3.15 G59 witness testing

Relay test 

  • Please note that in accordance with Energy Networks Association Engineering Recommendation G59, permanent normal operation of the generation scheme in parallel either directly or indirectly (through transformer(s) owned by You with UK Power Networks’ distribution system is not permitted until a relay test has been conducted.
  • Only when the relay test sheet has been signed off by UK Power Networks' nominated witness, will we deem the generation to be commissioned.
  • For the avoidance of doubt; on the day of the test the latest published version of the relevant Engineering Recommendation shall apply (unless previously agreed otherwise).
