Moza power utility seeks power trade-off with Zimbabwe, Zambia

Mozambique’s Hydro Electrica de Cahorra Bassa has offered Zimbabwe and Zambia power imports in exchange for further reduced power generation by the two countries at their Kariba Dam hydro plants, state media reported Thursday.

Cahorra Bassa Dam is overflowing following recent cyclone-induced floods, and authorities in Mozambique favour having Zimbabwe and Zambia storing more water in Kariba Dam, which is upstream of Cahorra Bassa on the Zambezi River, to reduce inflows into the downstream dam and thus protect the infrastructure at Cahorra Bassa.

The offer for power comes at a time the Zambezi River Authority (ZRA), which administers Lake Kariba, and the Zambezi River, which straddle the two countries, has instructed the two power utilities that generate power at Kariba Dam — Zimbabwe Power Company (ZPC) and ZESCO of Zambia — to cut power generation because of the 2018/19 El Nino induced drought hitting southern Africa.

The ZRA has rationed water consumption by the two companies to 358 MW for Zimbabwe and 392 MW for Zambia, resulting in the two countries’ introducing load shedding since May and causing distress in industries and among domestic users.

ZRA chief executive Munyaradzi Munodawafa told a delegation led by Zimbbwe’s new Energy and Power Development Minister Fortune Chasi recently that Mozambique had offered power to Zimbabwe and Zambia in lieu of reduced discharge from Lake Kariba.

The two countries may get as much as 500 MW without the parties involved having to exchange any or significant amounts of money for the deal.

“We should be going to discuss that issue. We should be going with ZESA, ZESCO and their transmission people so that we sit together and agree how much Hydro Cahora Bassa can give out without requesting for money and without also the transmission requesting for wheeling charges and all that,” he said.

ZESA is the parent company of the ZPC.
