The Berlin Energy and Climate Protection Program 2030 gives solar energy a central role, as it is the most important renewable energy source that can be developed locally. The state government wants to cover 25 percent of Berlin's electricity supply from solar energy as quickly as possible. In the densely populated city, this also requires the roofs of apartment buildings to be used. In the discussion format Wandelwecker on 8 September 2021, Fabian Zuber from the Reiner Lemoine Foundation and Ecologic Institute's Katharina Umpfenbach discussed options transforming the regulation of tenant electricity and local solar power supply. The event was moderated by Valentin Tappeser from IÖW. It became clear that solar expansion can only be achieved at the required speed with a fundamentally new regulatory approach centered around joint self-supply that intelligently links on-site power generation via solar systems with charging of electric vehicles and heat generation.
On 17 June 2021, representatives from Berlin's public administration, business and civil society discussed how to accelerate the expansion of tenant electricity in Berlin in the virtual expert workshop of the StromNachbarn project. Practical experience inputs enriched the discussion.
The innovation field of construction is a resource-relevant field in Berlin – in 2017, the construction sector accounted for about 22 percent of the raw material input of the state of Berlin. Currently, the recycling rate for mineral construction waste is around 50 percent, and is expected to increase to more than 60 percent by 2030. Circular economy approaches in the field of construction have to cover the entire life cycle: from the design of durable and deconstructable structures to the use-phase and material-preserving re-use to circular business models.
Tenant electricity systems generate solar power on apartment buildings and deliver it directly to the households in the building. In a new study, Katharina Umpfenbach and Ricarda Faber (Ecologic Institute) evaluate the effects of the existing tenant electricity systems in Berlin. The bottom line: Berlin's 74 tenant electricity projects have positive ecological and socio-economic effects, but these remain low compared to the technically available potential. Currently, only 1 % of the tenant electricity potential is used. The study is available for download.
Photovoltaic technology is a key lever for decarbonising Berlin's power consumption and for social participation in the transformation process, especially for tenants. Therefore, solar energy and projects on rental apartment blocks are key elements of the Berlin Senate's Energy and Climate Protection Programme. In the research project "ElectricityNeighbours", Ecologic Institute and IÖW evaluate the experience gained so far in implementing such prosumer projects in Berlin, outline innovation potentials for the field and develop ideas on how the regulatory framework can be further developed. In doing so, the team looks beyond pure tenant electricity projects to the potentials of sector coupling.
