Digitalization and renewable energies are revolutionizing the business of trading and selling electricity. In November 2017, the utility Wuppertaler Stadtwerke became the world’s first municipal enterprise to launch a green power trading center, where the transactions are carried out using blockchain technology. Customers can obtain their electricity from local green power providers and create their own energy mix. Acting as an intermediary between producers and consumers, the municipal utility takes care of the billing.
For solar power generators, direct marketing also offers new avenues for sales; for utilities and housing companies, it creates new opportunities for customer retention. With last year’s Landlord-to-Tenant Electricity Act, the German federal government created the first regulatory framework for tenant power. The government has also incorporated a new subsidy known as the tenant electricity surcharge into the Renewable Energy Sources Act (EEG), for power from new photovoltaic installations with a capacity of up to 100 kW.
Everyone benefits from tenant power projects: Installing a photovoltaic system increases the value of the property for the owner, and tenants are able to purchase cheap, clean power and reduce their living costs. Housing companies can create attractive residential properties which can be marketed even more successfully. Independent service provider can offer direct marketing in the form of contracting and can take on the planning, financing and operation of photovoltaic installations and the supply of the electricity.
