With the removal of the final pylon from the Olympic Park, the ODA outlined today the economic and legacy benefits the two-year powerlines project has delivered, including:

2. Safety is of paramount importance to EDF Energy Networks and National Grid and both companies would like to remind the public that only authorised staff are allowed to go near power lines. The companies warn that all power lines may be dangerous and people should never go close to them as electricity can jump gaps and can kill. Our message is always ‘Look Out, Look Up’ to avoid danger. Both companies are committed to spreading safety advice to children about electricity and our dedicated safety advisers reach hundreds of thousands of schoolchildren every year
3. The powerlines project is a key part of the wider work being undertaken by EDF Energy and National Grid to reinforce and upgrade the power network for east London and the London 2012 Games

The construction of the venues and infrastructure of the London 2012 Games is funded by the National Lottery through the Olympic Lottery Distributor, The Department for Culture, Media and Sport, the Mayor of London and the London Development Agency.

- Two 6km tunnels built beneath the Olympic Park enabling the power needed for the Games and legacy developments to be carried underground.
- Four huge 40 tonne tunnelling machines used.
- Tunnelling work completed in 424 days.
- Olympic Park tunnelling accounted for 85 per cent of the UK’s tunnelling for that year.
- 200,000 cubic metres of spoil created during tunnelling - enough to fill Wembley Stadium - the majority of which is being reused on Olympic Park.
- Complex nature of tunnelling process meant a series of obstacles were encountered during the project, including issues with soil contamination and encountering small ground movements and water ingresses beneath the surface of the Olympic Park
- Tunnelling phase was delivered on time, on budget and with an impressive health and safety record, which was better than the industry average
- Work began in June last year to install 200km of cabling in the tunnels - enough to stretch from London to Nottingham.
- More than 9,000 brackets also installed to carry cabling along the tunnel walls, together with monitoring and ventilation equipment.
- Cabling phase of project completed on schedule in May, allowing testing and commissioning of the new underground equipment to begin.
- Power then switched underground this summer allowing work to remove the overhead pylons and powerlines to begin.
Pylon removal phase
- more than 1,700 jobs and six major contracts awarded, worth more than £200m in total, for the tunnelling, cabling and pylon removal phases of the project;
- pylons up to 30m high removed from the Olympic Park, transforming the skyline of east London for good and unlocking the Olympic Park site for the construction of new homes, sporting venues and essential infrastructure; and
- a new backbone of electrical infrastructure created beneath the Olympic Park to power the Games and the lasting regeneration of the area.
'This £250m project, delivered on time and to budget, has created new jobs for local people and business opportunities for a range of companies and unlocks the Olympic Park landscape for the delivery of new homes, world-class sports venues and essential infrastructure.'
The powerlines project was started by the London Development Agency (LDA) in 2005, ahead of London's successful bid to host the 2012 Games. It was then handed over to be managed by the ODA, working with the LDA as well as EDF Energy and National Grid, the companies that own and operate the overhead lines. The powerlines project has involved three separate phases:
- 52 overhead pylons to be removed - 1,300 tonnes of steel which will all be recycled.
- 130km of overhead wires removed.
- All pylons within Olympic Park boundary now removed, unlocking the landscape.
- Work to remove the pylons on the outskirts of the Olympic Park, through the Lower Lea Valley towards Hackney and West Ham, will be completed in early 2009.
