Frequently Asked Questions
Why does Karnataka have higher tariffs than Delhi?
Karnataka has higher electricity tariffs than Delhi due to different subsidy structures, power generation costs, and state government policies. Delhi provides substantial subsidies for residential consumers up to 200 units, while Karnataka has limited free units and higher base rates. Additionally, Karnataka's power generation mix includes more expensive sources, and the state cross‑subsidizes industrial consumers through higher residential rates.
Which Indian state has the cheapest electricity rates in 2025?
Delhi has the cheapest effective electricity rates for residential consumers in 2025, offering up to 200 units free for eligible consumers. West Bengal and Bihar also offer competitive rates with substantial subsidies for lower consumption slabs. However, the 'cheapest' rate depends on your consumption pattern—what's cheap for low usage might not be for high usage.
How do state electricity subsidies work in India?
State electricity subsidies in India vary significantly by state and typically provide free units or reduced rates for initial consumption slabs. For example, Tamil Nadu offers the first 100 units free, Delhi provides up to 200 units free for eligible consumers, and Punjab offers the first 200 units free. These subsidies are funded by state governments and cross‑subsidized from commercial and industrial consumers.
Can I switch my electricity tariff category to save money?
Yes, you can switch electricity tariff categories in most states, but eligibility depends on factors like connection load, usage pattern, and state regulations. Common switches include moving from domestic to commercial tariff for home‑based businesses, or from fixed to time‑of‑day tariffs. Contact your local electricity board to check eligibility and application procedures.
How accurate are online electricity bill calculators?
Online electricity bill calculators are generally accurate when they use the latest official tariff rates and properly account for subsidies, taxes, and surcharges. However, accuracy depends on the calculator being updated with current rates and the user providing correct consumption data. Our calculators are updated regularly with official SERC‑approved tariff schedules.
