15 Green Energy IPOs in India to Know Across Renewable Energy Sectors

India’s renewable energy growth creates new markets for project developers, equipment makers, and EPC providers. Green Energy IPOs in India give these businesses access to capital for expansion, capacity building, and other stated goals.

Green energy IPOs in India offer one way to study this growing business ecosystem. But not every power company operates in renewable energy.

This blog covers businesses linked to various renewable sectors. You will learn how each company earns revenue, where it fits in the energy value chain, and what its business model means for investors.

Understanding the value chain of green energy IPOs in India

Not every energy company offers the same business exposure. Some sell equipment, while others earn money from power generation. This difference shapes their costs, cash flow, and growth needs.

For this list, we group green energy IPOs in India into four key segments:

• Solar manufacturing and EPC: Equipment makers sell products. EPC providers earn revenue from designing and building energy projects.
• Renewable power generation: Independent power producers (IPPs) own or operate projects. They earn from electricity sales, tariffs, and contracts.
• Wind and clean energy equipment: Manufacturers supply turbines, parts, and other tools for clean power projects.
• Energy transition infrastructure: Businesses support storage, grid systems, and other energy technologies. 
• Different business models create different opportunities and risks across Green Energy IPOs in India.

One important point: An IPO’s issue size does not show business strength. Investors must also review revenue, profits, debt, cash flow, and project execution. A large offering cannot guarantee future returns.

15 green energy IPOs in India across different renewable energy sectors

We have selected 15 Green Energy IPOs in India across various renewable energy sectors. Let’s look at them one by one.

Solar Manufacturing Companies with Public Market Exposure

Green Energy IPOs in India include several solar manufacturers that participate in different stages of the renewable energy value chain.

1. Waaree energies

Waaree Energies combines solar module manufacturing with EPC and energy-related activities. Its IPO proceeds were intended to support backward integration across solar modules, cells, and ingot-wafer facilities. This gives the company exposure to both equipment sales and deeper manufacturing capabilities.

• IPO filing date: Verify through the company’s official IPO documents.
• IPO issue period: October 21–23, 2024.
• Listing date: October 28, 2024, on NSE and BSE.
• Estimated issue value: ₹4,321 crore.
• What to examine: Capacity utilisation, export dependence, input costs, and the capital required for backward integration.

Waaree’s expansion strategy matters because greater manufacturing depth can improve supply control. However, it also increases exposure to technology changes, capital expenditure, and pricing pressure. Its reported 2024–25 annual report identifies backward integration as a key use of green energy IPOs in India. 

2. Premier energies

Premier Energies operates across solar cell and module manufacturing, with related project activities. Unlike a company focused only on module assembly, its cell manufacturing operations provide exposure to an earlier stage of the solar value chain. Its product mix and technology upgrades are important when assessing future margins.

• IPO filing date: August 27, 2024
• IPO issue period: August 27–September 3, 2024.
• Listing date: September 3, 2024.
• Estimated issue value: Approximately ₹2,830 crore.
• What to examine: Cell-to-module capacity, technology upgrades, working capital, and dependence on large customers.

Premier’s business should be assessed through its manufacturing mix rather than total capacity alone. Investors should compare cell and module output, operating margins, and expansion spending. NSE filings describe its business through solar cells, modules, and related project activities. 

3. Vikram solar

Vikram Solar is a solar module manufacturer serving utility-scale, commercial, and other solar applications. Its expansion plans have focused on increasing manufacturing capacity, including a reported 5 GW facility in Tamil Nadu. Such expansion can improve scale, but it also requires strong demand and efficient factory operations.

• IPO filing date: September 30, 2024, based on the company’s DRHP.
• IPO issue period: August 2025.
• Listing period: August 2025.
• Estimated issue value: Approximately ₹1,500 crore.
• What to examine: Factory utilisation, module technology, execution of new facilities, and price competition.

In November 2025, an exchange filing reported the addition of a 5 GW module production facility in Tamil Nadu, taking total manufacturing capacity to 9.5 GW. The figure should be read as manufacturing capacity, not as a guarantee of equivalent sales or profit. 

4. Saatvik green energy

Saatvik Green Energy belongs to the solar manufacturing segment and has pursued public-market funding to support its expansion. Its IPO documents should be examined closely because the company’s manufacturing scale, project exposure, and customer mix affect its risk profile.

