TECES is Slovenia’s leading innovation cluster and an internationally recognised coordinator of strategic partnerships and projects in the field of green technologies and energy-efficient solutions. To strengthen development cooperation between civil and defence stakeholders, TECES and the Ministry of Defence of the Republic of Slovenia (Si MoD) established the Slovenian Energy and Environment Partnership in Defence (SiEnE). The partnership serves as an example of effective collaboration between the civil and defence sectors, as well as the successful integration of Slovenian stakeholders into international defence programmes and projects aimed at enhancing energy efficiency and the resilience of critical infrastructure. TECES has gained recognition as a reliable partner and coordinator of international projects under the European Defence Fund (EDF), notably as the coordinator of EDF-2021-INDY and EDF-2024-SENTINEL. As a facilitator connecting Slovenian experts from industry and research organisations, TECES actively participates in numerous initiatives and projects under the auspices of the European Defence Agency (EDA).
