India’s CEC wants EVs to be used for energy storage to support national grid

Must read

The Central Electricity Authority (CEA) wants electric vehicles (EVs) to be used for energy storage in a bid to support the national grid, ET Energy reported, citing a CEA report.The report, prepared with contributions from experts at IIT Bombay, IIT Delhi, and IIT Roorkee, among others, envisions a future where EVs can support the grid by offering services like peak shaving and load balancing.

Emphasising the significance of smart charging and vehicle-to-grid (V2G) services, the CEA report said that EVs can be used as flexible loads and decentralised storage resources, providing additional flexibility to support power system operations.

“With smart charging, EVs could adapt their charging patterns to flatten peak demand, allow valleys and support real-time balancing of the grid by adjusting their charging levels,” the CEA report stated.

According to the report, the parked EVs also have massive potential. The report stated that the parked EVs remain idle for 80–90% of their lifetime and have vast electricity storage capacity.

The report said that smart charging infrastructure could facilitate the seamless integration of renewable energy and advocated for supportive regulatory policies for sustainable EV charging systems. The CEA noted that the decreasing costs of renewable power generation make electricity an economically viable fuel for the transport sector. Additionally, EVs’ ability to store and return energy to the grid offers valuable flexibility for power system operations. However, the report acknowledges challenges such as rising peak demand, grid congestion, and the need for infrastructure upgrades to accommodate high-power chargers. It identifies key components for successful implementation of V2G services, including technology standards, electric load management strategies, battery swapping, and advanced metering infrastructure. To overcome these challenges, the CEA recommends the adoption of standardised practices, interoperability, bidirectional charging systems, and robust communication networks between mobility and the grid.
