Punjab’s rooftop solar market has a distinctive context that no other state shares: the interaction of PM Surya Ghar’s net metering benefit with the AAP government’s 300 free electricity units scheme. For residential consumers in Punjab, rooftop solar can combine with the state’s free units policy to drive electricity costs to near zero. Understanding this double benefit — and explaining it clearly in proposals — is a commercial differentiator for installers working in Punjab.
PSERC Net Metering Regulations
PSERC issues net metering regulations that PSPCL implements as the sole DISCOM. Punjab’s single-DISCOM structure simplifies compliance significantly:
- One application portal
- One set of documentation requirements
- Consistent processing standards across the state
Key provisions:
- Residential: Net metering up to sanctioned load (most residential connections: 1–5 kW sanctioned load)
- Commercial and industrial: Up to 1 MW under standard net metering
- Export rate: PSPCL’s APPC — approximately Rs. 3.40–3.90/unit, set annually by PSERC
- Settlement: Monthly
PSPCL: The Sole DISCOM
PSPCL (Punjab State Power Corporation Limited) handles generation, distribution, and retail supply across Punjab. Unlike states with multiple DISCOMs, every rooftop solar application in Punjab — from Gurdaspur in the north to Fazilka in the south — goes through PSPCL.
Application process: PSPCL has an online consumer portal for solar net metering applications. Submit:
- Consumer account number
- Load sanction letter
- Site plan with rooftop layout
- Single-line electrical diagram
- Module and inverter BIS certificates (IS 14086, IS 16221)
- ALMM compliance declaration (for PM Surya Ghar)
- Proof of ownership
Processing timeline: Typically 20–40 days for technical sanction in urban Punjab (Chandigarh, Ludhiana, Amritsar, Jalandhar). Rural district processing can take 30–60 days.
Net meter installation: 30–60 days from commissioning inspection. Follow up with PSPCL’s metering department directly after inspection to avoid delays.
The AAP Free Electricity Scheme and Rooftop Solar
The AAP government in Punjab introduced a scheme providing 300 units of free electricity per month to domestic consumers. This creates a unique financial interaction with rooftop solar net metering:
Without solar: A household consuming 300 units/month pays zero for those 300 units under the free scheme. Additional consumption is billed at standard tariff.
With solar + net metering: The household’s solar system generates, say, 350 units/month. 300 units of the household’s consumption are offset by solar generation; surplus 50 units are exported at APPC. The free 300 units scheme still applies to any consumption not covered by solar self-consumption.
The practical outcome: For a Punjab household consuming up to 300 units/month with both the AAP free scheme and a net-metered solar system, the electricity bill can effectively reach zero — with the solar’s net metering credits providing additional income or future credit buffer.
Billing Mechanism: Confirm with PSPCL
The specific billing mechanism when both the AAP free scheme and net metering apply simultaneously can vary by consumer account type and PSPCL’s current billing system configuration. Before quoting zero-bill outcomes to residential customers in Punjab, confirm the billing interaction with the relevant PSPCL sub-division. Mechanisms are updated as PSPCL’s billing software evolves.
PEDA: State Renewable Energy Agency
PEDA (Punjab Energy Development Agency) is the state nodal agency for renewable energy:
- PM Surya Ghar coordination: Manages vendor empanelment for PM Surya Ghar in Punjab; coordinates with PSPCL on implementation
- PM-KUSUM: Coordinates Component A (farmer solar plants) and Component C (agricultural pump solarisation) across Punjab
- State solar schemes: Administers state-level incentives and awareness programmes
- RPO monitoring: Tracks Punjab’s renewable energy compliance
For PM Surya Ghar work, PEDA registration alongside PSPCL empanelment is the standard requirement for installers in Punjab.
Punjab Solar Policy
Punjab’s solar policy framework covers:
- Rooftop solar targets for residential, commercial, and institutional buildings
- Agri-solar under PM-KUSUM (critical for Punjab’s agricultural economy)
- RESCO model facilitation for commercial-industrial consumers
- RPO targets for PSPCL
Punjab’s government buildings and institutional sector (schools, government hospitals) represent a significant rooftop solar market under state solar policy.
PM-KUSUM in Punjab: Agricultural Solar Opportunity
PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthan Mahabhiyan) is particularly significant in Punjab:
Component A (Decentralised Ground-Mounted Solar):
- Farmers install solar power plants (0.5–2 MW) on agricultural land
- Power sold to PSPCL under a 25-year PPA at PSERC-approved tariff
- Provides farmers with regular income from otherwise unproductive or marginal land
Component B (Solarisation of Grid-Connected Agricultural Pumps):
- Individual agricultural pump sets (< 7.5 HP) are solarised
- Surplus solar generation (when pump is not running) is exported to the grid
- Farmer benefits: reduced diesel dependence, net metering income
Component C (Solarisation of Grid-Connected Agricultural Pumps — Feeder Separation):
- Applicable where agricultural feeders are separated from domestic feeders
- Larger-scale pump solarisation with feeder-level solar installation
- PSPCL buys surplus solar at APPC
Punjab’s agricultural electricity load is enormous — the state provides heavily subsidised (often free) power to farmers for irrigation. PM-KUSUM addresses this by converting the subsidy burden into a solar opportunity. For installers, agricultural solar under PM-KUSUM is a distinct market from residential/commercial rooftop solar, with its own PEDA and PSPCL application channels.
Pro Tip: Market the Double Benefit in Punjab
Punjab is the only state where a residential consumer can combine the AAP government’s 300 free units scheme with PM Surya Ghar’s net metering benefit. Use solar proposals software to clearly show: current bill (post free-units), bill after solar, and the net metering credit — this combined story converts better than standard payback period calculations used in other states.

Frequently Asked Questions
Is PSPCL the only DISCOM in Punjab?
Yes. PSPCL is Punjab’s sole electricity distribution company. All rooftop solar applications in the state go through PSPCL.
How does the AAP free electricity scheme interact with solar?
Both the AAP 300 free units scheme and PM Surya Ghar net metering can apply simultaneously, potentially reducing bills to zero or near-zero for households consuming up to 300 units/month. Confirm the specific billing mechanism with your PSPCL sub-division.
What is the export rate?
Approximately Rs. 3.40–3.90 per unit (PSPCL APPC, set annually by PSERC, monthly settlement).
What is PM-KUSUM?
A central government scheme for agricultural solar — converting farm land into solar generation assets (Component A), solarising agricultural pumps (Component B and C). PEDA coordinates PM-KUSUM in Punjab. A major opportunity for installers beyond the standard residential rooftop segment.
