IMPROVING LIVES THROUGH DATA ECOSYSTEMS
How municipalities help to keep the lights on
Acting as intermediaries, municipalities buy electricity from Eskom in bulk and then re-sell it to various customers (including homes, businesses and government). According to the utility, 42% of the electricity it generated in 2013/14 was sold to redistributors, such as municipalities1.
Almost a third of income earned by municipalities (R21,9 billion) in the quarter ended June 2015 was through electricity sales, according to Stats SA’s latest Quarterly financial statistics of municipalities report2.
Municipalities spent R15,2 billion to purchase electricity from Eskom, translating into a surplus of about R7 billion. Surpluses from these sales are used to offset costs incurred in the provision of other rates and general services (e.g. cemeteries, fire brigades and libraries).
Municipalities purchased 21% more electricity in the June 2015 quarter compared with the March 2015 quarter, rising from R12,5 billion to R15,2 billion. Contributing to this increase was the usual peak in electricity demand experienced in the winter months, as well as rising electricity tariffs.
What is striking is the dominance of South Africa’s eight metropolitan municipalities. The metropolitan councils purchased 65% (about R10 billion) of all electricity purchased by local government, despite only 40% of South Africa’s population residing in these areas3.
Johannesburg purchased the highest amount of electricity, which was the highest of any municipality, contributing 15% of the national total, followed by Ekurhuleni (13%), eThekwini (11%), and then Cape Town and Tshwane (both 9%).
It is important to note that not all municipalities take on an intermediary role. According to Eskom1, 58% of the electricity it generated in 2013/14 was sold directly to industrial (25%), mining (14%), international (6%), residential (5%), commercial (4%) and other (4%) customers, without the help of local government. Of the 234 municipalities shown in the map earlier, 58 did not purchase electricity during both the March and June quarters of 20154.
