Energy efficiency in our operations
One of the metrics we use to measure our performance is energy intensity: the amount of energy consumed for every unit of output.
The refinery energy intensity index increased from 95.6 in 2022 to 98.7 in 2023, in part due to lower utilisation at several sites.
Energy intensity – refining
Refinery Energy Index [A]
Chemical steam cracker energy intensity in 2023 was 20.3 gigajoules per tonne (GJ/tonne) of high-value chemical (HVC) production, up from 19.3 GJ/tonne HVC in 2022. The increase was due in part to economic under-utilisation and less demand across our sites.
Energy intensity – chemical plants
Chemical energy intensity – gigajoules per tonne of production
In 2023, the overall energy intensity for the production of oil and gas in our Integrated Gas and Upstream business (excluding liquefied natural gas and gas-to-liquids) decreased from 1.19 in 2022 to 1.18.
