Territorial Cooperation—A Factor Stimulating Baltic Sea Region Energy Transition

Abstract

Energy transition is a multi-dimensional process of developing sustainable economies by seeking renewable energy sources, saving energy, and improving energy efficiency. This process follows the rules of sustainable development. The article presents an analysis of energy transition in the Baltic Sea Region (BSR) enjoying long-term and intensive territorial cooperation. The region embraces 11 countries diversified in terms of their economic development level and the use of renewable energy sources. The article strives to answer the question of whether territorial cooperation contributes to BSR energy transition, and if so, in what way. Another goal is to identify the transition drivers that arise from the Baltic Sea Region’s unique characteristics. The authors applied the system analysis methodology. The performed literature studies allowed the researchers to identify the attributes of energy transition. Empirical research relied on secondary sources, including the European Union (EU) statistics, The International Renewable Energy Agency (IRENA), the EU Strategy for the Baltic Sea Region (EUSBSR), and related documents. The key role in the conducted research can be attributed to the EU projects database (keep.eu), which enabled identifying the 2016–2020 programmes and projects. The research identified 14 BSR territorial cooperation programmes and 1471 projects conducted under the programmes, including 137 energy transition-related projects. The project results were presented in quantitative and qualitative terms.

1. Introduction

The subject of energy transition is widely reflected in scientific literature [1,2]. Energy transition leads to replacing economies based on fossils to economies relying on renewable sources [3]. Researchers argue that transition is not just a technological change, but it is a process [4] that requires a combination of economic, political, institutional, and socio-cultural changes [5,6,7].

The transition landscape is more complex [8]. Transitions vary from country to country, and they sometimes vary even within the same country due to distinct challenges imposed by topography, the historical evolution of national energy markets, and cultural variables [9]. The methods of generating and using particular forms of renewable energy vary [10]. The International Renewable Energy Agency (IRENA) identifies six basic forms of renewable energy [11] and analyses their development worldwide (Figure 1).

Renewable energy sources have two important functions in sustainable transitions: they create new nature-provided capital, and at the same time, they significantly reduce greenhouse emissions and contribute to restoring the planet’s assimilation capacity [12]. Renewable energy sources provide electric energy and heat. A technological challenge remains regarding energy storage and proliferation [13]. The proliferation of renewable energy generation sources and micro-grid distribution systems allows operators to supply aggregated loads by electricity purchases from a transmission grid or from a locally generated renewable energy source (e.g., solar, photovoltaic, or wind). Renewable energy resources and technologies are the key components of sustainable development for three main reasons [14]:

1. They have a lower environmental impact than other energy sources. The multiplicity of renewable energy resources allows a diverse range of application.

2. They are not depletable. Renewable energy sources, when employed correctly in appropriate applications, can provide a steady and sustainable supply of energy.

3. They support system decentralisation and local solutions that are relatively independent of the national network, so increasing system flexibility and offering economic benefits to isolated communities. Furthermore, the small scale of the equipment frequently decreases the time necessary from initial design to operation, allowing for greater versatility in responding to unforeseen growth and/or changes in energy demand.

Energy transition is part of a wider process called sustainable transition [15,16]. According to McIntosh [17], there are many transitions taking place simultaneously: a move from high-emission economy to low-emission economy, from social inequality to egalitarianism, from everyday practice of breaching human rights to socially fair societies. Ropke draws attention to the fact that there are many areas requiring change, including such systems as production, consumption, energy distribution, transport, and agriculture [18].

For years, it was assumed that economic stability may be based on the economic growth concept. However, this approach favoured the growing consumption of natural resources and energy.

At the same time, the production of waste and the greenhouse effects kept growing. Ryszawska emphasises that such economies generate a vicious circle of interdependencies, as production growth causes consumption growth, and the latter in effect leads to the growing use of natural resources and higher emissions [19]. The ambitious goal of sustainable transition requires a move from brown economy to green economy (Figure 2). The energy transition must be regarded as part of a wider process of sustainable transition. It is essential to view changes in renewable energy use in a broader context and to integrate them into other efforts for sustainable development.

