The Investment Concept will be focused on energy optimisation in Bottrop Fuhlenbrock/ Vonderort in order to identify the efficiency potential in the district, and then develop clear projects that can be financed. This is because a grouping of small-scale projects can generate synergy effects and cost savings by combining the purchase of materials and the handling of refurbishment, building insulation and heating replacement. A “financing by citizens” programme can create an additional benefit for (private) investors through the contribution to energy upgrades and climate resilience in the home


The technology measures to be financed include LED-lighting, heat pumps, low-carbon heat grids, photovoltaic systems, solar thermal systems, access to local renewable heat sources (e.g. geothermal drilling) and charging stations for electric vehicles and bicycles. All of these technologies shall be used in a way that is compatible with the European Investment Bank (EIB) eligibility criteria.


The aim of the investment concept is to expand the solar energy production in the region of Rostock, expanding solar parks, photovoltaic and solar thermal plants in open space.

After making an inventory of the (needed) adjustments and engineering analysis, an investment plan is drawn up. This creates clarity regarding the financial feasibility of switching from individual central heating boilers in residential buildings to sustainable district heating. To achieve this, adjustments to the public space (infrastructure) and adjustments to the residential buildings will be made. The latter will be done through consultation with the owners/citizens. The residential buildings are located in two different districts in the municipality of Purmerend and Beemster. In Middenbeemster (municipality of Beemster), approximately 600 houses need to be inspected to draw up an investment plan. Before this, 470 houses need to be inspected in the second district, Overwhere- Zuid (municipality Purmerend).


In the city of Berkelland, the EUCF grant will be used to assess the possibility of ESCOs as a solution to reduce energy consumption in the housing sector. The project mainly focuses on the needs and demands of the dwellers, and this may differ per area or house. Increasing energy standards needs to coincide with an increase of comfort, healthy living programmes, poverty reduction and generation-proof housing. Making business cases viable, while safeguarding the freedom of choice for the residents regarding the degree to which they would like to be unburdened and supported by the ESCO.


Intended measures comprise the establishment of the EHB to provide heat to one part of the city Breda. The technical scope includes:

  • Heat source extraction WWTP
  • Central system, large scale, high temperature heat pump
  • Tracker based solar-PV to increase sustainability of project (electricity supply)
  • Internal heat network system to connect several systems
  • External heat network system to connect with main heat network Breda
  • High temperature, seasonal, underground storage and daily storage/buffer
  • E-boiler with smart interaction electricity grid
  • Smart digital controls irt WWTP
  • Electricity connection
  • Pumps, filters, civil works
  • Monitoring and control systems


In Bronckhorst, the creation of an ESCO will reduce energy consumption and, if convenient, implement heat and renewable energy solutions. It will focus on the renovation of housing to a higher energy standard: isolation, restoration, and it may include integrating renewables (e.g. solar panels) and the heating system as an integral part of the energy system of residential and public buildings, or buildings
for small businesses. In the investment concept so-called ‘linkage opportunities’ regarding the public space, traffic, circularity, climate adaptation, and biodiversity will also be considered.


Bunnik will use the EUCF grant to produce an investment concept that focuses in increasing energy standards of residential buildings via, primarily, rooftops restoration and installation of solar panel. The creation of an ESCO will be explored to enable such actions, ensuring energy consumption reduction and the implementation of heat and renewable energy solutions.

De Bilt

In the Bilt, an ESCO will aim at reducing energy consumption and, if possible, implement heat and renewable energy solutions. The investment concept, developed within the EUCF, will focus on the renovation of housing to a higher energy standard and may include integrating renewables and the heating system as an integral part of the energy system of residential and public buildings, or buildings for small businesses.

Gemeente Ede    

Creation of a regional development fund for a local and regional production of sustainable energy (wind and solar) that will have a 50% of local ownership and management by citizens. International cooperation with partners in the Global South with programmes on climate mitigation and adaptation will be explored. The fund will be created by putting a levy on electricity and natural gas consumption by all actors providing public services in the municipalities of the region involved, which represent 9-10% of the energy consumption of the region. The levies will replace the currently Guarantees of Origin and CO2 offsetting. The Development Fund aims to target the public service sector with near 100% sustainable energy coverage by 2030/2035.

