Hydrometric Information

Measuring water levels and flow

We provide daily/hourly hydrometric information for each of the hydro schemes managed by ESB.

Our Role on the River Shannon

We have a statutory role to generate electricity at Ardnacrusha as outlined in the Shannon Electricity Act 1925, Electricity Supply Act 1927 and Electricity Supply (Amendment) Act 1934. In broad terms, this legislation permits ESB to generate electricity at Ardnacrusha and to manage the weirs, sluices and other works that are part of the Shannon Scheme.
