We Built a Live US Power Grid Map: Real-Time Grid Status at /grid
We just shipped something we have wanted for a long time: a live, color-coded map of the US power grid, running at /grid. It shows all 13 EIA regions grouped into the three interconnections that actually make up the American grid, each region wired to its hub, with a real-time terminal feed that logs every status change as it happens. It is free, it needs no login, and it refreshes on its own. This post explains exactly what it is, how it works, how to read the colors, where the honest limits are, and why an offline-AI company built a grid monitor in the first place.
TL;DRA free, live, color-coded map of the US grid at /grid that turns public EIA demand-vs-forecast data into a green-to-red status read for all 13 regions: a heuristic early warning, not an official alert.
What the live power grid map actually is
The US grid is not one machine. It is three. The Eastern Interconnection, the Western Interconnection, and Texas (ERCOT) run largely independently, tied together at only a handful of points. Most people never see that structure. Our map puts it on one screen.
Every region on the map is one of the 13 regions the EIA tracks: California, Texas, the Mid-Atlantic, the Midwest, New England, New York, and the rest. Each one gets a color based on how hard it is working right now. Each is wired to its hub so you can see, at a glance, which interconnection is under load and which is quiet.
Alongside the map is a live terminal feed. Every time a region changes status, the feed logs it with a timestamp. So you do not just see the current state of the grid, you see the grid moving. A region sliding from calm to stressed shows up as a line in the log, not a silent color swap you might miss.
- All 13 EIA regions on one map, color-coded by current stress.
- Grouped into the 3 real interconnections: Eastern, Western, Texas.
- Each region wired to its hub so load is visible at a glance.
- A real-time terminal feed that logs every status change with a timestamp.
- Free, no login, refreshes on its own about every 45 seconds.
How it works under the hood
The map runs on public data from the EIA, the US Energy Information Administration. The EIA publishes hourly electricity demand and a day-ahead demand forecast for each region through its free Open Data API. That gives us two numbers per region: how much power the grid is actually pulling right now, and how much was expected.
The core idea is simple. When actual demand runs close to or above the day-ahead forecast, the grid is working harder than planned, which is the classic setup for stress. So the map's status level is a heuristic: it compares each region's real demand against its own forecast and colors the region accordingly. This is our read, not an official grid alert. We will say that again below, because it matters.
On top of the heuristic, we watch for the real thing. When a grid operator declares an actual emergency, such as an ERCOT energy emergency alert or a CAISO Flex Alert in California, that overrides the heuristic and pushes the region straight to critical. A declared emergency always wins over our math.
The map refreshes about every 45 seconds, and it is built to fail gracefully. If the data feed hiccups or drops, the map holds the last-known state instead of blanking out or flashing everything green. A stale-but-honest read beats a fake all-clear. We deliberately do not scrape poweroutage.us or any outage tracker. This is grid-load data straight from the public EIA source, nothing borrowed.
How to read the colors
The color scale runs green to red, and it is meant to be readable in one glance. Green means the region is calm: actual demand is tracking at or below its day-ahead forecast, so the grid has headroom. As demand climbs against forecast, the color warms toward red. Red means either the heuristic is deep in stress or a real operator emergency has been declared for that region.
Here is the honest part, and please read it: the green-to-red status is a heuristic, not an official grid alert. A region glowing on our map is not the same as your utility telling you to conserve. It is an early, data-driven read that something is trending the wrong way. Treat it as a weather vane, not a siren. When it matters, the authoritative sources are your grid operator and your local utility. ERCOT, CAISO, your ISO, and official alerts always outrank our colors.
One consequence worth stating plainly: because the read is based on demand versus forecast, a region can be pushing real limits with our map still showing calm, or drift warm on a routine day. That is exactly why a declared ERCOT or CAISO emergency overrides the heuristic and pins the region to critical.
- Green means calm: demand at or below forecast, so the grid has room.
- Warmer colors mean demand is running above what was planned for the region.
- Red means deep heuristic stress, or a declared ERCOT or CAISO emergency.
- The colors are a heuristic read, not an official alert from any grid operator.
Why an offline AI company built a grid map
This is not a side quest. It is the whole thesis, drawn on a map.
