2Subjects Presentation RWTH-Aachen (02.05.2006) Introduction Nuon Definition and reasons for the Magnum ProjectOverall technical data of the Magnum Power StationThe predecessor: the Nuon Buggenum Power StationLesson Learned from the operation of the Nuon Buggenum Power Station
3Electricity customers Green electricity customers Presentation RWTH-Aachen ( )What is Nuon? Nuon is a Dutch energy company, market leader in the NetherlandsElectricity customers100% = 7 mlnGas customers100% = 6.4 mlnESSENTDELTAENECONuonGreen electricity customers100% = 2.4 mlnHeat customers100% = 0.2 mln1) Market share for gas and electricity are based on the number of connectionsSource: EnergieNed ‘Energy in the Netherlands 2004’, Company reports
4Nuon - generation portfolio overview Presentation RWTH-Aachen ( )Nuon is third generator in Netherlands16 ‘grey’ generation assets on 9 premises in 4 clusters; Total installed capacity about MWeEfficient, dominantly gas fired generationProduction of heat for district heating in Utrecht, Nieuwegein, Amsterdam-Zuidoost, and steam for CorusSeveral renewable assets in 7 European countries, dominantly wind; installed capacity about 500 MWeSyngas development and operational experience: Buggenum (coal, 250 MWe), Velsen (BFG, 400 MWe), IJmond – JV Nuon/Corus (BFG, 250 MWe)Cluster AmsterdamCluster OostCluster UtrechtRenewablesNuon - generation portfolio overview
5Presentation RWTH-Aachen (02.05.2006) Why the MAGNUM PROJECT? Establish sound investment decision for the Magnum Power Station.What is the Magnum Power Station?multi-fuel, highly flexible power station;very large capacity (1200 MWe);net efficiency >= PC power station;superior environmental performance;(future) CO2-capture readiness;year 2010/2011: connected to the E-grid;based on the Buggenum power station;“Lessons Learned” incorporated in design.
6Rationale for the Magnum Project Presentation RWTH-Aachen ( )Rationale for the Magnum ProjectNuon must build at least 1200 MWe new power production capacity:replacement of old power stations with rather moderate efficiency;growth in electricity consumption.IGCC (entrained bed technology) offers superior production and trading opportunities:can gasify a multitude of fuels with high efficiency and without operational problems;can therefore adequately respond to changes in fuel market prices;can produce both base load and peak load E-products;can co-gasify large amounts of renewables (subsidies).Best Available Technology for Power Production with CO2-capture:moderate efficiency losses when CO2 is captured;Best Available (Environmental) Technology :SO2 removal: >99 %;NOx-emission: can comply to requirements beyond year 2015;dust: negligible;heavy metals: emissions: Ni: 1.5%; As: 1%; rest negligible.

15Conclusions Presentation RWTH-Aachen (02.05.2006) Nuon regards IGCC as the best option for a future new to build large power station. The reasons are that:IGCC has/is:Superior fuel flexibilityBest Available Technology for power production with CO2-captureBest Available (Environmental) TechnologyNuon is experienced with IGCC-operation:“Lessons Learned” from the Nuon Buggenum Power Station will be fully implemented in the Magnum design
