Renewable Energy Forecasts for CAISO Region & Sites – Sample
收藏资源简介：
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. Please contact us using the Contact Vaisala link in the listing if you would like to purchase a regularly updated data feed for the CAISO region. Tables included: LATEST 7-DAY FORECAST LAST 2 DAYS ESTIMATED ACTUAL POWER REGIONAL SITES METADATA Fields included: LATEST 7-DAY FORECAST - NAME — renewable energy project name - TIME — date and time for the forecast - FORECAST — forecasted power in MW - INTERVAL — the time between forecasts - TIME ZONE — local time zone for time values - FORECAST CREATION TIME — date and time the forecast was created - MODEL INITIALIZATION TIME — date and time when the forecast model was initiated LAST 2 DAYS ESTIMATED ACTUAL POWER - NAME — renewable energy project name - TIME — date and time for the observation - ESTIMATED ACTUAL POWER — estimated actual power in MW - INTERVAL — the time between observations - TIME ZONE — local time zone for time values - FILE CREATION TIME — date and time the file was created REGIONAL SITES METADATA - NAME — renewable energy project name - ALTERNATE_NAME — alternative name - EIA_PLANT_CODE — U.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 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.
