Maharashtra is India’s largest state by electricity consumption. With Mumbai, Pune, Nagpur, and Nashik among the country’s most energy-intensive cities, and with over 3 lakh consumers having installed rooftop solar by 2025 (MNRE state-wise rooftop solar data, 2025), Maharashtra’s solar market is both large and complex.
The complexity comes from distribution: Maharashtra has six electricity distribution companies (DISCOMs) serving different geographies and consumer categories — MSEDCL, Adani Electricity, Tata Power, Torrent Power, BEST, and MSETCL for EHV consumers. 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 all six DISCOMs, and gives you a practical framework for choosing the right installation pathway.
Key takeaway. Maharashtra’s solar policy is governed by MERC net metering regulations, which mandate that all DISCOMs accept net metering for residential consumers with systems up to 10 kW. PM Suryaghar subsidy (up to ₹78,000) is available through MSEDCL, Adani Electricity, Tata Power, Torrent Power, and BEST. MAHAURJA is Maharashtra’s state nodal agency for solar programmes. Heaven Green Energy serves Maharashtra consumers through empanelled installer partnerships 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) Net Metering Regulations. The current regulations — updated in 2022 and applicable in 2026 — establish the rights and obligations of consumers, DISCOMs, and generators.
Key MERC provisions:
Mandatory net metering acceptance: For residential consumers with systems up to 10 kW sanctioned load, DISCOMs in Maharashtra are mandatorily required to accept net metering applications. A DISCOM cannot refuse a technically valid net metering application from a residential consumer under 10 kW — this is a fundamental consumer right under MERC regulations.
System size limits: Solar system capacity must not exceed the consumer’s sanctioned load. For consumers with load above 10 kW (LT commercial, HT industrial), net metering is available at the DISCOM’s discretion subject to technical feasibility. The MERC website publishes the current regulatory orders and consumer guidance.
Settlement mechanism: Maharashtra uses monthly net metering settlement. Units exported to the grid are credited against units imported in the same billing month. End-of-month credit balance carries forward to the next month. Annual settlement: any accumulated credit at year-end is settled at the MERC-determined feed-in tariff (currently ₹2.50–₹3.50/kWh for different consumer categories and DISCOMs).
Interconnection timeline: DISCOMs must process net metering applications and install bi-directional meters within 30 days of installation completion for systems up to 10 kW, and 60 days for larger systems.
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) with MAHAURJA coordinating state-level implementation.
DISCOM-wise PM Suryaghar participation:
| DISCOM | Service area | PM Suryaghar available | Application portal |
|---|---|---|---|
| MSEDCL | Maharashtra (outside Mumbai) | ✓ Yes | National portal + MSEDCL vendor list |
| Adani Electricity | Mumbai suburban, Dharavi | ✓ Yes | National portal |
| Tata Power | Mumbai city, select areas | ✓ Yes | National portal |
| Torrent Power | Bhiwandi, Shil-Mumbra | ✓ Yes | National portal |
| BEST (Brihanmumbai Electric Supply) | Mumbai Municipal limits | ✓ 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 — empanelment is DISCOM-specific.
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:
PM Suryaghar state coordination: MAHAURJA coordinates Maharashtra’s implementation of PM Suryaghar with MNRE (Ministry of New and Renewable Energy), tracks state-level progress against targets, and provides a state-level grievance escalation channel.
MNRE empanelment support: MAHAURJA supports the state’s solar installer empanelment network, working with DISCOMs to maintain quality standards.
Green Energy Obligation: Maharashtra has a Renewable Purchase Obligation (RPO) framework for large commercial and industrial consumers. MAHAURJA tracks RPO compliance and coordinates renewable energy certificate (REC) issuance for eligible generators.
Consumer guidance: The MAHAURJA website provides consumer-facing guides on solar installation, subsidy processes, and DISCOM contact information.
MEDA to MAHAURJA rebrand: MAHAURJA is the updated name for what was previously MEDA (Maharashtra Energy Development Agency). All historical MEDA schemes and portals now redirect to MAHAURJA.
Maharashtra Green Energy Obligation: What Large Consumers Must Know
Maharashtra’s Green Energy Obligation (GEO) — implemented through MERC RPO regulations — requires large commercial and industrial consumers to source a minimum percentage of their electricity from renewable sources.
Who is covered: HT and EHT consumers with annual consumption above a MERC-specified threshold. As of 2026, MERC requires covered consumers to source 17% of energy from solar and 8% from non-solar renewable sources (the proportions are adjusted annually in MERC tariff orders — verify at merc.gov.in for the current year’s RPO targets).
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 issues tariff orders annually that update RPO targets, feed-in tariff rates, and net metering settlement rules. Always verify the current year's provisions on the MERC website (merc.gov.in) or through an empanelled 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 + empanelled vendor | 60–90 days | Largest volume — good national portal integration |
| Adani Electricity | Mumbai suburbs | National portal + AEL online portal | 45–60 days | Faster processing, dedicated AEL solar desk |
| Tata Power | Mumbai city | National portal + Tata Power portal | 50–70 days | Good documentation; multi-layer approval |
| Torrent Power | Bhiwandi region | National portal | 60–80 days | Smaller area; manageable queue |
| BEST | Mumbai Municipal | National portal | 70–90 days | Slower processing; smaller solar team |
Step 3: Verify installer empanelment for your DISCOM
Not all installers are empanelled for all Maharashtra DISCOMs. Verify at pmsuryaghar.gov.in that your installer is specifically empanelled for your DISCOM — not just listed on the portal.
Step 4: Confirm sanctioned load capacity
In Mumbai’s dense residential areas, many older apartments have sanctioned loads of 1–2 kW — limiting solar capacity to 1–2 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 30–60 days in multi-story buildings
- The BEST area (BMC limits) 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 — ₹8–12/kWh for consumers above the BPL threshold. This creates strong ROI for solar despite the installation complexity. CEEW’s 2025 India solar consumer survey found that Maharashtra urban consumers achieve the shortest payback periods of any Indian state at high LT tariff bands.

Frequently Asked Questions
Is MSEDCL net metering mandatory to accept in Maharashtra?
Yes. Under MERC Net Metering Regulations, MSEDCL and all other Maharashtra DISCOMs are mandatorily required to accept net metering applications from residential consumers with systems up to 10 kW sanctioned load. A technically valid application cannot be refused. If your application is rejected without a valid technical reason, you can escalate to MERC’s consumer grievance cell.
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, coordinates PM Suryaghar implementation at the state level, and tracks RPO compliance. MSEDCL (Maharashtra State Electricity Distribution Company Limited) is the electricity distribution company that supplies power to most of Maharashtra outside Mumbai. MAHAURJA sets policy; 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 60–90 days for MSEDCL consumers and 45–70 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 — resulting in faster feasibility approval (often 10–15 working days vs 20–30 for MSEDCL in some circles). Ensure your installer is specifically empanelled with Adani Electricity on the national portal.
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 2–3 kW is feasible and takes 2–4 weeks through your DISCOM.
What is Maharashtra’s RPO target for commercial consumers?
Under MERC’s Renewable Purchase Obligation framework, large HT/EHT commercial consumers must source a specified percentage of their electricity from renewable sources. As of 2026, MERC requires approximately 17% solar RPO and 8% non-solar RPO for covered consumers. The exact percentages are updated in MERC’s annual tariff order — verify at merc.gov.in for the current year’s requirement.
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.
