What are Late Payment Surcharge Rules
The Late Payment Surcharge Rules 2022, notified by the Ministry of Power in June 2022, establish a statutory framework for enforcing payment discipline by DISCOMs to electricity generators. The rules apply escalating financial penalties on delayed PPA payments, providing legal mechanism for solar developers and other generators to recover delays.
Before LPS Rules 2022, DISCOM payment delays were chronic and largely unenforceable. Some financially stressed state DISCOMs delayed renewable PPA payments by 6-12 months, causing developer cash flow stress and impeding new investment. The Electricity (Late Payment Surcharge and Related Matters) Rules, 2022 set the surcharge as follows:
- First month of default: the base rate of LPS, defined as the State Bank of India one-year MCLR on 1 April of the financial year plus 5 percent
- Each further month of default: the rate rises by 0.5 percentage points
- Cap: never more than 3 percentage points above the base rate, and never above the LPS rate specified in the agreement
For Indian solar, LPS Rules 2022 are a key risk mitigant. Lenders and equity investors can factor LPS recovery into project economics. C&I buyers evaluating a RESCO PPA instead of direct DISCOM sale should still weigh payment discipline; see the Solar RESCO Model India Complete Guide for how PPA tariff and contract risk are assessed on the buyer side.
Why LPS matters
Payment certainty. Statutory backing for PPA payment terms, backed by the broader Electricity Act 2003 framework.
Lender comfort. Improves project bankability and equity IRR outcomes; the LCOE of Solar in India guide covers the DSCR and off-take security documentation lenders check alongside payment discipline.
Cash flow protection. Financial penalty on delayed payments.
DISCOM discipline. Incentivises timely payment.
Investment attractiveness. Reduces perceived sectoral risk.
LPS Rules 2022 structure

| Month 3 | Base rate + 1.0% |
| Month 4 | Base rate + 1.5% |
| Month 5 | Base rate + 2.0% |

Payment adjustment and rescheduling
Under the Rules:
- LPS is payable on the amount outstanding after the due date.
- Payments received are adjusted first towards LPS, then towards monthly charges, starting from the longest overdue bill.
- Outstanding dues up to the notification date, including LPS, can be rescheduled into equated monthly instalments: up to 12 instalments for dues up to ₹500 crore, rising to 48 for dues above ₹10,000 crore.
- Distribution licensees and other transmission users must maintain a payment security mechanism.
Real-world applications
PPA payment recovery.
Renewable developer cash flow protection.
Lender due diligence.
Sector-wide DISCOM reform.
LPS vs alternative mechanisms
| Mechanism | LPS | Letter of Credit | Payment Security Mechanism |
|---|---|---|---|
| Coverage | Dues covered by the Rules | Specific PPA | Specific PPA |
| Automatic | Payable on outstanding amounts | Pre-funded | Pre-funded |
| Cost | Base rate (SBI MCLR + 5%) stepping up monthly, within the cap | LC issuance fee | PSM management fee |
| Recovery time | Payments adjusted against LPS first | As per LC terms | As per terms |
Best practices
Document delivery and invoicing accurately.
File LPS claims promptly.
Track DISCOM payment patterns.
Escalate persistent delays to SERC/CERC.
Use combined with letter of credit for additional protection.
Indian market context

Key takeaways
Late Payment Surcharge Rules 2022 establish escalating penalties on DISCOM delays in solar PPA payments. Base rate (SBI one-year MCLR + 5 percent) in the first month, rising 0.5 percentage points a month to a cap of base rate + 3 percentage points. A risk mitigant for solar developers and lenders; check the PPA for any lower agreed LPS rate.
