On 16 July 2021, the "Market Reform Plan for Greece" was published, outlining transmission upgrades including the Interconnection of Northeast Aegean Islands, which links Lemnos to the HETS via Nea Santa and then via Lesvos and Skyros to Evia. The plan describes this 150 kV AC submarine cable scheme, with new GIS substations and reactive compensation on Lesvos, and states that commissioning of the overall Northeast Aegean interconnection is expected in 2029, providing a government‑level policy reference for the Limnos–Lesvos segment.
