SSE and Total to offer corporate PPAs from Seagreen offshore farm


Corporate power buyers are to be offered the chance to bid for new form PPAs offered by two energy companies, sourced direct from their 1.1GW Seagreen offshore wind park.

In Seagreen, their £3 billion venture 27 kilometres off the Angus coast, east of Carnoustie and Montrose, Perth-based SSE Renewables and France’s TotalEnergies have revived the ‘auld Alliance’.

Rated at 1.075GW when completed, the farm’s 114 turbines will constitute Scotland’s biggest offshore generator, with a headline capacity said to equal the power needs of 1.6 million homes, or two-thirds of the nation.  SSE holds 49% of Seagreen’s equity, and will manage the installation.

Commercial generation is expected to begin in 2023. The duo aim to secure innovative 5-year supply contracts – half the duration of a standard PPA – with corporate purchasers.  The developers will be advertising for bidders after the summer holidays, they announced yesterday.

Besides shortened PPAs, up to five customers in energy-intensive industries will be able to buy Seagreen’s power in annual blocks of 100MW or 20GWh.

Damien McSweeney, the park’s finance director said its new purchasing options offered an opportunity for large corporates to buy renewable energy that might otherwise be out of their reach.

“We are innovating the offshore corporate PPA model to help energy-intensive businesses hit net-zero targets with ease and speed,” McSweeney added.


  1. A useful development, and the growth of offshore wind is a great success story for the UK. However, I do believe that major energy users should first use on-site solar PPAs, then offshore corporate PPAs for their remaining energy requirement. On-site solar PPAs have greener credentials (it is additional renewable generation), and have the financial advantage of completely avoiding transmission and distribution charges.
