Athlone Power Station
Here’s a breakdown of what happened to the Athlone Power Station (APS), the role it played in Cape Town’s electricity supply, and what the future holds for the site.
1. What it was and its significance
- The Athlone Power Station was a coal-fired power station located in Athlone (Kewtown) in Cape Town, operated by the City of Cape Town.
- It was commissioned in 1962, originally with six turbines and a nominal capacity of 180 MW.
- Between about 1985 and 1994 the station was held on standby (“mothballed”), then from 1995 it resumed generation with reduced capacity (~120 MW) until decommissioning.
- It had a distinctive physical presence: large brick generation building, two ~99m chimneys, and cooling towers (fed by reclaimed sewerage-water) visible from the N2 highway into Cape Town.
- It played a strategic backup role: although not a large proportion of Cape Town’s total electricity generation, it was used during peak demand periods and to supply when the national grid (Eskom) supply was unstable.
- According to a 2005 energy paper: “The Athlone power station … is no longer regarded as a secure supply and consequently the municipality has decided to close that power station down.”
- Its location and fuel transport cost made it less economical compared to larger inland stations supplying Cape Town via transmission.
In short: APS was an important local power-generation facility, especially for backup/peak usage, and had both technological and historical significance for Cape Town’s energy infrastructure and industrial heritage.
2. What happened (decommissioning & demolition)
- The station ceased generation in 2003, because of its age, required investment, and changing economics.
- In February 2010 one of the cooling towers started showing structural failure (reinforcement rings collapsed). The city then decided to demolish the two cooling towers soon after.
- On 22 August 2010, the iconic cooling towers (nicknamed “the two ladies of Athlone”) were imploded and reduced to rubble in about eight seconds.
- Post-demolition, the main generation building and chimneys remained standing (as at last public update) and the site remains a large parcel of industrial land.
- There were environmental, structural and heritage concerns: e.g., asbestos exposure inside the station among workers.
Thus, APS moved from active generation → standby → decommissioning → partial demolition, leaving a large site awaiting redevelopment.
3. What’s planned for the site
There are several, possibly competing, visions for the future of the Athlone Power Station site. Key points:
a) City’s vision: green energy / utility hub
- According to the City’s Draft Spatial Development Framework (May 2022): the APS site is “being explored for the continued use … for utility purposes predicated on renewable and sustainable energy technologies … i.e., the site is being envisioned as a green energy hub.”
- The intention: integrate utilities, battery storage, leverage the site’s sunk infrastructure (rail, transmission/distribution) to support the green economy, create jobs and transform the City’s energy footprint.
- In 2023/24, the City reiterated that the site would “assist in the transformation of the City’s energy footprint and support economic growth and the provision of basic services.”
b) Housing/ mixed-use redevelopment proposals
- Residents and civic groups have pushed for housing, job creation, mixed-use development (retail, trade “grand bazaar”, training & cultural centre) on the site.
- Earlier (2006) concept: the City proposed the site could be transformed into a large “mixed-node” development with residential units (~3000 units), cultural/arts complex, boutique hotels, etc.
c) Heritage protection versus redevelopment conflict
- In 2022, Heritage Western Cape (HWC) declared the entire Athlone Power Station site provisionally protected as a provincial heritage site (PHS), due to industrial heritage significance (chimneys, building, infrastructure).
- The City is challenging this heritage designation in the Western Cape High Court, arguing the blanket protection hampers development plans.
d) Current status and constraints
- The site is still re-zoned/planned; full decommissioning and environmental cleanup must precede major redevelopment.
- The heritage protection order is a major roadblock to large-scale demolition or redevelopment that doesn’t respect the industrial heritage.
Summary: The preferred future is a green energy/utility hub with possible mixed-use (housing, cultural, job creation). But the process is delayed by heritage designation, site cleanup/decommissioning issues, and discussion with local stakeholders.
4. Why this matters
- For Cape Town’s energy infrastructure: although APS was no longer economically viable as a coal station, its decommissioning signals the shift away from local coal generation toward larger grid transmission and newer technologies.
- For land use & urban regeneration: APS occupies a large piece of land in a city where land is at a premium. How it’s reused could have big impact on housing supply, jobs, energy innovation, and community upliftment.
- For heritage & identity: The station’s chimneys and towers were iconic landmarks. Their preservation or demolition becomes an issue of city memory, industrial heritage, and how a growing city treats its past.
- For sustainability: Turning the site into an energy hub aligns with broader climate/energy transition goals (especially in a city vulnerable to load-shedding and energy supply instability).
5. Outstanding questions / things to watch
- How the heritage case will be resolved: Will the City get permission to alter/demolish major structures, or will preservation dominate?
- What specific development plan will be approved: Will it lean more toward energy/utility use, housing/mixed-use, or hybrid?
- Financing and timeline: Large scale redevelopment will require significant funding, public/private partnerships, and coordination.
- Environmental remediation: Former coal station sites often require soil/groundwater remediation; also asbestos issues.
- Community benefits: Will local residents in Athlone and adjacent areas benefit in terms of jobs, housing, local amenities?
