About the cooperative

The shares of Coopérnico are not subject to any kind of taxation.
However, if there is a distribution of dividends, they are subject to a definitive withholding tax, at the rate of 28% for the year 2018.
Cooperatives are autonomous, non-profit-making, free-constituent collective bodies with varying capital and composition, aimed at meeting the economic, social and cultural needs and aspirations of their members, and which are governed by a set of common principles based on solidarity and democracy.
The seven cooperative principles are: 

1. Free and voluntary membership
Cooperatives are voluntary organizations open to all people without social, racial, political or religious and gender discrimination. 

2. Democratic management by members
Cooperatives are democratic organizations controlled by cooperators, who participate actively in policy-making and decision-making, and are guaranteed the right to vote, on an equal footing with all members.

3. Members' economic participation
Members contribute equitably and democratically control the capital of their cooperatives. At least part of this capital is normally common property of the cooperative. Cooperators shall receive, when appropriate, limited remuneration for subscribed capital as a condition for membership and shall allocate surpluses to one or more of the following objectives:
  • development of their cooperatives, possibly through the creation of reserves, some of which at least will be indivisible;
  • benefit of members in the proportion of their transactions with the cooperative (return);
  • support for other activities approved by members. 

4. Autonomy and independence
Cooperatives are autonomous self-help organizations controlled by their members.If they enter into agreements with other organizations, including governments, or resort to external funds, they should ensure democratic control by their members and autonomy as cooperatives.

5. Education, training and information
Cooperatives shall promote the education and training of their members, elected representatives, managers and workers so that they can contribute effectively to the development of their cooperatives. They should inform the public, particularly young people and opinion leaders, about the nature and advantages of cooperation.

6. Cooperation between cooperatives
Cooperatives serve their members more effectively and strengthen the cooperative movement by working together through local, regional, national and international structures.

7. Concern with the community
Cooperatives work for the sustainable development of their communities, through policies approved by their members.
It is the economic participation of the members. The members contribute equitably to the capital of the cooperative and control it democratically. This capital is usually common property of the cooperative and condition for membership. The minimum entry may not, however, be less than the equivalent of three equity shares which, in the case of Coopérnico, have a value of € 60. Only after the adhesion, and payment of the respective titles, can a member be involved in activities and participate in projects of the cooperative.
There are several ways to participate in our project, namely: 
  1. You can become a member of the cooperative. In order to join, just fill in the form and buy at least 3 shares, with a total cost of 60 €;
  2. You can be an investor-member participating in our projects: investment in Coopérnico´s renewable energy projects has interesting long-term returns that combine economic benefits with environmental and social benefits;
  3. You can participate in a working group: Coopérnico seeks to evolve through the contribution of its members;
  4. You can cooperate voluntarily, if you have knowledge and/or experience that you believe may be useful to us;
  5. You can be potential partner/supplier. We always try to turn to local suppliers, so we appreciate you sending all the information that you deem appropriate.
These bonds do not necessarily have a fixed remuneration and can only be remunerated if there is distribution of surplus resulting from the activity. Such surpluses may also be earmarked for the development of the cooperative, possibly through the creation of reserves, to the benefit of members in proportion to their transactions with the cooperative, or to support for other activities approved by members after fulfilling all legal obligations established for cooperative organizations.
We are often asked, "What do people gain by becoming members of the Coopérnico?" 
And the answer is always the same: "There are multiple benefits." And it's true. There are those who join Coopérnico because they believe in a decentralized, renewable model or because they want to be part of a civic movement and change to a reality where people can be part of the decision process. There are also those who come because they see a good opportunity to use their savings in a positive way through investing in renewable energy production projects. And there are those that review themselves a little in all of the above. Still, we always ask, "Should there be more benefits for Coopérnico members?" Faithful to our mission and vision for the energetic future, we want to go even further and give people more reasons to join us. That´s why, from 2015 we will make renewable energy enter our homes and businesses, making possible the purchase of green electricity, at a fair price, through the cooperative of which we are all owners.
Coopérnico, the first social company, to provide green electricity in Portugal.
Based on the bylaws, members may be individuals over the age of eighteen and legal persons who, commensurate with the objectives of the Cooperative, are admitted as such by the management.Admission as an effective member of the Cooperative is made through a written request, electronic mail or platform made available on the cooperative's website.Once the application has been submitted and payment of the equity shares has been made, the proponent is conditionally admitted as an effective cooperator, and the Director must, within a period of sixty days, ratify or revoke the said conditional admission, without the need for a statement of reasons. In the event that the Board decides to revoke conditional admission, the cooperative shall return the amount of subscribed social capital to the tenderer within seven working days without any other compensation.
A renewable cooperative is a cooperative whose objective is to promote sustainable development and a cleaner energy sector by investing in renewable energy, thereby satisfying the social, economic and environmental needs of all citizens.
Renewable energies have many advantages: 

  • They are sources of clean energy, without direct emission of any pollutants.
  • They use renewable sources, which means they do not contribute to the depletion of the planet's resources.
  • They do not contribute to climate change because they do not cause Carbon Dioxide emissions. 

