Goa’s Luxury Resort Goes Green: Taj Exotica Pioneers 2 MW BESS with Tata Power Published By Anupam Nath Taj Exotica Resort & Spa, Goa, has set a new benchmark in sustainable hospitality by installing a cutting-edge 2 MW Battery Energy Storage System (BESS) in partnership with Tata Power. This initiative slashes diesel dependency, cuts emissions, and aligns with IHCL's Paathya decarbonization program and Tata Group's Aalingana vision, proving luxury and green tech can coexist seamlessly.(see the generated image above)Project HighlightsThe BESS, costing around Rs 3.50 crore, promises annual savings of Rs 1.50 crore while reducing high-speed diesel (HSD) use by approximately 2 lakh litres yearly. In Goa's multi-source power setup—grid, diesel generators, and solar—this system prioritizes renewables through smart interlocking. It features automated source switching, real-time monitoring, overload protection, surge safeguards, and emergency overrides, ensuring uninterrupted guest comfort.(see the generated image above)Physical installation wrapped up in mid-November 2025, with full-load tests confirming stable performance. Led by Athen Chellappa, the engineering team simulated outages to validate seamless diesel generator sync and solar-priority charging, minimizing generator runtime and air pollution.(see the generated image above)Leadership InsightsSheetal Singh, Area Director-South Goa and General Manager at Taj Exotica, emphasized: "Sustainability defines our ethos. This BESS modernizes energy management, boosts reliability, and fosters a greener future for our hotel and community." The project enhances power quality, cuts operational costs, and lowers carbon footprints dramatically.(see the generated image above)Technical InnovationTata Power's execution included comprehensive safety simulations and load-bank tests. The sophisticated controls prevent backfeed, manage thermal/short-circuit risks, and enable manual overrides. By storing excess solar energy, the BESS discharges efficiently during peaks, transforming the resort's energy resilience in a diesel-prone region.(see the generated image above)Broader ImpactThis marks a pivotal shift for India's hospitality sector, where luxury properties often rely on fossil fuels. Taj Exotica's model could inspire nationwide adoption, supporting India's renewable goals. With proven ROI and environmental gains, BESS emerges as essential for decarbonizing high-energy venues like resorts
