Implementation status

In which phase is the project?
Planning phase

What is the current implementation status/ what is the current activity step?    
The installation of photovoltaic (PV) will 
a) take place within the refurbishment measures and 
b) on other, also new objects. Possible sites and objects for implementation of PV systems are actually 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.

Risk and challenges

Which risks & challenges is the project currently facing?
  • Connection to the virtual power plant might not be suitable due to additional technical requirements with effort
  • Potential for the connection to the virtual power plant is low according to limited energy production exceeding the self-consumption
  • Refurbishment buildings might not be suitable in regard to static requirements for installing PV
  • There are health concerns (e.g. electro smog) limiting the willingness of private owners for installation of PV systems 
Which are critical or seem invincible? Please provide a detailed description
  • Static studies causing additional costs 
  • Limited energy production
     

Lessons Learned and Recommendations

Which lessons learned can be derived up to this point from the implementation process?
  • Installation of systems on refurbishment buildings require additional static studies of the roof
What could be done better in comparable future projects (what needs to be done and what needs to be prevented)?
  • To foresee photovoltaic systems as potential refurbishment measure right in the beginning of the technical studies in order to figure out if there is a feasible business model

Risk and challenges

Which risks & challenges is the project currently facing?
  • Potential for the connection to the virtual power plant is low according to limited energy production exceeding the self-consumption
Which are critical or seem invincible? Please provide a detailed description
  • Static studies causing additional costs
  • Limited energy production
Which previously identified risks and challenges have you managed successfully and how
  • Installation on refurbishment is possible due to the results of static and further technical studies 
  • health concerns (e.g. electro smog) have been dismantled due to an intensive advising process

Lessons Learned and Recommendations

Which lessons learned can be derived up to this point from the implementation process?
  • Private project partners need technical and legal advice (workshops, information meetings…)
Next steps & To Do ́s

Please shortly outline the next steps planned for the implementation of the project.

  • The photovoltaic system will be installed during the ongoing refubishment (by November 2018)
