Gas distribution stations like this regulate pressure and meter flow for residential and commercial customers. Typical capacity for such stations ranges from small to medium, supporting local distribution networks. This substation plays a key role in delivering natural gas to Castro Valley and surrounding communities. Its location in a seismically active region requires robust infrastructure design and regular inspections to ensure safety and reliability.
