Flexibility from the Carolinas to South Africa

Among the biggest challenges for flexible operations is to determine how long a power plant can run at a lower level without incurring damage or increasing costs. The Electric Power Research Institute (EPRI) is helping Duke Energy and Eskom to fine-tune power plants for lower loads and other flexible modes.  Duke Energy, based in Charlotte, […]

Implementing LNG with Coega as the hub

Dr Ayanda Vilakazi, the Coega Development Corporation’s (CDC’s) head of marketing and communications, says the CDC welcomes the minister of mineral resources and energy’s intention to explore more economical options to bring liquefied natural gas (LNG) onto the South African market. In 2008, the Department of Energy identified the Coega Special Economic Zone (SEZ) as […]

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 […]
