• Non-CAISO West: 5.8 GW (20 projects), driven by Western Area Power Administration (WAPA) requests across Arizona, Nevada, and California.

• MISO: 2.5 GW (6 projects), almost entirely a single unclassified tech type 2.2 GW Ameren Missouri request.

• Southeast: 2.5 GW (29 projects), from Duke Energy Carolinas’ latest cluster.

• By technology, gas led new requests (3.0 GW, 17 projects), followed by battery storage (2.4 GW).

Withdrawals: 4.85 GW (26 projects)

• Withdrawals were spread across the West, MISO, and the Southeast.

• West: 1.7 GW (5 projects), led by a 600 MW Idaho Power gas request.

• MISO: 1.3 GW (9 projects).

• Southeast: 0.9 GW (8 projects), split between Southern Company and Florida Power & Light.

• CAISO: 0.4 GW (1 project), a single wind withdrawal.

In the News

• FERC issues orders on large load interconnection. On June 18, FERC issued “Show Cause” orders to the six FERC-jurisdictional grid operators, requiring them to either demonstrate that their existing large load tariffs adequately serve large loads or revise them to address the issues the Commission identified. Each operator and its transmission owners have 60 days to respond, and within 30 days must file an informational report on how they will ensure adequate generation to serve existing and new large loads. The orders highlight five reform areas: more efficient transmission study and application processes; cost-shifting protections and cost transparency; accommodation of co-location and behind-the-meter generation; new transmission services for flexible large loads; and a process to study generation serving co-located and electrically proximate loads. The fifth reform area is one we will be watching as proposals come in, since study tracks for generation serving co-located load could create separate queue clusters/pathways to monitor and analyze.

• Virginia weighs making large loads pay up front for the transmission they trigger. In a Dominion transmission rate case, Virginia State Corporation Commission staff filed testimony on June 16 recommending that the cost of transmission lines and upgrades built to serve a single high-load customer be assigned directly to that customer rather than spread across the rate base. Staff would do this by modifying Dominion’s line-extension policy to recover those facilities through Contribution-in-Aid-of-Construction, meaning the triggering customer pays up front. The recommendation builds on the Commission’s 2025 biennial order, which directed Dominion to develop alternative ways to allocate transmission costs. As the largest data-center market in the country, whatever Virginia codifies may become a reference point beyond PJM.

• Amazon and Vistra take Texas co-location to a nuclear plant (Deep dive at the bottom of this issue). Comanche Peak Power Company and Amazon are seeking PUCT approval for a net metering arrangement that would place up to 1,200 MW of behind-the-meter data center load at the existing 2,400 MW Comanche Peak nuclear plant in Somervell County, under the same SB6 framework as the Crusoe-Goodnight case we covered last issue. The data center would install its own backup generation, sized to cover its full load and kept off the transmission grid, so that during an emergency the load runs on backup. The applicants go further, committing to making all of Comanche Peak’s capacity available to Security Constrained Economic Dispatch within 30 minutes of an ERCOT instruction. It is a notable contrast with co-location cases elsewhere, where data center developers have resisted curtailment, and could be a sign of hyperscalers making efforts to trade grid-friendly terms for a faster path online. More on this below.

• Gas turbine shortage tests PJM’s fast-track rules. Advanced Power Services, developer of the Chestnut Run gas project in Ohio, has asked FERC for a waiver to swap in lower-output turbines after manufacturing backlogs pushed its in-service date out by at least two years. The swap would trim the plant’s maximum output but let it hold close to its original online date. The catch is that PJM’s Reliability Resource Initiative, the shovel-ready fast track, bars changes to a project’s size or Capacity Interconnection Rights, so the substitution needs a waiver. PJM protested on June 18, arguing the request fails FERC’s waiver criteria and would hand Advanced Power an unfair edge over developers complying with the tariff, and noted the company could instead use the Expedited Interconnection Track FERC approved on June 9.

Activity Map

The main action this period is in the non-CAISO West and Southeast. New queue requests came in from the Southwest (WAPA), the Mountain/Pacific Northwest (Idaho Power, BPA, PacifiCorp, Black Hills Power), and a new cluster from Duke Energy Carolinas. Withdrawals were scattered, showing up across the Mountain West, the Upper Midwest in MISO, and the Southeast. There was also substantial GIA activity in SPP.

Queue Activity

This was a relatively quiet period for the queues, with additions, withdrawals, and newly operational activity all down from the prior period. The two-week totals come to just under 11 GW of new entries against 4.9 GW of withdrawals, a net addition of about 6 GW.

New entries were led by Duke Energy Carolinas, which added 28 projects totaling 2.5 GW across North and South Carolina, mostly battery storage (about 1.4 GW) and gas (roughly 0.7 GW). A WAPA Desert Southwest cluster of about 3.3 GW across eight projects in Arizona, Nevada, and California accounts for most of the West’s activity (a mix of gas, battery, and solar+storage). The single largest request is a 2.2 GW project from Ameren Missouri in MISO, which entered the queue seeking network resource service and sits in its application window. It has not yet been assigned a resource type in the MISO queue data, so it accounts for much of the “Other” capacity this period.

