etelligence (1/8) What is etelligence? The research project»etelligence«is a winner of a technology competition»e-energy«of the German Federal Ministry of Economics and Technology (BMWi). Model region Cuxhaven Working group of more than 20 partners under the guidance of utility provider EWE AG Oldenburg supported by
etelligence (2/8) Idea behind etelligence Intelligent system integration of generators and consumers by using modern ICT (information- and communication technologies). etelligence develops and tests a regional market place for electricity, feedback systems, tariffs, incentive programs and control systems, a plug&play ICT infrastructure and international standards.
etelligence (3/8) How does etelligence work? Market place etelligence integrates electricity generators, consumers, energy services and grid operators at a regional market place. Plug&Play ICT infrastructure using modern ICT and international standards a plug&play IT infrastructure for communicating with generators and consumers is established. Intelligent system integration market place and ICT allow for a automated control of generators and consumers.
etelligence (4/8) How does etelligence work? Application Example CHPs in private buildings are enabled to adopt their operation to market prices of the etelligence market in order to compensate fluctuations of wind energy production.

etelligence (8/8) Chances of the etelligence market Chance to offer a holistic market platform for the first time with respect to the products presented. Effective power can be traded between the actors Connection to the EEX market is realised by a market maker. First knowledge on controlling power markets due to short-term trade up to physical delivery Locality of the product offers the possibility to market services especially to DSOs.
