Strengthened grids: A case of electric vehicles in Bengaluru
The HinduIndia pledged to reach net zero emissions by 2070 at the 26th Conference of the Parties held at Glasgow recently. However, higher EV penetration may pose destabilisation threats to the grid with its spatial and temporally uncertain nature, by causing significant peaks when coinciding with residential peak demand. As per an India Smart Grid Forum study for twelve 11kV feeders in Bengaluru, significant upgradation on the DTs and cables are required for smooth integration of the EV load, along with filter installation to mitigate the harmonics issues. This should also be complemented by introducing a time-of-day tariff for Bengaluru EV owners by incentivising with lower charging tariff during off-peak and disincentivising with higher charging tariffs during peak demand. Leveraging its potential of RTPV uptake along with strong distribution infrastructure investments could help Karnataka achieve its 2030 EV goals.
