Geisinger Health Systems, one of the largest healthcare networks in Pennsylvania, turned to A1 Energy in order to install LED lighting retrofits in several of its facilities. With the help of Act 129, the payback periods of the projects were shortened and Geisinger was able to leverage the savings for additional energy projects later. Overall there were 2,150 lamps replaced, close to $16 thousand in rebates and incentives, and approximately 316kWH of energy savings with the projects.
