Improvements in Energy Access for Health Facilities in Haiti

Remote hospitals rely on generators approximately 60% of the time due to the lack of adequate power supply in Haiti. Energy storage is one of several strategies explored by the Improving Health Facility Infrastructure (IHFI) project to assess and enhance energy supply to under-served health facilities. Thirty-three grid connected energy storage systems were designed and installed to provide backup power to health facilities, improving power quality for sensitive equipment and mitigating unreliable grid intermittence. The flooded lead acid batteries ranged from 38.4kWh to 96.1kWh, with a 48VDC nominal voltage, providing backup in some cases only to critical loads and in other cases to complete facilities. Four out of the 33 systems without access to the grid or very poor grid reliability were designed as solar-diesel hybrid systems with solar photovoltaic installations ranging from 2kW to 9kW.
