Initially, ESS installation might make you pay a premium. While in the long term, there is no doubt that you return can offset costs.
For the family unit, home storage can reduce the cost of electricity by increasing the proportion of self-generated and self-consumption, participating in auxiliary services, etc., and at the same time, it can be used as an emergency backup power supply in the face of major disasters and other factors that lead to the middle end of the grid power, improving the reliability of home power supply.
For the grid group, the rapid increase in the proportion of VRE (Volatile Renewable Energy) will further widen the difference between the power generation curve and the power consumption curve. Configuring energy storage can transfer power in time to help the grid balance power generation capacity and power demand.
Take home storage as an example, the graph below is Economic Calculation of Major Home Reserve Countries in the World
