A conversation with Jason Clark, former chief strategy officer for American Clean Power

With the election approaching, I wanted to talk to the smartest person I could find to explain how the election could affect the Inflation Reduction Act and ultimately renewable energy development. So I hit up Jason Clark, who was until recently chief strategy officer for American Clean Power during passage of the Inflation Reduction Act and the first years of IRS guidance.
Clark, who has started energy policy consulting firm Power Brief, put together a risk profile for every major IRA program in the event of unified Republican control in Washington. I talked to him about the risk analysis, what programs are most at risk, and whether we should care about oil companies supporting some parts of the law.
Why did you do this?
I spent the last six months traveling the world and during that time, I was blissfully tuned out on politics. Now that I’m back in D.C., and given how consequential this election is going to be – suffice it to say, I’m tuned back in.
I was close to the IRA drafting process – I’m familiar with the underlying bill and also how the government thinks about the programs. I recently started a company, Power Brief, that marries my love for clean energy policy and my old consulting habits: pretty visuals and PowerPoints. And looking at what might happen to the IRA felt like THE big thing happening in the space right now, so I wanted to dive deeper.
A lot of the content has been “will they/won’t they” analysis. How much do Republicans feel strongly about this bill overall? How much passion would Trump have for pushing for a full repeal? It’s been out there. But this is so complicated and has so many moving parts. I wanted to try and capture both the political reality for some of these programs and also the very practical reality of how the government thinks about the cost of these programs. The fact it can all be contained in one visual is to help people who care about climate policy and want to really understand what may happen depending on how the election turns out.
We know Congress is going to take a stab at a new tax bill next year. I’ve written about how the IRA would be targeted in that situation. Can you help our readers understand why these programs would be vulnerable in tax talks?
Classic partisan politics in D.C. By the nature of using reconciliation, the IRA was ultimately purely Democratic-led and that automatically paints it with a certain color. I think that [former] President Trump has been very unshy about criticizing the IRA, and when he doesn’t use the IRA moniker, he uses different monikers thereof. And people are going to be looking for the easiest path [to money to extend the Trump-era tax cuts].
What I don’t think is that it’ll be thrown out entirely. We’ve seen members of the House and Senate express support for parts of it–
Republicans?
Correct. There was a letter from 18 House Republicans to the [House] Speaker [Mike Johnson] saying we shouldn’t just throw this out, we should really look at it. And I think that there’s a lot of people who look at where the investment from the IRA is flowing – a lot of the dollars are going to Republican-controlled states and districts. Yes, that may insulate the whole bill from repeal outright but a lot of that is announced investment but hasn’t turned into steel on the ground and jobs yet.
So your chart singles out EV tax credits as most vulnerable to repeal. Why?
The universe of electric vehicle tax credits is fully at risk. We’ve seen it from Republican voters – constituents! – who feel that EVs are just some type of government mandated, this is some car you have to buy. But it also happens to be very, very expensive. When the Joint Committee on Taxation (JCT} crunches the numbers about what this is going to cost between now and 10 years from now, it’s one of the most expensive portions of the legislation. So when you look at it and ask how much is it going to cost to ax this and give us the most savings in the tax code? You get this.
The IRA didn’t create these credits though. It simply expanded them. You think the entire credit could go away in a Republican trifecta?
I think the entire EV tax credit.
Okay. So next up on the chopping block per your chart is the renewable energy investment tax credit, or ITC. Why?
“Both the ITC and the PTC [production tax credit] when they shift into this new tech neutral paradigm have the same risk profile. For these, I don’t think it’s necessarily going to be a full repeal. I think the data about how much money is going into Republican districts is legitimate, and I think it will materialize. But there’s many spectrums of levers that someone can pull.
The tech neutral credit doesn’t end on a certain calendar year date. It ends when the U.S. sector hits a certain emissions target. The credit continues until that moment in time. One way to make the credit look less expensive on paper is to say, no, we are going to end it at a certain point. Take 2030 or 2032. You could codify a timeline on it, so the JCT won’t score the out-years on how expensive the credit is going to be. That is one version of it.
Another version of it is that there’s a base credit and then there’s added layers, like wage requirements or low-income area benefits. And that’s another thing you could pull to say, look, we’re not going to do that anymore.
What would be the impact on developers?
I don’t think a lot of folks appreciate just how long range some of this planning is, how long it takes to permit something, how long it takes to figure out the interconnection queue.
Companies aren’t thinking what are we going to build this year – they’re thinking what will be put online in 2035. So if the government changes the stability of that, companies start to pull back and say hey, let’s not go too crazy in the outyears. Baseline? It means fewer clean energy projects come online. The industry has been banking on a certain level of certainty to plan against. Any shockwave against that and some companies are going to look and ask if they have the assurance to move forward with this or not.
