Transport for London (TfL) has earmarked up to £54 million for the installation of new power Supervisory Control and Data Acquisition (SCADA) systems and related communication network.

The organisation is looking for a single supplier to design, install and migrate a new SCADA system on the London Underground network, as well as to maintain and periodically refresh it. This contract will be awarded in two parts, with a value range between £24 million and £42 million.

“The project aims to provide London Underground with a single, reliable control system for remote monitoring and safe operation of power suppliers on the network,” TfL said in a tender notice.

The new system will replace the existing power network control facility, and replace hardware including Remote Terminal Units (RTUs).

Simultaneously, TfL has put out a contract notice for a power SCADA communication network, worth between £6 million and £18 million.

“The communications network shall interconnect control centres and network communication nodes spanning across the geographical area of central London,” TfL said.

The work under the communications contract includes the design, installation and commissioning of trackside fibre optic cabling and accessories, routers, switches, network management systems and all necessary cyber security infrastructure to interconnect with other TfL control systems or networks.
