Rise in Electricity Demand in Karnataka Attributed to Growing EV Adoption

India's Electric Vehicle Boom Tests Power Grid

India's accelerating electric vehicle adoption is beginning to leave its mark on the power grid, with Karnataka reporting a sharp increase in electricity consumption and peak demand, as policymakers prepare for EV charging emerging as a major energy driver.

Data from Karnataka's power utilities shows that consumption between April 1 and April 26 zoomed 19.4 percent on-year to 9,101 million units (MU), with peak demand growing to 18,478 MW from 17,330 MW in the year-ago period. This surge in demand reflects the country's growing reliance on electric vehicles, driven in part by fuel-price volatility following geopolitical tensions in West Asia.

As electric two-wheeler registrations rose 41.6 percent year-on-year to 1,49,509 units as of May 29, according to Vahan data, industry executives attributed the growth to discounts, financing schemes and consumers seeking to reduce dependence on petrol-powered vehicles amid fuel-price uncertainty. Karnataka has emerged as one of India's largest EV markets, with state government data showing EV sales have increased nearly 17-fold between FY21 and FY26, while EV penetration has reached 13.65 percent, compared with the national average of 9.12 percent.

Utilities and charging operators are expanding infrastructure to meet demand. Under the PM E-DRIVE scheme, BESCOM has proposed installing 1,250 charging stations in the first phase and another 800 through private charge-point operators. However, charging and battery-swapping infrastructure remain major bottlenecks, industry executives said.

To address this issue, governments should create dedicated charging and swapping hubs with pre-approved power infrastructure. Initiatives such as opening metro stations for battery swapping have helped, but more public spaces and government-owned land should be made available for rapid expansion of EV charging infrastructure.

Smart charging helps utilities shift demand away from peak hours, while vehicle-to-grid (V2G) technology allows EV batteries to supply power back to the grid during periods of high demand. Karnataka is also experimenting with alternative energy solutions, such as a solar-powered EV charging hub near Bengaluru airport that combines a 45-kW rooftop solar installation with a 100-kWh second-life battery storage system and can charge 23 vehicles simultaneously.

The trend mirrors a broader global shift. According to the International Energy Agency (IEA), electricity demand from EVs is expected to exceed 640 terawatt-hours by 2030, accounting for around 4-5 percent of global electricity consumption, underscoring the growing link between transportation and power infrastructure.