Coopérnico's projects, by promoting the production of renewable electricity through small projects, also promote decentralized production, contributing to the decrease use of electricity grids and therefore less waste of energy during its transport throughout the power grid.
According to the statutes of the cooperative, more specifically under Article 16 (1) (b), only natural persons over 18 years of age and legal persons who, by committing themselves to the objectives of the Cooperative, are admitted as such by the management can be members. However, it is possible to transmit the titles by endorsement by signing the same titles signed by the transferor and recorded in the record book of the cooperative, once the minor reaches the age of majority according to number 2 of article 23 of the articles of association.

In order to become a member of Coopérnico, you must acquire at least three Coopérnico shares (60 €). You can make the purchase through the Participate menu of this site.
As a member of the Coopérnico you can actively participate in policy-making and decision-making, and you have the right to vote, on an equal footing with all members.You can also participate directly in the renewable projects for the development of a sustainable economy and through this participation receive an interest rate that the said investments will generate, investing in other projects, raising or giving another use to its amortized capital.You will promote sustainable development and a cleaner energy sector and, in addition to being profitable for investment savings, you will also help the environment.
About your bank number, it will only be necessary to fill in this field if you want to invest in our projects. Because we need to know that information in order to pay you back the interest amount and the amortizations in the bank account that you indicate us.
However, it will be mandatory to introduce the NIF field since, when becoming a member, you become the holder of shares of the cooperative's social capital.

Production and investments

The model of project financing used by Coopérnico was based on the existence of a system of subsidized tariffs. Through this model, Coopérnico produces electricity in the solar photovoltaic plants and sells it to the grid, obtaining from it profits that are shared with the members, with the cooperative and with the institutions where the panels are installed. However, it has only be approved by the members that this type of investment is only to be done in rooftops of social solidarity organizations, ONGs and other type of charities and/or cooperatives. Now a days it’s being discussed if the projects should be implemented in rooftops of private companies and if so, what type of companies.
The interest on the capitals applied in the cooperative will be deducted at the rate in force at the time of payment. This rate currently stands at 28%.The payment to investors in Coopérnico projects is made with the partial return of the capital over time, as exemplified in the simulations available on our website, on any project page:
Coopérnico finances its projects through the investment of its members. Members use part of their savings in investments in small renewable energy projects in which each one can own the part that he/she wishes. The minimum amount to invest and investment conditions may vary from project to project. Our goal is for projects to have a return for investors of 3% per year and the minimum amount to invest right now is € 250.
If management is requested to anticipate the reimbursement, the cooperative may proceed to make the totality or fraction of the amount requested available on the secondary market.If there is another cooperating party interested in making available the equivalent amount to reimburse in advance, it may, by written agreement, operate the substitution, without being subject to any penalty and upon payment of interest due up to the date of such reimbursement.
Coopérnico's projects were developed under the legal regime applicable to the production of electricity from renewable resources, through mini-production units, regulated by Decree-Law nº34 / 2011 of 8 March.The miniproduction regime, which has since ceased to exist, allows the sale of all the energy produced to the public service electricity grid (RESP) at a subsidized rate, with a 15-year contract being established for this purpose. This subsidized regime, coupled with the fact that in Portugal the number of hours of solar exposure is very constant and high, makes investments in Coopérnico projects at almost zero risk. Although the legal framework has changed, the contracts signed are honored by the State and the payment of tariffs is assured until the end of them.
The partial return of the capital invested over the investment period is defined according to the investment plan and allows the anticipation of capital and investment in other projects of the Coopérnico or the withdrawal from the same (see in the simulator available on the page of any project:
In order to participate in Coopérnico projects, you must first become a member of our cooperative.

