Spectral And Alliander Launch Blockchain-based Renewable Energy Sharing Token


Spectral and Alliander have launched a new Blockchain-based energy sharing token at De Ceuvel  – a city playground for innovation and creativity in Amsterdam. Named the ‘Jouliette’, the new token aims to empower individuals and communities to easily manage and share their locally produced renewable energy.

Philip Gladek, CEO, Spectral, said:

“The Jouliette and its associated broader applications represents an important step forward towards realizing a local, circular, resource-based economy. We’re excited to launch it at De Ceuvel, which has become a globally visible showcase for sustainable urban development and a hub for cleantech innovation. In the coming months, the De Ceuvel community will be experimenting with the Jouliette in practice, and engaging in a number of user experience design sessions to take the platform to the next level, together with the system developers. We are looking forward to taking this idea forward and helping it scale up across the wider Buiksloterham community and beyond, to realise its full potential.”

The Jouliette – named after the Joule unit of measurement for energy – is the first such initiative of its kind in the Netherlands. The project aims to become a landmark example of how to harness the capabilities of Blockchain technology to create greater social value and to support a bottom-up transition towards a more distributed, robust, and transparent economy, underpinned by 100% renewable energy.

Currently, the energy market works in such a way that energy suppliers receive data from a (smart) meter, a bill is issued to the customer, and then the bill is paid via a monetary transaction from one bank to another. With the Jouliette token, the De Ceuvel community members are able to make secure (peer- to- peer) transactions directly between their own virtual currency ‘wallets’. Blockchain, the technology behind Bitcoin, ensures that these transactions are secure and decentralized, with the history of all transactions being shared with all the community members, so they can be (automatically) verified without needing the intervention of a “trusted” bank.

What makes this unique ecosystem possible at De Ceuvel is the fact that the site features a private (renewable energy-based) smart-grid. This enables the community to exchange renewable energy (independent of the national electricity grid) produced by their photovoltaic (PV) panels, without any restrictions, and therefore avoid existing market barriers. With the Jouliette platform, the De Ceuvel community can easily manage their own micro-economy, and unlike purely speculative currencies, the Jouliette tokens are backed up by physical energy production. Beyond just enabling energy exchange, the community will be exploring further applications for the Jouliette, such as using it to trade for goods at the De Ceuvel Cafe, to facilitate a local time-banking system, and to integrate other intra-community services, such as a car-sharing program.

The Jouliette platform was developed by Spectral, a smart energy services company (and spin-off of sustainability consultancy, Metabolic), in collaboration with Alliander, one of the Netherland’s largest distribution system operators and creator of the Jouliette concept. Besides the peer-to-peer Blockchain trading system, the Jouliette platform is equipped with a number of additional features, such as a real-time power-flow map of the community, high-resolution data visualizations, and machine-learning forecasting systems, which provide users with greater insights into their (real-time) energy use and projected production / consumption. You can see it live on the Jouliette website.

Pallas Agterberg, Strategy Director, Alliander, said:

“In general society looks at big solutions when it comes to the transition towards a renewable energy system, like underground CO2 storage and big offshore wind farms. That makes the energy transition intangible, expensive and out of reach for many people. We want a cost neutral acceleration in the renewable transition, and perhaps even one with a cost reduction. But then we need a decentralized model which facilitates greater local interaction and incentivizes direct peer to peer exchange of renewable energy. We look forward to exploring how concepts like the Jouliette can help lead the transition we need to see.”
