The end may be in sight, but it’s not here yet.
Are interest rates going to go down? The market will have to wait.
Following a Tuesday report showing steady consumer prices in May and prices overall only rising 3.3% in the past year, the Federal Reserve held steady on interest rates, releasing a projection Wednesday showing just one rate cut this year.
If rates do indeed fall this year (or next, when the Fed is projecting four cuts), that would be a big relief to renewable developers. There’s been an unprecedented flow of money into the sector in the past few years — whether from tax credits from the Inflation Reduction Act or power purchase agreements from utilities and corporations that want to decarbonize, you name it — but it’s come at the same time as projects have gotten more expensive to undertake. That’s in terms of labor and supplies, but also the most important part of any project: money.
“In the near term, investors are looking for market rates to fall to reduce financing costs — the Fed cutting the base rate could greatly help this along,” Srinivasan Santhakumar, senior research analyst at Wood Mackenzie, told me in an email.
Interest rates don’t affect every project equally. Renewables tend to be capital intensive, meaning that a higher portion of their costs are in building them as opposed to operating them. For an offshore wind turbine project, almost 70% of the expenditure comes from capital, whereas with a combined-cycle natural gas turbine plant it’s less than 20%, according to Wood Mackenzie data.
That’s because, in the case of wind and solar, the “fuel” is free, unlike with natural gas and other fossil-based energy sources. This means that developers have to fund more of the project upfront with borrowed money, which means a bigger hit from higher interest rates. According to an analysis by the investment bank Lazard, when the cost of debt is 5%, the levelized cost of an offshore wind project is $88 per megawatt-hour; when the cost of debt rises to 8%, the levelized cost rises to $118. For a combined cycle gas plant, the levelized cost per megawatt-hour rises from $66 to just $76.
“You’re really sensitive to interest rates” as a renewable developer, as Tim Latimer, the chief executive officer of the geothermal startup Fervo, explained to me. “That’s a big investment up front.”
In some sense, renewables economics have been a victim of their own success, Latimer said. Because there are lots of buyers for 15 years’ worth of renewable electricity and no risk of fuel costs surging or falling dramatically, the “spread” that renewable projects demand over risk-free rates is much smaller than for natural gas projects. But that means as rates rise, the spread shrinks more with renewables. “That has a much bigger relative impact on the economics,” Latimer said.
Geothermal projects have similar economics to other renewables, Latimer said, and being able to sell power to offtakers has helped protect the finances of Fervo’s projects.
Democratic Senators Sheldon Whitehouse and Elizabeth Warren have pressed Federal Reserve chair Jerome Powell on the high rates, citing the effect on renewable investments. “Your decision to rapidly raise interest rates beginning in 2022, and the potential that they may remain too high for too long, has halted advances in deploying renewable energy technologies and delayed significant climate and economic benefits from these projects,” the two wrote in a letter to Powell in March.
Executives from some of the world’s biggest renewables companies have been singing this song, as well. “Renewable energy in general is very, very susceptible to rising interest rates and offshore wind, even the most of all of the renewable energy sectors because it's so capital intensive. Our fuel is free, we say, but our fuel is really the cost of capital because we put so much capital out upfront,” Orsted Americas chief executive officer David Hardy told Bloomberg.
In a May earnings call, Orsted’s global chief executive, Mads Nipper, told investors, “It’s impossible to say whether [costs] have peaked yet, and on the way down, as that will hinge, very much, on the macroeconomic factors, and the rates, specifically.”
The premium renewables can yield over government debt has shrunk dramatically since 2020, BloombergNEF analyst Atin Jain said. In response, developers have increased prices for power purchase agreements, knowing that they can do so thanks to the demand for their clean electrons. But that also means more expensive power when the deals are struck, and in the case of several offshore wind projects in the Northeast, price increases can sometimes mean the deals never get done at all, even in spite of generous IRA tax credits.
“Higher interest rates are driving up project costs and [power purchase agreement] costs as well,” explained Michael Arndt, the president of Recurrent Energy, at a forum hosted by the American Council on Renewable Energy. “Being able to bring in more tax equity is a big offset to a higher interest rate environment.”
