During the course of 2020/21, two major reviews were undertaken of the WA Electrical Requirements (WAER) and the WA Distribution Connections Manual (WADCM).
In July 2021, Horizon Power and Western Power finalised the WADCM review resulting in the publication of an updated and rebadged edition, entitled the Western Australian Services and Installation Requirements (WASIR).
The drivers for change, were critically important to ensure the technical requirements applicable to consumer network connections, aligned with an evolving renewable energy market and state/national compliance frameworks.
The WASIR, provides a detailed roadmap as well as links to a range of existing and new Horizon Power and Western Power published technical manuals, standards and guidelines associated with both traditional and emerging connection configurations.
The updated requirements are aligned with the pending introduction of the new 2021 WAER and network embedded generation/stand-alone power system standards and technical rules.
Sections 11, 12, 13, 14 and 15 of the WASIR should be studied in detail, given the number of changes that directly affect new, altered and or upgraded connections.
A more detailed description of the changes and the transitional path from the now superseded WA Distribution Connection Manual 2015 (WADCM) to the new WA Service and Installation Requirements 2021 (WASIR) is available from our website and Horizon Power's website.
Consumers and industry are encouraged to read and apply these requirements to all new consumer electrical installations as soon as practical but no later than six months from the date of publication (1st August 2021). WASIR clause 2.4 provides additional specific detail on the date of compliance and exemption criteria options.
