A project deed should oblige the private party to maintain its own contingency plans. The allocation of risk to the private party also provides commercial incentives for the private party to develop its own contingency framework. It is important that both parties have a basic understanding of one another's plans for these events. This way, should services be interrupted, they are not working at cross-purposes in seeking to restore the services or mitigate the effects of an adverse event. Where a degree of coordination appears necessary, the parties should also cooperate in testing their contingency plans.