According to BNEF data, developers have tried to shorten the term of their borrowing, aiming to avoid getting locked into higher rates for a long time, while also going to the bond market for financing as opposed to bank loans, which typically means paying a lower rate. This then advantages longer tenured and more established developers who are better able to access the bond market. As Esper Nemi, the chief financial officer of the green energy giant Brookfield Renewable Partners, said in a May earnings call, “Our access to scale capital means we can execute on large opportunities where there are fewer viable partners and risk adjusted returns can therefore be very attractive.”
“Where possible, if you’re a creditworthy issuer and you’re more financially stable and have the ability to make regular interest payments, you have been viewed attractively by the bond market,” Jain told me. Bond issuance by utilities and renewable developers has more than doubled since before the pandemic, according to BNEF data. “That’s how people are navigating this environment: cutting loan tenors, doubling down on bonds. Everyone is hoping that though they have to tap more expensive debt now they’ll be able to refinance those loans,” Jain said.
How many people will be able refinance remains to be seen. “Developers with deeper balance sheets are able to navigate this a little bit better than smaller or midsize companies,” Jain added.
Latimer said that higher rates could be particularly challenging to first of a kind projects. Investors have a return they want a new project to generate and that figure moves up with interest rates.
“The return hurdle that you need to hit to entice capital that views your project as a new development and new technology moves up with interest rates,” Latimer told me. “Your project economics have to be that much better relative to what your baseline was before because everyone has higher return expectations.”

A conversation with VDE Americas CEO Brian Grenko.
This week’s Q&A is about hail. Last week, we explained how and why hail storm damage in Texas may have helped galvanize opposition to renewable energy there. So I decided to reach out to Brian Grenko, CEO of renewables engineering advisory firm VDE Americas, to talk about how developers can make sure their projects are not only resistant to hail but also prevent that sort of pushback.
The following conversation has been lightly edited for clarity.
Hiya Brian. So why’d you get into the hail issue?
Obviously solar panels are made with glass that can allow the sunlight to come through. People have to remember that when you install a project, you’re financing it for 35 to 40 years. While the odds of you getting significant hail in California or Arizona are low, it happens a lot throughout the country. And if you think about some of these large projects, they may be in the middle of nowhere, but they are taking hundreds if not thousands of acres of land in some cases. So the chances of them encountering large hail over that lifespan is pretty significant.
We partnered with one of the country’s foremost experts on hail and developed a really interesting technology that can digest radar data and tell folks if they’re developing a project what the [likelihood] will be if there’s significant hail.
Solar panels can withstand one-inch hail – a golfball size – but once you get over two inches, that’s when hail starts breaking solar panels. So it’s important to understand, first and foremost, if you’re developing a project, you need to know the frequency of those events. Once you know that, you need to start thinking about how to design a system to mitigate that risk.
The government agencies that look over land use, how do they handle this particular issue? Are there regulations in place to deal with hail risk?
The regulatory aspects still to consider are about land use. There are authorities with jurisdiction at the federal, state, and local level. Usually, it starts with the local level and with a use permit – a conditional use permit. The developer goes in front of the township or the city or the county, whoever has jurisdiction of wherever the property is going to go. That’s where it gets political.
To answer your question about hail, I don’t know if any of the [authority having jurisdictions] really care about hail. There are folks out there that don’t like solar because it’s an eyesore. I respect that – I don’t agree with that, per se, but I understand and appreciate it. There’s folks with an agenda that just don’t want solar.
So okay, how can developers approach hail risk in a way that makes communities more comfortable?
The bad news is that solar panels use a lot of glass. They take up a lot of land. If you have hail dropping from the sky, that’s a risk.
The good news is that you can design a system to be resilient to that. Even in places like Texas, where you get large hail, preparing can mean the difference between a project that is destroyed and a project that isn’t. We did a case study about a project in the East Texas area called Fighting Jays that had catastrophic damage. We’re very familiar with the area, we work with a lot of clients, and we found three other projects within a five-mile radius that all had minimal damage. That simple decision [to be ready for when storms hit] can make the complete difference.
And more of the week’s big fights around renewable energy.
1. Long Island, New York – We saw the face of the resistance to the war on renewable energy in the Big Apple this week, as protestors rallied in support of offshore wind for a change.
2. Elsewhere on Long Island – The city of Glen Cove is on the verge of being the next New York City-area community with a battery storage ban, discussing this week whether to ban BESS for at least one year amid fire fears.
