Textile firm Bombay Dyeing and Manufacturing Company has commissioned a 2.5 MW rooftop solar project at its Rasayani facility in Maharashtra, aiming to reduce energy costs, enhance reliability, and improve long-term sustainability of its manufacturing operations.

The system, installed at the company’s polyester and textile manufacturing unit in Patalganga, was executed by B. U. Bhandari Energy under a capital expenditure model.

The installation is expected to generate approximately 3.6–3.8 million units of electricity annually, reducing electricity costs by around 35–40%. The project is estimated to deliver lifetime savings of ₹450 million (~$4.9 million) to ₹500 million (~$5.4 million), depending on tariff escalation.

The rooftop system comprises Jinko’s 4,107 bifacial solar modules, each rated at 585 Wp, along with Growatt inverters. The installation spans approximately 15,000–16,000 square meters and uses a short rail mounting structure optimized for industrial rooftops.

Bombay Dyeing operates energy-intensive manufacturing processes that require a continuous and reliable power supply. The solar project is expected to significantly reduce reliance on grid electricity, improve energy cost predictability, and enhance energy security amid rising grid tariffs.

In addition to financial benefits, the installation is estimated to offset around 3,000–3,200 tons of carbon dioxide emissions annually, supporting the company’s sustainability goals and cleaner production practices.

B.U. Bhandari Energy designed the system to align with the facility’s load profile and maximize generation within the available rooftop space by using bifacial modules and an optimized layout.

The project was executed in phases to ensure adherence to timelines despite challenges such as monsoon conditions and complex logistics across large rooftop areas. Careful planning, weather protection measures, and cross-team coordination enabled completion without disrupting plant operations.

B.U. Bhandari Energy recently installed two rooftop solar systems totaling 705 kW for Pune Polymers, a plastic components manufacturer, across its manufacturing facilities in Maharashtra.
