Seasonal Variance and Personal Variance

How do seasons and personal energy usage impact costs?

Your electricity bill varies significantly by season.  If you live in Texas, you’re likely using relatively little energy during the winter months and likely using lots of energy during the summer months.

We use data below from a randomly selected sample of twenty-five Energy Simply customers from Texas.

SEASONAL VARIANCE: Look at the line in the graph below labeled “TX Average.”  The horizontal line labeled “1” below represents average usage.  Looking at the six months from November to April, electricity usage is well below average; but for the three summer months from June to August, usage is well above average.  If your average usage was around 1,000 kWh, you would want to find the best plan for 750 kWh in the winter months and around 1,500 kWh in the summer months.  Rarely is one plan the best plan at both of these usage levels so you’ll want to be switching plans when the seasons change (or let Energy Simply do this for you.)

PERSONAL VARIANCE: Seasonal variance is a big factor in choosing the best plan for you, but personal variance is also very important.  “TX Customer 1” and “TX Customer 2” represent two customers from the randomly selected sample of 25.  They illustrate the significant variance individuals might have even from the average.  Assuming an average monthly usage of 1,000 kWh for both of these customers, “TX Customer 1” used more than 2,500 kWh in June; more than 2.5x their average.  “TX Customer 2” used about 333 kWh in February and March; about 1/3 of their average.  Most plans that are good deals at 2,500 kWh/month are not so good at 1,000 kWh or 500 kWh; and same for plans that are good deals for 500 kWh/month aren’t often so good for 1,000 kWh/month or 2,000 kWh/month.

If you want to be in the best plans for your personalized usage, you should be changing with the seasons (or letting Energy Simply do this for you.)
