Maharashtra is India’s largest state by electricity consumption. With Mumbai, Pune, Nagpur, and Nashik among the country’s most energy-intensive cities, Maharashtra’s rooftop solar market is both large and complex.
The complexity comes from distribution: Maharashtra has several electricity distribution licensees (DISCOMs) serving different geographies: MSEDCL across most of the state, and Adani Electricity Mumbai, Tata Power and BEST in Mumbai, with Torrent Power supplying Bhiwandi within MSEDCL’s area. (MSETCL is the state transmission company, not a DISCOM.) Each has its own application process, its own net metering portal, and its own service quality track record.
This guide breaks down the policy framework, explains how net metering works under MERC (Maharashtra Electricity Regulatory Commission), details the PM Suryaghar implementation across the DISCOMs, and gives you a practical framework for choosing the right installation pathway.
Key takeaway. Maharashtra’s rooftop solar rules come from MERC’s Grid Interactive Rooftop Renewable Energy Generating Systems Regulations, 2019, as amended, which allow net metering up to your sanctioned load or contract demand (maximum 5 MW), subject to distribution transformer capacity. PM Suryaghar subsidy (up to ₹78,000) is available to residential consumers of MSEDCL, Adani Electricity, Tata Power and BEST. MAHAURJA is Maharashtra’s state nodal agency for solar programmes. Heaven Green Energy serves Maharashtra consumers from its Chhatrapati Sambhajinagar office, with expertise across all major DISCOMs.
Choosing the right pathway through Maharashtra’s multi-DISCOM landscape is as important as choosing the right panels.
MERC Net Metering Regulations: The Legal Foundation
Maharashtra’s solar policy for consumers rests on the MERC (Maharashtra Electricity Regulatory Commission) (Grid Interactive Rooftop Renewable Energy Generating Systems) Regulations, 2019, amended in 2023 (First Amendment) and 2024 (Second Amendment). They establish the rights and obligations of consumers, DISCOMs, and generators.
Key MERC provisions:
Non-discriminatory access: DISCOMs must allow net metering to eligible consumers on a non-discriminatory, first-come-first-served basis at each distribution transformer or feeder. The cumulative rooftop capacity on a transformer is capped at 70% of its rating, unless the DISCOM allows more after a load study.
System size limits: Solar system capacity must not exceed the consumer’s sanctioned load or contract demand, and under net metering is capped at 5 MW; the minimum is 1 kW. The MERC website publishes the current regulations and orders.
Settlement mechanism: If you export more units than you import in a billing period, the excess is carried forward to the next billing period as credited units. Unadjusted credited units at the end of each financial year are bought by the DISCOM at the generic tariff approved by MERC for that year, and the carried-forward balance resets to zero. If the credit keeps growing for three consecutive financial years, half is paid in cash and half credited to the bill.
Grid support charges: Under the 2023 amendment, grid support charges are not levied until rooftop installations in the state reach 5,000 MW, and consumers with sanctioned load up to 10 kW are exempt from them in any case.
Interconnection timeline: The regulations set timelines for each step of the application, and a DISCOM that delays an activity must compensate the consumer at ₹500 per day of delay.

PM Suryaghar in Maharashtra: Which DISCOMs Participate?
All major Maharashtra DISCOMs participate in PM Suryaghar. The scheme is administered through the national portal (pmsuryaghar.gov.in), where you apply and choose a registered vendor.
DISCOM-wise PM Suryaghar participation:
| DISCOM | Service area | PM Suryaghar available | Application portal |
|---|---|---|---|
| MSEDCL | Most of Maharashtra, including some Mumbai suburbs | ✓ Yes | National portal |
| Adani Electricity | Mumbai suburbs | ✓ Yes | National portal |
| Tata Power | Parts of Mumbai | ✓ Yes | National portal |
| Torrent Power | Bhiwandi (within MSEDCL’s area) | Check with Torrent Power | National portal |
| BEST (Brihanmumbai Electric Supply) | Mumbai island city | ✓ Yes | National portal |

💡 Fast tip
Your DISCOM is determined by your electricity bill header, not your city. Many Mumbai residents are surprised to find they have an Adani Electricity or Tata Power connection rather than MSEDCL. Check your bill header before selecting an installer, the DISCOM decides the net metering process you follow.
