| BURUNDI has very good cooperation with CHINA especially in technique and Economy.-From 1972.CHINA has promised to construct the first national SHP plant on the MUGERE river near Bujumbura (8MW). In 1982, this SHP began to output electricity.-Actually CHINA has accepted to finance the MPANDA SHP project (10.4MW)-CHINA has also accepted to build a technical university at Bujumbura to increase technical engineer staff.-There is many other works; health. Textile industry. Roads construction.This good and effective cooperation had been especially confirmed through the two last regular complete revisions of the MUGERE SHP even is some times the security on the field was disturbed. The also one has been supported by the CHINA government (more than 400,000US). Also, two Chinese staffs assisted by three Burundian operators are going on with preventive and curative maintenance of the equipments of this SHP plant.Burundi geographic informations and economic situation informations are shown in table I and table2. |
1 SHP in Burundi
1.1. Historic
- 1959: An overhead electrical line 70kV from RUZIZI I SHP plant of CONGO supplied
Bujumbura.
- 1982: The first national SHP plant (MUGERE 8 MW) constructed by the CHINA
Government has also sup-plied Bujumbura since May, 12. 1982.
- Since that date to 1988, eight (8) other SHP plants have been constructed
progressively to supply the main centers inside the country, as showed on the
national electric net-work map.
This network is actually supplied by- 9 national SHP with a total in-stalled
capacity of 30.9 MW,- 2 foreign SHP plants (one of SNEL-CONGO with 4 MW, another
of S1NELACCEPGL 13.3 MW) by two overhead HV lines.
All these 11 SHP assume the BURUNDI electricity supply by HV electrical lines:
110 kV, 70 kV, 35 kV, 30kV and 10 kV.
There is a thermal power station of total installed capacity 5.5 MW (2~ 1.5
MW, 2 ~ 1.25 MW) which has been constructed in June 1996 for scour supply of
the capital Bujumbura.
Actually there are 4 national in-terconnected SHP (RWEGURA, MUGERE, RUVVYIRONZA
and NYEMAGA) and 5 isolated SHP (GIKONGE, MARANGARA, KAYENZI, BUHIGA and SANZU).
1.2. SHP
See the table 3.

| Table2 Burundi Economic Situation Informations | |
| I. Natural resources | |
| 1 Ores | -Very few, not enough to be exploited by companies -Only there is a Nickel exploitation project in preparation-with a South-African company ENDOVER. |
| 2 Soil fertility | In general, the soil is not very fertile. |
| 3 Agriculture | -The most part(>95%) is a family small agriculture
for direct consumption. -A little part is for exportation: Coffee, Thee and Cotton agriculture. |
| 4 Forest and Reforestment | -There are some natural forest and the Government encourages the peoples to reforest. |
| II. breeding and Fishing | |
| -There is familial breeding of Cows, Pork, Goats, Sheep, Chickens, ˇˇ(for fumier, meat and milk resources).-Fishing is especially made in the Tanganyika lake (very good quality fish). | |
| III. Transport tines to foreign countries | |
| -Water line though the Tnganyika lake to reach the nearby ports of TANZANMIA (Kigoma), ZMBIA (Lusaka), MLAWIA (Mpulungu) and some small others of CONGO -sea area, no sea transport line-roads: there are roads to reach the neighbor countries but two of them are the most important roads for tank truck and transit goods carrying to reach Dares-Alam (ANZANIA) and Mombassa (KENYA) ports.Air lines: from the Bujumbura international airport | |
| IV. Tourism | |
| There are beaches (on the sides of the lakes),Sceneries, small parks, natural reserves, mountains, falls and small hydrographic tablishments. | |
| V. Industry or manufacturing | |
| -Most of them are in the capital Bujumbura. But some others
are in the rural area. -Drinks manufacture: BRARUDI, BRAGITA -Coffee manufacture: OCIBU, SODECO -Cotton production and manufacturing; COGERCO, COTEBU, RAFINA -The production and manufacturing; OTB -Sugar other small manufactures and workshops |
|
| VI. Trading | |
| The importation is greater than the exportation.The importation concerns the foreign manufactured products from China, Taiwan, Japan, France, Germany, Italia,ˇ.The exportation Concerns especially the coffee, the thee, the cotton. | |
| VII. Energy resources | |
| Hydro-energy is the most utilized. The total potential HP capacity is 300MW and the total already installed capacity is 30mW(10%).The petrol is imported (11cost: 0.8 US).Wood for heating (70%of the all used wood).Sun lotion is no exploited until now.Peat: used especially for cooking in big people center as schools, campsˇ. | |
* Two foreign SHP contribute to sup- ply in electricity the
Burundian inter- connected grid:
RUZIZI I: belongs to SNEL CONGO company (total installed capacity 39.7 MW, power
part to BURUNDI 4 MW) by a 70 kV over- head electrical line.
