Storing power to meet your needs

That’s a great question. Thanks for asking.

Q. I’ve heard a lot about battery storage and energy — what’s it all about?

A: Energy storage is about getting the most out of our renewable resources, especially as we add more renewable power to the mix (see our cleaner energy future story).

The challenge is that renewable power generation from the wind and the sun varies. For example, the wind often blows steadily at night, when less power is needed because people are sleeping and businesses are closed.*

That’s why we’re planning several energy storage projects of various sizes. These are big batteries that will store electricity generated by wind turbines, solar panels and other sources to make sure clean power is always available when you need it.

Testing different storage options

We recently filed a proposal with the Oregon Public Utility Commission to develop up to 39 megawatts of energy storage — that’s enough electricity to power about 31,000 homes.

We’re proposing a variety of pilot projects to test what’s most efficient and effective, including:

  • Batteries alongside existing generating plants, including solar and biomass facilities
  • PGE-controlled batteries at homes throughout our service area.

Based on our learning

These and other energy storage projects will build upon what we’ve already learned from the Salem Smart Power Center. The project uses state-of-the-art storage batteries and micro-grid technology (a smaller grid within the big grid that can operate independently if needed) to demonstrate how variable renewable energy sources, such as solar and wind power, may be stored for later use.

We’re dedicated to building a cleaner, smarter, more resilient electrical grid that’s also reliable and affordable. Energy storage is one way we can add more clean, renewable power and help decarbonize the electrical system.