Horst aan de Maas

Intended measures to be financed include the replacing the use of natural gas for cooking and heating with sustainable electric alternatives, installation of heat pump, upgrading the energy efficiency of buildings to level B (preferably A) and installing more solar panels on roofs. Targeted sectors include Public buildings, building integrated renewables, Residential buildings and Innovative energy infrastructure.


This investment concept was part of Call 5. 


In Epe, through a pilot in Oene, the investment concept will focus on how an ESCO can facilitate CO2 neutrality, in a collective manner in energy communities with affordable measures. The focus of the ESCO is to reduce energy consumption and implement heat and renewable energy solutions. As part of the larger network, the knowledge centre, the possibility of innovative energy infrastructure, like 5th generation heating concepts is included. The intended technology measures are: Integrating renewables (e.g. solar panels), Isolation, restoration and lastly, a heating system as an integral part of the energy system of residential and public buildings, or buildings for small businesses.


The project will proceed in many phases. For phase 1, residual heat from two data centres on the nearby Zernike Campus will be used as heat sources. Solar heating collectors (Dorkwerd) will also provide heat. For the next phases, residual heat from Solidus (the company producing fibre-based packaging) and Cosun Beet Company (sugar beet processor), located in Hoogkerk, are studied as heat sources. On a regional scale, more potential residual heat sources are available from the industry in Delfzijl/Eemshaven. The feasibility of these potential heat sources is also currently studied.

The city will continue to monitor developments of other potential future heat sources, including low local temperature sources, such as aqua thermal or ground source heat/residual heat from local businesses, as well as geothermal energy. The market for heat sources is dynamic. This requires maximum flexibility. In phase 1, the decision is to construct a network that can handle high temperatures (90 °C). This reduces the costs and disruption in case a change of heat source is made in the future.


The focus of this project is PV technologies. Regular large-scale PV systems require roof reinforcement measures to strengthen the bearing capacity. This problem mainly concerns large utility buildings. Because of the additional costs, the business case becomes less profitable, and the PVs are not purchased. Therefore, this investment concept promotes the use of innovative lightweight solar panels. Since the panels are lighter, reinforcement is not necessary. Hence, the technical feasibility study.

In the solar park projects, they endorse PV systems that benefit landscape integration and soil quality. For example, regular PV lets less light through, which in turn causes soil degradation. New bi-facial PV panels overcome this problem by not having a dark back panel on which the solar cells are placed. Instead, it contains glass on both sides and captures the light that passes through the back panel. As a result, the power output is significantly higher, and the soil quality is maintained.


The focus here is on energy savings and also to find and implement heat and renewable energy solutions. A collective approach for investments leads to different business concepts and technical solutions. For residential areas, there is no ESCO willing to take the whole neighbourhood as a target area. Natural gas is phased out, and district heating might be a solution, depending on the level of isolation and renewable heat supply. What fits best is under research, and the resulting investment concept includes the entire energy value chain.


The increasing amount of renewable energy projects is causing overcapacity on the energy grid, risking grid malfunction. The municipality of Leeuwarden is one of the first in The Netherlands where grid challenges are causing a delay in the transition towards sustainable energy production and the development of new SMEs, specifically in Business Park De Zwette. Various business owners have shown interest in becoming sustainable, but the local grid capacity is an obstacle.

A communally-owned energy storage solution in which decentralized renewable energy generation can be stored locally to mitigate grid scarcity on De Zwette can therefore accelerate the local energy transition. Several potential technical solutions are envisaged, such as an aqua battery, variable energy storage in the vehicle fleet and /or different methods of battery. The project will identify which solution is most fitting based on the local technical, legal and financial framework.


The investment project focuses on renovation of housing to a higher energy standard: isolation, restoration, and it may include integrating renewables (e.g. solar panels) and the heating system as an integral part of the energy system of residential and public buildings, or buildings for small businesses.


Several analyses in 2021 (for the Transitievisie Warmte) have shown that for the township, heat pump systems are the best option for 84% of the (existing) houses (ca. 21,000 houses) towards fossil-free heating. In the ‘Transitievisie Warmte’, three scenarios of heating were calculated for three different types of houses. This is the first indication of the needed measures and costs. On average, it can be said that the following measures are needed towards making households fossil-free: insulation, heat pumps, radiators (or underfloor heating), induction cookers and ventilation.

