Norton Healthcare (system)

Norton Healthcare is a Louisville-based not-for-profit system operating 9 hospitals and 430+ locations across Kentucky and southern Indiana. Through a multi-year, multiphase energy partnership with Trane (covering ~2.8M sq ft across nine facilities) and a thermal energy storage 'ice plant' at Norton Audubon Hospital, Norton has cut peak electric demand, achieved ENERGY STAR certification at Audubon, and saved nearly $4M in energy costs since 2016.

Goals & progress

Reduce peak electric demand via thermal energy storage at Norton Audubon
Target Shift cooling load off-peak; sustain ~$4M cumulative energy savings trajectory by 2030 · baseline 2016 · 27-tank ice plant freezes ~74,000 gallons of water into ~52 tons of ice nightly; electric chillers shut off 2–6 p.m. and the facility runs on stored ice, cutting peak demand and emissions.
