Hot weather’s impact on monthly utility bills

Posted | September 10, 2018

Our service area continues to experience above average temperatures.

  • Hot weather continued in August.
  • Your utility bill is impacted by increased energy use.
  • Follow a few simple tips to better manage monthly costs.

The summer's trend of scorching heat continued in August, especially as the month came to an end. In Louisville, the National Weather Service reports there were 20 days with above normal temps and at least nine of those days were in the 90s. Across Kentucky, the trend was similar. Louisville was also the 5th rainiest August ever.

So, what does this mean for your utility bill? Prolonged heat can lead to higher energy use for our customers, because air conditioning units are forced to work overtime, even in the overnight hours.

Over time, all of the extra work by your A/C to keep your home cool and comfortable adds up and is reflected on your monthly utility bill.

To offset higher energy use, we encourage customers to follow some easy energy-saving tips to stay cool now and through the summer months.

September’s outlook from the Climate Prediction Center has above normal temperatures and near normal rain for parts of our service area.

The amount of energy needed to cool your home or business can rise significantly when summer-like temperatures grip the region, which ultimately impacts your energy bill. The National Weather Service data show temperatures for the month of May that are above normal, with highs near 90 degrees and lows in the 60s and 70s.

As a reference point to the weather’s impact on energy use, this weather calendar features the average temperature for each day in 2018 as well as the average temperature for the same day last year.
