Stars

Utility scale solar expansion drives growth

ReNew Energy Global maintains a dominant 12% market share in the Indian utility solar sector as of December 2025. The national market growth rate for utility-scale solar is 24% annually, sustaining the high-growth status of this unit. For the 2025 fiscal period, solar operations reported an EBITDA margin of 83%. Total capital expenditure allocated to new solar installations in 2025 was $1.4 billion to support a 10 GW operational capacity. Long-term power purchase agreements (PPAs) underpin project economics, producing an approximate return on investment (ROI) of 15% for these utility projects.

Hybrid and round the clock projects

The hybrid wind-solar segment is a high-growth star with market expansion exceeding 30% in 2025. ReNew secured a 15% share of hybrid auction capacity awarded by the Solar Energy Corporation of India (SECI). These hybrid+storage projects command higher effective tariffs and contributed 18% to total company revenue in 2025. CAPEX for energy-storage-integrated hybrid projects rose to $800 million in 2025 to meet peak demand and provide firming capacity. The segment achieves an internal rate of return (IRR) of approximately 14% and delivers ancillary grid services, including frequency response.

Commercial and industrial energy solutions

The corporate power purchase agreement (CPPA) segment has evolved into a star with a 10% share of the private energy market. Demand grew by 20% in 2025 as corporates accelerated net-zero commitments. Revenue from CPPAs reached 15% of group total in 2025 with margins around 75%. ReNew invested $400 million during 2025 to expand distributed solar and wind capacity for industrial and commercial clients. Shorter project gestation and higher effective ROI make this unit an attractive, fast-scaling contributor to cash flow and earnings.

• Stars collectively drive rapid capacity build and revenue diversification: CAPEX total ~ $2.6 billion in 2025 across these segments.
• High-margin operations: weighted-average EBITDA margin across stars exceeds 75% driven by utility solar and CPPA margins.
• Strong cash visibility from long-term PPAs and higher tariff hybrids supports sustained investment and deleveraging potential.
• Balanced risk profile: utility projects offer scale and predictability (15% ROI), hybrids provide premium returns plus ancillary revenue (IRR ~14%), CPPAs deliver faster payback and higher margin.

ReNew Energy Global Plc (RNW) - BCG Matrix Analysis: Cash Cows

Mature wind energy portfolio performance: The established onshore wind energy segment operates as a primary cash cow for ReNew, delivering stable free cash flow from a 4.5 GW operational capacity. These assets account for an approximate 14% share of the Indian wind market and generate roughly $450 million in annual free cash flow. Market expansion for onshore wind has slowed, with current annual market growth near 7%. Operating margins on these mature turbines remain high at 76% despite asset age and accelerated component replacement cycles in some sites. ReNew directs approximately $150 million per year in maintenance CAPEX to this segment, prioritizing reliability and debt servicing. The wind portfolio contributes a steady and predictable revenue stream used to service project-level and corporate debt and to fund selective growth capex.

Legacy utility solar installations: Solar projects commissioned prior to 2021 constitute another significant cash cow. Approximately 95% of this legacy solar capacity is under long-term (25-year) power purchase agreements (PPAs), creating revenue visibility and low merchant exposure. These legacy blocks represent about 8% of the installed base market share in their operating regions and contribute roughly 22% of ReNew's consolidated annual revenue. EBITDA margins for these assets have stabilized at approximately 80% due to standardized O&M routines and fixed-term supply and service contracts. Management oversight requirements are minimal, with operations centralized and performance monitoring automated, enabling these assets to finance higher-risk technology investments and pipeline development.

Hydroelectric power generation assets: Hydroelectric assets acquired in prior years have matured into a complementary cash cow, providing base load capacity and portfolio diversification. The hydro segment contributes about 5% of total group revenue and operates in a low-growth market with approximately 4% annual expansion. ReNew's private hydro market share is near 3%, with EBITDA margins reaching ~85% owing to long asset life, low variable costs, and stable dispatch profiles. Annual sustaining CAPEX for hydro is modest-about $50 million-covering civil maintenance, turbine overhauls and environmental compliance. These projects deliver a portfolio-level ROI of ~16%, supplying liquidity for investments in emerging technologies and project-scale green hydrogen pilots.

Key operational and financial characteristics of cash cow segments:

• Predictable cash flow: $450m from wind + stable contributions from solar and hydro underpin liquidity.
• High operating leverage: EBITDA margins of 76-85% across segments reduce marginal cost volatility.
• Low sustaining CAPEX intensity: Combined sustaining CAPEX ~ $200m annually (wind $150m + hydro $50m; legacy solar minimal).
• Debt servicing focus: Cash cows prioritized for project-level and corporate interest and amortization obligations.
• Contractual stability: ~95% of legacy solar capacity under 25-year PPAs lowers merchant exposure and revenue volatility.