Loorbach underlines that energy transition requires new alternative approaches [20] appraising visions and concepts as well as stimulating participatory–deliberative processes to move the collective and political nature of transitions forward [21].

Significant factors favouring energy transition include the following [14]:

1. The establishment of renewable energy markets;

2. Experience with renewable technologies;

3. The removal of barriers and constraints to the diffusion of renewable energy;

4. The establishment of a legal, administrative, and financing infrastructure to facilitate planning and implementing renewable energy projects;

5. The promotion of renewable energy technologies by initiating surveys and studies to establish their potential at the local and regional levels.

A system interpretation of the transition process is presented by Geels [22]. He describes how transitions in socio-technical systems can be understood as reconfigurations of dynamically stable socio-technical regimes within these systems. These regimes represent the prevailing configuration of existing technologies, scientific fields, incumbent industrial actors, and institutional structures. Regime reconfigurations emerge through the interaction of three elements (Figure 3):

• Niches;
• Socio-technical regimes (the locus of established practices and associated rules that stabilise existing systems);
• Socio-technical landscape.

Niches usually refer to research and development laboratories where entrepreneurs, inventors, and other actors strive for radical innovations. Usually, these activities are stimulated by subsidised projects. Socio-technical regimes mean a platform of established practices and associated rules that stabilise existing systems. The socio-technical landscape shapes transitions through physical and geographical factors that cannot be affected by regime actors or niche factors.

Numerous external factors may have an impact on niche development, including international cooperation stimulating energy transition [23,24,25,26]. Territorial cooperation [27] is a special case of international cooperation involving sub-state bodies (e.g., local administration, NGOs, research institutes). Such collaboration may stimulate sustainability transition.

In the European Union, territorial collaboration finds financial support in the Cohesion Fund and neighbourhood policies supporting international projects [28] contributing to the energy transition of towns, cities, and regions [29]. The European Commission underlines that regional and local authorities often set more ambitious renewable targets that exceed national targets [30]. Concurrently, the Commission successively improves the instruments of territorial cooperation [31] to support investments for energy efficiency in sustainable renewable energy and in intelligent energy systems. A need arises to evaluate both the present condition and the development trends to show the directions of territorial cooperation development.

2. Goals and Methodology

The goal of the article was to answer the question of whether territorial cooperation contributes to BSR energy transition, and if so, in what way. The goal has been achieved by applying the system analysis methodology. System in the broadest sense means a set of interacting units with relationships among them [32,33]. The concept of the system has been used in social sciences for many years, as it enables a holistic view of the analysed phenomenon or process [34]. System analysis became a problem-solving process that breaks a system down into its component parts in order to study how well those component parts work and interact to achieve its goals [35]. This method seems to be one of the crucial inventions without which effective management in any field of human life, including socio-economic management, would be inconceivable [36]. System analysis has its limitations because it is the researcher who subjectively identifies elements of the system and interprets the relationships that occur between them.

The research model designed for the purpose of this article assumed three stages of analysis:

1. Analysis of the territorial cooperation landscape in scope of BSR energy transition;

2. Analysis of the territorial cooperation organisation in scope of BSR energy transition;

3. Analysis of the territorial cooperation effects in the scope of BSR energy transition.

Three sub-systems were the subject of analysis: The Baltic Sea Region as a transnational area, territorial collaboration as a form of international cooperation, and energy transition as an element of sustainable transition (Figure 4).

Literature studies were conducted and data acquired to identify the attributes of energy transition. Empirical research relied on secondary sources, including the European Union (EU) regulations, The International Renewable Energy Agency (IRENA) statistics, the EU Strategy for the Baltic Sea Region, and related documents. The key role in the conducted research can be attributed to the EU projects database (keep.eu), which helped to identify the completed 2016–2020 programmes and projects supporting the BSR energy transition. Project analysis shows the quantitative and qualitative results of cooperation.

