The Opportunity

Due to Britain’s ageing electricity infrastructure, Iberdrola’s subsidiary Scottish Power are investing in a multi-billion pound scheme to upgrade the grid both in Scotland and in other parts  of the United Kingdom. A good proportion of this investment is related  to the upgrading of the existing electrical substations and the construction of new ones to link up with the  new greener energy generation. Having manufactured support steelwork for many of these sites previously, either directly to Iberdrola  or via their EPC’s, the opportunity to manufacture and  install the support steelwork and also the  HV equipment that performs the key transmission role was  afforded to us based on our company credentials, the need for more specialist installation teams and the large  size of the project. The substation site serves 96 wind turbines directly, with a generating capacity of 236MW directly and acts as a connector to the adjacent  Markhill site which has 28 turbines with a generating capacity of 56MW. The site is situated in Dumfries and Galloway, 6 miles off the main road, providing major communication and logistic issues.

The Solution

Power System Services manufactured the 66 tonnes of steelwork, including post insulators, HAM structures etc, utilising our CNC laser-cutting, and drilling facilities at our factories in Chesterfield, Derbyshire. The structures were then galvanised and delivered to site.

Power System Services  then deployed an experienced team to site who quickly familiarised themselves with the required techniques to erect this critical equipment. Utilising a few experienced approved sub-contractor personnel and with the guidance of Kirby and Iberdrola, we successfully completed all mechanical erection works within  the 4 month programme  with no accidents, incidents or near misses. Installed equipment included:

Post insulators, surge arrestors, disconnectors, earth switches, marshalling kiosks, circuit breakers, voltage transformers, HAM structures, busbars and earthing of the structures.

The Outcome

The project was successfully completed by Power System Services utilising our modern manufacturing facilities and an installation team comprised of a combination of full time managers and engineers plus a  election of our approved regular tradesmen and operatives from different areas of the British Isles. Our co-operation with the Kirby Group was vital in providing the knowledge and experience required to ensure safe and timely completion of the project.
