Due to the growth of distributed wind power generation the national grid is now constrained in some geographical areas. This means District Network Operators (DNOs) restrict the amount of power you can export onto the grid.

Biosus can supply an export curtailment system which will allow the client to generate for site power demand and also limit generation to ensure power exported does not exceed the 50kW criteria for micro-generation. These systems have a user friendly interface which track power imported and exported in real time. Various load devices can be connected, allowing devices to be turned on or off when reaching a defined import or export limit.

Biosus Energy have been approved as successfully meeting the required G59 and G100 testing standards for export limiting systems as outlined by the Energy Networks Association.
