Why do electric rates vary by state?

The biggest reason states have different prices for electricity is their differing fuel mixes: the cheaper the source of power, the cheaper the electricity rate. Usually.

For example, a large part of the reason that states in the Northeast have higher than average electricity prices is because of the region’s heavy reliance on natural gas, which is a relatively expensive source of electricity. In contrast, most states in the South rely on coal and nuclear power, which are less expensive than other sources. Additionally, the South and Northwest both have much more hydroelectric power than other regions, which is one of the cheapest overall sources of power.

Do electric rates vary throughout the year?

In short, yes. In states that have more clearly defined seasons or a higher chance of extreme weather, this variation is especially pronounced. For example, in southern states, heat waves often cause spikes in electricity prices due to a spike in demand from homeowners trying to power their air conditioning. Just like any other product, when demand is high, prices usually follow.

How can I save on electric bills?

Saving on electric bills comes in two main forms: using less electricity and offsetting your costs. On one hand, you can change your behaviors and use efficient appliances to reduce your bills. And on the other, subscribing to a local community solar project, installing rooftop solar panels, or switching your electricity supplier through WattBuy’s energy marketplace will help you offset the money you pay to your utility for electricity.
