Silvermines Hydro is a hydroelectric pumped storage power project located in Silvermines, County Tipperary, Ireland. It aims to turn a former mine site into one of Ireland’s leading clean energy facilities.
This pumped hydro power project can store as much as 296 Megawatts (MW), with a daily storage capacity up to 2,175MWh of electricity. This is enough to power 185,000 households or 21,000 small businesses in Ireland everyday. In addition, Silvermines Hydro will improve Ireland’s energy security, it will help keep the grid stable, while driving down electricity prices for customers.
Energy storage is necessary for future power systems because it keeps electricity reliable, balances usage, and supports renewable energy.
Silvermines Hydro is a key part of Ireland's move to a cleaner energy future. It will help Ireland and Europe meet their goals for reducing carbon emissions.

Siga Hydro held a Public Information Event to provide further project information ahead of the main design exhibition on Friday 27th and Saturday 28th February.
The exhibition boards from our recent public information event will be on display at Nenagh Library from 9th March to 15th March.
We encourage anyone who could not attend — or who would like to revisit the information — to drop in during the week to view the full set of boards.
