What is Pumped Storage?
Pumped storage (or Pumped Hydro) is a way of storing electricity by turning electrical energy into stored (or potential) energy and back again. The system uses electricity to pump water from a lower reservoir to a higher reservoir. Pumping would normally happen during the night, making use of the cheaper electricity cost.
During the day, the water is allowed back through a hydro-turbine to generate electricity again to meet sudden spikes in consumer demand. This cycle of pumping and generating repeats on a daily basis, storing energy when there is substantially less demand on the national electricity grid and releasing it when demand is highest. By doing this, the Glyn Rhonwy Pumped Storage will help the UK achieve a low carbon economy, while bolstering UK energy security.
Who are we?
Snowdonia Pumped Hydro (SPH) was created by Quarry Battery Company (QBC) to develop the Glyn Rhonwy Pumped Storage scheme and provide stability throughout the construction and operation phases. SPH is the current developer and will remain so for the foreseeable future. QBC is the parent company of SPH.
At QBC we find disused quarry systems for conversion into pumped storage batteries. QBC is a small, green minded business that was created at the Centre for Alternative Technology, Machynlleth, Wales. QBC is funded by UK angel investors – individuals who wanted their money to be part of a low carbon future UK. Please see QBC's main site for more information.
