Imagine being fully in control of the energy you create and use.

What if you are able to switch friction-less from supplier to supplier, based on a smart contract with your preferences and settings (green energy, local energy, cheap energy), with a totally transparent and verifiable measurement system and your data for you to use for your and society's benefit.

New business models based on total flexibility will allow to make an instant consumer impact (I choose the most local, most green supplier at all times) and will speed up the energy transition massively.

Blockchain-based solutions could facilitate these user-central transparent big data-processing and privacy-compliance systems. Nuon/Vattenfall, Gasunie and New Energy Coalition team up to collaborate in the blockchain ecosystem and to tackle these challenges.

Introducing the challenges of the Blockchaingers Hackathon Energy Transition Track.



The General Data Protection Regulation (GDPR) is a new EU regulation (applicable and binding as of May 28th 2018) with the intent to strengthen and unify data protection for all EU residents. The GDPR aims primarily to give control back to citizens and residents over their personal data and to simplify the regulatory environment for international business by unifying regulation within the EU.

All organizations that target EU citizens must comply. GDPR builds further on the current Directive 95/46EC, but emphasizes:

The energy sector is also affected by this new regulation. This is because of the structure of mandates in the energy sector, the different responsibilities each player has in the scheme, the obligation to share data with, for example, grid operators and governments and the business-case of energy companies regarding commercial use of data.

GDPR considers 2 categories for personal data:

Normal personal data like:

Direct identifiable: name, e-mail address, photo, video recording etc.

Indirect identifiable: telephone number, zip code, identification number, username, IP address, smart meter info, bank account, etc.

Special categories of personal data [defined set]:

All personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade-union membership, data concerning health or sex life, genetic and biometric data.


Within GDPR there are 6 principals:


Because of the chain, the different players and the vast amount of data in the energy sector, there is a risk the new law leads to an even more complex situation. An energy company needs to obtain data and needs to be able to give the data back to the customer in the new situation.

The track sponsors want to solve this challenge. They want to see a prototype of a system that meets the standards of the GDPR and at the same time be able to receive and use the relevant data. They want to accelerate your solution using their power to scale.

The prototype does not only need to be functional on a technical level, but also needs to be very appealing to use for a customer, as the involvement of, for instance, home-owners with solar panels is crucial.

The track sponsors are inviting other companies to join them in this quest. Since the whole energy sector is affected, our track sponsors would like the solution to be an open source building block.

Thereby every company affected by the implementation of the GDPR is able to develop their own specific solution based upon the communal building block.


Challenge 1: GDPR & Blockchain

Can we make a simple Know Your Customers like process, where the customer knows to whom he is sending which data, with a single point of truth (open, transparent, blockchain-based) where all necessary players in the energy-market can make use of, based on customer mandate?


Challenge 2: IoT & Blockchain

How can IoT & blockchain contribute to the energy transition in order to ensure that consumers and businesses deal with their equipment as energy-efficient as possible. Frictionless measurement from a user perspective.


Challenge 3: Remote payment 2 machine

How can blockchain help, using remote payment directly to the smart meter with eg colored coins? How can we help people in need, donate to a school or non-profit? How can fraud be prevented and bureaucracy reduced by the use of blockchain? Is it possible to use payment channels via the lightning network?


Free Zone: Nuon/Vattenfall, Gasunie and New Energy Coalition are welcoming out-of-the-box and wild ideas. If you think you have a great idea for this track, come to the Track Deep Dive and discuss your hackathon-idea with the track sponsors.
