Update of Offsite Costs

Published December 2013

We last looked at capital costs of plant utilities in PEP Report 145B "Offsite Investment Cost Estimation." That report was written in 2006 and was based on information from 2004. Since then capital costs in the chemical process industry have nearly doubled. In this review we update the capital costs for four outside battery limits (OSBL) utilities: steam generation, cooling water, refrigeration, and inert gas generation. All of the capital costs presented in this review were prepared on a US Gulf Coast, fourth-quarter 2013 basis (PEP Cost Index = 1,164).
