Brought to you by SA Legal Academy: The National Energy Regulator of South Africa has issued a discussion document for public comment regarding the revised Eskom retail tariff structural adjustment for the 2026/27 financial year.

In terms of the Electricity Regulation Act, No. 4 of 2006, the National Energy Regulator of South Africa (NERSA) has gazetted a notice calling for stakeholder input by 2 March 2026 on the Eskom retail tariff structural adjustment (ERTSA) discussion document. This process follows three recent High Court judgments that directly impact the 2026/27 ERTSA determination.

A specific ruling delivered on 21 December 2025 in the matter of Eskom Holdings Soc Ltd v NERSA set aside Eskom’s allowable revenue for the 2026/27 and 2027/28 financial years. Consequently, NERSA has redetermined the figures, which informed a revised 2026/27 ERTSA proposal submitted by Eskom on 13 February 2026.

The discussion document invites comments on several key areas, including:

  • The structural adjustments necessitated by the redetermined allowable revenue;
  • The impact of the 21 December 2025 High Court judgment on tariff setting; and
  • Specific questions regarding the revised 2026/27 ERTSA received on 13 February 2026.

What this means for you, your business, or your clients

  • For yourself: Monitor the redetermination process to ensure professional advice regarding energy pricing and regulatory compliance remains aligned with the latest court-mandated adjustments.
  • For your business: Evaluate the potential impact of the revised retail tariff structures on long-term energy budget forecasts for the 2026/27 financial year.
  • For your clients: Assist clients in drafting and submitting technical comments to NERSA by the 2 March 2026 deadline to ensure their interests are represented in the final structural adjustment determination.
