Ill. Electric Energy (1, 2, 3, 4) (1) - lnstaUed capacity

The only available information is taken from doc. (4), issued in 1963 vhan the International Bank made a loan of .~ 7 mill ion to expand e1estric power facilities in Mauritius.

• E!CN.14!INR!104

Page 113

'ilie beneficiary of thc loan was the Centr'a.I ~l ectric:rt~y Board ( G. E.B. ), a semi-autonomous government co r-po r-at ion e stab). ished"in 1952 to consolidate the various electricity undertakings on the island.

Since 1956, GEB has been the sole public supplier of electricity on the i';land'and now serves about half the population.

GEBob't a i.n s most .of,·its energy re,ill.irement s ",fro;' its own plants, which nave a combined ..capacity 0:f'..a-hQ.uL3.o."OOOk'+-,·-of·which about half

is in hydrc plant s , It supplement s ..tltis ._ca.pacit;f;,_--_.. ~n the dry season,

_-~-.,... ..~-..-- . .

by purchases of power from private plants on .augar estates.

The loan helped to finance the construction of a 12,000 kIT

diesel power station at Port Louis, the capital city, and an expansion and improvements of the transmission and distribution systems.

The pr-o je ct increased the island¹s public supply by nearly a third, improving the efficiency of service in towns connected to the powbt network, and extending service to some addit ional commllIli.tie.s. It.is--·

expect ed tha1;·the-proJeet "ill meet the GEB power requirements until mid-1968.

The new station is equipped with two diesel generating sets of.

6,000 kU each. The "plant site is largE! enough to' permit e ...entual expansion of the 9tatio11 to 40,000 k'f..

The total cost of the'project was estimated at the equivalent of

$ 8.6 million, which g':Lir",s 'a specific investment of ;715.. per installed kilowatt.

The loan was given for a term of 20 year,",

at

an anmml-intere-St' rate of

5.5

per cent, including the one per cent commission allocated to the Bank's special reserve.
