| Plans and Prospects | |
| Offshore areas | No exclusive zones for offshore wind energy. Licenses granted mainly at the east coast. |
| Planned offshore windpower | 570 MW, potential around 3 GW |
| timing | 2010 |
| Transmission System | |
| TSOs | ESB National Grid (will soon become EirGrid plc): 110 kV, 220 kV, 400 kV |
| Control zones and operators | EirGrid (entire country) |
| Synchronous Zone | Island of Ireland |
| Final electricity consumption (2002) [TWh] | 21,8 |
| Generation capacity (2002) [GW] | 5,4 |
| Peak load (2002) | 4,24 |
| Minimum load (2002) | 1,5 |
| Power Generation Portfolio [GW] | |
| Nuclear | 0,00 |
| Thermal (non-nuclear) | 4,76 |
| Hydro | 0,53 |
| Wind | 0,14 |
| others | 0,00 |
| Offshore Power Injection | |
| Suited Substations | East coast (220 kV substations):Finglas, Arklow, Great Island. 110 kV substations: many along the coast |
| Substation Voltage today | 110 kV, 220 kV; no reinforcement needed |
| Offshore power limit | 250 MW per 220 kV substation |
| Grid issues | |
| Grid code requirements | Power quality, power control, power curtailment, frequency control, voltage control (reactive power), voltage and frequency ride through. |
| Balancing | EirGrid, no penalties for unbalance; short-term predictions oblogatory for wind farms above 30 MW |
| Transmission bottlenecks | No bottlenecks identified. Reinforcements will be taken care of when necessary. |
| Necessary reinforcements | not specific to offshore wind power |
| Timing of reinforcements | Forecast statement until 2011 is just available. |
| External Factors | |
| Import/export/transit | Power exchange with Northern Ireland; HVDC interconnector Ireland-Wales is under discussion. Not related to offshore wind power. |
| other factors | Interconnector Ireland - Wales under discussion. |
| Trans Border Capacities | |
| Offshore Cable | |
| Connection, first projects | |
| Landing, first projects | |
| Best option, long term | |
| Connection and energy pricing | |
| Connection charges for DG | deep |
| Connection charges for offshore wind | |
| Priority access for renewables | |
| Minimum price | Via bidding system, price cap for offshore wind: 8.4 cents. |
