In the future we can expect new types of more interactive communications between singlecustomers and groups of customers towards the energy market companies. These can be developas a result of the introduction of individual metering of electricity, and then utilize thisinformation both for information to the customers, as well as different kind of control of thepower system. The information can be through interactive displays where instant and aggregatedenergy and power utilization is presented, but also with a possibility to react to differences inprices by e.g. shutting of some power consumers to avoid high costs. Different types ofinteractions are discussed in the paper.
