The Oregon Department of Energy has published their 2021 report titled, "Regional Transmission Organization Study: Oregon Perspectives" located at 2021-Regional-Transmission-Organization-Study.pdf (oregon.gov)
Below is the first paragraph of the Executive Summary:
The electric sector is in a period of rapid transformation as Oregon and many other states pursue aggressive decarbonization goals to mitigate the effects of climate change. This has led to revisiting old assumptions and confronting substantive barriers to increased regional collaboration and coordination. As directed in SB 589 (2021), this report presents the Oregon Department of Energy’s (ODOE or Department) findings from reviewing recent literature and engaging with a diverse range of stakeholders on the perspectives in the state on the opportunities, barriers, and challenges to the potential development of a Regional Transmission Organization, known as an RTO, that can benefit Oregonians. The Department has identified widespread, though certainly not universal, agreement among stakeholders on the value of increased regional coordination and collaboration, but it also identified a need to delicately balance competing interests—across different types of utilities, state and federal entities, various states, and other interested stakeholders—in order to forge solutions that achieve the common objectives of stakeholders inside and outside of Oregon.