Withdrawals were broadly distributed, the largest being a 600 MW Idaho Power gas request and a 500 MW solar+storage project in SPP. Only four projects reached commercial operation this period, all small Florida and Georgia solar projects in the Southeast.

The standout metric this period is GIAs signed, up about 119%to 4.6 GW. Most of that is a cluster of Nebraska public-power gas units, from NPPD and OPPD, reaching interconnection agreements in SPP.

Queue Snapshot - Current State

The active queue stands at 1.80 TW across 8,366 projects, and is still overwhelmingly solar and battery by volume. Firm resources continue to gain share even after a relatively quiet couple of weeks for the queues, with gas up about 51 percent, nuclear up 81 percent, and geothermal up over 170 percent year-over-year, while battery, solar, and wind are each down by double digits. As we have noted before, the outsized swing in "Other" (up roughly 349 percent) is mostly unclassified new entries like this period's Ameren (MISO) request that have not yet been assigned a technology, so it overstates how much genuinely uncategorized capacity is entering the queue.

On net, the queue grew by about 6.1 GW this period.The non-CAISO West leads at +4.1 GW on the WAPA cluster, followed by the Southeast at +1.6 GW on Duke's Carolinas additions and MISO at +1.2 GW. Only two markets contracted, both marginally: CAISO at -400 MW on a single wind withdrawal and SPP at -422 MW. PJM, which dominated last period's withdrawals as it cleared its legacy serial queue, is quiet this time, with the reformed cluster process queue data still pending release.

Amazon vs Crusoe: A Test of Two Distinct ERCOT Co-location Strategies

We’ve recently covered two contrasting data center architectures for co-location in ERCOT.

On one hand, we have Crusoe: they are proposing to co-locate two large data center facilities, Crusoe One (265.5 MW) and Crusoe Two (260 MW), behind a single existing wind farm (the 265.5 MW GOODNIT1), with a second wind farm (GOODNIT2, expected commercial operation May 2027) planned to be added behind the same point of interconnection later.

Under ERCOT’s proposal, both Crusoe facilities would need to fully curtail (525.5 MW of firm AI load combined) in exchange for taking a 265.5 MW intermittent wind generator into the net metering arrangement. That’s a 2:1 ratio between curtailed firm load and removed intermittent generation.

It’s important to note the Crusoe facilities are co-located with intermittent wind power. This means these facilities cannot remain fully behind-the-meter. They regularly need to draw power from the ERCOT grid when wind output is below the facility’s demand. Secondly, based on testimony in this PUCT filing, they do not appear to have full backup generation readily deployable. We are inferring this from the harm argument in that testimony, where Crusoe’s expert argued the following about a 30-minute shutdown window:

“Abrupt, unplanned curtailment carries serious operational risks: cascading hardware failures across server clusters, corruption or loss of active computational work that cannot be recovered, data storage integrity failures, and thermal events caused by the sudden loss of coordinated cooling infrastructure. These are not hypothetical concerns - they are documented in this record.”

— Bojorquez Testimony, PUCT Docket 59220, Item 21, June 3, 2026

That does not paint a picture of a facility which has full, rapidly available backup generation on-site.

We contrast this against Amazon’s Comanche Peak filing (PUCT Docket 59399), widely reported as “Project Spectrum.” This is a recent proposal to co-locate a data center of up to 1.2 GW behind an existing 2.4 GW nuclear plant (Comanche Peak). This facility is planned to be fully behind the meter, with the load not expected to ever be served by grid power (per Amazon’s application in the docket). Also crucially, Amazon explicitly plans to establish sufficient backup generation on-site, sized “equal to or exceeding” the load’s expected demand, to power the entirety of their facility. For this reason, Amazon is preemptively offering the 30-minute mechanism directly in their application, rather than waiting to negotiate around ERCOT’s proposed conditions. However, their architecture grants them a convenient luxury which Crusoe seemingly does not share: they structure the guarantee as a return of Comanche Peak’s full capacity back to the grid, and not a shutdown of their facility. In the case of such an event, Amazon plans to simply switch to their fleet of on-site backup generators. Based on the testimony filed by Crusoe’s expert and referenced above, it appears that Crusoe does not expect to have this same capability.

It’s worth noting that under ERCOT’s proposed conditions, the backup gen must be sized to serve the full facility load, and not just enough to offset what the co-located generator was contributing behind the meter. So a developer co-locating a 1 GW facility with a 50 MW generator would need to build roughly 1 GW of backup, not 50 MW, if they want to remain operational through a grid emergency. The sizing requirement scales with the data center, and not with the co-located generator.

And here we see the pattern that’s likely to emerge in ERCOT for future co-located projects: full backup power is likely to become an absolute necessity under the SB 6 framework. For facilities like Amazon’s with extremely high availability SLAs, full backup power was probably always a baseline requirement. So this precedent seems unlikely to dissuade those projects. The precedent from Docket 58881 (Crusoe One) and Docket 58872 (Freestone) already points in this direction. Docket 59220 (Crusoe Two) will determine whether that precedent solidifies or whether the Commission narrows the scope in response to Ensign’s proportionality argument.

