Taj Exotica Resort & Spa, Goa has inaugurated a landmark sustainability project in partnership with Tata Power, marking the company’s first-ever Battery Energy Storage System (BESS) deployment within the hospitality sector. The project also positions Taj Exotica as the first hotel in India to adopt this advanced energy solution.
The luxury resort, part of Indian Hotels Company Limited, has successfully implemented BESS installations in the hospitality industry, with an approximate storage capacity of 2 MW. The initiative represents a significant milestone in IHCL’s decarbonisation strategy under Paathya and aligns with the Tata Group’s Aalingana sustainability vision.
Executed by Tata Power following extensive technical feasibility studies, the project involved an investment of approximately ₹3.50 crore and is projected to deliver annual savings of nearly ₹1.50 crore. The system is expected to substantially reduce the resort’s dependence on diesel-based power generation.
Commenting on the initiative, Sheetal Singh, Area Director – South Goa & General Manager, Taj Exotica Resort & Spa, Goa, said, “Sustainability is at the core of our ethos at Taj Exotica, Goa. The BESS project is a strong step towards modernising energy management in hospitality. By reducing diesel dependency and improving power reliability, we are contributing to a greener and more resilient future for our hotel and the community.”
The project is expected to eliminate nearly two lakh litres of high-speed diesel (HSD) consumption annually, significantly lowering carbon emissions and operating costs. In addition to cost efficiencies, the system enhances power quality, reduces generator runtime, and cuts air emissions.
Given the resort’s multi-source power ecosystem—comprising grid supply, diesel generators, and solar energy—a sophisticated interlocking and protection architecture was jointly developed by IHCL and Tata Power. This includes automated source prioritisation, prevention of backfeed and overload scenarios, real-time monitoring, safety cut-offs, thermal and surge protections, emergency shutdowns, and manual override capabilities.
Comprehensive safety simulations and load-bank testing were carried out to ensure uninterrupted operations and guest comfort. Physical installation was completed in mid-November 2025, followed by full-load testing that confirmed stable discharge performance and precise source switching.
The engineering team, led by Area Director Engineering – Goa, Athen Chellappa, conducted extensive simulations of power outage scenarios to validate automatic diesel generator synchronisation, priority-based charging from solar and grid sources, interlocking accuracy, changeover response times, and cloud connectivity critical for system operations. The BESS is supported by an interactive digital dashboard offering real-time energy flow visibility, battery health diagnostics, predictive maintenance alerts, and detailed consumption and savings analytics.
Ranjit Phillipose, Senior Vice President – Operations, IHCL Goa, said, “The BESS project at Taj Exotica Resort & Spa, Goa is more than an engineering achievement—it represents a defining moment in our sustainability journey. By adopting advanced technology and reducing reliance on fossil fuels, we are setting new benchmarks for responsible luxury and reinforcing our commitment to a clean, resilient, and climate-conscious future.”
