Propane storages in the West started September a bit higher at 1012.6 Mcm, which corresponds to 6.379 MMbbl, the agency reported. From August to September, volumes increased by 136.2 Mcm, or 15.54%, and were 148.7 less than the year prior's level of 1161.3 Mcm.   

Propane storages in the East started September higher at 644, commensurate with 4.0572 MMbbl. This gain put propane 137.9 Mcm, or 27.25%, higher for the month, with an increase of 55.6, or 9.45% above a year earlier. 

Canadian butane inventories stood at 1283.6 Mcm at the beginning of September, for an increase of 127.7 Mcm, or 11.05%, from August. Like propane, the year-over-year comparison finds butane volumes to be lower than the prior year's total, with inventories 18.2 Mcm, or 1.4%, below 2022.  

Western butane supplies, at 690 Mcm, were higher by 60.2 Mcm, or 9.56%, from the previous months and were 22.3 Mcm, or 3.13%, less than last year. Eastern butane, at 593.6 Mcm, was 67.5 Mcm, or 12.83%, higher month over month, and totaled 4 Mcm, or 0.68%, above a year earlier.
