Subdivisions

At Perth Electrical Engineering Consultants (PEEC), we provide complete site power design for residential and mixed-use subdivisions across Western Australia — from single-lot strata projects to 100-lot greenfield estates. Our designs are compliant with Western Power, NCC, and relevant AS/NZS standards, giving developers and builders everything they need to tender, cost, and install electrical infrastructure with confidence.
