Integrating renewable energy sources into smart grids – Part three

There is global momentum to diversify electricity generation sources for economic, environmental and security reasons. Distributed generation (DG) enables more companies to enter the electricity market stimulating competition, encourages the development of renewable energy (RE) and limits the impact of events such as cyber-attacks. However, conventional electricity distribution networks are poorly matched to the needs […]

The gas turbines/battery hybrid: Ideal partner for wind and solar

The increasing amount of renewable energy in networks has led to challenging situations which require flexible balancing generation plant that can respond rapidly to changes in generation and demand. Open-cycle gas turbines (OCGTs) have been used successfully in this function, but the growth of renewable energy (RE) in some networks has outstripped the ability of […]

Choice of PV backsheet material affects module life

DuPont Photovoltaic and Advanced Materials’ (DuPont’s) 2019 Global Field Reliability Study shows that the choice of backsheet material used on PV modules can result in significant degradation and negatively impact solar module performance. The report lays out failures with PET, polyamide and PVDF backsheets and issues with glass-on-glass modules. The report also highlights trends in […]

Tackling energy shortage challenges in South Africa

Climate change continues to be one of the most important subjects of conversation around the globe. Whether it is among friends, work colleagues or around political tables, it is a hot topic that needs urgent assessing. At Sustainability Week 2019, this issue will be tackled head on through the Sustainable Energy Seminar on Tuesday, 25 […]

The future of hydrogen: Seizing today’s opportunities

The time is right to tap into hydrogen’s potential to play a key role in a clean, secure and affordable energy future. At the request of the government of Japan under its G20 presidency, the International Energy Agency (IEA) has produced this landmark report to analyse the current state of play for hydrogen and to […]

Africa’s energy landscape transitions to base load-capable renewables

The advent of renewables, new storage technologies present Africa’s utilities with an opportunity to increase capacity and efficiency while re-kindling their appeal to investors.  There has been a clear and rapid evolution in Africa’s energy and energy infrastructure landscape over the last decade. While much of this new technology has challenged the traditional dominance and […]

Extending the investment in renewable energy in SA

Reatile Renewables has taken up a 20% shareholding in Juwi Renewable Energies’ EPC company, which is currently building three projects for Round 4 of South Africa’s renewable energy independent power producers procurement programme (REIPPPP), totalling 250 MW of grid-connected solar PV. Reatile formally entered into the agreement, with the signing of the papers by Simphiwe […]