Uithoorn (Grouping)    

Intended measures comprise the establishment of a heating grid of approximately 30 km between the greenhouse clusters in Greenport Aalsmeer, including ‘T’ sections where local heat sources and residential neighbourhoods and business parks can collectively connect to the grid. The technical scope includes a 30 km heating grid including T-sections. In addition, there will be a connection to the Greenhouse heating system of up to 300 hectares of greenhouses, including heat exchanger units. They also plan a connection to geothermal heating projects in the greenhouse area’s PrimA4a and De Kwakel-Kudelstaar. They also foresee, within the investment, monitoring and control systems, installation and commissioning and development costs such as engineering, contracting and permits. The development of geothermal wells (PrimA4a and Kudelstaart) is expected in the area but is not included in the scope of this investment concept.

Utrechtse Helvelrug

Utrecht will focus on residential buildings and their energy consumption in the 70s neighbourhood of De Hofjes. The activities will support the ageing population in improving their homes, especially where the financial possibilities are low. Focusing on energy savings will make the neighbourhood ready for an alternative heating system based on renewable energy. The ageing population creates financing challenges for which an innovative investment construct is needed. The solution of an ESCO will be investigated with particular attention to the governance structure.


In Voorst, the investment concept will assess the possibility of ESCOs that may enable a CO2 free Wilp, focusing on energy efficiency in housing and building integrated renewables. The work will, at first, focus on Wilp as a pilot, the resulting construction will be available for the whole of municipality of Voorst. The grant will allow the supporting of a social infrastructure for an energy community, design an institutional framework and build a collective business case for an ESCO.


The investment concept aims to develop the Smart port Waalwijk including EV shipping, EV trucking, charging stations, battery storage and sustainable terminal. The sectors targeted will be building integrated renewables, Sustainable urban mobility, Innovative energy infrastructure and Smart Grids.


Wageningen will use the support of the EUCF to develop an investment concept aiming at reducing energy consumption in the housing sector and explore the possibility to implement heat and renewable energy solutions. An ESCO will work to increase the energy standard of housing: isolation, restoration, and may include integrating renewables such as solar panels.


Measures to be financed include creating a regional 5th generation heat system covering the entire municipality, connecting the various heat clusters with each other and with customers (greenhouse horticulture and the built environment) by building a pipe network and an intelligent dynamic supply-demand parity operating system. In terms of sectors, those targeted are district heating, Innovative energy infrastructure and Smart Grids.


The focus of the ESCo is to reduce energy consumption and, if convenient, implement heat and renewable energy solutions. The project focuses on the renovation of housing to a higher energy standard: insulation, and restoration, and it may include integrating renewables (e.g. solar panels) and the heating system as an integral part of the energy system of residential buildings, or buildings for small businesses.

The research mainly focuses on the needs and demands of the dwellers, as they may differ per area or house. An ESCo should be accepted as a solution by residents and therefore be able to meet their needs. Increasing energy standards coincides with an increase in comfort, healthy living programmes, poverty reduction and generation-proof housing, making business cases viable. In Austerlitz (a village in Zeist) as a pilot, a particular focus is on generation-proof housing, as many of the residents are elderly people.

    The short term goal is to realise renovation of the dwellings/buildings and implement district heating in a specific neighbourhood between IVBO and the city centre. This project will be an absolute game changer in people’s minds and will be used to accelerate the development of a heating network in 4 clusters in city centre after renovation (long term): a city with a lot of UNESCO heritage, small streets, full underground, a lot of worker’s houses, city and public buildings which are badly insulate. In the short term, part of Christus Koning, a neighbourhood of 19th and beginning of the 20th century with  (and a surface of 101,1ha), will be targeted. Apart from private dwellings, there is a swimming pool, two school buildings, supermarket, fitness centre, building of the national employment office and a lot of small retailers. In this way the city shows the good example, showcasing that heat net developed in historic densely built areas are also possible.

    Intercommunale Leiedal

    The project is about 5th generation, low-temperature district heating & cooling (5GDHC), fed with heat from riothermia (the process of recovering heat from sewage waters). The project foresees the development of district heating pipes from the sewage water plant to the city of Menen and, within the city, a 2-pipe system with insulated pipes and delta T of 20 °C due to upgrading the temperature at the sewage water plant with a central heat pump. It also foresees heat pump systems to upgrade from very low temperature to useable heat (regime of 65/45 °C). There will be a heat exchanger to extract heat from effluent water and adapted heating systems of end-users, including individual heating concepts and systems of the end-users (buildings), to connect to 5GDHC, including booster heat pumps in buildings. Key elements are also energy efficiency measures in the buildings of end-users, to reduce heat demand and peak demand by 20%.  The engagement of ESCO is also planned to unburden the end-users.

