Ownership and offtake
ProOwnership and offtake are part of Pro
Owners and their shares, parent companies, and power purchase agreements with their buyers. EIA-860M lists RWE Clean Energy as the operator, which is not always the owner.
Modeled data
ProPro adds modeled values for this plant. Everything above stays free.
Modeled curtailment
A range, not one number. The lower bound counts hours inside the production tax credit window; the upper bound is the no-credit case.
Expected vs reported generation
Monthly modeled expected output and physical potential next to EIA-923 reported output.