3. The BSR Territorial Cooperation Landscape

The Baltic Sea Region is defined and delimited in various ways. In the narrow meaning, it covers eight Baltic states, i.e., Denmark, Sweden, Finland, Russia (northern regions), Estonia, Latvia, Poland, and Germany (northern regions). In the wider meaning, the region embraces also countries of the Baltic Sea catchment area: that is, Norway and Belarus [37]. International cooperation lasted many years in the Baltic Sea Region [38,39] underwent dynamic acceleration with Poland and the Baltic States joining the European Union in 2004. Soon, the Baltic Sea region stood apart from other transnational regions, including EU macroregions, because of the high level of cooperation between local, regional, and national authorities. The BSR states, cooperating within the Council of the Baltic Sea States, were the initiators of the Baltic integration at the end of the twentieth century. Cities and regions have increased their activities throughout time, and they have also developed networking organisations. In such conditions, multi-level collaboration in the Baltic Sea region was required to be coordinated. This was made feasible in large part by an EU initiative in which the Baltic Sea Region’s countries agreed to establish and implement a macro-regional strategy, namely the EU Strategy for the Baltic Sea Region [40]. The primary objective of the strategy was to save the Baltic Sea, to connect and to augment the prosperity of the region. Renewable energy development improves all these areas and is the key factor in implementing EU energy policy priorities [41]. The first Action Plan of EUSBSR emphasised renewable energy problems [42].

One of the strategy tasks was to reduce disparities in using renewable energy sources in BSR. The study of BSR usage of renewable energy in the years 2010–2019 (Figure 5) showed that the region presented positive results compared to the entire EU [43]. Nevertheless, the region included states that managed well the use of renewable energy (Norway, Sweden) and others (Germany, Poland) that considerably lowered the average.

The relations between energy efficiency and renewable energy use are also worthy of attention (Figure 6). Countries enjoying the greatest energy efficiency (Norway, Sweden) demonstrate the best renewable energy use indicators. Germany and Poland found themselves on the other end. In 2014, the mean energy efficiency indicator in BSR read 71.97% with the mean energy efficiency use indicator of 33.55%. German indicators read 38.3% and 14.38%, respectively, and Poland showed 30.1% and 11.6%, respectively. Scientists studying energy issues agree that the development of renewable energy requires not only resigning from non-renewable energy but also “creating sustainable energy development and supporting cooperation” [44].

The use of particular types of energy in BSR states is diversified (

). Renewable power generation capacity is measured as the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity [45].

Comparing the structure of renewable energy capacity in BSR countries in the years 2011 and 2020 (Figure 7), we can note the dominant position of hydropower energy. However, the use of wind energy and solar energy showed a percentage growth.

The summary of the renewable energy capacity in EU member states of BSR in 2011 and 2020 is interesting (Figure 8). Analysing the above data, we note a spectacular 132% increase in wind energy capacity. The share of wind energy in the structure of renewable energy capacity increased from 28% to 43%, and wind energy became the leading source of renewable energy.

In the political and scientific discussions on how the Baltic Sea Region contributes to the sustainable transition of the energy sector, the development of offshore wind potential is considered a crucial element [47]. The awareness of the existing vast potential as well as economic, energy, and environmental benefits of investment has led to more intense recent cooperation of stakeholders on these issues.

The development of energy collaboration requires grid ‘connections’ among countries around the Baltic (Figure 9). Up to date, three different synchronic grids operate in the BSR:

• Nordic (Finland, Sweden, Norway);
• Baltic (Lithuania, Latvia, Estonia);
• Continental (Denmark, Germany, Poland).

The BSR faces the challenge of developing a concept for integrating these grids, which would involve, inter alia, the construction of cross-border transmission capacity infrastructure. The connections between Poland and Sweden completed in the year 2000 and those between Estonia and Finland (2007) started a new era in mutual connections. Successive underwater cable connections are at the designing phase and investment preparations.

