Punjab Official Tariff: Active for 2026 (Valid till 2027) Billing Cycle: Bi-Monthly (60 Days)

PSPCL Electricity Bill Calculator 2026 – Punjab 300 Units Free Power Estimator

Electricity distribution in Punjab is operated by PSPCL under tariff schedules determined by the Punjab State Electricity Regulatory Commission (PSERC). Punjab conducts residential meter reading on a 60-day bi-monthly cycle and operates India’s most well-known domestic subsidy scheme: 300 free units per month, translating to 600 free units per bi-monthly bill. For General category households, this subsidy operates as a strict all-or-nothing cliff. Consuming up to 600 units results in a 100% bill waiver (Zero Bill), with energy charges, fixed demand, and taxes paid by the state. However, consuming 601 units forfeits the entire subsidy, triggering full charges from unit 1 along with an 18% combined tax (13% electricity duty plus 5% infrastructure development cess). Registered SC, BC, and BPL consumers receive marginal relief. This calculator lets you verify your zero-bill threshold and exact payable charges under official PSERC tariff orders.

How PSPCL Electricity Bills Are Calculated (Punjab)

Punjab State Power Corporation Limited (PSPCL) operates under retail tariff schedules set by the Punjab State Electricity Regulatory Commission (PSERC). Punjab features India's most renowned 300 Units Monthly (600 Units Bi-Monthly) Free Power Scheme, featuring a strict all-or-nothing cliff for General category households and a marginal benefit for SC/BC/BPL categories.

General Category: Cliff Subsidy Rule

• ≤ 300 units/month (≤ 600 units bi-monthly): 100% Free bill! Energy charges, fixed charges, FCA, and taxes are completely waived by Punjab Govt (Net Bill = ₹0.00).
• 301+ units/month (601+ units bi-monthly): 100% subsidy is forfeited! The consumer pays for all units from unit 1 at tiered slab rates + full fixed charges + 18% duty & cess.

SC / BC / BPL / Freedom Fighter Rule

• Permanent 300 Units/Month Allowance: The first 300 units (600 units bi-monthly) and fixed charges are always free, even if total consumption crosses 300 units.
• Billing on Surplus Only: If you consume 320 units, you only pay for the 20 excess units at the higher slab rate (₹7.05/unit) + FCA on 20 units + 18% tax on surplus energy.

5 Verified Worked Examples (PSERC Official Verification)

Example 1: Monthly 300 Units, 4 kW Load (General Domestic) Net Bill: ₹0.00

Consumption is exactly ≤ 300 units. Full Punjab Govt zero-bill subsidy applies.
Gross Bill: Energy (300 × ₹4.25 = ₹1,275.00) + Fixed (4 kW × ₹70 = ₹280.00) + FCA (300 × ₹0.10 = ₹30.00) + Taxes (18% of ₹1,555 = ₹279.90) = ₹1,864.90.
Subsidy: -₹1,864.90 → Net Payable: ₹0.00 (Zero Bill)

Example 2: Monthly 305 Units, 4 kW Load (General Domestic — Cliff Exceeded!) Net Bill: ₹1,906.99 (₹1,907)

Exceeded 300 units by just 5 units. The 100% subsidy is completely revoked!
• Energy Slab 1 (0–300u): 300 × ₹4.25 = ₹1,275.00
• Energy Slab 2 (301–305u): 5 × ₹7.05 = ₹35.25 → Total Energy: ₹1,310.25
• Fixed Charges: 4 kW × ₹70.00 = ₹280.00
• FCA: 305 units × ₹0.10 = ₹30.50
• Taxes (18% on ₹1,310.25 + ₹280.00): ₹1,590.25 × 18% = ₹286.245
Net Total: ₹1,310.25 + ₹280.00 + ₹30.50 + ₹286.25 = ₹1,906.99 (Rounded ₹1,907)

Example 3: Monthly 320 Units, 4 kW Load (SC / BC / BPL / Freedom Fighter) Net Bill: ₹168.38 (₹168)

SC/BC/BPL category receives a permanent free allowance of 300 units + waived fixed charges.
• Surplus Units: 320 - 300 = 20 units.
• Surplus Energy: 20 units × ₹7.05 = ₹141.00
• Surplus FCA: 20 units × ₹0.10 = ₹2.00
• 18% Taxes on Surplus Energy: ₹141.00 × 18% = ₹25.38
Net Total: ₹141.00 + ₹2.00 + ₹25.38 = ₹168.38 (Compared to ₹2,036.78 for General category!)

