About Desi Utility
India's most comprehensive free platform for understanding, calculating, and reducing household electricity costs.
Desi Utility.com was built by a team of energy engineers and home appliance researchers who noticed a growing gap — millions of Indian households were struggling with soaring electricity bills without the tools to understand where their money was going. Our platform offers free calculators covering AC bills, electricity tariffs for all 16 DISCOMs, solar ROI, net metering, tonnage sizing, and much more.
Every calculator is built on verified data from the Bureau of Energy Efficiency (BEE), official DISCOM tariff schedules, and real-world testing across Indian climate zones. Our blog and reviews are fully independent — we don't accept payment from brands for positive reviews. We keep all content updated annually for the latest BEE star rating revisions and DISCOM tariff orders.
