As of my last knowledge update, Tata Power does not publicly advertise a referral program. The company primarily focuses on delivering energy solutions and services while also exploring initiatives to enhance customer engagement and satisfaction. Referral programs can vary over time and may be introduced in specific campaigns or as part of promotional activities. It is advisable to regularly check the official Tata Power website or related customer communication for any updates regarding promotional programs, including any potential referral initiatives. Information related to current offerings can typically be found on their website, which includes the latest announcements, services, and customer engagement strategies.
