Ground Investigation 'GI' works got underway this week at our Earba Pumped Storage Hydro 'PSH' project.
A number of boreholes and trial pits are being undertaken, along with peat probing and geophysics.
The locations of these exploratory holes are shown on the map.
Although it is very early on in the process, before even the planning application has been made, these exploratory works enable us to better understand the ground conditions across the site. With a better knowledge of the soil and rock profiles, a 3D model of the underground conditions can be built. This means the main structures such as the dams and powerhouse can be positioned accurately, reducing the likelihood of changes once the planning process has commenced. Furthermore, the ground investigation data will mean that the construction methodology can be better described as there will be a better understanding of the different types of material that will be excavated
About the Earba PSH Project:
The Earba Project is a proposed pumped storage hydro ('PSH') scheme with an installed capacity of up to 1,800MW and stored energy of up to 40,000 MWh making it the largest such scheme in the UK.
Visit the project website www.earbastorage.co.uk to learn more about the project and why the UK needs significantly more energy storage.
