Growthpoint enters 195 GWh/y renewable energy PPA with Etana Energy

JSE-listed real estate investment trust Growthpoint Properties has entered into a power purchase agreement (PPA) with electricity trader Etana Energy for 195 GWh/y of renewable energy, which represents 32% of its total current yearly electricity consumption, which was 612 GWh in its 2023 financial year. The company signed the PPA in November 2023 to wheel electricity to its commercial property buildings in several jurisdictions across the country. Further, the generation profile will be relatively flat over a 24-hour period owing to it consisting mainly of wind power and a smaller hydropower generation component.

IPPO ‘engaging’ with Eskom on implications of new curtailment rules for current renewables …

The Independent Power Producer Office (IPPO) reports that it is engaging with Eskom on its newly released curtailment addendum to the latest Generation Connection Capacity Assessment (GCCA 2025) – through the addendum 3 470 MW of additional connection capacity for wind generators has been unlocked in two grid-constrained provinces. Prior to the publication of the addendum, the GCCA 2025 indicated there to be no remaining grid capacity available in the Eastern, Northern and Western Cape provinces. But the addendum indicates that, by accepting a “reasonable share of no more than 10% of curtailment”, 2 680 MW of capacity is available in the Western Cape and 790 MW in the Eastern Cape.

Night loadshedding escalates to Stage 3 

Loadshedding will jump to Stage 3 at 16:00 Monday after a delay in the return to service of two generating units. “Over the past 24 hours, five generation units were taken offline for repairs. Additionally, the return to service of two generating units that were on planned maintenance was delayed due to an opportunity to perform preventative maintenance. These factors have contributed to the shortage of available capacity necessitating the implementation of Stage 3 loadshedding from 16:00 today until 05:00 on Tuesday,” Eskom said.  “Thereafter, loadshedding will be reduced to Stage 2 until 16:00 on Tuesday. This pattern of Stage 2 loadshedding from 05:00 until 16:00 and Stage 3 loadshedding from 16:00 until 05:00 will be repeated daily until further notice.”

NNR approves the separation of the operating timelines of Koeberg’s nuclear reactors

The National Nuclear Regulator (NNR) has announced that it has approved the request of national electricity utility Eskom to separate the operational timelines for the two reactors of the Koeberg nuclear power plant (NPP). Koeberg, located on South Africa’s west coast, near Cape Town, is the country’s (and still Africa’s) only operating NPP. (The continent’s second NPP, El Dabaa in Egypt, is still under construction.) The two reactors were designed Unit 1 and Unit 2. “After completing its safety assessment, the NNR confirmed that the approval of the separation of the units will not impact the safety of the Koeberg nuclear power stations,” reported the regulator, in its press release.

Firm hails efficiency plan’s stance on electric motors

Plan to apply the Minimum Energy Performance Standards (MEPS) for low-voltage electric motors in South Africa have been hailed by solutions provider WEG Africa as an exciting step toward energy efficiency and a lower carbon future for the industry. The Department of Trade, Industry and Competition recently announced its intention to put a stop to imports of low-efficiency motors – in the power rating range from 0.75 kW to 375 kW – in favour of motors in the efficiency class of IE3 and above.

Energy efficient solutions for loadshedding

South Africa’s electricity problems have left the country without power for many hours a day, causing grave difficulties for businesses and households, notes power generation and electromechanical power transmission product supplier Vert Energy. “The inability of the country’s primary electricity supplier to meet demand has called for the private sector to step up and provide solutions that help keep businesses, education facilities, hospitals and more running, in the event of power outages and loadshedding,” explains Vert Energy sales and marketing director Ryan Robertson.
