Cape Town 500MW electricity tender opens door to private power traders
By Kris Van Der Bijl
CAPE Town is three weeks from the closing date on a tender that, if it succeeds, will make it the first South African municipality to procure electricity at scale directly from licensed energy traders, bypassing Eskom through a mechanism no metro has attempted before. Bids close on 13 May 2026.
The 500MW procurement, structured through power purchase agreements with licensed traders, opens a direct commercial channel between private energy markets and a major municipal buyer.
Alderman Xanthea Limberg, Mayoral Committee Member for Energy, was constrained by the tender’s active status.
“As the process is still so active, we cannot speculate or provide too many details currently,” her office said.
A two-stage process and a fallback
The procurement runs in two stages. Stage 1, closing 13 May, does not purchase energy directly. It establishes a panel of compliant traders.
“The panel tender was advertised on 13 February 2026 and closes on 13 May 2026, with evaluation expected to conclude thereafter. Following the panel award, Stage 2 commences,” Limberg confirmed.
In Stage 2, panel members bid competitively on specific energy requests from the City.
If Stage 1 produces no compliant bids, there is something of a contingency plan.
Limberg notes: “In this first stage, we are confident that we will receive compliant bids to form a panel of Energy Traders who will further competitively bid on requests by the City for procurement of energy. Should no compliant or responsive bids be received at this stage, the City will consider alternative market options while remaining committed to achieving its Energy Strategy objectives,” Limberg said.
Note that alternatives remain unclearly specified.
The questions left unanswered
The City has stated previously that pricing must undercut Eskom’s tariff for the tender to proceed.
On whether the market will deliver competitive bids, Limberg’s office said the City would evaluate proposals after the closing date and went no further.
On timelines, the response was just as cautious, noting that, “The City has a multi-pronged approach and is working hard to ensure that we achieve our objectives,” Limberg said.
“The City stresses that this is a novel exercise. The compounded effect of delivering on our Energy Strategy will result in benefit to all our customers in the near future.”
For context, those with knowledge of the process suggest that tangible benefit to ratepayers is unlikely before 2028, subject to variables and procurement processes playing out as planned.
These are defensible positions for a live procurement. They do, however, leave the market with less visibility on the commercial logic behind a transaction of this scale and novelty.
The replicability question
Limberg was more forthcoming on knowledge-sharing with other municipalities,
“The City actively participates through organised seminars, conferences, forums, workshops, as well as ad hoc collaboration meetings to share our experiences and lessons learned with other municipalities and various spheres of government,” she said.
“We recognise that knowledge sharing is multi-directional and remain open to such dialogue as we navigate this novel space within the South African municipal environment.”
What the sector is watching
For Western Cape industrial and commercial ratepayers, among the most exposed to Eskom tariff escalation in the country, a functional trader panel delivering below-Eskom pricing would be of obvious use if properly realised.
