Sectional-title estate residents locked in a dispute with developer Balwin Properties over private electricity resale and smart-geyser management have hit a major regulatory wall as the National Energy Regulator of South Africa (Nersa) has admitted it lacks the statutory power to enforce its reseller guidelines.
The revelation comes amid mounting tension between homeowners in Helderberg lifestyle estates and Balwin Properties over the developer’s private energy partnership with SolarAfrica and Plentify.
At the centre of the dispute are claims by locals that private resellers are manipulating household appliances and inflating energy costs under the guise of green compliance.
A local geyser expert, who asked not to be named, monitored a Balwin estate’s utility framework and claims that centralised solar PV systems are dumping excess daytime energy into private geysers without resident consent.
According to the expert, data logs show geyser temperatures being driven up to 75 °C during daytime hours to clear solar capacity, resulting in severe thermal losses and element switching.
“The homeowner is supposed to be the beneficiary of green energy under Sans 10400-XA regulations,” the expert said.
Instead, daytime energy is billed through the meter while consumers are denied access to their geysers, prohibited from installing timers and charged unit rates higher than the City of Cape Town tariffs. The promoted 10% rebate is a bluff when base rates are already inflated.
Residents further argue that Nersa guidelines strictly prohibit resellers from making a profit on electricity tariffs passed to end-users or charging rates higher than the local municipality.
Balwin Properties strongly rejected the allegations, stating that its central solar PV and integrated geyser control systems are designed specifically to lower electricity costs and achieve IFC EDGE Advanced green certification.
Responding to the claims, Balwin confirmed that residents receive a guaranteed minimum 10% saving across their entire consumption relative to published municipal tariffs – not just on the solar portion.
Default setting
“The claim that residents’ geysers are forced to 75 °C is incorrect,” Balwin stated, explaining that its newly integrated Plentify HotBot smart controllers default to
55 °C, with user-adjustable ranges between 45 °C and 65 °C. Factory-installed thermostats remain capped at 65 °C as a safety limit.
“The system never causes the geyser to consume more energy than required to maintain the chosen temperature. The use of available solar energy simply displaces electricity that would otherwise have been drawn from the grid,” the developer added.

Balwin cited independent performance verification by the SANAS-accredited University of Cape Town (UCT) Measurement and Verification Inspection Body, which demonstrated an 18% overall reduction in geyser energy consumption and a 70% drop in peak-period load across tested units.
Regarding physical access and controls, Balwin noted that service-room geyser placement is standard in sectional-title developments for safety and common infrastructure maintenance. The developer maintained that residents retain the ability to adjust temperatures via the Plentify Home App and can manually isolate geysers at their distribution boards.
However, the legal foundation relied upon by aggrieved homeowners has been thrown into doubt following official clarification from Nersa.
Responding to DistrictMail & Helderberg Gazette’s enquiries on whether remote appliance manipulation and tariff markups violate consumer protection rules, Nersa’s head of communication Charles Hlebela, confirmed that the regulator’s authority over private resellers is severely constrained.
“The prevailing regulatory framework does not comprehensively regulate or prescribe the activities undertaken by electricity resellers,” Hlebela said.
“The principal statutory requirement is that resellers are required to be registered with the Energy Regulator. Save for this registration obligation, the act and associated regulations are silent as to the detailed conduct and operational parameters applicable to resellers.”
Crucially, Hlebela revealed that Nersa’s widely cited reseller rules offer no direct legal protection.
While Nersa has published guidelines pertaining to the conduct of resellers, such guidelines are advisory in nature and do not possess the force of law.
Nersa confirmed that unregistered resellers fall outside its direct regulatory jurisdiction. Consequently, residents alleging contract breaches, forced appliance settings or tariff disputes cannot rely on Nersa for enforcement or intervention.
Instead, Nersa advised affected homeowners that their only immediate recourse lies with either instituting civil court proceedings for breach of contract or lodging formal complaints under the Consumer Protection Act (CPA).
