The Union Territory of Dadra & Nagar Haveli and Daman & Diu (DNH-DD) is widely recognized as one of the most heavily industrialized zones in Western India. Because the region hosts thousands of massive manufacturing plants and heavy industries, the local administration generates an enormous amount of revenue from commercial power tariffs. This creates a fascinating and highly beneficial situation for residential households.
The 1 unit electricity price in DNH and DD is quite literally among the absolute lowest in the entire country. The administration heavily cross-subsidizes domestic consumers using industrial revenue. Your household power starts at a staggering low of just ₹1.60 per unit, and the maximum penalty rate caps out at merely ₹3.60 per unit. Furthermore, the mandatory fixed charges are almost negligible.
In this incredibly detailed, beautifully formatted, and deeply researched 1500-word guide, we will completely break down the official FY 2026-27 domestic tariff slabs for DNH-DD. We will explain exactly why the ₹10 per-kW fixed charge is a massive advantage over neighboring states, demystify the 5% electricity duty, and provide you with highly effective strategies to optimize your home’s energy usage to keep your already low bills near zero.
Understanding the Incredible DNH-DD Telescopic Slab System
The electricity distribution administration in DNH-DD utilizes a four-tier “telescopic” slab pricing model for domestic households. This telescopic nature means your monthly electricity bill is not calculated at a single flat rate. Instead, your consumption is divided into highly subsidized blocks. Your first 50 units form the absolute cheapest base block, and the per-unit cost increases progressively—but very gently—as you cross into the higher tiers.
Compared to states like Maharashtra (where the top slab can exceed ₹13 per unit) or Gujarat (which has heavy fuel surcharges), DNH-DD’s tariff structure feels almost like free electricity. Here is the official breakdown of the standard domestic electricity rates:
📊 DNH-DD Domestic Tariff Slabs (FY 2026-27)
| Monthly Consumption Slab | Base Energy Rate (per unit) |
|---|---|
| 0 – 50 Units | ₹ 1.60 |
| 51 – 200 Units | ₹ 2.20 |
| 201 – 400 Units | ₹ 2.90 |
| Above 400 Units | ₹ 3.60 |
⚡ The Unbelievably Low Fixed Charge Advantage:
Fixed Charges in DNH-DD are calculated based on your “Sanctioned Load” (your official connection capacity). For domestic consumers, this is fixed at an unbelievably low ₹10.00 per kW per month. For context, residents in neighboring states often pay between ₹80 to ₹150 per kW. If you have a massive 5 kW connection to run multiple air conditioners in Daman, your mandatory fixed charge is merely ₹50 every single month!
Step-by-Step Billing Calculation Example
To truly understand how these incredibly cheap telescopic slabs apply to your meter reading, let’s look at a practical, real-world calculation. Assume you live in a large 4BHK home in Silvassa with a heavy 5 kW sanctioned load, and you consume exactly 450 units during a hot summer month where you frequently used multiple air conditioners.
Your energy bill is calculated progressively through all four slabs. The first 50 units are billed at the base rate, the next 150 units at the second rate, the next 200 units at the third rate, and the final 50 units spill over into the highest tier. Here is the exact mathematical breakdown:
🧮 450 Units Base Charge Calculation
50 × ₹1.60 = ₹80.00
150 × ₹2.20 = ₹330.00
200 × ₹2.90 = ₹580.00
50 × ₹3.60 = ₹180.00
₹1,170.00
For a massive 450 units of consumption, residents in neighboring states like Maharashtra would easily pay over ₹4,500. In DNH-DD, the raw power cost is a mere ₹1,170. Next, the administration adds your minimal fixed charges and state taxes to this base amount to generate your final payable bill.
The 5% Electricity Duty and Final Bill
The base energy charge of ₹1,170.00 is strictly the cost of the raw power. On top of this, the UT administration levies a small tax to fund grid expansion and administrative overhead.