    This investment Concept was part of Call 5. 


    The project targets low energy retrofits of existing, co-owned condominiums. Currently, there are 16 371 flat units (39% of the residential building stock in Mechelen), of which 11 600 (71%) are built before 1990. This corresponds to approx. 1 600 existing condominiums with poor energy performance. The intended energy efficiency measures concern no-regret measures (roof insulation, high-performance windows with double glazing, facade insulation) as well as the refurbishment of the heating system. Additionally, the goal is to maximise the renewable energy production on the more recent condominium rooftops, by sharing renewable energy between co-owners via energy communities.


    The city of Mortsel has ambitions to lower its CO2-emissions of building heating by applying alternatives for fossil heating such as citizen owned DHN on waste and renewable heat. Therefor it supported the district heating grid operator Warmte Verzilverd to build and operate their DHN using industrial waste heat from an industrial site in Mortsel. At the moment, only a part of the capacity of the heat source is utilized. It is estimated that there is additional capacity of at least 5000 MWh of heat per year (this equals the annual energy consumption for heating of about 350 households). The heat is captured from the chimney of high temperature processes and would otherwise be dissipated in the air. To expand the DHN further investments in distribution infrastructure (piping, pumps, satellite units, …) are needed.

    The investment concept targets major energy renovation of public buildings, mainly administrative offices, municipal schools and sport facilities through retrofitting of HVAC installations with advanced regulation, relighting/re-lamping, renewable energy (heat pump, water solar heating, PV), envelope insulation, smart metering and monitoring of energy efficiency, possibly using the IPMVP protocol.

    Vallée Haute Meuse (Grouping)

    The objective is to finance the creation of solar-power electricity production sites, by way of photovoltaic panels. The precise technology used may vary depending on technical studies for each site. Depending on technical data, the electricity produced could be self-consumed, injected into the network or stocked in batteries. Where applicable, higher panel structures might be needed (above roads, parking lots …). Some sites might be used directly to provide power for electrical vehicle charging stations.


    The municipality of Ranst wants to lower its CO2 emissions by replacing the current heat source (natural gas) with a sustainable alternative: a citizen-owned district heating network based on aqua thermal and waste energy. The project area consists of the centre of Oelegem (sub municipality of Ranst) and the business park Ter Straten. Two separate networks will be installed: the North network, delivering heat to the centre of Oelegem, and the South Network, delivering heat to the business park. The North Network consists of 900 meters of piping and can deliver heat to 120 buildings, of which the majority are individual houses. The source of heating will be a large-scale heat pump using surface water from the canal as its heat source.
    The South Network consists of a 2000-meter network and can deliver heat to 30 industrial buildings. The source of heating will be either a large-scale aqua thermal heat pump or waste energy from a large chemical plant in the business park, or a combination of both.


    This investment concept was part of Call 5. 


    The City of Zottegem aims to obtain a zero energy public building stock by 2050 (and to -55% CO2 emissions by 2030). To this end, their 37 buildings, ranging from office buildings to public meeting centres for inhabitants, a residential care centre, schools and sports facilities, need to be insulated (including window replacement) and their building installations need to be replaced by efficient non-fossil ones. The engineering analysis of this project will uncover the required measures for each of the buildings. The financial analysis will reveal how these measures can be financed. A timeline will be set up, specifying which measure needs to be implemented in which year and the annual budget the city has to foresee.

    Le Havre Seine

    The project is about developing renewable energy production from photovoltaic power plants. This is fully in line with the EIB lending policy, which supports power generation and will give priority to investments that improve the flexibility of networks.

    In addition to reducing the carbon footprint of the city and raising awareness on carbon neutrality objectives, the project will provide flexibility to the local electricity distribution network. The development of solar power plants allows the:
    - Reconfiguration of the electricity distribution network, by
    positioning the power plants at strategic points (in areas
    where consumption will increase) and
    - Smoothing out demands and consumption on the network
    by storing the energy produced and releasing it at consumption peaks.


    The investment concept in Lille aims to deploy a deep renovation model of industrial revolution houses in Northern Europe (“1930” houses). The renovation model received the Solar Decathlon Europe award in 2019. It was designed by students from Lille’s schools and universities. It is based on a healthy, inclusive and aesthetic accommodation, following the New European Bauhaus premises (environmental performance, adaptation and the aesthetics of use).

