Europe is increasingly becoming a region with the fastest-growing energy revolution as the community have seized the opportunity to control and produce their renewable energy. Community solar project in Europe is an incredible concept that has levelled the renewable energy playing field for every citizen. Either business owners, groups, NGOs, individuals, and more can build, lease and co-own a solar array of energy. It is an opportunity for even the least earning family or people who rented the home they live in to afford such luxury.
Now, that’s a win-win for everyone.
Impact of Community Solar Projects on EU Energy Goals
A new green energy deal that the EU has just secured will see them become the leader of community solar projects.
The EU has enacted laws that would see citizens build solar projects in their backyard rather than seeking one in faraway towns or foreign countries. The goal is to make millions of citizens in Europe consume the energy they produce.
More so, the EU is hoping to attain their goal of zero-carbon emission by 2050. Large scale development of solar projects would go a long way in achieving this feat.
Although multinational companies will play a vital role in this transition, the community cooperatives will eventually outpace the companies’ contribution making it a centralized and decentralized renewable energy production.
To attain the goal of clean energy, environmental-friendly climate and cost-effective production of renewable energy by 2050, the EU has empowered local producers of solar panels, which would strongly boost the grassroots movement of renewable energy development.
Several communities in different regions in Europe have started replacing their non-renewable energy source with solar projects to power their homes, farms and ranches.
Community Solar Project in Italy
Italy started slowly in the integration of solar community projects, and they are not backing down.
Over 40 households in the Reggio Emilia, Northern Italy Region, are currently testing the installation of the Solar PV projects targeted at social housing. A collective effort of this community will see houses and electric vehicles catered for.
Other areas like Poggio Renatico, the province of Ferrara, will be the first (of many) communities in Italy to have a solar PV farm. However, it has been tipped to have the best solar project technology on the planet. The best part is, it is an initiative that allows the active participation of citizens.
Consequently, the Italian government has seen this as an opportunity to boost the economy after the upturn caused by the COVID-19 pandemic. Therefore, the government has reviewed the renewable energy laws making it possible for citizens to get solar project bonuses in tax-deductible allowance to produce and install solar PV systems.
Community Solar Programs in Germany
The genesis of the solar programs in Germany was quite remarkable. It began with the pioneers of Nuclear-Free Future (NFF) proclaiming the gospel of clean energy.
After the devastating effect of nuclear plants and fossil fuels in the 1980s, the parent members of this initiative went from door to door, sensitizing every German citizen (in Schönau, a rural town in southwest Germany) in the early 1990s on clean energy production.
Over time, the objective came to fruition, and the whole community came together to develop a clean energy source. NFF made this possible through potential government subsidies and information on alternative energy sources.
Schönau rural town went from nuclear power sources to hydroelectric powered systems, supported with photovoltaic (PV) systems in the long run. Thus, EWS (ElektrizitätsWerke Schönau), as it is so-called, is known not only for its promotion of green energy or electricity movement but one of the first pioneers of improving the participation of people and communities in solar programs.
EWS became an energy supplier for solar programs and other clean energy sources in Germany in 1997. Presently, there are over 100,000 customers across Germany purchasing electricity from EWS.
More so, EWS is creating the densest solar power in the whole of Germany. This spread like wildfire, making Germany the world largest solar program facilitator.
Switzerland Community Solar Projects
The primary source of renewable energy in Switzerland is solar energy. The early 1980s saw Switzerland become the first region in Europe to power an electricity network with a photovoltaic system. As a result, the region is known as a master of innovation in solar energy.
Construction of solar projects has evolved in smaller communities have installations are now seen in single-family homes and multi-family homes. This has helped reduce the cost of installations and the development of more PV systems. Now, panels are made with roof coverings and exterior designs.
The Swiss government has made this possible by supporting solar community projects with 30% of the initial cost, and the rest is split amongst the community.
This has given rise to over 80,000 solar projects (PV system) installations generating over 2,000 MW of power – catering for 3.4% of electricity consumption in Switzerland.
Community Solar Projects in France
The largest solar plant in the world, which happen to be a community solar project, is in France. This floating revolutionary solar project is being constructed in the Southern part of France.
The project incorporates a communal dimension where citizens were allowed to have a stake in the project. The primary objective of this approach is to encourage citizens to become involved in the financing of the clean energy transition in France.
