Questions people ask
Can I choose my electricity provider in Port Arthur?
In most of Port Arthur, no: a local utility sells and delivers power. Some addresses near the city edge may be in a competitive area. Your bill shows your utility.
Why can’t everyone in Texas choose?
When Texas opened its electricity market in 2002, city-owned utilities and co-ops could decide whether to join. Most chose not to, so they set their own rates.
