Environmental Information Regulations (EIR) 2004

We publish large amounts of environmental information on our website. However, if you cannot find what you are looking for, you may request environmental information under the Environmental Information Regulations 2004.

How do I submit a request?

Before submitting a request

Before submitting a request, we recommend that you read through the information we publish on environmental information as you may find that the information you require is already publicly available.

For example, you can find information on our environmental and innovation performance over the last 12 months page here

We also publish on our Connected Data website

Our Generation Capacity Register which aggregates technology types at Primary substation level.

  • Our Embedded Capacity Register (all gen 1MW+) including MPANs, are captured in a consolidated format including generator type. Location, capacity and wider key information. Both of the above are updated monthly and provide connected, accepted-not-yet-connected, and offered connections. 
  • We provide Distribution Future Energy Scenarios reports for each local authority area on our website (example attached) (and here). This gives details on expected DER out to 2050 under 4 future energy scenarios.
  • We also publish the shape files covered by our Primary substations to determine geographic coverage.
