The Lyceum: Power & Infrastructure Weekly — Jun 13, 2026

This was the week the AI buildout stopped being a power story and became an ownership story. The largest utility merger in American history is grinding through state commissions, FERC's most consequential rulemaking in a generation expires in roughly two weeks, and Google — for the first time — agreed to let the grid tell its data centers to power down. The through-line: a new data center is never just a data center. It's a power demand shock, a cooling decision, a water allocation fight, and increasingly, a question of who controls the wires.

• Eaton Virginia grid-to-chip facility (Eaton): A $50M+ investment in a new Virginia plant focused on integrated electrical infrastructure for AI data centers — from grid interconnection down to the chip.
• PJM Expedited Interconnection Track (PJM Interconnection): FERC-accepted on June 9, 2026 — a process to move up to 20 "shovel-ready" generation projects through faster studies over two years to address near-term resource adequacy.
• Google grid demand-response agreement (Google): A commitment to curb AI data center power use during grid stress events, per Reuters — the first hyperscaler agreement to operate as a flexible grid resource.

NextEra Energy will acquire Dominion Energy in a $66.8 billion all-stock transaction — the largest power-sector deal on record, creating the largest electric utility in the country. The deal was announced May 18 and is now entering state regulatory review.

The strategic logic is blunt. The acquisition gives Florida-based NextEra a foothold in Northern Virginia's "Data Center Alley," the world's largest concentration of data centers, where Dominion expects peak demand to double by the late 2030s on data center load alone. The combined company would serve roughly 10 million customer accounts across Florida, Virginia, North Carolina, and South Carolina and operate about 110 GW of generation.

What changes if this closes: control over the grid in the states that matter most for AI infrastructure consolidates under one operator — including, via NextEra's Seabrook station, effectively all the nuclear power produced in New England.
What failure looks like: regulators in Virginia, North Carolina, and South Carolina — plus FERC and the Nuclear Regulatory Commission — attach conditions that reshape the deal's economics or stall it outright. The observable signal is the formal FERC filing under Section 203, which starts the review clock and reveals how the companies plan to address market-power concerns in PJM. The transaction is expected to close in mid-to-late 2027.

The model grid operators have begged hyperscalers to adopt for years just got its first marquee adopter. Reuters reported that Google has agreed to curb power use at its AI data centers to ease strain on the U.S. grid when demand surges — a form of demand response, where Google voluntarily dials back consumption during peak stress in exchange for grid benefits. Reuters did not disclose which grid operator the agreement covers or the compensation structure.

The scale is what makes this matter. A single hyperscaler campus can draw 500 MW or more — a mid-sized power plant running in reverse. When ERCOT flagged data center trip events earlier this year, the worry was sudden loss of load destabilizing the grid. Demand response addresses the opposite problem: too much load during heat waves.

If this becomes a template, it rewrites data center siting economics — facilities that can flex their load become more valuable to utilities and may earn preferential interconnection treatment. What tells you whether it's real or PR: watch whether MISO — publicly flagging tight summer reserve margins — moves to formalize similar arrangements with large loads before peak, and whether Google discloses the MW commitment and operator.

Big Tech is moving past letters of intent toward nuclear structures with actual capital at risk. Reuters reported this week on the deal landscape: Meta's agreement with Oklo for a 1.2 GW nuclear campus in Ohio and Google's partnership with Kairos Power on a fluoride salt-cooled small modular reactor.

The structural problem these deals try to solve is baseload: a 200 MW AI training cluster can't pause because it's cloudy, and nuclear runs 24/7. The SMR pitch is that factory-built modular reactors compress the decade-plus, multi-billion-dollar timelines of conventional plants.

The Carnegie Endowment for International Peace cautioned that it's "still unclear" whether hyperscalers will make truly large bets — and the caution is warranted. Most announced deals are offtake agreements — promises to buy power if a reactor gets built — not equity that funds construction. The gap between a signed offtake and a commissioned reactor is measured in years and NRC approvals. The signal that separates hype from reality: any SMR developer reaching a formal Final Investment Decision with committed debt financing. Until then, treat every deal as announced, not financed.

Amazon disclosed — reportedly for the first time, per The Verge — that its data centers used 2.5 billion gallons of water last year. The disclosure landed just after Seattle enacted a one-year data center moratorium that some of Amazon's own employees had pushed for.

