WP15 Economic impacts of the

demonstrations, barriers towards scaling up

and solutions

2

Objectives

The main goals of WP15 were to assess the economic (TF1 & TF3) and

technical (TF2) impact of each demo tested in the Twenties project, in

order to identify barriers and to propose regulatory recommendations

to overcome those barriers.

In the majority of the buses the wind penetration will not be limited

because of voltage reasons.

In these cases the wind penetration will be limited because of

transmission capacity constraints.

In the event that the wind power is limited because of voltage reason

the voltage control allows avoid this limitation

TF2


Results suggest that new offshore network capacity to allow increased

exchange of power between different countries will be important for

realising the full potential of new wind power developments.

Local surpluses of wind power to be used elsewhere but it also

facilitates reserve power to be held remote from a particular area.

However, it might also allow cheap generation with high carbon

emissions in remote areas to be used instead of lower carbon fossil

fuelled plant in a local area.

In addition, as offshore wind power is concentrated in relatively small

geographical areas, critical weather conditions can lead to large

variations in offshore wind power production.

The New Storm Control can help to diminish reserve requirements,

reducing the maximum reserve to approximately 50% of the one

corresponding to the old control case.

TF 3 Main findings

Scaling-up of Demo 5 NETFLEX (Elia) in CWE

PFC and DLR bring benefits for the system with lower implementation costs and

time than conventional assets

• Smart-controller of PFC in Belgium borders could reduce system costs by

50 M€ (250 M€ if fully deployed in CWE)

• Broad DLR deployment in CWE would reduce system operational costs in

125 M€

Main source of regulatory barriers for each TF

TF 1: market arrangements

Do not favor the participation of RES and (at least small) consumers in

electricity markets

TF 2: network and market arrangements

National frameworks for transmission planning, financing & operation

Offshore generation: support schemes, priority access, curtailment, etc.

Market designs: CACM, balancing

TF 3: network arrangements

National frameworks for infrastructure planning, financing & operation


17

Recommendations & some initiatives


• Day-ahead markets for minimum services

• Flexible market adapted to RES & loads TF 1

• Common framework for offshore generation

• Role of offshore generation

• Harmonize market designs

• Framework for balancing sharing

TF 2

• Definition of roles & responsibilities

• Coordination for planning infrastructure

• Harmonization of network codes for grid operation

• Development of joint support mechanisms for grid financing
