Infrastructure (Wales) Act 2024

2 Electricity infrastructure

(1) The following kinds of development are significant infrastructure projects—

(a) the construction of—

(i) a generating station in Wales (other than a wind generating station), or

(ii) a generating station in the Welsh marine area,

that is expected to have an installed generating capacity of between 50 and 350 megawatts when constructed;

(b) the extension or alteration of—

(i) a generating station in Wales (other than a wind generating station), or

(ii) a generating station in the Welsh marine area,

where the effect of the extension or alteration is expected to increase the installed generating capacity by at least 50 megawatts, but not so that the installed generating capacity exceeds 350 megawatts;

(c) the construction of a wind generating station in Wales that is expected to have an installed generating capacity of at least 50 megawatts when constructed;

(d) the extension or alteration of a wind generating station in Wales where the effect of the extension or alteration is expected to increase the installed generating capacity by at least 50 megawatts;

(e) the installation of an electric line above ground in Wales that is—

(i) expected to have a nominal voltage of 132 kilovolts and be no less than 2 kilometres long (to the extent it is in Wales), and

(ii) associated with the construction, extension or alteration of a generating station to which paragraphs (a) to (d) apply.

(2) In this section—

• “installed generating capacity” (“capasiti cynyrchu gosodedig”) means the maximum capacity of electricity generation (in megawatts) at which that generating station could be operated for a sustained period without damage being caused to it (assuming the source of energy used to generate electricity is available without interruption);

• “wind generating station” (“gorsaf ynni gwynt”) means a generating station which generates electricity from wind.
