Battery storage Parteon in Wormerveer

Wormerveer, Netherlands Data and ICT solutions, Energy Communities, Environment and Resource efficiency, Local social sustainability


Wichard van der Veen social housing organisation in the Netherlands introduced a Pilot with Smart Battery at the Parteon Office. This office is benefitting from solar energy (190 solar panels at office roof) and with the smart battery it aims combining smart Storage with Solar Energy and contributing to grid optimization.


The pilot is located in Wormerveer (20 km Northwest of Amsterdam)

The social housing organisation has approx. 17,200 premises; 16,000 houses; 1,000
garage/storage; 200 miscellaneous (210 internal + external staff)

The sustainability target of the organisation is to have all premises CO2 neutral by 2050.

Issues tackled

With more Solar Panels the organisation creates imbalance after 2025 (Generation and Consumption are not equal).
The own Consumption of Solar Energy is usually 30%- 60%. The other part of power/energy should be transported back to the Grid.

Therefore, the grid suppliers have to invest substantially: These investments have to be earned back. In addition, there is a long waiting lists for larger connections and obtaining connection at all.

Stages of the pilot:

The System installation and operational testing was carried out in September 2021.
The social housing organisation is gaining experience with different strategies: Sept 2021 Apr 2022

  • Increase own consumption solar energy
  • Reduce peaks at connection peakshaving
  • Pilot: grid balancing
  • (Dis)Chargeb attery at high respectively low energy prices
  • Communicate with Grid Supplier Liander ) to determine impact

 August 2022

  • Qualification Balancing Grid
  • New supplier PetaWatt

October 2022

  • Start generating revenues from Grid

Actors involved

  • Municipality Zaanstad
  • Wichard van der Veen (Parteon)
  • Rens Smal (Enerzien)

Actions carried out

  • Combining Smart Storage with Solar Energy and contribution to Grid optimization
  • Peakshaving of Elevators and Electric Cooking
  • Smaller power connection to the Grid and hence speed being connected at all
  • Enabling quick power connection to new Flexible Housing solutions (Ukrainian Refugees; local young people , starting at housing market)


  • Improves/ lowers energy consumption of the tenants
  • Contributes to societal challenges of energy consumption
  • Avoids slowdown of sustainability programs due to grid congestions


The effects of a battery:
•Smaller grid connection
•Less time needed for new connection
•Reduce pressure on grid
•CO2 reduction

Next steps
•Incorporate the pilot lessons in project development
•Analysis / expectation power usage and solar generation potential
•Assessing required battery size / power, peakshaving potential and power usage
•Assessing investment and operational costs
•Technical,Economic and Sustainability considerations
•Available subsidies ( province North Holland): 50% technical advice up to €75k

Why it works

  • Selection of right location. Ventilation and Fire prevention are important;
  • New technique for all parties , including supplier battery system;
  • Right Software is an important condition for a well functioning battery;
  • Most important: selecting supplier with proven track record in this new market.
