ACME Solar is emerging as a compelling growth story in India’s renewable energy landscape, with Motilal Oswal Financial Services maintaining a BUY recommendation and assigning a target price of Rs 341, implying a 34% upside from the current market price of Rs 256. The investment thesis is anchored in robust earnings visibility backed by long-term power purchase agreements (PPAs), a rapidly expanding operational portfolio, and a potentially transformative entry into battery energy storage systems (BESS). With capacity set to more than double over the next three years and EBITDA expected to grow at an aggressive pace, ACME Solar is positioning itself as a structurally advantaged player in the evolving clean energy ecosystem.

Portfolio Strength Provides Earnings Visibility and Stability

ACME Solar’s current portfolio stands at 8.1GW, offering a rare blend of scale and predictability. Of this, nearly 78% is already backed by PPAs, ensuring steady cash flows and insulating the company from merchant price volatility.

The company’s operational capacity of approximately 3GW is expected to expand to 5.5GW by FY28, driven by the commissioning of its 5.1GW under-construction pipeline. Importantly, only ~1.8GW remains without PPAs, and most of this untied capacity comprises hybrid and FDRE (Firm and Dispatchable Renewable Energy) projects—segments that are witnessing rising demand.

This structural visibility significantly reduces execution risk and enhances investor confidence in future earnings streams.

Capacity Expansion to Drive Multi-Year Earnings Acceleration

The company is entering a high-growth phase with EBITDA and profit expected to surge sharply. According to projections:

EBITDA is expected to grow at a CAGR of ~74% between FY25 and FY28

Adjusted PAT is projected to expand at ~76% CAGR

Revenue is forecast to scale from Rs 20.9 billion in FY26E to Rs 73.0 billion by FY28E

Margins are expected to remain resilient, improving marginally to ~88.9% EBITDA margin by FY28, supported by a shift toward higher-yield FDRE and hybrid projects.

This combination of volume expansion and margin stability creates a powerful earnings compounding trajectory.

Battery Storage (BESS) Strategy Could Unlock Hidden Value

The most significant upside trigger lies in ACME’s aggressive push into battery storage.

The company has outlined a ~16GWh BESS pipeline, including:

550MWh of standalone projects

~15.5GWh integrated with FDRE projects

Near-term execution targets include:

~2GWh commissioning in 4QFY26

Another ~2GWh in 1QFY27

~10GWh cumulative capacity by CY27

Notably, this upside is not yet factored into current estimates, making it a potential earnings surprise. Management has guided for ~Rs 1.7 billion EBITDA per GWh, assuming arbitrage economics of Rs 5 per unit.

This positions ACME Solar at the intersection of renewable generation and energy storage, a critical future growth vector.

Execution Strength Backed by Transmission Readiness

Execution risks—often a bottleneck in infrastructure projects—appear well managed.

ACME has:

Secured transmission connectivity for almost its entire 5.1GW under-construction capacity

Built a 7.5GW connectivity pipeline (1.3GW secured, 6.2GW applied)

This provides a significant competitive advantage in bidding for new projects, especially in an environment where transmission constraints have slowed industry-wide capacity additions.

Additionally, regulatory improvements in Right-of-Way (RoW) policies are expected to ease transmission delays going forward.

Industry Tailwinds Favor Complex Renewable Solutions

The renewable energy landscape is undergoing a structural shift.

States are increasingly favoring:

FDRE projects

Round-the-clock (RTC) renewable solutions

These formats demand:

Integrated storage

Hybrid configurations

Higher capital intensity

This trend raises entry barriers, limiting competition from smaller developers and benefiting scaled players like ACME Solar.

Furthermore, with over 40GW of awarded projects awaiting PPA finalization, the clearing of this backlog could trigger a fresh cycle of bidding activity, accelerating sector growth.

Detailed Valuation Framework and Target Price

Motilal Oswal values ACME Solar using an EV/EBITDA methodology, assigning a 9.5x multiple to FY28E EBITDA.

Below is the valuation snapshot:

The valuation reflects both earnings growth visibility and optional upside from storage deployment.

Balance Sheet Leverage and Capital Intensity Remain Key Watchpoints

While growth prospects are strong, leverage levels remain elevated.

Net Debt/Equity is projected at 5.8x in FY28E

Net Debt/EBITDA expected to moderate to 6.3x

The capital-intensive nature of renewable infrastructure, particularly with BESS integration, will require disciplined capital allocation and refinancing strategies.

However, improving cash flows and asset monetization opportunities could gradually strengthen the balance sheet.

Investment View: Structural Growth Story with Optionality

ACME Solar offers a rare combination of visibility, scalability, and embedded optionality.

Key investment drivers:

Strong PPA-backed revenue base

Aggressive capacity expansion

Industry shift toward hybrid and dispatchable renewable energy

Significant upside from BESS integration

At current valuations, the stock offers a favorable risk-reward profile, particularly for investors seeking exposure to India’s long-term clean energy transition.

Key Investment Levels for Investors

Current Market Price: Rs 256
Target Price: Rs 341
Upside Potential: 34%

Recommended Strategy:

Accumulate on dips for medium- to long-term horizon

Monitor execution of BESS rollout as a key catalyst

Final Word

ACME Solar is no longer just a renewable energy generator—it is evolving into a future-ready integrated energy platform. With earnings set to inflect sharply and strategic positioning in storage-led energy solutions, the company stands at the forefront of India’s next phase of energy transition.
