What fuels your electricity?

When you flip on your light switch, do you ever wonder where that energy comes from? As an Avista customer, that electricity comes from a variety of sources.

Today, the amount of electricity needed can’t be stored in large quantities, which means it’s generated as you use it.

Some utilities rely on a single fuel to make electricity. To serve customers, our goal is to balance reliability with renewable energy while managing costs for customers. So we’ve created options.

What generation sources serve Avista customers?

By enabling us to choose the appropriate resources at any given time, a diverse energy mix helps balance reliability, the environment and the price customers pay for the energy they use now, and into the future.