    There will be a focus on the optimisation of the renovation process with building information modelling, standardisation of solutions and mutualisation. In addition, the collaboration between academia and local actors through interdisciplinary academic projects is key. The renovation model will be tested in 2022 on houses and will then be deployed on blocks and streets on grouped sites. The investment concept will specify the legal, financial and social conditions tied to the project.


    At the technical level, the city of Lyon will seek to address all relevant issues: insulation of walls and roofs, change of windows, heating systems, hot water, lighting, ventilation and the production of renewable energy (heat network, heat pumps on groundwater, photovoltaic solar energy) of their building stock. The best available technology will be deployed to achieve the objective of approaching net-zero emissions.

    Another method to be used is to put more emphasis on performance procurement, rather than traditional (means) procurement. Raising the standards of the tender specifications is underway and is the first step of the strategy.

    Roannais Agglomération (Public entity)        

    The public entity wants to develop deep geothermal energy to produce renewable heat and electricity. Geophysical and geotechnical studies need to be conducted, including measurement campaigns and data treatment. Once these studies are done, it will be possible to define more precisely where to drill, and the drilling depth and the applicant will have a better idea of the amount of heat and electricity it will be able to produce. It will then proceed with drilling and the construction of the geothermal power station and the associated heating network.

    The investment concept focuses on the creation of smart solar PV integrated electric charging hubs to support wider adoption of electrified vehicle fleets at least cost. It will also enable high-capacity charging infrastructure by using of local generation and battery storage systems. Targeted sectors are Public Buildings, Building integrated renewables, Sustainable urban mobility and Innovative and energy infrastructure.

    Durham County Council

    The technological measures will be Solar PV, installed on lightweight car port structures over parking spaces, battery storage, with EV charging cabling and points, building or grid connections where needed. Green Infrastructure to enhance biodiversity will be added (feasibility study already conducted). At the scale proposed, and for County Durham, c. 12.8 MWp of solar PV would be installed over 8762 parking bays, with 77 MWh of battery storage and 434 EV charging points. The latter alone would double capacity in the County. A local authority does not typically work on projects of this size, and must increase the capacity to do so, the investment concept is the next step to take. Durham has many car parks, with lower levels of sustainable transport use than the regional and national average.


    The measures assessed in the net-zero roadmap for public and commercial buildings include building integrated renewables (solar PV, heat pumps) and energy efficiency measures relating to heating, cooling and lighting. Targeted sectors encompass Public Buildings, Building integrated renewables and District heating amongst others.

    London Borough of Hackney

    Technology measures proposed for the retrofit include:

    1. Improvement of the current thermal efficiency through the insulation of external walls and roofs and glazing/replacement of windows and doors to the meet the London Energy Transformation Initiative (LETI) best practice retrofit standards (Walls – 0.18, Windows – 1.2(min), Roof – 0.12 W/m2K).
    2. Installation of ‘fossil fuel’ free heat source such as air and ground source heat pumps, photovoltaic panels, and solar thermal hot water for all residents, targeting an energy use intensity of 50 kWh/m2/year, as compared to the current average energy use intensity of 71.2 kWh/m2/year seen in the buildings.
    3. Possible installation of mechanical ventilation with heat recovery (MVHR)

    On completion, all dwellings will be at least EPC B (the London Councils standards) and ideally A (+) rated.


    The properties of Hydrotreated Vegetable Oil(HVO) are extremely similar to kerosene and diesel, and it is used as a drop in fuel in existing oil boilers. However, to support this some modifications are needed including changes to the spray nozzle, increasing fuel pressure and adjusting the air intake. The estimated conversion cost for making these changes is £500 per boiler, which is relatively low when compared to the average cost of heat pump installation (£10,000). Not only would the switch to HVO have an impact on residents in the area, but also on local supply chains. This is one of the gap areas that would be analysed in the creation of an investment concept. Within Humshaugh, there is an oil buying group that operates in the area – it would be essential to understand how the pilot would affect their supply chain and if they could be involved in the distribution of HVO. Currently, there are no manufacturers of HVO in the UK - this project would explore manufacturing capabilities in Northumberland.

