Adding Stability and Reliability to the Western Australian Grid
Large distances are something you get used to if you live in Australia. Perth, on the west coast, is about 2,500 miles away from Brisbane on the east coast. Even within the state of Western Australia (WA), the

Simple Cycle, Combined Cycle, or a Hybrid Approach?
Simple cycle gas turbines provide efficiency levels of around 35% to 40%. Combined cycle units boost efficiency to 60% and beyond. But another option is emerging that combines the attributes of simple and combined cycle designs. This hybrid configuration uses a single power turbine expander and recycles exhaust heat back to the combustor to combine […]

The Queensland SuperGrid Marries the Old and the New
The Australian state of Queensland is in the midst of a rapid changeover from coal to renewables. From 70% coal generation today, it is switching to 70% renewables by 2032. This means phasing out 8.1 GW of coal and some of its 3 GW of gas generation, while simultaneously building at least 25 GW of […]

Experience Shows Wet Compression Is Safe to Use on Gas Turbines
Back in the early 2000s, some controversy emerged about the practice of spraying large amounts of fog directly into the compressor. Some claimed that this led to blade erosion, pitting, and scaling. So, is it safe to use wet compression on gas turbines by pumping water droplets into the compressor inlet? The answer is yes—provided […]

Can Utility-Scale Power Boilers Safely Fire Hydrogen?
There is plenty of enthusiasm around hydrogen as a possible alternative fuel to natural gas in combustion processes. Some hope it can eventually replace natural gas in applications such as utility boilers. However, any transition to 100% hydrogen has plenty of challenges to overcome due to it having such fundamentally different combustion characteristics. This gives […]

Original Approach to Fogging Regains Popularity
MeeFog’s very first installation of inlet air fogging was done at Harbor Cogen in Southern California in 1991 on a GE 7EA turbine where it continues to be used for power augmentation to this day (Figure 1). When it was installed, the fogging arrays were placed upstream of the air filters. Since that time, more […]

What Does It Take to Bring Stability to a Renewable-Focused Grid?
As coal, gas, and nuclear plants are retired, and wind and solar resources are added to the power grid, stability can become a problem. Understanding the solutions that are available to help manage potential issues is important for decision-makers so they can select the best options for their system. Grid stability and system strength have […]
