2023 CEPCI updates: September (prelim.) and August (final)

| By Scott Jenkins

The preliminary value for the CE Plant Cost Index (CEPCI) for September 2023 (the most recent available) fell compared to the August value, reversing the slight increase that was observed from the cycle prior to that. The CEPCI has been fluctuating up and down since the beginning of the year. The September 2023 decrease was driven by the Equipment and Buildings subindices, which both fell, offsetting small increases in the Construction Labor and Engineering & Supervision subindices. The current CEPCI value now sits at 3.4% lower than the corresponding value from September 2022. Meanwhile, the Current Business Indicators saw an increase in the CPI output index and the CPI operating rate for September 2023.
