NWAU calculators 2019-20

To assist in applying the annual NEP price weights and adjustments, IHPA has developed versions of the National Weighted Activity Unit (NWAU) calculators described in the National Pricing Model Technical Specification. Each iteration of the NWAU calculators includes a user guide which outlines the introductory steps required to download and operate the calculators in Microsoft Excel.

NWAU calculators are available for each service stream. Excel-based NWAU calculators are provided on the IHPA website. SAS-based calculators have been provided to jurisdictions and are available on request by emailing enquiries.ihpa [at] (subject: SAS-based%20NWAU%20calculators) .
