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.
By connecting utilities and leveraging diverse renewable resources across the West, the EIM is dramatically lowering greenhouse gas emissions and helping to unlock the full potential of a low-cost, reliable and resilient energy system.
Reduced emissions
Together with our diverse energy investments, the EIM has helped us cut our portfolio carbon emissions by 35 million metric tons.
Customer savings
The EIM reached a new historic milestone, reporting $5 billion in cumulative benefits for entities participating in the rapidly growing real-time energy market.
- At PacifiCorp, we’ve saved our customers $745 million so far, and the savings get bigger every year. See all benefits reports »
