Greater Manchester Combined Authority, with Transport for Greater Manchester, has awarded Siemens with a long term service contract for the maintenance of traffic signalling equipment across all ten districts of Greater Manchester.
Transport for Greater Manchester said the service contract is designed to secure substantial energy savings and reduce carbon emissions.
Siemens will carry out the work under the guidance of Transport for Greater Manchester.
TfGM claims the technology used by Siemens will reduce associated energy bills by 60% over the life of the contract which will deliver up to 97% availability of more than 2,000 traffic and pedestrian signals.
The technology includes additional equipment such as variable message signs, road safety cameras and access control systems.
The contract will run for a minimum period of 15 years, with a possible five year extension. The value of the contract was not disclosed.
TfGM said the programme in total allows for up to 60,000 signal aspects to be upgraded or retrofitted with LED signal heads and the replacement of over 500 signal controllers.
David Leather, chief executive of Transport for Greater Manchester, said: "This contract presented a major opportunity to secure a deal that would deliver not only financial savings but gains in lower energy and carbon emissions over a long period.
"It is also one of the first examples of our ability to oversee important highways issues at a strategic, regional level in our new role as Transport for Greater Manchester – so it was very important to get the right package together.
"What we have achieved is something that will effectively cut our energy bills by almost two thirds and which will also result in some of the latest technology being installed on our network that will offer real benefits in maintenance and reliability.
"We are very confident in the future delivery of this new service contract with Siemens and the capabilities of the company's maintenance teams, and we look forward to a productive and lasting working relationship."
The Greater Manchester Combined Authority was launched in April. Transport policies that affect the ten districts of Greater Manchester are set by the Greater Manchester Combined Authority and its Transport for Greater Manchester committee.
