ABB wins $15-million contract with TVA


Oct 10, 2008

Raleigh, N.C. – ABB recently signed a multi-year agreement with the Tennessee Valley Authority (TVA) worth $15 million to supply 670 Series protection and control relays over the next 10 years. The agreement comes as TVA upgrades and expands its massive multi-state network on the power grid.

ABB will continue as a supplier to provide TVA with electromechanical relays, test switches and related power products, systems and services for TVA’s many substations, switchyards, power plants and connection points, helping TVA to achieve increased energy efficiency, reliability and intelligence.

ABB’s 670 Series Intelligent Electronic Device (IED) is a highly-advanced protective relay for the protection, control and monitoring of transformers, breakers, transmission lines, capacitor banks, generators and buses. These relays allow multi-object capabilities where several primary apparatuses can be protected with a single device, enabling many other intelligent solutions based on functional integration. The IED 670 series supports the worldwide IEC 61850 standard for substation automation, providing extreme intelligence and flexibility that allows for interoperability in communication with other relays and substation automation components.

ABB has been a partner to TVA in the successful deployment and energization of the first U.S.-based multi-vendor IEC 61850 500 kV substation. TVA’s Bradley substation was energized in April 2008 and sets the industry benchmark for capabilities in advanced protection, control and automation using the latest available technology and communication standards.
