G99 connection
G99 governs the connection of generation equipment operating in parallel with UK distribution networks. The project pathway depends on power, equipment, site configuration and the relevant DNO process.
UK GRID-CONNECTION PLANNING
G99 and G100.
Clear from the start.
Soundon’s iEMS and PCS include functionality to support generator connection and export-limitation design—but every UK project still requires site-specific engineering and DNO acceptance.

G100 export limitation
G100 covers customer export-limitation schemes. Soundon control functionality can support the design, while measurement, fail-safe arrangements and final approval remain site-specific.
PROJECT PATHWAY
From site data to energisation.
- 01Define the system
Confirm PCS power, battery capacity and operating modes.
- 02Review the connection
Existing supply, export limit, protection and site drawings.
- 03Apply to the DNO
Follow the relevant application route with accurate technical data.
- 04Install and prove
Complete settings, commissioning and any required witness test.
SCOPE CLARITY
Integrated functionality is not automatic approval.
This distinction protects the project programme and prevents misleading claims.
