Prayas (Energy Group) has built an open-source, generic, customisable, free-to-use demand-oriented energy systems modelling platform called Rumi, and the PIER (Perspectives on Indian Energy based on Rumi) energy model of India through the decade of the 2020s.

The PIER modelling exercise highlights some interesting trends and policy insights for the Indian energy sector.
* Need for urgent policy attention to increase usage of modern cooking fuels, particularly in some states and regions.
* Small changes in consumer behaviour can significantly impact the country’s energy demand and supply mix.
* Caution in future coal power capacity addition beyond the existing pipeline if India achieves its renewables capacity addition targets.
* Wind can potentially play a greater role vis-à-vis solar in the renewables capacity mix.

The PIER report is available here