Withdrawals: 53.4 GW (384 projects)

• Roughly 80% of all withdrawn capacity in this period is from PJM clearing out legacy, serial queue requests. Setting those aside, other withdrawals this period total 9.5 GW, and are concentrated in MISO and CAISO.

• PJM: 42.9 GW (354 projects)

• MISO: 3.0 GW (4 projects)

• CAISO: 2.7 GW (10 projects)

• Arizona Public Service: 2.0 GW (1 project)

• Less than 1 GW of withdrawals in both ERCOT and the Southeast (Southern Company)

Additions: 44.5 GW (97 projects)

• Arizona Public Service: 28.2 GW (58 projects)

• ERCOT: 12.1 GW (26 projects)

• Southeast: 2.0 GW (3 projects), all Duke Energy (Carolinas and Progress).

• Outside the APS block, gas led the new requests (8.8 GW, 12 projects), ahead of storage (4.7 GW), a shift from the composition of new additions last period (solar+storage led the way last period).

In the News

• America’s largest wind farm is now spinning. Pattern Energy brought its 3.65 GW SunZia project in New Mexico online, making it the largest wind farm in the country. A single 3.65 GW resource reaching operation is one of the larger commercial-operation milestones we expect to track all year, and a sign that some long-stalled western megaprojects are finally reaching the grid.

• Big tech keeps building around the grid. Google and Intersect Power are developing the Meitner Energy Center in Texas, pairing a data center with more than a gigawatt of co-located wind, solar, storage, and on-site gas. It is their first project since Alphabet’s $4.75 billion acquisition of Intersect, and the co-located supply is meant to serve the data center’s load while limiting new demand on the local grid.

• PJM opens a fast lane for shovel-ready generation. FERC has approved PJM’s expedited interconnection track, which will fast-track up to 10 projects a year for resources of at least 250 MW that can reach operation within three years. The carve-out runs through the end of 2027 and targets PJM’s resource adequacy needs as data center demand outpaces supply, with the first projects possibly named in October.

• SPP gives large loads a conditional on-ramp. FERC approved SPP’s Conditional High-impact Large Load Service, letting large new loads such as data centers connect on a non-firm, interruptible basis until they secure firm resources or the needed network upgrades are finished. SPP says the structure gives developers more certainty on timing and cost. Alongside PJM’s fast lane, it shows RTOs improvising ways to absorb large loads in the near-term.

• A Texas test case is setting the rules for co-located data centers. Crusoe, an AI data center developer, and the Goodnight wind farm asked regulators back in October to approve a net-metering deal that puts the data center behind the wind farm’s existing grid connection. ERCOT found no reliability problems but recommended approval only with strict curtailment terms, including a 30-minute shutdown during grid emergencies. The developer is contesting, and as one of the first contested cases under Senate Bill 6’s co-location policy, whatever the commission adopts will establish the template in ERCOT moving forward. It remains in contested hearings as of mid-June, with no ruling yet.

Activity Map

PJM accounts for the bulk of this period’s withdrawals, but based on our review of the data, covered in more detail below, we believe this is largely PJM clearing out older, stranded serial requests rather than active queue projects truly withdrawing. Outside of PJM, Arizona Public Service is driving new requests, while ERCOT shows a mix of new entries, withdrawals, newly operational projects, and newly signed GIAs.

Queue Activity

The two main figures this period, 44.5 GW (97 projects) of new entries and 52.4 GW (384 projects) of withdrawals, are each the product of a single-entity data event rather than a shift in the market.

Of the 52.4 GW of withdrawals, about 42.9 GW across 354 projects is PJM. Looking at the data, our assessment is that these withdrawals are clerical rather than formal withdrawals during this period. These are requests from PJM’s final serial queue intake windows, filed between 2021 and 2023 and nearly all still at the first study phase. We read this batch of withdrawals as PJM formally closing out its legacy serial queue as it moves to the cluster process, not as active projects leaving. The one exception worth noting is the Pilesgrove Solar project in New Jersey (149 MW), which is the only project in the group that progressed beyond the feasibility study phase and actually withdrew after executing an interconnection agreement.

That also means the technology split of this period’s withdrawals is an artifact of the cleanup rather than a signal about any resource. For example, 9.5 GW of offshore wind that withdrew in PJM this period comes from six serial requests being removed from the queue. We will be monitoring and reporting on the data from PJM’s Cycle 1 of the reformed process and will also cross-check the set of withdrawn PJM projects from this period against the new data once it drops.

Non-PJM withdrawals total roughly 7 GW this period, and are concentrated in MISO and CAISO. MISO lost roughly 3 GW, led by NIPSCO’s 1.1 GW Malden gas plant and a 1.5 GW CLECO request that withdrew prior to initiating the study phase. CAISO’s 2.7 GW of withdrawals across ten projects are all from the same April 2021 cluster, and withdrew during the System Impact Study stage, likely after receiving their study results and being required to commit additional deposits. A 2.0 GW APS request also dropped, though it dates to 2017 and carries no withdrawal date, so we suspect this is also the product of the utility doing some queue housekeeping.

