There is surely no greater sign of the urgent need for reform of the electricity sector than the way Eskom’s electricity tariffs are set. The whole system is far from the way prices should be set – through a competitive market in which firms aim to sell to consumers by offering them better value than others.
The current approach was made clear last week with the revelation that energy regulator Nersa has agreed to a court order that Eskom can collect an extra R54-billion in tariffs over the next few years. That is because of a mistake Nersa made back in January when setting the tariffs Eskom can charge. Eskom was already going to increase prices by almost 13% this year, and now it will be able to increase them by several percentage points more.
The calculations are based on the multi-year price determination (MYPD) method, which includes several elements in setting tariffs over three years. One of those is the “regulatory clearing account” mechanism. This effectively enables backwards-looking adjustments to tariffs if costs turn out to be higher than Nersa had expected they would be when the original tariffs were determined (or, in theory, if revenue is higher than expected). The RCA has the farcical effect of allowing Eskom to charge tomorrow’s customers for yesterday’s costs.
Imagine other companies worked like this! We are in the midst of results season as large companies report on their financial performance for the first half of the year. Many of those reporting show how hard it is to grow revenue in this difficult economy. Companies have really struggled to increase sales, simply because everyone is under pressure, from consumers to businesses. But despite those gloomy top lines, many companies can tell a positive story about how they have been able to control costs by finding more efficient ways to do things, and thereby ensure their businesses are sustainable.
Imagine if instead of this strong pressure to maintain cost discipline, these companies could simply pass last year’s costs onto next year’s customers by upping the prices they pay. Would we be seeing any cost discipline at all? Would companies make difficult decisions about what divisions to close or to cut back on bonuses, or drive more efficient production mechanisms? Of course not.
Nice in theory
Nersa tries to lean against this risk by determining whether costs were “prudently incurred” by Eskom before allowing recovery. That is nice in theory, but Nersa does not have the detailed operational knowledge to determine what is and isn’t prudent, just like I couldn’t tell you about how much costs any other company could save if it faced genuine competition. It is also a political dead end because the costs are already incurred – the only decision is whether they should be paid by the consumer or by the government, and therefore taxpayers.

The RCA model assumes that consumer demand is price inelastic, in other words, that no matter what the price, consumers will keep on paying. So, recovery of last year’s costs is basically being extracted from the same consumers, in theory. But that is changing. Even without a competitive electricity market, consumers do have more choices than ever before – they can turn to rooftop solar, for example. Large companies can and are building their own electricity plants. So, as Eskom prices go up, consumption of Eskom-produced electricity is going to continue to go down.
