Is sharing within a single building included in this barometer?

No. In Wallonia, energy sharing within a single building, for example between the flats of an apartment block, does not need an authorisation from the CWaPE: it is notified to the distribution system operator, with which the participants then sign an agreement. It therefore produces no published decision, and this barometer cannot list it row by row. The CWaPE only publishes the total: eighteen same-building sharing schemes were in operation on 30 September 2026, with 129 offtake points. That is twice as many schemes as in energy communities, which had nine at the same date. Peer-to-peer sharing between two households is not yet operational in Wallonia: the implementing order that should set its rules has not been adopted.

Energy communities in Wallonia: the barometer

Q: How many energy communities are there in Wallonia?

As of 10 November 2026, the CWaPE, the Walloon energy regulator, lists thirteen energy communities whose notification file is complete: seven renewable energy communities (CER) and six citizen energy communities (CEC). According to the regulator's evaluation report of 30 September 2026, they bring together 222 participants. Six of the thirteen have at least one authorised sharing activity, twelve activities in total; the other seven exist legally but do not share anything yet. The figure rises with every notification and every decision. The CWaPE publishes the list on its website, and this barometer recounts it every quarter. Mappings by associations and annual reports do not always use the same scope or date, so their figures should not be added to the CWaPE's.

Q: Where can I find the list of energy communities in Wallonia?

The CWaPE publishes on its website the list of notified energy communities whose file is complete, with their name, territory, completion date and a column saying whether they have an authorised sharing activity. It publishes, separately, the list of authorised sharing activities and their modifications. Neither list gives the participants, the distribution system operators or the conditions attached to the authorisations: for that, each decision has to be opened. This barometer combines both lists and the content of the nineteen decisions in a single table and in a CSV file that can be reused under the CC BY 4.0 licence. It is updated every quarter, at the same address.

Q: How does the CWaPE authorise energy sharing?

In Wallonia, every sharing activity of an energy community must be authorised by the CWaPE before it starts, under article 35quaterdecies of the Walloon electricity decree. The community's representative files the request with the distribution system operator (DSO) to which the participants are connected; if there are several, one of them acts as a single point of contact. The DSO has ten working days to check that the file is complete, then twenty to send its technical opinion to the CWaPE. The CWaPE then decides within forty working days, a period that starts again when it asks for more information. The authorisation can come with suspensive conditions, most often the activation of quarter-hourly R3 metering. Any change, such as adding participants, follows the same procedure. Across the published decisions, the median time from request to decision was 87 days.

Q: What are some examples of energy communities in Wallonia?

The six communities with an authorised sharing activity as of 10 November 2026 follow very different models. Soleil d'Aubange, the first to be authorised in July 2024, shares the output of a solar installation owned by the town of Aubange with three private individuals. Lasnenergie, a renewable energy community limited to the municipality of Lasne, runs the largest activity, with 65 participants. ES2, a citizen energy community, runs seven activities organised around businesses, such as Energilia Wallonie and the Hannut business park. Energie Libre brings together one private individual and two small businesses on the ORES and AIEG grids. Energy For All groups businesses connected to the RESA grid. United Wallonie shares between five participants connected to ORES or REW. The full table and a link to every decision are in this barometer.

Q: How can I join one of the energy communities listed?

By contacting the community itself: it is the community, not the CWaPE, that decides to take on new participants, and each addition then goes through a request to modify its activity, filed with the distribution system operator. Two conditions come first. In a renewable energy community, your supply point must be inside its perimeter, for example the municipality of Lasne or Aubange. And your meter must be a smart meter switched to the R3 regime, which sends your consumption every quarter-hour; every conditional authorisation so far was waiting for exactly that switch. Not every community listed is looking for members, and seven of them have no authorised sharing yet. Our guide to joining an energy community in Wallonia explains the steps and what to check in the agreement before you sign.

Published on 10 November 2026 by Eric from OptimCE

Updated on 10 November 2026

As of 10 November 2026, the CWaPE has authorised twelve energy-sharing activities within energy communities in Wallonia. They belong to six of the thirteen communities with a complete file, and a single community, ES2, runs seven of them. Since July 2024, the Walloon regulator has published nineteen decisions on the subject: twelve authorisations and seven modifications. No refusal or withdrawal has been published.

