The first building on the Olympic Park has been completed - a new primary electrical substation that will supply electricity to the Olympic Park and the Stratford City development.
The electrical substation is located in Kings Yard in the west of the Olympic Park and will distribute electricity across the Olympic Park and Stratford City site through new electrical networks consisting of more than 100km of electrical cabling. The substation is designed, constructed, owned and operated by EDF Energy through its wholly owned subsidiary Lea Valley Utilities (LVU).
Construction work began in December 2007 and is now complete, making the substation the first building to reach this stage on the Olympic Park. The substation is now operational and will start supplying electricity to the Stratford City site next month, with the Olympic Stadium set to be the first Olympic Park venue to receive electricity early next year. The substation was officially switched on today by the EDF Energy Networks Managing Director Laurent Ferrari and ODA Director of Infrastructure and Utilities Simon Wright.
“Completing the first building on the Olympic Park site on schedule is a major milestone and shows that we are making good progress not only on the main sporting venues for 2012 but also on the backbone of essential new utilities infrastructure,” said ODA Director of Utilities and Infrastructure Simon Wright. “The electricity substation will serve the lifetime of the 2012 project - powering construction work on the Olympic Park site, serving venues during the Games in 2012, and delivering essential new services for generations to come.”
The Electrical Substation takes power from the upstream 132,000 volt electrical network outside the Olympic Park site. Main transformers within the substation then ‘step-down’ the power to11,000 volts so that it can be distributed and used by venues and buildings across the Park and in the Stratford City development.
Sustainability is at the heart of the plans and the construction of the substation reused crushed materials from the demolition of the former Kings Yard buildings in the Olympic Park. The building also includes a ‘brown roof’ which involves crushed materials laid down on a flat roof which allow species to colonise naturally. The brown roof will help enhance the ecological value and biodiversity of the Olympic Park site by attracting local wildlife including black redstarts, a rare bird that thrives on brownfield land.
- More than 130,000 bricks were used in the construction of the substation
- More than 200 piles were installed up to 19m into the ground to form the foundations for the building
- The Electricity Substation will house 132/11kV transformers, each weighing 110 tonnes, as well as 11,000 switchgear and auxiliary equipment
- The building is 80m-long and 14m-wide. The building height varies – the highest point being 15.9m at the Western end and lowest point is 4.875m in central portion of the building
- The substation will distribute electricity across the Olympic Park and Stratford City site through new electrical networks consisting of more than 100km of electrical cabling – enough to cover 250 laps of the Olympic Stadium track
- The substation’s eastern tower was designed to be lower in height to avoid blocking a viewing corridor from the north east corner of the Olympic Park to the Olympic Stadium in south-west, as well as a view out towards central London, to St Paul’s Cathedral and the Swiss Re tower (‘the Gherkin’)
