ABSTRACT
Energy modelling can contribute immensely to integrated energy planning and replicate real-world energy systems. As a result, national and even global models can be established. These models can be used to display alternative futures with different fuel supply options. They provide an integrated outlook to the different energy domains of coal, oil, gas, nuclear, and renewables.
Energy modelling in India is fragmented and has limitations. This chapter discusses the challenges and opportunities in using energy models effectively for policy making. Global best practices have been listed to demonstrate the status and importance of energy modelling across the world. Then we share insights gained from national and state-level energy modelling and inter-model comparison exercises to bring out their scope and some areas of opportunities. NITI Aayog has developed an in-house energy optimisation model. A scenario assessment between the baseline and Nationally Determined Contribution (NDC; presented before UNFCCC) scenarios shows that by achieving its targets for increasing renewable capacity per the NDC commitments, India can increase the share of renewables in power generation to 22% by 2032.
