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 s/he is the Mayor. The other four members represent the four geographical quadrants of the City, and must reside within the quadrant they represent. 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 10 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 15 members, who must reside in the CPS Energy service territory and be customers of CPS Energy as well.
