Morgan, from the same applicants, also 1,500 MW and 96 turbines, received its DCO on 29 August 2025. In January 2026 EnBW pulled out of both projects: Mona continues under JERA Nex bp, Morgan is halted. At 19.0 km, Awel y Mor with 775 MW is approved, and at 24.3 km Gwynt y Mor has been operational since 2015. Its 3.6 MW turbines are more than four times weaker than Mona's 15.6 MW machines, which stand up to 324 m tall. The nearest postcode districts: Llandudno and Colwyn Bay.
