Press Release: Switch on, smoke off: Reducing emissions from diesel generator sets

Many districts in Rajasthan, Uttar Pradesh, West Bengal, and Maharashtra show high PM2.5 emissions, driven by high installed capacities of DG sets and frequent power cuts.
Patna (Bihar), Gautam Buddha Nagar (Noida), Bengaluru Urban (Karnataka), Mumbai City (Maharashtra), and North 24 Parganas (West Bengal) have the highest PM2.5 emissions from DG sets.
The Indian DG set market is projected to grow at a compound annual growth rate (CAGR) of 8.8% by 2030.
Solar photovoltaic systems with storage offer 100% emission reduction potential but currently only meet about 30% of the DG set demand, owing to high costs and land needs.
Natural gas generators can offer a reduction of over 95% in primary PM2.5 emissions. However, key challenges include high initial costs, a poor network of gas pipelines in remote areas, and safety risks.
