Spanish industrial gas burn last month was higher than in April but the lowest for May in at least nine years, the latest data from grid operator Enagas show.
Industrial gas demand of 449 GWh/d in May edged up from 441 GWh/d in April, but remained lower than the 465 GWh/d a year earlier and was the weakest for May since at least 2016, when Enagas' public dataset begins.
Before last month, the lowest industrial demand for May over the past nine years occurred in 2024, when Mibgas day-ahead reference prices averaged €32/MWh.
Spanish industries last month also consumed less gas than in May 2022, when day-ahead reference prices on the Mibgas exchange averaged €77/MWh, more than double the Argus-assessed €34/MWh day-ahead average last month.
Spanish industrial demand has remained lower on the year every month so far in 2025, largely because of limited gas use by refineries. Spanish refiners last month consumed 84 GWh/d, down from 100 GWh/d in May 2024, but the sector still accounted for the largest single portion of industrial demand.
There was also a significant decline in demand from the food sector, which decreased by 13pc on the year, combined heat and power (CHP) plants (11pc drop) and the paper sector, which fell by 7pc on the year.
Gas burn by CHPs last month held lower on the year, despite overall demand for Spanish power generation holding more or less stable and Spanish renewables and nuclear plants contributing less to the mix. That change may at least partly relate to stronger competition from combined-cycle gas turbines, which generated 4.4GW last month, 63pc higher than a year earlier.
The metal, chemical and construction sectors all used marginally more gas on the year, but that change only partially offset the decline in other sectors (see table).
