Plans have been revealed to install a biomass “energy centre” at an Inverness secondary school.
Highland Council has applied for permission to install the new system at Inverness High School.
The project will precede upgrades to classrooms at the front of the school.
A council spokeswoman said biomass fuel would be sourced locally and would help create “significant carbon savings” in line with Scottish Government policy.
She added: “The main heat source of the energy centre will be from a modular biomass system fed by wood pellets and gas boilers to boost output during periods of peak demand.
“The energy centre will also house the electrical switchgear for the buildings along with control equipment that will drive the new services installations in an efficient manner.
“There may also be a pass through learning provision accommodated in the unit that can be used for curriculum energy activity.
“Timescale for delivery will be approximately 12 weeks from the issue of planning and building standards approvals.
“This project will precede the upgrading of the classrooms in the front wing.
“Works to the classrooms will include new windows, wiring, IT and heating provision.”