    Royal Borough of Windsor and Maidenhead

    The intended technology measures include: district heat networks for 2000 new homes, installation of integrated Solar PV/thermal (GSHP/ASHP package) on residential buildings using heating oil, energy efficiency (solid/cavity wall insulation, loft insulation etc.) on domestic households, renewable energy generation on domestic buildings, by solar installs (PV and/or thermal). Targeted sectors include
    Public Buildings, building integrated renewables, Residential buildings and District heating.

    In Aarhus, the focus is industrial energy efficiency. The technology development within heat pumps has in recent years reached a level where they can deliver, recover and upgrade industrial waste heat, reaching a necessary level to decarbonise thermal processes in industrial processes.

    The applications range from hot water production to upgrading waste energy to be used in other industrial processes. The challenges of HTHP (heat pumps) are the integrability into the production process industry and to match the required heat demand. The HTHP seeks to substitute liquefied petroleum gas (LPG), fuel oil and natural gas with electrically powered HTHP based on a high percentage renewable energy mix. Any derivative investments in infrastructure followed by HTHP is excluded from this project.

    The plan includes the development of a new infrastructure for bus transport, with three new bus routes. There will be a shuttle connection between the city and railway station using existing tracks. The cost includes rolling stock, signals, and tracks repairs amongst others. A new train station will also be built in Erritsø.

    Generally, the plan is focused on creating better options for multi-modal transport, including the improvement of existing transport hubs and the creation of new hubs that are flexible and attractive to use, including secure bike parking and service facilities. One of the main impacts of the project is to reduce the use of privately owned cars due to more attractive transport solutions that this project may bring.

    Frederikssund Municipality

    The investment concept include at least 5 technological themes: energy efficiency optimisation, electrification, district heating (DH), sustainable mobility, renewable energy. In industry, measures include energy efficiency in production, electrification of processes replacing natural gas and utilisation of waste heat to safeguard year-round utilisation of waste heat to reduce energy consumption for cooling and as input to district heating. In DH, measures include expanding the DH network, hence replacing the heating source for households from natural gas to efficient DH and utilising waste heat from industry to DH, hence replacing part of the natural gas driven heat production.  Sustainable mobility involves citizens in the transition by installing charging stands for electric cars, electric bicycles on subscription, and charging stands for private electric bicycles to encourage green transportation. Renewable energy includes among others solar plants, wind, heat pumpe and ATES.

    Furesø Municipality

    The project is based on previously identified energy saving potentials in the social housing sector and the main actions of the project are:
    1.update of previous screenings
    2. re-visit the housing associations to identify the status since the previous screening
    3. identification of new potentials and calculation of savings for new measures and update of savings for previously identified measures, investments and payback times
    4. preparation of a plan for the implementation of the energy saving measures and local RES production of each housing association.
    5. presentation at meetings with housing associations and departmental interest groups and residents' democracy in those associations


    The expansion of the district heating grid and utilization of surplus can be accomplished with existing technology. The planned new expansion of the Port of Hirtshals however, is planned to include a Power-to-X plant that will utilize electricity produced by local wind turbines and convert this into hydrogen fuel for large ferries.

    The investment case aims at enabling energy decarbonisation through low or zero carbon technology while increasing financing for decentralized energy production at the port.  The Municipality of Hjørring wants to make sure that sufficient grid investment will take place, since it is essential for new, intermittent energy sources like wind and solar. Danish taxation system provides a unique opportunity to install solar panels on all existing buildings on the port, as these can be considered one block while being leased to individual companies. Under Danish law, this makes it favourable to produce and sell electricity via solar panels.

    This investment concept was part of Call 5. 


    The investments will mostly target house owners and are divided into the following categories: renovations, renewable energy and heat pumps. For home renovations, the investment concept will focus on improving the climate shell of the building and isolation (wall, roof, floor and windows). This will amount to an investment of €10.000/house. As it concerns renewable energy, there will be solar panels installed on the homes - the investment of €9.000/house is foreseen.

    The last measure is the conversion of the heating system to a heat pump system. This will amount to an  Investment of €13.500/house if it concerns an individual home. In cases where an energy utility or private company builds a collective system in a village based on heat pumps, the investment will be €23.500/ house. Some house owners will implement more than one solution at the same time. In 15 municipalities, 200 house owners will choose to renovate, establish solar power and/ or change the heating system to a heat pump.