The decisions are public but scattered: each is a PDF announced in the CWaPE’s register, among more than 1,500 publications, and the regulator’s own list of authorised activities says nothing about participants or conditions. This page brings the nineteen decisions together, counts them and sorts them. It is updated every quarter, at the same address, and its data can be downloaded as a CSV file.

The procedure is covered in “Create an energy community in Wallonia”, the forms and deadlines in “Energy community: CWaPE documents and deadlines”, and the differences between the legal forms in “Energy communities in Belgium: CER, CEC, CEL”. This page counts what the regulator has actually authorised.

One point of vocabulary first, because the whole count depends on it. In Wallonia, an energy community is notified to the CWaPE, which records that its file is complete. Each of its sharing activities must then be authorised by the CWaPE, on a request filed with the distribution system operator (DSO), which gives a technical opinion. A community can therefore exist without sharing anything, and one community can run several activities. This barometer counts the activities.

Key figures as of 10 November 2026

Indicator	Value
Energy communities with a complete file	13
… with at least one authorised sharing activity	6
Authorised sharing activities	12
… in a citizen energy community (CEC)	10
… in a renewable energy community (CER)	2
Authorised modifications	7
Published refusals or withdrawals	0
Initial authorisations with a suspensive condition	4 of 12
Participants stated in the initial authorisations	106
Activities in operation on 30 September 2026, according to the CWaPE	9

Assumptions: decisions and list of communities from the CWaPE, read on 10 November 2026, except the last row, taken from the evaluation report of 30 September 2026. An activity counts once, whatever its modifications. The 106 participants add up the numbers stated in the twelve initial authorisations, without later additions.

The pace is picking up: one authorisation in 2024, five in 2025 and six in 2026 so far. All seven modifications date from 2026, and five of them concern the same activity, Energilia Wallonie.

By distribution system operator

DSO	Requests filed	Activities with at least one participant connected at authorisation
ORES	8	9
RESA	2	5
REW	1	3
AIEG	1	1
AIESH	0	0

Assumptions: the authorisation request is filed with a single DSO, which acts as a single point of contact when participants are connected to several grids. That is the case for five of the twelve activities, so the second column adds up to more than twelve. A participant connected to AIESH only appears with the fifth modification of Energilia Wallonie, decided on 3 September 2026. To find out which DSO serves an address, use “Find your DSO in Belgium” or the list of DSOs by municipality.

ES2, CEC	Novandi Wallonie	ORES, RESA	not stated	3 Sep 2026	—
ES2, CEC	Centracar	ORES, RESA	not stated	3 Sep 2026	—

Assumptions: activity names as given in the decisions, which are in French. The perimeter is only stated for the two renewable energy communities, whose participants are all in a single municipality. DSOs are those of the initial authorisation: a modification sometimes adds one, such as RESA for Energie Libre or AIESH for Energilia Wallonie. Each date links to the PDF; the reference, the request date and the participants are in the CSV.

The seven authorised modifications

Decided on	Activity	What the decision authorises
15 Jan 2026	Energilia Wallonie (ES2)	Content cannot be checked: the published PDF is the initial authorisation
5 Mar 2026	Energie Libre	45 new members, production and storage installations; conditional (R3)
23 Apr 2026	Energilia Wallonie (ES2)	4 more participants and a new allocation key
13 May 2026	Energilia Wallonie (ES2)	4 more participants, 1 member fewer
13 May 2026	CEFA-AP1 (CEFA)	5 more participants, all businesses
3 Sep 2026	Energilia Wallonie (ES2)	4 more participating businesses
3 Sep 2026	Energilia Wallonie (ES2)	6 more participants, one connected to AIESH; conditional (R3)

Assumptions: the first modification of Energilia Wallonie links to the decision page, because the PDF published under its reference is the authorisation of April 2025.

The list of energy communities in Wallonia

The CWaPE publishes the list of notified communities whose file is complete. As of 10 November 2026, it has thirteen. According to the regulator’s evaluation report of 30 September 2026, seven are renewable energy communities and six citizen energy communities, with 222 participants between them.

