Boosting urban solar revolution for Central Europe

Programme 2021 - 2027 Interreg VI-B Central Europe

Date of latest update: 2025-03-13

Description

Description (EN):

Solar4CE-Cities aims to response the recent energy crisis pressures on CE region having a heavy dependence on natural gas import. Volatile energy prices and growing energy bills evenly affect all actors, such as public bodies, municipalities, institutions, citizens and businesses. Combatting this can be best achieved by a swift solar power penetration in cities. Widescale deployment of PV panels on rooftops, also set as a key intention by EU Solar Strategy, are impeded by administrative, technological, financial, and knowledge barriers faced by citizens and other end-users in lack of supportive policy frameworks. To tackle this joint transnational challenge, 3 local public authority and infrastructure service provider partners from Budapest, Udine and Maribor, supported by 2 higher education and research organisations partners from Austria and Germany, will commonly develop replicable solutions, focusing on the novel concept of prosumption. To bring a real change, transnational cooperation is central because cities joining forces can elaborating efficient transferable tools and strategies, as well as stimulate national governances to take effective steps to clear policy obstacles, while also providing a bottom-up support. To achieve this, Solar4CE-Cities will jointly assess the feasibility of complementary collective and cross-sectoral prosumer schemes, establish innovative business models and pilot communities adopting them, co-developing a transnational strategy promoting urban prosumerism and translate it to tailored local actions via an overall active involvement of stakeholders including citizens. Solar4CE-Cities Mission alliance formed by PPs and APs will bring forward the results also after the project lifetime. In three years of cooperation efficient policy tools set up are expected to lead to wide-spreading of urban solar power which will contribute to both strengthen energy security of CE cities and regions, and reach climate neutrality targets.

Expected Achievements (EN):

To jointly elaborate transnationally applicable policy guidance for both city and national level governances on how to overcome common challenges of solar PV penetration in CE cities through co-creating a complex enabling environment by cross-sectoral local collaboration schemes, and a durable transnational cooperation framework launched by Solar4CE-Cities partners. To jointly develop replicable business models based on assessing and revealing the administrative and technological feasibility and economic viability of collective and cross-sectoral urban solar prosumer schemes that utilize innovative technologies, and establishing local pilot prosumption communities. To translate the envisioned measures for boosting solar revolution in CE cities of the Solar4CE-Cities Transnational Strategy into local actions, through co-developing a comprehensive enabling framework and local project roadmaps of collective prosumer schemes with an overarching participatory approach.

Contribution to wider strategies and policies:

EuropeanGreenDeal The project supports reaching the climate neutrality goal of the European Green Deal for 2050, and the 2030 EU emission reduction target through offering CE cities a set of enabling tools to accelerate solar power deployment and thus increasing the share of renewables. The long-term objective of the project is to develop self-sufficient and resilient solar power supported urban electricity systems which contributes to the Green Deal’s key principle of ensuring a secure energy supply.
TerritorialAgenda2030 By facilitating the increase of solar power share in urban energy mix and offering solutions for future power distribution challenges, the project contributes to achieve Sustainable Development Goals of the Territorial Agenda 2030. By fostering the enhanced use of PV technology and solar powered e-mobility, it also contributes to reach a healthy environment that is a key to build a Green Europe which is an overarching objective of the Agenda.
EUStrategyDanubeRegion By addressing solar energy to increase energy independency and launching a multipurpose cross-border RES utilization project, Sustainable Energy (PA2) as one of the priority areas of EUSDR is supported. Energy efficiency goals and use of renewable energy contribute to find alternative solutions for fuel-based local transport systems which are targets of PA2. Exchange of innovative solutions between PPs improves regional cooperation and creates synergies which is also at the heart of EUSDR.
EUStrategyAdriaticIonianRegion By analysing the policy practices, costs and benefits as well as modelling the expected impacts of future urban electricity demand and additional solar power generation on the grid capacity, the project contributes to the implementation of the EUSAIR Action Plan. The Strategy fosters the development of energy networks and by assessing the possibilities of a well-functioning electricity market within the project it adds to the targets of EUSAIR.
EUStrategyAlpineRegion Cross-sectoral stakeholder groups with wide-scale expertise to be engaged in the project will have a high potential of contributing to the Alpine Energy Efficiency Cluster through co-developing novel technical solutions also able to improve energy efficiency performance. The GIS-based solar potential and demand mapping tool to be developed and tested in Solar4CE-Cities might be replicated by cities in the Alpine Region with integrating it into the energy efficiency and decentralised RES monitoring systems as set forth in the Action Plan.
Other As part of the REPowerEU plan, EU Solar Strategy aims to bring online over 320 GW of solar photovoltaic by 2025 and almost 600 GW by 2030, via the European Solar Rooftops Initiative which promotes quick and massive PV deployment by making permitting procedures shorter and simpler through adoption of an EC legislative proposal, recommendation and guidance. It sets forth MSs establishing robust support frameworks for rooftop PV systems, including in combination with energy storage and heat-pumps, and strives for energy poor and vulnerable consumers having access to solar energy e.g. through social housing installations. Solar4CE-Cities is fully in line with and supports these ambitions by furthering CE cities to co-design and implement enabling schemes for rolling-out collective prosumer schemes operating joint PV plants.
Other CEP sets an ambitious, binding target of 32% for renewable sources in the EU’s energy mix by 2030. Within the package the recast of the Electricity Directive and the revised Renewable Energy Directive (RED II) defined the term of renewable energy community (REC) providing legal background to develop such communities and increase the role of citizens in EU’s energy transition. Transposition to national laws has happened, though not yet the implementing regulations ensuring the support schemes required by REDII have been enacted in the PP countries, which hampers to launch and operate RECs on the ground. Conveying Solar4CE-Cities pilot experiences in developing REC-like collective prosumer business models, and the linked policy recommendations to national decision-makers enable to facilitate the compliance of national requirements set forth by CEP.
Other Energy Union Strategy (EUS) aims at building an energy union that gives EU consumers (households and businesses) secure, sustainable, competitive and affordable energy. It strengthens energy communities ensuring effective implementation of the EU's energy, environment and competition acquis, energy market reforms and incentivising investments in the energy sector. The analysis in Solar4CE-Cities on supporting frameworks for prosumerism and energy community schemes based on the energy union reports contributes to the aims of the EUS by fostering citizens’ participation in the energy market.
Other The ultimate objective of Solar4CE-Cities is to support the transformation towards climate neutrality of the participating cities by 2030 which is also the aim of the 100 Climate-neutral Cities Mission, which City of Budapest (LP) participates in. By tackling not only political actors, but also users, producers, consumers, owners within cities to raise awareness about the benefits of SP systems it adds to engage all relevant actors giving answer to some of the main challenges the cities face when trying to put transformations in motion.
