First, a domestic battery storage system will reduce your energy bills by circa 85%. You have energy stored up, which means you can manage it efficiently. So, you’re less reliant on the grid, and not beholden to peak charges. As well as these initial savings, your battery system will enable you to get smarter about your energy usage over time.
Battery storage is a vital tool that we use to balance the grid and they play a wide range of roles in doing so. The main function is to provide us with artificial inertia and it is stored electricity that can be called upon to provide fast response. We started using battery storage around 2014 and technology has evolved a lot in under a decade.
An installer would simply come and fit your domestic battery storage system, adding an AC coupled inverter to communicate between solar PV, the battery, and the home. So, the power from your existing solar array will charge the battery, the battery will supply the home, and any leftover energy is sent back to the grid.
This is different to other levels of battery storage such as in homes (domestic battery storage) or businesses (commercial battery storage). Meanwhile, battery storage simply refers to batteries which store electrochemical energy to be converted into electricity. So, there you have it.
If you’re a homeowner looking to take control of your energy bill, then battery storage could be the right option for you. Battery storage is a technology that stores energy until it’s needed, so you can use it for your own power needs and save money on your energy bills.
Battery storage at grid scale is mainly the concern of government, energy providers, grid operators, and others. So, short answer: not a lot. However, when it comes to energy storage, there are things you can do as a consumer. You can: Alongside storage at grid level, both options will help reduce strain on the grid as we transition to renewables.