This project would power over 4,000 homes and reduce C02 emission into the atmosphere by 11%
How Hivepower Community Manager can Power Your RE Based Projects.
It’s a user-friendly and very interactive platform that has been provided for prosumers and consumers. It reduces any form of loss and improves the management of all stakeholders.
The app provides the perfect summary of your electricity usage time, ranging from the informative summary of electricity usage to insights on local solar energy consumption and cost savings.
The best part, you’ll be notified about any form of abnormalities automatically anything that is detected.
Community solar projects permit everybody to profit from solar energy, whether they can or cannot put panels on a housetop.
In regions where solar power is more affordable than customarily created power, buyers can get a good deal on their month to month bills.
If supporters move to another home inside a similar utility assistance region or province, they can normally keep on profiting from their local area solar timeshare.
Just as the progress of a being shows its life, the growth in a nation shows that it has great abilities. Europe, for one, has shown immense growth in the past three to four years alone. Following act 21 of the RED II (Renewable Energy Directive II), efforts have been made to bring Europe to its target for renewable energy by various bodies.
Interestingly, the statistics of the energy economy in the European Union (EU) show an increase in the production of renewable energy. In 2019, it had the biggest share in primary energy production (36.5%) and so looks productive. As more renewable energy projects come up, more technologies come up to keep up.
More so, to achieve the factors on which sustenance energy thrives (energy security, environmental impact mitigation, and social equity), some ways of keeping sustainable energy effective have come up. One of the most effective is energy communities.
In the same way projects in the US like the Butler solar facility, Comanche solar, and the rest are making progress, Europe is maximizing sustainable energy by doing more energy projects. Energy communities in Europe are increasingly helping citizens contribute to renewable energy and see the effect as closely as possible.
One important thing that characterizes energy communities is citizens’ collective and organized action in producing and using sustainable energy. There are some projects currently going on in Europe whose influence is turning the energy sector around. You can find five top ones here, which we will discuss.
1. The Lugaggia Innovation Community (LIC) Project
The Institute of Systems and Applied Electronics (SUPSI) launched a project in 2019, which is gradually coming to completion in 2021. This project, the Lugaggia Innovation Community, was set up as a self-consumption community. After the municipality of Capriasca installed a solar photovoltaic plant on the roof of a kindergarten, users observed that the rate of consumption of this power was low. To maximize the energy, the LIC connects the kindergarten with ten nearby houses.
The technologies applied in LIC are of utmost importance as they apply key advancements. Two technical solutions provide the backbone of the LIC project – a centralized platform for energy management provided by Optimatik and a decentralized control system by Hive Power’s control module. This second solution introduces blockchain technology for a versatile application. The control that it provides caters to synchronization, payments, sensing, and actuation.
The LIC project is a strong one as it was initially experimental but now promises to be an innovation site. Processes are in place to make it as efficient as possible.
This project is being carried out in Zwevegem, a small town in West Flanders, Belgium. RE/SOURCED stands for Renewable Energy Solutions for Urban communities based on Circular Economy policies and DC backbones. It is focused on maximizing sustainable energy, conversion of heritage, and the circular economy.
There are three structural partners to the RE/SOURCED project, namely:
- the Province West-Flanders, and
With these three partners, the project is led by the intercommunale Leiedal and supported by Urban Innovation Actions of the EU. The project aims at transforming a former power station (established in 1912), Transfo, into an energy community.
Transfo is now a multifunctional site with homes, offices and other structures. It is a 10-hectare site preserved for its heritage and with a lot of significance. The citizens of this community are to benefit from the local power grid that is being developed. The focus is currently on making circularity applicable in renewable energy.
The DC grid for the RE/SOURCED project brings together various renewable energy sources – wind turbines, solar panels, and storage facilities. The idea of a circular economy comes into play in using more efficient materials for the demand of steel, copper, lithium, and the like to be met. The factor of material usage is great in the sustainability of energy systems.
With a focus on energy islands, the COMPILE project started in 2018 and is actively in progress. It is centred around the decarbonization of the energy supply process and community building.
There are up to twelve (12) partners in this project, and they all play roles in putting it together. The project has received funding from the European Union’s horizon 2020 research and innovation. It promises to make use of some tools to achieve its goals.
