DNO, Grid & UK Electricity
Grid-aware deployment within the realities of the UK electricity system.
Distribution Network Operators regulate local export capacity.
In the UK, Distribution Network Operators (DNOs) manage local electricity networks and determine export limits for distributed generation.
Residential solar and storage systems must comply with:
- G98 / G99 connection standards
- Export limitation requirements
- Local capacity constraints
Deployment feasibility is location-specific.
Grid capacity is not uniform across regions.
Export is constrained to protect the network.
Under the standardised baseline:
- All systems operate under 3.68kW export limitation (G100 control)
- Self-consumption is prioritised via storage
- Surplus export is governed
Export limitation reduces:
- Reinforcement exposure
- Voltage rise risk
- Clustered deployment constraint
This control mechanism is structural, not optional.
Uncontrolled clustering increases reinforcement exposure.
Large volumes of distributed generation can trigger:
- Network reinforcement requirements
- Export curtailment
- Deployment delays
Glow Collective mitigates this risk through:
- Controlled export limitation
- Deployment sequencing
- Clustered modelling review
- Early DNO engagement
Grid interaction is designed into the programme.
Grid awareness determines scalability.
Residential decarbonisation at portfolio scale requires:
- Regulatory compliance
- Export governance
- Conservative modelling
- Coordinated DNO interaction
Infrastructure discipline protects long-term programme viability.
Grid constraints are structural.
Programme design must account for them.
