Itâ€™s among the most basic, most critical, and most overlooked resources needed to run a hospital: electricity. But in Haitiâ€™s Central Plateau, the flow of energy is intermittent at best. Consider that in Mirebalais, located 30 miles north of Port-au-Prince, the power goes out for an average of three hours each day. This poses an enormous challenge to running any hospital; surgeries are jeopardized, neonatal ventilators stall, the cold chain is interrupted, and countless everyday tasks get derailed. As Partners In Health co-founder Paul Farmer noted during a recent lecture at the Harvard School of Public Health, â€œItâ€™s not great if youâ€™re a surgeon and you have to think about getting the generator going.â€
To make sure the patients and staff at HÃ´pital Universitaire de Mirebalais (University Hospital) arenâ€™t left in the dark, PIH and its partners looked toward the sun. Stretched across the roof of the new 200,000-square-foot hospital is a vast and meticulously arranged array of 1,800 solar panels.
On a bright day, these panels are expected to produce more energy than the hospital will consume. Before the facility even opened its doorsâ€”the official opening is slated for Marchâ€”the system churned out 139 megawatt hours of electricity, enough to charge 22 million smartphones and offset 72 tons of coal. Perhaps most important is that the excess electricity will be fed back into Haitiâ€™s national grid, giving a much-needed boost to the countryâ€™s woefully inadequate energy infrastructure.
In a country ravaged by deforestation, the ecological benefits of this alternative energy source cannot be overstated: Annually, the system is expected to save 210 metric tons of carbon emissions. And while a sea of solar panels perched atop a hospital in the mountains of Haiti is certainly eye-catching, itâ€™s just one part of a comprehensive environmental strategy. Other green-friendly features at the hospital include natural ventilation that minimizes the need for air conditioning and motion-sensor activated lights that cut energy consumption by 60 percent when compared with traditional lighting.
This push toward sustainability and energy self-sufficiency translates into significant financial savings. In Haiti, electricity is expensive: The price per kilowatt hour is 35 cents, compared with 5.5 cents in New England. Using solar is expected to slash $379,000 from the hospitalâ€™s projected annual operating costs.
When fully operational, University Hospital is expected to be the largest solar-powered hospital in the world that produces more than 100 percent of its required energy during peak daylight hours, an impressive feat for the first-ever teaching hospital in central Haiti. The many lessons learned from the project will prove invaluable as PIH, its partners, and others undertake similarly ambitious and sustainable projects.