There are many reasons to participate in Coopérnico projects but we highlight the following:
  1. Sustainable investment: investment in renewable energies has economic, environmental and social benefits;
  2. Environmental advantages: investment in renewable energy contributes to combating atmospheric pollution and climate change. It also contributes to reducing the use of fossil fuels;
  3. Social advantages: the projects developed between Coopérnico and social solidarity organizations are also a way of helping them to finance themselves, making use of unused spaces (roofs or vacant lots, for example);
  4. Conscious investment and creation of real value: each investor knows exactly where the capital that he/she decides to invest is being applied on and that it is being used for a positive end;
  5. Partial return of capital invested over the investment period: defined in accordance with the investment plan, allows the anticipation of capital and investment in other projects of Coopérnico or it withdrawal (see the simulator available on the page of any project:;
  6. Attractive interest rate without unexpected commissions: Coopérnico projects have an interesting remuneration compatible with the social and environmental scope of the project;
  7. Investment safety: Coopérnico has experienced professionals in the planning and installation of PV solar modules. Also the number of hours of sun exposure is very constant and predictable;
  8. Strong model: Although Coopérnico is an innovative initiative in Portugal, this is an economic model that has already shown positive results in countries such as Spain, England, Ireland, Belgium, France, Germany, USA, Canada or Denmark;
  9. Promotion of local economy: Coopérnico gives preference to the contracting of Portuguese suppliers and, whenever possible, suppliers from the same places where the projects are implemented;
  10. Portuguese sun: the source of energy used by Coopérnico, until now, is the sun. A resource that Portugal has in abundance and that will help our projects to produce more;
  11. Success of previous projects: Coopérnico has 16 projects in full operation since 2013, some with results above initial projections;
  12. Transparency and integrity: they are pillars of our way of being and functioning. Information on the cooperative and on investment projects is available online at our website.
Coopérnico is naturally interested in the collaboration that promotes the implementation of renewable energy projects, especially in the rooftops of IPSS (ONGs).In order to better evaluate the potential of the proposed projects we need to know some characteristics of the installation sites to better verify the conditions and potential. In order to expedite the process, if you are able to do so, we ask you to send us an electricity bill from the facility where you believe there is potential for electricity production infrastructures and an aerial image (if available). You can write to We will give the best follow-up to your project idea and will contact the person who will best know how to manage the evaluation process and its requirements.

Electricity supply

In order to change the contracted power, there is no associated cost, unless this change implies a change in the phase type. An example of this is the change from Monophasic to Three Phase. If the installation of your dwelling is not prepared for the latter, you’ll need to hire an electrician to do that part.
Coopérnico's members and clients must communicate their electricity meter readings once a month (every 30 days) through their personal area on our website. The delivery period depends on the date of activation of the contract. 
However, we remind you that the meters will be also read by EDP Distribuição at least every two months, as it is obligatory under its concession. 
Regarding the invoices, they may be generated based on estimated amounts in the following cases:

  • The client sends the reading, out of the due period;
  • The readings are not sent by the client. 

Regarding the usual billing cycle, this can be interrupted in the following cases:
  • Visit by the technicians of the Distribution Network Operator (EDP Distribuição) to collect readings;
  • The client sends the reading, out of the due period;
  • Interruptions or changes to the electricity supply contract.
The liberalized energy market translates into free competition in prices and commercial conditions between the different operators. This commercial competition must obey the rules of competition, general laws and the applicable regulations approved by ERSE. 
With the liberalization of the market, all consumers have the right to choose their electricity supplier. 

For more information about the liberalized energy market see the ERSE website

The quality of the service is the responsibility of the Distribution Network Operator (EDP Distribuição) and not Coopérnico. You can contact them on the number 800 506 506.
Coopérnico members can be responsible for the contracts that they want in their own name and can also offer 3 contracts to relatives or friends with the coopérnico tariff.
No. The meter is owned by the distribution network operator and not the energy supplier, so it remains the same. The meter will only be replaced if there is a change in the consumption profile that technically determines the need to replace it.
Yes. If there is no loyalty period, the consumer can change at any time.
No. If you are not happy you can always go back to the regulated market.
The process is very simple: once you are a member of our cooperative (mandatory condition), you only have to fill in the data related to the registration of the electricity supply contract. We'll take care of the rest.In addition to fast and free, the process is simple and does not involve switching the electricity meter. Furthermore, we guarantee that there will be no interruption in the power supply. If you are interested, click on the "Hire" menu on our website.
  • The Coopérnico member number. If you are not already a member of the cooperative, you can become here: Register;
  • The Bank Identification Number (NIB / IBAN / SWIFT);
  • The Citizen's Card;
  • At the end of the registration you will need to upload the signed contract ~(you must sign every page and where it is marked).
Typically, the change of supplier takes between 15 days to 3 weeks. It should be noted that some changes may extend beyond this period if there is a need for intervention at the place of consumption (e.g. change in measuring equipment or extraordinary reading).
If you need further clarification, please contact us by e-mail at or by phone, (+351) 213 471 376.
The meters are the property of the Distribution Network Operator (EDP Distribuição) and it is also the latter that is required to perform quarterly readings, which it subsequently communicates to us. Cooperative members and customers may also (and should) submit meter readings on a monthly basis to avoid estimated invoicing. You can send your monthly readings through the form that we provide in your personal area. Alternatively you can send directly to the Distribution Network Operator.
Coopérnico has prepared a document to help our members read the electricity meter. 

