowerment Tools: Market access platforms, billing transparency, demand response options, and innovation support
- Interoperability: Standardised protocols for all stakeholders in the electricity ecosystem
Implementation Strategy
1. Proof of Concept (PoC) – 12 Months
A year-long pilot phase will test the India Energy Stack using real-world scenarios in partnership with selected utilities and DISCOMs.
2. Utility Intelligence Platform (UIP)
The UIP is a modular, analytics-driven application built on the India Energy Stack. It aims to:
- Provide real-time insights to utilities, policymakers, and regulators
- Enable smart energy management
- Enhance decision-making for grid operations and consumer services
3. Pilot Regions
The PoC will be conducted in collaboration with DISCOMs in:
- Mumbai
- Gujarat
- Delhi
Institutional Framework
- A dedicated Task Force has been established by the Ministry of Power.
- It includes experts from:
- Technology domain
- Power sector operations
- Regulatory bodies
- The Task Force will guide:
- System architecture design
- Pilot implementation
- National scale-up strategy
Expected Outcomes
- India Energy Stack White Paper for public consultation
- UIP deployment in pilot cities
- National roadmap for phased rollout of IES across all states and UTs
- Improved grid stability, energy access, and transparency in service delivery
- Enhanced integration of renewable energy sources into the mainstream grid
Significance for India’s Power Sector
The India Energy Stack has the potential to be a game-changer for the power sector, enabling:
- Modernisation of legacy systems
- Digital empowerment of consumers
- Efficient energy trading and billing
- Decentralised and democratised power governance
As India undergoes its green energy transition, IES will serve as the digital spine supporting clean, accountable, and consumer-centric power distribution.
Ghatampur Thermal Power Project
- 02 Jun 2025
In News:
Prime Minister Narendra Modi recently dedicated Unit-1 (660 MW) of the Ghatampur Thermal Power Project, located in Kanpur Nagar, Uttar Pradesh, marking a major step forward in India’s thermal power capacity and energy security goals.
Project Overview
