National infrastructure projects in the UK

The biggest schemes in the country are decided nationally, not by your council: solar and wind farms, reservoirs, roads, railways, power lines and pipelines. Here they are, with each one's stage and site boundary.

12 projects in play in Northern Ireland, including 5 at pre-application.

How national projects are decided

Projects above certain sizes, such as a solar farm over 100 megawatts, a reservoir holding over 30 million cubic metres or a new motorway, are "nationally significant". The promoter consults locally, then applies for a development consent order. An independent panel examines the application and recommends a decision, and the Secretary of State decides. Councils are consulted but do not decide.

"In play" means at pre-application, in the formal process, or decided in the last three years.

Housing schemes, however large, are decided by the council. See the largest housing developments in planning.