New entries this period are inflated by a single source. APS accounts for 28.2 GW of the 44.5 GW across 58 projects. These requests have been accepted into APS’s queue but sit in deficiency review, meaning the submissions still need corrections, so their resource types and study details are not yet published. We expect that information to fill-in over the coming weeks and will analyze the batch properly once it does. The conventional new-entry activity is in ERCOT, which added 12.1 GW across 26 projects, and the Southeast, where Duke Energy added 2 GW. Among the new requests with populated resource type data, gas led at roughly 8.8 GW, ahead of storage at 4.7 GW.

Queue Snapshot - Current State

The active queue stands at 1.79 TW across 8,330 projects. Part of the decrease this period is the PJM cleanup working its way out of the active totals, and not an indication of developers losing interest in the region.

The more durable story is in the mix. Firm and dispatchable resources continue to gain ground, though the queue is still overwhelmingly solar and battery by volume. One caveat on the “Other” category, which is up three-fold to about 75 GW. Much of that growth is simply unclassified new entries like the APS batch that have not yet been assigned a technology, so it overstates how much genuinely uncategorized capacity is entering the queues.

Notable Projects

The largest projects this period are gas. There are gigawatt-scale gas plants entering the ERCOT queue, and the largest newly operational plant is gas as well. The largest withdrawals, as discussed above, are PJM cleaning up its queue rather than real cancellations.

At GridTracker, we are also tracking the data center buildout (existing data centers, permitting, and construction). Using this data, we find that the largest gas plants entering the queue are landing near existing or planned/proposed data center facilities. The Giant Arc I (1.3 GW) gas plant in Pecos County, TX is registered to an entity called Powering Knowledge, LLC (an opaque entity, but likely a shell company owned by a large energy or data center developer), and is located in the middle of a growing West Texas compute corridor. Within roughly 30 miles sit CoreWeave’s 250 MW site and Poolside AI’s 2 GW Project Horizon (currently under construction), with much larger proposed campuses from Microsoft (about 2.6 GW) and Pacifico Energy (the 7.65 GW GW Ranch) nearby. The same pattern appears to the north, where the two >1 GW Thunder Bird gas units in Jack County sit on the western edge of the Dallas-Fort Worth data center build-out. Though we cannot see the offtakers behind any of these projects, it looks like the firm capacity entering ERCOT’s queue is clustering near data center facilities.

In the News

• Even NERC can’t make sense of data center load growth: NERC released its 2026 Summer Reliability Assessment last month. The report found that the grid added 58 GW of summer resource capacity, predicted a summer peak demand of 865 GW, and noted difficulty forecasting large-load and data-center interconnections, with their near-term load forecasts revised downward in several regions as those loads come online more slowly than expected.

• Rate payers in PJM may already be feeling pain from data centers. PJM’s market monitor reported wholesale power averaged $136.53/MWh in the first three months of 2026, up from $77.78 a year earlier. This roughly 76% jump is a symptom of rising demand from data centers and other customers in the region.

• Coal gets another boost. On June 4, DOE announced $850 million in funding to support the coal sector, including up to $425 million in Defense Production Act funds to modernize more than a dozen existing facilities alongside a separate $350 million tranche backing four projects, among them two new plants in Anchorage, Alaska (1.25 GW) and Mt. Storm, West Virginia (1.6 GW). These would be the first new U.S. coal plants to come online since 2013.

• The 5% safe harbor is back, for now. A federal court vacated IRS Notice 2025-42, restoring the safe harbor as a way for wind and solar to projects greater than 1.5 MW to establish beginning of construction under the 45Y and 48E credits, less than a month before the July 4 deadline. The court found that the Treasury never adequately explained the change and unfairly singled out wind and solar, though the ruling could still be appealed.

Where’s the Activity?

Three queue activities stand out, each covered in more detail below: SPP's DISIS-2024-001 cluster withdrawals in the central US, BPA's withdrawals in the Pacific Northwest, and PSCo's new requests in eastern Colorado.

Activity at a Glance

Withdrawals are the story this period: 38.2 GW exited the queues (up 737.5%) while new entries slowed to 20.3 GW (down 45.1%). Both dynamics are mostly a matter of major cluster updates being published. Beyond the headline flows, GIA signings ticked up (21 projects, 4.8 GW, +15.3%), while the newly operational and suspended tallies are too small to read much into.

Regional Breakdown

Net of new entries and withdrawals, most markets experienced only modest changes to their queues: the West added 7.2 GW from the PSCo entries, MISO and the Southeast posted smaller net gains (+3.5 GW and +1.2 GW, respectively), and CAISO and PJM saw minor net declines (−1.3 GW and −0.2 GW). SPP experienced a net −28.3 GW swing that accounts for essentially all of the period’s contraction.

