G99 Compliance and Protection Settings

G99 Compliance and Protection Settings

Any generator, battery or solar system that runs in parallel with the grid has to meet G99, and the DNO will want applications, protection settings and witnessed tests before it connects.

PCAS handles G99 for standby generators, peaking plant, BESS and solar, from small sites to 20 MW.

Generation connected to the grid, done properly

What we do
  • G99 applications and DNO liaison, including export limited and zero export schemes
  • Protection setting design: loss of mains, over and under voltage and frequency, ROCOF and vector shift
  • ComAp G99 protection configuration and interface protection
  • Export limitation and import limit control
  • Witness testing and commissioning records

Recent G99 work
  • UK wide: G99 protection settings upgrades across 20 MW of generation sites
  • Midlands distribution centre: 800 kVA generator installation with switchgear and G99 testing
  • North West hospital: zero export G99 application for standby generation
