Statistician general Pali Lehohla said the income from sales of electricity was 29.5 percent of the total and amounted to R20.2bn.
“The increases were mainly due to tariff increases,” he said in Pretoria releasing the Quarterly Financial Statistics of Municipalities (QFSM) report.
“The sales of electricity was R1.3 billion higher than the amount received in the previous quarter.”
In the first quarter of 2014 the sale of electricity was R18.9bn. The second quarter saw an increase of 6.9 percent.
Other contributors were grants and subsidies R14.9 bn or 21.8 percent; property rates R11.4bn or 16.7 percent; other income R10.5bn or 15.4 percent; sales of water R6.7 bn; sewerage and sanitation R2.7bn; and refuse removal R1.9bn.
Water sales increased by 1.4 percent.
The province that consumed the most electricity and water was Gauteng, said Lehohla.
“There is some migration to Gauteng that causes some interesting difficulties,” he said.
Gauteng contributed R8.5bn or 42 percent to the sales of electricity, followed by KwaZulu-Natal with R3.6bn and Western Cape R3.4bn.
The money received in the form of grants and subsidies from provincial and national government decreased by R3.4bn from R18.3bn in the first quarter of the year.
Gauteng received the largest portion with 37 percent, followed by KwaZulu-Natal 18 percent, Western Cape 12 percent and the Eastern Cape 10 percent.
He said the province with the lowest share of grants and subsidies was the Northern Cape, which received one percent, about R0.1bn.
