Benefits of a regional energy market

A regional energy market would better use resources, especially renewables, to reduce greenhouse gas emissions and costs. Enabling the ISO’s sophisticated market and grid optimization systems to pick the lowest cost energy to serve demand and give preference to renewable resources across a wide geographic region also means grid planners can build a cleaner, more resilient energy generation and delivery network that will create tangible economic benefits.

PacifiCorp announces plans to study integrating with the ISO

​On April 14, the ISO and PacifiCorp announced they had signed a memorandum of understanding (MOU) that commits the parties to explore the feasibility, costs and benefits of full participation by PacifiCorp in the California ISO. A comprehensive benefits study is underway. Should PacifiCorp decide to take additional steps to pursue joining the ISO following the benefits study, a full stakeholder and regulatory review and input process would be initiated.
