CEIG Approval in Maharashtra: Electrical Inspector Process for Factories and Solar

In Maharashtra the Electrical Inspector approves the installation plan and, after you build and test, grants permission to charge it, both through the Mahaonline portal. The Inspectorate's notice allows 30 days per stage, counted only for applications without defects. The officer depends on voltage: Electrical Inspector up to 33 kV, a Superintending Engineer to 220 kV, the Chief Electrical Inspector beyond.

When does an installation in Maharashtra need the Electrical Inspector?

The legal basis is the Electricity Act 2003 and the CEA (Measures relating to Safety and Electric Supply) Regulations, 2023. Under regulation 45, an installation above the voltage the state has notified is inspected by the Electrical Inspector before supply starts, or before it restarts after six months or more of shutdown; at or below that voltage the owner inspects, tests and self-certifies and sends the report to the Inspectorate. The Inspectorate's own service notice describes the inspected route as an online application with fees on the Mahaonline portal, with test reports from a licensed electrical contractor, and says permission is granted if the installation is found satisfactory under regulation 45.

That means HT consumers, substations, transformers, DG sets and generating units, including solar, are the usual inspected cases, but the threshold is the state's to set. We read the notice's lowest inspected band as above 650 V. Confirm the notified voltage and the capacity above which a generating unit needs inspection with the Inspectorate before you plan, because both change what you file.

Who approves, and how long does it take?

The Inspectorate's notice names the designated officer by voltage band and gives one time limit. The state's Right to Public Services portal, Aaple Sarkar, lists the matching services under the Energy Department.

Read the 30 days with care. The notice's note says plan approval and permission for charging are each 30 days, separately, and that the period is considered only for applications in which the office observes no defect. A file that is queried takes longer than the notice suggests, so build the programme on a clean file and a margin for remarks. Aaple Sarkar lists "Application for plan approval of electrical installation", "Permission for charging of electrical installation", and generating-set services: plan approval, energization and registration. The Inspectorate's duties note still cites the 2010 regulations in places, so use it for the sequence, not for thresholds.

What is the sequence?

1. Plan approval. The owner, consumer or supplier applies online with fees. The Inspector approves the plan or returns remarks; on resubmission after compliance it is approved.
2. Construction to the approved plan. Changes during construction should be taken back to the Inspector, not discovered at inspection.
3. Test reports. A licensed electrical contractor tests and certifies the installation.
4. Application for charging. A second online application with fees, and the documents and reports.
5. Site inspection and permission. If the installation is satisfactory under regulation 45, permission to charge issues, and the supplier energises.

Generating units, including solar plants that fall in the inspected band, follow the same plan-then-energisation pattern under the generating-set services.

Put both stages in the project programme. Because the test certificate cites the number and date of the approved plan, the plan application should go in before site electrical work starts, not after the shed is roofed. The charging application then needs a licensed electrical contractor's reports, so the contractor's licence is a precondition for the site work, not a paperwork item at the end. Allow for the Inspector's visit date, any defect list and the supplier's own energisation step after permission.

What should the file contain?

The Maharashtra notice refers to "necessary documents" and test reports without listing drawings, so ask the office for its current checklist. Across states the set is consistent, and it is what an inspector can read quickly:

• A single-line diagram showing existing and proposed work, with protection and metering.
• Equipment layout and plot plan, with key plan.
• Earthing layout showing electrodes, with calculations where the voltage warrants them.
• For generation, the plant details, the protection and synchronising arrangement, and the DISCOM's feasibility or sanction.
• After construction: insulation resistance, earth resistance of each electrode, and the contractor's and supervisor's signed certificates.

Most queries come from drawings that do not match the built installation or from missing earth values. Our Electrical Inspector approval guide sets out the drawing-first sequence, and the CEIG readiness calculator lets you check where your file stands.

How does this connect to solar and net metering in Maharashtra?

A factory solar plant needs the DISCOM's feasibility and net-metering approval as well as the Inspector's clearance where it falls in the inspected band. The state regulator's rooftop regulations govern the net-metering arrangement. MERC's 2023 explanatory memorandum records that its existing rooftop regulations limit net-metered capacity to 1 MW or the contract demand or sanctioned load, whichever is lower, and that the Commission proposed to keep 1 MW rather than adopt the central default of 500 kW. Check the current regulation, because a draft is not the final text. Our sanctioned load calculator checks your headroom, and the industrial solar EPC page explains how the plant is designed and approved.

What goes wrong most often?

• Plan and site diverge. The installation is built differently from the approved plan, and the test certificate refers to the wrong approval.
• Test values missing. Earth resistance is given for the system but not per electrode.
• Permission treated as a formality. The DISCOM will not energise an HT connection without it, so a finished plant waits with idle staff and machines.
• Self-certification assumed. The owner assumes the installation is at or below the notified voltage without checking it, or without checking the exceptions in the regulations.
• Duties forgotten. Approval is a gate, not a discharge; the owner's continuing duties include the Electrical Safety Officer for factories above 250 kW connected load.

How Secured Engineers helps

• Electrical design is done in-house, so the single-line diagram, layouts and earthing drawings come from one set.
• Fire NOC, CEIG and DISCOM net-metering filings are prepared in-house.
• MEPF and solar can sit under one contract.
• We work from offices in Noida (Delhi NCR) and Ludhiana, with 535+ projects across 18+ states and 89.77% repeat clients.
• This is a buyer's guide. Our site does not describe delivered work in Maharashtra, and a Maharashtra file would be prepared by our approvals team, mobilising from Noida and Ludhiana. We do not sell audits; we review files and rectify drawings.
