Home energy storage is the driving force of the future
Beyond rockets and high-end electric vehicles, Tesla’s Elon Musk claims the battery will make a far larger impact on this planet than anything else.
Not only do these batteries – known as “behind the meter” storage – raise the prospect of reducing households’ electricity costs by optimising the time they receive power, they could cut further bills by selling excess power back to the network at times of high demand. They could also provide an emergency back-up if the main grid fails.
Home owners might find this hard to imagine now but Powervault is making this happen:
Powervault’s 2kWh – 6kWh batteries start at £2,500 and are capable of providing about a third of the needs of a typical British home, having charged themselves from roof mounted solar panels or from the grid using off-peak electricity.