Okay well, candidly, to that I say: woof. So okay, your chart labels the PTC and energy efficiency credits as vulnerable. Why are they at risk if they cost less than other programs?
There are going to be certain things where the dollars and cents lose out to the political policy realities. On energy efficiency, it would be easy to make that whole category a continuation over the fight on gas stoves or heat pumps and frame them as tax credits for wealthy people to do expensive stuff on their homes, costing the rest of the country. I don’t think it’s as much of a kitchen table conversation per se but it’s up there. Even if it doesn’t save them that much money, it does face the risk of being that low-hanging fruit.
Well, alrighty then. What about 45X? That’s pretty crucial to many manufacturers out there today.
I think both Democrats and Republicans can stand behind more domestic manufacturing coming to the United States. That’s something that is a bipartisan consensus and reducing that, harming that, will pose a liability for politicians. Now similarly, you could shorten the window and amounts, but at the end of the day, it’s a lot more politically resilient despite being seen as the most expensive part of what was included in the IRA.
You ranked about half of the IRA’s programs – hydrogen, carbon capture, sustainable aviation fuels, and more – as being both low cost and at low risk for repeal. Why?
What they benefit from is a greater resonance with Republican policymakers. Carbon capture and sequestration, sustainable aviation fuels and biofuels, hydrogen – all of these things get more of a shrug with Republicans when you talk to them. And that is why you see major oil and gas groups come out and say, hey, let’s not repeal the whole IRA.
But repealing the programs at risk while keeping these other programs… how would that outcome impact the pace of decarbonization?
Drastically. It would effectively remove the economic premise for all future renewable energy generation. It gets rid of a key driver of the shift toward electric vehicles. I think if you repealed everything in the red, then I think what you’ve done is you’ve gotten rid of all the reasons capital is pouring money into renewable energy projects and storage right now. In that scenario you’d see a drastic slowdown in climate ambitions in the electric power sector and also the EV transition that’s been happening.
So… the oil companies telling Trump to keep some of the IRA is a cold comfort, then?
Knowing it doesn’t go away fully is a cold comfort looking at this risk analysis.
What did this exercise teach you about the IRA?
I think that a lot of the net benefit of the decarbonization that translates to jobs and economic development is really, really close, and a lot of what is in the IRA would be lower risk if more of that had been pushed through faster. I think implementation and the natural barriers of the lack of transmission, siting and permitting challenges… There's a confluence of things that make it hard to quickly double the size of the sector but a lot of stuff is coming. But there’s capital behind it, plans behind it, and I think they’re going to build a lot more. As they do that, the sentiment is going to change behind it, but we have to get to that promised land first.

What happens when one of energy’s oldest bottlenecks meets its newest demand driver?
Often the biggest impediment to building renewable energy projects or data center infrastructure isn’t getting government approvals, it’s overcoming local opposition. When it comes to the transmission that connects energy to the grid, however, companies and politicians of all stripes are used to being most concerned about those at the top – the politicians and regulators at every level who can’t seem to get their acts together.
What will happen when the fiery fights on each end of the wire meet the broken, unplanned spaghetti monster of grid development our country struggles with today? Nothing great.
The transmission fights of the data center boom have only just begun. Utilities will have to spend lots of money on getting energy from Point A to Point B – at least $500 billion over the next five years, to be precise. That’s according to a survey of earnings information published by think tank Power Lines on Tuesday, which found roughly half of all utility infrastructure spending will go toward the grid.
But big wires aren’t very popular. When Heatmap polled various types of energy projects last September, we found that self-identified Democrats and Republicans were mostly neutral on large-scale power lines. Independent voters, though? Transmission was their second least preferred technology, ranking below only coal power.
Making matters far more complex, grid planning is spread out across decision-makers. At the regional level, governance is split into 10 areas overseen by regional transmission organizations, known as RTOs, or independent system operators, known as ISOs. RTOs and ISOs plan transmission projects, often proposing infrastructure to keep the grid resilient and functional. These bodies are also tasked with planning the future of their own grids, or at least they are supposed to – many observers have decried RTOs and ISOs as outmoded and slow to respond. Utilities and electricity co-ops also do this planning at various scales. And each of these bodies must navigate federal regulators and permitting processes, utility commissions for each state they touch, on top of the usual raft of local authorities.
The mid-Atlantic region is overseen by PJM Interconnection, a body now under pressure from state governors in the territory to ensure the data center boom doesn’t unnecessarily drive up costs for consumers. The irony, though, is that these governors are going to be under incredible pressure to have their states act against individual transmission projects in ways that will eventually undercut affordability.
Virginia, for instance – known now as Data Center Alley – is flanked by states that are politically diverse. West Virginia is now a Republican stronghold, but was long a Democratic bastion. Maryland had a Republican governor only a few years ago. Virginia and Pennsylvania regularly change party control. These dynamics are among the many drivers behind the opposition against the Piedmont Reliability Project, which would run from a nuclear plant in Pennsylvania to northern Virginia, cutting across spans of Maryland farmland ripe for land use conflict. The timeline for this project is currently unclear due to administrative delays.
