- CEIG/CEI approval is an electrical safety sign-off — separate from net metering.
- It is usually needed for larger rooftop and HT systems, not small homes.
- The trigger is by kWp or voltage and is state-specific — verify.
- The inspector checks earthing, isolation, protection and the SLD against the install.
- Plan it into the timeline; missing it can stall energisation.
Many EPCs treat net metering as the only approval that matters, and then a larger job stalls at the last step. For bigger rooftop and HT systems, CEIG approval for solar net metering — the electrical inspector's safety sign-off — is a second, parallel clearance. It can be the difference between energising on schedule and waiting weeks. This guide shows when it applies and how to plan for it.
What CEIG / CEI approval is
CEIG or CEI approval is a sign-off from the Chief Electrical Inspector to Government (CEIG) or the state electrical inspector (CEI) confirming that an electrical installation is safe. For larger solar systems it is a distinct approval from net metering, and it often must be in place before the system can be energised. It exists to protect people and property from electrical risk.
The inspectorate works under the state's electrical safety rules, with the technical basis set by CEA standards. So while the DISCOM handles the connection and the meter, the inspectorate handles safety. On a big job, both must say yes.
CEIG vs CEI vs LEC
Names vary by state. Some call it the CEIG, some the electrical inspector or CEI. Some states also require a Licensed Electrical Contractor (LEC) of a certain class to sign the work. The terms differ, but the idea is the same: a qualified authority confirms the install is safe.
Why it is a separate sign-off
It is a separate sign-off because electrical safety and grid connection are two different concerns handled by two different authorities. The DISCOM cares about the connection, the meter and the grid. The electrical inspectorate cares about whether the installation itself is safe to run at its voltage and rating. A bigger, higher-voltage system carries more risk, so it gets the extra check.
Net metering and CEIG run in parallel
These approvals can run at the same time, not one after the other, if you plan it. The net-metering application goes to the DISCOM while the safety drawings go to the inspectorate. Running them in parallel keeps the timeline tight. See the net-metering timeline by state for how the steps stack up.
When CEIG / CEI approval is triggered
CEIG approval is usually triggered for larger rooftop systems and HT or higher-voltage connections, while small residential systems often do not need it. The exact trigger is set by each state — sometimes by capacity in kWp, sometimes by voltage — so verify the threshold for your state before you plan. Do not assume the same cut-off everywhere.
Thresholds are state-specific (by kWp or voltage) — verify.
CEIG bites hardest on industrial and HT projects. If you work that segment, read industrial and HT net metering for how the safety and connection steps combine.
What the electrical inspector checks
The inspector checks that the installation is electrically safe and matches the approved drawings. The review covers the system on paper and, for many jobs, on site. Passing it confirms the system meets the electrical safety rules before it is energised.
- Earthing — proper earthing of equipment and the system.
- Isolation and protection — isolators, breakers and protective devices.
- Cable sizing and routing — correctly rated for the load and safe.
- Inverter and equipment — compliant and correctly installed.
- Drawings vs reality — the SLD and layout match the actual install.
The single line diagram and the earthing and isolators are central to this review, so get them right before the inspector visits.
The approval process
The process follows a familiar shape across states, though the detail varies. Confirm the local steps with your state inspectorate.
The usual steps
- Submit drawings — the SLD and details to the electrical inspectorate, often signed by an LEC.
- Drawing approval — the inspectorate clears the design on paper.
- Installation — build to the approved drawings.
- Inspection — the inspector checks the site for safety.
- Safety / energisation approval — the sign-off that lets the system be energised.
Coordinate this with the DISCOM net-metering steps so the meter and the safety approval line up and the system can go live without a gap.
Timeline and fees
CEIG timelines and fees vary by state inspectorate and workload, so treat any figure as an estimate and confirm locally. A larger system with site inspection takes longer than a paper-only clearance. The fee is usually based on capacity or rating.
