In November 2022, the National Energy Regulator of South Africa (Nersa) awarded an electricity trading license to The Energy Exchange.<\/p>\n\n\n\n
In March 2023, Rand Merchant Bank (RMB) announced it had acquired a 25% shareholding in Remgro\u2019s Ubiquity Energy platform, the holding company of EXSA.<\/p>\n\n\n\n
The company started selling electricity to South African companies in June 2023, connecting its pipeline of buyers and sellers.<\/p>\n\n\n\n
EXSA provides electricity generators with a single market for their surplus capacity, making it easy for them to convert this capacity into revenue.<\/p>\n\n\n\n
Energy consumers, in turn, are given more control over their energy costs, more certainty around future pricing, and potentially better defences against interruptions.<\/p>\n\n\n\n
Licensed energy generators feed surplus electricity into the national grid, and customers draw the requisite energy.<\/p>\n\n\n\n
When energy is purchased from the EXSA, the amount of electricity generated and consumed is measured in real time.<\/p>\n\n\n\n
Energy Exchange customers are then charged for the energy they consume at the agreed rate, which is typically more affordable than most alternatives.<\/p>\n\n\n\n
Customers can choose to purchase all or part of their energy through EXSA. Its blended supply and aggregation model brings savings over purchasing renewable energy from a single plant.<\/p>\n\n\n\n
It also provides redundancy. If a single plant\u2019s load temporarily reduces, the exchange can sell energy from another plant to a client to mitigate or entirely avoid downside price risk.<\/p>\n\n\n\n
EXSA also has an aggregated agreement with Eskom, ensuring that clients do not incur costs for surplus energy.<\/p>\n\n\n\n

<\/a><\/figure>\n\n\n\nLast year, the EXSA board appointed a new executive team, led by new Chief Executive Wayne Cowie, to head the company.<\/p>\n\n\n\n
The team includes Aishah Gire as COO, Monique Jordaan as head of legal and commercial, Shailin Moodley as head of product, Henri van Eetveldt as head of business development.<\/p>\n\n\n\n
Remgro executive Pieter Uys is board chairman, alongside Remgro\u2019s Willem van Wyk and Rekha Sinath, and RMB\u2019s Dario Musso and Kenneth Oboni-Ouma.<\/p>\n\n\n\n
Cowie, who took the reins on 1 October 2024, said he was excited to get stuck in alongside his team and help enable South Africa\u2019s transition to clean energy.<\/p>\n\n\n\n
Before joining the Energy Exchange, he served as Managing Director for BlueWave Solar\u2019s project finance and merger and acquisition activities.<\/p>\n\n\n\n
\u201cWe bring together a wealth of experience across energy, infrastructure, finance and technology, united by a shared vision for a sustainable future,\u201d EXSA said.<\/p>\n\n\n\n
After Cowie took over, the company rebranded from Energy Exchange of Southern Africa to EXSA and launched a new brand identity, with a new logo and website.<\/p>\n\n\n\n
\u201cWe\u2019re not just launching a redesigned website. We\u2019re re-energising our commitment to a brighter energy future for Africa,\u201d it said.<\/p>\n\n\n\n
\u201cAt EXSA, we believe in partnership, innovation, and a sustainable approach to solving Africa\u2019s energy challenges.\u201d<\/p>\n\n\n\n
EXSA’s diversified renewable energy<\/h2>\n\n\n\n![\"\"](\"https:\/\/businesstech.co.za\/news\/wp-content\/uploads\/2025\/05\/EXSA-1024x576.jpg\")
<\/a><\/figure>\n\n\n\nEXSA stated that, as a NERSA-licensed electricity trader, it has developed a diversified renewable energy portfolio that provides numerous benefits.<\/p>\n\n\n\n
The energy exchange sources energy from a diverse network of Independent Power Producers (IPPs) across South Africa.<\/p>\n\n\n\n
By aggregating energy from multiple sources, EXSA creates a robust portfolio that maximises overall energy savings and contributes to the consistency of energy supply.<\/p>\n\n\n\n
\u201cThis diversified approach enhances reliability and allows us to tailor solutions to your individual needs, offering flexible contracts and competitive pricing,\u201d it said.<\/p>\n\n\n\n
It uses analytics protocols, multivariate optimisation, and portfolio-level design tools to ensure the energy supply is tailored to a customer\u2019s specific needs and goals.<\/p>\n\n\n\n
EXSA added that it is exploring new technologies, such as energy storage solutions, to enhance its offerings and provide you with greater reliability.<\/p>\n\n\n\n
EXSA delivers electricity by wheeling it from a generator to an end-user in another area using an existing transmission or distribution network.<\/p>\n\n\n\n
This delivery may also happen across multiple different distribution networks, such as through Eskom to a municipality.<\/p>\n\n\n\n
Today, EXSA is a market-leading supplier of grid-connected renewable energy to South African corporates, industrials and SMEs.<\/p>\n\n\n\n
It said its wind and solar energy help companies meet their Net Zero ambitions at a lower price than Eskom charges.<\/p>\n\n\n\n
\u201cWe make our customers\u2019 green energy procurement experience seamless, sustainable and cost-effective,\u201d the company said.<\/p>\n\n\n\n
