Line chart showing NGI's SoCal Citygate natural gas prices versus SoCalGas core storage volumes from January 2024 to May 2025. The chart highlights spot price fluctuations, ranging from below $2.00 to over $6.00/MMBtu, and compares them against the shaded area representing core storage levels in Bcf, bounded by dotted lines for historical min/max ranges. The graphic illustrates seasonal trends, with notable price spikes during early 2024 and early 2025, alongside consistent storage injections leading into summer. Data sources include NGI's Weekly Gas Price Index and SoCalGas ENVOY.
