Taj Exotica Resort & Spa, Goa inaugurates a landmark sustainability initiative in partnership with Tata Power, becoming the first hotel in India to deploy a Battery Energy Storage System (BESS) within the hospitality sector. This milestone project marks Tata Power’s first-ever BESS implementation in hospitality and reinforces Indian Hotels Company Limited’s (IHCL) commitment to sustainable operations under its Paathya framework, aligned with the Tata Group’s Aalingana sustainability vision.
The luxury resort has installed a BESS with an approximate storage capacity of 2 MW, representing a major step in modernising energy management and reducing carbon impact. Executed by Tata Power following extensive technical feasibility studies, the project involved an investment of approximately ₹3.50 crore and is projected to generate annual savings of nearly ₹1.50 crore. The system is expected to significantly reduce reliance on diesel-based power generation at the resort.
Commenting on the initiative, Sheetal Singh, Area Director – South Goa & General Manager, Taj Exotica Resort & Spa, Goa, said that sustainability remains central to the resort’s ethos and that the BESS project strengthens power reliability while supporting a greener and more resilient future for both the hotel and the surrounding community.
The project is expected to eliminate nearly two lakh litres of high-speed diesel consumption annually, resulting in a substantial reduction in carbon emissions and operating costs. Beyond financial efficiencies, the system enhances power quality, reduces generator runtime and lowers air emissions.
Given the resort’s multi-source energy ecosystem, which includes grid supply, diesel generators and solar power, IHCL and Tata Power jointly developed a sophisticated interlocking and protection architecture. This includes automated source prioritisation, real-time monitoring, safety cut-offs, thermal and surge protections, emergency shutdown systems and manual override capabilities to ensure seamless and safe operations.
Comprehensive safety simulations and load-bank testing were conducted to ensure uninterrupted functioning and guest comfort. The physical installation was completed in mid-November 2025, followed by full-load testing that confirmed stable discharge performance and precise power source switching.
The engineering team led by Area Director Engineering – Goa, Athen Chellappa, carried out extensive simulations of power outage scenarios to validate system responsiveness, generator synchronisation, charging priorities and cloud connectivity. The BESS is supported by an interactive digital dashboard that provides real-time energy flow visibility, battery health diagnostics, predictive maintenance alerts and detailed analytics on consumption and savings.
Ranjit Phillipose, Senior Vice President – Operations, IHCL Goa, stated that the project represents a defining moment in IHCL’s sustainability journey, setting new benchmarks for responsible luxury by reducing dependence on fossil fuels and embracing advanced clean energy solutions.
