5 Innovation pressure on CHP operation and/or compensation (1/3) Lack of marketing alternatives Lack of marketing alternatives for plants which are not renumerated by the CHP act Shut down or dismanting Eingespeiste Strommenge [GWh el ] Hocheffiziente neue KWK-Anlagen > 2 MW Brennstoffzellen Hocheffiziente modernisierte KWK-Anlage Hocheffiziente kleine KWK-Anlagen bis 50 kw Hocheffiziente neue KWK-Anlagen 50 kw bis 2 MW Kleine KWK-Anlagen bis 50 kw Kleine KWK-Anl. bis 2 MW (Förderung bis ) Modernisierte Anlagen (Förderung bis ) Neue Bestandsanlagen (Förderung bis ) Alte Bestandsanlagen (Förderung bis ) Jahr der Einspeisung FhG ISE auf Basis der Daten von: eeg-kwk.net

7 Innovation pressure on CHP operation and/or compensation (3/3) CHP plants offer load shifting potential The rising share of fluctuating renewables requires more flexibility with regards to generation and consumption. Especially thermal-electrically coupled systems such as CHP plants offer intersting load shifting potentials.

8 Conditions for market participation (1/4) Spot market Technology - bids have to exceed 0,1 MWh (e.g. 0,1 MW over one hour) - increase of 0,1 MWh - Access to the EEX trade systems (simple: internet based WebAccess) - load XXX measurement every 15 minutes Regulation EEX trading licence: - allocation to an accounting grid /foundation of an accounting grid in - within the control are of a generator equity - Accreditation as clearing/nonclearing member of the ECC - proof of reliability/qualification as a -- - trader

9 Conditions for market participation (2/4) Market for minutes reserve Technology - bids have to exceed 15 MW, increase in 1 MW steps, pooling possible - provision of full power 15 minutes after request (as well as shut down) - Monitoring through TSO (especially run up and power while demanding) - 100% availability % of provided powe - 15 minute measuring load Regulation - approval - as BKV - from plant operators and/or owners - from TSO (Pre qualification, framework agreement) - allocation to an accounting grid

10 Conditions for market participation (3/4) Additional services are supposed to be considered»on top«peak shaving Electricity customers measured by power Load reduction in order to reduce the power price Avoided grid use

11 Conditions for market participation (4/4) Barriers in short Spot market High fixed costs (fees, securities), administrative efforts Market for minutes reserve pay-as-bid market day-ahead market Premium for power back up as Bedingung für Abruf von Arbeit Low call probability Additional services bilateral contracts needed Information deficits

12 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

13 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.

14 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.

15 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.

19 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.
