Bangkok T77 P2P Trading Trial

BCPG and Powerledger have jointly recognized a promising opportunity to commercialize an innovative business model centered around distributed energy generation, specifically focusing on sharing surplus generation from solar PV systems. To explore the viability of this concept, they embarked on a trial of Powerledger’s P2P energy trading platform. This trial took place at the T77 Community Soi Sukhumvit 77 in Bangkok, Thailand. The project incorporates a total of six commercial participants and one residential apartment complex in close vicinity to each other.

The main aim of this trial project was to assess the feasibility of implementing the proposed P2P trading solution to foster a sharing economy. The project optimizes the utilization of solar PV systems installed on rooftops within the community buildings in an environment with no available remuneration from the grid for surplus solar energy. The ultimate goal was to showcase the potential benefits and capabilities of the P2P energy trading platform, while simultaneously gathering valuable insights to inform and enhance future projects. By exploring this innovative approach to energy generation and distribution, BCPG and Powerledger aspire to revolutionize the energy sector, creating a more decentralized and efficient energy exchange system.

The successful deployment of the P2P energy trading platform signifies their confidence in the viability and scalability of this model. This transformative initiative not only has the potential to benefit the involved stakeholders, including the communities, but also represents a step forward in the global pursuit of sustainable and eco-friendly energy solutions.

  • Impact 1: Incentivising the installation of additional renewable energy resources through more beneficial return on investment conditions through the opportunity to sell surplus energy at higher P2P rates rather than the usual feed-in rate of zero THB/kWh.
  • Impact 2: To reduce average electricity cost by creating a sharing economy allowing to sale of excess electricity to peers within the community at rates more favorable than usual grid rates.
  • Impact 3: To maximize the involvement of residents in energy management by giving them a certain degree of control over their energy usage and energy sources as well as giving them the opportunity and encouraging them to view their electricity usage and transactions.
  • Impact 4: Increase the self-consumption of the community by balancing surplus generation with local demand thereby reducing the export to the wider grid as well as reducing the reliance on the backup grid by maximizing the usage of locally generated energy thereby increasing the self-sufficiency of the community.

The trial project’s successful deployment seeks to establish a sustainable sharing economy through P2P energy trading within the participating community. Key objectives include proving the viability of P2P energy trading between neighboring energy consumers and convincing regulators to endorse this model and recognize P2P trading as a key activity in the electricity network.

Additionally, the project aims to maximize the utilization of community-building rooftop solar PV thereby increasing self-consumption through educational campaigns aiming at a behavioral change to shift energy usage to periods of high solar generation which contributes to a more balanced low-voltage network.

The platform also aims to enable community members to sell excess electricity beyond Power Purchase Agreements (PPA) directly to each other, fostering a self-sustaining energy marketplace. Community engagement in energy management is promoted through access to customized user interfaces providing participants with insights into their energy usage and trading statistics.

Ultimately, the project aims to reduce average electricity costs for the community by offering alterative energy sources to consumers at advantageous prices. The increased benefits for prosumers aim to incentivise additional solar/DER installations gradually reducing dependence on conventional energy sources. This in turn reduces the usage of carbon-intensive grid energy, contributing to a reduction of greenhouse gas emissions.


Mr. Bundit Sapianchai, Former BCPG President and CEO:
We are developing a Smart Community where residents can live in harmony with the environment. They can generate their own electricity of which the surplus can be traded with the help of cutting-edge technology which also enables us to provide energy management service. With internet of energy, we are transforming the energy industry by making renewable energy accessible for and affordable by all under a concept “Energy for Everyone””. Link

Enhancing Solar Energy Generation:

  • Increasing the solar capacity and generation in the project enhances the financial gains for participants.
  • This strategic addition maximizes the utilization of renewable energy sources, aligning with sustainability goals.

Optimizing Solar Energy Consumption by Adding Batteries:

  • Including a battery in the project addresses excess energy challenges during periods of low demand.
  • The battery system efficiently captures surplus energy, preventing it from being fed into the grid for zero FiT.

Dynamic Trading Opportunities for End Users:

  • Empowering end users with live dynamic trading capabilities.
  • Users can individually set their buy/sell prices based on personalized energy consumption/generation estimates for the day.
  • Enhances user engagement and customization in the energy trading process.

Regulatory Support for P2P Solution:

  • Highlighting the necessity of regulatory backing for the successful commercial rollout of P2P energy trading solutions in the region.
  • Emphasizes the importance of legal and regulatory frameworks to facilitate and legitimize P2P energy transactions.

What outcomes are anticipated from the pilot?

  • Main outcomes anticipated are increased use of local renewable energy and decreased cost of electricity for participants.

What outcomes were delivered by the pilot?

  • The anticipated outcomes are delivered by the pilot with solar consumption increasing and rate reduction of P2P rate compared to grid rate of 21 %.
