First local energy community is live! LEF in Hoog Dalem – Energy21

This is how local an energy community can be

LEF, based in Hoog Dalem, is all about making the power grid smarter. In this pilot project, an energy community – formed by a group of approximately 15 homeowners – generates its own electricity. The purpose is self-consumption or to mutually exchange this electricity within the community and settle the price immediately. When self-production falls short, energy can be bought from the grid through the use of flexibility or ancillary (grid) services. 

LEF not only stands for Local, Energy and Flexibility, but is also the Dutch word for courage: the act of taking a bold decision to participate in this project and to contribute to innovations in the energy market. 

The essence of the project 

A group of homeowners are generating their own electricity for self-consumption or to be mutually exchanged within the community, settling the price immediately through the application of blockchain technology. While stimulating smart usage of the self-generated energy, there’s also the option to buy or sell the energy on the market when this is more financially beneficial. Combining sensors in the local power grid with data exchanges and allowing them to interact with smart home systems means that smart devices (like thermostats, washing machines and dishwashers) can be intelligently managed. The energy generated is therefore immediately exchanged or stored in the battery storage system. The surplus of energy can be traded on the national energy market. A win-win: the community becomes predominantly self-sufficient and the power grid is greatly relieved. 

For now and for later 

In this project, the residents work together with technology pioneer ABB, energy expert Energy21, software company iLeco and distribution system operator Stedin. Together, they’ll find the answers to questions such as: 

  • What is the most efficient way for the local energy market to function while providing benefits for the residents as well as the grid administrator? 
  • How can we accomplish the mutual exchange of energy and data? 
  • How can we optimally align energy supply and demand? 
  • Can LEF be applied country-wide? 
  • Is the Layered Energy System, the core philosophy on which LEF is based, a good way to locally exchange energy? 

Based in Hoog Dalem, LEF offers insights and practical tools. In addition, major adjustments to the power grid can be prevented with LEF’s help. That way, we keep our power supply reliable as well as affordable – for this generation and the next.  Read the press release here (in Dutch):

Layered Energy System


Layered Energy System: exploring a new energy market model

Towards a sustainable energy ecosystem with the Layered Energy System

Our energy market model has been set up top-down and centralistic, from production (via transmission and distribution) to consumption. But our current model is no longer fit-for-purpose. For example the model is not suitable for end-users with solar panels that generate a surplus of energy and feed it back into the energy network (bottom-up). This leads to questions that urgently need to be answered. 

Local energy community
A very important question regarding a (new) sustainable energy ecosystem is: what should be the role of local energy communities in our energy system? Distributed generation and flexibility are part of the cause as well as the solution of the challenges the energy system faces. Demand-response by aggregators is currently not very attractive for the owners of flexibility (the end-user) nor is it a scalable solution in the long run. At the same time, local communities of end-users are founded and are experimenting with energy sharing, flexibility and with distributed network technologies (like blockchain). We believe that this system-averse social trend is an important factor in the energy transition.

Layered Energy System Concept
In close co-operation with the Dutch distribution grid operator Stedin, Energy21 developed the Layered Energy System (LES). In an earlier phase we explored the concept of local energy communities and local markets. Now, we have described more detailed the mechanics and roles of stakeholders in a Layered Energy System. We believe that the concept of LES provides a feasible elaboration of the “Citizens Energy Community” as mentioned in the EU Clean energy package.

LES offers insights and possible solutions to stakeholders’ issues moving towards a sustainable energy ecosystem. Energy21 is proud to present the LES Whitepaper and continues to discuss the topic with all stakeholders in the energy ecosystem.
