The Price Responsive Discovery event contains a load amount and a price. The price is the maximum bid acceptable, lower offers are requested. If the flexibility supplier can achieve the event requirements they respond with an ‘opt-in’ message and the offer price they are willing to pay. If they cannot achieve the event at or below the bid price they respond with an ‘opt-out’ message. Unsuccessful offers receive event ’cancellation’ messages. If the event remains live, the offer has been accepted.
