Progress and Peril in Puerto Rico

Five months since Puerto Rico was devastated by Hurricane Maria back in September, over half a million people remain without power, and the remainder face unreliable electricity. Solar energy provides opportunities for relief, recovery, and resilience. The Solar Gardens Institute is working in each of these areas with short, medium, and long-term efforts.

Please donate to help us provide immediate relief, medium-term recovery, and long-term resilience in the face of future climate disasters.
In remote mountain communities, nearly every power pole was damaged.


SGI is delivering solar-powered relief to the remote community of Ciales, which was impacted by the eyewall of the hurricane and experienced high winds, flooding, and loss of power. The most acute needs are people dependent on medical devices. We work with local partners such as the Catholic parish, who can identify the individuals most at risk who can benefit from battery powered devices powered by solar energy.

Children with asthma are at risk of hospitalization (or worse) without their medications, which are typically delivered through a nebulizer. Without power, plug-in devices can't be used, so we have provided battery powered nebulizers along with battery chargers and small solar panels.

along with other health problems.
Now, solar energy charges the batteries
for his nebulizer, providing life-saving medicine.
The elderly are particularly vulnerable to the loss of power, at risk of falls in the darkness as well as depression. SGI provides lanterns that can be charged by solar energy, USB, wall outlet, car cigarette lighter, or hand crank. Solar powered fans can provide cooling for bedridden patients, who are susceptible to bedsores in the heat.

Workers for the parish located 78 year old Don Diego living in a remote area of the mountains. His home had been severely damaged, and he had been unable to access FEMA aid because he had no government ID. Aid workers were able to get him an ID and at least clean up some of the debris around his house, while SGI provided a solar lantern for light at night.

In the medium term, households, businesses, aid distribution warehouses and community centers are working to install off-grid solar energy with battery storage. These systems can provide charging, communications, and refrigeration for medication. Even a single small installation can benefit dozens of residents without power.

Unfortunately, even if the money is available and the panels are paid for, bottlenecks in the port and skilled labor shortages can cause waits of a month or more for systems to be installed. In the meantime, residents must use generators, which have a high fuel cost and can break down. However, the promise of reliable power is worth the wait!

The Puerto Rico Energy Commission has released preliminary rules for microgrids. A solar powered microgrid including its own batteries could connect to the larger grid, but disconnect and remain operational during power outages. The rules allow the microgrids to be owned by cooperatives - local community ownership!

SGI has hired two interns at the University of Puerto Rico to help plan a Solar Gardener Training. Our goal is to train 50 solar gardeners who will each begin the work to with local governments and organizations to develop shared microgrids in their communities. Puerto Rico can become a model for the rest of the world with an electricity system that is renewable, resilient, and community owned.

Proposed Rules for Puerto Rico Microgrids | Greentech Media


Puerto Rico will be home to the first solar gardens implemented as microgrids!

According to the commission's regulation, “a microgrid shall consist, at a minimum, of generation assets, loads and distribution infrastructure. Microgrids shall include sufficient generation, storage assets and advanced distribution technologies to serve load under normal operating and usage conditions.”

All microgrids must be renewable (with at least 75 percent of power from clean energy), combined heat and power (CHP) or hybrid CHP-and-renewable systems. 

The regulation applies to microgrids controlled and owned by individuals, customer cooperatives, nonprofit and for-profit companies, and cities, but not those owned by the Puerto Rico Electric Power Authority (PREPA). Owners must submit a registration application for approval, including a certification of inspection from a licensed electric engineer, and an annual fuel, generation and sales report that details generation and fuel source, as well as any change in the number of customers served.

Tallahassee Energizes Inaugural Community Solar Project | Solar Industry

The Florida state capital might’ve made national headlines after seeing its first snowfall in decades on Wednesday, but the City of Tallahassee also recently marked a major renewable energy milestone: the completion of its first community solar farm.

According to a city press release, crews finished construction on the 20 MW, 120-acre solar farm last month. Located on property of the Tallahassee International Airport (TLH), the project was a partnership with Origis Energy USA and included the installation of more than 200,000 thin-film solar panels. Earlier this week, solar energy generated by the farm became fully integrated into the city’s electric grid.
