Carrington","Maya Jiménez"] published: 2026-06-07 updated: 2026-06-03 articles: 21 --- # The Docket > The Docket is a weekly publication about the decisions climate change is already putting in front of Americans: whether to buy the generator, whether the flood insurance is enough, whether to stay in the city you love. It follows the people making those choices now. It treats climate anxiety as a reasonable response to real conditions. It won't tell you what to do, but it shows the tradeoffs clearly.

Carrington]() · Published 2026-06-02 · Format: The Planning Gap On May 18, the grid operator serving 65 million people across thirteen states needed a federal emergency order to avoid rolling blackouts. Temperatures hit the nineties in mid-May while 40,400 megawatts of generation sat offline for scheduled maintenance. Scheduled correctly, according to a calendar that no longer describes the weather. The next day, the national reliability authority declared the same grid adequate for summer. Both findings were accurate. They measured different things, against different assumptions about what "normal" looks like. The distance between those two numbers is where people get hurt. ### The Blocked Fix - [Where Is the New Generation? Behind a Five-Year Queue and a Transformer That Hasn't Been Built]() — Published 2026-06-02 Roughly 2,600 gigawatts of generation capacity sit in the interconnection queue. That is more than double what the entire US grid produces today. The median project waits nearly five years to connect. Close to 80 percent withdraw before they get there. ### Summer Risk Map Grid reliability assessments answer a specific question: can the system handle a normal summer? Climate change is making normal summers rarer. That gap between what gets planned for and what actually shows up is where this summer's risk concentrates. Five signals worth watching as heat season opens. Several look reassuring at the headline level. Underneath, the picture is harder to read: margins tightening, seasons shifting faster than maintenance schedules can follow, federal emergency powers quietly becoming a regular operational tool. What connects them is a planning architecture still calibrated to historical weather. The weather has moved on. - **DOE Ordered Data Centers Off to Prevent Blackouts** — [Source]() — Published 2026-06-02 Tag: Emergency Order On May 18, DOE authorized PJM to curtail data centers and large loads with backup generation across 13 states. The trigger: over 40 GW offline for routine spring maintenance while projected demand hit 135,961 MW. The order lasted three days. Nobody called it routine. It was. - **Fewer Flagged Regions, but Read the Fine Print** — [Source]() — Published 2026-06-02 Tag: Risk Assessment NERC's summer assessment flagged three elevated-risk regions (New England, Saskatchewan, Pacific Northwest), down from six last year. Better headline. But NERC's John Moura added the caveat that matters: "Improved conditions shouldn't be interpreted as saying overall reliability risk is declining." - **Spring Heat Now Collides With Spring Maintenance** — [Source]() — Published 2026-06-02 Tag: Seasonal Shift NERC identifies the collision of early-season heat with scheduled maintenance outages as a growing reliability threat. May 18 proved the point: nineties arrived while 40-plus GW sat in pieces for planned work. The old assumption that June is prep time and July brings risk has quietly expired. - **New York's Summer Buffer Has Nearly Vanished** — [Source]() — Published 2026-06-02 Tag: Grid Margin NYISO reported a 417 MW reliability margin for summer 2026, down nearly 80% since 2022. Under a three-day 95°F heat wave, that margin flips to a projected 1,679 MW deficit. Generator retirements in NYC and Long Island are outrunning new capacity additions. - **El Niño Odds Keep Climbing Through Late Spring** — [Source]() — Published 2026-06-02 Tag: Climate Pattern NOAA's El Niño probability jumped from 61% in March to 82% for the May–July window, with a two-in-three chance it reaches "strong or very strong." Widespread extreme heat under those conditions would test grid margins already at their thinnest. Forecasts are still moving. ### Further Reading - **PJM Gets Emergency Approval to Curtail Data Centers, Large Loads During Hot Weather** — [Source]() — Published 2026-06-02 The primary trade account of the May emergency order, with exact reserve margin figures, the curtailment hierarchy PJM proposed, and the legal authority DOE invoked. Essential reading for understanding what "emergency" means in operational terms — and who gets curtailed first. - **The Power Grid Passed Its Report Card. But Read the Fine Print.** — [Source]() — Published 2026-06-02 NERC's 2026 Summer Reliability Assessment added 58 GW of new capacity and declared the grid adequate. This analysis walks through the three structural caveats buried beneath that headline, including what "normal conditions" actually assumes and where the definition breaks down. - **DOE's Emergency Order Signals New Role for Data Centers' Backup Power** — [Source]() — Published 2026-06-02 Gibson Dunn's legal analysis of the precedent DOE is quietly building: three emergency conscriptions of private backup generators since January 2026. If you want to understand what it means when a federal agency starts treating corporate diesel generators as a grid resource, this is where to start. - **U.S. Transformer Market Faces Severe Supply Constraints as Lead Times Extend to Four Years** — [Source]() — Published 2026-06-02 The physical bottleneck that makes the interconnection queue more than a bureaucratic problem. Four-year lead times for large power transformers, a 274% demand surge, and developers competing for factory slots mean that generation capacity approved today may not reach the grid until 2030. The hardware story underneath the planning story. - **US Power Grid Faces Strain as Heat Wave Drives Up Demand and Repairs Lag** — [Source]() — Published 2026-06-02 Bloomberg's broader infrastructure framing of the May emergency, with reporting on the maintenance backlog that compounds the capacity problem. Paywalled, but worth it for the detail