GridTracker subscribers will have seen our March report on the Phase 1 study results for SPP’s DISIS-2024-001 cluster. As we saw in that report, DISIS-2024-001 is the largest interconnection cluster in SPP history, with more than 250 projects and 66.5 GW seeking interconnection. The Phase 1 study process allocated $30.2 billion in network upgrade costs, with a median project cost of $408/kW. In that report we flagged that many of these projects sat in the path of newly planned 765 kV transmission lines and had been assigned massive upgrade costs to help fund them, and that heavy attrition was likely. After Phase 1 results were posted, they had 15 business days to advance into the next study phase or withdraw. SPP has now updated its queue to reflect those decisions.

The post-Phase 1 decisions played out as we predicted. Attrition was substantial and clearly driven by costs. Nearly half the cluster’s projects (122, totaling 28.1 GW) withdrew. As we predicted in our March report, the withdrawn projects were largely those which faced the highest upgrade costs. Withdrawn projects had a median allocated cost of $655/kW versus $244/kW for those that stayed. 72% of the withdrawn cohort had allocated costs above the $408/kW median identified in our Phase 1 analysis, compared to just 26% of those that remained. Of the cluster’s $30.2 billion in allocated costs, roughly $19.3 billion, about two-thirds, was allocated to projects that have now exited.

Those costs are overwhelmingly shared network upgrade costs rather than POI costs. 91% of the withdrawn projects’ allocated costs were for network upgrades and only 9% for POI facilities. The largest of those network costs trace to a single 765 kV corridor: the Minco, Phantom, and Woodward EHV ties into Crawfish Draw are the biggest line items in the withdrawn cohort, each allocated between $600 and $700 million across roughly 30 of the withdrawn projects. The Southeast study region shed the most capacity (42 projects, 10 GW) but at a moderate $431/kW median, while the Southwest and Central study regions carried the highest median upgrade costs among the withdrawn ($980/kW and $923/kW, respectively) and the two largest total cost burdens ($6.9 billion and $6.1 billion).

The DISIS-2024-001 cluster was almost entirely composed of projects seeking full-deliverability: 241 of 251 active projects requested NRIS service, requiring study for full network deliverability. Within the set of NRIS projects, the projects that withdrew faced a $655/kW median against $262/kW for those that stayed. However we cut the data, the result is the same: upgrade costs are what separated the projects that withdrew from the ones that stayed in the queue.

Outside SPP, two regional stories played out. BPA posted 4.4 GW of withdrawals across 15 projects in Washington and Oregon, all of it renewables and storage. Storage and storage hybrids made up the bulk, led by a single 1 GW battery exit, with wind accounting for most of the rest. PSCo’s new requests cut the other way: 13.3 GW of additions across 46 projects, overwhelmingly solar and storage. Solar+battery hybrids led at 5.3 GW, with standalone solar and battery close behind (about 2.4 GW each) and wind adding another 1.8 GW.

Notable Projects/Trends

A few individual projects worth flagging. Counter to the broader pattern we've observed recently, where renewables and storage made up the bulk of withdrawn capacity, the single largest project to withdraw was a 1.3 GW gas plant in SPP (Oklahoma Gas and Electric). In terms of additions, the standout is the Double C Energy Center, a roughly 1.25 GW Entergy Arkansas development in Crittenden County, AR, that includes an 826 MW solar+battery facility and a 421 MW battery facility. The development is located near Google's $4 billion West Memphis data center, announced in October 2025 and powered by Entergy. It interconnects directly into the West Memphis 500 kV line. It's an early, concrete example of hyperscaler energy procurement showing up in the generator interconnection queue. That’s something we expect to see more of, and will continue to track, as data center buildouts accelerate. On the operational side, little came online. The largest was a 200 MW solar project in MISO (Michigan), alongside four smaller storage and solar+storage projects in CAISO from Southern California Edison.

A Quick Introduction

Welcome to the first issue of our newsletter, authored in partnership with . Nick spent two years at Lawrence Berkeley National Lab’s Energy Markets and Policy Group, where he contributed to Queued Up, the annual report widely treated as the standard reference on U.S. interconnection queues. We worked closely with Nick during his time at LBNL, and there’s nobody we’d rather have helping us unpack the queue data every two weeks. This newsletter delivers biweekly insights into the most relevant updates that affect the U.S. grid and the projects planning to interconnect to it. We’ll surface relevant news, regulatory insights, and of course, in-depth intel on what is changing in the interconnection queues across the country.

Executive Summary

The past 2 weeks have seen exceptional activity in the queues. 157 new projects totaling 36.92 GW entered the queues against 4.56 GW of withdrawals, largely driven by 25 GW of additions from Southern Company’s 2026 cluster window. The broader renewable versus firm/thermal bifurcation of the queues continues: gas led additions this period (roughly 20 GW added, +50% YoY), while renewable and battery storage queue capacity continues to contract. Regional trends and totals will be impacted by the 811 recently announced new projects (220 GW) from the first cycle of PJM’s reformed interconnection process.

In the News

• PJM capacity market overhaul. PJM released a whitepaper last week, Powering Reliability Through Market Design, proposing three frameworks for reforming its capacity market amid skyrocketing demand.

  • The options outlined are:

    • Stabilize the existing capacity market

    • Differentiate grid reliability by customer type or geography

    • Transition to an energy and ancillary services market with contracting requirements to guard consumers against energy price volatility.

