To safeguard the quality of electricity to each community, we have set a limit on how much rooftop solar our electricity system can accommodate in each town without disrupting supply to our customers. This is called hosting capacity.
To make sure we can continue to offer safe and reliable power supplies to all our customers, Horizon Power must approve all rooftop solar system applications before they connect to our network.
Generation management devices (like Feed-In Management or FIM) help to overcome this challenge by controlling the electricity output of your rooftop solar.
Feed-In Management (FIM) is a type of generation management. A FIM device controls the amount of energy that your solar energy system feeds into the grid, which is especially important at times when excessive energy flows back to the power station, creating a risk to the power supply of the town.
In many of our towns, smaller sized ‘Basic Micro EG’ solar energy systems can only be installed if it is provisioned for FIM. In addition to your panels and inverter, you will need to install a small power outlet and box so the system can be retrofitted with a FIM device at a later date.
Please discuss the cost to install the FIM outlet and box with your solar supplier as this may vary, depending on your location and installer.
If your system is provisioned for Feed-In Management and we later determine that a FIM device is required, we will retrofit your system with a device and it will be at Horizon Power’s cost. We will contact you to discuss any changes to your renewable energy system before it takes place.
If you have a FIM device installed, Horizon Power is able to control the level of production of your solar energy system. However, we will only limit the level of production of your system in response to a risk to the security and reliability of the power system.
Horizon Power is unable to compensate customers for any loss of production associated with Feed-In Management (FIM). Horizon Power’s minimal use of FIM will enable more homes and businesses to meet their energy needs through the installation of rooftop solar.
We may undertake audits of your installed system for compliance with our Technical Requirements.
