Powerstack: Post-IPO, Fervo competes on power price

Hi there,

Fervo IPO'd yesterday. Now, it's got $1.89bn and a cost curve to hit. Here's what to watch.

This is Sightline’s weekly newsletter on the moves and motives shaping the load growth era. Not a client yet?

Fervo Energy IPO’d yesterday. As an analyst watching this sector since 2007, I legit never thought I’d see something like this. Wild. Huge congrats to Tim, Jack, and team for carrying it to this point.

On its first day of trading, the price went from $27/share at open to $36.54 by market close. At that, and the 70m shares in the float, Fervo raised $1.89bn, with a market cap of ~$10bn. This puts it about $2bn ahead of Ormat, and makes it the most valuable pure-play geothermal company in the world.

Sightline clients, take a minute and go read our deeper coverage on the IPO and what’s next for Fervo here.

Ahead of the IPO, reading the S-1 got me thinking:

Is the price Fervo is getting for its power competitive?

If we look just at just the most recent geothermal PPAs, maybe not. 

The only publicly-available datapoints we have for Fervo’s offtake price are:

And given the PPA for Corsac in Nevada is for delivery in 2030, we can reasonably assume there will be some learning by that time, and the all-in cost of its first projects at Cape Station in Utah are coming in a fair bit higher, especially given the $7m/MW overnight cost listed in the S-1.

Since 2010 in the US there have been just seven new geothermal projects (all conventional geo) with prices available in the public record, averaging about 24MW each. PPAs for these projects come in at $67-96/MWh, and average $82/MWh.

If we look at PPA renewals – ie, projects commissioned before 2010 but whose PPAs expired and have since renewed – we get 12 projects with available pricing, ranging from $69-86/MWh, averaging $76/MWh. The most recent is Ormat’s Heber 1 renewal that hit $86/MWh for a 25-year extension for an already 30-year-old plant (we wrote about this here).

So if we’re just looking at the $21/MWh delta between Fervo’s next-gen EGS at Corsac, and Ormat’s renewal at Heber 1, Fervo’s power price is not all that competitive.

But we’re not looking at just that.

If we widen our aperture to the broader market context, $107/MWh for clean firm power starts to look quite competitive indeed. Consider the following:

1. Regulated demand. In 2021, California's CPUC ordered utilities in the state to procure 1GW of clean firm power by 2028. Southern California Edison's share is ~350MW. To cover this, it contracted 320MW with Fervo across two PPAs for nearly all of it. The CPUC’s own watchdog group filed a complaint, saying the price was too high, but CPUC still sided with SCE. While not public, the resolution stated that the Fervo bids were the lowest geothermal prices in the solicitation.

My question is whether it was the only bid in the solicitation – US geothermal added almost no new capacity through the 2010s, so the odds of a competing bid were low. Fervo likely set the price because it was the only viable seller.

2. Hyperscaler demand. Fervo is kinda competing with other geothermal, and nuclear, but really it’s competing with gas. If a hyperscaler needs power and needs it soon, right now gas is the main option (see Powerstack last week about the PJM queue) – unless it hasn’t already locked up a turbine. In Sightline’s Fastest MW report, we’re putting turbine lead times past 34 months. Suddenly, Fervo’s timelines start to sound pretty good.

Constellation's Q1 2026 earnings deck from Monday showed it’s targeting $10-25/MWh premiums on long-term agreements for 1GW of new gas Powered Land deals (its direct-to-data-center product). While we don’t have an exact price, this premium is still a signal on where gas is clearing, from a seller incentivized to price it up. So on price, $107/MWh isn't an outlier against new gas in this market either. It appears Google read the gas market the same way, signing an ROFR on a chunk of Fervo’s development pipeline, up to 3GW, as outlined in the S-1.

3. Western expansion. One Saturday morning a few years ago, I had a go at totaling-up Fervo’s leases – I got to just over 200k acres, concentrated in Utah and Nevada. From the S-1 we finally learned that its holdings are 596,000 acres, which Fervo estimates is enough to support 38GW of long-term pipeline.

No other geothermal developer holds comparable Western acreage, and what Fervo holds sits in states where hyperscalers are building – maybe not the top markets, but data center development is happening there nonetheless (like deployments in Utah, that have become wildly controversial in the past week). And right now, $107/MWh is still competitive for clean firm in the region. Whether the next PPAs continue to be competitive depends on the S-1's overnight capital cost curve, $7m/MW today to $3m/MW at scale. That in turn depends on whether Cape Station performs operationally – if Fervo can officially get on the cost curve. But as of yesterday, Tim and Jack have $1.89bn of fresh IPO proceeds and 596k acres of leasehold to test that.

So if we zoom out, $107/MWh looks less like an expensive new EGS price and more like a price that’s in the game.

