Cabinet's 29 July 2026 twin decisions — the Revised Electricity Pricing Policy and the draft Electricity Sector Market Transformation Position Paper — are now the market-structure wildcard every C&I PPA buyer must reprice before SAWEM rules lock in contract economics in Q4 2026.

The Policy Wildcard Has Arrived: Why Every C&I PPA Buyer Needs to Reprice Now

On 29 July 2026, South Africa's Cabinet did something that will reverberate through every boardroom, treasury desk, and property management office that has signed — or is about to sign — a commercial and industrial (C&I) Power Purchase Agreement. Cabinet approved the publication of the Revised Electricity Pricing Policy (REPP) for public comments, and simultaneously approved the publication of the draft Electricity Sector Market Transformation Position Paper for public comments. Taken together, these two documents represent the most consequential restructuring signal the South African electricity sector has received in nearly two decades — and the clock for C&I buyers to act is now running.

For CFOs and property managers who have structured PPA agreements on the assumptions of the 2008 pricing framework, consider this your official repricing notice.

What Cabinet Actually Approved: The Two-Document Reform Package

1. The Revised Electricity Pricing Policy (REPP)

The proposed revision moves to update the 2008 Electricity Pricing Policy in a way that reflects developments in the electricity supply industry, including ongoing market reforms arising from the unbundling of Eskom and the implementation of the Electricity Regulation Amendment Act of 2024. This is not a cosmetic update. According to Cabinet, the revised policy is intended to strengthen the regulatory framework governing electricity prices, tariffs and charges while improving transparency in the way electricity costs are determined. The policy introduces tariff transparency through the unbundling of electricity tariffs across generation, transmission, distribution and retail activities.

In plain English: the bundled tariff structure that has masked true cost components for decades is being dismantled. The proposed policy will separate electricity costs into different parts — generation, transmission, distribution and retail — and Electricity Minister Kgosientsho Ramokgopa said this should give customers a clearer picture of the true cost, with consumers able to see the cost of converting coal into electricity, transmission and administration separately.

The policy introduces a 10-year price forecast, opens the market to competition through bilateral deals and a future wholesale market, and strengthens social protection including a modernised free basic electricity system. It also targets non-payment and illegal connections, removes hidden cross-subsidies from diligent consumers, and expands support for energy-intensive industries via a broader Negotiated Pricing Agreement (NPA) framework.

2. The Draft Electricity Sector Market Transformation Position Paper

Published alongside the Revised EPP, the draft Electricity Sector Market Transformation Position Paper articulates how South Africa intends to move away from its current, largely state-controlled electricity system towards a competitive market, in alignment with the ERAA and the Energy Action Plan. The reform package is moving the country toward a hybrid wholesale market with day-ahead and intra-day trading concepts at its centre.

Critically for PPA buyers: this position paper — published for public comment on 21 August 2026 — introduces SAWEM liability for imbalances between the contracted electricity production of market participants and the actual production or consumption of a generator or load participating in the market. Stakeholders have until 20 September 2026 to provide submissions on the department's position paper. That deadline is effectively now.

SAWEM: The Rules Engine Locking In Contract Economics

At its core, SAWEM marks a decisive break from Eskom's historic vertically integrated monopoly model. Instead of a single buyer and central planner, South Africa is moving towards a competitive, rules-based, multi-market structure with transparent price discovery and shared balance responsibility.

South Africa's electricity market (SAWEM) is set to launch at the end of September 2026 (originally set for April 2026), and five structural blockages threaten to stall the reform further before it moves any power. In early April, it was confirmed by the NTCSA that the April launch had been postponed to the third quarter of 2026 — a delay that produced a surprisingly muted reaction, with private sector players taking the view that they would prefer a delayed launch with all moving parts correctly aligned to a botched rush job.

The South African Wholesale Electricity Market (SAWEM) has reached a key regulatory milestone with the market code formally submitted to NERSA. The submission was confirmed during the latest Operation Vulindlela fourth quarter briefing, with National Treasury officials noting that the code follows extensive stakeholder consultation and technical refinement, and will define the operational and governance rules for participation in SAWEM, including trading arrangements, market participation requirements and settlement processes.

The implication for C&I buyers is severe: power producers participating in SAWEM will face financial penalties for creating any energy imbalances in the power system. If your PPA supplier is not appropriately structured under SAWEM's balance responsibility rules, those penalties flow upstream — and potentially into your escalation clause.

Three Financial Fault Lines Every CFO Must Stress-Test Today

Fault Line 1: Wheeling Cost Transparency Will Break Existing Cost Assumptions

The REPP's unbundling of tariffs across generation, transmission, distribution and retail is not merely an administrative exercise — it is a structural repricing event for wheeling charges. Today, most C&I PPA contracts reference a bundled wheeling cost derived from the existing opaque tariff structure. The policy "strengthens the regulatory framework governing electricity prices, tariffs, and charges, and provides tariff transparency through the unbundling of tariffs across generation, transmission, distribution and retail activities, thus consolidating regulatory arrangements for electricity pricing across the various pricing interfaces."

Once unbundled, each layer will be separately regulated by NERSA. The policy establishes the framework through which these interfaces will be enabled and regulated by NERSA, which has already approved discounted tariffs for two ferrochrome companies and is considering Negotiated Pricing Agreements for other ferroalloy producers and other sectors. What this means in practice: wheeling charges in your PPA may no longer reflect market reality once NERSA begins regulating each layer independently. Contracts that do not include a wheeling cost passthrough mechanism are exposed.

