South Sudan and Mauritius have both announced measures restricting electricity consumption due to the fuel crisis triggered by the US and Israel's war in Iran, which is also affecting other countries across Africa.

South Sudan has begun rationing electricity in the capital, Juba, while Mauritius has imposed restrictions to reduce wastage especially in high-power consumption areas.

On Wednesday, Juba's main electricity distributor, Jedco, said parts of the city would start experiencing daily power cuts on a rotational basis.

Due to the ongoing Iran-US conflict... Jedco must proactively manage its available energy reserves... we are prioritising a strategic rationing of power, it said.

The island nation of Mauritius is heavily dependent on oil imports for generating its electricity, with a shortage reportedly triggering an energy emergency.

According to the government, a shipment of oil that had been due to arrive over the weekend did not materialise, leaving the country with only 21 days of stock.

Energy Minister Patrick Assirvaden said on Monday that the government had obtained alternative fuel supplies from Singapore that were due to arrive on 1 April and more later in the month, but at a higher cost.

South Sudan has some of East Africa's largest oil reserves, but the majority is exported, while it imports the refined product needed for fuel. According to the International Energy Agency, South Sudan generates 96% of its electricity from oil.

The power rationing comes on top of the intermittent cuts that have been ongoing since May last year due to maintenance operations.

Ereneo Mogga, an electrical engineer who lives in one of the worst affected parts of Juba, told the BBC that power often goes off at 16:00 and doesn't come back on until 04:00 the next day.

This paralyses most businesses, he said, adding that some of those who can afford it are switching to solar power.

It is very expensive though, but it costs less in terms of consumption.

With governments scrambling to find alternative sources of fuel, Zimbabwe has said it will increase the amount of ethanol it uses in its petrol, from 5% to 20%.

It has also announced plans to scrap some taxes on fuel imports to reduce fuel prices, which have risen 40% in less than a month.

One street vendor in the capital, Harare said the prices of everything had shot up since the war in Iran began.

Nicole Mazarura, who sells soft drinks from a push cart, told the BBC she can't raise the price of the drinks so she has to bear the loss, while her transport costs had doubled, depending on the time of day and where she orders her products from.

If transport costs go back to where they were, I can survive, she said.

In Ethiopia, authorities have ordered fuel supply companies to prioritise security institutions, major government projects, key industries and the manufacture of essential goods.

The Ethiopian Oil and Energy Authority's measures announced last week saw petrol stations prioritising public transport, as well as restrictions to conserve fuel.

Authorities in the Tigray region, where there are fears of a return to civil war, have announced a complete suspension of fuel supplies.

In Kenya, 20% of petrol stations are reportedly experiencing supply shortages.

An association representing petroleum outlets in the country has cited high demand for fuel because of panic buying, with stock levels running low.

Kenya's energy ministry on Wednesday denied that there was a shortage of fuel, accusing retailers of hoarding the commodity in anticipation of higher prices.

The minister, Opiyo Wandayi, also urged Kenyans not to engage in panic buying.

South Africa has sufficient supplies but warns a prolonged conflict could affect availability and prices in the coming months. The government statement has assured citizens that panic buying is unnecessary.

In summary, as nations adapt to the ongoing crisis, the consequences of rising energy costs and rationing measures are putting immense pressure on locals and businesses throughout the continent.
