Key figures: electricity in Bihar
In October 2026, Bihar was supplied 148 GWh of electricity on an average day, with demand peaking at 8,490 MW on 4 Oct 2026. That is 16.2% more per day than in October 2025.
The highest demand ever met in Bihar since 2023 is 9,475 MW, on 16 Jul 2026.
In the last 365 days, Bihar saw demand go unmet on 145 days, 158.1 million units (MU) in all. The deepest shortage was 11.1 MU on 18 Apr 2026.
Over the last 12 complete months, Bihar met 14% of its demand without drawing from the interstate grid. This is a residual: energy met minus scheduled drawal and deviation, so a central station inside the state that is scheduled through the interstate grid counts as grid supply.
Its load factor, average demand as a share of the month's peak, was 73% in October 2026, against 83% for India as a whole.
