98kWp PV system and connection to the Virtual Power Plant

Munich Electric-Renewable Energy Sources

General facts

Description & main goal

98 kWp PV system and connection to the virtual power plant //
During this project several photovoltaic (PV) systems were installed on both new and existing/refurbished municipal schools in the project area by the City of Munich. These systems deliver a minimum of 118 kWp and get partly connected to a virtual power plant.
Further PV system with 60kWp is in preparation (Month 45)

Deployment area
Neuaubing-Westkreuz, Munich

Implementation status

In which phase is the project?
Transition from preparation/planning phase to implementation phase

What is the current implementation status/ what is the current activity step?
The installation of photovoltaic will (if possible) take place within the refurbishment measures. Search for new sites and objects for implementation of projects with high  public recognition value (public spaces, crowd funding objects)

Risk and challenges

Which risks & challenges is the project currently facing?
  • Photovoltaic installation on refurbishment buildings might not be feasible due to static constraints of the building structure.
Which are critical or seem invincible? Please provide a detailed description
Without municipal subsidies operation is not economically feasible (first10 years)

Lessons Learned and Recommendations

Which lessons learned can be derived up to this point from the implementation process?

Installation of photovoltaic systems on refurbishment buildings require additional static studies of the roof

Next steps & To Do ́s

Please shortly outline the next steps planned for the implementation of the project.
Planning of connection of photovoltaic systems to the virtual power plant

Implementation status

In which phase is the project?
Transition from preparation phase to implementation phase

What is the current implementation status/ what is the current activity step?    
The installation of photovoltaic (PV) will 
a) take place alongside the other refurbishment measures and 
b) on other, also additional objects. Possible sites and objects for implementation of PV systems are currently being acquired. In one case one project is already in planning, yet still not confirmed. Additional features like small e-mobility station with electricity storage are included in this case.

Lessons Learned and Recommendations

Which lessons learned can be derived up to this point from the implementation process?

There is need of strong collaboration within the various  involved  City departments to innovatively  integrate the stand alone projects and gather synergies and rise impact

What could be done better in comparable future projects (what needs to be done and what needs to be prevented)?

To set up a collaboration already in the planning phase