When the grid is stressed, the internet often wobbles next. Data centers, cell towers, home routers, and the fiber in between all run on power. Push a region hard enough, with a summer heat wave maxing out air conditioning or a severe winter storm running electric heat everywhere, and the failures do not stay in the power sector. Connectivity degrades. And when connectivity degrades, cloud AI goes with it. The smartest assistant in the world is useless if the request cannot leave your house.
We have seen what the extreme end looks like. The February 2021 Texas winter storm left millions of Texans without power for days. The August 2003 Northeast blackout darkened roughly 50 million people across the US and Canada. California has issued Flex Alerts and, in the worst heat waves, rotating outages. None of these were the end of the world, but in every one, the tools people reach for on a phone or laptop got a lot less reliable right when they were needed most. And the US grid is older and more loaded every year, with electrification, EVs, and data centers all pulling harder on aging infrastructure.
That is the exact gap PortableMind is built to close. It is a plug-and-run offline AI on a USB drive. The model, the runtime, and the launcher all live on the stick: plug it into a laptop, click once, and you are talking to a capable AI with Wi-Fi off, running on battery, no account and no connection required. It is 100% local, so your prompts never leave the machine. One-time price, no subscription: CORE at $49 for Windows chat, v1.5 at $79 adding voice and vision, MAX-SPEED for power users, and a $199 PRO Navigator that adds offline GPS. The grid map is the problem stated plainly. PortableMind is one answer to it, the assistant that is still there when the grid, and the internet, are not.
How to use the map day to day
You do not need to babysit it. Open /grid, glance at your region's color, and get on with your day. If your interconnection is green, the grid has headroom. If your region warms up during a heat wave or a cold snap, that is your cue to pay a little more attention: charge your devices, know where your flashlights are, and check your utility's official channel for real guidance.
The terminal feed is there for the people who like to watch the machine move. It is a running log of every status change across all 13 regions, timestamped, so you can see stress build and clear over the course of a day. During a genuine event it turns into a quiet play-by-play of the grid under load.
And if a warm day ever does turn into a dark one, that is the day a battery-powered, offline assistant stops being a novelty and starts being genuinely useful. That is the connection we wanted to make visible.

Conclusion
The US grid is three machines pretending to be one, and most of the time you never have to think about it. The live map at /grid is there for the times you do: a plain, honest read of where the grid is working hard and where it's calm, built on public EIA data and refreshed on its own. It's a heuristic, not a siren. Green to red is an early warning, and your grid operator and local utility are always the last word. We built it because the same forces that stress the grid tend to take the internet with them, and cloud AI right along with it. When that happens, the tool worth having is one that never needed the connection in the first place. Open the map, watch the feed, and know what you'd reach for on a red day.
Open the live power grid mapFrequently asked questions
Long-tail answers for the search queries around this topic.
- Is there a live power grid map for the US?
- Yes. Our live US power grid map at /grid shows all 13 EIA regions grouped into the three interconnections, color-coded by current stress and refreshed about every 45 seconds. It is free and needs no login.
- Where does the grid map get its data?
- It uses public data from the EIA, the US Energy Information Administration, which publishes hourly electricity demand and a day-ahead demand forecast for each region through its free Open Data API. It does not scrape outage trackers like poweroutage.us.
- What do the colors on the power grid map mean?
- The scale runs green to red based on how each region's actual demand compares to its own day-ahead forecast. Green means demand is tracking at or below forecast; red means demand is running far above it, or a real ERCOT or CAISO emergency has been declared for that region.
- Is the grid status an official alert?
- No. The green-to-red status is a heuristic that compares real demand to the day-ahead forecast. It is an early, data-driven read, not an official grid alert. For authoritative warnings, always check your grid operator and local utility.
- How often does the live grid map update?
- About every 45 seconds. If the data feed drops, the map holds the last-known state rather than blanking out or showing a false all-clear.
- How are the three US interconnections different?
- The US grid is split into the Eastern Interconnection, the Western Interconnection, and Texas (ERCOT). They run largely independently and are tied together at only a few points, which is why the map groups regions by interconnection.
- Why does an offline AI company track the power grid?
- Because when the grid is stressed, the internet often wobbles next, and cloud AI goes with it. PortableMind is a plug-and-run offline AI USB that runs on laptop battery with Wi-Fi off, so it still works when the grid and the connection do not.
