Cape Town has officially launched a R220 million solar and battery storage facility in Atlantis, marking what the City describes as South Africa’s first metro-built hybrid power plant.
The new Helderhoop Solar and Storage Power Plant is more than another renewable energy project for Cape Town. For Atlantis, it arrives as the community marks its 50th anniversary, while its name carries a message of hope chosen by a local matric learner, Cape {town} Etc reports.
Cape Town Mayor Geordin Hill-Lewis launched the facility on Thursday, 8 October, alongside Mayoral Committee Member for Energy Alderman Xanthea Limberg.
The plant is expected to help the City reduce its dependence on Eskom while producing electricity at a lower cost.
Hill-Lewis said the cheaper power could save Cape Town residents at least R400 million over the next 20 years.
A major renewable energy project in Atlantis
The Helderhoop facility includes 12 850 solar panels and two utility-scale batteries, covering approximately 15 hectares.
That is roughly equivalent to the size of 21 rugby fields, giving an idea of the scale of the project.
The City has invested R220 million in the facility, which is now complete and operating under controlled test conditions as it moves through the commissioning process.
For Atlantis, the development also brings a significant employment milestone. Around 305 jobs were created during construction, with workers gaining skills and experience in renewable energy infrastructure.
Why the name Helderhoop matters
The name of the plant was not chosen by officials behind closed doors.
The City held a public competition, with the winning proposal coming from Vinolio Cloete, who was a matric learner at Saxonsea High School when she entered.
Her proposed name, Helderhoop, means ‘Bright Hope‘.
Cloete linked the name to what solar energy could mean for Atlantis, including cleaner energy, employment opportunities, progress and a better future for the community.
That gives the project a distinctly local identity. Instead of simply carrying the name of a location or technical project, the plant now has a name connected to the aspirations of a young person from the community where it stands.
Cape Town’s wider push to reduce Eskom dependence
The Atlantis plant forms part of a broader effort by the City to diversify where its electricity comes from.
Cape Town recently became the first city to buy electricity on the open market through an initial Independent Power Procurement Programme of up to 200MW. The City says two power purchase agreements signed under the programme offer savings of up to 21% compared with Eskom rates.
The City also plans to procure up to 500MW from energy traders and aggregators, alongside additional generation from waste-to-energy producers.
For residents, the broader objective is straightforward: reduce exposure to Eskom’s electricity costs while strengthening the city’s energy resilience.
Residents are already feeding power back into the grid
Cape Town’s energy strategy is not limited to large municipal projects.
Through its municipal small-scale embedded generation programme, 2.2MW of solar generation has been installed across several municipal sites, with a target of 25MW over the next two years.
The City has also enabled residents and businesses with excess solar power to sell electricity back to the municipality in exchange for municipal bill credits and cash.
Since June 2024, the City says participants have earned R67 million from selling 150GWh of excess solar power.
More than 250MVA of rooftop photovoltaic capacity has also been installed across Cape Town, helping reduce pressure on the electricity grid.
More projects are planned
The City says it is also preparing for another major municipal renewable energy project.
Feasibility studies have been completed for a proposed 70MW hybrid solar PV and battery storage plant at Paardevlei, with the City aiming for the facility to be developed by 2029.
Cape Town has also traded more than 1 700MWh of electricity between power producers and consumers through energy wheeling since 2024.
The municipality says its energy-efficiency programme has already saved more than 427GWh of electricity, generating approximately R625 million in savings through measures including streetlight and building upgrades and rooftop solar installations.
Atlantis gets more than a power plant
The Helderhoop launch comes at a significant moment for Atlantis, which is celebrating its 50th anniversary.
The City highlighted several other developments in the area, including the completed R31 million upgrade to Wesfleur Stadium, continued upgrades to local MyCiTi bus stops and ongoing commercial investment in the Atlantis Special Economic Zone.
The City has also contributed 96 hectares of municipal land to the Atlantis SEZ.
Against that backdrop, Helderhoop represents another investment in the area’s future – but this time through energy infrastructure.
For Cape Town residents, the bigger question will be whether projects such as this can translate into more affordable and reliable electricity over the long term.
If the City’s projected savings are achieved, the benefits could eventually reach households through lower electricity costs, while the additional renewable generation and storage could strengthen the city’s ability to manage its energy needs.
For Atlantis, however, Helderhoop already has a meaning that goes beyond megawatts and solar panels.
It carries the name ‘Bright Hope’ – chosen by a local young person – at a time when the community enters its next 50 years.
