Distributed Energy Resources (DER)

If you are considering installing equipment to generate or store electricity likewind turbines, solar panels, batteries or combined heat and power units, we’re here to help. In our industry, DER is also known as distributed generation (DG).

1. Need help with existing solar panels? 

For example: 

  • You need a letter confirming your solar connection to our electricity network so you can change suppliers
  • You want to find out if your installation has been registered with us
  • You want to find out what additional information we need if your installation isn't registered with us

2. Installing Distributed Generation below 3.68kW

For example you want to install: 

  • Solar panels 
  • Electric vehicle charging points
  • Electric heat pumps

3. Installing Distributed Generation rated at 3.68kW or higher

For example you want to install: 

  • Wind farms
  • Solar farms
  • Large scale energy storage
  • Larger scale heat pumps

Products and services for DER owners

Through our smart grid development and innovation teams, we are implementing new products and services to make life easier for distributed generation customers.

  • Flexible connections 
  • Customers can apply for a flexible connection to lower the cost of connection by agreeing to export less energy when there is limited network capacity. 

 

  • Want to discuss your project?

    Discuss your project with us at one of our DER surgeries before completing an application.

  • Appendix G Summary - East of England

    The Appendix G for the East of England informs National Grid Electricity System Operator (NGESO) of the amount of generation per GSP by us. The available capacity is calculated by NGESO, which can lead to the initiation of reinforcement, operational requirements or Load Management Schemes to permit new connections.

  • Appendix G Summary - South East of England

    The Appendix G for the Southeast of England informs National Grid Electricity System Operator (NGESO) of the amount of generation per GSP by us. The available capacity is calculated by NGESO, which can lead to the initiation of reinforcement, operational requirements or Load Management Schemes to permit new connections.
