The Bonneville Power Administration completed the final environmental impact statement for our proposed I-5 Corridor Reinforcement Project
, and released it in February 2016. The final EIS is a significant milestone in completing the National Environmental Policy Act review process for this proposal. BPA’s preferred route for the transmission line remains the Central Alternative using Central Option 1
. However, we are not done yet.
The Administrator has not yet made a decision about the I-5 Corridor Reinforcement Project. BPA continues to perform and prepare analysis to inform the administrator’s decision. BPA recognizes the potential stakeholder and cost impacts of such a decision, and remains committed to making the right investment at the right time. We appreciate the patience and input from our customers and the community. This is a large project with profound implications for landowners in the greater Portland-Vancouver area and for BPA ratepayers.
To that end, BPA conducted a regional transmission review between February and September 2016 with various northwest utilities that impact the I-5 transmission corridor. This process reviewed the methods and assumptions that determined the need for the project. BPA also continues to analyze multiple drivers in greater depth, including:
Non-wires opportunities, benefits and associated costs compared to various build alternatives;
Evolving market conditions and other Pacific Northwest utility plans and initiatives;
Impacts to BPA’s transmission rates from various alternatives;
Analysis of potential financial impacts of various scenarios on BPA’s overall debt costs.
If BPA decides to build the transmission line, we would prepare and issue a record of decision that announces and explains our decision to build the project. The record of decision also would identify which route alternative we have chosen to construct.
In the interim, BPA will continue to work and communicate with our cooperating agencies, as well as with other federal, state, regional, and local agencies and officials, tribes, landowners, interest groups and citizens. Please contact us
