See What Solar Could Save You in Odisha
Compare 1kW, 2kW and 3kW rooftop systems using real OERC domestic tariff rates verified from an actual Odisha electricity bill.
Rates based on OERC common domestic tariff, applicable across TPCODL, TPWODL, TPSODL and TPNODL
How This Calculator Works
We built this calculator using the same telescopic slab system that OERC uses to bill every household in Odisha. When you enter your monthly units, we run them through the four tariff slabs exactly the way TPCODL, TPWODL, TPSODL and TPNODL would on your actual bill. That means the savings numbers you see here are not a rough estimate pulled from a generic formula, they follow the real math behind your electricity bill.
For each system size, we calculate how many units your rooftop panels would generate in an average Odisha month, then work out how much of your grid bill that generation would offset. The result is your monthly savings, how many years it takes for the system to pay for itself, and how much carbon dioxide you would keep out of the atmosphere every year. Curious why we use an average instead of a single month's figure? We break down real monsoon versus dry season generation data in this article.
Understanding Your Odisha Electricity Bill
Every domestic connection in Odisha is billed under a telescopic slab system. The first block of units you use each month costs Rs 2.90 per unit, the next block costs Rs 4.70, then Rs 5.70, and anything above that is billed at Rs 6.10 per unit. On top of this, the state adds a 4 percent electricity duty. This structure means the more you consume, the more your last few units cost you, which is exactly why solar makes the biggest difference for households with higher monthly bills.
This slab structure is common across all four Odisha discoms. TPCODL, TPWODL, TPSODL and TPNODL are all run by Tata Power in partnership with the Odisha government, and OERC sets one tariff schedule that applies to all of them. So whether you are in Bhubaneswar, Cuttack, Sambalpur or Berhampur, the rates you see in this calculator apply to your bill too.
A Real Project, Real Numbers
We installed a 9 metre solar high mast system at Kapileswar Temple in Bhubaneswar, and it has been running on solar power alone since. You can read the full breakdown of that project, including the exact panel and battery specs we used, on our solar high mast light page.
