Adani Energy commissions 1,000 MW HVDC link boosting Mumbai clean energy supply, improving grid stability, reducing outages, and enabling renewable power integration. Kudus–Aarey project strengthens energy security and supports sustainable urban infrastructure growth.
In a major boost to urban energy infrastructure, Adani Energy Solutions Ltd (AESL) has successfully commissioned a 1,000 megawatt high-voltage direct current (HVDC) transmission link connecting Kudus and Aarey, marking a transformative step in strengthening electricity supply across Mumbai and the wider Mumbai Metropolitan Region (MMR).
The project, executed by its subsidiary Adani Electricity Mumbai Infrastructure Ltd (AEMIL), spans a total of 80 kilometres, including a 30-kilometre overhead line and a 50-kilometre underground corridor. Designed to operate within one of India’s most densely populated urban zones, the transmission system also features the world’s first compact HVDC substation, showcasing advanced engineering innovation.
The initiative was conceived in response to the 2020 Mumbai Power Outage, which exposed vulnerabilities in the city’s electricity network. The new HVDC link is aimed at enhancing grid resilience, reliability, and the ability to manage large-scale power demands in a rapidly growing metropolitan region.
At its core, the Kudus–Aarey HVDC link allows Mumbai to draw greater volumes of electricity from outside the city, including renewable energy generated in distant regions. While Mumbai is already integrated with the national grid, this advanced transmission corridor enables more efficient, stable, and controlled power flows, particularly critical for renewable energy integration.
For the energy-intensive MMR, the addition of 1,000 MW capacity significantly reduces dependence on in-city power generation. It also mitigates risks of widespread outages, strengthens grid stability, and supports the region’s long-term sustainability goals. As electricity demand continues to rise, such infrastructure is vital for ensuring uninterrupted supply and maintaining economic growth.
A key technological highlight of the project is the deployment of Voltage Source Converter (VSC)-based HVDC systems. This cutting-edge technology allows faster response times, precise control over electricity flows, and enhanced voltage stability. It is especially suited for urban environments where space constraints and grid complexity pose operational challenges.
The HVDC system also brings several operational advantages, including reduced transmission losses over long distances, dynamic voltage support, and black-start capability. The latter ensures that power can be restored quickly without relying on external sources, significantly improving emergency response during outages.
Industry experts note that the Kudus–Aarey link ranks among the largest urban HVDC infeeds globally. It is expected to increase the share of clean energy in Mumbai’s power mix, aligning with India’s broader decarbonisation targets while easing pressure on existing infrastructure.
Commenting on the milestone, AESL CEO Kandarp Patel said the project represents one of the fastest HVDC implementations globally. He emphasized that the new transmission corridor will enhance grid stability, decongest existing networks, and strengthen energy security for Mumbai.
