In 2016, the Massachusetts Department of Energy Resources contracted with Arup to conduct an Energy Resilience Assessment of 12 state-owned care facilities which house difficult-to-relocate residents who live on-site 24/7. For all sites, an extended loss of utility service could render the facility non-operational and require costly and potentially risky relocations of patients or clients. The goal of the study was to identify clean energy technologies to improve on-site energy resilience and increase the duration or effectiveness of on-site power sources, with the overall goal of avoiding relocating residents. This session will provide an overview of the study and explore fiscal and environmental considerations and lessons learned.
