Find the right connection for you
Introduction to Small Generation Installation (SGI)
Small Generation Installation (SGI) is an Installation that comprises one or more Low Voltage Power Generating Modules each with an Intrinsic Design Capacity of no more than 32 A and where the aggregate Registered Capacity of all the Power Generating Modules is no more than 60 A. The term Small Generation Installation replaces what was referred to as Microgeneration. In recent years, there has been a large increase in the number of applications for these types of connections to our network. This is mainly due to technological advances, environmental issues and new government policies and incentives.
Appointing an Installer
To progress with your connection, you must contact an accredited installer (or equivalent) to arrange your generation connection for you. They will usually contact us on your behalf (although you may do this yourself), arrange all documentation and will generally keep you informed of what actions you may need to take. A list of installers can be found here.
Connecting to our network
Once you have chosen your preferred type of generation, your generator will need to be connected to our network either through your existing supply or through a new connection. The size (kW) of the generator(s) will dictate which connection process you will need to follow.
-
Installations up to 3.68kW per phase at more than one property
Connecting microgeneration onto multiple electricity supplies -
Installations above 3.68kW per phase but 50kW or less
Connecting large generation onto single or multiple electricity supplies -
G99 Fast Track Process
Available installations onto a single-phase connection whereby inverter capacity of 3.68kW Generation and 3.68kW storage per phase and total export limited by G100 device to 3.68kW. -
