Here is the main text from the email that I just received:
Your Power Move Plus target.
Your personal Power Move Plus target for this event is 0.5 kWh.
Avoid using non-essential electricity between 5pm and 6pm on Thursday 16 November and for every kWh you shift below your target, you’ll receive £3 towards your energy bill.
It is impossible for me to achieve even 1 KWh below the target of 0.5 KWh!
Can any Ovo person, or anyone else for that matter, make any sense of this?
