Grid Customers Facing Increasingly Complex Grid Transmission Systems Turn to GE’s Fixed Series Compensation (FSC) Systems

Paris, FRANCE — February 6, 2019 — Today’s grid transmission system is becoming increasingly complex and expected to carry bulk power in ways it was never originally designed to do. GE Power’s Grid Solutions business [NYSE:GE] today spotlighted recent Flexible AC Transmission System (FACTS) wins, specifically related to its industry-leading Fixed Series Compensation (FSC) technology that are helping customers navigate the evolving energy landscape. Totaling more than $60 million USD, these contracts reflect grid customers’ confidence in GE’s innovative FACTS solutions.
GE’s Fixed Series Compensation system allows utilities to cost-effectively increase the power transfer capabilities of both existing and new transmission lines, with reduced transmission line losses and overall improved power grid stability. Fixed Series Compensation (FSCs) systems make transmission lines behave as if they are physically shorter, thus giving them an increased ability to carry electric power over longer distances.  Recent grid customer contracts for GE’s FSCs include the following:

  • LS Power DesertLink: A 500 kV FSC bank will be installed to increase the capacity of a new transmission line to enable the import of more renewable power into California.
  • Idaho Power Boise Bench: Upgrade of two existing banks at the Boise Bench substation.
  • AEP Kanawha River Project: The 345 kV series capacitor is used to help maintain the reliability on the transmission grid and allows flexibility during maintenance and construction outages. Specifically, the 345 kV Series Capacitor Bank assists in alleviating an Interconnection Reliability Operating Limit (IROL) constraint under certain system conditions and can also assist in mitigating system impacts from Geomagnetic Disturbance events.  
  • Large electric Wind Developer: GE’s FSCs addressed this customer’s need to build two transmission lines to connect the wind farms to the grid.  By adding the Fixed Series Compensation solution, they were able to increase the capacity and ultimately only had to build one transmission line to connect to the grid. 
  • Large electric TSO in Pacific Northwest: Expansion of existing substation in Oregon to interconnect Avangrid’s planned Montague Wind Power Project to Federal Columbia River Transmission System (FCRTS).
  • Large electric TSO in Pacific Northwest: Upgrade of existing facilities to provide interconnection capacity for new large load addition requests in the central Oregon area.
  • Eletronorte Miracema: Upgrade of existing facilities to support increased power flow through the North-South Interconnector in Brazil.
  • Neoenergia: New transmission line with FSC banks to support expansion of the North-Southeast and North-Northeast interconnections in Brazil and help dispatch energy and provide for future wind power projects.  

These projects are utilizing new technologies that have proven to benefit the customer through cost-savings and improved safety, among other things. This includes GE’s newly developed polymer-housed metal oxide varistors (MOVs), which improves cost, lead time and personnel safety as well as a new capacitator factory that produces a 22-inch tall fuse-less capacitor design (normally 13.5-inches). This investment allows GE to design capacitor stack-rack equipment packages that cost less than the traditional design and reduce platform space requirements, bridging the economic competitive advantages of large internally fused capacitor units while retaining all of the operational and technical advantages of fuse-less technology.
“Demands on transmission systems continue to grow as new power generation sources continue to develop in new locations around the world and especially in North America. The quality and reliability of GE’s products combined with the outstanding work from our project teams is key to our continued success,“ said Emanuel Bertolini, Region Leader Americas at GE’s Grid Solutions.
GE is a worldwide leader in executing and delivering series compensation projects, with more than a century of experience designing transmission networks including the first series compensation project in 1928. Today, GE has led the industry by delivering over 40,000 Mvars of series compensation systems in the last six years, providing superior systems through innovative products that result in project cost savings, and increased quality and reliability.
