Reference excerpt

In Guyana, the areas outside of the coastal plain are referred to as hinterland. Approximately twenty percent of the Guyanese population live in the hinterland. The population mostly consists of Amerindian communities who have little access to modern energy services such as electricity, light and modern fuels for cooking and transportation. This situation contrasts with the coastal plain, where there is access to the electricity grid. Several initiatives are in place to improve energy services in the hinterland. According to a 2013 survey of Amerindian villages done by the Inter-American Development Bank, "the most common source of electricity was a government-donated 65kW photovoltaic panel, and the second most common was a village-operated diesel generator. A few households reported having personal generators and privately purchased photovoltaic panels. In most villages, electric service is intermittent, provided for only four to six hours per day." St. Ignatius is an exception, as the community receives electricity from the Lethem grid.

Photovoltaic installations Photovoltaic systems can be Solar Home Systems, installations for a specific application (like a water pump or freezer) or community or mini-grids serving multiple users. No public records exist on private solar home systems in use in Guyana. However, several development projects have comprising solar home system (SHS) installations or portable systems (Pico-PV) for small lights etc. have been carried out in Hinterland villages. These projects typically use a one size fits all approach to serve a large number of beneficiaries. Solar systems for community use or specific consumers are generally larger in size, and designed specifically to meet the electric load.

Biofuels

The Institute of Applied Science and Technology has been investigating rice husk for combustion, and vegetable oils (palm, coconut, jathropa, wastes) for biodiesel production, with large scale palm oil based production facilities in Wauna, Region 1. Development of a national Agro-Energy Policy has been reported, but information has not been updated since 2008.

Biogas The GEA reports small scale biogas production at 5 sites in Georgetown, Linden and Berbice, using mostly low-cost polyethylene-film tube digesters of plug-flow digesters. Many have been supported by IDB and the Institute of Private Enterprise Development. Pay-back periods of 3-7 months have been reported. A similar digester has been built in Bina Hill, but this digester is currently not operational.

Projects and initiatives

2004-2010 Unserved Areas Electrification Programme The Government of Guyana implemented this programme with loan support from the Inter-American Development Bank (IDB) in 2004, to make improvements for Guyana Power and Light, and a hinterland energy component, using Solar Home Systems and community-based systems for schools to provide community and household access to electricity. The systems in Yarakita, Capoey, Kurukubaru and Muritaro comprised a 125 W monocrystalline panel and flooded lead acid battery. The schools in these villages received 250 W system with inverter, 8x25W bulbs and 120 V outlets. Another 12 villages received a total of 1200 SHS with 65 W panels and maintenance-free AGM battery, and one 260 W system for the school. Wind speed measurements were carried out in Orealla, Jawalla, Campbelletown and Yupukari, but wind power potential was found to be insufficient

2009 Rural Electrification Project This project was funded by CIDA, implemented jointly by the Latin American Energy Organisation (OLADE) and the University of Calgary School of Business. The Guyana Energy Agency was the national supporting agency. In the village of Wowetta the following were installed; 49 Solar Home Systems (40W MC Kyocera panel, 92Ah Deka AGM battery, 8 Amp Steca controller, one 7W and one 15W CFL 12V lightbulb), a freezer for the village shop (SunDanzer 24V freezer, 2x130W Kyocera panels, a 15 Amp Steca controller and two 12V lightbulbs), a Lorenz submersible water pump for irrigation of vegetable garden (four 85W panels, Lorenz 200 pump controller), an electric 110 V cassava mill powered by a diesel generator, and a joinery shop. A field visit in May 2011 showed that the SHS and solar freezer were working well, but the water pump was defective. In addition, due to several overcast days the freezer was temporarily emptied due to insufficient cooling.

2006-2008 Hinterland Electrification by Renewable Energy Pilot Project The United Nations Development Programme and Office of Prime Minister installed 3 PV systems for income generation, one in Wauna to support a peanut processing business, one in Kato for a vaccine freezer and battery charging service and one in Orealla to support Fruit Cheese production. Also, efficient woodstoves were introduced in Orealla and Kato to reduce firewood consumption and respiratory illnesses from smoke inhalation. Wind measurement was carried out in Paramakatoi, but proved insufficient for wind power generation In Kato an opportunity was identified to use small hydro-power at the Chiung River to operate a water pump for irrigation purposes, and a prefeasibility study was carried out. In 2011 the hydro-power option is pursued by OPM and under EU support to provide the school in Kato with electricity and irrigation for the nearby fields.The UNDP further expanded on this in 2011-2012 and 2013–2015 by a needs assessment survey carried out in Regions 1 and 7 to identify specific energy needs and potential energy sources.

Solar home light kits

In 2009 the Guyana Energy Agency and Office of Prime Minister in collaboration with Ministry of Amerindian Affairs provided 1000 portable solar light kits to 19 Villages in Regions 1,2,7,8 and 9. The kit consists of a 15W panel, a charge control cabinet containing a 20Ah battery and three 11W CFL light bulbs. In 2011 another 100 solar light kits were procured, with new design and LED light bulbs.

Worked examples

Example 1 — a first encounter with Hinterland energy in Guyana

Start with the simplest possible case. Write down what Hinterland energy in Guyana claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hinterland energy in Guyana before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hinterland energy in Guyana ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hinterland energy in Guyana

In research: Hinterland energy in Guyana appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hinterland energy in Guyana in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hinterland energy in Guyana is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy in Guyana, so understanding it makes those chapters shorter.
In everyday life: Look for Hinterland energy in Guyana outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
