State rules and DISCOM procedures: application to commissioning

A system that is installed but not connected earns nothing, and the customer blames the installer, not the DISCOM. A large share of an installer's time goes into paperwork, follow-ups and DISCOM visits. Doing this well, and setting expectations honestly, is as important as good wiring. This lesson explains the framework and the practical steps.

The layers of rules

Think of it as a stack. Each layer must follow the ones above it.

1. Electricity Act, 2003: the parent law.
2. Central Rules: especially the Electricity (Rights of Consumers) Rules, 2020, as amended in 2021–2024, which give consumers the right to become "prosumers", set the net-metering framework and set timelines for DISCOMs.
3. CEA regulations: technical rules for connectivity of distributed generation (2013, amended), safety and electric supply (2023), and metering.
4. SERC regulations: each state commission's rooftop / grid-interactive / net-metering regulations: capacity limits, settlement, surplus rate, charges.
5. DISCOM procedures and circulars: forms, fees, portals, meter specifications, inspection practice.
6. Scheme guidelines: PM Surya Ghar and any state top-up schemes.

When a DISCOM office tells you something that seems wrong, find which layer it comes from. A local practice cannot override the SERC regulation, and an SERC regulation must follow the central Rules.

A typical application, step by step

Steps vary by state and DISCOM, and many are now done through the PM Surya Ghar portal for residential customers. The usual sequence:

1. Check the connection: category (residential, commercial), sanctioned load, single or three phase, and any arrears. Arrears usually block the application.
2. Apply on the DISCOM or national portal with the documents below and pay any fees.
3. Technical feasibility: the DISCOM checks the distribution transformer capacity and the sanctioned load. Under the 2024 amendment to the Rights of Consumers Rules, systems up to 10 kW are treated as feasible, and larger ones must be decided within set timelines (check the current notification).
4. Load enhancement if the proposed system exceeds the sanctioned load (where the SERC caps the system at sanctioned load).
5. Agreement: a net-metering (or connection) agreement between consumer and DISCOM.
6. Installation by a registered or licensed vendor.
7. Work completion report with test results, earthing values, single-line diagram and equipment details.
8. Inspection: by the DISCOM; for larger systems, by the state Electrical Inspectorate or through a self-certification route. Thresholds differ by state.
9. Meter testing and installation: the net meter (and generation meter if required) is tested in the DISCOM lab or supplied by the DISCOM, then installed and sealed.
10. Synchronisation and commissioning: the DISCOM records the date, and billing changes from the next cycle.

Documents to collect

Prepare a folder for every customer before you apply:

• Latest electricity bill, with no arrears, in the applicant's name
• Proof of ownership (sale deed, property tax receipt) or owner's consent where allowed
• Identity proof (Aadhaar) and photographs
• Society or RWA no-objection for apartments, where the roof is common property
• Proposed layout and single-line diagram
• Datasheets and test certificates (BIS/IEC) for modules and inverter; DCR certificate where required
• Vendor registration, electrical contractor licence and supervisor details
• After installation: work completion report, test results, earth resistance values, photos, serial numbers

How states differ: examples to check

From our state notes (October 2026; verify each before quoting):

The point is not to memorise this table. It is to know which questions to ask for any state: settlement period, surplus rate, capacity limit, extra charges, metering arrangement and inspection threshold.

Tracking and escalation

• Keep an application register: customer, application ID, date of each step, DISCOM officer contacted, next action. A shared spreadsheet is enough to start.
• Visit with complete papers. Most "pending" files are pending because something is missing. Ask the officer what is missing and get it in writing (an email or a portal remark).
• Use the published timelines. The Rights of Consumers Rules and SERC standards of performance set time limits for DISCOM actions. Polite reference to them often moves files.
• Formal grievance: if a DISCOM fails to act, the customer (not the vendor) can approach the DISCOM's grievance cell, then the Consumer Grievance Redressal Forum (CGRF), and then the Electricity Ombudsman. Help the customer draft the complaint; it is their right.

Key points

• Rooftop connection rules stack: Act → central Rules → CEA regulations → SERC regulations → DISCOM procedures → scheme guidelines.
• A typical process runs: check connection, apply, feasibility, agreement, install, completion report, inspection, meter, commissioning.
• Prepare a complete document folder before applying; most delays are missing papers.
• States differ on settlement, surplus rate, limits, extra charges and inspection thresholds; know the questions to ask.
• Track every application, use published timelines, and escalate through grievance channels, never through bribes.
