What's distinctive about Northern Powergrid
Strong on network reinforcement assessment for installs above 250 kW; frequent earthing arrangement clarification; requires anti-islanding documentation for battery integrations.
For FE college solar projects in North East England and Yorkshire, this means three planning considerations: (1) start the G99 application within the first 8 weeks of project kickoff — the DNO timeline is typically the critical-path item; (2) factor Network Study fees into the Salix energy savings calculation where installs are above 400 kW; (3) prepare the protection coordination documentation in detail with the design package, which speeds first technical response.