    Randers (grouping)    

    The TERMUN (Termonet in MUNicipalities) investment concept (IC) aims to accelerate the transition from fossil heating to heat pumps, but will not consist of one technical solution. TERMUN IC works across the different solutions possible for establishing solutions.  A ‘thermometer’ is a supply network that transports thermal energy from different types of energy sources. The network runs across many homes/buildings with a typical temperature of between 0 and 10 degrees. The investment needed to build a solution contains but is not limited to tendering and analysis of potential, foreseeing pipes and pumps in a horizontal or vertical system for the brine system, installing heat pumps in private houses and creating service and billing systems.


    Transition to renewable energy sources by producing enough green electricity to cover the need of electricity in the municipality (citizens, public buildings, businesses and industries). The main focus is PV technologies and solar cell parks.


    The investment concept will be developed for a project titled WeCARe IC. Its objective is to transition the car fleet to electro mobility through the financing of technical measures such as Electrical Vehicles (EVs) infrastructure. WeCARe IC specifically identifies four relevant types of EV chargers with different charging speeds and properties, necessary to ensure a full transition to electro mobility. These are the residential charger (used for charging Battery EVs at houses and flat buildings), a commercial charger (retail and hospitality locations), a so-called Fast charger (usable for charging BEV at high speed, e.g., at workplaces, campuses, commercial parking spaces) and an “ultra-fast charger” used for charging BEV at very high speed, e.g., at highway stops.

    The grouping applied consists of the following cities and municipalities: Frederikshavn, Skive, Ringkobing-Skjern, Horsens and Sonderborg og Hoje Taastrup.


    The project aims to investigate and develop options for a biogas liquefaction according to the approved SECAP action to meet the ambitious climate plan for Samsoe municipality. The project will analyse investment into the innovative micro-scale liquefaction processes using purification and biogas upgrading, bio methane liquefaction and potential use of “waste” CO2.


    The Investement Concept aims to accelerate the transition from fossil heating to heat pumps in TS whit local SP but will not consist of one technical solution for all TS. The Investement Concepts works across the different technically solutions possible for establishing a TS.
    A thermometer is a supply network that transports thermal energy from different types of energy sources. The network runs across many homes/buildings with a typical temperature of between 0 and 10 degrees. Investment needed to build a TS contains but are not limited to:

    The activities implemented will create a common investment concept for two municipalities, aiming for the organisations to be fossil-free and creating deep energy reductions. The investment concepts will cover areas pointed out as crucial to reaching local and regional targets on energy and climate.

    Measures aiming for the transition of the local municipalities (known at this point):

    • Improved energy efficiency in public building stock (aiming for 30 % energy reduction)
    • Improved energy efficiency in the public housing company (aiming for 20 % energy reduction)
    • Integration of small-scale renewables in the building stock (aiming for an installed capacity of 1500 kW)
    • Conversion of municipal vehicle fleets to renewable fuels (aiming for fossil-free vehicle fleets)

    Actions will also target the society at large and create changes on a system level, including the creation of an infrastructure for fast charging of heavy transports and accessibility to electric cars for passenger transports.

    This investment concept was part of Call 5. 


    The project is about a hydrogen production facility, including integration with the existing energy system. In addition, there will be a new bio-CCS and a new bio-char plant. For the charge-as-you-drive electric road, there will be the road integration of charging rail, charging infrastructure at end-points, transformer stations, and heavy vehicle adaptation.
    Small-scale district heating using geothermal heat and low-temperature technology is also foreseen.
    Diversity of energy renovation measures in existing building stock will be provided, including new installation of PVs (hardware and software, to be decided depending on individual building status).


    The project is about energy efficiency measures in public and residential buildings. Measures include insulation, windows, ventilation, lighting, heating etc. The methodology used is the BELOK Total Concept, which includes a switch to energy-efficient street lighting and installation of weather and motion-activated automatic regulation. The goal is to go from 30% LED to 100% LED, with an estimated yearly energy use: 3 400 MWh. They will also install solar PVs on appointed flat unshaded roofs in e.g. shopping areas. Battery storage solutions for peak shaving will also be investigated. They will develop charging infrastructure for electric vehicles with the installation of approximately 1900 charging posts for the tenants' vehicles at residential buildings owned by the local public real estate company and 600 charging posts (of which 60 fast-chargers) for public use.