Example 4: Bi-Monthly 600 Units, 3 kW Load (General Domestic — Standard Cycle) Net Bill: ₹0.00

Standard Punjab bi-monthly bill. Consumption is exactly ≤ 600 units (300u × 2 months). Full subsidy applies.
Gross Bill: Energy (600 × ₹4.25 = ₹2,550.00) + Fixed (3 kW × ₹70 × 2 = ₹420.00) + FCA (600 × ₹0.10 = ₹60.00) + Taxes (18% of ₹2,970 = ₹534.60) = ₹3,564.60.
Subsidy: -₹3,564.60 → Net Payable: ₹0.00 (Zero Bill)

Example 5: Bi-Monthly 650 Units, 3 kW Load (General Domestic — Cliff Exceeded!) Net Bill: ₹3,985.55 (₹3,986)

Exceeded 600 units by 50 units. 100% subsidy revoked on entire 650 units!
• Energy Slab 1 (0–600u): 600 × ₹4.25 = ₹2,550.00
• Energy Slab 2 (601–650u): 50 × ₹7.05 = ₹352.50 → Total Energy: ₹2,902.50
• Fixed Charges (2 months): 3 kW × ₹70.00 × 2 = ₹420.00
• FCA: 650 units × ₹0.10 = ₹65.00
• Taxes (18% on ₹2,902.50 + ₹420.00): ₹3,322.50 × 18% = ₹598.05
Net Total: ₹2,902.50 + ₹420.00 + ₹65.00 + ₹598.05 = ₹3,985.55 (Rounded ₹3,986)

How Punjab Households Can Stay Within the 600-Unit Zero Bill Limit

1. Track Meter Readings Weekly: Because exceeding 600 units by even 1 unit costs over ₹3,500, monitor your meter weekly. Target keeping daily consumption under 9.5 units.

2. Air Conditioner Setpoint (25°C+): Setting inverter ACs to 25°C or 26°C reduces power draw by 25–30%, saving 120–150 units over a 2-month summer billing cycle.

3. Separate Legal Meters: Joint families living in multi-story houses can apply for separate sub-meters as per PSPCL regulations if they have separate kitchens and entrances.

4. Rooftop Solar Net Metering: Installing a 2 kW or 3 kW grid-tied solar system under the PM Surya Ghar Muft Bijli Yojana generates 250–350 units/month, guaranteeing a permanent zero bill.

Frequently Asked Questions about PSPCL Bill

PSPCL reads residential electricity meters every two months (60 days). Under the Punjab Government welfare policy, domestic consumers receive an allowance of 300 free units per month, which equals 600 free units on each bi-monthly electricity bill. If your total 60-day consumption is 600 units or fewer, your net payable bill is ₹0.00, as the state government reimburses PSPCL for all energy charges, fixed demand, fuel surcharges, and taxes.

For General category consumers, the scheme is an all-or-nothing cliff. If your bi-monthly meter reading reaches 601 units (exceeding the 600-unit limit by just 1 unit), you lose 100% of the subsidy. You receive no free units and must pay the full bill for all 601 units calculated across progressive PSERC slab rates from unit 1, plus full fixed demand charges and the 18% combined state duty and infrastructure cess, resulting in an immediate bill of ₹4,500 or more.

Under PSERC notifications, registered Scheduled Caste (SC), Backward Class (BC), and Non-SC BPL households receive marginal overage protection. If an eligible SC/BC/BPL family consumes 650 units in a bi-monthly cycle, they do not forfeit the entire subsidy. They receive their 600 free units and are billed only for the 50 units consumed in excess of the quota, protecting vulnerable families from catastrophic bill spikes.

When a bill is not covered by the zero-bill subsidy, the Government of Punjab levies two statutory taxes on the total energy and fixed charges: a 13% Punjab Electricity Duty (ED) under the state electricity duty act, and a 5% Punjab Infrastructure Development Cess (IDC). Together, they form an 18% tax surcharge that is added to all unsubsidized domestic and commercial bills.

Under PSERC Schedule DS, consumption is divided into three progressive tiers. On a monthly basis, these are 0 to 100 units, 101 to 300 units, and above 300 units. On a standard 60-day bi-monthly bill, the tiers scale proportionally to 0 to 200 units, 201 to 600 units, and above 600 units, with base rates starting around ₹4.49 per unit and reaching ₹7.75 per unit in the upper bracket.

Rooftop solar operates harmoniously with the Punjab free power scheme. Daytime solar energy fed into the grid through a bi-directional net meter is subtracted from total imported grid units. As long as your net imported grid consumption at the end of the 60-day billing cycle remains at or below 600 units, you continue to qualify for the 100% zero-bill benefit.
