Decoding “Flat Charge” and “Base Charge”

Life was simple only comparing “Energy Charge”.
Recently “Flat Charge” plans are all over PTC.
Let’s make it simple again here.

Flat Charge
= Energy Charge + Delivery Charge
= (electric company charge) + (Oncor charge)

We know its Flat Charge and Oncor’s Delivery Charges.
How much is its Energy Charge?

Let’s assume the monthly usage is exactly 1000 kWh.

Based on this assumption, for example currently:
* Frontier Power 5’s Flat Charge (Energy+Delivery): 6.42 ¢/kWh
* Oncor’s Delivery Charges: $3.42 /mon + 3.922 ¢/kWh

Its Energy Charge (@ 1000 kWh/mon)
= Flat Charge - Oncor’s Delivery Charges
= Flat Charge - ($3.42/1000kWh) - 3.922 ¢/kWh
= 6.42 - (342/1000) - 3.922 (¢/kWh)
= 2.156 (¢/kWh)

This “equivalent” Energy Charge (@ 1000 kWh/mon) will be shown in weekly suggestions for reference.

===============
Another variant is Energy Charge with “Base Charge”.

Let’s assume the monthly usage is exactly 1000 kWh.

Based on this assumption, for example currently:
* Direct’s Energy Charge: 1.9 ¢/kWh with Base Charge: $4.95 /mon

Its Energy Charge (@ 1000 kWh/mon)
= 1.9 + ($4.95/1000kWh)
= 2.395 (¢/kWh)

This “equivalent” Energy Charge (@ 1000 kWh/mon) will be shown in weekly suggestions for reference.