DNH-DD currently applies a 5% Electricity Duty. It is crucial to understand that this 5% tax is calculated on the combined sum of your Energy Charges AND your Fixed Charges, not just the energy consumed.

Why is Electricity So Cheap in DNH-DD?
If you have recently moved to Silvassa or Daman from states like Gujarat or Maharashtra, you might be shocked at how cheap the electricity is. This is not an error; it is a direct result of the region’s massive industrialization policy.
The UT administration purchases power in bulk from the central grid. Because thousands of heavy manufacturing plants operate 24/7 in the territory, the administration sells massive volumes of electricity to them at higher commercial and industrial tariffs. The profits generated from these corporate giants are then aggressively used to “cross-subsidize” domestic households. This ensures that the local workforce and residents can enjoy incredibly affordable living standards.
5 Proven Strategies to Leverage DNH-DD’s Cheap Tariff
Because the electricity is already so cheap, your strategy in DNH-DD should focus on maximizing comfort without letting the incredibly low rates make you entirely careless with energy consumption.
1. Safely Upgrade Your Sanctioned Load
In states like Haryana, increasing your sanctioned load by 2 kW adds ₹300 to your monthly bill forever. In DNH-DD, because the fixed charge is only ₹10 per kW, upgrading your load by 2 kW to safely support a new heavy air conditioner only costs you an extra ₹20 per month. Do not hesitate to officially upgrade your load to prevent wiring fires; the financial penalty is negligible.
2. Switch to Electric Induction Cooking
Because LPG gas cylinders are becoming increasingly expensive nationwide, and DNH-DD electricity caps at a microscopic ₹3.60 per unit, switching your daily cooking entirely to an electric induction cooktop is actually highly profitable. The cost of the electricity consumed will be drastically lower than the cost of refilling an LPG cylinder.
3. Defend the Massive 400-Unit Boundary
The base rate reaches its maximum of ₹3.60 only when your meter crosses the massive 400-unit mark. The third slab (₹2.90) is extremely wide, covering 200 units. By simply monitoring your smart meter and ensuring you stay below 400 units, you guarantee that you never pay the top-tier rate, no matter how much you run your appliances.
4. Utilize LED Lighting Exclusively
Because the first 50 units are effectively almost free at just ₹1.60 per unit, replacing every single old incandescent bulb or fluorescent tubelight with modern 9W LED bulbs ensures that all your baseline lighting needs are completely absorbed by the cheapest slab, reserving your “expensive” ₹3.60 units strictly for air conditioners and geysers.
5. Invest in Inverter Technology Air Conditioners
While the electricity is cheap, DNH-DD experiences long, humid summers. If you run multiple air conditioners 24/7, you can easily cross 1000 units. Upgrading to 5-star dual-inverter ACs ensures that even if you run the cooling all day, your consumption remains manageable and heavily insulated from the higher tiers.

How much is the Fixed Charge in DNH and DD?
DNH-DD has the most consumer-friendly fixed charge policy in the country. Standard domestic connections are charged an unbelievably low ₹10.00 every single month for every kilowatt (kW) of their officially sanctioned load. A massive 8 kW house pays only ₹80 in fixed charges.
What is the Electricity Duty in DNH-DD?
The UT administration levies a 5% Electricity Duty on all domestic bills. It is critical to note that this 5% tax is calculated on the combined total of your Energy Charges and your Fixed Charges.
Why are the rates so low compared to Gujarat or Maharashtra?
The UT administration heavily relies on the massive revenue generated from the thousands of heavy industries and manufacturing plants located in Silvassa and Daman. This industrial revenue is used to aggressively cross-subsidize the residential sector, keeping domestic rates incredibly low for the local population.
Are commercial electricity rates different in DNH-DD?
Absolutely. Commercial properties, factories, hotels, and retail shops do not benefit from the domestic tariff structure. They are billed under Commercial and Industrial tariff categories, which carry significantly higher base per-unit rates and massive fixed capacity charges, which is precisely what funds the cheap domestic electricity.