ReNew Energy Global Plc (RNW) - BCG Matrix Analysis: Question Marks

Dogs - Question Marks

Green hydrogen and ammonia ventures

The green hydrogen segment is a high-growth question mark: the Indian market is projected to grow at 40% CAGR. ReNew has committed $500,000,000 in initial CAPEX for pilot plants but currently holds less than 2% of the emerging domestic and regional market. Revenue contribution from this business unit is currently under 1% of total group turnover as of December 2025. Target unit economics require achieving production costs near $2.00/kg H2; current estimated levelized cost of hydrogen for ReNew pilot projects is approximately $4.50-$6.00/kg based on electrolyzer CAPEX, renewable power PPA rates, and capacity factors. Key dependencies include government subsidy frameworks (capital grants, production-linked incentives), electrolyzer supply chain scale-up, and global export demand for green ammonia and hydrogen.

Battery energy storage systems expansion

Standalone battery energy storage systems (BESS) represent a high-growth question mark with market expansion estimated near 50% CAGR within the energy transition sector. ReNew currently operates a ~500 MWh portfolio of BESS projects, representing roughly 3% of the estimated national storage market capacity (national market estimate: ~16,700 MWh). The segment required initial CAPEX of approximately $300,000,000 to build the current lithium-ion infrastructure, which compresses short-term return on equity and extends payback periods beyond typical 5-7 year targets. Present contribution to consolidated EBITDA from BESS is under 5%. Profitability hinges on continued decline in cell costs (current cell pack costs assumed $150-$200/kWh versus target <$100/kWh), development of time-of-day and ancillary services pricing, and revenue stacking (frequency regulation, capacity markets, arbitrage).

Carbon credit and trading desk

The carbon offset and trading desk is a question mark operating in a market expanding at ~35% annually. ReNew's dedicated trading desk captures approximately 4% of the voluntary carbon market share in Asia and contributes about 2% to total consolidated revenue. This business requires relatively low CAPEX versus generation assets (estimated initial working capital and systems investment $5-$15 million) but exhibits volatile margins and earnings. Current reported margin sits near 40% gross on traded credits, driven by brokerage spreads and origination income, yet regulatory uncertainty in international carbon markets creates price and demand volatility. Scaling this segment will require stronger integration with the company's renewable energy certificate (REC) generation and long-term offtake or forward-selling strategies.

Risks and critical success factors

• Policy risk: dependency on subsidies, PLI schemes, and export incentives for green fuels and storage revenue frameworks.
• Technology and cost curve risk: need for rapid declines in electrolyzer and battery cell costs to reach target LCOH and storage ROI.
• Market demand risk: global export demand for green hydrogen/ammonia and liquidity in carbon markets.
• Capital intensity and financing: large upfront CAPEX ($800M+ across hydrogen and BESS) requires access to concessional financing or project-level partners to avoid equity dilution.
• Operational integration: ability to integrate BESS and carbon trading with existing renewables generation to optimize revenue stacking.

Near-term value levers

• Secure government PPA/production incentives and long-term offtake agreements for green hydrogen/ammonia.
• Negotiate battery cell supply contracts to capture declining cost curves and enable faster project breakeven.
• Scale carbon desk via bundled REC + carbon product offerings and strategic partnerships to increase market share above 10% in target geographies.
• Deploy pilot projects with strict unit-economics monitoring to achieve targeted $2/kg H2 and sub-$100/kWh battery pack cost thresholds.

ReNew Energy Global Plc (RNW) - BCG Matrix Analysis: Dogs

Dogs - Legacy small scale wind turbines

The portfolio of older sub-megawatt wind turbines represents a dog segment with a relative market share below 1% and negative market growth as utility-scale and multi-megawatt onshore machines displace small units. These assets deliver constrained generation and increasing per-MW O&M intensity. Measured metrics for the legacy fleet are summarized below.

Operational and financial implications for this dog segment include:

• Margin compression: Rising maintenance (15% of asset revenue) and lower load factors reduce contribution to consolidated EBITDA.
• Limited strategic upside: Market share <1% and negative growth limit organic recovery prospects.
• Capital deployment trade-off: Further CAPEX yields low IRR versus repowering or exit options.
• Regulatory and salvage considerations: Decommissioning carries environmental and permitting costs that must be modelled.

Recommended near-term actions being evaluated by management:

• Selective repowering of sites with suitable grid access and land rights - target IRR threshold ≥10%.
• Decommissioning low-yield turbines with salvage and remediation cost estimates built into cash flow models.
• Reallocate maintenance budgets to higher-return assets to protect group-level margins.

Dogs - Non-core digital energy services

Third-party digital monitoring and energy management services (software-focused) have failed to gain traction, generating a market share below 2% in a crowded SME service market. Segment growth for independent providers is low (~5% p.a.), and revenue contribution to ReNew is negligible, at <0.5% of total group turnover. Financial performance metrics are shown below.

Key challenges faced by the non-core digital services dog:

• Scale disadvantage versus pure-play SaaS providers leading to higher marginal customer acquisition cost.
• Persistent negative ROI relative to ReNew's weighted average cost of capital.
• Low revenue diversification benefit given <0.5% group contribution.
• Market positioning mismatch - limited IP and product differentiation.

Strategic options under consideration:

• Divestiture or carve-out to a specialist buyer to recover invested capital and stop ongoing losses.
• License or partnership model with third-party platforms to capture residual revenue with minimal CAPEX.
• Winding down operations if exit or partnership opportunities are non-viable, reallocating staff to core asset operations.
