Offshore Wind in Gate 3

• Total Renewables in Gate 3 is approx 4000MW

• 3 Offshore Projects total almost 800MW (20% of Gate 3)

• Individual Projects

– Kish Banks off Wicklow coast for over 360MW

How to connect Offshore ?

Offshore study objectives

• Find the optimum connection strategy which:

– Optimises overall system costs

– Maintains System Reliability

– Permits Offshore Power Delivery

• Utilise that strategy to inform the TSO offshore

functional designs and policies

Conclusions thus far• Meshed network is optimum not radial - Better utilisation of circuits/Higher reliability

• Network can be developed incrementally

• Offshore/Onshore network are symbiotic

• Reinforcements required onshore are same as many already being proposed

• Interconnectors will optimally develop from offshore generators to other networks as well as from

onshore points - Power flows bi-directional in models

• Smart grid devices can enhance network flexibility and assist in minimising scale of offshore network

• Mixed AC and DC cable network most likely at present (need further work in this area)

• Market forces (outside the scope of this work) or economic reasons may drive use of DC technology

• Voltage level at least 220kV

• Offshore transmission stations should be designed with the potential for future expansion

Overview

• Gate 3 Connections

• GRID25

• East – West Interconnector

• Off-Shore Grid Study

• ENTSO-E

Multi-model approach for ENTSO-E

North Sea Region

• 10 countries: • Ireland, United Kingdom, France, Belgium,

Luxembourg, Netherlands, Denmark, Germany,

Norway and Sweden

• Four countries volunteered to do the

market modelling: • Belgium, France, Netherlands and Ireland

• Results will inform next ENTSOE Ten-

Year Network Development Plan

(TYNDP)

Ten Year Network Development Plan

24

ENTSO-E Ten-Year Network Development Plan (TYNDP)

The TYNDP presents a forward-looking proposal for electricity transmission infrastructure

investments across 34 European countries.

The objectives of the TYNDP are to ensure transparency regarding the electricity

transmission network and to support decision-making processes at regional and European

level. It points to significant investments in the European power grid in order to help achieve

the European energy policy goals:

• Increasing the use of renewable energy sources (RES) to 20% of total energy

production by 2020;

• Further promoting the Internal Energy Market (IEM) by alleviating congestion on the

transmission network;

• Ensuring security of supply (SoS) and system reliability of an increasingly complex

transmission system across the ENTSO-E area.
