Unit 2 of Rooppur NPP achieves concrete milestone

A concrete work milestone has been reached at the Rooppur nuclear power plant’s (NPP’s) Unit 2 construction project. This week saw the completion of concrete works for the Unit 2 of Rooppur NPP (Bangladesh) turbine hall foundation slab, said Rosatom. The slab structure contains 3782 t of rebar and 23 550 m3 of concrete. Sergey […]

Global shift to renewable power growing steadily, report shows

Progress in renewables remains concentrated in the power sector, while far less growth has occurred in heating, cooling and transport. The year 2018 saw a relatively stable market for renewable energy technologies. A total of 181 GW of renewable power was added, a consistent pace compared to 2017, and the number of countries integrating high […]

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 […]

Understanding the basics of power measurement theory

Electrical power applications are changing rapidly. LED lighting is replacing incandescent lamps, variable speed motor drives replace directly coupled electric motors, and photovoltaic (PV) installations and wind turbines generate additional electrical power. This means the load on the electric network is changing. More harmonics and more risk of unbalance. This so called “bad” power costs […]

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 […]

Integrating renewable energy sources into smart grids – Part one

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 […]

Onsite power for remote mining locations

The need for a secure, efficient power supply is as important to mining operations as the equipment used by the mine to keep production up and running, sometimes on a continuous basis. Many remote mine sites are located at a great distance from the nearest power grid, resulting in the need to establish reliable off-the-grid […]
