Our rates for natural gas service are determined through a combination of rules in the cities where our consumers live, the Railroad Commission of Texas (RRC), and market factors.

Understanding your bill

Our natural gas rates may appear in one of 3 categories on your monthly bill:

  • Environs - Residential or Commercial
  • Environs - Public Authority
  • Incorporated (within the city limits of Magnolia) - Residential or Commercial

​In October 2018, the RRC approved EPCOR’s request to refund nearly $250,000 in tax reform savings to the company’s natural gas customers. Until new rates are adopted by the RRC in a future rate case, rates for natural gas will be lowered to reflect the new lower tax rate beginning with the November 2018 bill.

Customers will also receive a one-time credit on the November 2018 bill, refunding corporate taxes collected at the higher rate in 2018. Credit amounts vary by customer class. Here's a full list of the rate reductions and credits.

Environs - Residential and Commercial Service Rates

Effective November 1, 2018

​Charge ​Price
​Monthly customer charge $17.06/bill 
Additional components of your gas bill​ ​
​Volumetric service fee ​$6.56/ccf*

​IRA 2014 surcharge ​$3.76/bill
​IRA 2015 surcharge ​$2.89/bill
​IRA 2016 surcharge ​$3.09/bill


*ccf = a measurement of natural gas volume that is equivalent to 100 cubic feet of gas
**IRA = interim rate adjustment

From December through February usage months, we use a weather normalization factor that can make the volumetric service fee go up or down.  

We are currently assessing IRA surcharges as an increase in the monthly customer charge.  The purpose of IRA surcharges is to recover incremental costs related to the capital investments the company has made in its natural gas distribution system for the years listed. Those costs are incremental to and not included in the rates in effect for unincorporated areas in the EPCOR distribution area.

These surcharges will appear on your bill until we apply for a full rate review before the Railroad Commission of Texas. This typically occurs every 5-6 years. The last rate review was in 2012.
