Future energy markets: how and where?
6. If frequency falls outside the limits, the risk of
system collapse increases
7. Generation structure in the Nordics is becoming
more variable and import-dependency increases
8. Cold winter days with tight demand-supply can
be challenging especially in case of failures

P = Available capacity for market,
TSO reserves excluded
*) 70 500
C = Peak demand **) 72 100
B = Balance without power exchange - 1 600
9. Most of the inertia in the Nordic system comes
from thermal power plants
10. Inertia resists frequency changes - small inertia
means higher risk of blackouts
Small inertia
Normal inertia
Frequency
Time
Fault, e.g. tripping of a large production unit
11. Generation inadequacy has started to cause
concerns elsewhere too

12. A new German word "Dunkelflaute" has entered
the electricity market vocabulary this year

13. Everyday challenge in today's markets already:
balancing the variable supply and demand
16. But grid expansion can sometimes be extremely
challenging – the German example
Montel News, 16 November 2016:
730km of the needed 7,900km has been built since 2009
17. Issues to solve: how to make the markets work
and fit for renewables

Guidelines

Energy transition
19. Increasing trade close to real-time creates
opportunities for balance service providers
Both generators and consumption are
active in the balancing and reserve power
markets in Finland
20. Criteria for balance service providers: does it
start, how fast does it ramp, how long does it last?
