Electricity Per Unit Rate in Delhi: BSES & Tata Slabs
If you're checking your Delhi electricity bill and wondering why the per-unit rate seems to jump partway through, here's the direct answer: your electricity per unit rate in Delhi is not one flat number, it rises in slabs from ₹3.00 to ₹8.00 per unit depending on how much you consume in a month, and which of the three DISCOMs serves your area barely changes that structure since all three follow DERC-approved rates.
At a Glance: Delhi Electricity Per Unit Rate 2026
Consumption Slab | Rate per Unit | Who Pays This |
|---|---|---|
0-200 units | ₹3.00 | Small households, heavily subsidised |
201-400 units | ₹4.50 | Mid-size households |
401-800 units | ₹6.50 | Higher consumption, no subsidy |
800+ units | ₹7.00-₹8.00 | Large homes, AC-heavy usage |
Sources differ slightly on the exact split above 800 units. One tracker lists a flat ₹8.00 for everything above 800 units, while another shows an intermediate ₹7.00 slab for 800-1,200 units before ₹8.00 kicks in above that. Verify the exact slab boundary with your DISCOM's published tariff order at publish time, since DERC revises these periodically.
Electricity Unit Rate in Delhi by DISCOM: Does It Actually Differ?
You might assume BSES Rajdhani, BSES Yamuna, and Tata Power charge different rates since they're separate companies. They don't, not meaningfully. All three operate under Delhi Electricity Regulatory Commission (DERC) approval, and the domestic (LT-1) slab structure is identical across them. What differs is the area each one covers, not your rate.
DISCOM | Coverage Area | Domestic Slab Structure |
|---|---|---|
BSES Rajdhani (BRPL) | South & West Delhi | Same DERC slabs |
BSES Yamuna (BYPL) | East & Central Delhi | Same DERC slabs |
Tata Power Delhi (TPDDL) | North & North-West Delhi | Same DERC slabs |
So if you're comparing "BRPL vs BYPL rates" hoping to find a cheaper option, you won't find one by switching, since you can't choose your DISCOM anyway. Your area of residence determines it.
What's Added on Top of the Per-Unit Rate
Your bill isn't just units × rate. Four other charges stack on top, and this is where a lot of confusion comes from when your bill total doesn't match a simple slab calculation.
- Fixed charges: ₹20-₹125 per month depending on your sanctioned load and DISCOM (this varies more than the energy rate does).
- Meter rent: ₹10-₹30 per month.
- Electricity duty: roughly 5% of your energy charges, a state tax.
- PPAC (Power Purchase Adjustment Charge) or FAC surcharge: this is the volatile one, and as of mid-2026 it has been running as high as 17.43% on some bills. This surcharge reflects the DISCOM's fuel and power purchase costs and changes quarterly.
That PPAC surcharge is the fact most bill comparison pages skip past, and it's often the real reason your bill jumped even though the base per-unit rate didn't change. If you want the full formula behind how these charges combine into your final bill, see our guide on how to calculate your electricity bill.
The Subsidy That Reduces Your Effective Rate
Delhi's government subsidy scheme softens the lower slabs further. If your consumption stays at or under 200 units a month, you get a credit that can bring your bill close to zero. Between 201-400 units, you get a 50% rebate on the first 200 units in one version of the scheme, or a flat ₹100 credit in another, depending on which billing cycle rules apply. This means your effective per-unit rate in the lowest bracket is often lower than the ₹3.00 headline rate suggests.
The catch: cross 400 units in a month and the subsidy disappears entirely for that billing cycle, not just for the units above 400. That's a cliff, not a gradual taper, and it's the detail most bill-estimator tools don't flag clearly.
Pros and Cons of Delhi's Slab System
Pros:
- Heavily favours low-consumption households, genuinely useful subsidy for small families
- Uniform structure across all three DISCOMs removes confusion about "which provider is cheaper"
- Transparent, DERC-published tariff orders are publicly available for verification
Cons:
- The subsidy cliff at 400 units penalises households that are just slightly above the threshold
- PPAC/FAC surcharges are unpredictable quarter to quarter and can add double-digit percentage jumps
- Slab boundaries and subsidy amounts get revised periodically, so a rate you saw last year may already be outdated
Who This Rate Structure Works Well For (and Who It Doesn't)
Strong fit for low bills: households under 200 units a month benefit the most, since the subsidy plus the lowest slab rate keeps bills minimal.
Marginal: households sitting right around 380-420 units a month should actively monitor consumption, since crossing 400 units removes the subsidy for the entire cycle, not just the excess units.
Where the rate structure hurts: AC-heavy households easily cross into the 401-800 or 800+ slabs during summer months, where the per-unit rate more than doubles compared to the base slab, plus a heavier PPAC surcharge burden. If that's you, it's worth reading how much rooftop solar could offset that specific spike, starting with a 1kW solar panel price in India breakdown to see what a small system actually costs.
How to Check Your Exact Rate
- Identify your DISCOM from your last bill (BRPL, BYPL, or TPDDL).
- Note your average monthly consumption from the past 3 bills.
- Match that consumption against the current DERC slab table (rates above, verify at publish since DERC revises periodically).
- Add fixed charges, meter rent, electricity duty (~5%), and the current PPAC surcharge to estimate your total bill, not just units × rate.
- Check if you're enrolled in the subsidy scheme through your DISCOM's portal, since it's opt-in for some categories.
FAQs
What is the electricity per unit rate in Delhi in 2026?
Delhi's electricity per unit rate ranges from ₹3.00 for the first 200 units to ₹7.00-₹8.00 for consumption above 800 units, under DERC-approved slabs common to all three DISCOMs.
What is the electricity unit rate in Delhi for BSES customers?
BSES Rajdhani and BSES Yamuna both follow the same DERC-approved slab rates as Tata Power Delhi, since all three DISCOMs operate under identical tariff orders for domestic consumers.
Does the per-unit rate differ between BRPL, BYPL and TPDDL?
No. All three follow the same DERC domestic tariff slabs. What differs is the geographic area each DISCOM serves, not the rate you pay.
Why is my Delhi electricity bill higher than units times rate?
Your bill includes fixed charges, meter rent, roughly 5% electricity duty, and a PPAC/FAC surcharge that has run as high as 17.43% in mid-2026. This surcharge is the most common reason bills exceed a simple slab calculation.
What happens if I cross 400 units in a month in Delhi?
The government subsidy for that billing cycle is voided entirely, not just for units above 400. This is a cliff, so households near the threshold should monitor consumption closely.
Is there a subsidy on electricity bills in Delhi?
Yes. Consumers using up to 200 units get a credit that can bring bills close to zero, and the 201-400 unit bracket gets a partial rebate. The subsidy stops if consumption exceeds 400 units in that cycle.
How much is the fixed charge on a Delhi electricity connection?
Fixed charges range from roughly ₹20 per month for a 2kW connection up to ₹100-₹125 for higher sanctioned loads, varying by DISCOM.
How can I reduce my electricity bill in Delhi if I keep crossing 400 units? Rooftop solar is the most direct fix for households consistently in the 400+ unit slabs, since it reduces grid consumption before the higher tariff and surcharge apply. A 2-3kW system typically offsets a meaningful share of AC-season consumption.
