The growth of artificial intelligence (AI) and its supporting sectors is pushing the grid toward instability. Voltage fluctuations, frequency dips, or even brownouts will become much more common occurrences. Sensitive electronics (e.g., servers, HVAC controls, home electronics) can be damaged by these occurrences if not properly protected.
First, we need to understand the challenges our electrical grid faces due to rapid growth in this sector. After that, we will discuss measures to protect your equipment.
Massive and Variable Power Demand
- Data centers, housing the hardware for AI, are the primary drivers of this increased demand.
- Global electricity demand from data centers is projected to more than double over the next five years, potentially consuming as much electricity as Japan does today by 2030, according to the International Energy Agency.
- In the United States, data centers are projected to contribute nearly half of the growth in electricity demand by 2030. According to a study by the U.S. Department of Energy (DOE), electricity usage for data centers is expected to increase from 4.4% of total demand in 2023 to 12% by 2028.
- As AI adoption grows, demand spikes unpredictably and can stress generation and transmission systems.
- AI workloads are not evenly distributed—they can concentrate demand in areas not designed for it.
Grid Stability Risks
- Sudden ramp-ups in AI workloads can destabilize voltage or frequency, especially in grids with high renewable penetration.
- If demand response systems are not keeping up, localized brownouts or blackouts could occur.
Infrastructure Strain
- Existing grids are struggling to keep up with data center construction and demand, with 70% of U.S. transmission lines nearing the end of their useful lives, according to the DOE.
- Concentrating data centers in certain regions can strain local grids, potentially causing power quality issues or outages.
- An estimated $720 billion investment is needed for grid upgrades through 2030 to accommodate increased demand, according to a report from Goldman Sachs.
- Long permitting and construction times for transmission projects can create bottlenecks, hinder data center expansion, and potentially push U.S. companies to build infrastructure abroad.
Bottom Line
- This strain on the electrical grid can cause power surges, brownouts, and extended overvoltages. Conditions that can damage sensitive, expensive electronic equipment, especially HVAC systems using inverter technology. However, sensitive electronic circuits in general are at risk.
- The protection scheme against these conditions needs to address all three power disturbances: surges, brownouts, and extended high voltage.
