ESB has said it is inevitable that there will be homes and businesses without power tonight and into tomorrow as a result of Storm Brendan, which has brought gusts of over 130km/h to parts of the country.
There has been widespread power cuts, downed trees and localised flooding across the country as the storm passed over the country during the day.
The damage is mainly due to fallen trees on overhead lines because of the high winds.
A Status Orange wind warning remained in place until midnight for counties Donegal, Galway, Leitrim, Mayo and Sligo, with Met Éireann warning of a significant risk of coastal flooding.
While electricity has been restored in many western areas, more homes and businesses were hit as the storm moved east.
ESB says that 9,000 customers were without power, down from 30,000 at 6pm.
ESB's head of project delivery Derek Hynes had earlier said the majority of those affected were in the southeastern counties of Wicklow, Wexford and Waterford.
Speaking on RTÉ's Six One, he said a number of customers in the northwest also remain without power.
The main areas still affected by power outages are Enniscorthy, Arklow, Clonmel, Sligo and Leitrim.
Power outages peaked at 2pm this afternoon, when around 50,000 were without power, while over the last 12 hours power has been restored to around 100,000 homes and businesses as the storm tracked across the country.
A large number of overhead line crews have been deployed in the southeast since late afternoon. Crews are also being deployed now in the northwest, he added.
Salthill Promenade in Galway remains closed, after flooding during this evening's high tide.
City Council officials say the main section, from Blackrock to Seapoint, should reopen by tomorrow morning.
It is thought it will take a little longer for flooding to subside on the adjacent Seapoint Promenade and traffic will be diverted until later tomorrow.
Wind gusts picked up through the morning, with 135km/h recorded at Roche's Point in Cork. Wind speeds of over 100km/h were also recorded in Kerry and Mayo.
Irish Ferries cancelled its 8.45am and 8.45pm sailings between Rosslare and Pembroke, while the 2.45pm Pembroke to Rosslare ferry was been cancelled.
Stena Line cancelled a number of its services between Rosslare and Fishguard and passengers on all routes should check the Stena Line website for sailing updates. The maiden voyage of Stena's new ferry, the Estrid, was delayed for two hours today because of Storm Brendan.
The ship, described as among the most modern in the world, docked in Dublin today at 3.20pm on its first sailing from Holyhead.
Six Aer Lingus flights to and from Shannon were cancelled this morning. Flights to and from Edinburgh, Birmingham and London Heathrow were affected.
Two Ryanair flights, from Manchester and London Stansted, were diverted from Shannon to Cork.
Bus Éireann said that due to the ferry cancellations all its Expressway Eurolines 890 services were cancelled.

The Road Safety Authority urged pedestrians and cyclists to delay or cancel trips while the wind warnings are in place.
The Irish Coast Guard service advised people to stay away from exposed areas. A Status Red Marine Warning was in place earlier today but that has since been downgraded to a Status Orange gale warning.
Storm Brendan also affected ferry services to Donegal's offshore islands. There were no ferries running to Toraigh today due to the weather.
The Arranmore Red Ferry sailed to the island with a van-load of supplies at 8.30am and crew have been monitoring the situation since.
The other service to the island, the Arranmore Fast Ferry, did not run this morning and the situation is being monitored on an on-going basis.
Meanwhile because of the red marine alert, schools on Árainn Mhór did not open today. Many of the students attending the secondary school on the island travel by ferry from the mainland.

Advice for staying safe during storms
- Monitor Met Éireann forecasts for your area, as well as your local authority website
- Be aware of weather conditions and heed safety warnings
- Keep your Eircode to hand as it is helpful in times of emergency
- Very strong winds could make driving conditions hazardous, especially for cyclists, pedestrians, motorcyclists and high-sided vehicles
- Check vehicle tyres and turn lights on
- Do not drive through any flooded areas - be particularly vigilant near bridges and rivers
- If trees fall, electricity lines will come down. If a tree is down be careful as live wires could be there too
- Stay away from the edge of coastal areas, as well as cliffs, harbours, marinas, piers, rivers, lakes and breakwaters
- Power cuts are possible - charge phones and powerbanks, and check batteries in torches
- If power goes, use LED candles, not real ones
- Have your Meter Point Reference Number (MPRN) to hand when contacting ESB Networks. The MPRN starts with the digits 10 and is shown on the bill from your electricity supplier
- Check for any loose roof tiles and put away or tie down any loose items in gardens
- Clear loose debris from gutters and drains to avoid blockages. Trim any bushes or small trees that could cause damage
- Know where to switch off electricity, gas and water supplies
- Check on isolated or vulnerable neighbours and family members
