Such natural disasters can devastate existing electricity sources, as seen by the major disruptions in grid operations after Hurricanes Irma and Maria in Puerto Rico and Barbuda in the late summer and early fall of 2017. In Puerto Rico, Hurricane Irma destroyed 90 percent of the grid, leaving no means of communication between communities and centralized aid relief.1 While telecommunications companies were able to quickly establish emergency hotspots and repair cell phone towers, many communities did not have electricity to power their phones, and therefore were unable to access emergency communications and pertinent aid coming in from centralized locations.2 Furthermore, the primary method of backup generation in Puerto Rico consisted of fuel-based generators, which, along with diesel required to operate them, are largely imported.3 In the aftermath of Hurricanes Irma and Maria, however, the island experienced significant shortages in both generator and fuel supply, leaving residents with few or no options for backup electrification. While Irma and Maria wreaked havoc primarily in Puerto Rico and Barbuda, other Caribbean islands are similarly vulnerable to potential catastrophe brought on by future storms. As storms continue to increase in frequency and intensity due to climate change, and threaten grid operations of islands throughout the Caribbean, vulnerable countries like the Dominican Republic must have off-grid electricity generation available to provide critical services in the immediate aftermath of a disaster. Our objective was to assess potential methods of incorporating cost-effective, portable distributed solar power (referred to as pico solar) to meet these critical post-disaster needs by partnering with both the providers of solar products and the communities who could use them. PROJECT OBJECTIVE The project goal was to assess a means of preparing disaster-vulnerable communities in the Dominican Republic for energy challenges posed by future hurricanes. Pico solar products, particularly those produced by US-based company Goal Zero, have been used for disaster relief in the past in hurricanes Sandy and Harvey. It is important to note however, that rather than focusing our research and pilot program in Puerto Rico and other recently affected islands, we 1 Ferris, David. ”Puerto Rico’s Grid Recovery, By the Numbers.” Energy Wire, E&E News.

WHY THE DOMINICAN REPUBLIC? The Caribbean environment— namely its abundance of sun— led us to focus on pico solar products. The increased frequency and intensity of hurricanes, and the resulting solar variability increases after a storm, make solar generation a particularly good option. We began by connecting with Goal Zero, the company that had donated pico solar products to communities affected by hurricanes recovery efforts in the past. Through conversations with their staff, we assessed that the biggest challenges in the aftermath of natural disasters that caused power outages were the lack of lighting for rebuilding efforts and the inability to charge mobile phones for communication with family, friends, and local relief organizations. Specifically, Goal Zero mentioned that, in Puerto Rico, the island had no electricity backup plan in place in the case of a major grid outage. Goal Zero donated a large portion of its supply chain to Puerto Rico in the aftermath of the disaster, but noted that if communities had already had these products in place, they would have been able to connect and begin rebuilding more quickly. Furthermore, a donation model, they noted, is not sustainable due to supply chain constraints and lack of resources available in the long run. They stressed the need for electricity generation technologies to be included in pre-disaster mitigation plans. Therefore, rather than focusing on post-disaster grid rebuilding, we decided to address immediate post-disaster electricity needs such as communication and lighting and ways communities could better prepare in advance. We narrowed our scope to the Dominican Republic for several reasons. First, we had a personal connection to the country--one of our team members, Simone Kramer, is of Dominican descent and her grandmother lives in the coastal community of Boca Chica. This town is highly vulnerable to the effects of tropical storms and hurricanes, and her grandmother’s experiences offered anecdotal information about community energy access and disaster preparedness. Simone’s Dominican connections were also instrumental in helping us build out a network of contacts on the ground. Furthermore, the Dominican Republic is highly vulnerable to natural disasters. The country ranks 27th in the world in the United Nations’ World Risk Index, which indicates a country’s vulnerability to natural disasters.4 The country sustains substantial economic losses annually due to natural hazards (shown in table below). Therefore, there is an economic incentive to prepare. Given the risk and economic considerations, we felt there would be enough motive to garner interest from local stakeholders. 4 “World Risk Report 2016.” United Nations University Institute for Environment and Human Security. 2016. https://collections.unu.edu/eserv/UNU:5763/WorldRiskReport2016_small_meta.pdf. 2 Average Annual Loss (AAL) by hazard5 Hazard Absolute Capital [Million stock [%] US$] Earthquake 363.87 0.180 Wind 509.16 0.252 Storm 40.19 0.020 Surge Tsunami 0.24 0.000 Flood 100.83 0.050 Multi- 1,014.29 0.502 Hazard The Dominican Republic ranks among the top countries in the world in terms solar energy potential. One measure of solar potential is global horizontal irradiance( GHI). GHI measures the amount of radiation a horizontal surface on the ground receives from the sun. The higher the GHI, the more effective a photovoltaic solar installation will be at generating electricity. The average GHI in the Dominican Republic falls somewhere between 5 and 7 kWh/m2/day, with some regions approaching 8 kWh/m2/day6. Furthermore, GHI levels are consistent throughout the year, meaning solar photovoltaic installations can be used year-round. 5 “Dominican Republic: Disaster and Risk Profile.” Prevention Web. https://www.preventionweb.net/countries/dom/data/. 6 Solar GIS https://solargis.com/maps-and-gis-data/download/dominican-republic 3 We connected with local, regional, and multilateral stakeholders in a field research project that took place in Santo Domingo and Santiago (the two largest cities in the Dominican Republic) to raise awareness about portable solar technology opportunities and assess their utility in disaster preparedness. In each city, we brought together affected parties--including students, professors, business leaders, government employees, and engineers--to deliberate the means in which they could work to produce a resilient and proactive strategy for further incorporating and purchasing these products locally. Our pilot project followed a two-tiered approach, utilizing a partner university and their connections and resources as a base in both cities. The first tier entailed student trainings and community engagement and outreach, while the second tier comprised of convenings of stakeholders--students, professors, engineers, business leaders, and government officials--in both Santo Domingo and Santiago. 4 PARTNERSHIPS In order to centralize and streamline our project, we partnered with Pontificia Universidad Católica Madre y Maestra (PUCMM), a Catholic university with campuses in both Santo Domingo and Santiago, to enact this project. PUCMM was instrumental in helping us connect with key local constituencies and stakeholders in the electricity industry, the government, and disaster planning and preparedness. We hosted a technical training session with university students at each campus in an effort to both raise awareness of pico solar products and their potential use in disaster planning, while also learning from them about current practices in disaster planning in Dominican communities, and more generally about the state of electricity in the country. PUCMM in Santo Domingo also connected us with the rural community of San Antonio de Guerra about 40 minutes outside the city, where we had the opportunity to meet with leaders at the local school and community center, as well as community residents to discuss their thoughts on the incorporation of pico solar products into disaster planning and preparedness. The products used for the trainings and demonstrations were donated by Goal Zero, a U.S.-based pico solar producer, and we, in turn,
