A state-of-the-art, 625 KW rooftop solar plant was recently commissioned by Jakson at a Tata Cummins manufacturing plant in Phaltan, Maharashtra. The plant generates about 10 lakh units of green electricity annually, which is used for running plant operations. This translates into a saving of about INR 30 lakhs per annum in electricity costs as well. Jakson provided complete turnkey engineering, procurement and construction (EPC) services for the project. The project was executed under CAPEX model, where the roof owner is the owner of the rooftop solar system and bears the entire capital expenditure of the project. In addition to turnkey execution, Jakson will provide annual operations and maintenance services.

  • PV module power rating: 315 Wp
  • Annual generation capacity: 1,000,000 KWh approx.
  • Annual electricity cost savings: INR 28 - 30 lakhs
  • Annual carbon emissions offset: 750 tons approx.


Tata Cummins Pvt Ltd is a 50:50 joint venture between Tata Motors Limited, and Cummins Inc., USA, dedicated towards manufacturing of high performance, reliable and durable mid-range engines in the 75 to 400 HP range that not only comply with current and future emission norms, but are also serviceable globally.

Established in the year 1994, the company started its operations with its state-of-the-art facility at the steel city of Jamshedpur. Over the years, the company has expanded with the setting up of two more manufacturing facilities at the Cummins Megasite in Phaltan, Maharashtra.

Business need

Educational institutes with modern infrastructure require significant amounts of electricity for their day-to-day operations. With ever increasing electricity costs, solar rooftop power plants has emerged as an ideal solution to save on electricity costs.

With more than 100,000 square metres of covered area, the main building of Hindustan College of Science and Technology had abundant vacant rooftop space which was ideal for setting up of a rooftop solar power plant. Enabled with net metering, the power generated

would supplement the institute’s electricity requirements and potentially cut down on electricity costs.


Jakson provided complete turnkey EPC services for this project that included supply, erection, testing, commissioning including warranty, operations and maintenance. A total of about 2000 highly efficient polycrystalline solar PV module of 315 Wp rating was installed in the plant along with all other requisite items of a solar rooftop installation.

The plant generates approximately 10 lakh units of green electricity every year. The power generated is mainly used for routine plant operations like lighting, running factory equipment, etc. The plant is also enabled with net-metering facility which will allow for selling of excess power to the grid resulting in an estimated annual savings in the range INR 30 lakhs. Additionally, the plant will also help offset about 750 tons of carbon emissions per year.
