ScottishPower announced it has formalised a £1.3 billion contract with Siemens Gamesa — the highest value contract ever awarded by the Glasgow company — for 95 wind turbines at the East Anglia Three offshore windfarm.

“The 95 flagship 14.7MW turbines will have a combined capacity of 1,400MW, generating enough green energy to meet the annual demand of 1.3million homes,” said ScottishPower, which is owned by Bilbao-based Iberdrola.

Iberdrola executive chairman Ignacio Galán said: “The scale and ambition of this investment will support UK’s commitment to net zero and energy security.

“East Anglia Three offshore windfarm will bring homegrown green electricity to the grid for 1.3 million homes.

“And, as part of the East Anglia Hub projects, it will also deliver billions of pounds of investment and support thousands of jobs in the East of England and across the UK”.

ScottishPower CEO Keith Anderson said: “This is the highest value contract ever awarded by ScottishPower and it clearly demonstrates our drive and determination to decarbonise the UK.

“Our agreement with Siemens Gamesa is a massive step forward for East Anglia Three, a project that has been more than 13 years in the making. We are now finalising our other contractual commitments so we can all achieve the clean energy future we want – and need.”

East Anglia Three will be constructed in the Southern North Sea, 69km offshore from Great Yarmouth on the Norfolk coast and is part of the East Anglia zone.

The project will support over 2,300 jobs during the two-year construction period and over 100 roles in operation and maintenance over the lifetime of the windfarm.

ScottishPower has already placed contracts worth nearly £70 million with UK companies for EA3 and it is estimated that the company will invest over £2 billion within the UK to support the construction and operation of East Anglia throughout the project’s lifetime.
