The National Energy Regulator of South Africa v Borbet SA (Pty) Ltd

NERSA approved a 1.4% additional electricity tariff increase for Eskom for the 2013/2014 financial year, over and above an already approved 8% increase, based on Eskom's Regulatory Clearing Account (RCA) application. Eskom had applied for approximately R22 billion in adjustments due to revenue shortfalls and increased costs including OCGT usage, coal costs, IPP costs, and lower electricity sales volumes. The first to sixth respondents (Borbet and others), who were electricity consumers and business representatives in the Nelson Mandela Bay area, challenged NERSA's decision in the High Court. They argued primarily that NERSA had failed to comply with the Multi-Year Price Determination Methodology (MYPDM3), specifically that Eskom had not submitted quarterly financial reports as required and that the RCA process was not initiated during the 2013/2014 tariff year. The High Court (Pretorius J) reviewed and set aside NERSA's decision, finding it irrational and procedurally unfair for failing to follow the MYPDM3. NERSA and Eskom appealed.

• Whether NERSA's adjudication of Eskom's tariff adjustment application constituted administrative action reviewable under PAJA
• Whether courts reviewing such decisions would offend the doctrine of separation of powers
• Whether NERSA's decision was rational and lawful despite Eskom's failure to submit quarterly financial reports as required by the MYPDM3
• Whether NERSA's decision-making process was procedurally fair
• The proper interpretation and application of the MYPDM3, particularly the RCA provisions
• The extent of judicial deference owed to specialized administrative bodies like NERSA

The appeal was upheld with costs including costs of two counsel. The High Court order reviewing and setting aside NERSA's decision was replaced with an order dismissing the application with costs including costs of two counsel. The 1.4% tariff increase approved by NERSA was thus confirmed as lawful.

NERSA's adjudication of tariff adjustment applications by Eskom constitutes administrative action subject to judicial review under PAJA, not policy-making immune from scrutiny. A licensee's failure to comply with procedural requirements of the pricing methodology (such as submitting quarterly reports) does not automatically preclude the regulator from considering a tariff adjustment application, as such failures may warrant sanctions but do not vitiate the entire regulatory process where the regulator has properly considered the non-compliance. Courts must exercise appropriate deference to specialized administrative bodies like NERSA when reviewing decisions involving complex policy balancing and technical expertise, while still ensuring decisions are rational, procedurally fair, and legally authorized. The MYPDM3 regulatory framework must be interpreted purposively to enable NERSA to balance Eskom's financial sustainability with consumer protection and broader economic interests.

The Court observed that state-owned enterprises should resist the impulse to immediately resist constitutionally permissible judicial scrutiny and should default to making information publicly available subject to justifiable redaction, as they are ultimately owned by the nation through the State. The Court noted that Eskom and NERSA should have adopted a more transparent attitude earlier in the litigation. The Court also commented that South African taxpayers and electricity consumers are "exhausted by the constant historical failures by Eskom" and emphasized that what is required is "optimum efficiency and accountability" from Eskom, with NERSA and government tasked to ensure that result. The Court acknowledged the reality of Eskom's historical inefficiencies and lack of foresight, and noted that prospective remedies are matters to be addressed by NERSA with government oversight beyond the scope of adjudicating the specific RCA application.

This case clarifies important principles regarding judicial review of decisions by specialist regulatory bodies in South Africa. It establishes that: (1) regulatory decisions by bodies like NERSA, even when applying policy, constitute administrative action reviewable under PAJA; (2) procedural non-compliance with methodology does not automatically invalidate regulatory decisions where the regulator has properly considered the non-compliance and the decision remains rational; (3) courts must exercise appropriate deference to specialized administrative bodies dealing with complex, polycentric policy matters while still ensuring decisions are rational and procedurally fair; (4) the regulatory framework for electricity tariffs balances licensee sustainability with consumer protection and economic impact; and (5) failure to comply with license conditions does not operate as a guillotine preventing regulatory action but may warrant sanctions. The case is significant for administrative law, energy regulation, and understanding the limits of judicial intervention in specialized regulatory decision-making.
