2026 Billing Insights
In 2026, the Punjab and Delhi governments continue their free electricity schemes for domestic loads. If your usage is ≤300 units/month, the energy charge is waived, though fixed charges may still apply in some categories.
New for 2026 in states like Gujarat and California, ToU billing gives you a discount (e.g., 60 paise in Gujarat) for using power during solar peak hours (11 AM – 4 PM) and surcharges during evening peak hours.
States like Tamil Nadu bill every 2 months. This calculator normalizes the bi-monthly slabs into monthly equivalents (e.g., a 1000-unit bi-monthly slab becomes a 500-unit monthly slab) for consistent calculation.
