4 State strategy to provide Security of Supply qregulated infrastructure > System Operator Authority (Svenska Kraftnät) > Transmission and distribution grids > Regulatory supervision of national Regulator > Market mechanisms and rules ( NordPool Spot) qcompetitive market for generation and sales

5 Investments to meet the climatic challenges dollar Investments in Electrical Energy up to /3 to 1/2 of the investments needed in transmission source: World Energy Outlook, 2006 (+ exchange rates corrections to 08)

9 Wind Power Development Scenarios in Sweden q National planning target set to facilitate: 30 TWh / MW q Summary of all identified projects: > MW / 90 TWh q Presently installed capacity: Hydro MW Nuclear MW

10 Economic incentives Swedish system of Green Certificates > Mandatory requirement on electricity consumption > Each MWh in consumption must correspond to a specified volume of certificates > Requirements are defined as annual quotas (% of cons.) > Certificates are issued for renewable production > The price of certificates are determined on a market basis > Present target to reach 25 TWh renewables by year 2020 > Long term stability, the system is scheduled at least until 2035 > Agreement to extend the system to include Norway

Vindparker Fosen statkraft 720 MW Nygårdsfj. 40 MW Nord-Norge: Finnmark: 2900 MW Troms : 680 MW Nordland: 1025 MW Midt-Norge Trøndelag: Romsdal: 2210 MW Møre & 2215 MW Total around 9000 MW Smøla 150 MW 7285 Fræna 65 MW 895 Haramsfjellet 66 MW Haugshornet 75 MW

12 State strategy to provide Security of Supply qregulated infrastructure qcompetitive market for generation and sales qmarket for Green Certificates as instrument to reach sustainability targets

13 Wind development in a broader perspective Wind expansion

14 Extensive wind development scenarios q q Wind capacity may reach levels that are highly significant in relation to presently installed generation capacity Implies a major transformation of the Nordic Power System and its physical characteristics

15 Joint objective of the Nordic TSO:s To develop the Nordic Power system to support the climate and energy policies laid out to reach the EU Commission sustainability targets 20/20/20 at year and beyond that!

16 Impact on central System Operator objectives Balance regulation Load-frequency control Transmission Snitt MW Snitt MW Snitt MW

17 Wind power induced balancing needs Example from Germany Forecasting difficulties Balancing need MW

18 Balance regulation in hydro Efficient, emission-free MWh/h Extensively used today Import / - Export Vattenkraft Vindkraft Värmekraft Kärnkraft Elavändning Tor Fre Lör Sön Mån Tis Ons

19 Role of the Nordic Hydro Power > Real time balance regulation of wind variations > Back up for low wind generation > Central European requests for the regulation capacity

20 Balance Regulation in Hydro Power > The regulation capacity of the Nordic hydro power is extensive but not infinite > The capacity is expected to be used to its full ability > In conflict with local environmental concerns and legally binding constraints

21 Balance regulation in generation and on the demand side Källa: Svensk Energi 21

22 Smart Grids - Demand flexibility

23 Vehicle-to-Grid (V2G) Vision Based on vision from AC Propulsion

24 Market developments > Expanded Balancing market > Volatile pricing of balancing services > Development of the Nordic decentralised balancing concept interacting with the TSO:s central role > Spot market operating closer to real time

25 State strategy to provide Security of Supply qregulated infrastructure > System Operator Authority (Svenska Kraftnät) > Transmission and distribution grids > Regulatory supervision of national Regulator > Development of Market mechanisms and rules ( NordPool Spot) > Development of the TSO driven Balancing market qcompetitive market for generation, sales and balance regulation resources qmarket for Green Certificates as instrument to reach sustainability targets

26 Enhanced transmission capacity needs > Transport of wind generation > Transport of back-up generation > Facilitate use of efficient sources of balancing capacity > Level out generation over large areas

27 Extensive development of renewable generation calls for substantial reinforcements in transmission grids and interconnections Tedious licensing is a serious obstacle