• IPO filing date: September 2025, based on its Red Herring Prospectus.
• IPO status: Offer documents were filed and published; final listing status must be checked against current exchange records.
• Estimated issue value: Reported proposal of approximately ₹900 crore, including a fresh issue and offer for sale.
• What to examine: Final issue structure, operating capacity, customer concentration, and use of IPO proceeds.

Saatvik’s prospectus and exchange filings should be used to confirm the final issue size and listing details before publication. Its manufacturing capacity should also be separated into operational, expanded, and planned capacity. 

5. Emmvee photovoltaic power

Emmvee Photovoltaic Power operates in solar photovoltaic manufacturing and is part of India’s growing domestic solar equipment base. Its offer documents provide information on manufacturing capacity, technology, financial performance, and the planned use of capital.

• IPO filing date: November 15, 2025, according to SEBI records.
• IPO status: Verify the latest exchange and company disclosures before publication.
• Estimated issue value: To be confirmed from the final offer document.
• What to examine: Final issue size, manufacturing capacity, technology mix, customer concentration, and capital expenditure plans.

Emmvee’s capacity should be compared with other manufacturers using the same measurement date. Industry comparisons can become misleading when one company reports operational capacity while another includes planned or recently announced facilities. Its offer documents also provide a basis for reviewing technology and competitive positioning. 

Solar manufacturers earn revenue by selling equipment. Renewable power producers follow a different model: They invest in projects and earn income from the electricity those assets generate.

Renewable Energy Developers and Power Generation IPOs

Some Green Energy IPOs in India focus on developing and operating renewable power projects rather than manufacturing equipment.

6. NTPC green energy

NTPC Green Energy is the renewable energy arm of state-owned power producer NTPC. Its model covers utility-scale renewable projects, including solar and wind, along with emerging areas such as green hydrogen and energy storage. Its parent company provides access to project development experience and large-scale energy infrastructure.

• IPO filing date: September 18, 2024, based on NTPC’s official disclosure.
• IPO issue period: November 19–22, 2024.
• Listing date: November 27, 2024, on NSE and BSE.
• Issue value: ₹10,000 crore.
• Issue structure: Fresh issue.
• What to examine: Project commissioning, debt requirements, renewable capacity under development, and the pace of cash flow generation.

The IPO proceeds were intended to support the company’s growth and general corporate purposes. Investors should distinguish NTPC Green Energy’s operational projects from its wider development pipeline. A large proposed pipeline does not automatically translate into near-term revenue. 

7. ACME solar holdings

ACME Solar Holdings develops, owns, and operates renewable power projects. Its portfolio includes solar, wind, and hybrid renewable assets. The company earns revenue through electricity sales, mainly under long-term contracts. This makes its PPA terms, project availability, and financing costs important indicators of business performance.

• IPO filing date: July 4, 2024, when its draft offer documents were filed with SEBI.
• IPO issue period: November 6–8, 2024.
• Listing date: November 13, 2024.
• Estimated issue value: Approximately ₹2,900 crore.
• Issue structure: Fresh issue and offer for sale.
• What to examine: PPA duration, tariff rates, debt servicing, generation performance, and project concentration.

An IPP’s revenue depends on electricity generation and contractual payment terms. For ACME Solar, readers should examine how much capacity is operational versus under construction. They should also assess whether new projects can generate enough cash flow to support future debt obligations. 

8. Juniper green energy

Juniper Green Energy is an independent power producer that develops, builds, owns, operates, and maintains utility-scale renewable projects. Its business model is based on owning energy assets rather than selling solar equipment. The company’s portfolio and project pipeline should be assessed alongside its funding needs and debt exposure.

• IPO filing date: Draft offer documents were filed with SEBI in June 2025.
• IPO issue period: July 30–August 3, 2026.
• Listing date: August 6, 2026.
• Issue value: ₹1,800 crore.
• Issue structure: Fresh issue.
• What to examine: Project debt, commissioning timelines, operational capacity, PPA terms, and interest costs.

Juniper reduced its proposed IPO size from ₹3,000 crore to ₹1,800 crore before the offering. Its reported debt position also makes capital structure an important area for review. Capacity expansion should therefore be considered alongside the company’s ability to service debt and maintain project-level cash flow. 

