to increase in both primary markets ( 5.9 % to US $ 127.50 per kW ) and secondary markets ( 2.3 % to US $ 133.00 per kW ). Primary-market vacancy will remain tight for the foreseeable future , as 73 % ( 1,170 MW ) of the 1,601.5 MW of the underconstruction supply was preleased as of the end of H1 2022 .
“ Supply chain disruptions and a lack of available power and land in some major markets could delay new construction deliveries over the balance of the year and beyond ,” said Pat Lynch , Executive Managing Director , Global Head of Advisory & Transaction Services , Data Center Solutions , CBRE . “ As a result , we expect continued rising rents nationally and more occupiers turning to secondary and tertiary markets to meet their needs . These smaller markets will also continue to benefit from an increase in Edge data centre deployments , driven by broader adoption of AI , 5G and Blockchain technologies .”
