ACME Solar Advances BESS Project with Phase IV Commissioning

In a major step towards strengthening India’s energy storage infrastructure, ACME Solar Holdings Limited has announced the commissioning of the fourth phase of its Battery Energy Storage System (BESS) project in Rajasthan.

The update was shared under Regulation 30 of SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, reflecting the company’s commitment to timely disclosures and transparency.

The project is being executed through its wholly owned subsidiary, ACME Sun Power Private Limited.

Key Details of the Commissioned Phase

The newly commissioned Phase IV adds:

• 33.333 MW capacity
• 160.48 MWh energy storage capacity

This is part of the larger project with a total planned capacity of:

• 300 MW power capacity
• 1409.34 MWh storage capacity

The Commercial Operation Date (COD) for this phase is set as April 03, 2026.

Total Commissioned Capacity So Far

With the commissioning of Phase IV, ACME Solar has achieved:

• 133.336 MW of power capacity
• 641.980 MWh of storage capacity

This represents a significant portion of the total planned capacity and demonstrates the company’s steady execution capabilities.

Project Location and Strategic Importance

The BESS project is located at:

• Village: Badi Sid
• Tehsil: Bap
• Districts: Phalodi and Jodhpur
• State: Rajasthan

Rajasthan is one of India’s leading states in renewable energy generation, especially solar power. The addition of energy storage infrastructure in this region is crucial for:

• Managing intermittency of solar power
• Ensuring stable electricity supply
• Supporting grid reliability

Understanding Battery Energy Storage Systems (BESS)

Battery Energy Storage Systems (BESS) are a key technology in modern power systems.

Key functions include:

• Storing excess renewable energy for later use
• Providing backup during peak demand
• Enhancing grid stability and efficiency

As renewable energy sources like solar and wind are variable, BESS ensures that power supply remains consistent and reliable.

Importance of BESS in India’s Energy Transition

India is aggressively expanding its renewable energy capacity, aiming for a cleaner and more sustainable future.

However, this transition brings challenges such as:

• Intermittent power generation
• Grid balancing issues
• Peak demand management

BESS plays a critical role in addressing these challenges, making it a core component of future energy infrastructure.

ACME Solar’s Strategic Focus on Energy Storage

ACME Solar’s investment in BESS reflects its forward-looking strategy.

Key strategic benefits:

• Diversification beyond traditional solar generation
• Entry into high-growth energy storage segment
• Alignment with India’s clean energy goals

The phased commissioning approach ensures efficient capital deployment and timely execution.

Subsidiary Role: ACME Sun Power Private Limited

The project is being developed by ACME Sun Power Private Limited, a wholly owned subsidiary of ACME Solar.

This structure allows:

• Focused execution of large-scale projects
• Better operational efficiency
• Dedicated management for renewable initiatives

Progress Through Phased Development

Large infrastructure projects like BESS are often executed in phases.

Benefits of phased commissioning:

• Gradual capacity addition
• Early revenue generation from completed phases
• Reduced execution risk

ACME Solar has been consistently updating the market on progress, with prior announcements made on:

• March 06, 2026
• March 12, 2026
• March 31, 2026

Impact on Renewable Energy Ecosystem

The commissioning of this phase contributes to:

• Enhanced grid flexibility
• Improved renewable energy integration
• Support for India’s decarbonisation goals

Such projects are essential as the country moves towards higher renewable penetration.

Investor Perspective

For investors, this development signals:

Strong Execution Track Record

Timely commissioning reflects efficient project management.

Growth in High-Potential Segment

Energy storage is expected to see significant growth in the coming years.

Long-Term Revenue Visibility

Operational assets generate stable and predictable income.

Industry Outlook for BESS

The BESS market in India is still at an early stage but is expected to grow rapidly due to:

• Government incentives and policies
• Increasing renewable capacity
• Declining battery costs

Companies investing early in this space are likely to gain competitive advantage.

Key Takeaways

• ACME Solar commissioned Phase IV of its Rajasthan BESS project
• Added 33.333 MW / 160.48 MWh capacity
• Total commissioned capacity now 133.336 MW
• Project located in Jodhpur and Phalodi, Rajasthan
• COD set for April 03, 2026
