Rolling Blackout - Ireland

Ireland

On several occasions in the 1970s and 1980s, trade union strikes in Ireland's power utility, the Electricity Supply Board (ESB), led to rolling blackouts. However, rolling blackouts have not occurred for this reason since 1991. For such eventualities, the ESB have a zone rota system in place. The country is divided into regions which in turn are subdivided into zones, referred to by the letter codes A, B, C, X, Y, and Z. During periods when blackouts may occur, advertisements are placed in the national newspapers informing customers which region and zone they are in, and at what times of the day they have a high, moderate or low risk of supply interruption. (Customers fortunate enough to live close to a hospital may find they are on a "priority line" and do not lose power at all). The authorities appeal to the public to conserve electricity (especially during hours of peak demand); however, if and when electricity demand exceeds available supply, supply is cut in some or all of the "high risk" zones. If there is still a shortfall once all the high risk zones have had power cut, then the "moderate risk" zones start experiencing power cuts. The level of risk in each zone changes every three hours moving from "Low" to "Moderate" to "High" and back to "Low".

Famous quotes containing the word ireland:

    No people can more exactly interpret the inmost meaning of the present situation in Ireland than the American Negro. The scheme is simple. You knock a man down and then have him arrested for assault. You kill a man and then hang the corpse.
    —W.E.B. (William Edward Burghardt)

    In Ireland they try to make a cat cleanly by rubbing its nose in its own filth. Mr. Joyce has tried the same treatment on the human subject. I hope it may prove successful.
    George Bernard Shaw (1856–1950)

    Come, fix upon me that accusing eye.
    I thirst for accusation. All that was sung.
    All that was said in Ireland is a lie
    Breed out of the contagion of the throng,
    Saving the rhyme rats hear before they die.
    William Butler Yeats (1865–1939)
