In accordance with TUC §141.003
, a retailer shall charge a just and reasonable monthly rate. A rate is just and reasonable if it is less than or equal to the allowable spot price plus the allowable markup. A retailer may also charge customers special fees for services such as a monthly account fee to maintain an active account, a late payment fee, a connection fee, etc. Certain taxes and other governmental fees may also be passed through to customers without any additional mark up.
