Official 2026 Consumer Rights & DISCOM Escalation Protocol in Kerala
Under the latest regulations notified by the Kerala Electricity Regulatory Commission (KSERC) and MNRE guidelines, consumers across Kochi, Thiruvananthapuram, Kozhikode, Thrissur, Kollam and Kannur are legally protected by strict Service Level Agreements (SLAs). If your rooftop solar net meter installation, feasibility inspection, or subsidy disbursement is delayed, follow this formal escalation hierarchy:
Submit written grievance ticket regarding net meter testing or portal document hold.
Level 2: Circle Superintending Engineer
Executive Engineer (Solar Renewable Cell)
7 Working Days
Formal grievance filing on DISCOM portal with application acknowledgement number.
Level 3: Regulatory Ombudsman
Consumer Grievance Redressal Forum (CGRF) under Kerala Electricity Regulatory Commission (KSERC)
15 Working Days
Binding legal hearing. Utility can be fined daily penalties for willful commissioning delays.
Mandatory Inspection Documents Checklist
When the DISCOM inspection team visits your premises for the final bi-directional meter synchronization, have these exact physical documents signed and organized in a physical file:
Joint Inspection Report (JIR): Signed by the homeowner and the empanelled solar engineer.
Factory Flash Test Report: Showing peak watt test results matching your panel serial numbers.
DCR Undertaking Stamp Paper: Affirming domestic solar cell content as mandated by MNRE.
Inverter Type Test Certificate: Confirming anti-islanding compliance (IS 16221 / IS 16169).
💡 Consumer Tip: Always keep a timestamped digital copy of your Work Completion Report (WCR) and joint inspection form. If your net meter is not installed within 15 days of successful plant inspection, your vendor can register a formal complaint on the PM Surya Ghar National Grievance Portal.

6. Proactive Escalation Tips for Stalled Applications
If your application gets delayed at the DISCOM sub-division office for more than 15 days, call the national portal helpline (15555) with your application ID. You can also visit your local DISCOM junior engineer (JE) office with your technical feasibility letter to fast-track net meter dispatch.
7. Tracking Digital Status Updates & DISCOM SMS Alerts in Kerala
Throughout your application cycle in Kerala, the national portal and your local power utility (KSEB, KSEB) send automated SMS and email notifications at each milestone. Homeowners can track real-time progress using their registered mobile number:
Status: 'Feasibility Approved': The DISCOM field office has verified that your neighborhood distribution transformer has sufficient capacity. Your vendor can now begin rooftop installation.
Status: 'Work Completion Submitted': Your vendor has uploaded photos of the panels, inverters, and three chemical earth pits. A DISCOM junior engineer (JE) is automatically assigned for site inspection.
Status: 'Net Meter Installed & Synchronized': The bi-directional meter is active and your official Commissioning Certificate is generated on the portal. Subsidy DBT disbursement triggers automatically.
If any status remains static for more than 10 working days, visit your local DISCOM sub-division office or raise a ticket on the national solar portal (pmsuryaghar.gov.in) referencing your application ID.
8. Expediting Net Meter Dispatch & Avoiding Store Delays in Kerala
If physical panel installation is complete but your bi-directional meter has not been dispatched from the utility testing lab after 15 days, take proactive action:
Request your empanelled vendor to provide the official DISCOM Work Completion Report (WCR) submission acknowledgment receipt number.
Visit the local sub-divisional Assistant Engineer (AE Metering) with your application printout to confirm meter allocation from the central zonal store.
Under Kerala regulatory standards, DISCOMs face statutory service compensation penalties if net meter energization exceeds 30 calendar days from WCR submission.
