Propane storages in the West started June a bit higher at 475.2 Mcm, which corresponds to 2.994 MMbbl, the agency reported. From May to June, volumes increased by 208 Mcm, or 77.84%, and were 37.6 more than the year prior's level of 437.6 Mcm.  

Propane storages in the East started June higher at 241.9, commensurate with 1.5239 MMbbl. This gain put propane 15.9 Mcm, or 7.04%, higher for the month, with an increase of 122, or 101.75% above a year earlier. 

Canadian butane inventories stood at 719.8 Mcm at the beginning of June, for an increase of 127.4 Mcm, or 21.51%, from May. Like propane, the year-over-year comparison finds butane volumes to be higher than the prior year's total, with inventories 140.2 Mcm, or 24.19%, above 2022.  

Western butane supplies, at 494 Mcm, were higher by 65.8 Mcm, or 15.37%, from the previous months and were 56.3 Mcm, or 12.86%, more than last year. Eastern butane, at 225.9 Mcm, was 61.7 Mcm, or 37.58%, higher month over month, and totaled 84 Mcm, or 59.2%, above a year earlier.
