Grid to battery KWH increased

I've noticed that there has been a sharp increase in power from grid to my GivEnergy battery compared with the previous year (9 fold increase). Any reasons why?

Has there been a corresponding increase in energy from the battery? Do you have any automations in play like PredBat, GivTCP, WonderWatt or the GivEnergy Smart Tariff card? Are you using a tariff like Intelligent Octopus Flux where your supplier controls the battery? Have you signed up to any Demand Flexibility Services like Axle VPP (also known as GivBack).
