UniSource Energy Summary Higher gas costs will not affect customers of

TEP or UNS Electric this winter Impact of higher wholesale prices on UNS Gas

customers has been mitigated somewhat by price stabilization policy for gas purchases

UNS Gas is making proactive, continuous efforts to communicate with customers about gas costs and inform them of programs that can make their home heating bills more manageable