- COOLkit – this combines the elements of COMPILE’s toolset. All of this is for proper management of the energy community by communicating methods, motives and steps.
- GridRule – this tool is to help actors in the project know how to manage and control a microgrid.
- EVrule – for electric vehicle charging, an electrical charging station by Etrel is explored. This allows for a fair distribution of available power for charging.
- HomeRule – this platform allows users to understand the consumption of power and storage. It is connected with the EVrule and ComPilot.
- ComPilot – this tool is a digital platform. It would provide a stage for virtual social energy communities and work with the other tools.
- Value tool – helps consumers or communities that want to start or join the energy community. The tool provides various business models for these prospective users to explore.
4. The SCCALE 20-30-50 project
Scaling up, according to the project’s name, is a major focus of this project. It kicked off on the 7th of June, 2021, aiming to bring Europe closer to the renewable energy goals. RESCoop coordinates it. There are partners from 5 countries – Energy Cities member cities Leuven (Belgium) and Poreč (Croatia), the energy cooperatives Enercoop, Electra, Energie Samen, ZEZ and Ecopower and TU Delft.
The synergy among the technologies of these partners is on the move to power energy communities around Europe. It is set to create 25 energy communities and 34 community projects.
This project seeks to empower prosumers and create a platform where all can play a good role in the energy market. It is a project that is still under development and plans to be demonstrated in 4 countries on a large scale – Italy, Belgium, Spain and Greece.
WiseGRID integrates ICT systems in the distribution grids of energy to ensure flexibility of the grid systems. A set of technologies will be put in place to ensure smarter grids. The use of enhanced storage systems (batteries and heat accumulators) is a special highlight that WiseGRID will use to store energy from renewable sources.
Also, virtual power plants would be used to manage the controls in this project. Of the 21 partners in this project, several include Ampere Energy, ReScoop, Eco power, and so on.
Power generation, distribution, and control are critical anywhere in the world. Interestingly, the more we improve at anything, the more work we have to do. Catherine Pulsifer once made a quote on implied consequences – Life presents many choices, and the choices we make will determine our future. Therefore, as many as choose to solve the problems of energy sustainability must plan to take responsibility for the coordination it requires, even at the communities level.
The Problems LIC (Energy Communities) Solves
One particular sustainable energy source that is very reliable is the use of solar photovoltaic systems. The power supplied by the sun is more than any other source. However, various problems arise from solar power generation using photovoltaic systems.
- Operational challenges – the nature of solar production can be random. This is due to changing intensities of radiation from the sun. The photovoltaic cell produces the appropriate electrical energy each time, but the nonlinear state gives technical issues.
- Overloading of grid components – the produced voltage may not be consumed at the normal rate. This may cause overvoltage in the grids.
- High cost of self-generation – attempting to get power for independent use is expensive. Not only is it expensive, but it also is not profitable for distribution companies and operators.
Most of these problems are solved with the use of smart grids. Smart grids may be complex, but they allow for more efficient energy systems. They make use of technology to improve the communication, automation, and connectivity of power networks. The regulation is also very useful – when less power is consumed, production is reduced.
Also, when power production approaches its peak, there is an automatic regulation. The automation of the distribution process makes it easier to control and maximize the power generated. We minimize losses as a result.
How LIC works
To solve these issues in the public grid for the village of Lugaggia, LIC was set up. The Lugaggia Innovation Community (LIC) by the University of Applied Sciences and Arts of Southern Switzerland (SUPSI) is an excellent step in the right direction. It is a community set-up that aims at onboarding house owners and the kindergarten around them to a smart grid.
Objectives of this project include:
- checking how acceptable the self-consumption communities would be to the community stakeholders
- making use of blockchain to decentralize the management of bills
- evaluating the needs and requirements of the practical LIC
- accessing the potential for local flexibility
- technically observing the effect of flexibility and how it can be exploited.
In order to reduce grid issues, in terms of unbalances encountered in the distribution grid and the accompanying tariffs and taxes, grids have been handled by this LIC. Starting from creating the self-consumption community (SCC), LIC meets the entire community’s pertinent energy needs. It is in line with all the energy ordinances and laws guiding SCCs. It is not enough to produce power; there is more need to get it to where it is needed and for it to be cost-effective.
