PowerParking is an ERDF project in which large carparks become renewable energy plants, connected with a smart grid to EV chargers and the adjacent buildings.
PowerParking is an innovative pilot project to transform (large) parkings to decentralised sustainable energy plants. It provides a solution to the increasing imbalances on the grid and the need for a more flexible energy system.
At Lelystad Airport (LA) and the adjacent Lelystad Airport Businesspark (LAB), part of the car parks (2x 100 places with 0,5 MW solar panels) will be covered by a carport with solar panels. The solar energy will be used to charge electric vehicles, for public lightning and for other needs of the terminal and business environment. A surplus of energy will be temporarily stored in the batteries of the parked vehicles and/or extra storage capacity.
The system will be connected to a public DC (Direct Current) net. Each part of the construction is being developed in a sustainable way.
A smart ICT system decides on where the energy is going. Part of the project is to further develop the business case, so the concept can be built without subsidies in the future.
The PowerParking will be tested on small scale at the Green Village of Delft Technical University. There will also be a socio/economic research among users: when will car owners allow to use the batteries of their cars?
Provincie Flevoland has developed the project together with LA, Schiphol Group, LAB, Delft Technical University, Pontis Engineering (SME engineering of composite constructions), Eneco (DSO) en Alfen (SME in electric engineering and construction).
PowerParking receives € 1,2 M from the ERDF programme and € 0,5 M co-financing from the Province of Flevoland. The rest of the investments (in total € 3,1 M) come from the project partners.
These costs include the cost of human resources.
Evidence of success
The project is still ongoing, so the results can be added to the good practice desciption in 2018. However, there is a large interest already in the concept (for example from the national railway operator for their parks and rides at stations).
The system demands new business models (who is earning what and when) which is rather complicated if you work with 8 partners together in the project.
To add the DC component to the project is quite innovative, but has more technical complications that we had foreseen.
Potential for learning or transfer
The challenge is to make PowerParking economically viable without subsidy. From then, the potential of transfer is very large, since every country has large car parks, which can be transferred. Even if the number of electric cars is not very large yet, the PowerParking can deliver energy to the environment. Since car parks are normally situated in an environment where much energy is needed.
