As the world pushes towards Net Zero, clean energy sources like solar and wind have become critical players. However, ensuring these energy sources are “always available” and “practically usable” remains a significant challenge, given their intermittent nature. This is where ESS (Energy Storage Systems) comes in, serving as the backbone of modern clean energy infrastructure. ESS stores excess energy for later use, ensuring a stable and continuous power supply for everything from large power grids to factories, commercial buildings, and industrial estates. At the same time, the rise of electric vehicles (EVs) is adding further pressure on power grids to become more flexible and resilient. Battery-based ESS solutions play a critical role in bridging the gap between “clean energy” and “next-generation mobility”, supporting not just everyday EV usage but also the long-term growth of a sustainable EV ecosystem.

Understanding Energy Storage Systems (ESS)

Energy Storage Systems (ESS) are technologies that store electrical energy for use when needed, acting as a critical enabler for efficient renewable energy usage and smart energy management in the Net Zero era. ESS technologies vary widely depending on their application, but they generally fall into two main categories:

1. Stationary ESS – Permanent Energy Storage Systems

These systems are designed for permanent installation in locations like factories, commercial buildings, power grids, and industrial estates. Their primary functions include:

• Storing energy during periods of low electricity rates for use when prices peak
• Smoothing out power supply during high demand periods (peak load)
• Reducing overall energy costs and enhancing grid stability

 2. Mobile ESS or EV Battery – Energy Storage for Electric Vehicles

EV batteries are a type of mobile ESS, designed for use in electric vehicles, ranging from personal passenger cars to heavy-duty commercial trucks.

Key challenges for EV batteries include achieving a balance of lightweight design, high energy density, fast charging, and safety, making them suitable for long-range travel and various real-world road conditions.

Banpu NEXT’s Expertise in Comprehensive ESS Solutions

As a leading provider of Net Zero Solutions in the Asia-Pacific region, Banpu NEXT is deeply invested in large-scale Battery Energy Storage Systems (BESS) to enhance the efficiency and stability of renewable energy. These systems are designed to seamlessly connect with power grids, support energy trading, and enable a more reliable transition to clean energy at all levels.

Strengthening Regional Energy Infrastructure with BESS

Banpu NEXT has made significant investments in large-scale BESS projects overseas to enhance grid stability and support renewable energy integration. These projects are helping to balance power loads and ensure reliable electricity supply, even as the share of renewable energy increases.

Some of the key BESS projects include:

• Solar Hybrid Projects in Indonesia – Providing stable, clean energy for remote communities and industrial zones.
• Large Battery Farms in Japan – Currently under development at Iwate Tono, Aizu, and Tsuno, with plans for commercial operation (COD) in Q2 2025, Q1 2028, and Q2 2028 respectively.

These projects showcase the potential for creating stable, flexible, and sustainable clean energy systems across the region, serving as a model for potential BESS projects in Thailand, should opportunities arise in the future.

Supporting the EV Ecosystem from Upstream to Battery Recycling

Banpu NEXT is also expanding its role in the EV battery sector through strategic partnerships across the value chain, including:

• Joint Venture with Durapower – Operating battery manufacturing plants in China and establishing DP NEXT in Thailand to assemble high-capacity EV batteries for commercial vehicles.
• Partnership with SVOLT Thailand – Setting up battery production for personal electric vehicles to meet the rapidly growing EV market demand.
• Investment in Green Li-ion – Developing advanced battery recycling technologies to reduce waste and create a sustainable closed-loop battery lifecycle.

From grid-level investments to EV battery development and recycling, Banpu NEXT demonstrates its readiness in technology, infrastructure, and long-term vision to drive fully integrated energy storage systems. This approach connects every stage of the energy value chain, from upstream to downstream, turning the vision of a sustainable, interconnected energy future into reality at all levels.