The Approach LIC Takes
LIC’s resources consist of homes powered by solar panels and their installations (heat pumps and heaters). They are all first centralized using the OptiFlex-Innosuisse (a product by Optimatik, a Swiss Smart Grid solution provider) solution. This is by integrating all outlets in one grid and making use of a district battery. Once this is done, Hive Power comes in to play a vital role.
Decentralized energy management in LIC is done by implementing our community manager module on the Hive Platform. LIC requires this module to achieve a more flexible control. By the use of blockchain technology, the entire process is secured. These processes include sensing, actuation, synchronization, and even payments.
Major Contribution by Hive Power
Grid managers can easily assess all details and overview of the generation and consumption of power in the LIC project using the Hive Power Core Module. Appropriate measurement of energy and monetization is as well performed adequately with the Hive Platform. Once the value is known, it is sent to the blockchain.
The community got operational on October 1st, 2019, and had been experimented on. Some major milestones have been met, but overall, the LIC project has reached the halfway milestone.
Some of the blockchain activities have been set off. LIC has already gotten a second-layer solution using sidechain technology. This solution was developed, implemented, and tested in the LIC in 2020.
Also, the capability to preserve the prosumers’ privacy has been seen to be useful. A dedicated technology (Auditable Tariff – AT) runs at intervals and stores data about the production and consumption of energy on the sidechain.
The goals of the halfway longitudinal study were majorly to examine pilot activities from the users’ point of view and to evaluate attitudinal changes during the activities. In the end, it was seen that there were no major changes when a survey was taken. This survey was taken twice, at the beginning of October 2019 and recently in December 2020. More particularly, the observed effect of the Lugaggia SCC remained stable.
Current Activities on LIC
Tests on electrical water heaters defined as Domestic Hot Water (DHW) and Heat Pumps are currently ongoing. This is to follow up on the actuation tests on the flexibility done in the last part of 2020.
Also, the current work in the LIC is focused on the adaptation of the industrial version of the OptiFlex solution. It is ongoing and will continue till July.
Considering that this is the last year for the LIC project, the plan has been to focus on the industrialized version of the solution given by OptiFlex. That is, the device to be used for centralization. From August till the end of the year, we will be testing an improved version of the algorithm of decentralization. Further tests on the DHWs would also be conducted with more controlled devices.
The LIC is also participating in the PARITY H2020 project, whose trials would begin in 2022. The project would address issues in existing distribution grids. The efficiency promises to be improved.
The approach provided by Hive Power’s solution (decentralized control) would also be extended and utilized in various business and regulatory environments.
Let’s start with a defining statement for microgrid systems; they are self-sufficient energy systems that cater to energy needs for a small geographical area, they can have one or more kinds of energy sources such as solar panels, heat sources or wind turbines and even contain an energy storage solution, for example, batteries.
Their primary purpose is to produce sustainable power for an allocated area. These areas can be hospitals, campuses, business centres and small neighbourhoods. Microgrid systems are discussed in association with renewable energy, mainly because that is the type of energy being developed in recent years. They happen to do better than large scale grids that cater to larger populations from fossil fuel sources and are becoming increasingly accepted.
Microgrids work in an interconnected way, providing energy to buildings in the form of electricity, cooling and heating through software and digital control systems. Its major characteristics include:
- being local, which means it provides its services to nearby customers
- being independent, which means it can be disconnected from its central grid yet still function at 100%, this comes in handy in times of central outages and lastly
- being intelligent, which is a result of advanced software and management systems.
With the efficiency of microgrids, there is a pertinent need to measure their energy demand and supply, which is where Demand-Side Management comes in.
What is Demand-Side Management (DSM)?
Demand-Side Management can be explained as the “group of actions designed to efficiently manage a site’s energy consumption to cut costs incurred for the supply of electrical energy, from grid charges and general system charges, including taxes” according to Enel X. These actions are necessary for optimising energy use and saving costs on electricity charges by understanding the overall consumption costs, the amount of time this consumption occurs, and the supply and connection parameters.
Demand-Side Management is enshrined in the instability of grid systems around the world since renewable energy sources are highly penetrable including the decentralisation of their production, these cause innumerable disruptions on the microgrids and grid management services, a balance is therefore needed.
The demand and supply balance is a significant worry; the amount of energy created and fed into the grids has to match the consumption habits. Grid managers can now create energy management systems to offer grid services that are paid for, which in turn increase the costs for the electrical system.