3. Garrett County, Maryland – Fight readers tell me they’d like to hear a piece of good news for once, so here’s this: A 300-megawatt solar project proposed by REV Solar in rural Maryland appears to be moving forward without a hitch.
4. Stark County, Ohio – The Ohio Public Siting Board rejected Samsung C&T’s Stark Solar project, citing “consistent opposition to the project from each of the local government entities and their impacted constituents.”
5. Ingham County, Michigan – GOP lawmakers in the Michigan State Capitol are advancing legislation to undo the state’s permitting primacy law, which allows developers to evade municipalities that deny projects on unreasonable grounds. It’s unlikely the legislation will become law.
6. Churchill County, Nevada – Commissioners have upheld the special use permit for the Redwood Materials battery storage project we told you about last week.
Long Islanders, meanwhile, are showing up in support of offshore wind, and more in this week’s edition of The Fight.
Local renewables restrictions are on the rise in the Hawkeye State – and it might have something to do with carbon pipelines.
Iowa’s known as a renewables growth area, producing more wind energy than any other state and offering ample acreage for utility-scale solar development. This has happened despite the fact that Iowa, like Ohio, is home to many large agricultural facilities – a trait that has often fomented conflict over specific projects. Iowa has defied this logic in part because the state was very early to renewables, enacting a state portfolio standard in 1983, signed into law by a Republican governor.
But something else is now on the rise: Counties are passing anti-renewables moratoria and ordinances restricting solar and wind energy development. We analyzed Heatmap Pro data on local laws and found a rise in local restrictions starting in 2021, leading to nearly 20 of the state’s 99 counties – about one fifth – having some form of restrictive ordinance on solar, wind or battery storage.
What is sparking this hostility? Some of it might be counties following the partisan trend, as renewable energy has struggled in hyper-conservative spots in the U.S. But it may also have to do with an outsized focus on land use rights and energy development that emerged from the conflict over carbon pipelines, which has intensified opposition to any usage of eminent domain for energy development.
The central node of this tension is the Summit Carbon Solutions CO2 pipeline. As we explained in a previous edition of The Fight, the carbon transportation network would cross five states, and has galvanized rural opposition against it. Last November, I predicted the Summit pipeline would have an easier time under Trump because of his circle’s support for oil and gas, as well as the placement of former North Dakota Governor Doug Burgum as interior secretary, as Burgum was a major Summit supporter.
Admittedly, this prediction has turned out to be incorrect – but it had nothing to do with Trump. Instead, Summit is now stalled because grassroots opposition to the pipeline quickly mobilized to pressure regulators in states the pipeline is proposed to traverse. They’re aiming to deny the company permits and lobbying state legislatures to pass bills banning the use of eminent domain for carbon pipelines. One of those states is South Dakota, where the governor last month signed an eminent domain ban for CO2 pipelines. On Thursday, South Dakota regulators denied key permits for the pipeline for the third time in a row.
Another place where the Summit opposition is working furiously: Iowa, where opposition to the CO2 pipeline network is so intense that it became an issue in the 2020 presidential primary. Regulators in the state have been more willing to greenlight permits for the project, but grassroots activists have pressured many counties into some form of opposition.
The same counties with CO2 pipeline moratoria have enacted bans or land use restrictions on developing various forms of renewables, too. Like Kossuth County, which passed a resolution decrying the use of eminent domain to construct the Summit pipeline – and then three months later enacted a moratorium on utility-scale solar.
I asked Jessica Manzour, a conservation program associate with Sierra Club fighting the Summit pipeline, about this phenomenon earlier this week. She told me that some counties are opposing CO2 pipelines and then suddenly tacking on or pivoting to renewables next. In other cases, counties with a burgeoning opposition to renewables take up the pipeline cause, too. In either case, this general frustration with energy companies developing large plots of land is kicking up dust in places that previously may have had a much lower opposition risk.
“We painted a roadmap with this Summit fight,” said Jess Manzour, a campaigner with Sierra Club involved in organizing opposition to the pipeline at the grassroots level, who said zealous anti-renewables activists and officials are in some cases lumping these items together under a broad umbrella. ”I don’t know if it’s the people pushing for these ordinances, rather than people taking advantage of the situation.”
