STU Group Captive1,402 MW, 50% of operational portfolio
STU Third Party Open Access540 MW, 19% of operational portfolio
STU Capex375 MW, 14% of operational portfolio
Solar1,736 MWp, 62% of operational technology mix
Hybrid and WindHybrid 756 MW, Wind 307 MW
IPORupee Insight on Portfolio Mix
Clean Max is not only a plain solar developer. Its operating mix includes onsite solar, STU-connected power, capex services, wind and hybrid plants. The increasing hybrid share is important because hybrid projects can improve supply profile compared with single-source solar or wind assets.
The company’s STU Group Captive model is a major part of the operational capacity. This model is useful for corporate customers who want renewable energy access with a customized commercial structure. However, regulatory changes in open access, banking, wheeling charges, cross-subsidy surcharge or group captive rules can affect project economics.
Business Segments
The company operates through two main business segments: Renewable Energy Power Sales and Renewable Energy Services.
| Segment | Revenue | % Revenue Contribution | Gross Margin | % Gross Margin | Invested Capital |
| Renewable Energy Power Sales | Rs. 7,192.15 million | 77.09% | Rs. 6,624.19 million | 92.10% | Rs. 107,984.16 million |
| Renewable Energy Services | Rs. 2,050.07 million | 21.97% | Rs. 672.47 million | 32.80% | Rs. 515.00 million |
Segment insight: Renewable Energy Power Sales is the main revenue and gross margin contributor, but it is capital intensive because the company owns and operates assets. Renewable Energy Services is less capital intensive and can provide cash flow support through EPC, O&M and carbon-related services.
Renewable Energy Power Sales Segment
Under this segment, the company sells electricity generated from renewable energy plants through long-term PPAs and EAPAs. The segment includes onsite solar, offsite STU-connected projects and CTU-connected projects.
Onsite Solar
Onsite solar plants are installed within the customer’s premises. As of September 30, 2025, the company had 1,330 onsite solar plants with aggregate capacity of 368.06 MWp across 23 states and union territories in India and internationally across Thailand, the United Arab Emirates and Bahrain, according to the CRISIL Report.
Offsite STU-Connected Projects
Under STU-connected offsite projects, the company supplies renewable power through state transmission networks to customers in the same state. As of September 30, 2025, it had 1,942.26 MW of STU-connected operating capacity, of which 72.20% was under the STU Group Captive model.
CTU-Connected Projects
CTU-connected projects are being developed to supply power through the national grid. As of September 30, 2025, the company had 1,421.10 MW of contracted CTU-connected capacity and was constructing its first CTU-connected plants in Karnataka and Rajasthan.
Retail investor point: CTU-connected projects can expand the company’s addressable market beyond state boundaries, but these projects may involve execution, grid, settlement and regulatory complexity. Investors should monitor how the first CTU-connected projects perform after commissioning.
Renewable Energy Services Segment
Renewable Energy Services include capex services and carbon services. Under capex services, the company helps customers design, develop, construct and maintain renewable energy plants owned by the customer. Under carbon services, the company offers environmental attributes, I-RECs and carbon credit solutions.
Capex ServicesTurnkey development, EPC, evacuation and O&M for customer-owned renewable energy plants.
Carbon ServicesEnvironmental attributes, I-RECs, carbon credits and advisory support for carbon project registration.
Capex Operating Capacity485.78 MW as of September 30, 2025
Service segment insight: Renewable Energy Services can be strategically useful because it does not always require the same level of balance sheet capital as owned power sales. It can also deepen customer relationships and create future cross-selling opportunities.
Operational KPIs
Clean Max tracks several operating metrics including generation exported, capacity under construction, plant availability, customer base, number of PPAs, repeat orders and weighted average PPA tenure.

| Weighted Average PPA Tenor | 22.85 years | 22.73 years | 21.54 years | 20.38 years |
| Weighted Average Realised Tariff | Rs. 4.25 per kWh | Rs. 4.28 per kWh | Rs. 4.47 per kWh | Rs. 4.95 per kWh |
IPORupee Operational Insight
Three numbers stand out for retail investors: customer count, repeat orders and PPA tenure. Clean Max had 555 C&I customers as of September 30, 2025, 71.72% repeat orders in new contracted volumes for the six months ended September 30, 2025 and a weighted average PPA tenor of 22.85 years. These indicate customer stickiness and long-term revenue visibility.
However, the weighted average realised tariff has reduced from Rs. 4.95 per kWh in Fiscal 2023 to Rs. 4.25 per kWh for the six months ended September 30, 2025. Investors should monitor whether lower tariffs are offset by scale, lower cost of project debt, improved PLF, technology mix and better capital efficiency.
Financial Metrics
The company’s revenue from operations increased from Rs. 9,295.82 million in Fiscal 2023 to Rs. 14,957.01 million in Fiscal 2025. For the six months ended September 30, 2025, revenue from operations stood at Rs. 9,329.30 million.
| Financial Metric | Six months ended September 30, 2025 | Fiscal 2025 | Fiscal 2024 | Fiscal 2023 |
| Revenue from Operations | Rs. 9,329.30 million | Rs. 14,957.01 million | Rs. 13,988.37 million | Rs. 9,295.82 million |
| Renewable Energy Power Sales Revenue | Rs. 7,192.15 million | Rs. 11,072.48 million | Rs. 8,663.33 million | Rs. 4,748.15 million |

