This is where solutions like the Arsenal battery come in. Energy storage devices like those at the Emirates Stadium can charge up when renewables are abundant (and so energy is at its very cheapest and greenest). Arsenal can then choose to run a full ninety minute game off their battery and avoid using the grid whenever energy is dirtier, and more expensive.

During the charging period, the system prioritizes charging the battery first from PV, then from the power grid until the cut-off SOC is reached. After reaching the cut-off SOC, the battery will not discharge, and the photovoltaic output will also be normal.
