Carrington","Maya Jiménez"] published: 2026-06-22 updated: 2026-06-18 articles: 23 --- # 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. [Read on the website]() ## Issue 37 — Cascading Effects How climate reshapes business, insurance, and infrastructure affecting everyday lives ### Compound Failure - [Adequate Under Conditions That No Longer Exist]() — By [Seth D. Carrington]() · Published 2026-06-17 · Format: Compound Failure NERC's summer reliability assessment flags drought, extreme heat, demand growth, and hydropower decline across the Western grid. It evaluates each as an independent scenario, separated by "or." Summer 2026 is delivering them with "and," simultaneously, across 62 percent of the continental U.S. Lake Mead is approaching the elevation where Hoover Dam loses most of its turbines. And inside the Western grid's own reliability organization, a manager is building ad hoc models with national laboratory partners to ask the compound question the standard framework was never designed to pose. ### The Bottleneck - [Everybody Got in Line at Once]() — By [Seth D. Carrington]() · Published 2026-06-17 A large power transformer is wound by hand, built to specification, in factories running at 98% of global capacity. When one is destroyed, the replacement enters a queue averaging [128 to 144 weeks](https://electricaltrader.com/blogs/news/transformer-shortages-supply-chain-impact-pricing). The U.S. imports roughly 80%. One company makes the specialized core steel domestically. ### Grid Stress Signals Six federal and regulatory assessments published this spring, taken together, map the supply-side pressure bearing down on the U.S. electricity grid as summer 2026 begins. Demand is climbing at its fastest rate in four years. The hydropower systems that backstop regional grids are producing at historic lows. The physical infrastructure carrying all of it just received a near-failing grade from the engineers who evaluate it. No single finding here constitutes a crisis. But the margin between adequacy and shortage has narrowed to the point where a sustained heat event could close it. The numbers are all public. The convergence is worth seeing in one place. - **Peak Demand Climbs Eleven Gigawatts Over Last Summer** — [Source]() — Published 2026-06-17 Tag: Peak Demand NERC's 2026 Summer Reliability Assessment puts aggregated peak demand across all assessment areas at more than 11 GW above its 2025 figure. Last year's 10 GW jump preceded multiple summer stress events. This one is larger. - **Summer Electricity Consumption Growing Fastest Since 2022** — [Source]() — Published 2026-06-17 Tag: Summer Load FERC projects total summer 2026 electricity consumption at 1,587 TWh, a 3% year-over-year increase, citing EIA data. Electrification, data center buildout, and rising cooling loads are driving the strongest summer growth rate in four years. - **Cooling Degree Days Point to a Brutal Quarter** — [Source]() — Published 2026-06-17 Tag: Cooling Demand EIA's May 2026 Short-Term Energy Outlook projects roughly 1,610 cooling degree days nationally, 4% above 2025. Third-quarter projections run 8% above the prior year and 5% above the ten-year average. Peak stress concentrates in July through September. - **Lake Powell Inflow Hits Lowest Level on Record** — [Source]() — Published 2026-06-17 Tag: Water Supply The Bureau of Reclamation's May 2026 forecast projects Lake Powell's April–July unregulated inflow at 0.800 million acre-feet, 13% of the historical average. That is the lowest spring runoff since Glen Canyon Dam began operating in 1964. Regional hydropower output falls with it. - **Canadian Hydropower Exports Fall to Two-Decade Low** — [Source]() — Published 2026-06-17 Tag: Import Decline Canadian electricity exports to the U.S. dropped 28% in 2024 to 35.64 TWh, per the Canada Energy Regulator. That was the lowest figure since 2004. Statistics Canada reports exports fell further in 2025, setting a new series low. Drought and rising Canadian domestic demand are both factors. - **Civil Engineers Downgrade U.S. Energy to Near-Failing** — [Source]() — Published 2026-06-17 Tag: Infrastructure Grade ASCE's 2025 Infrastructure Report Card dropped U.S. energy from C- to D+, citing transformer shortages, surging demand from electrification and data centers, and stalled transmission modernization. Since 2000, weather has caused 80% of major electricity outages, most concentrated in the last decade. ### Further Reading - **From Tail Risk to Design Baseline: How the Grid Is Adapting to Extreme Heat** — [Source]() — Published 2026-06-17 NERC's summer 2026 outlook quantifies what grid operators already feel: extreme heat is the new baseline, not the exception. - **The Emerging Danger of Post-Hurricane Heat Waves** — [Source]() — Published 2026-06-17 After Beryl, Houston families sat powerless in lethal heat. The compound event no grid planning model anticipated. - **Power After the Storm: What a Decade of Central U.S. Outages Reveals About Compound Climate Risk** — [Source]() — Published 2026-06-17 Every one of the 100 worst MISO