Rajasthan's New BESS Mandate for C&I Solar Above 5 MW

Direct Answer: Does Rajasthan Now Require BESS With My Solar Project?

For most rooftop-scale C&I solar in Rajasthan, no — this doesn't apply to you yet. But if you're developing (or planning) a solar, wind or hybrid renewable project above 5 MW on the State Transmission Utility (STU) network — captive, group captive, third-party sale or green energy open access — Rajasthan has proposed a mandatory Battery Energy Storage System (BESS) requirement, with a draft Standard Operating Procedure (SOP) released by the Rajasthan Renewable Energy Corporation Limited (RRECL) in August 2026.

Under the draft: new STU-connected renewable projects above 5 MW must install BESS with a minimum 2-hour storage duration, sized at at least 5% of the renewable capacity. A separate rule applies to captive plants sized between 100–200% of a consumer's contract demand, requiring BESS to store at least 20% of the energy generated by capacity beyond the 100% mark. This is a compliance and metering obligation, not a tariff change — but the penalties for non-compliance are serious enough that any large open-access or captive buyer in Rajasthan should understand it now, before signing an EPC contract.

Regulatory status last checked: 24 August 2026 — this is a draft SOP, not yet finalised.

Where This Rule Comes From

The draft SOP implements the Rajasthan Integrated Clean Energy Policy, 2024, which calls for BESS alongside renewable projects to strengthen grid stability, enable more dispatchable renewable power, and support the state's Renewable Consumption Obligation and Energy Storage Obligation targets. RRECL was designated the nodal agency for monitoring and verification following a decision at the 37th Meeting of the Coordination Committee of Rajasthan State Power Sector Companies on 5 December 2025.

Who Does the Draft SOP Cover?

The framework applies to commercial and industrial consumers developing solar, wind or hybrid renewable generating facilities on the STU or discom network under any of these structures:

Captive
Group captive
Third-party sale
Green Energy Open Access

The Two BESS Thresholds

Project type	Threshold	BESS requirement
New renewable project on STU network (excluding hydro)	Capacity above 5 MW	Minimum 2-hour storage duration; BESS capacity ≥5% of installed renewable capacity
Renewable-based captive power plant	Capacity 100–200% of consumer's contract demand	BESS must store ≥20% of the energy generated by the capacity beyond 100% of contract demand

Compliance is assessed on an energy basis (in MWh), not just installed power rating, and BESS becomes an integral part of the project wherever mandated under applicable Rajasthan Electricity Regulatory Commission (RERC) regulations.

Metering, Reporting and the Compliance Portal

A few operational details matter for anyone actually building a project under this framework:

Separate metering is required for renewable generation and for BESS charging/discharging — a single combined meter is explicitly not accepted.
Monthly meter readings are the primary basis for compliance verification and penalty calculation.
Declared stored energy at commissioning must be maintained throughout the project's lifecycle; if available BESS energy falls below the declared level, the developer must restore the deficit within a timeline prescribed by RRECL.
Annual BESS performance reports are due to RRECL by 31 May of the following financial year.
RRECL plans a dedicated BESS monitoring and compliance portal; until it's operational, submissions go by email.
Any change in installed renewable capacity or contract demand must be reported to RRECL within 10 days, with the BESS obligation adjusted accordingly.
Removing, relocating or decommissioning mandated BESS requires prior written RRECL approval — unauthorised removal is treated as a serious (Category A) non-compliance.

What Happens If You Don't Comply?

The draft SOP sets out two non-compliance categories:

Category A — non-installation, unauthorised removal, or prolonged unavailability (more than 30 consecutive days, or more than 45 days total in a quarter). Consequences include denial of commissioning certificates, suspension of open access/banking/wheeling/captive-status approvals, withdrawal of already-adjusted wheeled energy, and — if non-compliance continues beyond 90 days — potential cancellation of the project's registration and a recommendation to withdraw grid connectivity.
Category B — a proportionate shortfall, where the actually commissioned renewable capacity is lower than approved. Wheeled energy is adjusted only in proportion to installed BESS capacity; failing to complete the proportionate BESS installation within six months escalates the case to Category A.

Performance metrics like round-trip efficiency, state of health, availability and the renewable-charging share are governed by the project's power purchase agreement — RRECL is not proposing a separate performance-penalty layer on top of PPA terms.

What This Means for a C&I Buyer Right Now

If your project is rooftop-scale and under 5 MW, this draft SOP doesn't apply. Continue planning against the existing Rajasthan net metering framework for your rooftop solar.
If you're planning a large captive, group captive or open-access project above 5 MW on the STU network, build BESS capex and O&M into your financial model now, rather than treating it as a possible future add-on — the direction of this policy is clear even before final notification.
If you already operate a captive plant sized 100–200% of your contract demand, check whether the incremental-capacity BESS threshold applies to you, since this category catches plants that were sized generously for future load growth.
Ask your EPC or open-access aggregator whether their proposed project design already anticipates this SOP — retrofitting BESS and separate metering after commissioning is more expensive than designing for it upfront.

Frequently Asked Questions

Is the RRECL BESS SOP final and legally binding yet?

As reported, this is a draft SOP as of August 2026, implementing the Rajasthan Integrated Clean Energy Policy, 2024. Confirm the current status with RRECL or your EPC before assuming it's fully in force, but plan on the assumption that the core 5 MW / 2-hour / 5% framework will be finalised in substantially this form.

Does this apply to rooftop solar under net metering?

The draft SOP targets STU-connected projects above 5 MW and captive plants sized 100–200% of contract demand — not standard rooftop net-metered systems, which in Rajasthan are typically capped around 1 MW. See our Rajasthan net metering guide for the rules that actually govern most C&I rooftop projects.

What size of BESS do I need for a 20 MW open-access solar project?

Under the draft rule, a minimum 2-hour storage duration sized at 5% of the 20 MW renewable capacity — i.e., at least 1 MW / 2 MWh, subject to final RRECL guidance and your specific project structure.

Can I remove my BESS once compliance is verified?

No — removal, relocation or decommissioning of mandated BESS requires prior written approval from RRECL. Unauthorised removal is treated as a serious non-compliance that can lead to denial of approvals or project registration cancellation.

What if my actual commissioned capacity is lower than what was approved?

That's a Category B case — your wheeled energy is adjusted proportionately to your installed BESS capacity, and you have six months to complete the shortfall before it escalates to the more serious Category A treatment.
