Central Eastern European Sustainable Energy Network

What Central Eastern European Sustainable Energy Network does

CEESEN is a non-profit umbrella network registered in Tartu, Estonia, that coordinates sustainable energy planning and climate action across 11 Central and Eastern European (CEE) countries. Founded in 2017 under the EU Horizon 2020 PANEL 2050 project and incorporated as a legal NGO in 2019, it serves as a regional knowledge base, networking hub, and policy voice for green transition actors in the CEE, including local and regional public authorities, energy agencies, NGOs, scientists, and policymakers. Its primary beneficiaries are CEE municipalities and public administrators seeking to develop Sustainable Energy and Climate Action Plans (SECAPs), reduce energy poverty, scale renewable energy communities, and meet the EU's 2050 climate neutrality targets.

CEESEN's core offering is its online platform — a communications and knowledge-sharing infrastructure created under PANEL 2050 to unify CEE energy actors — supplemented by a structured methodology portfolio. This includes the PANEL 2050 four-stage Roadmapping Model for local energy planning, an Energy Advocacy Training Programme co-developed with the University of Tartu's Johan Skytte Institute, the Forerunner Bootcamp (a week-long intensive skills programme), a Guidebook on Advocating Sustainable Energy in CEE, Regional Energy Profiles for ten countries, and Regional Energy Roadmaps and Action Plans. The organization also delivers SECAP capacity-building services for public administrators.

CEESEN operates as a community-led, project-funded network with no commercial revenue model. It does not charge membership fees; instead, it is sustained by EU grants via the Horizon 2020 programme (PANEL 2050 grant 696173; CEESEU grant 892270), the LIFE+ programme (CEESEU-DIGIT, CEESEN-BENDER, NEXUS), and an upcoming Interreg-funded project (ENTRA). Go-to-market is driven through events, conferences (Prague 2017, Tartu 2019, Budapest 2023), partner dissemination via regional energy agencies, and EU project consortia. The stated core team is small (1–10 employees), with governance distributed across a 12-member board representing partner organizations in Estonia, Latvia, Poland, Czech Republic, Slovenia, Croatia, Austria, Romania, Hungary, and Climate Alliance.

• PANEL 2050 ConsortiumcoreStrategic or Co-development PartnerCEESEN was first created as an output of the PANEL 2050 project, funded under EU Horizon 2020 (grant 696173). The project created durable and replicable sustainable energy networks at local level in 11 CEE countries. PANEL 2050 provided the foundation for CEESEN's establishment and initial operations.
• CEESEU Project ConsortiumcoreStrategic or Co-development PartnerUnder the CEESEU project (EU Horizon 2020, grant 892270), CEESEN became a legal NGO in 2019. The project aimed to build capacity of public administrators in CEE to develop SECAPs, guide municipalities in stakeholder engagement, and improve engagement between CEE public administrators and the EU.

Direct peers

• ICLEI Europe: Local Governments for Sustainability (Europe). A larger global network for sustainable cities operating very similar capacity building, climate action planning, and policy advocacy services as CEESEN, but with broader geographic reach and longer track record.
• Energy Cities: European network of local governments driving the energy transition. Closely comparable to CEESEN's mission of convening municipalities for sustainable energy planning, SECAP development, and EU-level policy advocacy; both operate as membership-based networks targeting city and regional authorities.
• REScoop.eu: European federation of renewable energy cooperatives. Directly comparable to CEESEN's energy community focus, convening cooperative members across multiple EU countries, providing training, project development support, and EU-level advocacy for citizen-led renewable energy.
• FEDARENE: European Federation of Regional Energy and Climate Agencies. Directly comparable to CEESEN as a network of regional energy agencies coordinating capacity building and policy advocacy on sustainable energy across Europe, with overlapping members including Mazowiecka Energy Agency and Tartu Regional Energy Agency.
• Climate Alliance: European network of cities and municipalities committed to climate protection. Climate Alliance is already a CEESEN board member and shares the same model of municipal climate capacity building, SECAP support, and EU-level advocacy targeting European cities and regions.
• European Energy Network (EnR): Network of European national energy agencies. Comparable to CEESEN as a coordinated network of energy agencies and intermediary bodies supporting sustainable energy policy implementation, providing knowledge exchange platforms spanning multiple countries.

Broad incumbents

• REN21 (Renewable Energy Policy Network for the 21st Century): Global multi-stakeholder network on renewable energy policy. Operates a similar convening, knowledge-sharing, and policy-advocacy model to CEESEN but at global scale and without the regional municipal capacity building focus that CEESEN delivers in CEE.
• European Council for an Energy Efficient Economy (eceee): European non-profit membership organisation promoting energy efficiency. Shares CEESEN's advocacy and knowledge-sharing model but operates across all of Europe with a broader research and policy focus, overlapping on building energy efficiency and sustainable energy training.
• Covenant of Mayors for Climate and Energy: European Commission-backed initiative uniting thousands of local and regional authorities committed to climate and energy goals. CEESEN explicitly engages with the Covenant of Mayors to support CEE municipalities' SECAPs, making it a closely related but EU-wide movement rather than a regional peer.

Emerging players

• Buildings Performance Institute Europe (BPIE): European think tank focused on building energy performance policy. Overlaps with CEESEN on building-level data digitalisation and energy efficiency advocacy for CEE municipalities, but operates as a Brussels-based policy think tank rather than a regional network.