  • FERC approved PJM’s extension of the existing capacity auction price cap and floor for two more years on April 28th.

• FERC action on large load interconnection is looming. Last month, FERC announced that they will act by June on DOE’s October 2025 ANOPR (Docket RM26-4-000). The ANOPR directs FERC to issue a set of reforms standardizing the interconnection process for data centers and other large loads.

• NextEra & Dominion mega-merger announced. NextEra Energy announced on May 18th it has agreed to acquire Dominion Energy in a $67 billion deal, creating the largest regulated utility business in the U.S. Particularly timely given Virginia’s April 2026 legislation requiring Dominion to procure 16 GW of short-duration storage and 4 GW of long-duration storage by 2045.

• Hot rocks and hot stocks. Geothermal continues to have its moment. Fervo Energy raised $1.89 billion in its IPO this past week. Amazon recently announced a PPA for 100 MW of geothermal from Zanskar in Nevada.

Where’s the Activity?

New queue entries during this period are clustered most heavily in the Southeast, ERCOT, and the Pacific Northwest (Avista). We also see a smattering of queue additions across the non-CAISO West (PacifiCorp/Idaho Power) and the Midwest/Plains.

The Southeast led all regions in new capacity additions at just under 26 GW, driven almost entirely by new gas projects in Southern Company’s service territory following the April 3rd close of Southern Company’s 2026 cluster request window. ERCOT added another 6.5 GW of capacity over the past two weeks, with three of the five largest new requests sited in Texas.

Withdrawals were modest and broadly scattered during this period. No single region or utility drove meaningful attrition, and at 4.56 GW, this period’s withdrawal volume was roughly 60% lower than the prior two-week period.

More than 700 GW of capacity exited U.S. queues in 2025 as FERC Order 2023 and other ISO- and utility-specific reforms cleared out a backlog of projects unlikely to ever be built. The relative lull in withdrawals over the last two weeks may not be indicative of a slowing of withdrawal rates in 2026. Two major ISO clusters could drive significant withdrawals this year. SPP has yet to publish updates to its DISIS 2024 cluster data since its Phase 1 results in March, and PJM’s first reformed cluster window (811 projects, 220 GW) only closed on April 27th, with no early-stage withdrawals yet reflected in the PJM data.

Newly operational projects appeared across the country, with battery projects coming online in CAISO and ERCOT, solar in SPP and the Southeast, as well as gas and oil in ERCOT and the Southwest. We also see roughly 4 GW (19 projects) with newly signed GIAs in the queue data over the past two-week period, a 142% increase compared to the prior two-week period. Most of these newly signed GIAs are clustered in the central U.S. (ERCOT and SPP) and mainly for solar and battery storage projects.

Activity at a Glance

The first two weeks of May have been a relatively active period for U.S. interconnection queues. 157 new projects totaling 36.92 GW entered the queues, a 250% jump from the prior two-week period. Only early April (50 GW added) saw more new queue capacity over the past six months.

After years of surging requests from renewables (mainly solar and storage) we are now seeing gas rebound and continue to drive additions to the queue, accounting for more than half of all new capacity this period (~20 GW). Batteries (~10 GW) were the second largest contributor to the increase in queue capacity over the last two weeks.

Withdrawals were comparatively muted at 4.56 GW across 26 projects. The tech mix of withdrawals largely tracks the composition of the active queue. Battery storage and solar represent the largest shares of both currently active queue and recently withdrawn capacity. Six projects (864 MW total) suspended their queue request during this period.

Other parts of the queue ecosystem were active as well. 28 projects totaling 3.78 GW were reported as newly operational (up over 800% vs. the prior two-week period), and 21 projects (4.17 GW) appeared with newly signed GIAs (up 142%). Two-week snapshots of these metrics depend on utility and ISO data publication cadence, but the simultaneous uptick is a positive signal for project progression in 2026.

Queue Snapshot

Overall U.S. queue capacity is continuing its multi-year contraction into early 2026. Active queue capacity now stands at 1.83 TW across 8,769 projects, down more than 200 GW from the end of 2025 (2.061 TW) and marking the second consecutive year of contraction following the 20–40% annual growth that defined 2019 to 2023. Two opposing YoY trends define the current state of the queues: the continued contraction of renewables and storage, and the rapid expansion of firm resources (mainly gas).

Every major renewable and storage category is down YoY. Solar fell 24% (now 446 GW), solar plus battery hybrids dropped 21% (305 GW), wind shed 22% (198 GW), and offshore wind contracted by 13% (16 GW). Storage, which had seen substantial growth through 2023, has also entered the contraction phase with active battery capacity down 14% YoY (437 GW).

On the firm side of the queue, the trend is flipped. Gas is up 50% YoY at 273 GW, consistent with the surge that dominated 2025 additions and continues to lead recent activity. Nuclear capacity in the queue is up 75% to 14 GW, likely reflecting expectations around data center load. Geothermal is up 114% (nearly 4 GW), and even diesel (+282%) and coal (+5%) are growing.

