9 Electricity Market Driving Forces Mass production based technology Weather dependent electricity production Low operation costs Weather dependent electricity distribution Unlimited sustainable, cost efficient energy source But how to keep lights on? Energy storages Storage is a new component in electricity power system. Main goal is to reduce the total costs of system, to reduce the total capacity (investments) of energy system (resource efficiency)) Digitalization Unlimited, low cost potential to control demand (power) on line Efficient use of capacity of energy system Power balance management Improvement oif cyber security together with loacal production and storages Jarmo Partanen
