Zambia’s
power company Zesco on Wednesday began importing 148 megawatts of electricity
from a gas fired generator based in Ressano Garcia in southern Mozambique.The
gas is extracted from the Pande and Temane fields in Inhambane province and
piped to the Mozambique – South Africa border where the British based company
Aggreko has its generator. The electricity is then transmitted to Zambia along
the existing transmission lines of the Southern African Power Pool (SAPP).Zambia’s
decision to import the electricity is a reaction to a severe power shortage.
This is not only affecting citizens, but is also hitting the key mining sector.
The economy is already in serious crisis as the price of copper, the metal that
contributes nine per cent to the country’s Gross Domestic Product, has dropped
to a six year low.However, the situation has deteriorated even further due to a
severe power shortage. In large part this is due to drought starving the Kariba
dam on the border with Zimbabwe. The shortage of water at Kariba has forced
Zesco to cut output from its hydroelectric power station from 500 to 305
megawatts. There are fears that unless the mining companies drastically cut
back their power consumption the turbines will have to be switched off in
November if the dam falls to minimum level.Analyst Greg Mills, writing in the
online newspaper the “Daily Maverick”, blamed Zesco and its Zimbabwean
counterpart for continually using more water from the dam than planned. He
pointed out that “it seems that Zesco has been operating the intended peaking
units much more than the planned three to four hours a day. This means they’ve
needed to use more water, resulting in low reservoir level”.His analysis is
that at current operating levels, the Kariba dam could continue operating until
the end of the year when it is hoped that rains will replenish the reservoir.Strangely
enough, the Zambian government claimed that the power Zesco is importing comes
from an Aggreko ship moored at Beira. This was the story given to the Zambian
media on Tuesday by Chief government Spokesperson Vincent Mwale, after a
Cabinet meeting. However, when AIM contacted Aggreko the company confirmed that
the power comes, not from Beira but from Ressano Garcia.