Another major fight is brewing with NextEra’s Mid-Atlantic Resiliency Link, or MARL project. Spanning four states – and therefore four utility commissions – the MARL was approved by PJM Interconnection to meet rising electricity demand across West Virginia, Virginia, Maryland and Pennsylvania. It still requires approval from each state utility commission, however. Potentially affected residents in West Virginia are hopping mad about the project, and state Democratic lawmakers are urging the utility commission to reject it.
In West Virginia, as well as Virginia and Maryland, NextEra has applied for a certificate of public convenience and necessity to build the MARL project, a permit that opponents have claimed would grant it the authority to exercise eminent domain. (NextEra has said it will do what it can to work well with landowners. The company did not respond to a request for comment.)
“The biggest problem facing transmission is that there’s so many problems facing transmission,” said Liza Reed, director of climate and energy at the Niskanen Center, a policy think tank. “You have multiple layers of approval you have to go through for a line that is going to provide broader benefits in reliability and resilience across the system.”
Hyperlocal fracases certainly do matter. Reed explained to me that “often folks who are approving the line at the state or local level are looking at the benefits they’re receiving – and that’s one of the barriers transmission can have.” That is, when one state utility commission looks at a power line project, they’re essentially forced to evaluate the costs and benefits from just a portion of it.
She pointed to the example of a Transource line proposed by PJM almost 10 years ago to send excess capacity from Pennsylvania to Maryland. It wasn’t delayed by protests over the line itself – the Pennsylvania Public Utilities Commission opposed the project because it thought the result would be net higher electricity bills for folks in the Keystone State. That’s despite whatever benefits would come from selling the electricity to Maryland and consumer benefits for their southern neighbors. The lesson: Whoever feels they’re getting the raw end of the line will likely try to stop it, and there’s little to nothing anyone else can do to stop them.
These hyperlocal fears about projects with broader regional benefits can be easy targets for conservation-focused environmental advocates. Not only could they take your land, the argument goes, they’re also branching out to states with dirtier forms of energy that could pollute your air.
“We do need more energy infrastructure to move renewable energy,” said Julie Bolthouse, director of land use for the Virginia conservation group Piedmont Environmental Council, after I asked her why she’s opposing lots of the transmission in Virginia. “This is pulling away from that investment. This is eating up all of our utility funding. All of our money is going to these massive transmission lines to give this incredible amount of power to data centers in Virginia when it could be used to invest in solar, to invest in transmission for renewables we can use. Instead it’s delivering gas and coal from West Virginia and the Ohio River Valley.”
Daniel Palken of Arnold Ventures, who previously worked on major pieces of transmission reform legislation in the U.S. Senate, said when asked if local opposition was a bigger problem than macro permitting issues: “I do not think local opposition is the main thing holding up transmission.”
But then he texted me to clarify. “What’s unique about transmission is that in order for local opposition to even matter, there has to be a functional planning process that gets transmission lines to the starting line. And right now, only about half the country has functional regional planning, and none of the country has functional interregional planning.”
It’s challenging to fathom a solution to such a fragmented, nauseating puzzle. One solution could be in Congress, where climate hawks and transmission reform champions want to empower the Federal Energy Regulatory Commission to have primacy over transmission line approvals, as it has over gas pipelines. This would at the very least contain any conflicts over transmission lines to one deciding body.
“It’s an old saw: Depending on the issue, I’ll tell you that I’m supportive of states’ rights,” Representative Sean Casten told me last December. “[I]t makes no sense that if you want to build a gas pipeline across multiple states in the U.S., you go to FERC and they are the sole permitting authority and they decide whether or not you get a permit. If you go to the same corridor and build an electric transmission that has less to worry about because there’s no chance of leaks, you have a different permitting body every time you cross a state line.”
Another solution could come from the tech sector thinking fast on its feet. Google for example is investing in “advanced” transmission projects like reconductoring, which the company says will allow it to increase the capacity of existing power lines. Microsoft is also experimenting with smaller superconductor lines they claim deliver the same amount of power than traditional wires.
But this space is evolving and in its infancy. “Getting into the business of transmission development is very complicated and takes a lot of time. That’s why we’ve seen data centers trying a lot of different tactics,” Reed said. “I think there’s a lot of interest, but turning that into specific projects and solutions is still to come. I think it’s also made harder by how highly local these decisions are.”
Plus more of the week’s biggest development fights.
1. Franklin County, Maine – The fate of the first statewide data center ban hinges on whether a governor running for a Democratic Senate nomination is willing to veto over a single town’s project.
