Building a sustainable energy future for Cape Town

The City of Cape Town is committed to efforts to reduce city-wide electricity consumption, reduce the burden of electricity costs to households and the economy, reduce CO2 emissions, improve energy security and support job creation.  

The City’s Electricity Savings Campaign, which started in 2009, targets residential and commercial consumers. It aims to reduce city-wide electricity consumption and the related CO2 emissions, and to increase energy security through a wide range of behavioural and technological changes. Energy efficiency is pivotal to a more affordable, sustainable and secure energy future for Cape Town.

The programmes and projects the City’s runs as part of the Campaign, are contributing to achieving the City’s ambitious Energy2040 Goal. This includes the target of 37% reduction (21% from energy efficiency alone) in harmful carbon emissions which are contributing to global climate change, off the business-as-usual baseline scenario. It is envisaged that there will be  500 000 solar water heaters and heat pumps installed in across Cape Town by 2040.

The City’s Electricity Savings Campaign, Solar Water Heater Programme and Solar PV Promotion Programme are key aspects of this drive and this website is our online platform for communicating to the public.

Solar Water Heater (SWH) accreditation and marketing programme

The SWH Programme is aimed at promoting the installation of high-pressure residential solar water heaters and improving the reliability, quality and standards of products and installations.  

The City wants to see large-scale installation of solar water heaters because we know that it’s the one thing that can make the most difference in residential energy efficiency to achieve savings, reduce electricity use and the negative environmental impact of our predominantly coal-fired power, and it strengthens the local green economy.

The Programme helps residents by carefully vetting solar water heater service providers and accrediting those meeting rigorous standards for their competence, quality of products used, quality of installation, customer service, maintenance and other aspects of their business. These Accredited Service Providers also agree to uphold a code of conduct regarding how and what they sell, how they service their customers, how they respond to any complaints and more. While any service provider based in the Cape Town area can apply for accreditation at no cost, only those meeting these standards will be accredited. 

The programme also involves promoting solar water heater uptake through training, communication and educational campaigns, monitoring the performance of the selected service providers and undertaking quality control. 

If you are a SWH installer and wish to apply to join the Programme, feel free to contact to be added to the waiting list and informed when applications reopen. 

See our FAQ’s for more information about the Programme and what accreditation requirements our service providers have to meet. 


The City of Cape Town would like to thank Sustainable Energy Africa for their invaluable contribution to the City’s Residential High Pressure Solar Water Heater Programme

Sustainable Energy Africa is a non-profit organisation based in Cape Town, has contributed significant expertise and constant support to the City’s Programme by providing technical support, project management support and by securing funding for the Programme.

In particular the City would like to acknowledge the critical role that Andrew Janisch (who has sadly passed away) played with such dedication in getting the programme up and running.

We would hereby like to gratefully acknowledge the generosity and support of these funders in the past: UNEP (United Nations Environmental Programme); EEP (Energy and Environment Partnership Programme with Southern and East Africa); REEEP (Renewable Energy and Energy Efficiency Partnership).

More recently, we’d like to thank the Friedrich Naumann Foundation for Freedom for their generous support.