Regionally, the queue remains heavily concentrated in three markets: the non-CAISO West (~430 GW), ERCOT (~420 GW), and MISO (~350 GW). Together these three represent the bulk of total queued capacity. The Southeast (~160 GW), SPP (~170 GW), CAISO (~120 GW), and PJM (~120 GW) trail behind, though PJM’s recent cluster window (220 GW of new requests) will reshape regional totals once those projects are reflected in the queue data.

Regional Breakdown

The Southeast region added more new capacity over the last two weeks than every other market combined. 25.88 GW of new entries against just 470 MW of withdrawals yields +25.41 GW net for the region, driven almost entirely by gas projects in Southern Company service territory. ERCOT added another +6.02 GW net (6.50 GW in, 487 MW out), continuing the steady growth trajectory that has defined its queue since 2023. The West contributed +2.77 GW net. In the absence of new cluster window data (still no project-level details on PJM’s Cycle 1), all other markets saw net withdrawals, led by MISO at -1.23 GW. The remaining markets each saw less than 200 MW of net withdrawals.

The West has contracted from ~480 GW since last June, while ERCOT has held roughly steady. MISO, one of the busiest markets in 2025, has shed roughly 75 GW over the same window, working through the aftermath of its DPP 2022 and DPP 2023 cluster cycles. CAISO, PJM, Southeast, and SPP all hover in the 120–175 GW range while NYISO is down from ~45 GW to ~25 GW over the past year.

PJM’s recent reformed-process cluster window will reshape these rankings significantly. Once those 220 GW (811 projects) are reflected in queue data, PJM will jump from ~120 GW to roughly ~340 GW, putting it in line with MISO. We should start to see the new PJM requests reflected in the data in the coming weeks.

Notable Projects/Trends

The largest new requests in this period reinforce the broader trend we have seen in queues over the last year or so. Gas is continuing to dominate additions, and over the last two weeks the largest prospective gas projects are coming from the Southeast and ERCOT.

Four of the five largest new requests are natural gas. Two are from Southern Company (1.50 GW and 785 MW) and ERCOT also added two projects greater than 1 GW. The volume of large gas projects in these regions is another sign of the firm capacity build out that has been gathering momentum throughout 2025 and 2026, likely driven by rising data center load growth and lower interconnection costs.

Top takeaways from the LBNL report

This report confirms and extends the trends that we flagged in our 2025 retrospective analysis published in February 2026: queues contracted across the country by a meaningful margin overall in 2025. However, the distribution of these withdrawals reflects a stark difference between technologies. Renewables shrank across the board, while gas capacity grew dramatically in the major markets.

Q3 and Q4 of 2025 saw the most dramatic withdrawal volumes, likely due (at least in part) to the tax implications of the OBBBA, but also due to very large clusters in MISO and SPP entering critical decision point windows.

The Phase 1 results reveal a total of $30.2 billion in allocated network upgrade costs across the cluster, with a median cost assignment of $375/kW. Developers in this cluster now have 15 business days to determine whether to proceed in the queue or withdraw their request. Based on historical SPP withdrawal patterns, substantial attrition is likely.

DISIS 2024 Cycle Overview

The cluster’s unprecedented size is partly by design. The application window was extended by roughly five months following SPP’s FERC waiver request. The extension, combined with strong developer interest, produced a cluster more than twice the size of any prior cycle, and the pre-Phase 1 withdrawal rate had already exceeded 30% before a single cost assignment was posted.

Gas comprises the largest share of total active capacity at 17.7 GW across 33 projects. Solar (62 projects, 13.9 GW) and battery storage (74 projects, 13.9 GW) are nearly identical in total capacity. Solar + battery hybrids comprise 43 projects and 10.3 GW. Wind, historically a major resource type in SPP, accounts for just 32 projects and 9 GW, its smallest share of any recent DISIS cluster.

Load forecasts exploded thanks to an era-defining AI infrastructure boom.

Renewables were suddenly forced to grapple with the upending of incentives which were often foundational for their financial viability.

Supply chain woes compounded.

And sweeping queue reform was enacted swiftly in many regions.

The net impact of all of this: an unprecedented volume of withdrawals from interconnection queues, especially among renewable projects. But not all technologies were as battered as solar and wind. Gas projects swarmed the queues, with total gas capacity growing nearly 40%, while all other major technologies experienced a relentless culling.

The queue data tells you a project exists. But it doesn’t tell you who’s actually making decisions on it, what permits have been filed, or what FERC, state, or county proceedings might affect its timeline. That context lives across hundreds of scattered sources, and tracking it manually doesn’t scale.

So we built something to solve that.

Introducing GridTracker

GridTracker gives you real-time visibility into every generation project in every transmission interconnection queue across the continental US and Canada. But more importantly, it connects each project to the broader context that determines whether it will actually get built.

See the documents that matter

Immediately pull up relevant permits, press releases, FERC filings, and state PUC/PSC dockets in one click. No more hunting across multiple databases, and no more wrestling clunky government websites with incomplete and cumbersome search portals.

