SSE has filed to build a 1500MW pumped-storage hydro project near Fort Augustus in the Scottish Highlands.
The utility developer submitted a Section 36 application that would upgrade an existing consent at Coire Glas from 600MW, providing a storage capacity of 30GWh.
The bigger scheme will require a larger underground powerhouse and other related infrastructure but the overall size of the reservoirs unchanged.
SSE has previously called on the UK government to introduce specific supports for pumped-storage hydro projects.
Coire Glas was originally consented by Scottish ministers in 2013.
