What are the G99 regulations and how do they affect me?

The connection of any form of generator device to run ‘in parallel’ or ‘synchronised’ with the mains electrical utility grid has certain regulations that must be complied with. These regulations are commonly known as the ‘G99’ requirements and apply to Combined Heat & Power units, and Generators being used for peak-lopping, or grid parallel use.

The electricity grid operators (known as DNO – District Network Operators), refer to these units as ‘embedded’ generators, because they are embedded within the electricity grid, as opposed to being at the source of the national grid such as a power station.
