The Plaid Cymru manifesto is calling for an extra 1% extra of UK GDP, equivalent to £800M, to be spent on Wales infrastructure projects.
The party has a ‘Build 4 Wales’ policy which will provide a specialist infrastructure centre. Key policies include bringing the railways and Severn bridges into public ownership.
The party said, if elected, it will push for electrification of all major rail lines in Wales by 2034, as well as looking at reopening lines, including the one between Carmarthen and Aberystwyth.
Significant infrastructure projects highlighted in the manifesto include a South Wales Metro around the Cardiff area and pledges to push for improvements to the A55, including the construction of a third Menai Bridge. However the party said it does not support the proposed ‘Black Route’ for the M4 and would support ‘Blue Route’ improvements.
Plaid Cymru candidate for Carmarthen East and Dinefwr Jonathan Edwards said in the manifesto: “Lack of infrastructure investment dampens all efforts to boost our economy.”
In terms of energy, the manifesto said the party would introduce the not-for-profit Ynni Cymru which will put its national resources and energy into public ownership. It said: “We will look into establishing local power grids and a Wales-side national energy grid to secure energy transmission in Wales, linking north and south entry points undersea.”
There would also be a focus on tidal and hydro power. The use of underground and undersea cabling will also be promoted, but there will be caution on fracking and any new nuclear power plants will be opposed.
