ZESCO Limited has opened the 330 Kilovolt inter-connector between Zambia and Zimbabwe in order to protect the local power system from external disturbances.
ZESCO Senior Manager for Electro technical services Christopher Mubemba told Journalists at a media briefing in Lusaka today that the decision follows an external disturbance on the local system on 6th September resulting in the loss of power supply to Eastern, Northern and Lusaka provinces.
Mr. Mubemba said as a result of the disturbance two machines at Kariba North Bank power station tripped resulting in a loss of 360 mega watts.
He explained that the disturbance also resulted in the loss of transmission lines and distribution loads in Northern, Eastern and some parts of Lusaka and Southern provinces.
He noted that the opening of the inter-connectors entails that Zambia will now be required to carry the full power reserves to avoid national power blackouts.
Mr. Mubemba added that when interconnected ,the country’s required reserve is half as the remaining half comes from Southern African Power Pool (SAPP) region .
Mr. Mubemba however disclosed that the opening of the interconnectors also entails that there will be more load shedding in the country as a region as a whole has a power deficit particularly during peak demands.
The 330 KV interconnectors were opened yesterday and ZESCO will continue to monitor the situation so that the interconnectors are closed as soon as the situation improves.