on how shrinking shoulder seasons leave less time for repairs that used to happen in spring and fall. ### The Demand Accelerant Grid planners spent a decade assuming flat demand. Then data centers arrived at a scale nobody's models anticipated, and the assumption broke. A single industry now accounts for half of all new U.S. electricity demand growth. Wholesale prices have spiked hundreds of percent where facilities cluster. PJM, the grid operator serving 65 million people, says load growth is outrunning new generation. The federal government has twice invoked emergency powers to conscript private backup generators into public service. And the replacement power plants that might absorb the load? Stuck in a five-year interconnection queue, with four out of five projects dropping out before they ever deliver a watt. Five numbers that trace what happens when explosive demand collides with infrastructure built for a world of stable consumption. - **One Industry Now Drives Half of New Demand** — [Source]() — Published 2026-06-02 Tag: Demand Growth Data centers accounted for roughly 50% of all new U.S. electricity demand growth in 2025, per the IEA, and that share is projected to hold through 2030. American consumption is rising at more than twice the rate of the prior decade. No other country comes close. - **Electricity Costs Up 267% Near Data Center Clusters** — [Source]() — Published 2026-06-02 Tag: Price Shock Bloomberg analyzed wholesale prices at 25,000 grid nodes and found costs rose as much as 267% over five years near major data center activity. That's the peak, not the average, concentrated in corridors like Northern Virginia. But local price shocks don't stay local for long. - **PJM Says Data Center Load Outpaces New Generation** — [Source]() — Published 2026-06-02 Tag: Grid Warning PJM Senior VP Michael Bryson: the summer outlook "reflects a new reality — continued load growth driven by data centers that is outpacing the addition of new generation." Reserve margins are tightening. PJM can no longer reliably send surplus power to neighboring grids during emergencies. - **DOE Can Now Commandeer Data Center Backup Generators** — [Source]() — Published 2026-06-02 Tag: Emergency Powers A May 18 DOE emergency order authorized PJM to direct data centers' private backup generators into grid service as a last resort before rolling blackouts. A similar order came in January 2026. Gibson Dunn legal analysts call the pattern a "meaningful trend." Private backup power is becoming a de facto public grid resource. - **Replacement Power Stuck Behind a Five-Year Queue** — [Source]() — Published 2026-06-02 Tag: Generation Backlog The U.S. interconnection queue peaked near 2,600 GW, per Lawrence Berkeley National Laboratory. That's double the nation's entire installed capacity, on paper. In practice, 80% of projects withdraw before completion. Median wait times have stretched to five years, up from under two in 2008. The generation that would absorb new demand mostly doesn't exist yet. ### Favorite Featured Stories - [The Chain That Knows and Cannot Say]() — By [Maya Jiménez]() · Published 2026-05-27 · Format: The Architecture of Silence FEMA can now price flood risk to the individual structure. Congress caps the price signal. Appraisal standards require no climate analysis. A third of states impose no flood disclosure on sellers. Zillow built a climate risk score that changed buyer behavior, then removed it under industry pressure. At every node in the home-buying chain, someone holds information relevant to the biggest financial decision of a family's life. At every node, for its own structural reasons, that information does not pass to the next. The result is an architecture of omission. The risk stays. It shifts from a pre-purchase decision into a post-purchase liability that lands on the family least equipped to absorb it. - [The Shoreline That Was Promised]() — By [Maya Jiménez]() · Published 2026-05-20 · Format: The Frozen Project Alameda, California spent years engineering a $55.5 million shoreline adaptation plan and assembling a 30-partner coalition to apply for FEMA's BRIC program. The funding was canceled by memo, restored by court order, and reopened with a $20 million cap that structurally excludes the project it was meant to fund. Applications are due July 23. Bay Farm Island flooded in January, exactly where the city's maps predicted. The resilience officer who designed the integrated plan is now breaking it into fragments small enough to fit through whatever funding windows remain open. Construction, if it happens, won't start until 2030. The next storm season begins this fall. - [Paper Water]() — By [Maya Jiménez]() · Published 2026-05-12 · Format: The Last Overtime Full-service farmers on Colorado's Dolores Project will receive 3 inches of water this year out of a possible 22. Their rights say more. The river doesn't have it. In May, Arizona, California, and Nevada submitted a bridge deal cutting 3.2 million acre-feet through 2028. Colorado wasn't at the table. Now, in a Cortez boardroom, district managers are splitting 770 acre-feet in tied votes while the legal architecture governing western water approaches a renegotiation that will determine whether their communities survive. The allocation is a moving target. The deficit is not. - [Louisville Rebuilt Harder. Colorado's New Insurance Law May Not Know It.]() — By [Maya Jiménez]() · Published 2026-05-06 · Format: Showing the Math The houses on Via Appia Drive in Louisville, Colorado, have Class A metal roofs, fiber cement siding, ember-resistant vents screened to one-eighth of an inch. They replaced homes that a 100-mph grassfire took on December 30, 2021. The families who rebuilt them were 74 percent underinsured and did it anyway. On July 1, Colorado becomes the first state to require insurers to show homeowners the wildfire risk score driving their premiums. Louisville's rebuilders will finally see the number. The number may not see what they built. ## Other sections in Issue 35 - [Human Stories]() - [Emerging Science]() - [Future Tense]() - [Climate Past]() - [The Lab]() ## More - [Publication guide]() - [Issue archive]()
