At the settlement price of $39.50 per allowance from auction #15 on 2026-09-02 (Ecology’s summary report ↗), where 3,484,205 allowances were sold on behalf of consigning entities statewide. What the allocation would fetch at one auction's price. Utilities consign part of their allowances to these auctions and must return the proceeds to customers; the rest they hold for compliance or bank.

Allocated to “Orcas P & L” on Ecology’s schedule, filed as consumer-owned utility. A utility cannot sell these allowances to another company: it uses them for compliance, banks them, transfers them to an eligible generator, or consigns them to a quarterly auction, and the proceeds must go back to customers.

Clean-energy obligation assertions (pipeline/config/crosswalks/clean_energy_obligations.csv)

Washington State Legislature (RCW 19.405, RCW 19.285), Washington Utilities and Transportation Commission orders and docket filings, Washington State Department of Commerce EIA and CEIP report summaries, and each utility's own filings, cited per row

One assertion per row, five kinds kept apart: what applies, what is owed, what the utility filed, what the issuing body decided, and the open proceeding. A fuel-mix value is not a compliance verdict, and a filing that restates a target does not enact it; standing on each row says whose figure it is. An absent row states what was checked and when; a utility not in the file has not been curated.
