Informal Round Table Hosted by RITTERWALD and AGFW Focusing on Landlord-to-Tenant Electricity
With a focus on landlord-to-tenant electricity (“Mieterstrom”), RITTERWALD and AGFW hosted a meeting on September 21, 2017 in continuation of the Informal Round Table format they initiated last year.
The focus on the topic of landlord-to-tenant electricity was prompted partly by the recent ordinance enacted in Germany on landlord-to-tenant electricity supplied from photovoltaic (PV) cells. Aside from considering the questions around supplying PV power to tenants, the subject merits a broader discussion of the economic and legal framework of the landlord-to-tenant electricity supply business model. Aspects to consider include the definition of the customer’s system, and possible combinations of photovoltaic systems, cogeneration plants (CHP), storage systems and district heating. There is also the question of measuring the energy rating: Is it possible to individually determine the primary energy factor for landlord-to-tenant electricity supplies coming from PV and CHP systems and combinations thereof in a building or neighborhood, and if so, how? Linked to this is the methodology of CHP fuel allocation, which is currently in the process of transitioning from the power bonus method to the dual Carnot efficiency/mechanical equivalent of heat method.
Excerpt from the program:
Landlord-to-Tenant Electricity Supply – What Opportunities Do the Two Industries See in the Business Model?
Stefan Fölsch, GEWOBA Energie GmbH
Nicole Hilden, RheinEnergie AG
Round table discussions on:
- Legal framework including definition of customer systems
- Parameters for the economic efficiency of landlord-to-tenant electricity supply
- PV, CHPs, combinations (e.g. storage systems, district heating)
- Cooperation and competition – Where do housing companies and contractors overlap?
- Starting point: Energy rating of electricity/landlord-to-tenant electricity, CHP, district heating
- Determination of building-specific primary energy factors for landlord-to-tenant electricity supplies from PV, CHP and combinations
- Transition of CHP measurement from power bonus to Carnot efficiency/mechanical equivalent of heat method
- Significance for the overall consideration of buildings and neighborhoods
