A report on Renewables Integration in India 2021 was jointly launched by Dr Rakesh Sarwal, Additional Secretary, NITI Aayog and Keisuke Sadamori, Director of Energy Markets and Security, IEA. The report is based on the outcome of three states workshops held with the Governments of Maharashtra, Karnataka and Gujarat to understand the specific energy transition challenges faced by these renewable-rich states. The report uses IEA modelling results to show the effects of different flexibility options on the power system.
The report highlights that India’s power system can efficiently integrate renewables (175 GW by 2022 and 450 GW by 2030), but it would require identification of resources and proper planning, regulatory, policy and institutional support, energy storage and advance technology initiatives.
Indian states need to employ a wide range of flexible options – such as demand response, more flexible operation of coal-based power plants, storage, and grid improvements – to transition to cleaner electricity systems. Larger shares of renewables can be better managed by shifting the time of use in agriculture. Time of Use (ToU) tariffs will be an effective tool to incentivise demand-side management and encourage flexible consumption.
Sadamori indicated that the joint report underscores IEA’s commitment to providing support to India with its clean energy transition agenda.
Launching the report, Dr Sarwal said that the joint report provides useful suggestions for the states to consider to best manage their integration challenge.
Vivek Kumar Dewangan, Additional Secretary, Ministry of Power said that the report on renewables integration will serve as a repository of vast knowledge for stakeholders in India. He highlighted the government’s policies on thermal power plant flexibility and strengthening of transmission networks through green corridors and stressed the need for cost-effective solutions for storage technologies.
Dinesh Waghmare, Principal Secretary (Energy), Government of Maharashtra, stated that the Ministry of Power proposed Market Based Economic Dispatch (MBED) model for better optimisation of scheduling and economic dispatch of generation capacities purely on economic principles which will replace the current practice of Self Scheduling by Discom.
Dr N Manjula, MD, Karnataka Power Transmission Corporation emphasised that to absorb maximum RE power, the state has shifted 70 per cent to 80 per cent agriculture load to the daytime, providing incentives to industrial consumers for consuming more electricity and increasing state share in the Green Energy Trading (now, approx. 50 per cent). All these measures have helped to reduce the curtailments, which is almost zero now. The Government of Karnataka is in the process of bringing in a new RE policy.
KVS Baba, CMD, POSOCO stated that RE integration can start with proper resources planning and better implementation of technologies, such as Artificial Intelligence, base power system management and smart grid intervention.
