India has 63.3 million Micro, Small, and Medium-Sized Enterprises (MSMEs). 31% of these are manufacturing units, which account for 25 percent of the industrial sector’s energy consumption. Advancing the implementation of clean energy measures in the MSME sector can play a key role in India’s clean energy transition. The aim was to demonstrate the aggregation potential for the solar rooftop PV system in 2 industrial clusters based in Aurangabad, Maharashtra and Naroda, Gujarat in India. We estimated a total of 4 mega-watt peak (MWp) of distributed SRT PV potential in Aurangabad and 1 MWp in Naroda. This practice note captures our experience of working 2 industrial clusters, the processes, barriers and key lessons, which can help advance additional aggregation strategies going forward.
