DNO Applications in Hertfordshire

Hertfordshire's DNO is UK Power Networks. Connection requirements:

• Below 32A per phase: G98 notification only
• 32A to 80A per phase: G99 application
• Above 80A per phase: Full G99 with potential reinforcement
• Multi-charger installations: Cumulative load assessment

Typical timelines: 8-16 weeks for G99 applications. UK Power Networks operates one of the more efficient DNO processes in the UK.

Solar-Powered Workplace Charging

The strongest commercial EV economics come from solar-powered charging. A Hertfordshire commercial property with 100kWp solar plus 8 workplace chargers can deliver:

• 40-60% solar charging in summer
• 15-30% in winter
• Significant reduction in commercial electricity costs
• Marketing and ESG benefit

Combined system costs run £85,000-£115,000 for a typical mid-size business installation.

Fleet Considerations

For commercial fleet operators, key planning considerations:

1. Vehicle utilisation patterns

2. Charging duration and timing

3. Power requirements (AC vs DC)

4. Spatial planning within the depot

5. Future expansion sizing

Phased deployment is typically more cost-effective than full fleet conversion in a single installation.
