					</table>India’s first virtual net metering (VNM) rooftop solar project under the PM Surya Ghar program has been implemented at a residential apartment in Raipur, Chhattisgarh. The project has delivered meaningful electricity savings for 20 households since it was commissioned four months ago.
The 60 kW rooftop solar system installed at Parthivi Pacific Apartments is expected to deliver annual savings of ₹630,000 (~$6,980), translating to savings of about ₹31,500 (~$349) per household on electricity bills.
Virtual net metering allows electricity generated from a single shared rooftop solar system to be used by multiple households. The power produced is fed into the grid and virtually divided among participating consumers based on their agreed share. Each household receives energy credits that are adjusted against its electricity bill, helping reduce overall grid power consumption and costs.
For residential prosumers who can avail of central financial assistance under the PM Surya Ghar: Muft Bijli Yojana, the VNM comes as a bonus.
The VNM Project
<a href="https://jaivikrenewables.com/" target="_blank" rel="noopener">Jaivik Renewables</a> installed the rooftop solar system in March 2025, but it was commissioned in September 2025.
The project was selected in joint collaboration with the residents, the installer, and DISCOM.
GP Singh, Executive Member of the Parthivi Pacific Residents’ Welfare Association, said, “During my time at the Chhattisgarh State Load Despatch Center, my interactions with developers gave me the idea to set up a rooftop solar project under the VNM model at my apartment.”
As a pilot project, the 60 kW solar system was installed at a total cost of ₹2.4 million (~$26,597). Under the PM Surya Ghar Program, each beneficiary received a subsidy of ₹75,300 (~$835). In total, the project received ₹1.5 million (~$16,621) in subsidies.
Chandra Sekhar Reddy, Managing Director at Jaivik Renewables, said that with the subsidy support, the estimated payback period is ~1.5 years.
The project generates around 250–260 units (kWh) per day, translating to roughly 7,500–8,000 units per month.
The rooftop solar system uses <a href="https://www.adanisolar.com/" target="_blank" rel="noopener">Adani Solar</a>’s 570 Wp TOPCon bifacial modules paired with <a href="https://www.luminousindia.com/?srsltid=AfmBOoqRt4gu_ZYbeWLAHlOdCBWpD0vraxyS0xpBuEAJE_fWjOke0Kva" target="_blank" rel="noopener">Luminous&#8217;</a> 60 kW inverters.
Through the rooftop solar system, households can meet up to 100% of their electricity requirements, although coverage may be lower for prosumers with higher consumption. Under the VNM model, each household receives a 5% share of the system’s total generation. The installation is mounted on an elevated structure, allowing residents to continue using the rooftop area beneath the array of panels for other purposes.
Benefits
Explaining the working of the VNM model, Superintending Engineer and Nodal Officer (Solar) at <a href="https://www.cspdcl.co.in/" target="_blank" rel="noopener">Chhattisgarh State Power Distribution Company</a>, Bimbisar, said a generation meter is installed at the utility’s common transformer, and the beneficiaries receive electricity credits individually based on their respective shares under the VNM arrangement, through meters with VNM-specific programming.
The state government recently announced an additional subsidy of up to ₹30,000 (~$332), bringing the current upfront cost of setting up a rooftop solar system to ₹27,000 (~$299) per prosumer. He added that with the additional state government subsidy, the payback period could be reduced to a year or less.
“The VNM model is highly beneficial for residential households with roof space constraints for multiple projects,” added Bimbisar.
Maintenance of the rooftop solar system under the VNM arrangement is easier and cheaper.
The 60 kW project was set up using 9,600 sq ft of rooftop space, avoiding the need to install separate projects for all 20 beneficiaries. Providing a boost to VNM projects, the Chhattisgarh State Electricity Regulatory Commission has also <a href="http://mercomindia.com/chhattisgarh-clarifies-virtual-net-metered-solar-projects-can-be-off-site" target="_blank" rel="noopener">clarified</a> that a solar project under the VNM framework can be located at a site different from the consumer&#8217;s premises.
VNM Model Expansion 
Bimbisar said that the DISCOM is also planning to take the VNM model to a few villages in Chhattisgarh, where they will set up rooftop solar projects to benefit 50–60 households. Bimbisar said they have sent a proposal to the Union Government regarding the disbursement of subsidies for the VNM project.
“In villages, consumers usually don’t consume more than 200 units of electricity a month. This model allows for reducing the upfront cost. We are hoping to extend the VNM model within the next few months. We have also found vendors willing to execute the project. They can avail the subsidy under PM Surya Ghar program.”
