Effects of market coupling (2) – social welfare

Effects of market coupling (3) – consumer benefits

• Clear benefits for

consumers,

driven by overall

lower prices (up

to € 1.6 bill p.a. if

scaled up for EU

27)

• TSOs lose cable

income: price

convergence

• Nordic countries:

water values

increase – similar

effect as cables

Effects of market coupling (4) – non-quantifiable

Competition

• Capacity is optimized taking into account all bids and offers in all markets

participating in the market coupling, creating larger markets and more

competition – promoting price conversion across borders and regions.

Forward markets –

the need and the

ability to hedge

• Reduced need to hedge – larger markets absorb uncertainties/risks

• Improved ability to hedge – integration promotes more liquid forwards

Security of Supply

• More efficient utilization of the resources in the power system promotes security

of supply. This is becoming more important with the inclusion of more RES.

• Expected improvements in algorithm will further promote SoS

• More money to invest – improved ability (and reduced need) to hedge

• More efficient investments – better price signals / incentives

• Reduced need to invest – more efficient utilization of existing resources Investments

• Implicit auctions across regions promotes efficient optimization of a more

complex power system

• Efficient market coupling is thus key in promoting efficient inclusion of RES and

the in the transition towards a carbon neutral future

RES integration

Cable income Effects for consumers

Arbitrage via hourly price

differences

Flat prices in Norway, due

to hydro

Volatile prices Germany,

due to thermal capacities

and RES

Cables have price effect

Price decrease benefits

consumers, price increase

benefits producers

The sum of effects is

positive

Germany: likely lower

peak prices

Norway: In surplus

slightly higher prices,

in deficit lower prices

Grid and

interconnections

Is this enough, or do

we need capacity

markets?

Make sure capacity

mechanisms act

neutral w.r.t. other

measures and

incentives

• Capacity markets

should resolve a

form of market

failure

• Make sure capacity

markets do not

create new market

failures

Will a capacity market distort the effects of integration?

Reduce value by

“cutting the price

peaks”?

The energy transition need

interconnections and more

flexible demand/generation

…but capacity markets may

reduce their income,

including the income of

NordLink

Reduced

competition by

blocking market

access

• Flexibility is traded outside

the regular markets

• Limited (or no) access for

Norwegian generators

• Reduced incentives to

develop competitive flexible

sources in Norway and to

build interconnections to

Germany

• Costs to German

consumers

• Income to German

generators

• Lost opportunities to

Norwegian generators

Capacity mechanisms should not be local solutions

Not taking account of

X-border capacities

would increase cost of

solution

• Short-term: Higher

costs associated

with utilization of

existing resources

• Long-term: Higher

costs in addition

due to different

investments

Local solutions Cross-border solutions
