Grid modernization

Because electric service is essential for homes, businesses and communities, we go to great lengths to keep our grid safe and reliable for customers. We're developing innovative solutions and leveraging technology to make our grid more efficient, resilient and secure.

Energy Imbalance Market

PacifiCorp and the California Independent System Operator launched the Energy Imbalance Market (EIM) in November 2014. The EIM uses a sophisticated system to automatically balance demand every five minutes with the lowest cost energy available across the combined grid.

The EIM leverages the growing diversity of renewable resources, flexible backup resources and demand using advanced technology to keep energy supply affordable and reliable.

Smart grid technology

To give customers more insight into their energy use and for faster outage response, we’re piloting the use of smart grid technology. 

In many areas, we’re installing smart meters for a smart grid. Using two-way communication, the smart grid can automatically reroute the flow of energy when an outage occurs. The result: outages that are less common and less extensive.

The smart grid also increases the overall efficiency of the energy system and improves our ability to integrate clean, renewable energy sources.

With convenient online and mobile tools, customers can view their energy use and take steps to save energy and money.
