Demo Project 6: Distributed Positive Energy Block (DPEB)

Enable the future: DPEBs as a crucial part in the energy transition.

Vision (DP06) in a nutshell

DP06 assessed planning regulations and permission requirements, and then procured and installed the technologies required to create an overall positive energy balance for the demonstration areas. The installed technologies generate both electricity and heat to supply the block’s energy demand using local and distributed renewable energy sources (RES) and local storage, as well as microgrid controllers, electric vehicle (EV) charging points, and substations. Smart metres gather data to enable the correct sizing of the technologies for a DPEB, enable energy optimisation and balancing, and ultimately enable energy trading amongst citizens in the block.

Problem addressed & specific objective

The concept of Positive Energy Blocks (dPEBs) was introduced through the Strategic Energy Technology (SET) Plan. The SET Plan defined, concretized, and aimed at rolling out dPEBs as a crucial part of and means to realising and obtaining success on the transition to a low-carbon, green, and renewable energy future. 

The +CityxChange project has created a framework for a stepped approach to the creation of a DPEB, which can be replicated by any EU city. There are a number of key steps that must be taken for its creation, being (i) reduce demand, (ii) create supply, (iii) actively manage the energy in the block, (iv) enable electrification of vehicles and (v) trade energy and flexibility. The +CityxChange project framework has been designed so that the neighbourhood/block can set their own objectives and timelines for becoming a DPEB and can use the tools, services and technologies that are most appropriate to their location and governance.

PED Grid Design toolbox:

The PED Grid Design toolbox is an integrated tool for design, analysis and grid operation of a local energy system including use of storage and grid balancing. The models in the toolbox include reports presented as dashboards/tables with results of calculations. It also includes topology descriptions of the local grid which is a part of the community grid and/or PEB. The calculated results are easily exported to third parties for further processes and tasks like settlement and invoice. The eMobility is managed as local energy storage and is included as local energy resources with information represented like time series in the same way as other local resources and/or forecasts.

Gkinetic Tidal Turbine for Shallow Rivers:

The Gkinetic Tidal Turbine for Shallow Rivers is a 10kW Hydrokinetic Turbine that can be deployed in a variety of sites. Two vertical axis tidal turbines are fixed to a standard deployment platform to provide a 10kW floating hydrokinetic solution, a plug and play hydrokinetic turbine that extracts the kinetic energy from flowing water and converts it to electricity. The power generated is clean, zero carbon, locally generated and 100% predictable unlike solar or wind.  The unique selling point of the GKinetic hydrokinetic turbine system is the ability to generate significant power at relatively low flow speeds, averaging 2 metres per second (mps).

Recommendations for cities:

  • The selection of viable buildings for the dPEB is crucial; detailed mapping and analyses are needed (suitability, existing RES, efficiency potential, etc.)