| Adjusted EBITDA | Rs. 6,700.68 million | Rs. 10,093.31 million | Rs. 7,722.36 million | Rs. 4,245.97 million |
| PAT Attributable to Owners | Rs. 110.30 million | Rs. 278.43 million | Rs. (309.88) million | Rs. (652.69) million |
| Cash PAT | Rs. 1,995.80 million | Rs. 3,250.04 million | Rs. 2,375.03 million | Rs. 1,610.45 million |
| Debt Net of Liquid Assets / Adjusted EBITDA | 9.43 times | 4.80 times | 4.10 times | 2.71 times |
| Cash SG&A / Adjusted EBITDA | 13.25% | 13.38% | 25.87% | 24.20% |
| Cost of Project Debt | 8.93% | 9.19% | 9.47% | 9.60% |
Financial interpretation: EBITDA and cash PAT show operating strength, but reported PAT is much lower because renewable energy businesses are capital intensive and have depreciation, finance cost and project-level debt. Investors should study cash flows, leverage, project debt and return on capital, not only reported profit.
Customer Quality and Contract Visibility
Clean Max serves large commercial and industrial customers. As of September 30, 2025, 94.72% of customers had a credit rating of A- or above or were subsidiaries of multinational corporations with such ratings. This helps the company reduce counterparty risk.
| Particulars | Six months ended September 30, 2025 | Fiscal 2025 | Fiscal 2024 | Fiscal 2023 |
| Number of Customers | 555 | 531 | 454 | 421 |
| Number of New PPAs / Capex Contracts / LOIs Contracted During Period | 59 | 196 | 86 | 131 |
| Capacity Contracted with Repeat Customers | 268.63 MW | 2,130.42 MW | 464.66 MW | 317.00 MW |
| Total Capacity Contracted During Period | 374.56 MW | 2,756.64 MW | 569.90 MW | 612.60 MW |
| Share of Repeat Orders in New Contracted Volumes | 71.72% | 77.28% | 81.53% | 51.75% |
Customer insight: High repeat order share shows that existing customers continue to buy more capacity from the company. This is positive because corporate renewable energy demand can increase over time as companies expand operations or set higher decarbonization targets.
Project Development and Execution Capability
The company has in-house capabilities across land acquisition, regulatory approvals, permitting, evacuation assessment, EPC, O&M and asset management. As of September 30, 2025, it had a 38-member land acquisition, regulatory and permitting team for offsite farms.
As of September 30, 2025, the company had made applications for 1,311.23 MW of power evacuation capacity for STU-connected farms and 1,480.50 MW for CTU-connected farms pending approval. The company also stated that it had contracted a substantial part of land requirements for contracted projects expected to be commissioned by July 31, 2026.
Execution risk: Renewable projects depend on land, transmission connectivity, approvals, debt funding, equipment procurement and timely construction. Delay in any of these can affect commissioning timelines and future revenue conversion.
Competitive Strengths
C&I Renewable Energy LeaderThe company is India’s largest C&I renewable energy provider by operational, owned and managed capacity as of October 31, 2025, according to the CRISIL Report.

- Regulatory risk: Changes in open access, group captive rules, banking, wheeling charges, cross-subsidy surcharge or renewable energy policy can affect project economics.
- Leverage risk: Debt net of liquid assets to adjusted EBITDA stood at 9.43 times for the six months ended September 30, 2025.
- Tariff pressure: Weighted average realised tariff declined from Rs. 4.95 per kWh in Fiscal 2023 to Rs. 4.25 per kWh for the six months ended September 30, 2025.
- Technology and resource risk: Solar and wind output depends on irradiation, wind speeds, weather and plant availability.
- Customer contract risk: Although PPAs are long-term, any customer default, renegotiation or termination can affect cash flows.
- CTU project risk: CTU-connected projects are still being developed and may involve additional complexity compared with established STU-connected projects.
IPORupee Review and Insight
Business Quality View
Clean Max operates in a structurally strong sector because large corporates are increasingly targeting renewable energy procurement, lower carbon emissions and Net Zero commitments. The company’s C&I-focused model is different from pure utility-scale players because it sells renewable power directly to corporate customers through customized long-term contracts.
The company has built a strong operating platform with 2.80 GW of operational capacity as of October 31, 2025 and a large future pipeline. Its repeat customer contribution and long PPA tenure give visibility to revenue, while its asset-light service segment provides strategic support to the main power sales business.
Growth View
The future growth story depends on execution of contracted and advanced-stage capacity. Contracted yet-to-be-executed capacity of 3.17 GW as of October 31, 2025 is meaningful. If projects are commissioned on time and achieve expected plant availability and tariffs, the company’s revenue and EBITDA base can expand significantly.
The movement towards hybrid and CTU-connected projects can increase the company’s addressable market and improve the quality of renewable power supply offered to large customers. This is important for data centres, AI companies and multinational corporates that need more predictable renewable energy solutions.
Financial View
The company’s EBITDA base is strong, and adjusted EBITDA increased to Rs. 10,093.31 million in Fiscal 2025. However, reported PAT remains modest compared with EBITDA because of depreciation and finance costs. This is common in infrastructure-style renewable energy businesses but still requires careful investor evaluation.
Retail investors should focus on project-level returns, debt metrics, cash ROIC, cost of debt, realised tariff, PPA quality and commissioning progress. For this type of business, only looking at net profit may not give the full picture.
What Retail Investors Should Track After IPO
- How much contracted capacity gets commissioned on schedule.
- Movement in debt net of liquid assets to adjusted EBITDA.
- Whether tariffs remain stable or continue to decline.
- Customer additions and repeat order percentage.
- Execution of CTU-connected projects in Karnataka and Rajasthan.
- Cash ROIC and Cash ROE trend after new projects become operational.
- Regulatory changes affecting open access and group captive structures.
- Growth of renewable energy services and carbon services as lower capital-intensity opportunities.
