Red John Pumped Storage Hydro Scheme

Why Pump Storage

Between 2007 and 2015, the total installed capacity of renewables electricity in Scotland has more than doubled.  Due to its intermittent nature, the rise in renewable generation has resulted in increased demand for flexible capacity to help meet energy balancing requirements for the national grid system.

Pumped storage hydro is considered by the Directors to be the most developed and largest capacity form of grid energy storage that currently exists.  This can help reduce renewable energy curtailment and therefore promote grid stability.

Community Ownership

The ILI Group will offer the local community an exciting opportunity to gain a stake in the Red John PSH project via community ownership. Local Energy Scotland, who are entirely independent from the ILI Group, can assist community members in various ways so as many as possible can get involved.

This includes support & advice through a network of local development officers, financial support via a range of loan and grant schemes plus access to their Infrastructure & Innovation Fund which provides grant funding for communities for innovative energy generation and storage solutions.
For more information please visit the Local Energy Scotland website

It should be noted that at present there is not yet a set value for community contribution for Pump Storage Hydro projects and we are currently awaiting Government advice on this.

We will update the relevant information when it is available to us.
