In my lighting column published in the February issue of ELECTRICAL CONTRACTOR, I tackle the topic of DC building microgrids.

Throughout the age of alternating current, few imagined that direct current would reemerge as a viable primary power distribution option at the grid, community or building level. DC and hybrid AC/DC microgrids, however, have gained interest in recent years due to the proliferation of renewable energy, demands for backup power during grid failures and potential efficiencies that can be gained by directly connecting DC power to DC end-use devices, such as LED lighting and controls.

If this nascent trend grows, it could present opportunities and challenges for ECs…
