Renewable Energy
Communities.
JAF Renováveis structures and operates Renewable Energy Communities for municipalities, neighbourhoods, residential blocks and business parks. Solar generation shared locally, with a measurable benefit for each consumer.
A Renewable Energy Community (CER) lets several consumers share locally generated solar power – cutting bills, adding value to the area and reducing dependence on the traditional grid. We structure, license, install and operate the community from end to end.
- Technical and legal assessment – feasibility, sizing, internal rules, member contracts and the relationship with the grid operator.
- Ongoing operation – running the metering platform, allocating surplus, billing, reporting and optimisation across the life of the community.
What do you need
to clear up first?
An energy community is as much an organisational model as it is an installation. Most early questions are about the first part.
Whether it fits my case
What a community adds to a self-consumption system.
Who can take part
The settings where sharing between participants is possible.
How one is set up
The stages, from the feasibility assessment through to operation.
I already generate and want to share
How existing generation fits into a sharing model.
Generating is one thing.
Sharing it out is another.
Generation is the infrastructure. The community sets how that energy is shared out between its members.
The system generates
Solar panels sized for the group, not for a single consumer.
The energy can wait
Where the profile justifies it, batteries shift the energy to the hours when it is needed.
The energy is shared out
This is the part that only exists in a community: the energy generated is allocated to the participants under a model they agree between them.
Where sharing
usually makes sense.
What these settings have in common is physical proximity and consumption profiles that complement each other through the day.
Business parks
Neighbouring companies with daytime consumption and available roofs or land.
Housing blocks and neighbourhoods
Housing with consumption spread through the day and common areas where generation can be installed.
Municipalities and public bodies
Municipal facilities close to each other, with steady, predictable consumption.
Groups of sites
Several sites of the same organisation, or of different ones, in the same area.
Five steps to your CER.
Technical, legal and financial assessment – consumption profile of prospective members, space available for generation and the regulatory framework.
Setting up the managing entity, drafting the internal rules, member contracts and registration with the DGEG.
Photovoltaic design, permits, grid connection and certification – under Grupo JAF technical coordination.
Building the solar installation, setting up the smart metering platform and starting shared operation.
Day-to-day management, maintenance, member billing and monthly reports on generation, consumption, savings and avoided emissions.
What a CER typically delivers.
Typical ranges from communities already in operation, not a guaranteed outcome. The figure for any given project depends on the consumption profile, installed capacity, number of members and the tariff in force, and is established in the feasibility study.
A community still
needs generation.
A community needs energy generated somewhere. When that generation does not yet exist, the same Group installs it.
Want to know whether a community fits your case?
The setting, a rough idea of how many participants there would be and where they are is enough. The feasibility assessment answers the rest.
Energy communities are one strand of the Group's Energy area. For generation dedicated to a single consumer, the route is self-consumption under Renewables; to buy supply from the grid, it is energy retail.
