District cooling - sustainable energy to rely on

  1. 1. Sustainable energy gy to rely on Jenny Dahlberg Fortum 1
  2. 2. Fortum- your energy partner Fortum is a leading energy company with 14 000 employees f l focusing on th Nordic countries, i the N di ti Russia and the Baltic Rim area. Position in the nordic market # 1 Distribution # 1 District heating # 1 District cooling # 1 El t i it sales Electricity l # 2 Power generation 2
  3. 3. g/kWh 0 1,200 200 400 600 800 1,000 3 DEEI Dra ax RWWE Energi E2 E Källa: PWC och Enerpresse 2005 EDDP Union Fenos sa CEEZ Edisoon Endessa Scottish& Souther rn Essennt E.ON Elsamm ENEEL Vattenfaall Electrabeel PVOO Iberdrolla CO2 emissions – European companies Verbunnd Fortum m British Energgy EDDF Statkra aft Fortum has one of the lowest CO2 emissons in Europe
  4. 4. Electricity distribution The power supply in the Stockholm area consists of a 220 kV ring structure, structure owned by Fortum Five primary substations Fortum is capable of delivering 220-33 kV system voltage all around St kh l d Stockholm Fortum can supply the electricity with redundancy from local elctricity production 4
  5. 5. Procurement of electricity • Physical delivery of electricity – used in your daily operation –Price risk –Volume risk (operational) Volume –Political risk • Fi Financial h d i of purchase price – t secure your i l hedging f h i to business result –Customise purchasing and p p g portfolio strategy gy –Customise risk manual according to risk policy –Trade with physical and financial contracts

  7. 7. District heating - an environmental success story Fortum's reduced emissions in Stockholm since 1980: -60 % of CO2 60 >95 % of SO2 >80 % of NOx 70 % renewable fuels 14% 16% Sea 3% Waste Industrial waste 12% Solid bio fuels 11% Bio oil Electricity 9% 13% Fossile oil Carbon 22% 7
  8. 8. District heating For Data centers the need for heating is minimal and Fortum can, instead, buy surplus heat from the centers 8
  9. 9. District cooling in Stockholm - largest in Europe 570 points of deliveries 350 MW capacity p y 400 GWh production/year 170 GWh sept-april deliveries from 8 kW to 11 MW 9
  10. 10. District cooling- This is how it works 4 2 3 1 1. Cold water from the bottom of the sea is used to cool down the DC (district cooling) water that circulates in a close The sea water is then returned to the sea. 2. 2 The heat in the warmer water in the DC return pipe can be recovered to the DH system via heat pumpspumps. By this simultaneous heating and cooling all energy in the cooling system will be recovered. 3. During the nights when there is excess capacity from free or waste cooling production the storage is used. 4. The low temperature in the DC system is transferred to the internal system in the connected buildings. The internal systems are then distributing the cooling capacity within the buildings. 10
  11. 11. Why District cooling? Low intitial investment cost ( -75 %) Minimal operation and maintenance costs ( -90 %) Reduces the electricity consumtion (- 95%) Reduces the need of cooling water (-100 %) ( 100 Reduces the space needed for installations Realiable delivery - availibility of 99,7% Low financial risk- up to ten year individual contract District cooling is climate neutral - increases the environmental p o e of the ac ty profile o t e facility 11
  12. 12. Clients with critical cooling needs In Kista, the "Silicon Valley of Sweden" - approx. 60 % of all district cooling energy is used for server halls. Approx. 50 % of all district cooling clients in Stockholm also use district cooling for local server halls in office buildings buildings. Other examples of clients: DNEX - printing plant Stockholm Globe Arenas - concert arenas for up to 44 000 visitors TV4 - television production & broadcasting company Stockholm International Fair - 70 000 sq.m of exhibition area Karolinska Institutet - medical lab 12
  13. 13. District cooling - Still growing • Expansion driven by client demands. The distribution net expands with growing need för capacity. The production is increased with capacity minimum affect on the environment. • F t Fortum Värme has the knowledge and t h i Vä h th k l d d technique t build new to b ild production sites and distribution system if there is a increased demand in the market. • The choice of method of production depends on local conditions 13
  14. 14. Current project - cold water storage in Hornsberg To increase the capacity in Stockholm, a 40 000 m3 cold water storage is being built. It will be taken in operation in november 2009 and used as a day and night storage. 14
  15. 15. IBM and Fortum, a fruitful collaboration IBM and Fortum has a long relationship. g p In Kista, IBM has sold surplus heat, from their data center, to Fortum since 1997 Together we can make use of energy that 1997. would otherwise be wasted. In 2008, district cooling was installed at the IBM data center 15
  16. 16. IBM - thinking green Since 1967, IBM has had a corporate policy of protecting the environment and conserving energy 1997, IBM became the world's first major multinational to have earned a single worldwide registration t th ISO 14001 d i l ld id i t ti to the Environmental Management System (EMS) standard. 16
  17. 17. IBM Chosing district cooling- questions A choice of technique not previously known to the owners - IBM in Sweden, together with Fortum informed about the simplicity i S d t th ith F t i f d b t th i li it and reliability of the technique How would th maintenance ti H ld the i t time b affected? be ff t d? -The maintenance time will be reduced due to less complicated technique How reliable is district cooling? - Fortum guarantees full delivery of district cooling 99,7% of the year. If a shut down is necessary, Fortum have a dialog with the client. Back up systems are needed though, as with all types of cooling. 17
  18. 18. IBM Chosing district cooling The main reasons for IBM to chose district cooling were: environmental issues less maintenance better economy 18
  19. 19. Cooling and heating - make it climate neutral today District cooling from Fortum is climate neutral today Fortum´s vision is to a so have a c a e neutral p oduc o o o u s s o s o also a e climate eu a production of district heating in 2020 In the mean time - customers can purchase climate neutralisation of their use of district heating For the percentage of production that is not climate neutral today, we compensate with CDM-projects. CDM - Cl Clean D l Delevopment M h i t Mechanism i CO2 - reducing projects is d i j t defined by the Kyoto Protocol and the Framework Convention on Climate Change CDM - projects are made i countries th t l k a sustainable j t d in t i that lack t i bl energy solution. 19
  20. 20. Conclusion Fortum - your energy partner for data centers Electricity distribution y Procurement of electricity Procurement of certificates for renewable electricity District heating District Di t i t cooling li Purchasing of surplus heat Making your data center climate neutral 20