He said the VNM model will also boost installations under PM Surya Ghar as the program allows even houses without proper roof space to avail the benefits.
According to DISCOMs, the major challenge lies in convincing prospective prosumers to invest in this power procurement model for 25 years.
Singh, one of the residents, added that DISCOMs were also not prepared for this, as it was the first VNM project. “The billing was delayed by 5–6 months after installation, and the energy was getting accumulated in the meter.”
Mercom India has been hosting a multi-city C&amp;I Clean Energy Meet series to raise awareness among businesses about the benefits of shifting to renewable energy sources. The next event will be <a href="https://www.mercomindia.com/event/c-and-i-clean-energy-meet-2026-coimbatore" target="_blank" rel="noopener">held</a> in Coimbatore on February 5, 2026.

					</table>The Jaipur Vidyut Vitran Nigam (<a href="https://www.bijlimitra.com/custumerLoginPage" target="_blank" rel="noopener">JVVNL</a>) has filed a petition before the Rajasthan Electricity Regulatory Commission (<a href="https://rerc.rajasthan.gov.in/" target="_blank" rel="noopener">RERC</a>) to allow virtual net metering (VNM) and group net metering (GNM) in the state.
The petition, filed on behalf of Ajmer Vidyut Vitran Nigam (AVVNL) and Jodhpur Vidyut Vitran Nigam (<a href="https://jdvvnl.bijlimitra.com/jdvvnlmitra/custumerLoginPage" target="_blank" rel="noopener">JdVVNL</a>), seeks amendments to the RERC’s Grid-Interactive Distributed Renewable Energy Generating Systems (DREGS) Regulations, 2021.
The existing regulations currently <a href="https://www.mercomindia.com/rajasthan-waives-charges-domestic-rooftop-solar" target="_blank" rel="noopener">cover</a> net metering, net billing, and grid-connected renewable energy systems operating behind the meter, but do not provide for VNM and GNM arrangements.
National Policy Alignment
The Government of India issued operational guidelines for the payment security mechanism and central financial assistance, applicable to the renewable energy service company (RESCO) models and utility-led aggregation models under the PM Surya Ghar: Muft Bijli Yojana.
The RERC DREGS Regulations, 2021, already provide for the RESCO models, but do not currently allow VNM and GNM, which are critical for implementing utility-led aggregator models. Other state electricity regulatory commissions, including those of Delhi, Odisha, Maharashtra, and Assam, have already notified enabling provisions for these mechanisms. The Rajasthan distribution companies (DISCOMs) are seeking to align the state regulations with these national and inter-state practices.
Rationale for Amendments
According to the petitioners, the introduction of VNM and GNM will allow broader participation of both government institutions and domestic consumers in rooftop solar adoption. Rajasthan has over 100,378 government electricity connections with a cumulative sanctioned load of 1.19 GW.
At the same time, government departments have accumulated significant unpaid electricity bills, with outstanding dues amounting to ₹15.05 billion (~$179 million) as of May 31, 2025. This has placed financial stress on the DISCOMs, which are forced to resort to high-cost borrowing to maintain operations.
The Rajasthan government has already directed 100% rooftop solar coverage of state government buildings through an order dated February 1, 2024, with the Rajasthan Renewable Energy Corporation designated as the nodal agency.
Proposed Regulatory Provisions
The DISCOMS have proposed that VNM and GNM eligibility be extended only to domestic category consumers and government connections.
For domestic consumers, the maximum sanctioned load under this mechanism will be capped at 10 kW, while no such cap is proposed for government connections. The maximum capacity of individual renewable energy systems under VNM or GNM will be capped at 1 MW.
All applications from government connections will require a mandatory technical feasibility study. In contrast, domestic consumers with a capacity of up to 10 kW will continue to be exempt from such studies, except in VNM and GNM applications.
The petition proposes that government connections opting for VNM or GNM under RESCO mode must pay 50% of the cross-subsidy and additional surcharge. Additionally, 100% wheeling charges must be levied at the 11 kV level or the respective voltage level, based on the sanctioned load, until low tension-level wheeling charges are defined.
Wheeling Charges and BESS
The petition also incorporates incentives for integrating battery energy storage systems (BESS). A 75% waiver on wheeling charges is requested for systems with at least 5% of solar capacity supported by BESS. For higher storage capacities, an additional 1% waiver was requested for every 1% increase in BESS capacity, up to a maximum of 30%.
