It’s costing more these days to build and run solar farms and wind turbines, but they’re still cheaper than power plants that rely on fossil fuels. The costs of renewable plants are rising after years of declines due to soaring prices for materials, shipping and labour, according to a BloombergNEF report. But costs for coal and natural gas-fired plants are increasing even faster as global energy prices surge following Russia’s invasion of Ukraine. As a result, new onshore wind and solar projects cost roughly 40% less than coal or gas plants built from scratch—and the gap is widening.
Research company ResearchAndMarkets’ 2022 report shows that the global battery energy storage system (BESS) market is expected to grow from $4.4-billion in 2022 to $15.1-billion by 2027, at a compound annual growth rate (CAGR) of 27.9%. The growth of this market is mainly driven by the increasing demand for grid energy storage systems owing to ongoing grid modernisation, growing penetration of lithium-ion batteries in the renewable energy sector, and the rising trend of low-carbon and less fossil fuel-based economies and the ongoing renewable energy revolution.
Experienced engineers are crucial in such a critical and technically-minded sector as engineering, and it is consequently not surprising that the industry players place a premium on the employment of those who have the years under their belts, says engineering firm Zimile Consulting Engineers CEO Shawn Gama.
Industry body the South African Energy Storage Association chairperson Mikhail Nikomarov emphasises the importance of a decentralised power system and the benefits it can provide, and how this can be supported using battery energy storage systems (BESS) in the local market. “Energy storage through batteries doesn’t have to be centralised like other forms of storage such as pumped storage hydropower.”
Earlier this year, industrial hose specialist Truco announced it had started manufacturing stainless steel braided hose at its Chamdor campus in Johannesburg, Gauteng. Initial capabilities are for hose assemblies from 6 mm to 25 cm in diameter.
Energy technology company General Electric (GE) is tripling manufacturing capacity for its solar and battery energy storage power electronics systems by the end of this year to 9 GW/y, linked to strong growth in backlogs over the past few months and a robust demand outlook. The systems are manufactured at GE’s newly launched Renewable Hybrids factory in Vallam, near Chennai, India.
Industry body Consulting Engineers South Africa (Cesa) is challenging the decision by the South African National Roads Agency Limited (Sanral) board to cancel critical infrastructure tenders worth R17.5-billion on the basis that the adjudication process was flawed owing to the involvement of design engineers in the tender adjudication process.
The Covid-19 pandemic has led to increased retrenchments and job losses in the consulting engineering industry, which, in turn, has led to a skills drain in the sector, temporary works consultant Waco Engineering Services MD Otto Botha says.
Growthpoint Properties, South Africa’s largest real estate investment trust, said its running out of diesel to operate generators at some of its buildings as the country grapples with the worst electricity shortage since 2019. In a letter to customers at one of its sites in Johannesburg the company said it suppliers are struggling to keep up as Eskom Holdings, the national power utility, cuts as much as 6 000 megawatts from the national grid after a pay strike disrupted operations.
Power utility Eskom on Thursday said it would again implement Stage 6 load-shedding, from 14:00 until midnight, as the unlawful strike by employees continues. Stage 4 load-shedding will be implemented from 00:00 to 05:00 on Friday. From 05:00 until 00:00 on Friday, load-shedding will be implemented at Stage 6.
