Blockchain E-Grid

For an Australian-based company in the energy sector, we developed a blockchain-based peer to peer energy trading platform to enable automated digital trading of surplus renewable energy possible among small-scale producers without third-party involvement.


Our client was an Australian-based company in the energy sector.  The client wanted to build an online P2P platform that facilitates an end-to-end unique solution for the easy exchange of energy without the involvement of intermediaries.


The legacy system of one-way power flow from large power stations to consumers on the distribution grid is undergoing a transformation. Today's consumer has the ability to generate electricity via various methods such as rooftop solar panels and home wind turbines. Residential and commercial utility customers, once simply consumers of electricity, are using these distributed energy resources in vast numbers. They are becoming producers themselves in a new, increasingly decentralized power system. At the same time, they offer an opportunity: the flexibility of these new distributed energy resources, their low carbon footprint, and their proximity to consumer loads could lead to a reduction in electricity usage and infrastructure costs. It allows the power sector to meet ambitious targets if these new small-scale energy producers can sell their excess energy. However, these new small-scale energy producers need a market system without the involvement of third-party agencies.


Our client put forward the business requirements to build a fully automated digital trading platform where consumers can trade the excess renewable energy generated while completely bypassing the involvement of third-party agencies.


Blockchain technology which allows a network of parties to securely transact with each other, without requiring any third party to facilitate trust between can be used to create a P2P E-grid. Blockchain E-Grid project integrates a meter reading function which stores data from a user’s meter directly onto the Blockchain with the help of IoT devices and sensors. The trading platform issues tokens to the producers as the energy are delivered. All the transaction details are saved on the Blockchain as well. When smaller producers of renewable energy generate surplus energy, that is shared back with the grid. Smaller producers can be anyone with solar panels on their rooftops or home wind turbines.
Once a transaction gets accomplished, a smart contract is created and a token is issued. It is then sent to the seller’s account. Details of the transaction along with other information such as seller-buyer information, amount of energy sold, etc are registered on to the entire network as a tamper-proof certificate. The Platform also offers an option for selecting buyers and producers.


Blockchain-based P2P E-grid is achieved through an automatic digital trading process made possible by Ethereum smart contracts on a permissioned blockchain using Monax/Quorum. IoT sensors attached to the energy meters track the quantity of energy produced, distributed outwards, etc, and records the information as transaction ledgers. 

  • Smart contract-based energy trading
  • Permissioned blockchain network
  • Automated digital trading
  • No Wastage of Electricity
  • Less dependency on the national grid

The Blockchain P2P E-Grid allows for a more efficient and highly transparent trading system. The platform allows small energy producers to sell surplus energy to each other instead of selling it to the main grid. The platform completely avoids the rigorous involvement of third-party agencies. Since no third-party is involved, the high transaction costs associated with the buying, selling, and verification of the certificates can be fully eliminated.

Frequently Asked Questions

What are the benefits of peer to peer energy trading?

Peer to peer energy trading offers several distinctive benefits:

  • Decentralization: Peer to peer energy trading allows for direct energy exchange between consumers and producers, eliminating the need for intermediaries. This decentralized approach empowers individuals and promotes community engagement in the energy market.
  • Cost Efficiency: By removing intermediaries, P2P trading reduces transaction costs associated with energy exchange. Participants can negotiate prices directly, leading to competitive pricing and lowering consumer energy costs.
  • Renewable Energy Integration: P2P trading facilitates the integration of localized renewable energy sources into the grid. Prosumers can sell excess energy generated from renewables, incentivizing the adoption of clean energy technologies and supporting a more sustainable energy mix.
  • Energy Resilience: P2P trading enables the formation of microgrids, which operate independently from the main grid during disruptions or emergencies. Also, this enhances energy resilience, as communities can maintain power supply and mitigate the impact of outages.
  • Grid Stability: By balancing energy supply and demand locally, P2P trading reduces strain on the main grid. In addition, this helps to stabilize the grid and minimize transmission losses, improving overall system efficiency.
  • Empowerment and Engagement: P2P energy trading empowers individuals to actively participate in the energy market and have greater control over their energy choices. It promotes energy literacy, awareness, and engagement within communities.
  • Environmental Sustainability: P2P trading encourages localized renewable energy sources, reducing reliance on fossil fuels and decreasing greenhouse gas emissions. It supports the transition to a cleaner and more sustainable energy future.
  • Innovation and Technological Advancement: P2P energy trading drives innovation in energy technologies and business models. It encourages the development of smart grids, advanced metering systems, and digital platforms that facilitate efficient energy trading.
  • Economic Opportunities: P2P trading creates economic opportunities for prosumers, allowing them to monetize their excess energy production. Moreover, this can stimulate local economic development and job creation in renewable energy sectors.
  • Energy Independence: P2P trading promotes energy self-sufficiency by enabling localized energy generation and consumption. It reduces dependency on centralized power plants and fosters a more resilient and independent energy system.
