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 organisation an exciting opportunity to make an investment in the Red John PSH project.

Local Energy Scotland deliver the Scottish Government’s Community and Renewable Energy Scheme (CARES) and are available to support the community organisation(s). This includes support & advice through a network of local development officers, resources and access to funding. For more information please visit the Local Energy Scotland website

Community Benefit
Scottish Ministers do not have powers to mandate developers to provide community benefits from renewable energy schemes.  However in partnership with industry and communities have  developed national guidance through their Good Practice Principles, which they encourage all developers to use. Pumped Hydro Storage is not classed as “renewable” and as such it is for developers to consider the appropriateness of community benefits however the Scottish Government would encourage them to do so.
