The third instalment of the partnership will contribute to the expected outcomes specified in topic HORIZON-CL5-2021-D3-01-04: Clean Energy Transition, for continuation and development of new activities. The partnership is expected to contribute to all of the following expected outcomes: • Increased directionality of clean energy transition research and innovation in EU and Associated Countries in line with the SET Plan thanks to a shared pan-European vision on the goal and direction of required system transformation processes, adapted to regional needs and availability of renewable energy resources; • Evidence based energy and climate policy formulation; • A wider systemic transition and energy supply required for a climate neutral economy in all sectors of society; enabling the transition of the built environment, transport, industry and other sectors to clean, low carbon energy; • An innovation ecosystem for Europe's transition to clean energy and contribution to a resource and energy efficient system, both from an ecological and economic standpoint; • A building block to a zero-emission energy system for the decarbonisation of transport, buildings, industry, agriculture in the specific European environment; • Increased engagement of consumers and prosumers as well as fair and appropriate demand-response mechanisms integrated in the energy system; • An energy system that meets the needs of different parts of society, in different geographical locations (urban and rural) and different groups. Scope:The Clean Energy Transition co-funded Partnership (CET Partnership) is a transnational initiative on joint R&I programming to boost and accelerate the energy transition, building upon regional and national R&I funding programmes. It aims at empowering the energy transition and contributing to the EU goal of becoming the first climate-neutral continent by 2050, by pooling national and regional R&I funding for a broad variety of technologies and system solutions required to achieve the transition. It will foster innovation ecosystems from the very local and regional level, up to the transnational European level, thus overcoming a fragmented European landscape. The CET Partnership enables national and regional R&I programme owners and managers from Member States and Associated Countries to align their priorities and implement annual joint calls from 2022 to 2027. The Partnership also organises joint accompanying activities to enable a dynamic learning process, extracts strategic knowledge and accelerates the upscaling, replication, and market diffusion of innovative solutions to maximise impact and foster the uptake of cost-effective clean energy technologies. The common vision of the CET Partnership is already expressed in its Strategic Research and Innovation Agenda (SRIA) that has been co-created with the involved countries, the EU SET Plan Implementation Working Groups and ETIPs, all energy relevant ERA-Nets as well as the EERA joint programmes (over 500 editors, co-authors, commenters, and discussants). The SRIA articulates the common goal of (1) building a transnational transformative Joint Programming Platform, (2) developing and demonstrating technology and solutions for the transition of energy systems, and finally (3) building innovation ecosystems that support capacity building at all levels. The objective of this action is to continue to provide support to the European Clean Energy Transition Co-fund Partnership identified in the Horizon Europe Strategic Plan 2021-2024 and first implemented under topic HORIZON-CL5-2021-D3-01-04, and in particular to fund additional activities (which may also be undertaken by additional partners) in view of its intended scope and duration, and in accordance with Article 24(2) of the Horizon Europe Regulation. The new geopolitical and energy market realities require to drastically accelerate the clean energy transition and increase energy independence from unreliable suppliers and volatile fossil fuels. In support to the objectives of REPowerEU[1] it is expected that the partnership explores pathways and develops new actions to reinforce R&I investments (and utilisation of R&I results) accelerating the clean energy transition. It is expected that the European Clean Energy Transition Co-Fund Partnership reinforces its ambition considering the revised SET Plan and continues the implementation of its SRIA by setting up joint calls in 2025, 2026 and 2027. In addition, the partnership is invited to setup joint calls without co-funding from the European Union. The consortium that won the grant under topic HORIZON-CL5-2021-D3-01-04 is uniquely placed to submit a proposal to continue the envisioned partnership. With regards to the various activities already undertaken in previous years, no other consortium is able to continue the activities of the Partnership underway without a significant disruption of the ongoing activities. While the grant under this topic should be attributed to a proposal submitted by the coordinator of the consortium funded under topic HORIZON-CL5-2021-D3-01-04, the consortium applying to the present topic may include additional partners and new activities, to be funded by the grant subject to an evaluation, which will take into account the existing context and the scope of the initial evaluation (as relevant), and related obligations enshrined in the grant agreement.

Proposal page limits and layout: described in Part B of the Application Form available in the Submission System. 2. Eligible Countries described in Annex B of the Work Programme General Annexes. A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects. See the information in the Horizon Europe Programme Guide. 3. Other Eligible Conditions The proposal must be submitted by the coordinator of the consortium funded under HORIZON-CL5-2021-D3-01-04 Clean Energy Transition. This eligibility condition is without prejudice to the possibility to include additional partners. described in Annex B of the Work Programme General Annexes. 4. Financial and operational capacity and exclusion described in Annex C of the Work Programme General Annexes. 5a. Evaluation and award: Award criteria, scoring and thresholds The evaluation committee can be composed partially by representatives of EU institutions. If the outcome of amendment preparations is an award decision, the coordinator of the consortium funded under the topic HORIZON-CL5-2021-D3-01-04 will be invited to submit an amendment to the grant agreement, on behalf of the beneficiaries. are described in Annex D of the Work Programme General Annexes. 5b. Evaluation and award: Submission and evaluation processes are described in Annex F of the Work Programme General Annexes and the Online Manual. 5c. Evaluation and award: Indicative timeline for evaluation and grant agreement described in Annex F of the Work Programme General Annexes. 6. Legal and financial set-up of the grants This action is intended to be implemented in the form of an amendment to the grant agreement concluded pursuant to topics HORIZON-CL5-2021-D3-01-04 and HORIZON-CL5-2023-D3-01-18. For the additional activities covered by this action: • The funding rate is up to 30 % of the eligible costs. • Beneficiaries may provide financial support to third parties (FSTP). The support to third parties can only be provided in the form of grants. • The maximum amount of FSTP to be granted to an individual third party is EUR 5.000.000. This amount is justified since provision of FSTP is the primary activity of this action and it is based on the extensive experience under predecessors of this partnership.
