Summary

The video highlights the challenges faced by rural communities in Phrao District, Chiang Mai, Thailand, regarding electrical stability. Surrounded by mountains, the area faces difficulties in maintaining consistent power supply, which impacts the residents' quality of life. To address this, the Provincial Electricity Authority (PEA) introduced a battery energy storage system (BESS) that can supply power during emergencies, ensuring stability. The project serves over 2,200 households, improving power reliability and supporting sustainable development. This innovative solution also reduces carbon emissions and serves as a model for improving energy security in remote areas.

Takeaways

• 📍 Phrao district is located in the northeast of Chiang Mai with a total area of about 1,148 sq km, surrounded by mountains.
• 🔌 The community requires stable electricity supply, which is crucial for their daily lives and economic development.
• ⚡ PEA has prepared 4 electricity stations to supply power to Phrao, located in Mae Rim, Chiang Dao, Mae Taeng, and Wiang Pa Pao districts.
• 🚧 Due to the remote location, electricity supply to Phrao faces challenges, especially during outages, with power often coming from over 60 km away.
• ⚙️ Automatic Voltage Regulators (AVRs) are used to maintain stable electricity during outages, but it can take time to identify and fix issues.
• 📉 From 2018 to 2021, Phrao experienced frequent power outages, even though PEA's reliability index remained within acceptable standards.
• 🔋 To address this, PEA studied the feasibility of a battery energy storage system (BESS) to provide emergency power to Phrao for over 2 hours during outages.
• 💡 The BESS, with a capacity of 4 MWh, is the fastest solution to mitigate the impact of power outages for the local community.
• 📊 The system includes real-time monitoring and control capabilities, allowing PEA to manage power supply remotely from Chiang Mai.
• 🌍 The BESS system also helps reduce CO2 emissions by supporting cleaner energy solutions and promoting sustainability in rural areas.
