Where does your electricity come from?

wherepower is a free map of the US power grid. Type in any US address and it shows the power plants and high-voltage transmission lines around it, the electric utility and grid operator that serve it, and what that grid is generating right now.

How to use it

1. Enter an address, or use your current location. Any US street address works.
2. See your grid. The panel names your electric utility and the grid operator (balancing authority) that keeps supply and demand matched in your area, such as PJM, ERCOT or CAISO.
3. Check the live fuel mix. A bar shows what share of your grid's power is coming from natural gas, nuclear, coal, hydro, wind, solar and storage in the latest reported hour.
4. Explore power plants near you. Pick a radius of 10, 25, 50 or 100 miles to see the plants nearby, their total capacity, and the split by fuel. Click any plant on the map for its details.

Zoom in to see transmission lines of 69 kV and up, with substations where they meet. You can filter the map by fuel, show planned plants as hollow circles, and switch between light and dark themes.

Where the data comes from

Everything on the map comes from public US government datasets:

• Power plants: the EIA-860M monthly generator inventory from the US Energy Information Administration, covering about 14,700 operating plants with units of 1 MW or more, plus planned ones.
• Live fuel mix: the EIA Hourly Electric Grid Monitor (EIA-930), which reports generation by fuel for each grid operator.
• Utilities: EIA-861 electric retail service territories.
• Transmission lines: the HIFLD US Electric Power Transmission Lines dataset.
• Addresses: the US Census Geocoder. Map tiles are from OpenFreeMap and OpenStreetMap contributors.

Frequently asked questions

Which power plant powers my house?

No single plant does. Electricity from every plant on a grid flows into the same network of lines, and the grid operator balances all of it together. The most honest answer to "where does my power come from" is your grid operator's fuel mix, which is what wherepower shows. The nearby plants show what is generating close to you.

What is my grid's fuel mix right now?

Enter your address and look under "Generating right now, by fuel". It shows the percentage from each fuel and the total output for your grid operator. EIA publishes this data with a delay of about a day, so the hour shown is usually yesterday's.

How do I find power plants near me?

Search your address or tap the location button, then choose a radius. The panel lists total capacity within that distance by fuel, and the map shows each plant as a circle sized by capacity and colored by fuel.

Who is my electric utility?

wherepower looks up your address in the EIA's utility service territory maps and shows the utility's name, its type (investor owned, municipal or cooperative) and its customer count. Where territories overlap, other utilities that serve the area are listed too.

wherepower covers the United States only. Plant data is refreshed monthly; transmission lines and utility territories are cached and may lag recent changes.
