Octopus had a trial in the Sprring where they rewarded customers for timeshifting their demand away from the Peak Period when requested. Results were modest and the average loadshift was only 0.7kWh, but across 100k customers that was a larger number.
This now seems to be going ahead in a more formal manner, as reported by the BBC here:

Perhaps potentially of interest to people who can timeshift their export energy? A small extra return on existing facilities.
Suspect that on the whole many BHers can't shift very much energy as we use relatively little. Personally I am totalling about 28-30 kWh per week at present.
As I only have solar not a battery yet, this is not me.
