The Zimbabwean government is reportedly negotiating with neighbouring Zambia for additional power imports.
The development comes after indications that Kariba South Power Station might switch off due to low water levels.
Apart from the Zambia deal, Zimbabwe is banking on the expected coming online of Hwange unit 7 with an additional 300 megawatts (MW) next month.
Tests are reported to have been run although indications are that after the formal commissioning, the plant will run gradually until it optimises.
Zambia and Zimbabwe have a combined generation capacity of 2 130 megawatts at Kariba, which is on the Zambezi River that separates the two countries.
In July, Zambia declared that it had a surplus of about 1 000 MW.
According to the Zimbabwe Power Company website, Hwange Power Station is generating just 245MW, while other power stations Harare, Bulawayo, Munyati and Kariba are generating 11MW, 0MW, 14MW and 854MW, respectively, to give a total of 1 124MW, against a peak demand of 2 200 MW.
The move to engage Zambia comes after the Zambezi River Authority (ZRA) chief executive officer Munyaradzi Munodawafa said Zimbabwe had exhausted its 2022 water allocation necessitating the shutdown of the Kariba South Bank Power Station.
However, former Finance minister Tendai Biti said Zimbabwe needed a fresh 2 000MW on its national grid to meet rising demand. He told NewsDay:
You should just strike off Kariba, forget about it and look at new projects such as Batoka which can give you 2 000MW split in half between Zimbabwe and Zambia.
He said the balance comes from alternative sources, including wind, solar and independent power producers.