2. Jerome County, Idaho – The county home to the now-defunct Lava Ridge wind farm just restricted solar energy, too.
3. Shelby County, Tennessee - The NAACP has joined with environmentalists to sue one of Elon Musk’s data centers in Memphis, claiming it is illegally operating more than two dozen gas turbines.
4. Richland County, Ohio - This Ohio county is going to vote in a few weeks on a ballot initiative that would overturn its solar and wind ban. I am less optimistic about it than many other energy nerds I’ve seen chattering the past week.
5. Racine County, Wisconsin – I close this week’s Hotspots with a bonus request: Please listen to this data center noise.
A chat with Scott Blalock of Australian energy company Wärtsilä.
This week’s conversation is with Scott Blalock of Australian energy company Wärtsilä. I spoke with Blalock this week amidst my reporting on transmission after getting an email asking whether I understood that data centers don’t really know how much battery storage they need. Upon hearing this, I realized I didn’t even really understand how data centers – still a novel phenomenon to me – were incorporating large-scale battery storage at all. How does that work when AI power demand can be so dynamic?
Blalock helped me realize that in some ways, it’s more of the same, and in others, it’s a whole new ballgame.
The following chat was lightly edited for clarity.
So help me understand how the battery storage side of your business is changing due to the rise in data center development.
We’re really in the early stages for energy storage. The boom is really in generation – batteries aren’t generators. They store, they shift, they smooth power, but they don’t generate the power from fuel. In this boom right now, everyone is trying to find either grid connections or on-site power generation. Those are the longest lead time items – they take a while – so we’re still in the early stages of those types of projects coming back and saying, we need to start procuring batteries. We need to start looking at the controls and how everything’s going to work together. That’s still a little bit in the future.
Are you seeing people deploy batteries responsibly, in an integrated way, or is it people unsure what they need?
There’s definitely uncertainty as to what they need. The requirements are still hard to nail down. A lot of the requirements come from the load curve of the AI workloads they’re doing, and that’s still a bit of a moving target. It’s the importance of knowing the whole system and planning that out in the modeling space.
The biggest space of all this is the load profile. Without a load profile, there’s uncertainty about what you’re going to need –
When you say load profile, what do you mean?
The AI workload. The GPUs. The volatility. In a synchronized training load, all of the GPUs are generally doing the same thing at the same time. They all reach a pause state at the same time, and you’re close to full power on the data center, and then they say, okay now we go idle. It has a little bit of a wait and then starts back up again.
It’s that square wave, very sharp changes in power – that’s the new challenge of an AI data center. That’s one of the new uses of BESS that’s being added compared to the traditional data center doing data storage. They’re more stable which use less power and are more stable.
The volatility is where some of the friction comes in, and that has to be handled by some technology.
So what you’re telling me is that data center developers do not know how much they need in terms of battery storage? Simply put, they don’t know how much power they need?
Traditionally, utility-scale batteries – the projects we’ve been doing – come from a PPA, an interconnect agreement. There’s something in place where they know exactly how many batteries they can install. They know how many megawatts they’re allowed to install. Then they come to us and they say, I need a 4-megawatt battery for two hours. Tell me how many batteries you’re going to give me.
In a data center, they don’t know that first number. They don’t know how many megawatts they need. So that’s the first question: well, how big of a battery do you need?
If you have a 1-gigawatt data center that means the load change is 60% of that – 600 megawatts is the step up-and-down. The starting point is 600 megawatts for two hours. That’s the starting point that’ll cover being able to take care of that volatility. The duration is a part of it, too. From there you get into more detailed studies.
When it comes to transmission, how much of a factor is it in how much storage a data center needs?
The first thing is whether it’s connected at all. The battery is a shock absorber for the whole system. If you are grid-connected, the BESS is still a stability asset – it’s still improving the power quality and stability at an interconnect. If you’re doing on-site generation, it becomes vital because you have only one system being controlled.
As far as when you talk about permitting and transmission, the details of that don’t really play that much into the BESS, but it’s tangentially related. The BESS is an important part of how you handle that situation. Whether you get to interconnect or not, it’s an extremely important asset in that mix.
With respect to the overall social license conversation, how does battery storage fit into the conversations around energy bills and strain on the grid?
Bias aside, I think it’s the most important piece.
If you look at the macro scale, it’s like transitioning to renewables where they’re intermittent; batteries turn intermittent generation from renewables into firm, dispatchable power. It’s still not going to be available all the time – you’re not going to turn a solar plant into a 24-hour baseload plant – but a battery allows you to shift the energy. It greatly alleviates the problem.
The other aspect is it’s a stability asset. The short version of that is you have big thermal plants – rotating metal masses that have momentum to them that stabilize everything on the grid. As you take those offline, the coal plants and the gas plants, the grid itself loses that inertia so it is more susceptible to spikes and failures because of small events. Batteries are able to synthesize that inertia.
