DELAYED +7yr (Apr 2026): Original EEM and CEF-related documentation indicated the Madeira–Porto Santo submarine power cable (Porto Santo Domestic Cable) was targeted around 2021–2022, but EEM’s own project listing ("Projeto Porto Santo Domestic Cable") still shows it only as a co‑financed project with no published construction or installation news up to April 2026, and regional/national news contain no reports of cable-laying between Baía do Faial (Madeira) and Enseada da Morena (Porto Santo). This strongly implies that the planned 2022 installation start has not taken place. Given the multi‑year slip relative to the original 2021–22 target, the early‑development status, and typical 2–3 year lead times from procurement to installation for similar 60 kV island interconnectors, I push the expected start of cable installation to late 2028 as a realistic, conservative assumption. This adjusts away from the earlier optimistic 2021–22 timeline while keeping the project as ongoing and expected, pending an updated official schedule. --- Planning documents state that installation of the 60 kV, approximately 30 MW submarine power cable between Madeira Island (Baía do Faial) and Porto Santo Island (Enseada da Morena) is estimated to take place in 2021 or 2022, marking the start of cable laying activities for this inter-island connection.