9. Clean Max enviro energy solutions

CleanMax focuses on renewable power for commercial and industrial customers. Its business includes developing renewable projects and supplying green power to businesses through contractual arrangements. This creates exposure to corporate clean energy demand, including demand from technology companies and data centres.

• IPO filing date: Verify the exact DRHP filing date through the company’s official IPO documents.
• IPO issue period: February 23–25, 2026.
• Listing date: March 2, 2026.
• Issue value: Approximately ₹3,100 crore.
• Issue structure: Fresh issue and offer for sale.
• Reported capacity: 2.80 GW operational capacity and 3.17 GW contracted capacity, according to an NSE filing.
• What to examine: Customer concentration, contracted revenue, project debt, commissioning pace, and corporate power demand.

CleanMax’s commercial and industrial focus separates it from developers that mainly supply electricity to state utilities. However, corporate customers may have different contract terms, credit profiles, and energy needs. The company’s operational and contracted capacity figures should not be treated as identical measures. 

10. TruAlt bioenergy

TruAlt Bioenergy should be treated separately from solar and wind IPPs. The company produces ethanol and other biofuel-related products, while its operations also generate by-products such as carbon dioxide. Its subsidiary, Leafiniti, operates in compressed biogas (CBG), connecting the business to bioenergy and waste-based fuel production.

• IPO filing date: September 25, 2025
• IPO issue period: September 25–29, 2025.
• Listing date: October 3, 2025.
• Issue value: ₹839.28 crore.
• Issue structure: Fresh issue and offer for sale.
• Reported ethanol capacity: 1,400 kilolitres per day as of March 31, 2024.
• What to examine: Feedstock costs, government blending policies, working capital, plant utilisation, and the economics of multi-feedstock production.

Bioenergy revenue depends on feedstock availability, plant efficiency, fuel demand, and policy conditions. Unlike solar and wind projects, ethanol production involves recurring raw material costs. 

Solar EPC and Decentralized Energy Companies

Solar EPC companies represent another segment of Green Energy IPOs in India, supporting the development and installation of renewable energy systems.

11. GK energy

GK Energy provides EPC services for solar-powered agricultural water pump systems. Its business is closely linked to government-supported agricultural solarisation, particularly the PM-KUSUM scheme. The company also operates in rooftop solar and related energy solutions. Its recent battery storage project shows potential expansion beyond agricultural pumping.

• IPO filing date: Verify from the company’s DRHP and SEBI records.
• IPO issue period: September 19–23, 2025.
• Listing date: September 26, 2025.
• Estimated issue value: ₹464 crore.
• What to examine: Government scheme dependence, project receivables, execution timelines, and customer concentration.

GK Energy’s solar pump business differs from a conventional rooftop EPC company because project demand can depend on government allocations and subsidy-linked programmes. In September 2026, the company also received an award for a 150 MW/300 MWh battery energy storage system in Maharashtra. 

12. Solarworld energy solutions

Solarworld Energy Solutions provides turnkey solar EPC services for public-sector undertakings and commercial and industrial customers. Its scope includes project design, procurement, construction, and commissioning. The company has also proposed investment in a solar cell manufacturing project, giving it some exposure beyond EPC execution.

• IPO filing date: Prospectus dated September 25, 2025.
• IPO issue period: September 23–25, 2025.
• Listing date: September 30, 2025.
• Issue value: ₹490 crore.
• Issue structure: Fresh issue of ₹440 crore and offer for sale of ₹50 crore.
• Reported project metric: Completed projects of 253.67 MW AC/336.17 MW DC and ongoing EPC projects of 765 MW AC/994 MW DC as of July 31, 2025.
• What to examine: Project execution, working capital, receivables, and the funding needs of its proposed 1.2 GW TOPCon cell facility.

Solarworld’s project figures show why completed and ongoing capacity should be reported separately. An ongoing project contributes to the order pipeline, but its revenue recognition and cash collection depend on execution and contract milestones. 

13. Alpex solar

Alpex Solar combines solar PV module manufacturing with EPC services, including solar-powered agricultural water pumps. It therefore does not fit into a pure EPC category. Its business connects equipment production with project delivery, especially in solar pumping and distributed applications.

