CEAtlas maps 214,598 power plants, 688,039 transmission-line features and 701,304 substations next to live markets, our nodal price forecasts for the US and our zonal forecasts for GB and Europe. Its site screens answer in minutes the questions a consultant usually takes weeks over.
Map counts as served on 30 September 2026.
The United States tab gathers the layers a US site screen starts with, grouped by topic: who serves an area, what is built and what is planned, the fuel supply, and the land and hazards around a site. It is built from public data sources, most of them openly licensed. Counts as served on 30 September 2026.
2,919 US electric utility territories, with 2024 customers, sales, revenue and average price from EIA-861 for 2,904 of them, and 1,261 gas-utility territories, 88.5% of them with EIA-176 2024 customers and prices. Also ISO/RTO footprints, 68 active balancing authorities, reliability coordinators, interconnections, FERC regions and 43 electricity border crossings to Canada and Mexico. One click lists every boundary under the point. Free.
77,379 US wind turbines (US Wind Turbine Database v9.0, June 2026) and 7,841 in Canada, grouped into 2,167 projects. Click a turbine for its year, make and model, hub height and rotor. The real outlines of 6,611 US solar farms of 1 MW and up (USPVDB v4.0, April 2026), with planned units drawn as rings on the power-plant layer. Free.
3,250 gas facilities: compressor stations, processing plants, storage fields, LNG terminals, hubs and border crossings. 47,088 US and Canadian mines, USGS coal fields, EIA’s 50 shale and tight-oil plays, and modelled rock temperature 3 km down (modelled, not measured). Free. Eight gas pipeline projects built since 2020 and 2,648 large industrial emitters (EPA greenhouse-gas reporting, 2023) are free for now.
Federal land (PAD-US 4.1), 19 BLM Solar Energy Zones and Section 368 energy corridors, 45 BOEM offshore wind leases, county borders, population density, and The Nature Conservancy’s Power of Place-West exclusion categories for 11 western states (schematic scenario-analysis data, not a siting determination). Free. The FEMA National Risk Index for 3,232 counties across 18 hazards and USFS wildfire hazard potential are free for now.

EIA’s August 2026 generator inventory (EIA-860M) lists 288.7 GW as planned or under construction: 98.8 GW under construction and 190.0 GW planned, including 122.4 GW of solar, 69.4 GW of gas and 64.5 GW of batteries (the total includes 0.2 GW in Puerto Rico). The dates are the developers’ own, not a CEAtlas forecast. It refreshes monthly and is free with no sign-in, in the Fleet Census.
Between the July and August 2026 EIA-860M filings, 38 plants (3,252.7 MW) began operating, 23 (1,509.4 MW) were newly planned, 7 (1,027.5 MW) were cancelled or postponed, and 231 moved their planned dates. Shown plant by plant on the map and in the Fleet Census. Free.

The 24/7 CFE study asks whether a data centre at a given site could run on clean power every hour of the year. It dispatches wind, solar and batteries against your load chronologically through all 8,760 hours, repeats that for each of 86 weather years, and reports P50 and P90 bands, storage sweeps and a PDF you can hand to a board.
The connection study gives the required voltage, the nearest adequate line, N-1-secure usable headroom, published DNO capacity where it exists, curtailment risk, an indicative upgrade cost and a 0–100 Connection Difficulty Score.
Scenario Studio (Enterprise) lets you add or remove assets and re-solve the capacity expansion to see what gets built, how flows change and what happens to prices. It covers Oregon today, on a 752-bus model, and more regions are on the platform roadmap.
On Desk and up, CENovaSage’s nodal forecasts cover all nine US regions, hourly for today and tomorrow: about 20,000 buses on one map, with per-bus prices, line flows and unit dispatch. GB and Europe come from CEGridSight’s zonal model four times a day, 14 days out, across 17 GB transmission zones and 26 EU bidding zones.
The weather store holds 86 years of hourly wind speed and irradiance at any coordinate on Earth (1940–2025). From it the map serves mean capacity factors, 12×24 profiles, full hourly downloads, P50/P90 and trend. Every year, the P50/P90 and the trend are free on the map.
We re-modelled 583 US onshore wind plants (87 GW, 2019–2024) at each plant and compared the result with EIA-923 metered generation. Across the 570 plants with true monthly meters, the median correlation of monthly shape is r = 0.877. That measures how closely the model follows each plant’s month-to-month pattern; it is not a percentage accuracy. Metered output comes in at a median 82% of the modelled level, and we publish that too. Solar against PVGIS gives an hourly r of 0.95 for fixed-tilt and 0.90 for trackers, and wind against MERRA-2 a median annual-speed r of 0.89 at 36 sites. The validation was run in July 2026 and is re-checked weekly on the free accuracy page.
The Data Assistant is a tool-using analyst over the full dataset. From chat it can screen connections, look up live prices and run a full 8,760-hour 24/7 study. Every figure it gives is source-cited, and it declines to answer rather than guess.
Pipeline mode takes a CSV of candidate sites, scores each one for Connection Difficulty Score, headroom, suitability and nearest substation, and returns a ranked export.
With no card: the global map, 29 of the 33 United States layers, the Fleet Census with the US build pipeline and plant changes, and wind and solar resource at any coordinate (86-year mean and median, every year since 1940 on the map, P50/P90, variability and trend). A free account, email only, adds full hourly 2025 at any coordinate on the map and as a download, the 12 × 24 profile, the annual bars and one site analysis.
The Fleet Census is free for everyone. It profiles the US, GB, EU and world power fleets by age, additions, retirements and build pipeline, with per-plant lifecycle records and measured output where meters exist. The US pipeline and the monthly plant changes refresh with each EIA-860M release.
