London 2012 Electrical Infrastructure Case Study

London 2012 Electrical Infrastructure Case Study

Client: Olympic Delivery Authority

Value: £85M

Forms of Contract: NEC Option A, UKPNS Section 22 and Concession Agreement

Programme:  November 2007 to March 2011


The ODA and Stratford City Developments Ltd (SCDL) entered into an agreement for the shared use of the electrical infrastructure to supply both the Olympic Park and the Westfield development. This necessitated the construction of a primary substation with three 132kv/11kv transformers complete with two new 132kV connections and an 11kV distribution network.

Due to the deregulation of the electricity industry the construction of the Primary Substation was deemed as contestable works thereby enabling it to be competitively tendered. The design and build contract was won by UK Power Network Services (UKPNS) and was awarded as a NEC Option A to the value of £13.9m. The project was completed accident free in less than 2 years which had never been previously achieved on a substation of this size.

As the connection of the two 132kV circuits were non contestable the ODA and SCDL entered into a regulatory Section 22 contract with UK Power Networks (UKPN) worth £14m. This necessitated managing the interfaces between the regulated and unregulated divisions of UK Power Networks with two different contracts.

In May 2009 the ODA and SCDL entered into a bespoke Concession Agreement with Lea Valley Utilities (LVU) a wholly owned subsidiary of UKPN that was formed for the delivery of the 11kV infrastructure throughout the Olympic Park and the Westfield development. As part of the legacy strategy the existing contracts with UKPNS and UKPN were novated to LVU. In return for LVU’s investment they were granted exclusivity as the sole supplier of electricity on the park as an Independent Network Operator (IDNO).

LVU’s scope of work was to deliver over 130 substations and 99km of HV cabling through over 700 different principle contractor areas to supply all the venues.

Delivery challenges:

  • Numerous statutory consents and contractual approvals
  • Complex interface arrangements coupled with diverse commercial arrangements
  • Large number of stakeholders with varying interests and influence
  • Complexities arising out of operating at several work places simultaneously
  • Complex programme management to ensure timely delivery across multiple sites
