The National Energy Regulator of South Africa (NERSA) has approved an 8.76% electricity price hike in April this year, followed by an 8.83% increase in April 2027.

The move is a redetermination of Eskom’s price increases for the next two years, which were initially set at 5.36% for 2026/27 and a further increase of 6.19% for the 2027/28 financial year.

“The redetermination follows a High Court judgment [in December], which remitted NERSA’s decision on Eskom’s Generation RAB [Regulatory Asset Base] for 2025/26, 2026/27 and 2027/28 for redetermination.

“The redetermination was conducted using the approved MYPD4 [Multi-Year Price Determination] Methodology, following a public consultation process in line with the court judgement.

“This process entailed NERSA undertaking a detailed, component-by-component recalculation of Eskom’s Generation RAB, using the same information originally submitted by Eskom in its MYPD6 application and applying the approved methodology strictly,” a NERSA statement read.

The total additional revenue for Eskom will be implemented in phases.

“The phased approach limits additional price impacts to single digit increases in 2026/27 and 2027/28, and avoids any retrospective adjustment for 2025/26, in line with the court judgment. It further reduces tariff volatility and demand erosion risk and balances Eskom’s financial sustainability with customer affordability. No retrospective tariff increases were applied.

“The re-determination is consistent with the statutory tariff principles, which require tariffs that enable an efficient licensee to recover the full cost of licensed activities, including a reasonable return.

“NERSA’s adopted WACC [Weighted Average Cost of Capital] and phased recovery reflect an approach that ensures Eskom receives a reasonable, cost-reflective return while mitigating immediate tariff shocks, limiting demand erosion, and maintaining tariff stability. NERSA remains committed to transparent, fair, and independent regulation in the public interest,” the statement read.
