Indian Hotels Company Teams Up with Tata Power to Launch a Groundbreaking Energy Storage Solution at Taj Exotica Resort Goa, Paving the Way for Sustainable Hospitality

Published on December 29, 2025

Indian Hotels Company (IHCL) has joined forces with Tata Power to introduce a revolutionary energy storage system at the renowned Taj Exotica Resort & Spa in Goa. This landmark collaboration marks a significant step towards sustainability in the hospitality industry. By integrating one of the most advanced Battery Energy Storage Systems (BESS) with a 2 MW storage capacity, IHCL is setting a new benchmark for sustainable luxury hotels. This innovative solution not only supports the hotel’s energy needs but also contributes to decarbonization efforts, aligning with the broader environmental goals of the Tata Group. With this initiative, the Taj Exotica Resort Goa is paving the way for eco-friendly practices in the hospitality sector, ensuring a cleaner, greener future while delivering unmatched guest experiences.

Indian Hotels Company (IHCL), the largest hospitality chain in India, has launched a groundbreaking project at the Taj Exotica Resort & Spa in Goa in collaboration with Tata Power.

This marks a significant milestone for Tata Power, as it ventures into the hospitality sector for the first time. For IHCL, particularly in Goa, this development holds great significance as it introduces a pioneering energy solution for luxury hotels in the region.

The Taj Exotica Resort & Spa, Goa has successfully integrated one of the hospitality industry’s most advanced Battery Energy Storage Systems (BESS), setting a new standard in sustainable energy management. With an impressive storage capacity of 2 MW, this initiative underscores IHCL’s commitment to decarbonisation as part of its Paathya program and aligns with the Tata Group’s broader Aalingana sustainability vision.

The installation of the BESS was carried out by Tata Power after extensive technical feasibility studies. The total investment in this project is around ₹3.50 crore, with anticipated annual savings of ₹1.50 crore, all while significantly reducing the resort’s reliance on diesel-powered energy sources.

Highlighting the project’s significance, Ms. Sheetal Singh, Area Director – South Goa & General Manager, Taj Exotica Resort & Spa Goa, shared: “Sustainability is at the core of our ethos at Taj Exotica, Goa. The BESS project is an exemplary step in modernising the way hospitality manages energy. By reducing diesel dependence and enhancing power reliability, we are embracing innovation that directly contributes to a greener, more resilient future for our hotel and our community.”

The initiative is expected to reduce approximately 2 lakh litres of HSD annually, dramatically lowering carbon emissions and operational expenditure. Beyond cost reduction, the system improves power quality, minimises generator runtime and reduces air emissions.

Given Taj Exotica’s multi-source power environment that is Grid, Diesel Generators and Solar a sophisticated interlocking and protection system was developed along with Tata Power. This includes automated logic for source prioritisation, prevention mechanisms against backfeed and overload, real-time monitoring and safety cut-offs, thermal, short-circuit and surge protections, emergency shutoff and manual override operations

Comprehensive safety simulations and load-bank tests were conducted to ensure the system operates seamlessly without disrupting guest comfort or electrical stability.

The physical installation of the system was completed in mid-November 2025, marking a significant milestone in the project. Following this, full-load testing was conducted to ensure optimal performance. During the tests, the system demonstrated stable discharge curves and precise switching, validating the robustness of the design and its capacity to meet the anticipated operational demands.

Under the leadership of Athen Chellappa, Area Director of Engineering in Goa, the engineering team performed extensive simulations to assess potential power outage scenarios. This included the validation of automatic DG synchronization, priority-based charging from solar and grid sources, and the accuracy of interlocking and changeover timings. These simulations were essential to confirm that the system would function seamlessly during high-occupancy periods or under peak load conditions, ensuring uninterrupted power supply.

Additionally, the system is equipped with an interactive digital dashboard that offers a comprehensive view of energy flow in real time. This feature provides users with detailed insights into charging status, battery health diagnostics, and predictive maintenance alerts. Historical consumption and savings reports are also available, offering valuable data to optimize energy usage and make informed decisions on future maintenance and energy management strategies.

Indian Hotels Company (IHCL) has partnered with Tata Power to launch a groundbreaking energy storage solution at Taj Exotica Resort & Spa, Goa. The integration of a 2 MW Battery Energy Storage System (BESS) sets a new standard for sustainable luxury. This innovative step supports IHCL’s commitment to decarbonization and aligns with the Tata Group’s sustainability goals, making the resort a leader in eco-friendly hospitality.

Summerising the impact of this initiative, Mr. Ranjit Phillipose, Senior Vice President – Operations, IHCL Goa, says : “The BESS project at Taj Exotica Resort & Spa, Goa is not just an engineering achievement—it is a defining moment in our sustainability journey. By embracing cutting-edge technology and reducing our reliance on fossil fuels, we are setting new benchmarks for responsible luxury. This initiative reflects our belief that the future of hospitality is clean, resilient and climate-conscious, and we are proud to pioneer that change in Goa.”
