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.

Intelligent Land Investments (ILI) (Highlands PSH) Ltd

Notice is hereby given that Intelligent Land Investments (ILI) (Highlands PSH) Ltd has been granted consent under section 36 of the Electricity Act 1989 by the Scottish Ministers to construct and operate the Red John Pumped Storage Hydro Scheme, a pumped storage hydro facility with a storage capacity of approximately 2800 megawatts hours and approximately 450 megawatts of installed electricity generation capacity. It is located approximately 14 kilometres south west of Inverness within the Highland Council planning authority area.

The Scottish Ministers have also directed, under Section 57(2) of the Town & Country Planning Act (Scotland) 1997, that planning permission is deemed to be granted for the development.

A copy of the decision documentation and this Notice has been provided to the Highland Council to be made available for public inspection by being placed on the Council’s planning register.

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.
