Scottish & Southern Electricity Networks — connection process

SSEN is the DNO for the north of Scotland. Within our service area that means Dunblane, Doune, Callander, the rest of rural north and west Stirling district and the Muckhart and Powmill edge; Stirling city, Alloa, Tullibody and Tillicoultry are SP Energy Networks, and Dollar straddles the boundary, so we confirm your DNO from the postcode. Their G99 process runs slightly differently to SP Energy Networks — separate application portal, different commercial team.

G98 vs G99 — which applies?

• G98 (notification only): Single inverter ≤ 16A per phase (~3.68kW single-phase). Notify within 28 days of commissioning — no pre-approval needed.
• G99 (pre-approval): Anything larger. Connection offer issued first, then install, then commissioning. Connection offers typically 8-14 weeks for standard sites; we recommend submitting early to lock in timelines.

Typical SSEN timeline

1. Submit G99 application with single-line diagram + capacity request
2. SSEN accepts application + acknowledges
3. Connection offer issued (connection offers typically 8-14 weeks for standard sites; we recommend submitting early to lock in timelines.)
4. Accept offer + pay any reinforcement contribution if applicable
5. Schedule install + commissioning
6. Send commissioning certificate + MCS cert to SSEN

SSEN specifics

• Application portal: "SSEN Connections" — separate login from SP Energy Networks.
• Standby reinforcement charges occasionally apply for larger commercial sites.
• Off-grid/rural connections require additional engineering studies.
• Three-phase upgrade lead times can be longer in rural north and west Stirling district.