Assumptions: names from the CWaPE list, without legal form or the “Communauté d’énergie” prefix. For the six communities whose decisions we read, the territory shown is the municipality of the registered office, not the sharing perimeter. The list does not give each community’s type, and its contact addresses are not reproduced here.

Five communities joined the list in 2026, and none has an authorised sharing activity yet. If one of them interests you, “Join an energy community in Wallonia” explains how to approach it and what to check before signing.

What the figures show

ES2 holds seven of the twelve authorised activities, all organised around businesses, and five of the seven modifications. According to the decisions, the participants are businesses only in four cases (Energilia Wallonie, Waldorado, Zoning de Hannut, Centracar) and one business plus one private individual in two others (Facq Wallonie, Novandi Wallonie); in the seventh, the only installation named belongs to the Brasserie du Bocq brewery. CEFA-AP1, the activity of Energy For All, also brings together four businesses, joined in May 2026 by five more, three of them large companies.

In the initial authorisations, the decisions mention private individuals in only four activities out of twelve, never more than three at a time: Soleil d’Aubange, Energie Libre, Facq Wallonie and Novandi Wallonie. The Energie Libre modification of March 2026 adds 45 members, 15 of them legal entities. The largest activity, Lasnenergie’s, has 65 participants, more than half of the 106 stated in the initial authorisations. Its decision does not say who they are, but the statutes restrict membership to private individuals, local authorities and small businesses based in the municipality of Lasne. United Wallonie’s decision does not state the category of its five participants either.

Only one decision names a municipality among the participants: the town of Aubange, which makes the surplus of its installation available. This case is analysed in “Energy communities: a guide for municipalities”.

One last thing in common: no community shares its own production. Every decision describes installations held by members for their own use, who share their surplus, and the CWaPE’s evaluation report confirms this for all active communities.

Seven of the thirteen communities with a complete file had no authorised activity on 10 November 2026. For the other six, the gap between the completion of the file and the first authorisation ranges from 44 days (Soleil d’Aubange) to 374 days (United Wallonie). The guide to CWaPE documents and deadlines explains why a community can exist legally without sharing a single kilowatt-hour.

A quarter between request and decision

The authorisation request is filed with the DSO. The DSO has ten working days to check that the file is complete, then twenty to send its technical opinion to the CWaPE. The CWaPE then decides within forty working days, a period that starts again when it asks for more information.

Across the eleven decisions whose request date is unambiguous, between 43 and 308 days passed from request to decision, with a median of 87 days. The two longest, Waldorado (147 days) and United Wallonie (308 days), are the ones where the CWaPE sent observations to the community before deciding. A project developer should therefore plan in quarters, not weeks.

Authorised does not mean in operation

Four initial authorisations out of twelve, and two modifications out of seven, were granted with a suspensive condition. The condition always concerns metering: switching every participant to the R3 regime, which sends the quarter-hourly load curve. Twice it also requires the injection to be marketed, and once an installation to be commissioned. Sharing only starts once the condition is met. The guide to smart meters in Wallonia explains how to request R3.

The CWaPE makes the distinction itself. Its evaluation report of 30 September 2026 counts nine activities “implemented” within communities, two in CERs and seven in CECs, with 208 offtake points. At that date, twelve had been authorised. The report does not say which ones are running.

Sharing within a single building does not go through the CWaPE: it is notified to the DSO, so it is not in the tables above. The regulator does publish the total: eighteen same-building schemes were in operation on 30 September 2026, with 129 offtake points. That is twice as many schemes as in communities, with fewer participants. Peer-to-peer sharing remains at zero: the decree provides for it, but the order that should set its rules has not been adopted.

Elsewhere in Belgium

In Brussels, the regulator Brugel does not authorise each activity but the community itself, for ten renewable years. Its list has 36 authorised communities, the first on 16 May 2023 and the latest on 17 September 2026. In Flanders, communities are not authorised but notified to the regulator, the Vlaamse Nutsregulator (formerly VREG), which counted 80 on 1 September 2025; sharing is then registered with Fluvius. These three figures do not measure the same thing and cannot be added up. For what each regime allows a household to do in practice, see “Cheaper electricity without switching supplier”.

