Diu Smart City has become the first city in India to run on 100 percent renewable energy during daytime.
Diu had been importing 73 percent of its power from Gujarat until last year. It has adopted a two-pronged approach and developed a 9 MW solar park spread over 50 hectares rocky barren land besides installing solar panels on the roof tops on 79 government buildings generating 1.3 MW annually.
Diu offers its residents a subsidy of Rs 10, 000-50,000 for installing 1-5KW roof top solar panels. Diu is saving about 13,000 tonnes of carbon emissions every year. Diu has slashed power tariffs for residential category by 10 percent last year and 15 percent this year — due to low-cost solar energy.
