Progress on global energy goals slow, but strong gains in some countries show promise

The world is not on track to meet the global energy targets for 2030 set as part of the Sustainable Development Goals (SDG), but real progress is being made in certain areas – particularly expansion of access to electricity in least developed countries, and industrial energy efficiency, according to a new report from five international […]

Why is energy efficiency still on the to-do list?

Energy efficiency, which has been defined as “the best and cheapest way to reduce CO2 emissions and use the least amount of electricity to achieve a desired result” and is often viewed as an obvious cost-saving option in an industrial or commercial operation, is frequently not implemented in South Africa. The National Energy Act of […]

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 […]
