The business model typology presented here is directly related to the energy storage activities commonly seen as business. The most important aspect to be debated is whether Transelectrica could manage such business. The related characteristics of such business, the limits and the necessary degree of adaptability are notably described. The paper reviews the general models for the energy field and then slightly modifies the business models for a transmission system operator like Transelectrica. Its option leads to the network of storage capacities, seen as power reserve networks that can replace or overlap the classic power reserves.