MAHAURJA: Maharashtra’s Solar Nodal Agency
MAHAURJA (Maharashtra Energy Development Agency) is Maharashtra’s state nodal agency for energy development, operating under the Department of Energy. For solar, MAHAURJA’s key roles include:
State renewable energy programmes: MAHAURJA is the state agency for renewable energy programmes run with MNRE (Ministry of New and Renewable Energy). PM Suryaghar applications themselves are made on the national portal and processed by your DISCOM; under the scheme there is no state tendering or empanelment of rooftop vendors.
Renewable Purchase Obligation: Maharashtra has a Renewable Purchase Obligation (RPO) framework set by MERC for obligated entities, including large captive and open access consumers.
Consumer guidance: The MAHAURJA website provides consumer-facing guides on solar installation, subsidy processes, and DISCOM contact information.
MEDA and MAHAURJA: MAHAURJA is the name under which MEDA (Maharashtra Energy Development Agency) runs its website and schemes. This includes the administration of PM-KUSUM solar pump subsidies for Maharashtra farmers, see our PM-KUSUM Maharashtra application guide for that separate process.
Maharashtra Green Energy Obligation: What Large Consumers Must Know
Maharashtra’s Green Energy Obligation (GEO), implemented through MERC Renewable Purchase Obligation (RPO) regulations, requires large commercial and industrial consumers to source a minimum percentage of their electricity from renewable sources.
Who is covered: Obligated entities as defined in MERC’s RPO regulations, which include certain captive and open access consumers. The required percentages rise year by year, so verify the current year’s targets in MERC’s RPO regulations at merc.gov.in. Under MERC’s rooftop regulations, solar consumed under net metering, net billing or behind-the-meter arrangements counts towards an obligated consumer’s RPO.
Compliance options:
- Install captive solar (rooftop or ground-mount) to generate the required renewable percentage
- Purchase Renewable Energy Certificates (RECs) from the national REC market (IEXC / PXIL)
- Sign a Power Purchase Agreement (PPA) with a renewable energy project
For large commercial consumers in Maharashtra, on-site captive solar is typically the lowest-cost compliance pathway, and it simultaneously reduces electricity bills.
📘 Regulation note
MERC's regulations and orders set RPO targets, the generic tariff used for year-end surplus purchase, and net metering rules. Always verify the current year's provisions on the MERC website (merc.gov.in) or through an experienced installer before finalising your financial model, rates change between orders.
The Maharashtra Solar Pathway Selector (Framework)
Choosing the right installation pathway in Maharashtra requires matching your DISCOM to the right process. The Maharashtra Solar Pathway Selector is Heaven Green Energy’s proprietary framework for identifying the smoothest path to solar commissioning based on your DISCOM and consumer category.
Step 1: Identify your DISCOM
Look at your electricity bill header. The DISCOM name is printed prominently, MSEDCL, Adani Electricity, Tata Power, Torrent Power, or BEST.
Step 2: Assess process complexity by DISCOM
| DISCOM | Consumer base | PM Suryaghar process | Typical timeline | Process notes |
|---|---|---|---|---|
| MSEDCL | Rest of Maharashtra | National portal + registered vendor | 60 to 90 days | Largest volume, good national portal integration |
| Adani Electricity | Mumbai suburbs | National portal + AEL online portal | 45 to 60 days | Faster processing, dedicated AEL solar desk |
| Tata Power | Mumbai city | National portal + Tata Power portal | 50 to 70 days | Good documentation; multi-layer approval |
| Torrent Power | Bhiwandi region | National portal | 60 to 80 days | Smaller area; manageable queue |
| BEST | Mumbai Municipal | National portal | 70 to 90 days | Slower processing; smaller solar team |
Step 3: Verify installer registration
For the PM Suryaghar subsidy, your installer must be a vendor registered on the national portal. Verify at pmsuryaghar.gov.in that your installer is registered and serves your area.
Step 4: Confirm sanctioned load capacity
In Mumbai’s dense residential areas, many older apartments have sanctioned loads of 1 to 2 kW, limiting solar capacity to 1 to 2 kW unless a load enhancement is processed. For Pune and Nashik (MSEDCL territory), sanctioned loads are typically higher.
