Maintenance Logs and Checklists

Maintenance logs and task checklists should be maintained for all on-site energy supply equipment.

Load Analysis and Example Calculations

A fundamental part of energy management, and the first step in improving a health facility energy system, is an electrical load inventory.  An electrical load inventory is a listing of all electricity-consuming equipment in a facility, everything from light bulbs to expensive lab equipment to cell phone chargers.

The quality of grid power in Haiti is ranks among the worst in the world. Many health facilities receive only a few hours of power per day, with prolonged outages of up to a month not uncommon in some locations. The lack of reliable electricity in health facilities across the country complicates the storage of cold chain dependent blood, laboratory reagents and HIV rapid test kits. Power anomalies cause damage to laboratory equipment and jeopardize the accuracy of sensitive laboratory tests. In addition, a significant portion of many health facilities operating budget was used for the purchase of diesel fuel to power generators during frequent power outages. Reducing this expense would allow these facilities to use these funds for other priority needs.

A hypothetical clinic in the Kalahari Desert of Botswana currently has a small refrigerator, lights, hematology mixer, microscope, computer, and communications equipment. It is determined that the average daily load of the clinic is 13 kWh per day with additional load of 2 kWh per day expected in the near future. The clinic is not connected to the grid and currently utilizes a diesel generator to partially meet its energy needs. An international donor agency has been working with this clinic to improve local health care service delivery and would like to explore different options for upgrading its power generation systems.
