There's a warning Ireland is under prepared if faced with a global energy crisis.
A former managing director of the ESB, says Ireland is the least prepared in Europe when it comes to energy security.
The EU could face challenges with energy supplies this winter, as it tries to reduce dependency on oil and gas imports from Russia.
Ireland's energy regulator - the CRU - is considering setting high tariffs on large consumers and data centres.
Former head of the ESB, Don Moore, says Germany has 100 days of gas storage which it builds up during the summer months to off-set higher demand in wintertime.
Mr Moore, who's the Chair of the Energy and Climate Action Committee at the Irish Academy of Engineers, says Austria has a year's worth of gas storage, while Ireland has gas reserves.