RUZXIZI II: belongs to SINELAC CEPGL (BURUNDI, CONGO, RWANDA) company (total
installed capacity 45 MW, power part to BURUND113.3 MW) by a 110 kV overhead
electrical line.
* Five SHP projects are presented.
-2002 to 2005: MPANDA SHP (10.4 MW) and KABU 16 SHP (20 MW).
- After 2005 two other SHP are projected: Jiji 003 (15.5 MW) and MULE 34 (16.5
MW).
-The 5~h is RUSUMO FALLS MHP plant (61.2 MW) which will be- long to the OBK
(BURUNDI, RWANDA, UGANDA, TANZANIA) international organization.
Moreover, our company, REGIDESO, is constructing HV lines to prepare for few
years the interconnection of all it's SHP. So, the BURUNDI will be electrically
sup- plied by one interconnected grid more reliable.
1.3 Electricity and Water
The electricity and water production and distribution are assumed by a national
company, REGIDESO.
- Total staff: 1200 persons,
- Service duration: 40 years. From this 30th of June will be the 40th anniversary.
There is another small public department (DGHER) which supply wa-ter and electricity
in rural small cities to promote the development of the rural areas.
2 Our Benefits in This Training Workshop
2.1 SlIP
In our companys, we are in two technical electrical services: power Production
(Mr NTUNZWENI-MANA Gagarine ) and network de-sign and planning (Mr NIYONGINGO
Nehemie). As technical staff, this training workshop has given us many detail
knowledge's as follows.
- The different structures of a SHP from design, construction until exploitation;
- The different inspections to prepare the revisions or the refurbishments;
- The abilities of CHINA (it's companies and research
centers, in particular HRC) to promote the SHP inside and in foreign countries;
- The CHINA cooperation about SHP promotion very useful for developing countries
(especially African countries);
- Complete case study presentation, our own case study: MUGERE SHP (near Bujumbura);
- The comprehensive exploitation of dams (water supply, irrigation, power generation,
flood protection, fishing, sightseeing... ).
2.2 Reception, Fisite and Tourism
CHINA (HRC) has made us a very good reception to be considered
as example. The manufactures visited (KVAERNER, LMMW) have given us opportunities
to realize the Chinese potential SHP partners to BURUNDI (REGIDESO). Tourist
sites, rural areas and cities visits have been for us opportunities to see the
East CHINA human activities and environment which are very good examples to
our country.
This training workshop has given us more knowledge and attention to pay on SHP
also the CHINA's ability to promote these stations among developing countries.
This is a very important thing to our country BURUNDI (and our company REGIDESO)
which use almost only SHP to produce electrical energy. It is sure that this
will be very useful for the already being and future hydropower.
3 Conclusion
Began by a very good reception, the SHP training workshop has been successfully
made. HRC has used all the means to disponibilize highly qualified and experimented
teachers to give us their knowledge in SHP: technical design, business and trading.
It is sure that this improves for us how to serve our country (particularly
our company REGIDESO) when we will be back.
This contribution effort among developing countries has merited our greatest
congratulations to CHINA People Republic Government, particularly to HRC.
About these training workshops, we would like to express the following recommendations.
- May such training workshop go on until outreach the all (developing) countries>
It is also a way to increase their development.
- It is desirable to be created a HRC intemet site for technical works, publications.
This will be very useful for us and for others even if fare we are. It will
be a great contribution to develop the all world especially our country (among
developing counties) in Hydro Plants.
Last but not least, we could not finish our presentation without ex- pressing
our sincere thanks to CHINA, especially HRC and all it's staff, for all the
effort used to receive, to accompany and to teach us from the beginning until
the end of this training workshop. We go back with the very distinguished fruit
of your laborious work that we carry very honestly to our country. It gives
us more ability to the works of our company.
To end, we thank to all the representatives of CHINA People Re-public Government,
TCDC, the representatives of HRC, all the HRC's staffand our friends trainees.
