Economic compensation model and bidding clearing rules for interruptible load（IL） market are discussed and coordination between IL and generation-side reserve capacity for generation adequacy is emphasized. Inducement fashions for IL can be classified into discount price for electricity with certain blackout risk and high compensation for actual blackout occurrence. Both fashions can be operated under certain market rules. Their different economic properties leave some room for coordination. The paper also points out that the risk cost for generation inadequacy can be expressed by IL cost， which can be added into the objective function for the optimization.