Find the actual decision-makers

This isn't a "who works at Company X" list from LinkedIn. We track who's attending relevant meetings and signing the paperwork. These are the people who are actually moving the projects forward.

Build precise watchlists and get notified

Define exactly the segments you care about. For example: "solar projects in ERCOT and SPP with planned CODs between May and October 2027, connecting at 69kV." (Side note: There are currently 13 projects matching those criteria, totaling 1.2 GW. The largest is Double A Solar in Goliad County, TX, owned by Birch Creek). You can track segments like this and get notified whenever something changes or a new project matches.

GridTracker is built on interconnection.fyi's real-time dataset, the same data trusted by organizations like Lawrence Berkeley National Lab for their Queued Up report. We've layered on a deeply curated collection of additional sources to give you the full picture.

Regional Capacity Changes (2023 → 2024)

The interconnection.fyi team went digging through our historical dataset to see how active queue volumes have shifted year-over-year — and for the first time in recent memory, they're shrinking.

The chart below compares 2023 vs. 2024 cumulative active capacity by fuel type and planning region, comparing snapshots taken at the end of each year. It reflects only projects that remained active at the end of each year, excluding anything withdrawn, completed, or otherwise removed from the queue. Green bars indicate an increase from 2023 to 2024; red bars represent a decrease.

That sea of red? It's not what we're used to seeing.

For years, active queue volumes grew at a breakneck pace — fueled by a surge of solar, wind, and storage projects. But in 2024, that trend reversed. Offshore wind fell by over 50%, solar dropped nearly 12%, and hybrid storage declined by nearly 20%.

So what changed?

Most signs point to queue reform. Over the past 18 months, ISOs like PJM, MISO, and CAISO implemented new rules requiring higher deposits, stricter site control, and milestone-based study processes. On top of that, FERC Order 2023 — while not yet fully implemented — means that these changes are here to stay. The one major exception? ERCOT, which isn't subject to FERC rules and continues to operate under its own policies.

One notable exception to the contraction trend was MISO, which saw a significant increase in queued capacity across nearly every fuel type. At first glance, this might seem to contradict the broader story — but it likely reflects a timing artifact, not a structural break.

MISO's queue was largely frozen in 2023 as it transitioned to a new interconnection process. When it reopened in early 2024, a wave of new applications entered — potentially representing deferred demand from developers waiting on clarity around the new rules. In this light, MISO's growth doesn't undermine the queue reform hypothesis — it just reflects how differently that transition played out across regions.

It's too early to tell if this is a lasting correction or a temporary reset — but 2024 marks a clear turning point in the evolution of interconnection queues.

While some of the recent decline in active queue capacity might be attributed to fewer new applications, that's not the whole story. In fact, 2024 saw a massive spike in project withdrawals. Among projects with reported withdrawal dates (which is only about half of all withdrawn projects), plus withdrawals from CAISO cluster 15[1], 296 GW of capacity was withdrawn from the queues last year — more than double the amount withdrawn in 2023, and by far the largest annual total in the dataset.

The number of individual projects withdrawn also surged, jumping 96% year-over-year. This points to a broader structural shift: queue reform processes are not just filtering future applicants — they're forcing existing projects out. The bottleneck isn't closing at the entrance; it's clearing out the middle.

Queue Timelines (2023 → 2024)

How long does it take to get through the queue?

To answer that, we analyzed the time between a project's interconnection request and its eventual commercial operation date (COD). For each power market, we calculated the median and interquartile range (25th to 75th percentile) of queue-to-COD durations for projects that reached COD in a given year.

These charts reveal that typical development timelines remain stubbornly long — often 3 to 5 years — with wide variability depending on the market. Some regions like PJM and the Southeast show relatively consistent durations, while others like SPP display more volatility and longer median timelines. Nationally, there's no clear evidence yet that queue reform efforts have meaningfully shortened the path to COD.

Note: ERCOT and NYISO are excluded from this analysis due to insufficient historical data for meaningful timeline comparisons. Including ERCOT would likely decrease the median timeline.

Note: These figures likely undercount the total number of projects reaching COD each year, as we can only include projects that report their actual commercial operation dates in interconnection queue data.

Withdrawal Timelines (2023 → 2024)

What about the projects that didn't make it?

To better understand the other side of queue attrition, we looked at how long withdrawn projects had been sitting in the queue before exiting. For each power market, we measured the time between a project's interconnection request and its withdrawal, and calculated the median and interquartile range for projects withdrawn in a given year.

The picture that emerges is just as striking. In 2024, many withdrawn projects had been in the queue for 4 to 5 years — a meaningful amount of time for developers to invest before walking away. In markets like CAISO, the median project sat in the queue for over 5.4 years before withdrawing. PJM, Southeast, and MISO show slightly shorter timelines, but still hover around the 3–4 year mark.

Importantly, this analysis includes only the roughly 50% of withdrawn projects that report a withdrawal date. While incomplete, we believe the trend is representative; these aren't just speculative applications disappearing overnight. In many cases, they're projects that stuck it out for several years before ultimately exiting, likely due to delays, reform-driven barriers, or shifting market conditions.