4. Organisation of Territorial Cooperation in BSR Energy Transition in the Period 2014–2020

The development of territorial cooperation within BSR was financially supported by the EU cohesion policy instrument called the European Territorial Cooperation (ETC). The cohesion policy followed the provisions of the Treaty on the Functioning of the European Union, which committed EU bodies to undertake measures to enhance economic, social, and territorial cohesion and reduce disparities between the levels of development of the various EU regions [48]. The European Structural and Investment Funds were established to finance these measures. One of the funds—the European Regional Development Fund—ensured financial means for ETC. Three types of territorial cooperation were identified [49]:

1. Cross-border cooperation between regions divided by the state border;

2. Transnational cooperation covering a larger area on the territory of at least two countries;

3. Interregional cooperation involving regions in different parts of the world.

In the years 2014–2020, 14 ETC programs functioned in the BSR: 1 international, 1 transnational, and 12 cross-border programmes (Figure 10).

Each of the ETC programmes provided a different option for energy transition undertakings. This variation stemmed from the programmes’ architecture and relations between determinants of cooperation such as specific objectives, investment priorities, and intervention priorities (Figure 11).

Thematic objectives for EU programmes were defined in line with Agenda 2020 priorities [51] supporting smart, sustainable, and inclusive growth. The European Commission set 11 Thematic Objectives (TO) in ETC programmes for the period 2014–2020 [52] based on three priorities of Agenda 2020 (Figure 12).

The 11 TOs comprised 38 investment priorities. Issues directly related to energy were included in three (IP) under Low-carbon economy TO 4 and one IP part of TO 7 Sustainable transport.

• (IP 4a) Promoting the production and distribution of energy derived from renewable sources;
• (IP 4b) Promoting energy efficiency and renewable energy use in enterprises;
• (IP 4c) Supporting energy efficiency, smart energy management, and renewable energy use in public infrastructure, including in public buildings and in the housing sector;
• (IP 7 c) Improving energy efficiency and security of supply through the development of smart energy distribution, storage, and transmission systems and through the integration of distributed generation from renewable sources.

The European Commission recognised the significance of renewable energy in territorial cooperation so that instructions appeared in ETC programmes on how to proceed with renewable energy projects in the remaining TOs. This step facilitated studies on renewable energy (under TO 1), adaptation of ecosystems applying renewable energy (under TO 6) and supporting the renewable energy sector (under TO 3). For measures funded by the ERDF, nine groups of Interventions (Figure 13) were identified comprising in total 123 Interventions.

Intervention group number 2 identified the strand Energy Infrastructure (Figure 14) comprising 16 Interventions including four related to renewable energy: wind energy, solar energy, biomass energy, and others. The last category embraced hydroelectric, geothermal, and marine energy and renewable energy integration including storage, power to gas, and renewable hydrogen infrastructure.

.

Investment Priorities related to energy appeared only in one ETC programme; nevertheless, energy-related Interventions appear in three programmes, whereas energy Specific Objectives appear in four programmes. The analysis of particular programmes indicates that in their majority (except for two programmes), they contain provisions connected with energy. Some programmes (inter alia, transnational Baltic Sea programmes) treat energy issues as a priority (

Table 3. Energy issues in ETC programmes for BSR in the period 2014–2020.

