Tata Power Renewable Energy Limited (TPREL) has launched a Pay-as-You-Save rooftop solar scheme in Ludhiana that enables commercial and industrial consumers across Punjab to install systems without any upfront capital investment. The move is part of TPREL's Sustainable Edge initiative and is intended to accelerate rooftop adoption by removing high initial cost barriers. The company plans to install 200 megawatt (MW) of rooftop solar capacity across Punjab's commercial and industrial segment over the next three years. The financing model allows businesses to repay system costs through affordable monthly EMIs or lease rentals that are linked to projected savings from solar generation, aligning repayments with expected energy output to support cash flow. The scheme offers access to the SunSmart Flexi EMI programme, which provides collateral-free financing, competitive interest rates, flexible repayment tenures and a fully digital approval process. This structure is designed to reduce financial strain while supporting the transition to cleaner energy sources. Punjab hosts major industries such as textiles, bicycle manufacturing, engineering goods, auto components, foundries, food processing and agricultural equipment, many of which are energy intensive. TPREL said the initiative aims to help these sectors manage rising electricity costs, improve operational efficiency and meet corporate sustainability goals through renewable adoption. The company also noted an existing presence in the state with 6,661 rooftop solar installations to date. Alongside the financing proposal, TPREL showcased its Battery Energy Storage Systems (BESS) portfolio under the Tata Power Battery Storage brand, describing storage options that span from five kilowatt hour (kWh) to 50 megawatt hour (MWh) for residential and commercial applications. The company presented the integrated offer as a means to enhance energy resilience, enable better load management and capture more of the value from onsite generation. The initiative is intended to support longer term decarbonisation and better cost predictability for industrial and commercial consumers.
