Adani Energy Solutions Limited has achieved a major milestone in urban power infrastructure development with the commissioning of a 1,000 megawatt (MW) high-voltage direct current (HVDC) transmission link between Kudus and Aarey. This strategic infrastructure project aims to strengthen power supply reliability across the Mumbai Metropolitan Region (MMR) while enabling greater integration of renewable energy sources.

Project Specifications and Infrastructure

The transmission project, executed by Adani Electricity Mumbai Infrastructure Limited (AEMIL), a subsidiary of Adani Energy Solutions Limited, represents a sophisticated engineering solution designed for dense urban environments. The infrastructure combines both overhead and underground transmission corridors to navigate Mumbai's complex urban landscape.

The project incorporates Voltage Source Converter (VSC)-based HVDC technology, which enables faster and more precise control of power flows while improving voltage stability and enhancing grid reliability in space-constrained urban environments.

Strategic Response to Grid Vulnerabilities

The HVDC link was conceived following the October 2020 Mumbai blackout, which exposed critical vulnerabilities in the city's power supply infrastructure. This project reflects a comprehensive approach to strengthening grid resilience and reliability across one of India's most energy-intensive urban clusters.

The transmission link enables Mumbai and the MMR to draw more electricity from outside the city, including renewable energy generated in other regions. While Mumbai maintains existing connections to the national grid, the HVDC link enhances connectivity by enabling more controlled, efficient, and higher-capacity power flows, particularly for renewable energy integration.

Operational Benefits and Technology Advantages

The VSC-based HVDC technology deployed in this project offers several key operational benefits that enhance the overall power infrastructure performance:

• Dynamic voltage support for improved grid stability
• Reduced transmission losses over long distances
• Black-start capability enabling power restoration without external sources
• Faster recovery in the event of outages
• Enhanced control of power flows for renewable energy integration

The Kudus–Aarey link ranks among the largest urban HVDC infeeds globally and is expected to significantly increase the share of power sourced from outside Mumbai, reducing pressure on in-city generation facilities.

Leadership Perspective

Kandarp Patel, CEO of Adani Energy Solutions Limited, emphasized the project's significance: "With the commissioning of the Aarey–Kudus transmission line, Mumbai now has a modern power corridor capable of integrating large-scale renewable energy with high reliability. It is one of the fastest HVDC project ever commissioned which is powered by advanced VSC-based HVDC technology. The project enhances grid stability, decongests existing networks and strengthens the city's energy security."

Company Profile and Market Position

The company serves approximately 13 million consumers in metropolitan Mumbai and the industrial hub of Mundra SEZ through its retail electricity distribution business, while expanding its smart metering capabilities to become India's leading smart metering integrator.

Adani Energy Solutions Limited has delivered strong operational performance in Q4FY26, showcasing robust growth across its transmission, distribution, and smart metering businesses. The company's comprehensive operational update demonstrates continued excellence in infrastructure development and service delivery.

Transmission Business Achieves Network Expansion

The transmission business recorded significant progress during Q4FY26, with the network length expanding to 27,949 ckm compared to 26,696 ckm in Q4FY25. This growth was driven by new project wins, reflecting the company's strong bidding capabilities and market positioning.

A major highlight was the commissioning of AESL's second HVDC project, the Mumbai HVDC Project, which strengthens the city's transmission capacity by 1000 MW. This development supports growing peak demand while enhancing grid reliability and advancing Mumbai's climate action goals.

Distribution Operations Show Consistent Improvement

The distribution business, comprising AEM Mumbai and MUL Mundra, demonstrated strong operational metrics and customer service improvements.

AEM Mumbai Performance

AEM Mumbai maintained exceptional service standards with supply reliability at 99.997% levels and improved system reliability parameters. The distribution loss improved to 4.20% from 4.31% in the previous year, remaining well below regulatory norms. Consumer complaints declined significantly to 66,319 from 93,973, reflecting efficient operations and network strengthening initiatives.

MUL Mundra Shows Strong Growth

MUL's operations in Mundra demonstrated robust industrial demand with units sold growing 46% year-on-year to 368 million units compared to 253 million units in Q4FY25.

Smart Metering Business Achieves Major Milestone

The smart metering division reached a significant achievement by surpassing its guidance of 1 crore cumulative smart meter installations during Q4FY26. This milestone demonstrates strong operational efficiency and sets new execution benchmarks in the industry.

Recognition and Awards

AESL received multiple recognitions during the quarter, including:

• BBB+ (Stable) long-term foreign currency rating from Japan Credit Rating Agency
• Recognition among India's Top 60 Most Sustainable Companies (IMSC 2024-25)
• Par Excellence Award at INSSAN's 1st National Creativity Summit
• Single-Use Plastic (SUP) Free certification by CII across 64 O&M sites

AEM Mumbai retained its position as India's top-ranked distribution utility for the second consecutive year with a score of 92.5 and an A+ consumer service rating. The company also received rating upgrades to IND AAA (Stable) by India Ratings and CRISIL AAA (Stable) for its proposed NCDs.

Full Year FY26 Performance Highlights

For the full fiscal year FY26, AESL maintained consistent operational excellence with transmission network availability at 99.70% and AEM Mumbai's distribution loss improving to 4.21% from 4.77% in FY25. The consumer base grew to 3.27 million, while collection efficiency remained robust at 100.54%.
