The Background

As the largest solar plant in Southeast Asia, this project represents a pivotal step for Thailand in its transition to a low-carbon society. However, it first had to overcome several significant challenges.

The Challenges

Keeping Power Stable, Even When the Sun Isn’t Shining

Because solar power can be unpredictable, Sungrow utilized advanced storage technology to capture excess energy, ensuring power is available whenever it’s needed—rain or shine.

Efficiently Managing Both ESS and PV Systems

Coordinating solar and storage systems can be complex. Sungrow’s smart management technology ensures every watt of solar power is effectively utilized, optimizing overall performance.

Maintaining System Safety and Longevity

High-capacity storage systems are vulnerable to overheating, but Sungrow’s liquid cooling and strict ESS safety protocols ensure the system runs smoother and lasts longer.

The Solution

The solution’s photovoltaic (PV) system has an installed capacity of 48.91 MWp and utilizes 196 inverters. Complementing the solar array is a powerful energy storage system (ESS) comprised of nine individual units. In total, the ESS provides 45 MW of power and 136 MWh of capacity. Each ESS unit is a fully integrated solution containing one SC5000UD Power Conversion System (PCS), a 15,138 kWh Lithium Iron Phosphate (LFP) battery, and a liquid cooling system. The units also include a fire protection system and other auxiliary equipment to ensure safe and reliable operation.

The Impacts

Powering the Land of a Thousand Smiles Completed and connected to the grid on January 20, 2023, the 48.91 MWp solar plant in Sa Kaeo is paired with a 45 MW / 136 MWh energy storage system. The project aligns with Thailand’s national strategy and Power Development Plan (PDP 2018-2037), which sets a goal for renewable energy to supply 37% of the country's total power by 2037.
