Smart grids and domestic alternative energy production are changing the rules of engagement between energy customers and their suppliers. At the same time, deregulation and a new set of diverse domestic digital media service providers entering the market demand broader and more intelligent marketing strategies. These changes create instability in a market that has been stable for many years. It forces the suppliers, particularly the energy suppliers, to abandon business practices that have long been serving them and adopt a more flexible and agile growth model, an uncomfortable position, particularly for the larger organizations in the sector.