In-depth on-site analysis has to be carried out on individual microgrid sites to properly engage in Demand-Side Management to ascertain the generation and consumption habits of customers.
All the measures used under Demand-Side Management are implemented on the generation side of the energy meter to modify consumption patterns and enable efficiency in using and managing energy loads. The measures don’t only involve energy efficiency but also something else called Demand Response (DR).
Demand Response is a technique that microgrid managers use to balance out sudden surges or plummets in consumers’ consumption of energy. DSM program participation, for now, can be voluntary or mandatory for consumers, for those that decide to volunteer, there are attractive incentives to encourage more participation. Some regulations have been introduced by most energy (electricity specifically) regulators that have encouraged the integration of Demand-Side Management at their facilities, an attempt at a level playing field for DSM.
What are the Advantages of DSM?
As referenced earlier, the major advantage of Demand-Side Management is saving and reducing unnecessary energy losses. These are the direct benefits. The indirect benefits include reducing the frequency of blackouts and the mitigation of emergencies that have to do with the energy systems.
To understand the advantages and disadvantages of DSM, it is imperative to compare it to other alternatives (Supply-Side Alternatives) such as energy generated via renewable energy, the power generated via fossil fuels, load shedding and peak power plants. It is imperative to note that Supply-Side Management deals with energy management on the other side of the meter regarding supply, the polar opposite of DSM.

Here is a comparison of DSM’s advantages from the consumers’ perspective (customers and society) and power utilities. Source: Science Direct
|Reduced cost of operations||Energy bills are reduced due to energy-efficient equipment.||Greenhouse gasses reduction because fossil fuel power plant constructions aren’t needed|
|Reduced expenses on building power plants, costs of transmission and distribution||Power cuts are reduced, and the power supply is more reliable and stable.||Power distribution is equitable due to less disruption of power|
|Operations run efficiently||Customer satisfaction and reduced maintenance costs for energy-efficient appliances||The promotion and development of sustainable energy and efficiency in the conversion of renewable energy sources|
Demand-Side Management with Microgrids allows grid managers to observe how both systems perform in the transformation of conventional microgrids to those that run on renewable energy and how the Management of demand-side can help with the instability of renewable energy sources; how they can work with renewable energy storage systems and how they can be improved on for efficient utilisation and consumption by customers. Our Community Manager module is integrated with blockchain technology that can enable you to utilise DMS effectively and efficiently.
Solar power leads the way as the most popular form of renewable energy in the European Market. With a 36% increase in installations from 2017 to 2018, the adoption of solar technology is on the rise. This trend can be attributed to the drive to meet the EU 2020 targets.
EU 2020 Renewable Energy Directive
In 2009, the EU states set targets to generate at least 20% of their energy from renewable energy by 2020. In this move, the EU defined various support schemes for member countries to cooperate in achieving their targets.
The Cooperation Mechanism is one of the EU 2020 support schemes. It employs three approaches to help members meet the Renewable Energy targets. These include;
- Joint Projects
- Joint Support Schemes
- Statistical Transfers
- The Joint Projects mechanism allows two or more EU countries to co-fund a renewable energy project. They can then share the power generated.
- The Joint Support Scheme mechanism involves the development of schemes such as a common feed-in-tariff. The programme would promote the production of renewables in two or more EU countries.
- Statistical Transfers were designed to level the playing field. Naturally, renewable energy resources are not equally distributed across Europe. As such, member states can buy shares of a renewable project from a resource-rich country. The energy shares are deducted from the producing country and added to the supporting country’s energy portfolio.
These cooperation mechanisms are deployed on a macro level. They involve major policymakers, national energy regulation, transmission companies and energy producers. The concept of working together to meet renewable energy targets has trickled down to the community level. Here, Energy Communities have been formed to help regular citizens to own a share of a solar energy project.
Regulatory Victory for Energy Communities
Following the Paris Agreement, the EU began reviewing its energy policy framework. This framework would facilitate Europe’s transition to low-carbon clean energy. Between 2016 and 2019, the EU developed and refined the Clean Energy for all Europeans Package.
The Clean Energy Package contains specific elements that promote the rights of energy consumers. The new regulations support the generation, storage and sale of energy by individuals. They are especially beneficial for the growth of energy communities in Europe.
