In the weeds
SOUTH AFRICA HAS GONE some way in starting to reform its electricity industry, which has been failing the country visibly for nearly two decades. As these changes are published, consulted and implemented, however, it becomes increasingly apparent that South Africa is really only at the end of the beginning.
It is also becoming clearer that regulatory and legislative reform will have to continue well into the future, probably endlessly. Ongoing revisions are required not only to catch up with technology and market developments that have made the current set of reforms necessary yet insu cient, but also to keep pace with the changes that will arise as the global energy sector undergoes a once-in-a-generation transition.
At a high level, these changes are straightforward to describe: the electricity industry is decentralising, decarbonising, democratising, digitising, and diusing.
Put dierently, technologies such as solar and wind, which, have emerged as the cheapest generators of new electrons, don’t rely on the economies of scale that made coal and nuclear the previous technologies of choice for extending electricity’s bene ts. These more incremental solutions open space for democratisation, as consumers become producers.
Being weather- rather than fuel-dependent also means that they can be deployed at any point in the network, which, together with the democratisation trend, means the system will progressively decentralise.
They also have environmental attributes that governments are seeking to promote, and citizens are increasingly demanding, including decarbonisation. And as the world seeks to accelerate efforts to tackle climate change, electrification of almost everything makes increasing sense, as solutions are found to diuse more aordable wind and solar into other carbon-heavy energy sectors. In other words, direct electrification (think electric cars) and indirect electri cation (think green hydrogen) will increasingly penetrate other energy sectors such as mobility, heating and industrial processing.
This democratisation, diusion and decentralisation are being enabled by digital solutions that are providing system operators, producers and consumers with the visibility and exibility that could have only been dreamed of a few decades ago.
Nevertheless, when this easy narrative collides with a reality comprising hard-wired legacy systems and skillsets, multidecade assets, incumbent self-interest and local and national politics, complexity not only abounds – it multiplies.
Such complexity cannot be dealt with simply through truisms, even though these are important to move the industry in the right direction. Instead, it is dealt with through grappling with the technical, financial and social risks and opportunities, while agreeing on legislative and regulatory guardrails that can be translated into workable operating procedures and standards. It’s about getting deeply into the weeds, with the overarching objective of nding a way through and out, rather than becoming lost in them.
A case in point is the work that recently started on the market code for a future multimarket electricity architecture presupposed by recent legislative developments. It is precisely such complex and detailed work that practitioners in the electricity space need to now undertake if this transition is to deliver the bene ts many hope and believe it can.
