Damaged substation equipment will take months to replace, expert warns

The substation fire that forced the airport to close has been described as "really unusual" by an energy expert.

"It looks like the extent of the fire has damaged some of the equipment," Tim Green told our presenter Anna Jones, adding the airport would have multiple electrical routes as well as backup generators.

Green said the substation was "one of the large ones in the country" and at least one of its three transformers, key parts of the substation, has been "very badly damaged".

He explains the transformers take a long time to order, and it's unusual to carry a stock of those, meaning it will likely take a long time to repair the damage to the substation.
