Vaisala Xweather

Vaisala Xweather provides accurate energy forecasts for utility-scale wind and solar projects in North American RTO/ISO regions. This high-quality data set for wind energy projects in the Electricity Reliability Council of Texas (ERCOT Wind) region helps asset owners, project managers, and energy traders make confident, data-driven decisions at the site-specific and regional level to effectively manage investments, reduce future risks, and gain a competitive edge in energy markets. Look ahead with 10-day power forecasts at 1-hour intervals at the plant and regional level for real-time and day-ahead markets.

Look back at site-level estimated actual power data in 5-minute intervals for the last two days. Xweather combines cutting-edge weather and environmental modeling, robust data science, and powerful supercomputing to produce accurate energy forecasts and actual power estimates for wind and solar projects. This sample data set contains 1 day of forecast data and 1 day of estimated actual power data from April 23, 2023, for all sites in the ERCOT Wind region.

Please contact us using the Contact Vaisala link in the listing if you would like to purchase a regularly updated data feed for the ERCOT Wind region. S. Energy Information Administration project ID MAX_CAPACITY — project capacity in MW MODEL — turbine model used in wind projects ONLINE_DATE — operational start date LATITUDE — location of the project LONGITUDE — location of the project STATE — location of the project COUNTY — location of the project SUBGROUP — subgroup designation within the RTO/ISO region DATA FORMAT AND GRANULARITY Data is provided for all projects and sites within the ERCOT Wind region.

The data set includes three CSV files. The first file contains site-specific metadata about each project in the region such as name, location, and capacity. The second file provides a 10-day energy forecast (240 hours) in 1-hour intervals for each site in the region and a forecast for the ERCOT Wind region as a whole.

The third file contains the estimated actual power output from each site and for the region as a whole over the last 2 days in 5-minute intervals. SOURCES The total actual power for the region comes from ERCOT. The estimated actual power for each site in the region and the 10-day energy forecasts are produced using Vaisala's proprietary blend of numerical weather prediction trained models, statistical data modeling, and sophisticated machine-learning algorithms.

Wind energy estimates and forecasts combine the actual operating characteristics of each project with the most advanced weather forecasts available. Solar power estimates and forecasts combine each project’s unique environmental considerations with superior irradiance forecasts.
