Your Electricity Bill
Making Sense of Your Electricity Bill
Understanding your electric bill can be straightforward. Start by looking at how many kilowatt-hours (kWh)
you used and then multiply that by the price per kWh. This gives you a rough idea of what your bill will be.
Use this formula to calculate the TDU Delivery Charges:
Estimated Electric Bill = (Rate per kWh) x (Electricity Used in kWh) + Monthly Fees.Example Centerpoint TDU 1000 kwh usage : (0.053509 x 1000kwh) + 4.39 = $57.90
Keep in mind, other charges like taxes might add a little extra.

Explanation:
TDU Delivery Rate
TDU Delivery Rate
The TDU (Transmission and Distribution Utility) delivery rate is a per-kilowatt-hour charge paid to your
local utility company. This fee covers the upkeep and operation of the infrastructure that delivers
electricity from the power plant to your home. Retail electricity providers collect this cost but pass it
directly to the utility company. The utility company sets these rates, which are reviewed and approved
twice a year by the Public Utility Commission of Texas (PUCT).
TDU Monthly Delivery Charge
TDU Delivery Rate
Alongside the per-kWh rate, TDUs also add a fixed monthly fee. This fee helps support the ongoing
management and maintenance of the power infrastructure in your area
Base Charge
Base Charge
A fixed monthly fee that remains the same regardless of how much electricity (kWh) you use.
Demand Charge
Demand Charge
This fee is calculated based on the rate at which electricity is supplied or used at a specific moment or
averaged over a set time within the billing cycle.
Energy Charge
Energy Charge
A cost determined by the total amount of electricity (kWh) consumed during the billing period.
The difference between a Fixed-rate and Variable-rate
A fixed-rate electricity plan provides consistent pricing by setting a stable rate per kilowatt-hour (kWh) for the
entire contract. This setup means your per-kWh rate doesn’t change, even if the market shifts. Many customers
appreciate the predictability of fixed rates for easier budgeting, as they’re shielded from sudden price hikes.
However, while the rate remains fixed, your total bill may still vary each month based on how much energy you
use.
On the other hand, a variable-rate (or market-rate) plan features a per-kWh rate that can change monthly,
influenced by energy market factors like fuel costs, supply and demand, and seasonal weather. This can mean
savings when prices dip, but there’s also a chance of higher costs during peak demand times. These plans often
don’t have long-term contracts, allowing for flexibility, though monthly bills may fluctuate, making budgeting
more challenging.
In short, a fixed-rate plan offers stability and is well-suited for those who want predictable costs. A variable-rate
plan may suit those who value flexibility and the opportunity to benefit from market decreases but are prepared
for potential increases in monthly expenses.
