1.5 GW wind – 25% of Danish peak
12.50: 400 MW offshore out
01.57: 400 kV internal out
02.41: 400 kV to Germany out
03.42: 150 kV substation out
04.20: 400 offshore online
06.15: situation normal
1hr 45 mins: 1.5 GW
15 mins. 600 MW
DK peak: 6.1 GW
Traffic accidents block roads – Germany and DK
Controlled shutdowns (to avoid sudden shutdown)

6. WEST  Requested CHP production Real CHP production
1hr 45 mins: 1.5 GW
15 mins. 600 MW
DK peak: 6.1 GW

7. EAST  Not impressed… Requested CHP production Real CHP production
1hr 45 mins: 1.5 GW
15 mins. 600 MW
DK peak: 6.1 GW

8. US CONTEXT US = west Denmark? East? Electricity systems = familiar
Energy systems = complex
Laissez faire: Mind your own business/sector
Can you trust distributed energy resources?
