PV4residents – Innovative Finance Service and Business Model for PV Power Plants of Multiple Dwellings with On-site Use of Electricity

The aim is to develop a business model, which enables a stronger penetration of PV plants on multiple dwellings with self-consumption of produced electricity by the residents. Involvement of the municipality allows to deliver surplus electricity for their needs. Basis of the business model is an analysis of the technical, legal, administrative, user related and economic barriers with participation of stakeholders and to identify best practice solutions.

Short Description

ongoing

Summary

Starting point / motivation

Residents of multiple dwellings are currently not able to install on their roofs their own photovoltaic (PV) plants to use the produced electricity mainly for their own electricity needs. Through involvement of the municipality the surplus electricity can be used by them for their local energy needs. Many open questions have to be answered with the result that the available roofs are to a large extent not used. Those PV plants which are currently installed are only used to feed into the public grid and without an involvement of the residents.

Still missing are answers of legal, administrative, user-specific and economic questions, from which a concrete business model can be derived, and which then can be offered to the residents of multiple dwellings. A successful solution of these questions is represented by the added value to make available a large portion the untapped potential of roofs and to involve a wider range of the population. Because of the focus on self-consumption, the public grid and the electricity related infrastructure will be disburdened.

Contents and goals

The objective of the exploration is to compile the existing knowledge – also from other countries - to close scientific gaps, to find solutions for the barriers, to discuss these items with involved stakeholders and then to develop a corresponding financing service and business model. The core of this exploration consists in the answers to the legal and administrative issues. Among other topics, it is planned to evaluate the legal form of an energy cooperative society, which promises to deliver electricity within the multiple dwelling to the residents, who are members of the energy cooperative. In this cooperative, members would be the residents of the multiple dwelling, the housing associations, but also the municipality/community, the local utility and network operator.

Methods

In step 1 all existing knowledge on this topic is collected. Step 2 comprises a detailed analysis of all necessary issues, which include technical, legal, administrative, user-specific and economic aspects and parameters. In step 3 these results are evaluated, summarized and used for the final definition of the final finance, service and business model. In this process the future users of cooperative PV plants have to be involved from the beginning in order to include their preferences. On the basis of two concrete multiple dwelling buildings of two large housing companies in Graz and Salzburg, a technical and economic evaluation of such a cooperative PV plant is carried out and the feasibility of such a business model is checked.

Besides the residents as future users, the housing companies as well as the municipalities of Graz and Salzburg, also one utility and network operator, the energy departments of the Austrian State of Salzburg and of the Austrian State of Styria and the “Austrian Association of Cities and Towns” are involved as stakeholders and will, because of their high interest in this topic, contribute their knowledge.

Expected results

Expected results and knowledge include

  • A finalized, concrete, and robust finance, service and business model with the participation of all necessary partners for the promotion of electricity self-production from a cooperative PV plant on a multiple dwelling;

  • A directive how residents of multiple dwellings can participate directly in self-consumption of PV electricity;

  • A plan how after a positive conclusion of this exploration additional projects in direction of a concrete implementation can be developed.
