On 30 September 2015, Elering completed installation of Estonia’s first 110 kV electricity submarine cable between the mainland and Muhu Island across the Suur Strait, corresponding to the Virtsu–Võiküla link. The XLPE‑insulated 400 mm² copper‑core cable was laid and buried in a single length between the shore points to replace an older 35 kV oil‑impregnated paper cable, significantly increasing transmission capacity and improving the security and environmental performance of electricity supply to Saaremaa and Hiiumaa as part of Elering’s western islands supply‑security investment programme.