outage days was weather-driven. Sequential storms leave no recovery window. - **A Warning for the AI Era: Why America's Energy Infrastructure Isn't Ready** — [Source]() — Published 2026-06-17 Data centers are claiming grid capacity that aging infrastructure can't spare. A structural mismatch with no easy resolution. - **The Hardware Bottleneck: Transformer Shortages Are Stalling Grid Resilience** — [Source]() — Published 2026-06-17 Four-year lead times for transformers mean rural co-ops and data centers compete in the same queue. ### Who Gets Hurt Grid reliability gets measured in reserve margins. Megawatts on paper. What doesn't appear in those assessments: the 35 million Americans without air conditioning, the 4.5 million Medicare recipients whose medical devices need a working outlet, or the fact that Black households are fifty percent more likely than white households to lack cooling. On the week the country marks Juneteenth, that disparity deserves more than a footnote. This summer, drought covers 62% of the lower 48. Major blackouts have surged more than 60% in recent years. Hydropower reservoirs are running dry. The weather offices that warn communities before compound disasters hit have been hollowed out by staffing cuts. The cards below map what system-stress dashboards were never built to show: who is actually exposed when heat and power failure arrive together. - **Major Blackouts Have Surged Sixty Percent in Five Years** — [Source]() — Published 2026-06-17 Tag: Blackout Trend Major U.S. blackout events — those hitting 50,000-plus customers for an hour or more — jumped over 60% in a recent five-year period, according to a peer-reviewed Georgia Tech analysis. Every one of the ten worst central U.S. outages in the past decade was triggered by extreme weather. - **When Heat and Blackouts Overlap, Whole Cities Suffer** — [Source]() — Published 2026-06-17 Tag: Compound Risk Researchers modeled simultaneous heat waves and power failures in Atlanta, Detroit, and Phoenix. Between 68% and 100% of residents faced elevated heat-stroke risk. In Phoenix, more than half the population could require medical attention. The culprit is near-total dependence on air conditioning that no longer has power behind it. - **Thirty-Five Million Americans Still Lack Air Conditioning** — [Source]() — Published 2026-06-17 Tag: Cooling Gap More than 35 million people have no AC at all. The gap falls along familiar lines: 15% of Black households and 14% of Hispanic households lack cooling, compared to 10% of white households. Nearly one in five low-income households reported keeping their homes at unsafe temperatures for months at a stretch. - **Millions Need Electricity to Stay Alive at Home** — [Source]() — Published 2026-06-17 Tag: Medical Vulnerability At least 4.5 million Medicare recipients rely on electricity-dependent medical devices. After Hurricane Beryl knocked out power to 3 million Houston-area customers, Pamela Jarrett, 64, who depended on a feeding tube, died on day four. Priority reconnection lists existed. They did not reach her in time. - **Drought Is Draining the Grid Before Summer Peaks** — [Source]() — Published 2026-06-17 Tag: Drought Pressure Sixty-two percent of the continental U.S. is in drought. Lake Powell expects 13% of average inflow, putting up to 4,500 MW of Colorado River hydropower at risk by August. Canadian hydropower exports dropped 28% last year. Water generates electricity. Less water means less cooling, arriving at the worst possible moment. - **Forecast Office Cuts Leave Grid Operators Guessing** — [Source]() — Published 2026-06-17 Tag: Data Gaps The National Weather Service has shed nearly 600 staff. Forty percent of forecast offices now carry significant vacancies. Grid operators rely on these offices to see compound events coming. Before the July 2025 Texas flash flood that killed more than 100 people, the responsible forecast office had already lost 22% of its meteorologists. ### Favorite Featured Stories - [The Trap — When Insurance Disappears and the Mortgage Doesn't]() — By [Maya Jiménez]() · Published 2026-06-10 · Format: The Mortgage Trap Darlinda Cook's monthly mortgage payment jumped from $800 to $1,400. The entire increase was insurance. When her carrier left Louisiana, her servicer force-placed a policy that costs multiples of what she'd been paying, covers only the lender's collateral, and cannot be negotiated. Two companies dominate this market. No Louisiana regulator has investigated it. A Dallas Fed study ties a $500 premium spike to a 20 percent rise in mortgage delinquency. The Levy Institute sees mechanics structurally analogous to 2007-08. The chain is already running in Louisiana's coastal parishes, and it has an order of operations. - [Adequate for a Summer That No Longer Exists]() — By [Seth D. 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 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. ## Other sections in Issue 37 - [Human Stories]() - [Emerging Science]() - [Future Tense]() - [Climate Past]() - [The Lab]() ## More - [Publication guide]() - [Issue archive]()
