The CMU P2P trading project is part of the smart campus platform developed by the Thai Digital Energy Development (TDED) and Chiang Mai University (CMU), in collaboration with several smart grid service providers such as BCPG and Powerledger. This initiative supports CMU’s reputation as a pioneering ‘green’ institution by propelling its carbon neutrality goals. BCPG, CMU, TDED, PEA and Powerledger embraced this opportunity and created a project that realized the trading of solar energy generated across 150 university buildings with rooftop solar, through a blockchain-based P2P energy trading platform. This helps create a ‘circular economy’ within the university ecosystem by utilizing all solar PV generation on-site. Additionally, the project aims to facilitate the transition of a specific CMU building to operate with net zero greenhouse gas emissions and showcase a business model contribution to the digital utility strategy of the Provincial Electrical Authority (PEA).
The trading community comprises all three CMU campuses, with two being co-located and the third situated 5.7 km away. The trading platform enables the transfer of surplus energy between all university buildings. The project aims to demonstrate the dynamics and benefits of a P2P sharing community within a diverse community such as a university complex.
An additional objective was to demonstrate the advantages and capabilities of the P2P energy trading platform, while also collecting important insights to improve future initiatives. Through this novel approach to energy management, BCPG, CMU and Powerledger seek to transform the energy industry into a more decentralized and efficient system for exchanging energy.

The project aims to create an automated P2P trading community where all participants benefit from engaging with their peers. The overarching goal is the demonstration of P2P energy trading across participants who belong to one entity but have unique energy-related requirements and together maximize the utilization of DER installations of the prosumers in the project. The project evaluates the specific needs of all participants and provides real-time optimization of energy usage across the campus.
In addition, the platform enhances engagement by presenting load and generation profiles along with trading data through user-friendly interfaces, aiming to motivate participant involvement and fostering a closely connected energy community that satisfies its energy needs from the bottom up rather than relying fully on the backup grid and fossil-dominated electricity.
By leveraging surplus energy among peers and utilizing intuitive interfaces, the platform aims to increase renewable energy awareness and encourage a more interconnected energy community with an agreed allocation of renewable energy between faculties and buildings and real-time tracking.
Altogether, the main objectives include replacing expensive grid electricity with alternative energy sources based on renewables and increasing the self-sufficiency of the community with local energy to a maximum extent. The project’s success hinges on creating a comprehensive digital platform that efficiently oversees and analyzes both the energy exchanges and the financial transactions associated with energy generation and consumption within the CMU smart campus.
Mr. Bundit Sapianchai, Former BCPG President and CEO:
“Our project is about exploring what’s possible. It’s a microcosm of how the city will operate with clean distributed energy”. Link
Understanding of the on-site setup: Having better documentation, to understand how the on-site configuration was set up, particularly the positioning of meters and their connection to the grid.
Software configuration and interfaces between systems: The issues related to readings transfer and accuracy of readings revealed that the interoperability of systems and functioning of all related infrastructure has to be determined ahead of project implementation to avoid multiple rounds of readings transfer and solution design.
Generally, the project is still in an early stage of live trading, the full impact will be investigated at a later stage but some high level contributions have been analyzed.
What outcomes are anticipated from the pilot? The main outcome anticipated is a contribution to CMU’s transition to a smart campus utilizing a maximum of locally generated renewable energy.
