2021Planning Consent Awarded
Authority: RAE (Regulatory Authority for Energy, Greece) · Licence: Approval of DEDDIE Distribution Network Development Plan 2021–2025 (including upgrades to existing MV submarine interconnections such as Ios–Sikinos)
The Greek energy regulator RAE approved the 2021–2025 Distribution Network Development Plan (ΣΑΔ) for DEDDIE, which includes named reinforcement and upgrade projects on the medium-voltage network such as the improvements to existing submarine interconnections, including the Ios–Sikinos cable link. This decision authorises DEDDIE to plan and implement these network development works during the 2021–2025 period.
Jan 2021Fid Financial Close
For Greek TSO-operated island interconnection projects, there is no separate Final Investment Decision in the commercial sense. The Greek state, through the Ministry of Environment and Energy and the National Recovery and Resilience Plan (Greece 2.0), commits public and EU funding for construction. IPTO/ADMIE, as the regulated transmission system operator, is obligated to develop the interconnection once environmental terms are approved, the project is included in the national development plan, and financing is secured (typically a combination of state budget, EU Recovery and Resilience Facility funds, and EIB loans). The approval of environmental terms and subsequent inclusion in state funding programmes effectively constitutes the investment decision, as the TSO has no discretion to decline once the regulatory and financial framework is in place. This event is recorded as fid_financial_close because the planning consent and funding approval together serve the same function as a commercial FID: they authorise and obligate the TSO to invest in construction. The pattern is analogous to German TSO offshore grid connections where the BNetzA NEP confirmation serves as the de facto FID.
