Alliance pushing DC power for homes and small businesses


An industry association pushing the adoption of safe direct-current (DC) power distribution standards for buildings says after five years focused on the commercial building space, it's time expand its work. EMerge leaders cite the increasing percentage of home electronics running on DC power, combined with the rapid expansion of rooftop solar which generates power in DC form.

"We have seen the sustainability, flexibility and reliability advantages that DC power provides to commercial building spaces, and it’s time to extend these benefits to homes and small businesses,” said EMerge Alliance Chairman Brian Patterson.  "DC power distribution would not only maximize the efficiency and ROI of rooftop solar panels by enabling them to directly power consumer electronics, appliances, LEDs and electric vehicles (EVs) without conversion losses, it could also give homeowners a choice to either store excess DC power or continue selling it back to power companies.”

According to the EMerge announcement, the new initiative will include "the hybrid use of alternating-current (AC) and DC power by defining interfaces with existing AC power systems at various upstream and downstream levels, with the goal of providing plug-and-play convenience for homes and small businesses."

EMerge, which launched in 2008, says its next step is to form a technical committee and anticipates collaborating with groups like the IEEE on the effort.
