In 2004 Powerteam was awarded the contract to construct the largest 220/110kV substation in Ireland at Corduff, Co. Dublin for the Electricity Supply Board (ESB). This was a large, complex and prestigious project for ESB. We were awarded this contract not only on the basis of our competitive price but also because we had a proven track record in previously delivering other high quality projects for ESB, together with experienced and highly competent staff with an impressive safety record. The project required us to use leading edge technology using Bay Controllers linked by fibre optic cable. We were responsible for the entire electrical equipment fit-out, covering installation of: steelwork, circuit breakers, busbars, protection panels and associated multicore and fibre optic cables together with all pre-commissioning. In addition we had responsibility as Project Supervisor Construction Stage (PSCS). Over a 14-month period, we constructed and commissioned over twenty 110kV and 220kV double busbars bays; line bays; bus coupler bays; sectionalising bays and associated transformer bays. The station has a numerical substation control system (SCS) with a distributed control and protection scheme and protection schemes on both the 110kV and 220kV busbars. At the peak of the contract 30 staff were engaged on the project.
In 2004 ESB awarded Powerteam the contract to construct a further 220/110kV (16 bay) substation at Srananagh in County Sligo. The substation has the capacity for two 250MVA 220/110kV transformers; 220kV & 110kV feeder bays; 220kV and 110kV coupler bays. Our scope of works was similar to that at Corduff covering the entire electrical equipment fit-out with installation of steelwork, circuit breakers, busbars, protection panels and associated multicore and fibre optic cables together with all pre-commissioning. Again we had responsibility as Project Supervisor Construction Stage (PSCS) and this project we were also responsible for the substation earthing installation. Both the Corduff and Srananagh projects emphasise our ability to project manage and deliver two large complex projects simultaneously to exacting quality and safety standards, with both coming in on budget and on time.
This was one of our first major projects for WPD. We were responsible for replacing four 132kV circuit breakers with air-blast equipment and associated control and protection.
In 2005 ESB awarded Powerteam a framework contract to refurbish and upgrade seven 38kV substations – Ballinderry, Newport, Killybegs, Birr, Baltinglass, Kilcock and Ballyconnell. All sites were live and ‘in service’, containing exposed busbars and conductors. As a result were we are working in an environment with very stringent safety requirements. To undertake this work ESB required a contractor with competent, experienced staff authorised to work in such conditions. Powerteam were responsible for:
At the height of the contract all seven sites were being managed simultaneously with each at a varying stage of completion. This contract highlights Powerteam’s strength in managing a complex programme of work involving numerous client and supplier interfaces at multi-site locations.
In mid March 2006 SSE awarded Powerteam the contract to refurbish their Charleston 132kV grid substation in Dundee. This substation was a key point on SSE's network and, as such, they requested that we commence work as soon as possible. We mobilised and were on site for the first week of May 2006. Powerteam was responsible for delivering a complete turnkey solution covering:
In early 2007 SSE awarded Powerteam a five-year framework contract for the construction of new and refurbishment of existing 132kV substations throughout their Scottish-Hydro Electric region. We are responsible for delivering a complete turnkey solution covering:
This type of contract illustrates our ability to provide turnkey solutions and manage multi-site contracts while delivering the projects safely, on time and to budget.
