Solahart Program EDGE VPP Further Information
Project EDGE is designed to explore ways that homeowners can benefit from helping the electricity grid when it is under stress. The grid can become unstable when there is either too much demand (e.g. during the evening peak period), or when there is too little demand (e.g. on cool sunny days in areas with lots of rooftop solar).The best way to help the grid during times of peak demand is to move appliance energy use to other times of the day. As part of the Project we will try to minimise your energy use during peak periods where possible. If you have a battery, we will occasionally export some of the stored energy at times when there will be maximum benefit for the grid. During times when there is too much solar in the grid and not enough demand, the most beneficial action is to use your PowerStore to consume more of your own solar power, reduce the amount of solar being produced or draw power from the grid instead. As part of the Project we will occasionally react to extreme conditions with two levels of response:
“Zero export”: where your solar production will be reduced so that there is no power going to the grid, but your household loads will still be supplied using solar power.
“Maximum response”: where solar production will be stopped completely and your connected appliances will be told to draw power from the grid. Because of the number of factors affecting the stability of the grid, there will likely be some days where your system will not be impacted at all, while on other days your appliances may be called upon multiple times. Each time your appliances are controlled as part of the project there may be a small opportunity cost to you in the form of reduced export revenue or the purchase of additional grid energy. Our objective is to keep this opportunity cost to less than a dollar a day on average to ensure that you benefit from participating in the Project.
