Coal-mill optimisation in coal-fired power stations aids flexibility

Many of the existing pulverised coal-fired (PCF) power stations are operated at a fixed steady load (i.e. baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal […]

How modern gas turbines achieve excellent environmental performance at high load

This article explains how the gas turbines used at the Dedisa and Avon peaking power plants – which were highlighted in the June 2016 edition of Energize (“Privately owned peaking power station nears completion”) – achieve their environmental performance with lower NOx emissions even when operating at peak load. Dedisa and Avon peaking power stations […]

Power usage effectiveness in data centre management

Power usage effectiveness (PUE) is growing in popularity as an efficiency metric by the data centre market. While PUE is a tool to deploy an approach, or develop an implementation within a data centre, the measurement of PUE and its accuracy could have an increasingly negative impact. Where the energy manager of a data centre […]

Starting the journey towards energy-efficiency

  According to the International Energy Agency, many companies are using up to 100% more energy than they would if they were best practice, energy efficient businesses. After the power crisis of 2007 and 2008, and the steep rises in electricity tariffs that followed, South African industrial groups moved quickly to reduce their energy consumption. […]