No.	Programme	Energy Issues Described in the Programme and Energy Specific Objectives
1.	Europe	The question of renewable energy and energy saving is clearly emphasised. The programme includes proposals to organise study visits, the working out of strategies for the development and use of renewable energies, creation of a web-based database of successful initiatives, and demonstrations of sustainable energy.
2.	Baltic Sea	Clearly underlined is the need for transnational cooperation on energy issues. The programme is looking for proposals enhancing the capacity of energy sector actors to jointly develop or improve the energy storage capacity and distribution patterns (development and reorganisation of smart grids, integration of storage) and to coordinate energy networks (electricity, gas, heating). The programme strives to support proposals that will enhance the capacity of stakeholders and actors to improve energy efficiency when developing new quarters or retrofitting building blocks, primarily in cities.
3.	Central Baltic	The question of energy is not touched except for actions towards saving energy and the use of renewable energy for the development of small harbours.
4.	South Baltic	The proposal for energy cooperation including renewable energy is clearly emphasised. A postulate was put forward demonstrating and implementing small-scale green technology investments (pilot projects) in the production of energy from renewable sources (e.g., wave, wind and solar energy, biomass, geothermal energy, etc.) and renewable energy storage, developing and testing of innovative cross-border solutions aimed at improving and coordinating sustainable energy networks (e.g., development and reorganisation of smart grids, virtual power plants, heating supply, integration of storage, maritime transmission grids).
5.	Nord	The programme refers to energy issues. It postulates the development of renewable energy sources, ecological sustainable industry, and optimal use of energy.
6.	Sweden–Denmark–Norway(Öresund–Kattegat–Skagerrak	Energy issues and renewable energy are deemed to be of great importance. A suggestion was put forward to develop business initiatives on alternative energy sources by strengthening and by the use of a common Scandinavian energy grid market and the development of energy technologies, services, and products.
7.	Sweden–Norway	The programme points to cross-border transport as a source of pollution threats. It postulates the use of renewable energy sources in transport. Furthermore, an exchange of experience in bioenergy is strongly suggested.
8.	Lithuania–Poland	No reference is made to energy.
9.	Latvia–Lithuania	No reference is made to energy except for the postulate to raise social awareness of the need to save energy.
10.	Estonia–Latvia	No reference is made to energy except for a postulate to undertake measures to raise awareness of the need to save energy.
11.	Denmark–Germany	The programme postulated the synergy action of research and commercial organisations on renewable energy and energy efficiency. It indicates the need to build energy clusters. It also postulates e-mobility and wind energy symbiosis.
12.	Germany Brandenburg)–Poland	No reference is made to energy.
13.	Germany (Meklemburg–Western Pomerania, Brandenburg)–Poland	The programme includes postulates for renewable energy grid cooperation.

). Within the framework of these programmes, 1471 projects were carried out in total. The joint number of projects, including energy Investment Priorities (IP 4a and IP 4c), numbered 21. According to the keep.eu database, 40 projects were completed under the Theme Renewable energy, and 58 projects were completed under the Theme Energy efficiency. The term ‘energy’ in the description was found in 186 projects. Projects selected according to the criteria given above were studied in detail, which allowed for the final identification of 137 energy projects. The number of energy projects in particular programmes ranged from 1 to 34, whereas the percentage share of energy projects oscillated between 0.76% and 24.14%.

5.1. Projects of the Interregional Programme

The interregional cooperation programme INTRREG Europe 2014–2020 is a programme covering Europe. BSR is only part of Europe. Entities from the entire area of Europe were partners in 250 projects. Only those projects that included at least two BSR entities were further analysed. From amongst these projects, 34 energy projects were chosen.

5.2. Projects of Transnational Programme

The transnational cooperation programme Baltic Sea completed 181 projects. Thirty-six projects contained the term energy. The keep.eu database allocated seven projects to the Theme Renewable Energy and 13 projects to Energy Efficiency. Verification of the project descriptions revealed 23 energy projects.

5.3. Projects of the Cross-Border Programmes

Within the framework of twelve cross-border cooperation projects, 1040 were completed, including 80 energy projects. The greatest number of projects (21) was completed in the programme Sweden–Denmark–Norway (Öresund–Kattegat–Skagerrak). This was the only programme with energy Investment Priorities. The fewest number of projects (one each) was completed in the cross-border areas of Lithuania and Poland, Lithuania and Latvia, and Poland and the German Land Saxony. The keep.eu database assigned 23 projects to the theme Renewable Energy, whereas 32 projects were assigned to Energy Efficiency.

5.4. The Subject Range of Territorial Cooperation

The quantitative study of 137 projects identified nine subject categories (

) including five renewable energy categories: wind, biological, thermal, solar, and water energy. Among the 37 energy projects in the range of specified sources of renewable energy, the greatest number (15) concerned biological energy and the fewest (2) concerned thermal energy. A very popular cooperation category was energy efficiency (53 projects) and energy transition (42 projects).

