Facebook Data Center Substation - Altoona, Iowa | Electrical Infrastructure

The Facebook Data Center substation is an electrical substation located in Altoona, Iowa, United States. Operated by MidAmerican Energy, this facility operates at a voltage of 161 kV, placing it in the high-voltage transmission category. The substation is critical for distributing power to the adjacent Facebook data center and the surrounding region. As a 161 kV substation, it falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards to ensure grid stability. The substation likely employs modern switchgear and automation systems compliant with ISO/IEC 61850 standards for substation automation, common in the United States for efficient grid management. The substation plays a vital role in supporting the energy-intensive operations of the Facebook data center, which requires reliable and high-capacity power. Its location in Iowa, a state with a growing renewable energy sector, may also facilitate integration of wind and solar power into the grid. The facility contributes to the local economy and infrastructure resilience.

The substation is situated in a mixed urban and agricultural area in central Iowa. The region experiences a continental climate with hot summers and cold winters, which can affect grid demand and equipment performance. The facility's proximity to a major data center underscores the need for reliable power supply and potential for load management. Environmental considerations include electromagnetic field management and stormwater runoff control typical of substation operations.
