This allows utilities to manage voltage, power flow, and reactive power support across the entire network enhancing overall grid reliability and resilience. For instance, in 2024, The DOE awarded nearly USD 2 billion to 38 projects under its Grid Resilience Utility & Industry Grants initiative. These projects mandate utilities to integrate medium-voltage capacitors.
   
• Industries can improve energy efficiency and reduce carbon emissions within their own facilities by installing medium-voltage capacitors for power factor correction. This reduces their electricity bills, avoids utility penalties for poor power factor, and lowers their carbon footprint, driving increased adoption in the industrial sector. For instance, in 2024, a DOE-supported project in a steel manufacturing plant in Ohio installed capacitors that improved the plant’s power factor from 0.75 to 0.95. This adjustment resulted in a 15% reduction in electricity costs and decrease in CO2 emissions due to lower energy demand.
   
• Capacitors play a vital role in supplying reliable electricity with minimal disruptions and consistent, high-quality power. Utilities are investing in capacitors to strengthen grids against faults by rapidly supporting voltage during sudden changes, including large motor or generator trips. For instance, in 2024, ARENA funded a project of USD 5.4 million in New South Wales to install medium-voltage capacitors in the grid to enhance power quality and resilience. These capacitors were deployed to support voltage during peak demand periods and mitigate the impact of renewable energy fluctuations.
