Introduction

Health professionals in rural clinics must address unexpected challenges on a daily basis. Poor infrastructure can delay the delivery of critical medical supplies, and inclement weather can make it difficult for patients to access the clinic. An unreliable energy source adds to these challenges. If the cold chain is inoperable when supplies arrive, vaccines, blood, and other medicines may go to waste. If a clinic is without lights, patients arriving at night must wait until morning to receive care. Selecting an appropriate source of reliable and sustainable energy as well as introducing measures for efficient energy consumption can help mitigate some of the challenges inherent in operating a health facility in the developing world. This article will provide an overview on options for the improvement of the energy situation in rural health facilities.
Most of the information related to electricity supply for health centers is based on the excellent USAID publication "Powering Health"[1].

Electricity Supply

Stepwise Approach to Electrifying a Health Center

  1. Identify the Health Center's Current Energy Demands
    Identify current energy needs and applications, e.g. for lighting, refrigeration, communication, etc.
  2. Account for Near-Term Change
    Determine whether energy demands will change in the near-term.
  3. Establish Target Energy Consumption in kWh/day
    Use tools such as the USAID Health Clinic Power System Design Tool (4 - Electric Load Inputs) or the Energy Audit Spreadsheet (Worksheet 7 - Future Electric Applications) to calculate the future electric energy consumption in kWh/day.
  4. Determine Technologies Needed to Meet Target
    Evaluate energy technologies.
  5. Procure, Design System, and Install Technology
    Select the most appropriate energy technology.
  6. Maintain and Financing Your Energy Technology
    Institute financing mechanism(s) accounting for operation and maintenance needs and costs.

Remember to contact an expert for assessment, system design, procurement, installation, and maintenance of energy technologies!

Defining Energy Needs

When considering the type of electrification needed to sustain daily operations, a facility must first understand its basic needs. The needs assessment will include an inventory of the types of equipment used in the facility and the power required to operate each device. Understanding the average “daily load”, or the amount of power required to operate equipment under normal working conditions, will influence the choice of power supply. Once the daily energy requirement is established, a range of electrification options can be considered. Understanding the need will also provide managers with a realistic budget for procuring, installing, and maintaining the new system.

Calculating Energy Needs of a Health Facility

The USAID Health Clinic Power System Design Tool (4 - Electric Load Inputs) and/or the Energy Audit Spreadsheet (Worksheet 7 - Future Electric Applications) as well as the examples of energy demands of typical rural health centers in developing countries can help identifying the overall energy demands of health facilities. The amount of expected energy consumption in kWh/day, in addition to expert consultation, will assisst in the selection of appropriate electrification technology.

Once a facility has comprehensively analyzed the energy requirements of its day-to-day operations, it must be determined whether those demands are likely to change. Facility managers must think strategically about the possibility that energy demands may increase due to the addition of patients, extended operating hours, or new services. Once this process has been completed and an adequate accounting of needs has been made, the manager can determine the various energy options to meet those demands. These options must be considered in light of all facility-specific variables.
