Crypto and AI Growth Could Strain North American Energy Grids, Warns NERC

The increasing demand for electricity in North America is reaching new heights due to the growth of cryptocurrency mining and artificial intelligence (AI) operations. Industries are connecting large-scale data facilities to the energy grid, putting a strain on the power supply and posing challenges to forecasting and reliability.

Growth in Electricity Demand Presents Challenges to Forecasting and Reliability

According to a report by the North American Electric Reliability Corporation (NERC), the growth in electricity demand is expected to present significant challenges to forecasting and reliability. The NERC report highlights the strain on grid reliability and the increased risk of energy shortfalls posed by crypto mining and AI operations.

Crypto Mining Power Use Can Vary, Adding Complexity to Energy Grid Management

The power use of cryptocurrency mining can vary depending on market prices, which adds further complexity to energy grid management. Sudden fluctuations in load requirements during normal operations also pose challenges to grid operators managing variable renewable energy resources.

Projected Growth in Electricity Demand by 2029

The NERC’s latest Long-Term Reliability Assessment shows that significant growth, particularly in regions like Texas, implies an increase of 4.6% annually to 2029 at peak summer demand, which is four times more than previous projections. The report highlights that AI data centers and crypto mining present unique challenges with their energy-intensive nature and varying load behaviors.

Risks to Reliability and Stability

With crypto and AI becoming mainstream over time, their associated operations pose significant challenges to energy grid stability and reliability amid potential grid strain, particularly during peak periods or operational faults. In Texas, where crypto mining and AI hubs are concentrated, the Electric Reliability Council of Texas (ERCOT) reports increasing risks associated with contracted and non-contract energy loads.

Sudden Load Changes in Crypto Mining and AI Industries Mimic Issues Seen with Inverter-Based Resources

Sudden load changes in the crypto mining and AI industries potentially mimic issues seen with inverter-based resources, like disconnections during faults or price spikes. This introduces new risks for grid operators managing variable renewable energy resources.

Strategies to Address Rising Electricity Consumption

NERC is calling for proactive measures to address the increasing strain on North America’s energy grid, suggesting improved demand forecasting, advanced transmission planning, and expanded demand-side management (DSM) programs. ERCOT has implemented energy response and demand response programs to balance the energy grid load during critical periods.

Legislation Introduced to Improve Reliability Assessments

Texas has also introduced legislation, like Texas’ HB 3390, which mandates improved distributed energy resources (DERs) tracking to improve reliability assessments.

Some Mining Firms Shifting Toward Renewable Energy Sources

In tandem with the increasing concerns, some mining firms are shifting toward renewable energy sources. For example, MARA’s (formerly Marathon Digital) acquisition of a wind farm in Hansford Country, Texas, is one such example.

Conclusion

The growth of cryptocurrency mining and AI operations in North America is driving demand for electricity to new heights. The strain on grid reliability and the increased risk of energy shortfalls posed by these industries present significant challenges to forecasting and reliability. Proactive measures are needed to address the increasing strain on the power supply, including improved demand forecasting, advanced transmission planning, and expanded DSM programs.

Recommendations

Improved Demand Forecasting: Implement advanced tools and techniques for accurate demand forecasting to mitigate the risks associated with crypto mining and AI operations.
Advanced Transmission Planning: Develop more efficient and effective transmission systems to accommodate the growing energy demands of crypto mining and AI operations.
Expanded DSM Programs: Encourage participation in demand-side management programs to balance energy grid load during critical periods.

Future Directions

The increasing demand for electricity due to cryptocurrency mining and AI operations is a pressing concern that requires immediate attention from policymakers, grid operators, and industry stakeholders. By implementing proactive measures and strategies, we can mitigate the risks associated with these industries and ensure a stable power supply for North America.
