EDL partners with private firms to study battery storage  system

A new collaboration between Electricité du Laos (EDL), FoCNS Co., Ltd., and SK Corporation Co., Ltd. is set to boost Laos’ energy security. 
The three partners will conduct a feasibility study on integrating Battery Energy Storage Systems (BESS) into the national grid, a key step in creating a more stable and reliable power supply.
The aim is to improve the reliability of Laos’ power supply and ensure the grid can effectively support the country’s continued economic development.
An agreement on the study was signed by the Deputy Director General of EDL, Mr Souliya Manivong; President of FoCNS Co., Ltd., Mr Litthikay Phoummasack; and President of SK Corporation Co., Ltd., Mr  Sengtavan Xayasen.
The study will survey the use of battery energy storage systems at industrial and commercial sites across the country.
These include locations such as factories, businesses, EV charging stations, train stations, hospitals, and airports.
The findings of the study will help to identify where BESS technology can be most effectively deployed to support growing power demands.
Secondly, the partnership will conduct a technical study on EDL’s existing power distribution system, with a specific focus on Vientiane.
The study aims to determine how battery energy storage systems can be integrated to improve the overall energy security and stability of the grid.
By storing surplus power and releasing it during peak demand, battery storage systems can help balance the load and prevent outages.
Large-scale batteries can be used to store excess electrical energy, especially from renewable sources like solar and wind power. This stored energy is then used when it is needed.
Battery energy storage systems increase the stability of the power grid and help to balance the supply and demand of electricity.
They can quickly release stored energy during periods of high demand or during power outages.
To reduce energy loss, instead of having to waste power generated during low-demand periods, a battery energy storage system can store that energy for later use, maximising energy efficiency.
Since the electricity generated by solar or wind farms is not constant, a battery energy storage system can store power generated during sunny or windy periods to ensure a continuous and reliable energy supply.
