Canada's primary underground propane inventories increased by 19.79% in August, according to the Canada Energy Regulator (CER). The total represented a month-to-month increase of 233.3 Mcm. Compared to a year earlier, stocks were lower, with 401.5 Mcm, or 22.13%, less product on hand. 

Propane storages in the West started August a bit higher at 1010.6 Mcm, which corresponds to 6.367 MMbbl, the agency reported. From July to August, volumes increased by 223.4 Mcm, or 28.38%, and were 81 Mcm more than the year prior's level of 929.6 Mcm. Propane storages in the East started August higher at 401.8, commensurate with 2.531 MMbbl. This gain put propane 9.9 Mcm, or 2.53%, higher for the month, with a decrease of 482.5, or 54.56% below a year earlier. 

Canadian butane inventories stood at 1191.8 Mcm at the beginning of August, for an increase of 150.7 Mcm, or 14.48%, from July. Like propane, the year-over-year comparison finds butane volumes to be higher than the prior year's total, with inventories 144.8 Mcm, or 13.83%, above 2020. Western butane supplies, at 695.2 Mcm, were higher by 41.3 Mcm, or 6.32%, from the previous months and were 66.2 Mcm, or 10.52%, more than last year. Eastern butane, at 496.6 Mcm, was 109.4 Mcm, or 28.25%, higher month over month, and totaled 78.6 Mcm, or 18.80%, above a year earlier.
