BACKGROUND
Characteristics of the
Hinterland
Covers about 85% of the country’s territory, with 20% of the population. Occupied mainly by our indigenous peoples in about 200 communities. Residents exist mainly by subsistence farming, fishing and hunting. Prior to 2007, access to electricity was very low.
UNSERVED AREAS ELECTRIFICATION PROGRAMME
(UAEP)
- Hinterland Component
Objective 1
• Determine the options and technical, economic-financial, institutional-administrative, socio-environment requirements for viable hinterland electrification schemes.
Objective 2
• Implement a number of pilot projects to determine their viability for possible replication.
HINTERLAND STUDY
26 Communities were studied, chosen from
all 10 Regions
Energy use and needs in the communities
were studied
Options for wind, hydro, biomass and
solar power were considered
“TO DETERMINE THE OPTIONS & REQUIREMENTS FOR HINTERLAND ELECTRIFICATION”
HINTERLAND STUDY FINDINGS
Key Findings
Energy consumption was primarily for cooking and lighting. 85% of households used Kerosene “flambeau” lamps and wood for lighting Ave. monthly expenditure on kerosene for lighting – GYD$1,645
Priorities for electricity: 1. Lighting 2. Entertainment
and information – (power for radios, CD players)
3. Refrigeration of food
4. Power machinery for productive activities
Households were willing to pay GYD$1,000 per month for electricity service
HINTERLAND STUDY - RECOMMENDATIONS
CLASSIFICATION THE VILLAGES
GROUP 1
Existing mini-grid Rural
Infrastructure Significant local
government institutions
Some commercial / productive activities
GROUP 2
Small number of local government institutions
Potential for commercial / development activities
Small number of local government institutions
Less than 1,000 residents
Primarily subsistence economies
GROUP 3
- Majority of communities were classified as Group 3
HINTERLAND ELECTRIFICATION PROCESS
CHALLENGES
1. Low purchasing power of residents 2. Low demand for electricity 3. Limited economic activities in some
areas. 4. Houses are largely dispersed : > 500 m
apart in some cases 5. High transportation cost from coastal
areas. 6. Limited technical skills available in the
communities. 7. Less than 10 firms nationally with
capacity to implement such projects. 8. Projects too small to attract foreign
interest. 9. Logistics – due to remoteness of some
communities.
HINTERLAND ELECTRIFICATION PROCESS
WHY THE SOLAR HOME SYSTEM OPTION?
1. High network cost. 2. Low initial demand for
electricity. 3. Unavailability of reliable wind
data. 4. Hydro power option was
limited to some communities and needed costly network
5. High transportation cost for fossil fuels.
6. Individual solar PV system was least cost option.
BENEFITS
Improved lighting for after-dusk productive activities:
Studying / Reading Craft Making Sewing / Knitting
Power for operating small electronic devices for communication, information and entertainment:
Cell-phone Charger Radio Portable CD Player
SUSTAINABILITY PLAN
SUSTAINABILITY Institutional Framework
Training
Financial
Village Councils to manage project operation phase
Selected residents trained to maintain the PV systems
Each household to pay GY$500/mth to a fund
REPLICATION
2007 2008 2009 2010 2011 2012 2013 2014 2015
19,700 Home Systems
334 Home Systems in Pilot Projects
Number of Solar Home Systems Installed
(Mostly 65W Systems)
GOING FORWARD
Community Based
Electricity Systems
PV Mini - , micro-grids in central area
o Small Solar Farms o Wind Farm where viable o Mini- / micro-hydro where
available o Hybrid systems
Use
Provide energy for productive /
livelihood activities
Provide energy to support / enhance social services (water
supply, health services, education)
