Governing structure

CPS Energy is governed by a five-member board of trustees. The mayor of San Antonio serves as an ex officio member, for as long as they are the mayor. Each of the other four members represents a geographical quadrant within the city, and must reside within that quadrant. They are nominated by the remaining trustees for a five-year term, with eligibility to serve one additional term. The nominations must be approved by majority vote of the San Antonio City Council.

In addition, a 15-member Citizens Advisory Committee serves as a liaison between CPS Energy and the citizens of San Antonio. Ten of the members are nominated by the ten City Council members (one from each district), while the remaining five are chosen from applicants who are interviewed by the Board. The Board approves all fifteen members, who must reside in the CPS Energy service territory and be customers of CPS Energy as well.^[14][15]