6. Territorial Cooperation Effects in BSR Energy Transition—Qualitative Analysis

6.1. Use of Wind Energy

The development of wind energy in SUERMB was recognised as a priority of energy transition in the region and is reflected in the concluded projects. The project Integrated Baltic offshore wind electricity grid development, financed by INTERREG Baltic Sea, created the Baltic Offshore Grid Forum cooperation platform gathering key wind energy stakeholders. These included transmission system operators, offshore wind energy industry, policymakers, national authorities, and academics. Studies were conducted that produced a diagnosis of the present situation and indicated wind energy cooperation scenarios in the BSR. Four scenarios were adopted (Figure 15):

• Wind farm built in domestic territory (baseline option);
• No cross-border restrictions;
• Limited interconnection capacity, identical generation fleets;
• Limited interconnection capacity, different generation fleets.

Additionally, a vision of developing wind energy was elaborated to the year 2050 (Figure 16). Current proposals for offshore wind farms and interconnections suggest that the key component of the 2050 vision could be a combination of the southwest and southeast meshed grid systems. Wind farms close to the shore would be expected to be connected radially, whereas wind farms further from the shore would be expected to be connected via the integrated grid. As a secondary emphasis, Estonia, Finland, and Sweden would be considered in the northern half of the Baltic Sea. The agenda also projects a third priority: connecting the northern and southern systems via a setup off the Baltic Sea coastlines. To achieve the set goals, a list of recommendations was worked out regarding the policies, regulations, and maritime spatial planning. The Baltic Lines project [68] allowed marine spatial planners in Baltic Sea countries to coordinate their national plans for developing energy corridors with shipping routes, hence improving connectivity throughout the Baltic Sea. Cooperation along the Danish and German border resulted in innovative projects for household wind farms.

6.2. Use of Water Energy

Water energy issues appear in three cross-border projects. A project on the border of Lithuania and Latvia resulted in identifying inadequate water flow in lower water energy plants and in assessing the ecoflow [69]. Recommendations were put forward to review the national water law, which affected the strategic planning of water use and the issue of permits. In Scandinavia, cross-border projects promoted water plants as a cultural heritage attraction [70].

6.3. Use of Geothermal Energy

Two projects were dedicated to geothermal energy. Within the transnational project Baltic Sea Underground Innovation Network, a network of underground laboratories was established for the transfer of scientific technologies and exchange of good practices (Figure 17).

Abandoned mines were adapted to conduct studies on geothermal energy [71]. A method for measuring the thermal neutron stream [72] was developed. The European Underground Laboratories Association (EUL) was established to promote research, technology development, innovation, education, and events organised in underground laboratories [73]. Furthermore, methods for heating buildings with geothermal energy were implemented.

6.4. Use of Bioenergy

BSR benefited from 16 bioenergy projects, including an ambitious project of establishing an international consortium for improving the effective and sustainable use of biomass to produce energy [74]. The developed GIS platform presented the potential of forest biomass in specified BSR geographical areas [75]. Work started on developing an atlas of forest energy (Figure 18).

A plan for the development of small bioenergy power stations was developed for rural areas of the Baltic Sea Region. Actions were undertaken to develop regional bioenergy policies [77]. Territorial cooperation for the development of bioenergy covered, inter alia, such issues as the use of sewage, energy plants, and waste. The Biogas 2020 project [78] initiated measures to make Scandinavia the leader of sustainable production and use of biogas.

6.5. Use of Solar Energy

The cross-border programme Central Baltic financed four projects that contributed to the use of solar energy in coastal harbours. The ports of Finland started featuring innovative solar panels [79]. The project Energetic Small Ports in the Central Baltic Region [80] played an important role in the development of a cooperation network embracing ports implementing investments and other ports interested in cooperation (Figure 19).

6.6. Using Renewable Energy in the Development of Transport

Six projects conducted within the programme of interregional cooperation INTERREG Europe facilitated the exchange of good practices in the development of local transport development using renewable energy (RE). In the cross-border area of Sweden and Norway [81] as well as Sweden and Denmark, the local transport projects were based on hydrogen fuel. The project goal was to reject fossil fuel in the development of local public transport [82].

