- Financing summary: PPM Energy's May 23, 2005 announcement estimated approximately $235 million of capital investment for the Shiloh project. The announcement did not disclose a debt, tax-equity, sale-leaseback, or other project-financing structure, and it did not state the acquisition consideration paid to enXco; therefore the $235 million estimate should not be treated as either a sale price or a financing amount. — PPM AND ENXCO ANNOUNCE 150 MW SHILOH WIND PROJECT - Avangrid · confidence: medium

## Data quality

- These records agree in 2006 operation but differ on the exact milestone month. The approximately $235 million figure is an estimated project capital investment announced by PPM, not disclosed acquisition consideration or a confirmed project-financing amount. Repowering references for Shiloh IV concern a separate 102.5 MW project and should not be attributed to Shiloh I. The current EIA record continues to show Shiloh I as one operational 150 MW unit. both names are retained with their stated roles.
