RIICO Industrial Area Solar Rooftop: Lessee Guide 2026

Direct Answer

Most of Rajasthan's industrial capacity sits on RIICO land — 472 industrial areas across roughly 102,723 acres, with more than 42,344 units in production — so for most factories the practical path to rooftop solar runs through RIICO's lease and building-plan records rather than any dedicated solar permission. The state's economics are favourable: net metering up to 1 MW, a seven-year electricity duty exemption on captive renewable generation under RIPS 2024, and waived banking, wheeling and transmission charges for captive plants.

TL;DR

• RIICO's 2025 Building Regulations mandate solar water heating where industrial hot water is needed and reward green building, but do not separately regulate rooftop PV — practical clearance flows through your unit office and building-plan records.
• RIPS 2024 (notified 8 October 2024) grants a 100% electricity duty exemption for 7 years on captive renewable generation, including for MSMEs.
• The net metering cap is 1 MW (RERC, February 2024), and scheme approvals run through the Rajasthan Single Window Clearance system.

RIICO in brief: the landlord behind Rajasthan's industry

RIICO — the Rajasthan State Industrial Development and Investment Corporation, established in 1969 — is the state's sole industrial-land developer. Its portfolio spans 472 industrial areas on roughly 102,723 acres, with over 42,344 units in production. Beyond standard industrial estates, it has developed sector-specific parks: the Japanese Zone at Neemrana and Ghiloth, the EPIP at Sitapura, and two SEZs including the Mahindra World City joint venture. If your factory leases industrial land in Rajasthan, you are almost certainly a RIICO lessee — which makes its procedures the practical starting point for any rooftop solar plan.

What RIICO's rules actually say about rooftop solar

Two instruments govern a lessee's construction activity: the RIICO Disposal of Land Rules 1979 and the RIICO Building Regulations 2025, approved by the Institutional Development Committee (IDC) on 10 July 2025. The 2025 regulations push sustainability in specific directions — they mandate solar water heating where a unit needs industrial hot water, offer green-building incentives of ₹1–2 lakh, and require rainwater harvesting for plots of 500 sqm and above.

Rooftop PV, notably, is not separately regulated in these documents. There is no formal public RIICO rooftop-PV NOC policy. In practice, permission flows through your unit office and building-plan records: a solar installation is treated as part of the building's sanctioned plan rather than as a distinct approval. The checklist below reflects that practical reality.

Treat this as practical guidance for planning conversations with your unit office — not as a substitute for written confirmation from RIICO for your specific plot.

RIPS 2024: the incentive layer for captive solar

Rajasthan's investment promotion scheme, RIPS 2024, notified on 8 October 2024, strengthens the case materially. It provides a 100% electricity duty exemption for seven years on captive renewable generation — and it extends to MSMEs, not just large industry. Green-sector renewable energy units receive a 75% stamp-duty exemption along with a pollution board (PCB) fee waiver. Banking, wheeling and transmission charges are waived for captive plants, which matters for units considering capacities beyond their own net metering entitlement. Approvals under the scheme run through the Rajasthan Single Window Clearance system, consolidating the paperwork into a single channel.

Net metering and grid charges: where your plant sits

For most factory rooftops, the governing rule is the net metering cap of 1 MW — or sanctioned load/contract demand, whichever is lower — set by RERC's February 2024 amendment, with systems above that moving to net billing. The detailed framework, eligibility and documentation are covered in our Rajasthan net metering guide for industrial consumers. Plants exploring open access for larger capacities should model the applicable charges for the current financial year, which we break down in our Rajasthan open access charges guide for FY2026-27.

Sizing, area and structural checks

Sizing should start from your daytime load and contract demand headroom, then be checked against the roof. Rajasthan's strong irradiance supports high per-kW output, but usable area varies sharply between tin-shed and RCC roofs; the planning norms are set out in our guide to rooftop area required per kW and MW. Because RIICO plots often carry setback rules and shared infrastructure corridors, a structural and shadow assessment before sizing avoids costly redesigns later — and the statutory inspection requirements for industrial plants are covered in our CEIG approval guide.

Choosing an EPC partner in Rajasthan

A RIICO-lessee project adds two coordination points to a standard installation: aligning the building-plan record at the unit office, and timing the discom application around any construction activity. Partners with Rajasthan industrial experience — see our review of top solar companies in Rajasthan and our guide to the Rajasthan industrial solar installation landscape — will handle both alongside the discom and inspection workflow. Sun Wave Technologies serves Rajasthan across its RIICO industrial areas, from roof audit and structural assessment through discom approval and commissioning.

Frequently Asked Questions

Do I need RIICO's permission to install rooftop solar on my leased plot?

There is no separate public RIICO rooftop-PV NOC policy. In practice, clearance flows through your unit office and the building-plan record: intimate the unit office, confirm your lease terms, and keep the installation consistent with the sanctioned plan.

Does RIPS 2024 apply to my factory's solar plant?

RIPS 2024 extends a 100% electricity duty exemption for seven years to captive renewable generation, including for MSMEs. Confirm your unit's eligibility under the scheme through the Rajasthan Single Window Clearance process.

What happens above 1 MW in Rajasthan?

Systems above the 1 MW net metering cap move to net billing. Larger capacities can also be evaluated through open access, subject to the applicable banking, wheeling and cross-subsidy framework for the financial year.

Are there RIICO incentives for going green?

Yes. The 2025 Building Regulations offer green-building incentives of ₹1–2 lakh and mandate supporting measures such as rainwater harvesting for plots of 500 sqm or more, and solar water heating where industrial hot water is needed.

How much roof area does a solar plant need?

Area depends on roof type and module technology; our area-per-kW guide sets out planning norms for tin-shed and RCC roofs. A structural assessment should confirm usable area before capacity is finalised.

Who do I approach first — RIICO or the DISCOM?

Both, in the right order: settle the building-plan record and unit-office intimation first, then file the net metering application with your DISCOM. An experienced EPC partner can sequence both to avoid delays.
