Major renewable projects

A pipeline of projects

By 2030 the Outer Hebrides is set to have a new 1.8GW subsea interconnector, High Voltage Direct Current (HVDC) converter station and 400kV AC substation, located near Stornoway.

A pipeline of renewable projects at varying stages of consent and development are lined up to utilise the 1.8GW capacity.

Details of each of these projects can be found below.

SSE: Interconnector - Lewis Hub

The Lewis Hub will be a multi-substation connect point for sources of generation, such as wind farms and power stations, and export power to the wider grid. The Lewis Hub has two primary elements, an AC substation and HVDC converter station which are directly linked together.

EuroWind Energy: Uisenis Wind Farm

Uisenis is a proposed onshore wind project c.20km southwest of Stornoway with a potential expected capacity of c.165MW, made of up to 25 wind turbines with a turbine tip height of up to 200m.

The site has an existing consent for the development of the Muaitheabhal Wind Farm, comprising 45 turbines with varying tip heights up to 150 m. Uisenis Wind Farm is located on the same site as Muaitheabhal Wind Farm within the Eishken Estate. If consented, the Uisenis proposal would be built instead of the 45 turbines associated with the Muaitheabhal consent.

Location: Eisgein (Eishken) Estate, Isle of Lewis
