Following WHA Group's enthusiasm in innovative energy solutions, WHAUP continues its ongoing cooperation under the Memorandum of Understanding (MOU) with the Provincial Electricity Authority (PEA) for joint development of smart energy and micro-grid system to reduce electricity cost and increase reliability within the industrial complex. The first project to reach approval phase in 2021 is the Peer-to-Peer Energy Trading system which enables direct buying and selling of solar power between industrial users within the Industrial Estate Complex. Moreover, WHA Group collaborates with PTT Public Company Limited and Sertis signing a Memorandum of Understanding on Smart Energy Platform. Under this MOU, Sertis jointly developed a platform to optimise electricity management using AI and Blockchain Technology to sell solar energy within WHA Group's industrial estates. This platform will allow transactions to be decentralized and processed automatically without being controlled by any single party, making data management and transactions more secure and transparent between each of the buildings in the industrial estates. This collaboration was selected as part of the Energy Regulatory Commission Sandbox (ERC Sandbox) program run by Energy Regulatory Commission of Thailand and Provincial Electricity Authority (PEA), under the Microgrid electricity management system. The Smart Energy Platform developed between PTT, WHAUP and Sertis will help make alternative energy management more efficient and will result in better energy stability. The system, once fully implemented, will pave way for at least additional 200 MW of solar power available for use within the industrial complex, enabling industrial users to save more than 100 Million Baht per year their electricity cost and achieve over 4,300,000 tons of CO2 reduction over the project life cycle.