    The emphasis is on the development of Uddevalla port through various sustainability measures, focusing on transport and energy. By providing fossil-free electricity to ships in the Port, the aim is to replace Marine Diesel Oil and contribute to fulfilling regulations/emission limits in the Skagerrak Sea. An underlying objective is to reduce health effects when replacing Marine Diesel Oil used close to inhabitants. The organisers will manage structural challenges to transform the infrastructure into a sustainable port system. To do this, they will buy 55 trucks and machines (electrical and hydrogen/fuel cell vehicles) and install PV 14MWp, wind power 15 MW, and batteries 20MW. They also foresee hydrogen production, storage and filling station, the first out of five hydrogen filling stations in Uddevalla.


    Energy savings in existing public and residential buildings such as recycling of ventilation air, additional insulation of attics and facades, replacement of windows, replacement of older light sources with LEDs. Exclusively renewable electricity is purchased. Most of the properties are heated with fossil free district heating, heat pumps and bio pellets, some of the properties have fossil oil boilers to phase out. Other planned investments:

    • Carbon dioxide storage - wooden constructions in new public and residential buildings 
    • Biochar as a carbon sink in rural and urban cultivation
    • Replacement of fossil to electricity operation of municipality owned maritime traffic
    • Expansion of charging infrastructure for electric cars
    • Converting streetlights from high pressure sodium to LED
    • Energy efficiency and phased out fossil oil boilers in NGO buildings
    • Solar cell parks
    • Solar cell on roofs
    • Climate optimization of sports facilities/halls (solar, heat recovery)

    The analysis will advise whether Asker should maintain and modernize the bioenergy district heating plant or replace it with other innovative and sustainable energy solutions, e.g. thermal energy from geothermal heat wells, potentially in combination with solar collectors and solar panels. Analysing opportunities, risks and costs is necessary to advance a political process for determining which investments Asker should approach to become self-sufficient with zero-emission energy for its buildings and facilities in the area.
    Perspectives for the analysis: cost and energy-effective emission-reducing alternatives.
    Environmental elements: emissions, production, transport & logistics. Financing/investment, societal perspectives/responsibilities in energy supply to other actors (public and private residents), and timeline calculations for prospect systems. Grid electricity is zero emission hydropower.

    The planned investment will include a heat pump plant and an increase in the capacity of the existing district heating network. The heat pump plant receives waste heat from a data centre and converts it into district heat. The capacity increase of the existing district heating network allows the transferring of heat from a data-centre to the city centre. The intended measures include a pre-feasibility study and development of an investment plan (engineering consultancy company, sourced via public tendering process) and a pre-feasibility study on a heat pump plant. There will be the required revisions to the existing district heating network to receive waste heat from a data centre. The technical solutions studied will represent BAT technology. In addition, there will be activities such as project coordination, reporting and communication activities, relations to project partners and stakeholders and tendering and management of purchasing services procurement.


    This project is essentially about the optimisation of the current energy infrastructure. District heating covers over 70 % of the residential heating requirements in the Cityof Tampere, which makes it a vital part of the emission reduction potential. In 2022, the biomass-fired power plant “Naistenlahti 3” is to be completed by the local energy provider, Tamperee Sähkölaitos. As a result, the local district heating production will run on biomass, natural gas and municipal waste. To achieve the city’s objective of becoming carbon neutralby 2030, this investment concept includes carbon capture in Naistenlahti 3 and a connected Power-to-X system to turn the part of the captured CO2 into synthetic fuels. Synthetic fuel can replace natural gas in peak-load boilers to help meet the heat demand in winter sustainably, and in transportation to replace fossil fuels in heavy vehicles. The Power-to-X process creates a lot of excess heat, which is captured to replace waste incineration and heat-only biomass boilers.

    Currently, there is a large battery manufacturing ground being developed near the Vaasa airport, called GigaVaasa (https://www.gigavaasa.fi).  The total acreage reserved for the two first actors is about 140 hectares, which would be good for about 100,000 battery units for electric vehicles annually. The plan is to use a quarry that is no longer in use as a combined heat storage and process water pit. The quarry is about 3 kilometers away from the actual area that is producing and further using, most of the stored heat. The quarry is to be covered in its entirety with a floating, isolated cover that allows expansion and minimises aeration. The storage volume of the quarry pit altogether would be 1.2 million cubic meters. By utilising this volume and one cycle per year, the actors of the city of Vaasa would avoid annually the production of about 53 GWh, which would further equal a reduction of 42.870 tons of CO2 equivalent.
