Propane storages in the West started August a bit higher at 876.4 Mcm, which corresponds to 5.521 MMbbl, the agency reported. From July to August, volumes increased by 85.6 Mcm, or 10.82%, and were 134.2 less than the year prior's level of 1010.6 Mcm.  

Propane storages in the East started August higher at 506.1, commensurate with 3.188 MMbbl. This gain put propane 134.6 Mcm, or 36.23%, higher for the month, with an increase of 104.3, or 25.96%, above a year earlier. 

Canadian butane inventories stood at 1155.9 Mcm at the beginning of August, for an increase of 166 Mcm, or 16.77%, from July. Like propane, the year-over-year comparison finds butane volumes to be lower than the prior year's total, with inventories 35.9 Mcm, or 3.01%, below 2022. 

Western butane supplies, at 629.8 Mcm, were higher by 59.6 Mcm, or 10.45%, from the previous month and were 65.4 Mcm, or 9.41%, less than last year. Eastern butane, at 526.1 Mcm, was 106.5 Mcm, or 25.38%, higher month over month, and totaled 29.5 Mcm, or 5.94%, above a year earlier.
