Renewable Energy Forecasts for CAISO Region & Sites – Sample

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 the California ISO (CAISO) 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 7-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 for sites in the CAISO region in our database.

All data provided is interval ending.

DATA FORMAT AND GRANULARITY

Data is provided for projects and sites within the CAISO region in our database.

The data set includes three CSV files.

1) The first file contains site-specific metadata about each project in the region such as name, location, and capacity.

2) The second file provides a 7-day energy forecast (168 hours) in 1-hour intervals for each site in the region and a forecast for the CAISO region as a whole.

3) 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 CAISO. The estimated actual power for each site in the region and the 7-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.
