TGOOD Global has been operating since 2014 and we are reflecting on the past ten years of our involvement in the electrical engineering field. Since our beginning we have grown more than 30 times in size, having completed more than 400 projects. We have subsidiaries in 5 locations around the world and now deliver to 19 countries. A lot has changed in the past decade, including innovations in MV and HV switchgear, ehouses and substation kiosks. These technological developments have been driven by the need for greater efficiency, sustainability, and reliability in power distribution systems.
In 2014, many people in Western countries acknowledged climate change but often viewed it as a distant issue. By 2025, a growing majority believe its effects are already being felt, such as through extreme weather events like floods, droughts, and wildfires. Surveys show that concern about climate change has reached record highs, with younger generations particularly vocal about the need for action. TGOOD Global is responding to the real need for reduced carbon emissions by coming up with better ways to manufacture, install, run and decommission power equipment.
1. Advancements in MV and HV Switchgear
Switchgear technology has evolved to improve safety, efficiency, and environmental impact. Some notable changes include:
- Gas-Insulated Switchgear (GIS): The shift from SF₆-based insulation to alternative eco-friendly gases has reduced environmental impact.
- Digital Switchgear: Integration of IoT and smart sensors allows for real-time monitoring and predictive maintenance, reducing downtime.
- Arc Quenching Systems: Innovations like vacuum technology and the arc killer significantly improve safety by rapidly extinguishing arc faults.
- Compact Modular Designs: TGOOD’s modern switchgear substations are smaller, lighter, and more adaptable, making installation easier and reducing space requirements.
Between 2020 and 2024 TGOOD Africa has provided hundreds of primary gas insulated switchgear to a copper mine in the DRC. TGOOD Australia has recently completed 17 MV substation kiosks for various customers in Western Australia and Queensland.
2. Evolution of Ehouses
Ehouses—pre-fabricated electrical substations—have become more versatile and efficient. Key developments include:
- Improved Mobility: Modular designs allow for quick deployment in remote locations, benefiting industries like renewables, mining and oil & gas.
- Enhanced Cooling Systems: Advanced HVAC solutions ensure optimal performance in extreme environments.
- Smart Integration: Ehouses now feature automated control systems for remote monitoring and diagnostics, reducing maintenance costs.
TGOOD Global has been designing, building and commissioning ehouses for sites in Australia, South Africa and other parts of the world since 2016. One of our recent ehouse projects was a 33kV switch room with control room for the Clean Energy Hub in Chinchilla, Queensland.
3. Innovations in Substation Kiosks
Substation kiosks have undergone major transformations to enhance reliability and safety. Some key improvements include:
- Prefabricated Modular Designs: These allow for faster installation and customisation based on specific power distribution needs.
- Environmentally-friendly Transformers: A shift from mineral oils to ester oil-immersed or dry type cast resin transformers has improved fire safety and reduced maintenance.
- Smart Grid Compatibility: Modern kiosks integrate with smart grids, enabling automated load balancing and fault detection.
You can find TGOOD substation kiosks across solar farms and BESS sites in Australia, including in Glenmore, Wakerley, Tomago, Greenbank, Newstead, Cootamundra, North Adelaide and the Western Downs.
4. Sustainability and Energy Efficiency
Environmental concerns have driven sustainable innovations in power equipment:
- Eco-Friendly Insulation: The move away from SF₆ gas to alternative insulating materials reduces greenhouse gas emissions.
- Energy-Efficient Components: Advances in power factor correction and low-loss transformers improve energy efficiency.
- Renewable Energy Integration: Substations and switchgear are now designed to seamlessly integrate with solar and wind power systems.

The past decade has seen remarkable advancements in MV and HV switchgear, ehouses, and substation kiosks, driven by the need for efficiency, safety, and sustainability. TGOOD’s contribution to the power equipment industry has brought great success for us as a company. We continued operating throughout the COVID-19 pandemic and are now achieving fantastic business growth. Best of all, our team knows that each and every one of us is helping to save the planet by bringing more renewable energy projects to fruition with more environmentally friendly practices and technology. As TGOOD’s engineering continues to evolve, these innovations will play a crucial role in shaping the future of power distribution and grid reliability.
