State-owned electricity utility Eskom’s decision to approach the courts for urgent relief in the form of a reversal of the Energy Regulator’s controversial March 7 decision to offset a government equity injection of R69-billion through a lowering of the utility’s return on assets could result in material increases in electricity tariffs in the coming two years. Eskom announced on October 11 that it had applied for urgent interim relief against the Energy Regulator’s fourth multiyear price determination (MYPD4), which it would also take on legal review on a non-urgent basis.
