Your heating and cooling system is the biggest user of electricity in your home. When outside temperatures are unusually high or low, your energy costs can spike significantly in a given month. To help take some of that weather-driven volatility out of your electric bill, SCE&G introduced the electric Weather Normalization Adjustment – or WNA – program in August 2010.
What is the WNA and how does it work?
With WNA, you are charged for the energy you use at a rate that’s adjusted to reflect normal temperatures. “Normal” is based on average temperatures over the past 15 years for a given billing period. Each month, WNA appears on your bill as either an increase or decrease to the cost you’re paying per kilowatt hour of electricity. A minus sign in front of the WNA factor indicates your rate was adjusted down for that bill. A plus sign signifies your rate was adjusted upward.
Why did SCE&G implement the WNA?
The goal of the WNA is to reduce the effects of extremely hot or cold weather on the customer and the company. The WNA helps reduce large spikes in your electric bill during periods of extremely hot or cold weather while also allowing SCE&G to continue to recover normal operating costs and provide you with safe, reliable electric service in any weather condition..
Will my bill adjust every month with the WNA?
It is possible that your bill will change from one bill to the next based on weather. Adjustments are indicated by an increase or decrease to the cost per kWh. A minus sign in front of the WNA factor indicates your rate was adjusted down for that bill. A plus sign signifies your rate was adjusted upward.
How is the WNA rate determined?
The method used to determine the WNA factor is approved by the Public Service Commission of South Carolina (PSC). It is unique to each customer based on type of residence, rate and other individual billing factors. It also changes from one bill to the next based on weather.
Will the WNA make all my bills the same amount?
No. The WNA is not the same as SCE&G’s Budget Billing Plan, which totals your annual electric usage and averages it over 12 months so that your bill is the same amount each month. To learn more about Budget Billing, please visit our Budget Billing page.