6.7. Energy Storage

Five projects were completed within the cross-border programmes devoted to improving methods of energy storage. The projects involved, inter alia, the circular industrial symbiosis model, which assumed the storage of energy generated by waste [83] and rules of storing energy in buildings [84]. The developed Vehicle-to-Grid (V2G) concept assumed the use of electric vehicles as sources for energy storage. The concept was tested in the northern areas of the BSR [85].

6.8. Energy Effectiveness

Work on improving energy effectiveness in the BSR was conducted in 53 projects financed by 10 ETC programmes. The project Effective Financing Tools for implementing Energy-Efficient Buildings gained the status of the EUSBSR flag project. Measures were undertaken at the local level to improve the effectiveness of buildings by promoting innovations [86], the development of energy monitoring [87], and the support of public orders supporting energy saving [88]. Territorial cooperation supported a number of various enterprises devoted to energy saving in transport, heating systems, lighting systems, data centres, sport facilities, agricultural infrastructure, and sewage plants. The established forum of science and implementation institutions of the Baltic Science Network supported innovative solutions for energy effectiveness [89].

6.9. Energy Transition

Territorial cooperation in energy transition embraced 48 projects, which had a significant educational dimension. The key partners gathered mainly business, self-governmental authorities, and local societies. A number of local energy transitions strategies were developed. The developed recommendations for improving spatial planning for renewable energies in the Baltic Sea Region [90] contributed significantly to energy transition. The value chain for transnational renewable energy projects (Figure 20) presented directions of further cooperation.

It has been agreed to extend spatial planning for renewable energies to include spatially relevant aspects of large-scale production and logistics of renewable energy raw materials. Consecutive stages were projected, indicating the locations of plants, development of plant concepts and energy storage, and long-distance energy transport and logistics. The last element is the development of distribution infrastructure, storage, and consumption. Four levels of cooperation were specified with assigned key projects (Figure 21).

Territorial cooperation resulted in developing a number of local energy transition programmes. Renewable energy became part of numerous strategies for the intelligent specialisation of some Baltic regions [91]. Instruments were developed encouraging the use of RE in production in municipal and rural areas. BSR initiated cross-border clusters of clean energy [92] and cooperative partnerships for renewable energy supporting community energy project development [93].

7. Conclusions

The conducted study proves that territorial cooperation contributes to energy transition in the Baltic Sea Region primarily thanks to the financial support of the EU cohesion Fund in conducting joint projects. The spatial dimension and cooperation effects depend on the territorial cooperation priorities and programme goals. The programmes supported energy transition in various ways. Some cross-border projects bypassed energy issues completely, while others marked them as a priority. The projects completed within the framework of the programmes covered all types of renewable energy accounted for in the IRENA statistics. The only exception in the BSR was ocean energy. The majority of projects focused on the development of bioenergy. Nevertheless, it worth noting that in the years 2011 to 2020, the interest in this type of renewable energy showed a falling trend in EU BSR countries. However, the period featured a spectacular rise of interest in wind energy. Cross-border cooperation followed this trend and specified further priorities and scenarios for the development of wind farms. The project Baltic InteGrid: towards a meshed offshore grid in the Baltic Sea became of special importance for energy transition. It showed a common energy grid for the entire region.

The specificity of the territorial cooperation projects was their minor budget, which created limited options for investments. Territorial cooperation contributed to the development of a collaboration network and in effect to the promotion of good practices in energy transition. BSR involvement in renewable energy, in the saving of energy, and in improving energy efficiency brings the region closer to the vision of a leader in the sustainable development in Europe.

The system analysis method was employed in our study. The limitations of this method originate from the fact that the researchers were the ones who identified the system’s components and interpreted the relationships between them. Only territorial cooperation in the narrow sense as a goal of the European Union’s cohesion policy was investigated. The qualitative analysis of the projects posed a significant problem due to the usage of a database in which the projects were presented in a variety of ways. We were unable to complete the whole project documentation due to time and financial constraints. In our opinion, research concerning the long-term effects of completed projects is necessary. Furthermore, future research could focus on the topic of territorial cooperation coordination within the EUSBSR. This is significant because one of the priority topics in the strategy’s governance system is energy. However, we believe we have developed an essential diagnosis that policymakers might employ in their subsequent follow-up.
