PowerShift™

Save money by shifting your electricity usage
to "off-peak" time periods.

Sometimes, just by changing when we do things we can save money. Like flying a "redeye," getting summer hotel rates or going to a matinee movie.

Now you can get the same kind of non-prime-time discounts from UniSource Energy Services. It’s all part of the PowerShift time-of-use monthly pricing plan. By shifting the bulk of your electricity usage to off-peak, you can save money and help support a cleaner environment.

How does PowerShift work?

The first step to saving under PowerShift is conservation – eliminate unnecessary energy usage and use energy-efficient appliances and lighting. Then, by shifting the bulk of your remaining on-peak (highest-priced) and shoulder-peak (mid-priced) electricity usage to off-peak (lowest-priced) you will save money and help support a cleaner environment. So first conserve – then shift.

Initial setup of a PowerShift pricing plan is free, including the installation of a new electric meter. With PowerShift, the time of day will determine how much you pay for each kilowatt-hour (kWh), so the new meter will track actual time of use. When calculating the bill, UES will apply the appropriate rate to the kWh used in each different period. Rates for Standard Residential and PowerShift appear under the Rates tab.

PowerShift helps us all.

By conserving and shifting your usage, you also help reduce the need for UES to build and operate new power generation stations, which saves everybody money and even helps protect the environment.

Ideas on how to shift your electic use.

  • Set timers on pool or spa pumps to run during off-peak hours.
  • Operate washing machines, clothes dryers, dishwashers and non-essential appliances during off-peak hours.
  • Adjust your air conditioning thermostat to a higher temperature and heater to a lower temperature during peak and shoulder hours or when you are not at home.
  • Install timers on electric water heaters or recirculation pumps so they operate mainly during off-peak hours.
  • Turn off unneeded lights during peak and shoulder hours.
  • Enjoy recreational baking and electricity-consuming hobbies during the off-peak hours.

Could a PowerShift pricing plan end up costing me more every month?

Although you may see a slight increase in your summer electric bills under a PowerShift time-of-use (TOU) rate, the savings you gain during the six months of November to April will help you lower your annual electric costs.

These time-of-use rates are offered as an incentive to shift your electric use from on-peak to off-peak hours, particularly during the summer. Being on a PowerShift time-of-use rate will require you to make adjustments in your daily routine. If you don't change your energy usage patterns, you could pay more.

So, it's up to you to shift your electricity usage to the less expensive off-peak hours, especially for large appliances like dishwashers, air conditioners, electric heating systems, electric ovens or clothes dryers.

Can a PowerShift pricing plan save me money even if someone is home during the day?

You can save money even if you're home during peak hours. All you need to do is shift electricity usage to off-peak hours. Make some changes in your usage habits and you can be on your way to saving money.

Is there a specific length of time I must remain on PowerShiftt?

You should plan to remain on a PowerShift pricing plan for at least a year in order to realize annual savings on your electric bill.

How will I know if I'm using electricity more efficiently?

Just save your electric bills and see if your off-peak electricity usage changes over time, and your on-peak usage goes down. If you find you're using more energy during the low demand, low-price times of day, then you're being a very careful consumer.

Why do power costs fluctuate so much?

When customers use more electricity, the market price for wholesale energy goes much higher. Price is almost always affected by the laws of supply and demand. In the winter, the costliest times are when we start our day, and at dinner. In the summer, our system peaks during the afternoon and early evening until dusk.

Why should fluctuating wholesale energy prices concern me?

Electric utilities pay much more for power during high demand periods of the day. Our costs eventually become your costs. So the more you shift energy use to the low-cost, low-demand times, the less you end up paying. Over time, your success helps our entire community.

By conserving and shifting your usage, you also help reduce the need for UES to build and operate new power generation stations, which saves everybody money and even helps protect the environment.

What can I do in my home to conserve energy and get the most savings from PowerShift?

Set timers on pool or spa pumps to run during off-peak hours.

Operate washing machines, electric clothes dryers, dishwashers or non-essential appliances during off-peak hours.

Adjust your air conditioning thermostat to a higher temperature and heater to a lower temperature during peak and shoulder hours or when you're not at home.

Install timers on electric water heaters or recirculation pumps so they operate mostly during the off-peak hours

Turn off all but essential lights during peak and shoulder hours. For even more savings consider replacing your incandescent bulbs with energy saving compact fluorescent bulbs. They can last up to 10 times longer than incandescent bulbs and can save you up to 75% in operating costs.

Important information.

All charges specified are per kilowatt-hour (kWh).

Changes in your household’s energy habits may be necessary. Timing is everything! The more you are able to shift usage away from peak hours, the better off you'll be. An average residential customer shifting two-thirds of peak and shoulder electricity usage to off-peak can save around 6 percent on his or her annual electric bill. Savings will vary based on individual usage patterns.
