Sierra Club seeks public disclosure of PacifiCorp coal plant study

Portland Business Journal:

The Sierra Club on Monday formally asked Oregon utility regulators to require PacifiCorp to divulge results of a company analysis into the economics of its coal power plants.

The environmental group is pushing for earlier coal retirements than PacifiCorp plans, and suspects the study could make its case.

A PUC order allows PacifiCorp to keep “commercially sensitive and confidential business information related to the company’s long-term resource planning” under seal. But the Sierra Club said the utility hasn’t demonstrated how it could be harmed by release of the coal analysis.

The coal analysis was ordered by the PUC as part of PacifiCorp’s 2017 integrated resource plan, which is largely wrapped up. The company will introduce its next IRP in April 2019.

Last month, PacifiCorp shared a presentation about the study with stakeholders who had agreed not to disclose any information about it. That presentation was made public, but with redactions.

“PacifiCorp redacted the study results to the extent that no reader of the PowerPoint could discern anything beyond the study’s methodology and its purported caveats and limitations,” the Sierra Club said in its filing. “PacifiCorp hid all of the study’s findings.”
