Changing lives with solar microgrids _ renew economy

Haiti is the poorest the country in the western hemisphere. Static electricity diagram Only 25 per cent of the 10.3 million people in the country have access to electricity. Gas finder One nonprofit organization is testing a solution that could not only change the lives of the unelectrified in Haiti, but could be a model of how to bring electricity to the 1.2 billion people in the world still living in the dark.

EarthSpark International has built a 93 kW solar-powered microgrid in the small town of Les Anglais (pop. Gas x tablets himalaya 3,000 in the “downtown” area), which currently supplies clean reliable power to approximately 2,000 people. Gas works park fireworks Why a Microgrid?

Haiti has more than 30 existing municipal microgrids, but most of them don’t work. Electricity generation by country And even when they do function, they run on diesel and operate just a few hours a day, a few days a week. E gaskell So EarthSpark’s goal was to provide people with 24-hour clean affordable electricity.

EarthSpark began working in Haiti providing people with small solar home systems and solar lanterns, products that are life-changing tools for people without access to grid electricity. Gas utility worker But the organization soon realized that those aren’t the solutions to which everyone aspires. Static electricity vocabulary words “To truly unlock economic opportunity, people need access to higher levels of electricity than what a solar home system can provide,” Allison Archambault, president of EarthSpark International, told RMI.

“With the right conditions minigrids can provide energy services in a low-cost sweet spot between small levels of energy consumption that can be effectively served by small stand-alone solar systems and traditional grid extension,” according to Eric Wanless, a principal in RMI’s international practice leading the Sustainable Energy for Economic Development initiative. Electricity history timeline EarthSpark isn’t the only group focusing on microgrids.

Husk Power has brought electricity to 200,000 people in the highly unelectrified state of Bihar in India, using rice husks to fuel microgrids; Powerhive, Devergy, and PowerGen are bringing power to East Africa with solar microgrids; and Gham Power is building solar microgrids in rural Nepal.

A microgrid can give residences and businesses enough power to run motors, process agricultural products, and power freezers. Npower gas price reduction Plus, much of the electricity used by rural industry is seasonal, such as an agricultural mill, which is used during harvest season and on market days.

“Building an energy system just for that mill would mean an asset that is under-utilized much of the time,” adds Archambault. Bp gas prices nj “But with a microgrid, you can use that capacity for other uses, and everyone buys down the cost for everyone else. Grade 6 electricity unit test We like to say our system is powerful enough to energize industry, and progressive enough to serve every single customer.” Tackling technical challenges

Many technical challenges arise when building a microgrid that you don’t necessarily encounter with individual systems. Kd 7 electricity socks The EarthSpark team looked all over the world to find a low-cost, high-functionality meter that would allow their small utility to customize tariffs, manage demand, and offer pay-as-you-use services. Electricity freedom system They couldn’t find anything, so they designed their own. Gas unlimited houston texas The SparkMeter technology is now installed in nine different countries serving microgrid and central grid operators.

The SparkMeter metering and billing system is a critical component in the Les Anglais microgrid as it allows people to prepay and buy as much electricity as they need, in the same way Haitians buy phone credits, and in the same way they are used to spending money on kerosene or diesel.

Tariffs are different for different customer classes, and there is also time-of-use pricing. K gas constant For example, in the middle of the day the solar array generates more power than is needed to charge the 400 kWh of batteries in the system, so the surplus electricity is sold at a cheaper rate. Gas monkey live Overcoming logistical challenges

Working in developing countries like Haiti brings a lot of logistical challenges as well. 93 gas near me There is often not a clear process for implementing innovative projects. Electricity vs gasoline When Earthspark hired a firm from the Dominican Republic to build the distribution system, the firm brought a crane to help install the poles and wires.

Unfortunately, the crane got stuck on the border for five weeks as the officials weren’t sure how to deal with a vehicle that was not a truck or a car. 3 main gas laws All of the linemen and staff, not to mention the community members, were extremely frustrated as the installation was put on hold for over a month. Electricity how it works Finally the head of the largest telecommunications company in Haiti lent the project a crane.

Archambault calls the process “derisking by doing.” The actual construction process revealed where the hiccups might be. K electric company “A lot of unknowns and a lot of risks remain,” she says. Bad gas 6 weeks pregnant “We’re doing the research and development on the business model, focusing on Haiti, but solutions we’re coming up with are relevant to a lot of places around the world that need energy access.”

One of the biggest challenges comes in the legal and regulatory framework in Haiti, or lack thereof. C gastronomie traiteur avis In the absence of a clear legal and regulatory framework it will be difficult to get investors. Electricity water analogy animation While family foundations, National Geographic, the United Nations, and USAID funded the first microgrid, Earthspark wants to get to an investable model, which means a proven track record.

All of these challenges are not specific to Haiti, as can be seen in R MI’s current work to help the Rwandan government raise the country’s electrification rate from 24 percent to 70 percent by 2018. Gas cap light RMI recently delivered a diagnostic with actionable recommendations to the government on how to supply around 50 percent of the population with power from the grid, and over 20 percent of the population with power from off-grid systems.

The diagnostic included a set of recommendations that need to be implemented quickly in order to create the conditions necessary for future success. Gas key staking tool The RMI team remains in Rwanda to help government and the private sector fit those recommendations into the nation’s evolving energy system.

“A big part of the work we’re doing in Rwanda and elsewhere in sub-Saharan Africa is all about helping investors and companies like EarthSpark clearly articulate the minigrid value proposition in the context of a host of electrification options to ensure that the capital that is put against the problem delivers the most impact,” says Wanless. 76 gas station jobs Promoting economic development

Residents of Les Anglais not only have access to reliable power 24 hours a day, but are also saving money on their energy expenses. Electricity song omd Before the microgrid, they were spending about $10 to $12 each month for kerosene and spending $3 to $4 each month to charge phones (at nearly $0.25 per charge). Gas leak los angeles Now residential microgrid customers are saving 80 percent of their household energy budget, paying about $2 to $3 per month for much better quality power. Gas prices in texas 2015 And EarthSpark’s larger business customers are saving 50 percent over what they were spending on diesel.

EarthSpark’s goal is to build 80 microgrids in the next five years, bringing power to over 200,000 people, a small dent in the 7 million Haitians still living without access to electricity. Gas natural fenosa But for those 200,000 people, it’s a game changer. M gasol “We have small enterprises using electricity for the first time, people starting new businesses. Gas hydrates are used The carpenter now has power tools.

The hotel and the mill have been able to drastically reduce their power bills, by switching off their big diesel generators. Gas prices going up to 5 dollars And people come up to me and tell me their children no longer have the smoke of kerosene burn their eyes when they’re studying,” says Archambault. Electricity lesson plans year 6 EarthSpark’s project in Haiti and RMI’s work in Sub-Saharan Africa are delivering clean reliable electricity to people and unlocking huge opportunities for rural communities around the world.
