The grids

Dozens of balancing authorities run the lower 48, and the same federal feed reports every one of them. Aquadrio reads that feed on the hour and asks each grid one question: clean enough, right now, to certify compute? Most hours, almost everywhere, the answer is no. This page is where that answer lives in public.

Reading the board

Each tile is one balancing authority. The rail marks its latest-published carbon intensity against the one gate every meter uses: 100 grams of CO₂ per kilowatt-hour, the same line the RCC Standard publishes. A gate reads open or shut from the grid data alone. Where a meter is installed the tile says so, and the certification calls live in that meter's cockpit; an open gate elsewhere certifies nothing, because nobody measured any compute there. The feed is delayed, and each tile carries its own measured delay rather than a promise of real time.

How often each gate opens

The board shows one hour; this table shows the years. For every authority, the share of published hours whose grid cleared the gate, computed from a seven-year backfill of the same federal feed. On most grids the honest number starts with a zero. On the hydro columns of the Pacific Northwest it does not, which is why the next meters are going there.

Share of published hours whose generation-mix carbon intensity was at or under 100 gCO2/kWh (the clean gate alone; not the meters' full-stack rarity).

* Demand is net of rooftop solar (EIA-930): midday figures understate total solar. Footprint: CAISO balancing authority.

Source: U.S. Energy Information Administration, Form EIA-930 (Hourly Electric Grid Monitor), public domain; seven-year hourly backfill, vintages and revisions as published; computed 2026-07-06T21:12:12Z.

Method

Data: EIA-930 Hourly Electric Grid Monitor (U.S. Energy Information Administration, public domain), served on its published lag and labeled with the measured delay. Carbon intensity is computed from each authority's reported fuel mix with the factor table published in the RCC Standard; the meters run the same computation on the same table. Water intensity is consumption, never withdrawal, on a cooling-typed regional basis with the basis named on every figure. Historical rates count the carbon gate alone; a meter's certification additionally requires the water gate and a measured job, so the table is an upper bound on what any grid could certify.
