HB 169 changes how New Hampshire's Public Utilities Commission operates. It requires the 3-member commission to include one attorney and one member with technical/economic expertise (like engineering or finance), with all commissioners serving full-time 6-year terms. The bill also lowers the quorum needed for decisions: 2 commissioners (a majority) can now conduct hearings, issue orders, or establish rules, rather than requiring all 3 members. This allows the commission to function even with vacancies.
