On a recent trip to Palestine, I had the opportunity to meet with a long-time HOMER Energy customer, Comet-ME, an Israeli-Palestinian NGO bringing off-grid solar power to villages in “Area C” of the Occupied West Bank. The organization’s Elad Orian and Tamar Cohen took me on a tour of a new project in the village of Jeeb al-Dheeb. The project was funded by the Dutch Foreign Ministry, which gave about half a million shekels ($140,000) for materials and supplies.
Women run day-to-day life in the village of Jeeb al-Dheeb, a cluster of stone buildings housing 40 families. During daylight hours, few men are in sight: They leave in the early morning hours to cross the pedestrian-only Checkpoint 300 to Jerusalem (a mere 20-minute drive from the village), on the other side of which they wait for day labor opportunities with Israeli contractors. They come back well after dark. Because of this reality, in this village it is the women’s committee that took on this electrification project in partnership with Comet-ME.
Unlike energy poverty in the developing world, geography plays no part in Jeeb al-Dheeb’s situation, which is created wholly by politics. The reality for Palestinians living in areas designated “Area C” is a lack of infrastructure and basic services accorded nearby Israeli settlements. Providing power to Palestinians living in “Area C” is Comet-ME’s mission. Most of the NGO’s projects are in rural villages spreading out over a larger geographical area than Jeeb al-Dheeb, with inhabitants often living in tents or in caves. Jeeb al-Dheeb has a semi-urban fabric and a somewhat different set of energy needs. Despite this, Comet-ME realized — after the organization’s first meeting with the women’s committee — that this partnership could be a perfect formula for a successful solar microgrid project.
Rural electrification ‘revolutionary’ for women
The committee was highly motivated to have this project come together. Although everyone benefits from electricity — which brings a connection to the outside world through television, phones, and computers — electrification is revolutionary for village women, because refrigeration, washing machines, and other cooking and cleaning appliances literally save them from hours of work each day.
The committee’s main objectives (in particular electrification) are far from selfish, however.
“They want their village to be self-sufficient and not reliant on nearby towns for basic needs,” explains Cohen, Comet-ME’s organizational development manager. “They also hope to bring people back to the village, where lack of power has been driving young people to other locations. Their third goal is to instill in their children a sense of pride in their community.”
As we arrived for our tour, women’s committee members began to come out of their homes to greet us. The first brought out a tray of tea with fresh mint leaves and cookies. The second woman began walking toward us with another tray of tea, and when she saw that we already had some, returned with a tray of tiny cups brimming with cardamom-spiced Arabic coffee. At each home we visited, women brought us a gift of food or beverage, exemplifying the incredible generosity and welcoming culture of Palestine.
After funding for the project was secured, it took about eight months to get from planning (using HOMER Pro) to implementation. Supplies were trucked in, a challenge with the steep, winding roads. In fact, the batteries (weighing approximately 500 lbs each) were delivered in a truck that just couldn’t make the climb. Two trucks were dispatched to the bottom of the hill, where villagers and volunteers transferred the cargo by hand — and once in the village, into the custom-built electricity building.
Microgrid brings village 24/7 power
The solar array (30 kWp) is located on leased land next to the village mosque and kindergarten. Directly beside it is the electricity building. One room holds the battery bank, which consists of 2 strings of BAE solar gel batteries 3000AH at 48V (a total of 288 kWh). Next door, three SMA 8 kW Sunny Islands inverters bring power to the batteries and homes from the SMA Sunny TriPower 25 inverter.
The women’s committee was eager to show us how power has changed their lives. First, they took us to the community room, where once a week Red Crescent provides a health clinic. I started to take photos, and the women urgently pointed to the corner. I was confused, then realized they wanted me to photograph the few simple medical instruments they could now use for the first time.
Before this project brought 24/7 power to Jeeb al-Dheeb, the village only had 3 hours per day of diesel-generated power. Not only was the diesel fuel expensive, its fumes were noxious to residents. As part of this project, the diesel generator was refurbished and serves as the system backup. Currently, it runs for 10 minutes a week for maintenance only, so the system is capable of operating on 100% solar. However, depending on power demands, the diesel generator can also be used as an energy source in the future.
HOMER models bring specifications into focus
Power demands and use constituted a large part of the project’s planning process. This village and situation were different than the ones Comet-ME has been doing up to this point, and because there was no detailed consumption data for this situation and thus the system was based on many unknowns, the organization took a two-pronged approach to its success. First, Comet-ME worked closely with the women’s committee to ensure it understood the community’s needs as well as to set realistic expectations for the project. Second, it relied on HOMER Pro, which Comet-ME uses to model all its installations, to ensure the system would be efficient, sustainable, and properly sized.
As we walked to the next building, the women explained that one of their most exciting new appliances was a milk churn for making Palestinian Labne, a type of drinkable yogurt popular in Palestinian cuisine. Before the microgrid, making Labne was an hours-long, labor-intensive process of mixing and shaking by hand. The women expressed so much joy that I pictured an industrial-sized machine “churning out” Labne. We went up a set of stairs to an immaculate and otherwise empty porch, in the middle of which stood a small residential-size machine. Its owner, an elderly village man, displayed it proudly for a photo as well. Afterward, we were treated to the yogurt drink along with fresh-baked pita.
Comet-ME’s approach to system sustainability differs from those of many microgrids in developing countries, where systems are set up, villagers receive a few days of training, and the organization leaves everything in those people’s hands. Comet-ME, because it’s not dealing with great distances (Israel/Palestine is the size of Rhode Island), can provide its own highly-trained microgrid experts to perform maintenance and repairs. This way, projects aren’t left completely to communities that lack the ability to fully manage a microgrid. Day-to-day management remains with the women’s committee.
Comet-ME’s fee strategy: ‘This is not a gift, it’s a service’
“The (pre-paid) fees rationalize electricity use,” explains Orian, Comet-ME’s co-founder, and general manager. “The money collected covers costs of the backup diesel generator as well as the leased land housing the solar array.” Households are rationed to 2.5kWh per day. If they reach their daily limit, the power is cut off and resumes the following morning, ensuring enough power for all and putting responsibility for the microgrid in the villagers’ hands. Residents may use electricity for all household needs except heating and air conditioning. Because the project electrified the entire village at once, Comet-ME was able to purchase in bulk identical, energy-efficient refrigerators for residents’ homes.
Our final stop was a storage room holding what may be the village’s most treasured new appliance. The women explained that before electrification, there was no ice cream in Jeeb al Dheeb. Carried from the nearby village, it would have melted before it could be eaten. As we walked to the storage room, I recalled my experience the night before. I was at this time staying with my Israeli cousin in Jerusalem. Saturday evening, my cousin’s daughters had a craving for ice cream, so we drove to a gas station, bought some Ben & Jerry’s, and brought it back to their home to eat. I thought of that experience as I watched a small boy carefully consider the three choices in the “ice cream freezer” (the type used as meat freezers in many American homes). One of the women helped him reach the item he wanted, and he went out into the sunshine to sit on the stone steps and enjoy his treat.
