## Data quality

- The project was initially designed and permitted at approximately 124 MW with a maximum proposed count of 33 turbines. The operating EIA record reports 111.8 MW with 24 turbines. These are different development-stage descriptions of the same exact Bluestone facility, reflecting design optimization and permitting refinements. Northland acquired Bluestone through a transaction with Calpine in July 2020. The reported approximately C$5.6 million value relates to a multi-project portfolio transaction and should not be treated as Bluestone-only sale consideration. The regulatory record documents a design reduction from 33 to 27 turbines during permitting; the operating record later reports 24 turbines. No separate post-operation expansion, retirement, or repowering event is documented. The sole ownership of Bluestone Wind, LLC by Northland Power was confirmed in regulatory filings and is supported by the transfer history. Northland retained 100% ownership and operational control following the Calpine acquisition and subsequent intra-corporate restructurings.
