TEP invests in the community in several ways:


Financial donations to non-profits or charities for programs or special events where volunteer assistance is not needed or would not be appropriate may be requested throughout the year.

In-kind donations

In-kind donations are non-monetary valuable goods including computer equipment, office furniture, printing (i.e. promotional material), or the lending of pop-up tents, traffic cones and more.

Corporate memberships

Corporate memberships are requests for annual membership at the corporate level to community organizations such as chambers of commerce, utility organizations and business groups.

Employee volunteer projects

Employee volunteer projects are employee-driven initiatives to support the communities where we live and work. These requests are typically supported and coordinated by Community Action Team employee volunteers.


Sponsorships are the support of events and activities in which a mutually beneficial arrangement is made between the organization and TEP. This may include the promotion of goods, products and services. The organization promoting the sponsorship is responsible for providing the value of the sponsorship that is tax-deductible.
