Why Pumped Storage

Recent high energy prices have highlighted how much Ireland relies on imported fuels for electricity generation.  This dependence can be reduced by generating electricity locally using renewable energy sources. However, renewables produce variable amounts of electricity, sometimes resulting in excess power that goes to waste, and other times producing too little.

Pumped Hydro addresses these issues by capturing excess renewable energy and releasing it when renewable generation is low or demand is high, ensuring a greater share of locally generated electricity for consumers and reducing the need for fossil fuel power stations.

Proven and reliable

Pumped storage is a proven, reliable, and environmentally friendly technology with significant advantages over other energy storage systems. It produces energy without the need for chemicals or scarce minerals and operates with zero emissions and reducing the need for fossil fuel use. Additionally, pumped storage plants have long lifespans, often beyond fifty years.

Project Benefits

When built, Silvermines Hydro will bring many benefits to Tipperary, Ireland, and the EU.

It will:

  • Help keep power reliable by storing and balancing renewable energy to ensure a steady supply of electricity

  • Cut costs by storing cheap energy when it is available and use it during peak times to lower bills

  • Help the environment by using more renewable energy, reduce waste, and cut pollution

  • Make better use of renewable energy instead of relying on imported fuels

  • Create jobs, boost local economies, improve community amenities and create new opportunities

Helping diversify energy sources

Silvermines Hydro is part of the development of an integrated energy market for Europe. This fully integrated market will enable the EU to:

  • Ensure affordable, secure, and sustainable energy for all citizens

  • Advance the use of renewable energy for a low-carbon future

  • Enhance market efficiency and benefit consumers both within Ireland and Europe

For a low carbon future
