Tokenising Estonia’s Energy Grid: 1st Results of Groundbreaking Blockchain Project
WePower announces the successful delivery of a landmark nationwide energy tokenization pilot project in Estonia in partnership with transmission system operator (TSO) Elering – paving the way for the digital revolution of the energy sector.
The initiative, to convert energy consumption and production data onto the blockchain on a national scale, has been part of a groundbreaking collaboration between the two organisations – with the results proving positive for both energy and blockchain industries.
Kaspar Karleep, CTO of WePower, says: “Projects of this scale and ambition haven’t been attempted before, in part because of the complexity involved, but also because energy data is highly sensitive. Blockchain is the ideal enabler because its foundational principle is trust, which can be leveraged to bring revolutionary transparency to the industry.”
Estonia provided the ideal infrastructure for this type of testing as the county has 100% smart meter coverage and a data sharing platform called Estfeed. Estfeed enables consumers to download and share their data with any persons or companies whom they choose, as well as anonymous and aggregated data, such as that used for WePower’s pilot.
The pilot project tested the limits of the technology, with WePower’s engineers successfully navigating their way around the challenges of uploading such a large amount of real-world data to the blockchain – proving that it was possible.
The first phase of the tokenization pilot allowed WePower to validate and verify the logic and processes that will be at the core of the WePower platform. In total, 26,000 hours and 24TWh of energy production and consumption data was uploaded to blockchain, creating a total of 39 billion Smart Energy Tokens.
One of the key findings was that Ethereum is mature enough to accomodate contracts with multi-year terms. However, while Ethereum is currently one of the most mature blockchain solutions supporting smart contracts, a fully decentralized application for large scale autonomous usage is not yet feasible for WePower’s purposes. For now, a hybrid solution will be utilised while monitoring the rapid development of Ethereum as well as other blockchain technologies.
Through testing real data, WePower has been able to build a fundamental new technology layer for the energy industry.
This new technology layer will allow for both software and hardware innovation that will bring much needed change to the way energy markets operate – especially when it comes to developing models for more effective integration of distributed green energy with the grid, enabling new interactions between different partners and breaking silos between energy market participants.
Taavi Veskimägi, CEO of Elering, the Estonian TSO which operates Estfeed, says: “Future clean and secure energy will depend on innovative solutions and consumer empowerment. However, a major barrier in most countries is lack of access to energy data. Estfeed unlocks data access within Estonia and we are now working towards doing this on an international level.”
WePower first signed a memorandum of understanding with Elering in October 2017 to convert energy data into blockchain on a national scale. It’s the first WePower research and development project that aims to validate approaches and use cases for WePower’s trading platform – which will enable consumers to purchase green energy directly from producers, with information stored on the blockchain – as well as the wider business.
To achieve WePower’s full vision, a number of different blockchains will be tested to find the best fit for large scale infrastructure projects. Experience gained from the project will also be shared to benefit other developers.
Nikolaj Martyniuk, CEO of WePower, says: “The energy and wider infrastructure sectors have been largely untouched by the digital disruption that has transformed so many other industries. Start-ups rarely tackle big infrastructure issues because of the cost and complexity involved, but our approach deploys blockchain as the critical means to change this. The successful delivery of our project with Elering shows that we can solve real-world problems at scale.”
In February 2018 WePower completed the largest ever ICO in the energy space (hitting its $40 million hard-cap with 22,933 contributors). The company’s Ethereum-based energy tokens are essentially digital self-settling power purchase contracts, which each represent one kilowatt-hour of power produced. They are tradable and can also be liquidated into the local energy wholesale market. This is achieved by linking digital contracts with power grid data on the blockchain.
WePower received the consumption data from Elering aggregated on the zip code level in order to ensure anonymity of private individuals from a GDPR perspective. The project adhered to the safety and security of supply standards that are obligatory for Transmission and Distribution System Operators.
The results of the pilot offer a huge boost to WePower, with the team now moving forward with greater certainty the impact they can achieve around the world. WePower will launch their Australian operations later this month.
