Eskom supports solar water heaters as they reduce peak demand pressure on the national grid.
Interest: Managing R400bn+ debt restructuring with government support; maintaining grid stability during the unbundling transition; preserving technical and ins…
Concern: Unbundling of the distribution arm (EDI) could fragment operational coherence and create regulatory gaps; transmission entity capitalisation requires…
Engagement path: Credible debt restructuring plan with government guarantees; adequate transition period for unbundling with clear milestones; grid investment ring-fen…
Treasury supports solar water heater rollout only through targeted subsidies with clear cost-benefit analysis, not open-ended programmes.
Interest: Fiscal consolidation with public debt stabilising below 75% of GDP; structural reforms that improve revenue without expanding contingent liabilities;…
Concern: Unfunded mandates in energy transition (JETP co-financing); Eskom's R400bn+ debt and how restructuring socialises costs; reform proposals that create…

Solar water heaters (SWH) reduce household electricity consumption by 30–40% by substituting electric geysers — one of the largest residential electricity loads. The DMRE's Solar Water Heater Programme (SWHP) has been running in various forms since 2008, targeting 1 million installations but achieving far fewer due to supply chain, installation quality, and financing constraints. The updated programme model uses an ESCO (Energy Services Company) delivery mechanism with a monthly service fee replacing upfront capital cost. Municipalities and utilities procure installations via competitive tender; Eskom rebates provide fiscal support. The programme targets low-income households (subsidised) and middle-income households (financed). SABS accreditation standards for imported Chinese SWH units address quality failures that plagued earlier rounds. Potential to reduce residential peak demand by 400–600 MW at scale.

OECD SA Survey (2020, 2025). The 2020 survey dedicated a section to water management; agricultural water prices flagged as too low.
A subsidised geyser replacement programme is among the cheapest demand-side interventions available — R3,000 per household vs. R30,000 per kW of new generation. — Eskom DSM Evaluation 2023
The Solar Water Heater Programme targets 1 million installations using an ESCO delivery model to eliminate the upfront capital barrier that constrained prior rounds. Electric geysers account for 35–40% of residential electricity consumption and 400–600 MW of peak demand; systematic substitution is one of the most cost-effective demand-side interventions available. The Eskom rebate programme and DMRE subsidies for low-income households provide the fiscal foundation; the ESCO model shifts procurement, installation, and maintenance risk from households to service companies. SABS accreditation standards address the quality failures of imported units that undermined earlier rounds.
Publish revised SWHP programme guidelines incorporating the ESCO service model: competitive tendering for ESCO contracts, SABS accreditation standards, installation warranty requirements, and performance-based payment linked to measured energy savings
Procure 10 regional ESCO contracts via competitive tender (CIDB-registered contractors); ESCO contracts cover installation, maintenance, and performance monitoring for 5-year periods
Launch low-income subsidy stream: DMRE subsidy of R8,000–R12,000 per unit for households earning below R3,500/month in partnership with municipalities and Social Housing Institutions; integrate with the Housing Subsidy System

Implement Eskom rebate programme for middle-income households via the MyEskom Customer Portal; target 200,000 applications per year at R5,000 per unit average
Establish a national SWH performance monitoring system tracking installations, measured energy savings, warranty claims, and ESCO performance; publish annual report to Portfolio Committee
Review and tighten SABS accreditation standards: mandatory 5-year performance warranty, corrosion resistance testing, and thermal performance certification aligned with ISO 9459
5-year programme 2025–2030: 200,000 installations/year target; 1 million total by 2030; 400–600 MW peak demand reduction
Total programme cost over 5 years: R8–12 billion (DMRE subsidies R4B + Eskom rebates R3B + ESCO operational costs R1–2B). Cost per MWh saved: R0.40–0.60/kWh over the 15-year SWH lifetime — one of the lowest-cost demand-side resources available.
No new primary legislation required. The SWHP operates under DMRE programme authority and Eskom tariff licence conditions. National Building Regulations (SANS 204) already includes solar water heater provisions for new buildings.
Strong consensus on the SWHP concept; previous rounds succeeded technically but failed on scale and quality. ANC, DA, and coalition partners all support. Eskom supports peak demand reduction. The ESCO model reduces programme administration burden on DMRE. Installation quality and maintenance risks are the primary implementation challenges, not political opposition.
Morocco's national SWH programme achieved 700,000 installations in 10 years using a similar ESCO delivery model — directly applicable. Tunisia's PROSOL programme (200,000 installations, 2005–2015) used commercial bank financing with government interest rate subsidies. Brazil's Programa Solar Brasil demonstrates integration with social housing at scale.