Step 5: Account for terrace/roof access
In Mumbai, many residential buildings are housing societies with shared rooftops. A housing society solar installation requires the general body’s approval and typically follows a collective installation model, see our solar for housing society guide.
Mumbai Consumers: A Special Case
Mumbai’s solar market is uniquely complex because of its multi-DISCOM structure, high-rise buildings, high real estate costs, and a consumer culture that includes both early adopters and skeptics.
Why Mumbai solar installations take longer:
- High-rise buildings have structural considerations for mounting, engineering sign-off is often required
- Multi-DISCOM geography means application processes vary across the same PIN code
- Housing society approvals add 30 to 60 days in multi-story buildings
- The BEST area (island city) has lower solar installer density
Mumbai tariff context: MSEDCL’s Mumbai tariff and Adani Electricity’s Mumbai tariff are both among India’s highest LT residential rates, ₹8 to 12/kWh for consumers above the BPL threshold. This creates strong ROI for solar despite the installation complexity. For a full cost breakdown by system size, see our solar installation cost in Mumbai guide.

Frequently Asked Questions
Is MSEDCL required to allow net metering in Maharashtra?
Yes, subject to the conditions in MERC’s Grid Interactive Rooftop RE Regulations, 2019. MSEDCL and the other DISCOMs must allow net metering to eligible consumers on a non-discriminatory, first-come-first-served basis, as long as the system is within your sanctioned load (and 5 MW) and the distribution transformer’s rooftop capacity (70% of its rating, unless a load study allows more). A DISCOM that delays an activity must pay ₹500 per day. If your application is rejected without a valid reason, you can escalate through the DISCOM’s grievance forum.
What is MAHAURJA and how does it differ from MSEDCL?
MAHAURJA (Maharashtra Energy Development Agency) is the state’s renewable energy nodal agency; it promotes solar and runs state renewable programmes such as PM-KUSUM. MSEDCL (Maharashtra State Electricity Distribution Company Limited) is the electricity distribution company that supplies power to most of Maharashtra. Net metering rules are set by MERC; MSEDCL delivers the grid connection and net metering.
How long does PM Suryaghar take in Maharashtra?
The full timeline from application to net meter commissioning is typically 60 to 90 days for MSEDCL consumers and 45 to 70 days for Adani Electricity Mumbai consumers. The main variable is DISCOM inspection scheduling, Adani Electricity tends to be faster. Document completeness at application stage is the single biggest factor you can control.
Does Mumbai’s Adani Electricity have a different PM Suryaghar process than MSEDCL?
The subsidy and national portal are the same. The difference is in the DISCOM-side processing. Adani Electricity has a dedicated solar team and online application portal that integrates with the national portal, which in our experience often gives faster feasibility approval than some MSEDCL circles. Ensure your installer is a registered vendor on the national portal who serves your area.
Can I get solar on a Mumbai apartment with a 1 kW sanctioned load?
Yes, but only a 1 kW system, solar capacity cannot exceed sanctioned load under MERC rules. To install more, you’d need a load enhancement to increase your sanctioned load. In many Mumbai apartments, a load enhancement from 1 kW to 2 to 3 kW is feasible and takes 2 to 4 weeks through your DISCOM.
What is Maharashtra’s RPO target for commercial consumers?
Under MERC’s Renewable Purchase Obligation framework, obligated entities, including certain captive and open access consumers, must source a specified and rising percentage of their electricity from renewable sources. Verify the current year’s targets in MERC’s RPO regulations at merc.gov.in. Rooftop solar consumed under net metering counts towards an obligated consumer’s RPO.
Is it worth installing solar in Pune vs Mumbai?
Both are financially attractive. Pune (MSEDCL) has a simpler installation process for standalone homes and lower-rise buildings. Mumbai has higher electricity tariffs, especially for Adani Electricity and Tata Power consumers, meaning better per-unit savings. However, Mumbai’s high-rise installations have higher complexity costs (structural assessment, housing society approval). For houses and standalone buildings, Pune often has faster timelines and lower installation costs, see our solar installation cost in Pune guide for size-by-size pricing.
