For most households in Punjab, the electricity bill is either a complete non-issue (resulting in a “Zero Bill”) or a massive financial shock. This sharp divide is entirely due to the state’s famous 300 free units scheme.
Because so many people receive zero bills, there is a common misconception that power is incredibly cheap. In reality, the actual 1 unit electricity price in Punjab for those who cross the subsidy limit is quite high. PSPCL (Punjab State Power Corporation Limited) enforces strict billing “cliffs,” heavy fixed charges, and a massive 18% electricity duty that punishes high consumption.
Let’s break down the official FY 2026-27 tariff rates, explain how the billing cycle affects your subsidy, and clarify the crucial difference between the General Category and the SC/BC Category when crossing the 300-unit mark.
Understanding PSPCL Base Rates
Unlike other states that break consumption down into five or six tiny slabs, Punjab keeps it simple. There are only two base energy slabs for domestic consumers.
📊 PSPCL Domestic Tariff Slabs (Per Month)
| Monthly Consumption Slab | Base Energy Rate (per unit) |
|---|---|
| 0 – 300 Units | ₹ 3.85 |
| Above 300 Units | ₹ 7.05 |
⚡ Monthly Fixed Charges (Per kW):
- Up to 2 kW: ₹35/kW
- Above 2 to 7 kW: ₹55/kW
- Above 7 to 20 kW: ₹85/kW
- Above 20 kW: ₹105/kW
The Harsh Reality: 18% Electricity Duty
The base rate of ₹7.05 for higher consumption is already steep, but the real pain comes from state taxes. The Punjab Government currently levies an enormous 18% Electricity Duty on the total sum of your energy charges and fixed charges.
Additionally, PSPCL adds a variable Fuel Surcharge (currently around ₹0.10 per unit) to recover coal and generation costs.
Because of this massive 18% tax, a base rate of ₹7.05 effectively becomes over ₹8.30 per unit once taxes are applied. This is why summer bills in Punjab escalate so rapidly for AC users.
The 300 Free Units Subsidy: How It Actually Works
The core of Punjab’s billing system revolves around the 300-unit monthly subsidy. However, PSPCL bills most domestic consumers on a Bi-Monthly (once every two months) cycle. Therefore, the subsidy limit on your physical bill is usually calculated as 600 units for two months.
The way this subsidy behaves when you cross the limit depends entirely on your registered category.
1. General Category (The “All or Nothing” Cliff)
If you are in the General Category, the subsidy is strictly “all or nothing.”
- If you consume exactly 600 units in two months (300/month), your base charges, fixed charges, and taxes are completely waived. Your bill is ₹0.
- If you consume 601 units, you lose the subsidy entirely. You are billed for all 601 units at the standard slab rates, plus full fixed charges, plus the heavy 18% tax.
Example: Consuming 600 units results in a ₹0 bill. Consuming 601 units results in a bill of approximately ₹3,500. That single extra unit effectively costs you ₹3,500.
2. SC / BC / BPL Category (The “Excess Only” Rule)
The government provides a much more forgiving structure for Scheduled Castes, Backward Classes, BPL families, and Freedom Fighters.
- If you consume up to 600 units (bi-monthly), your bill is ₹0.
- If you consume 601 units, you only pay for the 1 extra unit. The first 600 units remain completely free.
- This eliminates the massive billing cliff, ensuring that crossing the limit only results in a small, proportionate bill.

Commercial and Industrial Tariffs in Punjab
Businesses and industries in Punjab operate on a flat-rate system. They do not receive any free units, but the state has tried to keep industrial rates relatively competitive.
Commercial (Non-Residential Supply – NRS)
Shops, malls, and offices pay a high flat rate, coupled with the heavy 18% electricity duty.
Flat Energy Rate
₹7.00/unit
Fixed Charge
₹105/kW/mo
Small Power (Industrial)
To promote local manufacturing, small industrial connections are offered a significantly lower energy rate compared to commercial shops.
- Energy Rate: Flat ₹5.30 per unit
- Fixed Charge: ₹115 per kW per month
EV Charging Stations
Electric vehicle charging infrastructure enjoys a subsidized flat rate with absolutely zero fixed charges, encouraging EV adoption across the state.
- Energy Rate: Flat ₹6.00 per unit
- Fixed Charge: Nil (₹0.00)
3 Proven Ways to Lower Your Punjab Electricity Bill
| Strategy | Why it works in Punjab |
|---|---|
| Defend the 600-unit Bi-Monthly Line | If you are in the General Category and your meter reads 580 units with two days left in the cycle, turning off the ACs will literally save you ₹3,500. Monitor your meter closely. |
| Verify Your Category Status | If you belong to SC/BC or BPL categories but are still registered as General in the PSPCL system, you are exposing yourself to the massive billing cliff. Update your records at the local sub-division office. |
| Audit Your Sanctioned Load | If your bill crosses the subsidy limit, you pay full fixed charges. Lowering an unused 10 kW sanctioned load to 5 kW saves you ₹55 per kW every month, plus avoiding the 18% tax on that amount. |
Frequently Asked Questions
What is the 1 unit electricity price in Punjab for homes?
PSPCL has two domestic slabs. The first 300 units are billed at a base rate of ₹3.85, and anything above 300 units is billed at ₹7.05. However, due to the 18% electricity duty and fuel surcharges, the effective top rate is over ₹8.30 per unit.
How many units are free in Punjab?
The Punjab Government provides 300 free units per month to domestic households. Since billing is usually done every two months (bi-monthly), the limit on your physical bill is 600 units.
What happens if my bill crosses 600 units (bi-monthly) in Punjab?
If you are in the General Category, you lose the entire subsidy. You must pay for all 600+ units at normal rates, plus taxes. If you are in the SC/BC/BPL category, you only pay for the units consumed above the 600-unit mark.
How much is the electricity duty in Punjab?
Punjab levies an incredibly high 18% Electricity Duty on the sum of your base energy charges and fixed charges. This is one of the highest duty percentages in India.
Does a commercial shop get the 300 free units?
No. The 300 free units scheme applies strictly to domestic (residential) connections. Commercial shops pay a flat rate of ₹7.00 per unit plus fixed charges and taxes from unit one.
Is the billing cycle in Punjab monthly or bi-monthly?
While commercial and high-load connections often receive monthly bills, the vast majority of standard domestic households in Punjab receive their bills bi-monthly (once every two months).