Systems with BESS capacities exceeding 30% of solar will be eligible for a complete 100% waiver of wheeling charges. The petitioners contended that the proposal aligns with the Government of India’s advisory dated February 18, 2025, which recommends integrating storage with rooftop solar systems to enhance supply reliability.
The petition further states that wheeling losses will be applied based on the voltage level of energy drawal. For low-tension (LT) consumers, approved distribution losses will be applied until specific LT-level wheeling losses are determined.
This approach follows practices adopted in other states, such as Madhya Pradesh, where voltage-wise losses are applied. In contrast, Maharashtra has exempted VNM and GNM connections till the capacity of rooftop solar reaches 5,000 MW.
Financial Implications
The DISCOMs emphasized that government non-payment of electricity bills has created a financial liability of ₹15.05 billion (~$179 million) as of May 31, 2025. This liability compels them to take high-cost loans, which ultimately increases the tariff burden on all consumer categories.
The solarization of government connections through VNM and GNM will reduce reliance on grid purchases for these consumers, lower their bills, and release the DISCOMs from recurring financial strain. Moreover, the surplus solar power generated by government buildings can help optimize state-level power purchase costs.
The proposed levy of partial surcharges and wheeling charges on government connections is intended to allow recovery of infrastructure costs while still incentivizing adoption of rooftop solar.
Recently, RERC <a href="https://www.mercomindia.com/rajasthan-regulator-approves-tariffs-for-488-mw-solar-projects-under-kusum" target="_blank" rel="noopener">approved</a> JdVVNL’s tariffs ranging from ₹2.68 (~$0.030)/kWh to ₹3.66 (~$0.041)/kWh for solar projects with a cumulative capacity of 488 MW to be set up across Rajasthan under Component – C of the Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM KUSUM) program.

DISCOMs Move RERC to Allow Virtual and Group Net Metering in Rajasthan

The Delhi Electricity Regulatory Commission (<a href="http://www.derc.gov.in/" target="_blank" rel="noopener noreferrer">DERC</a>) has amended its regulations on group net metering and virtual net metering for renewable energy. In the amendment, the regulator has modified its guidelines on the applicability of virtual net metering.
Virtual net metering is an arrangement for consumers who do not have a suitable roof for installing a solar power generating system but want access to a solar net-metering facility. With virtual net metering, consumers can own a part of a collectively-owned solar power generating system. All energy produced by such a solar system will be fed into the grid through an energy meter, and the exported energy, as recorded by that meter, will be credited to the electricity bill of each participating consumer based on beneficial ownership.
The purpose of this group net-metering framework is to help maximize the utilization of rooftop space for solar energy generation for consumers with multiple buildings and service connections.
The amendment has broadened the scope of applicability for virtual net metering connections. Earlier, it applied only to residential consumers, including group housing societies, government offices or local authorities, and renewable energy generators registered under Mukhya Mantri Kisaan Aay Badhotari Yojna.
Now, the amendment says that virtual net metering will be applicable for consumers under the domestic category as well as consumers such as hospitals, colleges, schools, other institutions run or managed by charitable institutions, non-profit organizations, trusts that do not fall under the category of domestic consumers, and renewable energy generators registered under Delhi’s solar program.
The DERC had <a href="https://mercomindia.com/derc-group-virtual-net-metering/" target="_blank" rel="noopener noreferrer">finalized</a> the group and virtual net metering guidelines in June 2019. It had set the minimum project capacity at 5 kW while the maximum was 5 MW at a single location. The DERC had issued draft guidelines in <a href="https://mercomindia.com/derc-draft-policy-virtual-net-metering/" target="_blank" rel="noopener noreferrer">December 2018</a>.
Mercom’s Renewable Energy Regulatory <a href="https://mercomindia.com/product/mercoms-renewable-energy-regulatory-updates/" target="_blank" rel="noopener noreferrer">Updates</a> has been keeping a track of net metering regulations across India.
In 2018, the Delhi government <a href="https://mercomindia.com/delhi-govt-solar-residential-program-security/" target="_blank" rel="noopener noreferrer">approved</a> the <a href="https://mercomindia.com/delhi-housing-societies-rooftop-solar-free-installation/" target="_blank" rel="noopener noreferrer">Mukhyamantri Solar Power Program</a> to give the necessary and required boost to solar power adoption in the national capital. This program applies to domestic category consumers in Delhi.
