Rooftop PV and BIPV set to be central theme in India's first Zero Energy Satellite Township


“Each household will have rooftop solar PV modules and BIPV that will be established as micro grids – linking electricity suppliers and consumers to maintain the most secure and cost-effective system – connected to the main transmission grid,” said managing director of the company, Sani Pada Gonchoudhary. He added that streetlights will be lighted using solar PV systems, and that a clean transportation system will be incorporated, using batteries charged by solar PV modules.

The houses will be built using solar passive architecture and water will be heated from solar water heaters. The area already has India's first successfully operating solar housing complex (Rabi Rashmi Abashan) with 36 houses meeting optimal energy using solar power and adopting passive housing structures.

The U.S. Department of Energy (DOE) and Brookhaven National Laboratory (BNL) have said they will jointly initiate efforts for a special project of developing an energy-efficient model township. The West Bengal State urban development department will implement it.

The Central Government has selected Rajarhat as one of the eight upcoming satellite townships of the country that will receive 80 percent of the total cost of implementing civic infrastructure projects. It is anticipated that the township that will house around one million people in future. By the time Rajarhat turns into a ZEST in a few years, it is said that its energy demand will be reduced by between 40 and 50 percent.

Rajarhat, also known as New Town, is a township based on the outskirts of the city Kolkata in eastern India and is spread over an area of 28 km2.
