Solar EPC Company for Factories in Goa: Electricity Department Rules, Approvals and Cost

A factory in Goa can net-meter solar up to 500 kWp at one premise, never above its sanctioned load or contract demand, under the JERC regulations for Goa and the Union Territories as amended in 2024. Larger projects fall under net billing, where exports earn the Commission's feed-in tariff. Our turnkey benchmark is ₹24,000–32,000 per kW excluding GST.

Which metering route can a Goa factory use?

Goa's electricity is supplied by the state Electricity Department and regulated by the Joint Electricity Regulatory Commission (JERC) for Goa and the Union Territories. The base text is the JERC Solar PV Grid Interactive System based on Net Metering Regulations, 2019, changed by a first amendment in 2024 that added gross metering and net billing. The department's own website still lists an older 2018 net metering document and a 2017 solar policy, so work from the Commission's text, not from old downloads. Press reports in 2025 described further changes; we could not retrieve a notified text for them, so ask the department whether anything has been amended since 2024.

The practical lesson is to size the plant to your own load. Net metering rewards consumption on site at the retail tariff, while exports above the net-metering ceiling are valued at the feed-in tariff, so a plant much larger than daytime demand loses its economic edge. Our guide to open access solar covers the alternative for larger loads. The regulations also cap solar on a distribution transformer at 75 percent of its capacity unless the licensee's load study allows more, which makes the transformer the first thing to check.

A worked case shows the edge. Take a factory with an 800 kVA contract demand and roof for 700 kWp. The demand does not stop the plant, but 700 kWp is above the 500 kWp net metering ceiling, and the amendment places a project higher than 500 kWp under net billing or net feed-in. The choice is then between staying at or below 500 kWp to keep retail-rate offset, or accepting feed-in valuation on exports. Ask the department in writing how it treats two plants at one premise before you rely on a split, because the text does not answer that.

What does the approval path look like?

1. Apply to the Electricity Department for connectivity with the one-time registration fee, which the 2019 text puts at ₹500 unless the Commission has since changed it. Applications are to be handled through a web-based system.
2. Technical feasibility: for rooftop solar the study must be completed and communicated within fifteen days, otherwise feasibility is presumed. Rooftop applications up to 10 kW, complete in all respects, are deemed accepted without a study.
3. Build the plant to the inverter, harmonics and protection standards in the regulations' annexure, with the metering the department specifies. Our note on solar inverters shows what we check for.
4. Inspection and connection: the department tests and connects. Plants above 500 kWp are to be checked by the Chief Electrical Inspector associated with the licensee. The department's website lists an Electrical Inspectorate section with procedures and forms, including NOC for commissioning of HT units, so confirm the forms for your voltage level.
5. Sign the connection agreement and start net metering. Solar projects installed under the regulations are exempt from banking charges.

What does the cost band mean at 100 kW, 500 kW and 1 MW?

Our published band for turnkey commercial and industrial rooftop solar is ₹24,000–32,000 per kW excluding GST, covering modules, inverters, structure, cabling, earthing, protection, installation, commissioning and the DISCOM paperwork. On our size pages that works out at about ₹28–32 lakh for 100 kW, about ₹1.30 crore for 500 kW, and ₹2.40–2.60 crore for 1 MW, all before GST. Goa adds three cost items to read in a quote: structure and fixing designed for coastal air and monsoon wind, any HT interface work, and, above 500 kWp, the metering and agreement structure for net billing. Run your own load and tariff through the solar calculator before you compare bids.

Where do Goa's factory roofs sit?

The Goa government's industrial development corporation lists 22 industrial estates in its directory. The names we could read include Verna, Corlim, Cuncolim, Madkaim, Kundaim, Pilerne, Mapusa, Margao, Sancoale, Tivim, Tuem, Bethora, Shiroda, Panchwadi, Bicholim, Honda, Pissurlem, Latambarcem, Colvale, Canacona and Kakoda. Many plots in such estates are leased rather than freehold, so check the lease terms on roof modifications and the landlord's consent before design starts. The directory we used is from 2020 and may have changed.

What should you confirm with the Electricity Department?

• The latest notified regulation text and amendment, not a news summary.
• Your sanctioned load or contract demand, since it caps plant size.
• Transformer headroom against the 75 percent rule.
• Whether your tariff category is on time-of-day billing, which affects the meter and the settlement.
• The inspector's requirements for your voltage level, and any fees.
• Whether the plant will be self-owned or third-party owned, because ownership decides who services it and who claims the tax depreciation.
• Monsoon generation in your estate, which the calculator estimates from location but a site study confirms.

How Secured Engineers helps

We are a pan-India EPC contractor. Design is done in-house, and Fire NOC, CEIG and DISCOM net-metering filings are prepared in-house, with MEPF and solar available under one contract. We work from offices in Noida (Delhi NCR) and Ludhiana, across 535+ projects in 18+ states, with 89.77% repeat clients. Goa is not among our published project locations, so a Goa job would be a mobilisation from those offices, with the site-team arrangement agreed in writing before award.
