Ministry Sets Ambitious 43.3% Renewable Energy Target for 2030, Emphasizes 41.13 GW Battery Storage and 18.6 GW Pumped Hydro

In a significant move towards bolstering renewable energy adoption, India’s Ministry of Power has mandated that each state must progressively increase the percentage of its electricity consumption derived from renewable energy sources. The targets will escalate from 24.3% in 2023 to an ambitious 43.3% by 2030. This directive aims to propel India towards its climate action goals, as emphasized in a recent policy paper by NITI Aayog. The paper, authored by Venugopal Mothkoor, Dr. Anjali Jain, and Rajnath Ram, delves into state-wise planning and capacity requirements necessary to meet these targets.

Central to this initiative are the Renewable Purchase Obligations (RPOs), which obligate Distribution Companies (DISCOMs) in each state to ensure a specified portion of their electricity supply comes from renewable sources. The policy paper underscores the critical role of these obligations in driving the transition to a more sustainable energy landscape.

The report also provides an in-depth analysis of the storage capacity required to support the integration of renewable energy into the grid. Utilizing the TIMES-VEDA optimization tool, the study estimates the necessary storage at a regional level. It projects that by 2029-30, around 18.6 GW of Pumped Hydro storage will be available to help balance the variable input from renewable energy sources. In addition, a 5-hour Battery Energy Storage System (BESS) is identified as a vital mechanism for further balancing the grid.

The total BESS capacity required for a 5-hour duration is estimated at 41.13 GW, complementing the 18.6 GW from Pumped Hydro. The storage requirements are broken down regionally, with the Northern Region needing 17.043 GW, the Southern Region 2.74 GW, the Eastern Region 9.40 GW, the Western Region 11.742 GW, and the North-eastern Region requiring a modest 0.208 GW.

This comprehensive strategy highlights the intricate planning and substantial investment needed to transition India’s energy infrastructure towards a more renewable and sustainable future. The full details and implications of this policy can be found in the NITI Aayog’s report.