Build it into the schedule
Add the CEIG step to your project plan from day one for jobs above the state threshold. If you leave it to the end, a fully built system can sit idle waiting for the safety sign-off, which frustrates the customer and ties up your cash. Plan it in parallel with net metering.
Why EPCs trip on CEIG
CEIG problems are almost always planning problems, not technical ones. Avoid these and the approval is routine.
- Not knowing the threshold — assuming net metering is the only approval needed.
- Leaving it to the end — applying only after the build, so energisation waits.
- Wrong signatory — drawings not signed by the required LEC class.
- Drawings vs install mismatch — building differently from the approved SLD.
- Skipping it for a "small" big job — a system just over the threshold still needs it.
The fix is to flag the CEIG requirement at feasibility for any job near the threshold, and run it alongside the DISCOM steps.
Quote the CEIG cost and time to the customer
For jobs above the threshold, the inspector fee and the extra time are real parts of the project. Put them in the quote and the schedule from the start. A customer who is told up front that a larger system needs a safety sign-off, with its own fee and a few weeks, accepts it as normal. A customer who hears about it only when the system sits idle waiting for approval feels misled. Honest framing protects the relationship and your reputation.
Keep the LEC relationship warm
Many states need a Licensed Electrical Contractor of a set class to sign the drawings and the completion. If you run larger jobs regularly, build a steady relationship with an LEC of the right class rather than scrambling for one per project. A reliable signing engineer who knows your work turns the CEIG step into a routine hand-off instead of a bottleneck. Confirm the class the state requires for the system sizes you handle.
Coordinate the energisation window
The goal is for the safety sign-off and the DISCOM's meter installation to land close together, so the system can be energised in one window. If the CEIG approval comes through but the meter is not installed, or vice versa, the system waits. Track both steps against the same target date, and chase whichever is lagging. A coordinated energisation keeps the customer's savings starting on time and your cash flowing.
How SuryaHub helps you not forget the second sign-off
The CEIG step is forgotten because it lives outside the main net-metering flow, and SuryaHub brings it back into view. SuryaHub tracks every parallel approval on a job in government workflows, including the CEIG or electrical inspector step alongside net metering, and ties it to project execution so a larger system does not stall because one safety sign-off was missed. SuryaHub is pre-revenue; the real pilots are Suryantra Energy and RGESPL, and every figure here is a scheme or technical fact, not a guarantee.

Frequently asked questions
What is CEIG or CEI approval for solar?+
CEIG or CEI approval is a sign-off from the Chief Electrical Inspector to Government or the state electrical inspector confirming a solar installation is electrically safe. For larger rooftop and HT systems it is a separate approval from net metering, often needed before the system can be energised.
When is CEIG approval required for rooftop solar?+
CEIG approval is usually required for larger rooftop systems and HT or higher-voltage connections, while small residential systems often do not need it. The exact trigger is set by each state, sometimes by kWp and sometimes by voltage, so verify the threshold for your state before you plan.
What does the electrical inspector check?+
The electrical inspector checks that the installation is safe — earthing, isolation devices, protection, cable sizing, the inverter and the drawings against the actual install. The inspector reviews the SLD and may inspect the site. Passing this check confirms the system meets the electrical safety rules before energisation.
How long does CEIG approval take?+
CEIG approval timelines vary by state inspectorate and workload, and can run from a couple of weeks to longer for larger systems. Treat any timeline as an estimate and confirm the current processing time and fee with your state electrical inspectorate before you commit a schedule to the customer.
Is CEIG approval the same as net metering approval?+
No. CEIG approval is an electrical safety sign-off from the electrical inspectorate, while net metering approval is the DISCOM sanctioning the connection and meter. They are separate steps. For larger systems an EPC must plan for both, because missing the CEIG step can delay energisation.
How does SuryaHub help with CEIG and approvals?+
SuryaHub tracks every parallel approval on a job, including the CEIG or electrical inspector step alongside net metering, so a larger system does not stall because one sign-off was forgotten. SuryaHub is pre-revenue; the real pilots are Suryantra Energy and RGESPL.
