If you wish to connect a generator that is used to supply or sell electricity which includes Wind Farm, Landfill Gas, Solar Power and Combined heat & Power (CHP) facilities, please see here. Such generators may be used to supply or sell electricity via the national grid.

Gate 3 - Renewable Generation Group Processing

Gate 3 is the third renewable group processing directive proposed by the CER. For information on the progress of the Gate 3 Projects please see the Generator Statistics Section.

Parallel Connected Generators

For information on Connecting a generator that operates in parallel with the electricity network please see here. This information is relevant to businesses that want to reduce their electricity import by having their own source of power, or for peak-lopping or peak-shaving schemes. Such generators cannot be used to supply or sell electricity via the national grid.

Standby Generators

Information about connecting a standby generator is available here Standby generators are used by businesses that require emergency generation. They cannot be used to export or sell electricity onto the electricity network. In addition, they cannot operate in parallel with the electricity network.
