PV plant with storage design in Grenoble

Design and implement a PV plant on the roof of a tertiary building with smart power management and storage features with the aim to self-consume the photovoltaic electricity, in order to not be any more depending of the French feed-in-tariff; and showing the conditions of a new business model for PV with onsite storage and consumption, applicable more largely on tertiary buildings.

 

Location : Grenoble

Project team :  ALEC / HESPUL Municipality of Grenoble

Progress / Due date : end 2017

Replication : ALEC will disseminate and help in the replication of similar projects

The project

Many local community organisations would like to reduce their environmental footprint and produce their own energy, for instance with PV panels. This would also create awareness in neighbourhoods and engage people in the transition towards clean energy. In France, the very low feed-in-tariff for tertiary buildings is holding back many of those projects and leaves a lot of roofs unused.

ALEC has recently built a new highly energy efficient “Esp’ACE – Air, Climate, Energy – building” in Grenoble metropolitan area that hosts environmental oriented associations, implementing awareness actions towards professionals and citizens. Within City-zen it will demonstrate that there exists a specific business model for PV by combining low cost technologies for flat roof integration of PV panels, consumption of the electricity directly in the building (self-supply), smart management and storage features. It makes sense to set up this innovative plant on the building roof. This building is furthermore representative of many existing or new building that could reproduce this kind of project.

The result

The project will not only allow the partners in Grenoble to benefit from their own renewable energy and reduce the electricity bill, but will also serve as an example to other community organizations elsewhere in France. ALEC will disseminate and help in the replication of similar projects. ALEC will expose the advantages/limits of different legal/financial possibilities and provide a model for contracting with building users to secure payback to the plant owner.

The next step

So far the project has been proposed to and was accepted by the building users. Apart from certain administrative activities, juridical aspects have been investigated to define who will invest, how to share the investment cost and the further benefits of the plant, with a long term vision as a starting point. Consultation for tendering has been launched in February 2017, and after the formal vote of by ALEC administrative council to confirm the project, the installation is planned for summer 2017.
