New sub­sta­tion to re­place cor­roded fa­cil­ity on coast

Plan­ning: Elec­tric­ity firm seek­ing per­mis­sion for project at gas ter­mi­nal

The Press and Journal (Aberdeen and Aberdeenshire) - - NEWS - BY RE­BEKAH MCVEY

Work has been planned to cre­ate a new elec­tri­cal sub­sta­tion in a north­east town as the ex­ist­ing equip­ment has been cor­roded after be­ing blasted by “ex­treme coastal con­di­tions” for decades.

The sub­sta­tion at the St Fer­gus gas ter­mi­nal, near Peter­head, was built in 1975 and has been de­scribed as an im­por­tant part of the Scot­tish net­work – pro­vid­ing a con­nec­tion point for var­i­ous crit­i­cal oil and gas in­fra­struc­ture and mul­ti­ple wind farms.

The op­er­a­tor, Scot­tish Hy­dro Elec­tric Trans­mis­sion plc, is seek­ing per­mis­sion from Aberdeen­shire Coun­cil to build a re­place­ment on land ad­join­ing the ex­ist­ing site.

A de­sign state­ment lodged along­side the ap­pli­ca­tion ex­plains that re­cent leg­isla­tive changes mean a new plant would have to be cre­ated.

It states: “The need for the pro­posed devel­op­ment is be­ing driven by the need to re­place two 132/11kV trans­form­ers within the ex­ist­ing sub­sta­tion.

“The ex­ist­ing trans­form­ers were man­u­fac­tured in 1975 and are reach­ing the end of their op­er­a­tional ex­pec­ta­tions, trig­ger­ing the need for them to be re­placed.

“In ad­di­tion to the age of the sub­sta­tion equip­ment, the ex­treme coastal en­vi­ron­ment seen at St Fer­gus has also in­flu­enced the plant’s longevity.

“A con­di­tion-based as­sess­ment has found there to be cor­ro­sion present at the trans­form­ers.

“Due to changes in reg­u­la­tions, it is not pos­si­ble to in­stall the re­place­ment trans­form­ers in the same lo­ca­tion as those cur­rently in use.

“This is due to the trans­form­ers now hav­ing to be housed in­side a build­ing given their lo­ca­tion within 2km of the coast, and in­creased fire safety re­quire­ments.

“The new site be­ing lo­cated out­side the ex­ist­ing se­cu­rity com­plex will al­low ease of ac­cess dur­ing the con­struc­tion works and over the life­span of the as­set on site.”

The pro­posal is for a plat­form area, a con­trol build­ing, as­so­ci­ated plant and in­fra­struc­ture, an­cil­lary fa­cil­i­ties, an ac­cess track and land­scape works.

If the sub­sta­tion is given the go-ahead, a new ac­cess road will be cre­ated off a stretch of the A90 be­tween Peter­head and Fraser­burgh to al­low con­struc­tion ve­hi­cles site.

It is an­tic­i­pated the build­ing of the new site will take place over 18 months, with work dur­ing the day­time, seven days a week.

The area ear­marked for the pro­posed site is cur­rently be­ing used for agri­cul­tural pur­poses, but an en­vi­ron­men­tal ap­praisal states that is “of lim­ited en­vi­ron­men­tal value”.

Doc­u­ments also state there will be “neg­li­gi­ble noise im­pact” dur­ing the project. to ac­cess the
