WPP is a 501(c)(6) membership organization with corporate members. The rights of corporate members are described in WPP’s bylaws.

Historically, WPP’s members have been electric load-serving entities participating in various WPP-facilitated reliability programs. With the recent changes to WPP’s bylaws, these members, referred to in the bylaws as “Program Signatories,” remain members of WPP. They maintain all of the rights they enjoyed in the past, as well as additional rights, such as the opportunity to be appointed to serve on WPP’s Nominating Committee.

More recently, and in recognition of the more public role served by WPP as administrator of the Western Resource Adequacy Program, WPP’s bylaws were modified to allow the addition of new types of members, called “Allied Partners.” These new, non-voting members may be ineligible to participate in WPP reliability programs, but may wish to stay abreast of WPP events, may seek the opportunity to serve on WPP’s Nominating Committee or other committees that may be established over time, or may wish to participate in members-only events or programs that may be scheduled.
