Power Heroes Programme

Residential and small commercial customers in City-supplied areas will soon be able to sign up to be Power Heroes and help Cape Town avoid up to one stage of load-shedding as part of the City’s overall load-shedding mitigation plan.

What is the Power Heroes programme?

The Power Heroes programme forms part of the City’s Demand Response Programme, which aims to protect our customers from load-shedding by lowering electricity demand, while we work on getting additional generation onto the grid.

The programme, focusing on the installation of smart meter devices that can be operated remotely by the City’s Network Control Centre, aims to target a total of 60MW in demand reduction, which means that, once enough customers have signed up, all City-supplied areas can avoid up to one stage of load-shedding.

Switching off non-essential loads, such as geysers and pool pumps, when the electrical network is constrained is one of the most cost-effective ways to reduce demand and mitigate load-shedding. For participating Power Heroes, this means they get better visibility on their electricity consumption to enable energy savings and, more importantly, they become part of the solution by working together to reduce the impact of load-shedding in Cape Town.

How the Power Heroes Programme works?

The tender for the programme has been awarded to a third party aggregator, the Ontec Karebo Joint Venture (JV), for implementation and management. Once contracting has been concluded, the Ontec Karebo JV will be responsible for recruiting customers, installing devices and managing load reduction when needed by the City.

Participation is voluntary and is subject to prequalification criteria, as there is a limited number of smart meter devices and we need to ensure that we get optimal load reduction from the customers that participate. You can register your interest here.


Customers participating will sign a contractual agreement with the Ontec Karebo JV, outlining the participation arrangements. The City will not be involved in this agreement. The Ontec Karebo JV will then install smart devices, free of charge, on non-essential appliances, agreed to by the customer. At a household level, these are typically electricity-intensive items such as geysers and pool pumps.


When the City is required by Eskom to move to a higher stage of load-shedding, the required load reduction will be implemented from the City’s Network Control Centre.


The main incentive for customers to participate in the Power Heroes programme is the ability of the City of Cape Town to eventually protect City-supplied customers from the effects of one stage of load-shedding, once enough customers have signed up and are participating.


The City’s load-shedding mitigation using the Steenbras Hydro Pumped Storage Scheme will continue to be implemented and all work continues on the City’s plans to end load-shedding over time.

Who can sign up to be a Power Hero?

Residential and small commercial customers in the City of Cape Town’s supply area are eligible to participate in the programme. Certain areas will initially be targeted depending on their load-reduction potential, and in alignment with the City’s pre-defined load-shedding blocks. 


Residents in Eskom-supply areas, and City-supplied large commercial and industrial customers will not be able to participate in Power Heroes. The City does have a Large Power Users (LPU) curtailment programme, for more information on this,  contact us.

How to join?

Once the contract with the service provider, the Ontec Karebo JV, has been concluded, the programme will be rolled out in phases giving the Ontec Karebo JV time to sign up customers and procure the smart devices. 

Joining is voluntary – there is no obligation to sign up if you are contacted.


Once the pre-qualification of customers is completed, the Ontec Karebo JV will arrange to install the smart devices.

Ontec-Karebo will be in contact. Once the contractual elements have been concluded Ontec-Karebo will communicate further information.

Choose to be a hero

Your participation will help the City avoid the effects of load-shedding on our economy and does not cost you anything. This all forms part of the City’s interventions to end load-shedding over time.

Thank you Team Cape Town!