Fault Line 2: PPA Escalation Clauses Need a SAWEM Stress Test

Most C&I PPAs signed between 2022 and 2025 contain escalation clauses pegged to either CPI, a fixed percentage, or a hybrid tied to Eskom tariff movements. South African electricity tariffs have risen at well above inflation for a sustained period, with household prices more than doubling over the past five years as a result of successive Eskom increases. Eskom has locked in further 8.8% increases for both 2026 and 2027.

Under the new market framework, the reference point for "electricity cost" shifts from a single administered Eskom tariff to a market-clearing price formed in SAWEM's day-ahead and intra-day mechanisms. SAWEM introduces a hybrid "net pool" market combining bilateral contracts with centralized dispatch and price formation that fundamentally changes revenue models for IPPs with projects above 10MW. If your escalation clause is pegged to Eskom's Multi-Year Price Determination (MYPD) increases, it may become disconnected from the actual cost of supply as the market matures. CFOs should model at least three scenarios: CPI-only escalation, SAWEM spot price passthrough, and a blended bilateral/market reference basis.

Fault Line 3: BESS Dispatch Revenue Stacks Are Being Repriced in Real Time

For C&I buyers who have incorporated Battery Energy Storage Systems (BESS) into their energy solution — either standalone or co-located with solar — the SAWEM launch fundamentally rewrites the revenue stack. Under the current single-buyer model, BESS value is largely limited to demand charge reduction and PV self-consumption optimisation. Under SAWEM, BESS gains access to ancillary services markets, imbalance arbitrage, and day-ahead price spread capture.

Short-term markets within SAWEM enable demand to be met through dynamic trading, reducing reliance on long-term fixed PPAs. The Day-Ahead Market (DAM) will be a core price discovery mechanism via a blind auction where prices are set by competitive bids. This means BESS dispatch decisions will increasingly be driven by wholesale price signals, not just on-site consumption profiles. Any BESS PPA or lease agreement that does not contractually account for the right to dispatch into SAWEM markets — or that does not share ancillary services revenue with the C&I offtaker — is a contract that leaves money on the table.

The policy explicitly targets grid-connected solar and partial-defection users under an "anti-free-riding" principle, shifting tariff structures from volumetric consumption to high, unavoidable fixed monthly connection fees. This is the sleeper clause in the Position Paper that most PPA buyers have missed: fixed grid charges will erode the net savings of solar-only installations and make BESS-augmented systems relatively more attractive from a payback perspective.

The Full Customer Choice of Supplier Shift: A Structural Opportunity

In a parallel reform initiative, Cabinet approved the publication of the draft Electricity Sector Market Transformation Position Paper, which outlines a framework to guide South Africa's transition from a predominantly state-controlled electricity system to a more competitive electricity market. Central to this framework is the concept of full customer choice of supplier — the ability for eligible customers (starting with large industrial users and eventually including commercial buyers) to source electricity directly from any licensed generator or trader without being restricted to their distribution utility.

The proposed reforms seek to improve energy security and reliability by reducing reliance on a single electricity supplier and enabling greater participation in electricity generation and trading, while also attracting investment in electricity generation, transmission and distribution infrastructure, supporting job creation and economic growth, and reducing electricity costs over the long term.

For property managers with multi-tenant commercial buildings, this opens a significant structuring opportunity: aggregated tenant loads could qualify for direct market access under SAWEM's eligible customer threshold, enabling bulk procurement at wholesale rates rather than retail municipal tariffs.

Practical Recommendations for Q4 2026

Audit your PPA escalation clauses immediately. Identify whether your escalation reference index will remain valid under a market-based pricing regime. Flag any clauses tied solely to Eskom MYPD determinations for renegotiation before SAWEM locks in contract economics.
Map your wheeling cost exposure. Request a line-item breakdown of wheeling charges from your PPA supplier. Once NERSA begins regulating unbundled tariff layers independently, bundled wheeling costs will be repriced — know your exposure before the regulator does it for you.
Submit on the Position Paper before 20 September 2026. The reforms signal continued momentum towards a competitive electricity market, and stakeholders should closely monitor developments and participate in the consultation process, particularly on tariff structures, regulatory arrangements and the implementation of cost-reflective pricing. Your CFO's voice matters in shaping the final rules.
Stress-test your BESS dispatch contracts. Ensure any BESS agreement explicitly addresses SAWEM market participation rights, balance responsibility allocation, ancillary services revenue sharing, and fixed grid charge exposure under the anti-free-riding tariff principle.
Model the 10-year price forecast horizon. The revision of the Electricity Pricing Policy is explicitly intended to ease the burden on the most fragile households while offering a clearer price trajectory to private investors financing new generation capacity. Use the emerging 10-year price forecast framework to build more robust IRR and payback models for Q4 2026 capex decisions.
Assess eligibility for Negotiated Pricing Agreements. The policy expands support for energy-intensive industries via a broader Negotiated Pricing Agreement framework. If your portfolio includes high-consumption anchor tenants or industrial facilities, an NPA may now offer a lower-cost baseline than a standard C&I PPA.

The Bottom Line for C&I Buyers

The proposed Electricity Sector Market Transformation Position Paper represents the most consequential restructuring of South Africa's energy landscape in decades. The 29 July 2026 Cabinet decisions do not change today's electricity bill — but they change the architecture within which tomorrow's electricity costs will be determined, regulated, and recovered. Every C&I PPA signed or renewed in Q4 2026 without accounting for SAWEM market rules, unbundled wheeling transparency, and BESS dispatch revenue stacks is a contract built on a foundation that the market is actively dissolving.

The public comment window closes. SAWEM goes live. And the contract economics that felt safe six months ago may look very different by the time your next energy audit lands on the CFO's desk.
