The e7 Fund has established an independent electricity supply
system utilizing photo-voltaic system at the W-Park, National Park
area laying across the national borders of Niger, Benin and Burkina
Faso in West Africa. The project intends to supply electricity to
hospital, dispensaries, ranger stations in the National Park area, and
local residents as well as to assure drinking water during the dry
season for the animals living inside of the Natural Park, including
elephants, lions and so on, for the purpose of the preservation of
nature. The project is one of the activities to contribute to sustainable
development with electricity surved by the e7 Fund, which is a non-
governmental organization formed by major utilities in the world
consisting of American Electric Power (USA), Electricite de France
(France), Hydro Quebec (Canada), Ontario Power Generation
(Canada), RWE (Germany), Ente Nazionale per lEnergia Electrica(Italy), Scottish Power (UK), Tokyo Electric Power Co. (Japan) andKansai Electric Power (Japan).

The major medical facilities in this area are Tapoa Djerma dispensary in
Burkina Faso serving for about 1,000 local residents, Karimama hospital for
about 20,000 local residents and Kompa dispensary for about 1,000 local
residents in Benin. These facilities play an important role in medical activities
in the local communities.
Electricity supply is utilized for lighting, to drive electric pumps to assure
drinking water (e.g., a 5,000-liter water tank and a 400-liter emergency medical
tank at Tapoa Djerma dispensary) and for refrigerators to store drugs and
vaccines. It is apparent that the project has contributed to the improvedmedical capabilities of hospital and dispensaries as well as to the improved
living standard of local communities. In addition, the project also served as the
measure for the preservation of nature. Animals in the Natural Park were
exposed to crisis of their lives when drinking water was exhausted in the dry
season. The project has supplied solar electricity to electric pumps which
supply water to the watering places at Perelegou, Niger to assure drinking
water both for the herbivore and carnivore living in as wide as 20,000-hectare
area.

The photovoltaic system consists of solar panels, battery, inverter and
wiring. With a rather small capacity from about 0.3 kW to 3.0 kW the
electricity plays an essential role in the local area.
This project was proposed by the e7 internally in 1998 followed by the
preliminary investigation initiated in March 2000 and it was started in June
2000. EDF took the lead in performing the project in cooperation with HQ,
ENEL, RWE and Kansai. The work in Niger was completed in May 2003,
Burkina Faso in June, 2003 and Benin in December, 2003. Subsequently,
the inauguration was held to take over the facilities to the local authorities.
In addition to funding from the major operating body e7, the project was
carried out with high-level support from the concerned three governments
as well as assistance from UNESCO and EU. It is one of good practices
supported by international cooperation. In spite of the bad condition in the
inland of Africa, the project work was proceeded in a smooth manner. It isdesirable that the governments of the developing countries will be
engaged in similar projects by extending the concerned areas taking into
account the lessons learned from this successful project.
