Time-variant electricity pricing

Time-variant electricity pricing gives customers control of their electricity bills

Throughout most of the country, residential customers pay the same price for electricity regardless of the time of day or year when it is used.

Also known as “flat rates,” these prices mask the true system costs of making, moving, and using electricity, which vary by time and location according to electricity demand. For example, high-traffic energy times occur predictably in the late afternoon when everyone is running air conditioners, cooking, watching TV, and doing laundry.

This “peak” demand also occurs during certain seasons, including summer and winter, when people require more energy to heat and cool their homes.

The potential

When customers don’t know the true price of electricity or how much they will pay at the end of the month, they do not have the basic information needed to conserve energy (and, thus, lower their bills) when it matters most.

Time-variant pricing better reflects the true cost of electricity, allowing people to choose when they power up appliances based on electricity prices at that time.

In addition to lowering electricity bills, this clean energy solution has the potential to reduce air pollution, improve grid resiliency, and optimize our use of renewable energy.