Geo’s going to be a niche for the foreseeable – but the niche has no limit. The limit does not exist. 🤓

If we look at our Fastest MW analysis, the fastest way to get power to the grid right now is solar+BESS with existing interconnection agreements in ERCOT. This setup gives a 27-month or less time-to-COD, and can come in at $40/MWh PPAs, a price and speed Fervo can't catch. So, per the above, the right way to think about it is that Fervo competes for a different customer than the ones looking at solar+BESS. Are they required to procure geo? Are they in the West? Do they need fully baseload power? For sure, that’s a smaller niche. But if Fervo's anticipated 38GW resource base materializes even a little, the niche is huge.

Looking ahead, I'm watching three things:

If the 2020s are the geothermal decade, 2026 is the year where we’ll see how far it can go.

A quick read on the numbers shaping the market. The capex, the contracts, the regs, all anchored in the so-what.

$250bn // DOE loan authority now explicitly available again, for nuclear, oil, gas, and grid-enhancing technologies under the revamped Energy Dominance Financing Program. The new guidance strips out any GHG requirements and community benefit plans, extends funding through FY2028, and adds a new track focused on retooling or repowering retired infrastructure. Targets include nuclear plant expansions, retired plant conversions, transmission upgrades, and critical minerals recovery. But it seems the LPO is open for business again. 

100MW // The minimum for Oregon's new dedicated data center rate class. Portland General Electric's large-load customers now pay for the full cost of the grid infrastructure they require, plus a surcharge above 100MW that funds energy efficiency upgrades for low-income households, as of June 10. Virginia's proposed data center rider covers similar cost-allocation ground, Georgia's CIR program is energy-only and voluntary. If other PUCs follow Oregon’s hard line, the all-in costs of data center siting shift.

$1bn // VoltaGrid's raise from Blackstone and Halliburton ($775m primary + $225m secondary), paired with its acquisition of key supplier Propell and a 7.5GW BtM order book. As the BtM power market gets more competitive, VoltaGrid is betting that owning Propell's equipment manufacturing locks in margins and delivery timelines. Plus, Blackstone brings infrastructure capital, and Halliburton brings oilfield logistics and a direct line to the gas supply chain.

£575m // Eon's agreed takeover of UK household energy supplier Ovo, creating a 9.6m-customer entity that will rival Octopus Energy for the top spot in the UK retail market. Consolidation in that market continues post-Ofgem's new capital adequacy rules, introduced after the 2021-2022 wholesale gas spike wiped out ~30 suppliers. Eon, British Gas, and Octopus will together serve nearly three-quarters of UK households.

2 // AP1000 units at V.C. Summer that Brookfield just partnered with The Nuclear Company to run. Brookfield won the development rights and immediately subcontracted project management to TNC, the team that finished Vogtle. V.C. Summer Units 2 and 3 in Jenkinsville, SC, are the most construction-ready nuclear opportunity in the US, with steel already in the ground, licensing history on file, and design locked in before abandonment in 2017. Santee Cooper has committed to a final investment decision package by 2028, no ratepayer funding.

14GW // Data center grid connection requests that triggered Denmark's grid operator to impose a 3-month moratorium. The total queue hit 60GW across all applicants -- renewables, power-to-X, EVs, and data centers all competing for the same constrained grid. The 14GW of data center requests alone is twice Denmark's entire peak load, which tells you most of it is speculative. Denmark is following the Netherlands and Ireland with this, but Ireland’s solve — 80% renewables, dispatchable backup, mandatory grid export for any new site over 10MW — looks attractive.

The policies, rulings, and company moves worth watching.

FERC Chairman Swett calling out PJM as "too big to function." At the country’s biggest grid operator’s annual meeting in Baltimore this week, FERC Chairman Laura Swett had harsh words for the grid operator, calling its stakeholder process "slow where it must be fast, opaque where it must be transparent." FERC is holding PJM’s feet to the fire as its December capacity auction came up short of its reserve margin target, demand forecasts are spiking on data center growth, and the RTO is under simultaneous pressure on interconnection reform, co-location rules, and competitive transmission. (PJM also released a new proposal to overhaul its capacity market.) Watch which side takes action first. 

AEP weighing exit from PJM and SPP over interconnection gridlock. On its Q1 earnings call, AEP CEO Bill Fehrman said the company is actively reviewing whether to leave PJM and SPP, stay in them, or pursue "alternative structures." It’s a big public statement from one of the country's largest vertically integrated utilities with 63GW of contracted large load coming online by 2030, and PJM's interconnection pace isn't moving fast enough to serve it.

BLM's new rule lets geothermal exploration skip NEPA on public lands. The Geothermal Exploration Categorical Exclusion allows geothermal exploration activities -- including temperature gradient wells, seismic drilling, core drilling, and associated road and pad construction -- on up to 10 acres to skirt the full onerous environmental review. It’s a meaningful unlock for the notoriously tricky exploration phase, where permitting friction has historically killed projects before they get started. 

EPA's proposal to allow pre-permit construction on "non-emitting" components at data centers and power plants. Developers would be able to break ground on utility infrastructure, concrete pads, and certain buildings before obtaining federal air permits, possibly cutting months off development. The proposal is still subject to public backlash and legal challenges.
