Cricket is the most popular sport in India, and the M. Chinnaswamy Stadium in Bangalore one of the country’s best-known cricket stadiums. On match days, up to 40,000 spectators come to the stadium, which was built in 1970. Now the M. Chinnaswamy Stadium has now been converted into a ‘green’ stadium.The project was completed in just 50 days.
A 400kW Grid Interactive Solar Power Plant has been installed on the roof of the stadium. As per the design, this grid can easily power the entire stadium lighting except the huge high-intensity floodlights.
The stadium spends around Rs 1 to Rs. 1.2 crores on electricity bills for using about 18 lakh units of power annually. The new initiative will bring down this cost significantly and is expected to generate 6 lakh units of solar power annually, utilizing a portion of it and also selling the surplus.
A modern plant installed on the roof of one of the stands helps collect up to 35 million litres of rainwater every year, which can be used for the sanitary facilities or to water the playing field. An optimised waste disposal system ensures that the trash left behind by spectators is disposed of in an eco-friendly manner and recycled. A solar system on the roof of the eastern stand provides clean energy for the visitor areas and for the changing rooms. The M. Chinnaswamy Stadium is the first cricket stadium in the world to be powered by solar energy.
The project, costing Rs. 4.5 crore, was commissioned in February this year and KSCA(Karnataka State Cricket Association) is expected to break even in just four years. Not only this, it will also be able to generate revenues of Rs. 70-80 lakhs every year with the power it generates.
The maintenance of solar systems, such as the one in the Bangalore stadium, is cost-effective, and surplus energy from the roof of the stand can be fed directly into the city’s power grid. While the installation costs will be recouped in just four years, the environment is already benefiting, as the use of solar energy helps save 600 tonnes of CO2 per year.