What is A Solar Energy Community?
Energy communities are societies that come together and pool resources for the co-ownership of solar energy projects. They can be made up of individuals, small businesses, companies, municipalities and cooperatives, among others. They allow average people to own a share of a solar energy plant.
People mainly join energy communities to reduce their utility bills. They are also interested in participating in the renewable energy revolution. As individuals, most energy community members face several limitations to build solar projects. These include lack of capital, space and property.
Many participants of energy communities live in rental homes. As such, they cannot install home solar panels or benefit from the incentives of solar affords homeowners.
How Do Energy Communities Work?
Energy communities can be structured in various ways depending on the region’s regulatory landscape. In some cases, the community members live near the project site. These members can consume the energy generated directly, which is the typical setup in off-grid locations characterized by mini-grids.
However, in most parts of Europe and North America, an extensive grid network is already established. Here, energy communities can finance new grid-connected solar power plants. Members then earn net metering or solar credits, and they can use these credits to reduce their monthly utility bills based on the amount of electricity generated and the member’s share in the energy community.
Solar is attractive for energy communities because it is a low-cost solution that is scalable and readily available. The communities calculate their solar credits through a Virtual Net Metering (VNM) system. The VNM enables you to earn Net Metering Credits from a solar energy system that you didn’t connect to. As long as your grid provider buys the energy generated by the solar plant, you can earn Net Metering Credits.
Are Energy Communities Good For Solar Projects?
Energy communities create an avenue for new players to participate in the transition to clean energy. The European housing statistics indicate that approximately 42% of Europeans lived in apartment blocks in 2017. Meaning that, regardless of financial capacity, almost half the population don’t own roofs to install rooftop solar projects.
Through energy communities, people who were conventionally left out can now acquire solar energy assets. Here are various ways in which the energy communities can lead to higher solar sales.
Faster Transition to Clean Energy
Unlike the conventional solar home system format, energy communities support a more active uptake of solar energy. Energy communities connect multiple customers per project. While the power generated may not be for direct self-consumption, each member of the community has a share in it.
As you approach utility-scale, solar energy community projects have the advantage of quick adoption. These systems acquire land rights and social acceptance much faster than typical utility-scale solar projects. This pattern is because most of the decision-makers in the community have a stake in the project. The energy community members are usually well informed about the project, allowing the developers to focus on the implementation of the project rather than gaining social acceptance.
Overcomes Grid Limitations
In remote or rural settings, the national grid may not reach every potential customer. The cost of grid expansion is also high. Also, the challenges of upgrading weak networks for demand-side management can limit the connectivity of new projects.
Energy communities can employ smart mini-grids to connect consumers. This step avoids straining the existing grid system. The mini-grids can also connect and feed solar power to the grid directly. High-quality mini-grids with adequate net metering infrastructure reduce losses and maximize the revenue for grid-connected solar projects.
Improved Energy Storage Management
It is challenging to ensure the uninterrupted supply of electricity on the national grid. Energy communities can facilitate Community Energy Storage (CES) solutions. Collective energy storage solutions are easier to manage and maintain than in individual homes.
Energy storage is a vital component of solar energy systems, and they reduce the load and reliance on the grid at night while community solar plants with integrated energy storage provide well-balanced uninterrupted power supply options.
Cost-Effective Solar Solutions
Energy communities enable more people to overcome the investment barriers involved with solar energy projects. The high initial investment costs are among the most significant obstacles to the integration of solar projects.
Energy communities allow members to share the cost of developing a solar project. This action lowers the entry cost for each individual and makes the project more attractive.
Development of Smart Grid Technology Markets
The new EU energy policy encourages the development of decentralized energy generation. In the past, independent power producers were either small individual homes or utility-scale solar projects. Energy communities create a demand for innovative smart technologies in the solar energy space.
Energy communities need dynamic digitized solutions to monitor their solar power systems. These solutions are necessary for data analysis, system optimization and report generation for the energy community members. Advanced analytical solutions are also required for net-metered systems that generate solar credits for the community’s shareholders.
The deployment of energy communities creates an opportunity for unmatched growth of solar energy in Europe. Enabling people who live in flats to participate and co-own solar projects almost doubles the potential solar investors in the EU. Integration of energy communities can accelerate the efficient development of solar projects across Europe.