• IPO filing date: Verify from the company’s offer documents.
• IPO issue period: February 8–12, 2024.
• Listing date: February 15, 2024, on NSE Emerge.
• Issue value: ₹74.52 crore at the IPO stage.
• Company-specific metric: The FY2023–24 annual report reported more than 12,000 solar water pumps installed across India.
• What to examine: Manufacturing utilisation, solar pump demand, government programme exposure, and the balance between product and EPC revenue.

Alpex’s solar pump activity makes it relevant to decentralised energy applications. However, readers should separate revenue from module sales, pump systems, and EPC services when comparing it with other companies in this section. 

14. Sahaj solar

Sahaj Solar operates across solar module manufacturing, solar pumping systems, and EPC services. Its business serves distributed solar applications rather than focusing only on large utility-scale power plants. The company’s solar pump and module activities create a link between manufacturing, installation, and agricultural energy use.

• IPO filing date: Verify from the official offer documents.
• IPO issue period: July 11–15, 2024.
• Listing date: July 19, 2024, on NSE Emerge.
• Issue value: ₹52.56 crore.
• Issue structure: Fresh issue.
• Company-specific metric: Its manufacturing plant is located in Bavla, Ahmedabad, Gujarat.
• What to examine: Manufacturing scale, project execution, working capital, subsidy-linked demand, and customer payment cycles.

Sahaj Solar illustrates how smaller renewable businesses can combine products and services. Its performance should not be assessed only through EPC order value because module manufacturing and solar pump sales also affect its revenue mix. 

15. Solarium green energy

Solarium Green Energy provides turnkey solar solutions across design, engineering, procurement, construction, testing, commissioning, and operations and maintenance. Its customer base includes residential, commercial, industrial, and government projects. The company also sells solar equipment such as modules, inverters, and ABT meters.

• IPO filing date: February 6, 2025
• IPO issue period: February 6–10, 2025.
• Listing date: February 13, 2025, on BSE SME.
• Issue value: ₹105.04 crore.
• Issue structure: Fresh issue.
• Company-specific metric: The IPO comprised approximately 54.99 lakh shares at ₹191 per share.
• What to examine: Working capital use, project completion, receivables, and the share of recurring O&M revenue.

Solarium’s service scope covers several customer segments, but the revenue quality may differ across residential, C&I, and government projects. 

What investors should compare across these companies?

Green Energy IPOs in India do not have identical revenue models, so investors should compare companies based on their business models and financial characteristics. A useful comparison should separate:

Factor	Solar and wind IPPs	Bioenergy producers
Main asset	Power generation projects	Processing plants and biofuel facilities
Revenue driver	Electricity sold under contracts or market arrangements	Ethanol, CBG, and related product sales
Key cost	Project financing and operations	Feedstock, energy, and plant operations
Main risk	Delays, generation shortfalls, debt, and payment cycles	Feedstock prices, policy changes, and plant utilisation
Capacity measure	MW or GW of generation capacity	KLPD, tonnes per day, and plant capacity

The central distinction is asset ownership versus production economics. Renewable power developers depend on long-term project cash flows, while bioenergy companies also face recurring input costs and processing risks. 

Therefore, the list of green energy IPOs in India should not be evaluated using one common capacity or profitability measure.

Key factors to examine before investing in green energy IPOs

Sector growth does not remove company-specific risks. Before evaluating green energy IPOs in India, review these factors:

• IPO proceeds: What will the company fund, such as expansion, debt repayment, or working capital?
• Revenue concentration: Does it depend on a few customers or contracts?
• Debt: Can the business manage borrowing costs during expansion?
• Execution: Are projects operational, under construction, or only proposed?
• Cash flow: Does reported profit translate into operating cash flow?
• Policy exposure: The government incentives for green businesses should be assessed as policy support, not guaranteed profit.
• Valuation: How does the issue compare with relevant listed peers?

Conclusion:

Green energy IPOs in India operate across different parts of the value chain. Manufacturers produce solar equipment, while power developers own and operate renewable projects. EPC companies design and build systems, and bioenergy businesses convert feedstock into fuel and related products. Each model carries different capital needs, revenue drivers, and operating risks. 

Therefore, investors should review company financials, IPO documents, debt levels, cash flow, and project execution rather than rely on the sector label alone. The same distinction matters for entrepreneurs assessing manufacturing, EPC, energy services, and other green energy business opportunities in India.
