The transformative investment we’re making means we’re in the best-possible position to deliver an electricity system which will support sustainable economic growth, benefit the environment in the decades to come, and create significant job opportunities during construction in communities across the north of Scotland.

“In selecting these five contract partners after a fair, open, and competitive tendering process, we’ve secured the ability to deliver our massive programme of investment efficiently and effectively. This transformation will ensure increased resilience, flexibility, and capacity for our 800,000 customers in the north of Scotland.
