Ethereum-based Electricity Trading Platform
Sector: Tertiary sector · Industry: Public infrastructure and utilities · Organisation: Grid+ · Maturity level: Pilot
Grid+ is developing an Ethereum-based platform that enables direct electricity trading between consumers and renewable energy producers. The company plans to introduce a specialized device in Texas that automatically handles electricity buying and selling through smart contracts. This decentralized solution aims to eliminate intermediaries and provide both private consumers and photovoltaic system owners with direct access to the energy market.

Description
STROMDAO GmbH (Offenburg) operates Corrently — a blockchain-based energy platform for decentralized electricity trading. The company is registered as an authorised energy supplier in Germany and connects green electricity producers (PV systems, wind farms) directly with end consumers in the region.
The classic energy system is centralised: electricity is generated by power plants, transported through grids and distributed by energy suppliers. Renewable energy fits poorly into this model: PV systems and wind farms are decentralised, volatile and regionally diverse. Corrently solves this with blockchain: producers register their system on the platform; consumers choose preferred producers in their region; smart contracts automatically manage the balance between feed-in and consumption and create minute-accurate billing. The Corrently book Flexibilisation of Electricity Supply 2025 describes blockchain-based decentralized trading platforms as one of the keys to the energy transition. Blockchain Welt analysed Corrently as a model for the future of decentralized supply networks. The mandatory Smart Meter Gateway from 2025 in Germany creates the infrastructure for real-time blockchain billing.
Perspectives
B2B — organisations perspective
Operators of PV systems and wind farms can sell their electricity directly to regional consumers via Corrently — higher revenues through direct trading, automatic smart contract billing without sales costs.
B2C — consumers perspective
Households can buy verifiably green electricity from their region via Corrently — directly from the producer, transparently on the blockchain, without energy policy detours through traditional suppliers.
Employees perspective
Employees in the energy industry need to familiarise themselves with new technologies such as blockchain and smart contracts to remain relevant in the changing sector. Technical experts are increasingly required for the integration and maintenance of blockchain-based energy systems.
Benefits
General
- Elimination of intermediaries in energy trading can lead to lower costs for end consumers.
- Promotion of renewable energy use through direct financial incentives for decentralized electricity generation.
- Increased transparency and control over energy consumption and costs through blockchain technology.
B2B — organisations
- New business models as platform providers for decentralized energy trading instead of traditional energy supply.
B2C — consumers
- Potential cost savings through direct energy trading without intermediaries.
- Opportunity for photovoltaic system owners to generate additional income through electricity sales.
Employees
- New career opportunities in the growing blockchain and smart grid industry.
Challenges
General
- Challenge of scaling pilot projects to mass market level.
- Complex integration into existing energy infrastructure and smart meter systems.
B2B — organisations
- Regulatory uncertainties and compliance requirements for decentralized energy trading.
Employees
- Need for further training in blockchain technologies and new energy trading systems.
Technology foundation
Grid+ uses the Ethereum blockchain as the technical foundation for automated electricity trading contracts between producers and consumers. The Ethereum platform is particularly suitable for this use case as it enables programmable smart contracts that can execute complex trading rules and automatic billing without human intervention.
Implementation examples
Grid+ Texas pilot
The company aims to eliminate inefficiencies in the traditional energy market by removing intermediaries. The goal is to provide consumers with direct access to the energy market while offering renewable energy producers better marketing opportunities.
Grid+ is developing an Ethereum-based device for automatic electricity trading in Texas.
Grid+ plans to launch a special Ethereum-based device in Texas that enables automatic buying and selling of electricity. The device acts as an interface between the local power grid and the Ethereum blockchain and executes trading activities via smart contracts. The solution targets both electricity consumers and owners of photovoltaic systems who want to market their surplus electricity directly.
Grid+ addresses the problem of high energy costs caused by intermediaries and the lack of direct market access for small energy producers. The system is also intended to reduce the complexity of traditional energy billing through automated smart contracts.
