 In May 2007 , Npower announced plans to build a new £ 2 billion clean coal power station on the site . The proposed station would have generated electricity using three 800 MW advanced supercritical steam , high @-@ efficiency coal @-@ fired units , giving the station a total generation capacity of 2 @,@ 400 MW . This was one of two new coal @-@ fired stations proposed by Npower in the UK . The site was chosen because of its readily available proximity to the national grid , its rail and port links , and its position next to the North Sea , which is useful for both cooling water , and as a potential CO2 storage site , where CO2 could be piped to oil and gas wells , and saline aquifers .
