The power cut last Tuesday in the centre and north of the country, which also affected South Africa and Zimbabwe, cost the Cahora Bassa Hydroelectric Company (HCB) an estimated US$1 million, AIM has reported.
The outage occurred at about 5:00 p.m. and was caused by the modernisation of the servers of the control system of the company’s generator sets, work that is currently underway but which has now been put on hold pending investigation of the breakdown.
In recent months, HCB has been implementing an investment programme called Capex Vital, which aims to refurbish the electric power system which, according to technical manager Moisés Machava, is at the limit of its useful life.
Machava explained that the modernisation of the servers has been developed with the technical help of the equipment manufacturer, General Electric.
The outage company cut the power supply to Cahora Bassa Hydroelectric customers, including Electricidade de Moçambique (EDM), ESKOM of South Africa and ZESA of Zimbabwe.
Machava said that it had been decided to suspend rehabilitation work to investigate the cause of the interruption, a process that could last until the end of the week.
Machava also said that the amount indicated as lost due to the interruption of power supply included lost revenue and penalties for the temporary non-compliance of contracts with customers.
