Zimbabwe’s economic difficulties are being made even worse with another round of power cuts.

The country has been dealing with power outages for a long time, but recent cuts by the Zimbabwe Electricity Supply Authority (ZESA) have led to the worst energy crisis the country’s seen in three years.

ZESA introduced “load-shedding” power cuts last month amid low water levels at the Kariba hydroelectricity station. Zimbabwe’s energy situation has also been made worse by crumbling energy infrastructure and a lack of funding for energy imports. ZESA schedules these power cuts for specific five-hour stretches of time in the earlier and later hours of the day, for example 5:00 AM to 10:00 AM. Despite the schedule, the cuts have often lasted longer. According to ZimLive, at least one family had no electricity from Friday through Sunday last week. As a result, Energy Minister Fortune Chasi pledged to reduce the outages, but urged the public to pay their bills due to ZESA so the authority can buy more power from neighboring countries. ZESA reportedly paid off a $10 million USD debt to South Africa earlier in June.

The Zimbabwean economy has been adversely affected by years of political isolation. Longtime President Robert Mugabe was ousted in 2017, sparking hopes for economic changes and an end to the country’s economic and political isolation. Mugabe’s successor President Emmerson Mnangagwa has promised to attract investors to create sustainable growth that would repair the country’s broken public services and return to a situation where Zimbabwe has a national currency that isn’t subject to hyperinflation. Zimbabwe banned the use of foreign currencies, including the US Dollar, in June alongside a pledge to create a new national currency. The Zimbabwean Dollar was scrapped in 2009 after the currency reached epic levels of inflation, with some banknotes reaching $100 trillion.