You can consult this document here.
The electricity consumed by our members and customers comes from the wholesale electricity market (OMIE) and it is Coopérnico's responsibility to ensure that our photovoltaic power plants produce enough electricity to compensate the consumption of our members and customers. These energy production projects are funded by voluntary financial contributions from our members. With these projects, we want to cover 100% of the electricity consumed by our members and customers.                                                  

                                                Production> Membership consumption

This is not the case, but if the cooperative projects cannot produce all the electricity consumed by our members and customers, the difference will be complemented by the acquisition of certificates of guarantee of renewable origin. These warranties of origin are acquired at the end of each calendar year when you have information about what the exact total consumption of our members and customers was in that year. Since 2005, the Originating Guarantee Agency (EEGO) was REN. The responsibility for issuing these guarantees was transferred to the DGEG in 2015. The procedure for acquiring these guarantees has not, to date, been defined by the DGEG.
Electricity is supplied using existing transmission and distribution networks, with the cost of transporting the electricity already included in the final consumer bill.
Yes, you can. However, when making your request for a change of energy supplier to Coopérnico you must keep the characteristics of your current contract. You only be able to request changes after receiving confirmation of activation of your contract.


For a correct assessment we suggest that you just ask for an assessment of the potential of your home for self-consumption after it has been habited for at least 3 months, although the ideal period is 12 months of electricity bills.
For a correct sizing, you must send 12 months of electricity bills to the company you choose to supply the systems. It is customary for consumption to be different throughout the year and as such the system has to respond to these variations in the best possible way.
Yes. In a correct assessment, several factors are taken into account:
  1. It is necessary to take into account the type of roof (flat or inclined).
  2. In the case of sloping roofs it is necessary to know its orientation (preferably oriented towards the south).

For example, installation on a sloping, south-facing roof is cheaper than on a flat roof. However if the roof is tilted but not facing south, its installation may have a higher value.
Yes. You can choose to install a system of smaller dimensions to respond to the minimum consumptions you have during the day, which includes appliances such as the refrigerator. However, it is still relevant to send the electricity bills for better sizing of the system.
No. The self-consumption system is able to match the share of its consumption, but it never ceases to be connected to the national electricity grid. The part of your consumption that is not satisfied by the self-consumption system will be purchased from the network. The self-consumption photovoltaic system does not provide power to your home at night and during the day may not provide enough at peak consumption or in periods with or without sun.
The excess of energy produced by your system enters the national electricity grid, but that energy will not be remunerated.

The purpose of the self-consumption system is to respond to the maximum of your consumption during the day. With the legislation in force, it does not financially compensate to sell the (punctual) production surplus to the network.
No. Given the legislation for the production and self-consumption unit, the selling price for energy injected into the grid is so small that it does not become profitable at all. The UPAC (Self-Production Production Unit) is regulated by decree-law No. 153/2014 of 20 October.
Yes. It is a more complex process, which depends on several factors. First, you must ask for permission from the other joint owners. The installation of the self-consumption systems needs to be approved by 51% of the condominium owners, if the installation goes to their home, and approved by 2/3 of the condominium owners, if the system goes to the building.
The feasibility of the installation depends on the structure of the building. We suggest you make a request for evaluation to that effect to at least one company.
Registration must be done with DGEG (Direcção Geral de Energia e Geologia), through the electronic portal of DGEG ( The registration fees depend on the characteristics of the self-consumption unit, such as the installed power and if it intends to inject into the network. The periodic registration and inspection fees are in accordance with the provisions of article 19 of Administrative Rule no. 14/2015 ( details / maximized).
