For those with battery storage it would be useful if this got scheme got extended to include some sort of 'Virtual Power Plant' scheme, where if demand is high batteries could put some power back in the grid and be paid a higher rate than the standard feed in tariff.
I know Tesla Powerwalls are used in VPP's in California, Texas and Australia. Apparently quite helpful for stabalising grid during peak times and can reduce need to switch on the gas peaker power generation plants.
Hell between the above and the 30+ pence difference between peak and off-peak rates payback period on batteries is getting a lot shorter
