JOHANNESBURG, Sept 5 Reuters The South African rand weakened on Tuesday against a stronger dollar as the country suffered the worst power cuts on record.

At 1516 GMT, the rand traded at 19.2350 against the dollar , about 0.5 weaker than its previous close.

The dollar last traded more than 0.6 stronger against a basket of global currencies.

With the U.S. closed … most markets were stable, except the rand that fell sharply, said Rand Merchant Bank analysts in a research note.

The rand tumbled after South Africa39;s struggling state utility Eskom reinstated the worst rolling blackouts on record, which mean up to 12 hours of power cuts for most households per day.

In the second quarter, when Eskom somewhat eased the levels of outages, the country39;s economy recorded a greater than expected expansion, local data showed on Tuesday.

SP Global survey showed South Africa39;s private sector activity grew for the first time in six months in August as improved demand led to firms boosting output.

On the stock market, the Top40 and the broader allshare indexes closed around 0.5 lower.

South Africa39;s benchmark 2030 government bond was weaker in afternoon deals, with the yield up 7.5 basis points to 10.410.
