Pimpri: The Pimpri Chinchwad New Town Development Authority (PCNTDA), which had installed the first solar system four years ago, has been successfully using the solar power generated from the project. After connecting this solar system to the MSEDCL’s power grid, the authority succeeded in reducing electricity bills of the project by almost Rs 2.75 lakh per month.
The building, which was constructed by PCNTDA in 2013, has become the first green government building. However, in absence of a power grid facility, it had to invest in batteries to store the solar power generated from the system. But due to reccuring expense on batteries, it was not a profitable project.
The project has been developed in accordance with green building norms. The building incurs minimal need of use of electricity for lighting purpose. It has solar panels installed at various points in its premises. Cumulative power generation capacity of this project is 140 KW. Half of the power for lifts and airconditioners is generated through
Currently, only one wing of the building is occupied by PCNTDA office. Hence, during summers, the power generated by the project is sufficient for the building. Before connecting this system to the power grid, the PCNTDA used to pay Rs 2.75 lakh to 3 lakh as monthly electricity bills.
However, after connecting to the power grid, the bills have reduced to Rs. 10,000 to 15,000.
Prabhakar Vasaikar, Executive Engineer of PCNTDA, said, “At the time of installation of solar panels, the authority spent over Rs 2 crore. The subsidy of Rs 70 lakh was received for the project. We have purchased 480 batteries for storage of electricity generated from the project. But due to heavy incurring investment in batteries, the project was not profitable. However, after net metering policy of the State government, the project has become viable. After this, our building consumes minimal power. On the holidays, the project supplies more power to the grid. That is why the project has become profitable. We hardly pay Rs 10,000 to 15,000 electricity bills these days.
