[3] Preparatory construction work for the development included the extension of the National Grid electricity substation at Walpole, Norfolk, which began in April 2009.

[4][note 1] In June 2010 Siemens obtained the contract for the offshore electrical substation (£101 million).

In June 2012 the consortia obtained financing for the project with £425 million of nonrecourse debt facilities provided from a consortium of 10 banks.

Approximately 75% of the project cost was for the wind farm installation, the remainder for the high voltage electricity transmission link.

[16] The wind farm was scheduled to become operational in the second half of 2012, and be complete by 2013:[17] the final turbine was installed by March 2013;[18] and the wind farm officially opened by Deputy Prime Minister Nick Clegg in August 2013,[19][20] with commissioning complete in September 2013.

[21] The license for the electrical transmission link was awarded to TC Lincs OFTO Limited for £308 million in late 2014.

[22] The scheme has 250 MW of generating capacity, with an additional 20 MW of turbine generating capacity constructed within the nearby Lynn Wind Farm and Dowsing Wind Farm but connected to the Lincs project transmission system.
