Purotie 3 garage: Charging points for the housing company - this is how it succeeds!
A Helsinki-based housing company decided to order a charging solution and service. In a large-scale charging site, the advantages of the eParking service were dynamic load management, easy consumption monitoring, and consolidated invoicing.
The parking garage was warm and there was no charging infrastructure there before. The site had 113 partner spaces in a heated parking garage, without heating posts. The goal was to enable 11 kW electric car charging and update the electrical infrastructure.
Works carried out by the installation company:
4 distribution center installation
Expansion of the main electrical substation
Separate measurement center for charging
Costs for charging points:
The total cost of the electrical work was approximately €40,000 (including electrical survey, distribution centers, main center, and measurement center).
Cable installation for a parking space €250 / space
Charging device installation €100 / device
85 cable ready devices were ordered, and ultimately 35 charging devices were put into use.
The charging devices were mainly Type 2 11 kW chargers. The devices were ordered from Satmatic , a partner of eParking.
Residents could choose between 3.6 kW and 11 kW devices (prices: €1,100 and €1,500, incl. VAT).
Billing and payments:
Electricity is billed according to consumption through the eParking system.
Payments are transferred directly to the housing company's account without commission.
The housing company's VAT rate for this property was 0%.
The cost of the invoicing service is charged directly to the shareholders, and there are no additional costs for the housing company.
The average cost per resident was approximately €2,100 (including charger, installation, cabling and share of the electrician's work). The housing association managed the project itself and received 50% ARA subsidy for it.
Notes on the project
This case shows that expanding the charging capacity of parking garages can be successful in an efficient and scalable way. The project invested in the future: although 35 charging devices were initially introduced, the garage now has a total of 85 charging points.
Because the ePole stations communicate wirelessly via a mesh network formed by a single connection device, there was no need to install expensive Ethernet wiring. This project is a good example of how easy and flexible it can be to build an electric vehicle charging infrastructure.
