The provision of DC supplies at transmission substation sites have almost exclusively been provided by lead acid batteries. New technologies are now emerging which may offer superior performance with reduced maintenance costs, but to date there has been no operational experience within GB.
There are five main objectives of the study:

  • To establish the suitability of a flow battery for providing substation dc supplies as an alternative to conventional lead acid batteries

  • Gain operational experience in the operation and maintenance of an established flow battery technology

  • Test the viability of monitoring conventional and new battery technologies remotely using proprietary software and a data link

  • Validate the round trip efficiency claims for this type of energy storage device

  • Determine the economic and operational benefits of using flow battery technology in existing substation asset replacement programmes.
