Cape Town metropolitan mayor Geordin Hill-Lewis has highlighted the city’s programme to generate power locally and free the metro from loadshedding imposed by national electricity utility Eskom.

Hill-Lewis was addressing the Energy Indaba conference, which was held in the city last month

“Loadshedding and rolling blackouts are the number one handbrake on the South African economy right now,” he pointed out. A manufacturing industry could not be developed under loadshedding conditions. Services could get by, for example, by installing solar power systems. But that was not an option for heavy industry. And economic growth was essential to eliminate the serious problem of poverty.

Eskom and the national government were on the right path, he said, but they still had a long way to go, and they still had serious policy disagreements at the highest levels. He pointed out that the country had had loadshedding for 15 years and that it was actually getting worse. “We cannot become used to failure,” he warned.

He noted that Cape Town had a head start over the country’s other cities in that it benefited from the Steenbras hydro pumped- storage power station. Commissioned in 1980, the power station was owned and operated by the City of Cape Town and had been thoroughly maintained and was in excellent condition. Steenbras always saved Cape Town from at least one loadshedding stage, and often from two stages.

But the city council also had a 50-month programme, which was publicly available, to give Cape Town total immunity from loadshedding. This programme was already budgeted for.

This was complemented by a number of policy changes by the city. Thus, since September, the city has had a policy to buy surplus solar-generated electricity from commercial entities. “We’re getting that payment system up and running,” he reported. The aim was to encourage commercial businesses to cover their extensive roofs with solar panels. Once the system had been proven with commercial property owners, it would be rolled out for private property owners.

Cape Town was also the only city in the country that had so far implemented a wheeling power pilot project with eight participants. Wheeling power meant that these eight entities sold power they had generated to third parties, using the city’s distribution system, for which they paid a small fee.

The city had concluded the first round of the bidding process for independent power producers for Cape Town. This was a small round, for a total capacity of 200 MW to 300 MW. But this was not for ‘despatchable’ power – that is, there was no requirement for storage. Solar power produced most electricity at midday, but peak demand was in the morning and evening.

So, in January, the city would issue a tender for a “very significant” capacity of dispatchable power – that is, it would include energy storage. Hill-Lewis stressed that the tender would be technology-agnostic and that there would be no capacity cap. All that would be required was that the price of the electricity produced would match, or beat, Eskom’s price.

Cape Town was also doing “fairly detailed” investigations into energy storage systems, he noted. Batteries were expensive, but the costs were coming down. The alternative was to expand the Steenbras power station. The decision would be taken in due course.

He also highlighted various administrative hurdles, imposed by the national government, that the metro had had to overcome or even disregard (because the city had concluded, after due consideration, that they were not applicable), to implement its local power generation programmes. He also noted that there was confusion in national government about what administrative procedures were relevant to Cape Town’s programmes and which weren’t.

The mayor further stressed the importance of maintaining the city’s infrastructure. He cited the National Treasury’s expectation that each municipality would spend 8% of its budget on infrastructural repair and maintenance. Cape Town was at 7.4%, although this was much better than other cities – Johannesburg was spending just 2%, for example.