Method and limits

What the barometer counts

One row per CWaPE decision that authorises or modifies an energy-sharing activity of an energy community. These decisions rest on article 35quaterdecies, § 3, of the Walloon electricity decree of 12 April 2001 and on articles 20 and 21 of the Walloon Government order of 17 March 2023. Sharing within a single building, which only needs a notification to the DSO, and peer-to-peer sharing, which is not yet operational, are excluded.

How it is compiled

Three CWaPE sources were cross-checked on 10 November 2026:

the register of recent documents, read page by page;
the list of authorised sharing activities, which shows the same twelve activities and seven modifications;
the list of energy communities with a complete file.

Each decision was then read in its PDF. Only what it establishes is used. A field it leaves blank stays empty in the CSV and reads “not stated” in the tables. The 2025 decisions also match the annex of the CWaPE’s 2025 annual report.

What the decisions say, and what they leave out

They give the community and its company number, the activity, the participants’ DSOs and number, the installations made available, the DSO’s opinion and the conditions. They give neither the peak power in kilowatt-peak, nor the start date, nor the price of a shared kilowatt-hour, nor the details of the allocation key. We reproduce no private individual’s name.

Discrepancies found

CD-26a15-CWaPE-1232 (first modification of Energilia Wallonie): the published PDF is the initial authorisation. Later decisions confirm the date, not the content.
CD-26e13-CWaPE-1262: the CWaPE page shows CD-26d23; we follow the PDF, which later decisions also cite.
Centracar: the PDF reads CD-26i03-CWaPE-1231, the page and the list of activities 1291, which we use.
Two request dates for Zoning de Hannut (8 October or 26 June 2025) and for the Energie Libre modification (3 or 7 July 2025). Zoning de Hannut is left out of the time calculation.

Key takeaways

Twelve authorised sharing activities, in six communities out of thirteen, through nineteen CWaPE decisions published since July 2024, with no refusal or withdrawal.
ES2 runs seven activities out of twelve, almost all organised around businesses.
The community is notified, each sharing activity is authorised: seven communities with a complete file share nothing yet.
Allow a quarter between request and decision: 87 days at the median.
Authorised does not mean in operation: a third of the authorisations wait for R3 metering, and the CWaPE counted nine activities in operation on 30 September 2026.
The data is open: a CSV under the CC BY 4.0 licence, updated every quarter.

Prepare your sharing activity’s CWaPE file

OptimCE is an open-source platform for managing energy communities, currently in alpha. It opens one file per sharing operation and prefills the CWaPE’s official forms from your community’s members, supply points and meters. You review, you file it yourself, and the application computes the deadlines from the filing date you record.

FAQ

How many energy communities are there in Wallonia?

Thirteen with a complete file as of 10 November 2026, according to the CWaPE: seven CERs and six CECs, with 222 participants. Six of them have at least one authorised sharing activity, twelve in total.

Where can I find the list of energy communities in Wallonia?

The CWaPE publishes the list of communities with a complete file and, separately, the list of authorised activities, without participants or conditions. This barometer combines both with the content of the nineteen decisions, as a table and as a CSV file.

The request is filed with the DSO, which gives a technical opinion; the CWaPE then decides within forty working days. Any change follows the same procedure. The observed median between request and decision is 87 days.

What are some examples of energy communities in Wallonia?

Soleil d’Aubange, Lasnenergie with its 65 participants, ES2 with its seven business activities, Energie Libre, Energy For All and United Wallonie: these are the six communities sharing as of 10 November 2026.

No: it is notified to the DSO, without a CWaPE decision. The regulator counted eighteen such schemes in operation on 30 September 2026. Peer-to-peer sharing is not yet operational.

How can I join one of the energy communities listed?

By contacting the community, which then asks for its activity to be modified. You need a smart meter on the R3 regime and, in a CER, a supply point inside the perimeter. “Join an energy community in Wallonia” explains the steps.