Put that number in context: 2.5 billion gallons is roughly the annual consumption of a city of 25,000 people, drawn almost entirely for cooling. Most large data centers use evaporative cooling towers — the same technology as a power plant cooling system — which consume water by evaporating it into the air. Closed-loop liquid cooling (direct-to-chip or immersion systems that recirculate without evaporating) slashes consumption but demands serious capital.

Regulators in drought-stressed western states now have a concrete number to anchor permitting conditions, and the arXiv preprint estimating data centers may need water equal to New York City's daily use has been circulating in state water board discussions. The signal to watch: whether California's State Water Resources Control Board or Arizona's Department of Environmental Quality cites Amazon's figure in an upcoming permit proceeding. One catch the disclosure buries — it covers only Amazon's own facilities, not the co-located capacity it leases. The real footprint is larger.

FERC committed on April 16 to act by the end of June 2026 in Docket RM26-4-000, the rulemaking governing how large electrical loads — including data centers — connect to the interstate transmission system. That deadline is now roughly two weeks out, and the industry is fixed on one question the trade press has glossed over: will the June action be a final rule, or another Notice of Proposed Rulemaking?

This isn't procedural trivia. FERC says its order will translate ANOPR issues into standards for processing large-load requests — but "translate into standards" is not "finalize rules." A NOPR means the actual framework slips into 2027, and the 2,060+ GW queue keeps growing under current rules through another capacity auction.

One live fight could force exactly that outcome: FERC proposed a 20 MW threshold for "large loads," but commenters argue it's low enough to sweep in ordinary commercial consumers, with alternatives ranging from 30 MW to 300 MW. Worse, PJM has already filed compliance establishing a 50 MW threshold — so a federal rule landing at 20 MW would conflict with PJM before the ink dries. Watch the FERC open meeting calendar for late June. High confidence on the timeline; genuine uncertainty on the outcome.

On June 9, FERC accepted PJM's Expedited Interconnection Track, a process to move up to 20 "shovel-ready" generation projects through faster studies over two years to plug near-term resource adequacy gaps. Commissioner David Rosner's concurrence is the tell: he explicitly says this only works if states speed up siting, permitting, and procurement, because the filing alone won't put "steel in the ground" fast enough.

That reframes the entire large-load problem. The gating constraint is no longer interconnection queues — it's state capacity. The bottleneck has moved from transmission studies to governors' offices and local permits.

What changes if it works: a replicable model where queue priority is paired with state siting commitments, which other RTOs could copy.
What failure looks like: states don't move, the 20 projects stall in permitting, and "expedited" becomes a paperwork exercise. The signal to watch is whether MISO, SPP, or ERCOT files anything resembling PJM's pairing of fast-track studies with state-level commitments.

Germany got there first. AlgorithmWatch reported that the country's data center boom is pushing its power grid to its limits, with Frankfurt — Europe's largest data center hub — at the center. Germany faces a compounded version of the American problem: it's retiring nuclear, integrating intermittent renewables, and absorbing surging data center load, all on a grid never designed for the combination.

The European angle matters stateside for two reasons. First, Germany's stress is already rippling into cross-border flows with France, the Netherlands, and Poland — a reminder that grid reliability is regional, not national. Second, EU operators face stricter energy-efficiency rules than U.S. peers: the EU Energy Efficiency Directive mandates reporting on PUE (Power Usage Effectiveness — total facility power divided by IT equipment power) and water use, creating a compliance cost differential that shapes where hyperscalers build.

Watch whether the EU's sustainability reporting requirements, phasing in through 2027, accelerate liquid cooling adoption in Europe ahead of the U.S. — which would flip the usual assumption that American facilities run further ahead on efficiency. [Source: AlgorithmWatch — German]

A $67 billion utility cradling all of New England's nuclear power like a Florida snowbird's retirement portfolio; Google promising to put its data centers in airplane mode when the grid sweats; and Amazon confessing it drank a small city's worth of water, the week after its own employees told it to stop building. The whole AI infrastructure era now hinges on a FERC clerk deciding whether to type "final rule" or "proposed rule" sometime in the next two weeks — a verb tense worth roughly 2,060 gigawatts.

Stay liquid, stay grounded.

Forward this to the engineer who keeps muttering "but where does the water come from" in siting meetings — they've earned the validation.
