Frequently Asked Questions

Texas-ERCOT Grid Emergency

MidAmerican Energy Services is committed to keeping our customers informed. The recent weather event in Texas forced an electric grid emergency. As a result, both energy prices and costs for supporting services designed to help maintain grid reliability increased significantly. We understand the challenges this weather event has created for our customers and we want to provide information to help you understand why this is impacting your monthly bill.

RESIDENTIAL CONTRACT CUSTOMERS

Do I have a fixed rate?

Yes, under the terms of your agreement with MidAmerican Energy Services, you enrolled under a fixed rate plan where the energy component remains fixed regardless of changes in market prices. MidAmerican Energy Services will not increase the energy component of your bill, however, non-energy costs such as ancillary charges billed by ERCOT and your local utility, are not fixed and are passed through on your bill.

Note: If your fixed rate has expired, you can view the variable rate which is published prior to the beginning of the billing cycle or enroll in a new fixed rate plan by visiting our website, www.MidAmericanenergyservices.com.

Why is my bill higher?

While the cost for your energy component is fixed, non-energy charges (including ancillary costs) are billed by ERCOT and your local utility that distributes the power. Non-energy costs are not fixed and are passed through based on changes in utility and ERCOT pass through rates. These costs are used to manage the grid and your local area network. You will see a new line item on your bill, Supplemental Ancillary Charges, for the increase in ancillary rates.

Ancillary costs are determined by ERCOT and your local utility for maintaining the integrity of the electric grid and as such performed rolling outages during the storm event. Ancillary costs are market-driven and can increase significantly during extreme weather events.

Will I be charged for the time I was without power?

Please be assured that you were not charged for any costs during the time you were without power. Your electric meter does not record usage when your power is out.

COMMERCIAL CONTRACT CUSTOMERS

How is my monthly bill calculated? / Why did the price per kWh increase?

Your monthly bill is made up of both energy costs and non-energy costs:

Energy Costs

Energy Costs (Fixed-Price Customers)

Under the terms of your agreement with MidAmerican Energy Services, the energy component remains fixed regardless of changes in market prices. MidAmerican Energy Services will not increase the energy component of your bill.

Energy Costs (Index-Price Customers)

Your contract is a market-index based product which means your cost per kWh is not fixed. Market index prices reflect real-time conditions on the electric grid. Due to extreme weather conditions, index prices were historically high – reaching the $9,000/MWh maximum price most days during the extreme weather event.

Non-Energy Costs (including Ancillary costs)

Non-energy costs include ancillary costs that are billed by ERCOT and your local utility that distributes the power. Ancillary costs are determined by ERCOT and your local utility for maintaining the integrity of the electric grid and as such performed rolling outages during the storm event. Ancillary costs are market-driven and can increase significantly during extreme weather events.

Non-energy costs such as ancillaries are not fixed and are passed through based on changes in the ERCOT tariff rates or market prices. You will see a new line item on your bill, Supplemental Ancillary Charges, for the increase in ancillary rates.

How is my monthly energy price determined?

Your monthly bill is made up of both energy costs and non-energy costs:

Fixed-Price Customers

Your energy price is defined in your contract and locked in for the term of the agreement.

Index-Price Customers

Usage is determined by the usage data received from the utility once your electric meter is read. The price is determined by using the hourly market rate for each hour of the bill period which is then averaged out by the number of days in the bill cycle and rolled up into one price.

Will I be charged for the time I was without power?

Please be assured that you were not charged for any costs during the time you were without power. Your electric meter does not record usage when your power is out.
