Solar Energy Forecasts for PJM region

Vaisala Xweather provides accurate renewable energy forecasts for utility-scale wind and solar projects in North American RTO/ISO regions.This high-quality data set for solar energy projects in the PJM 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.<br/>
- Look back at site-level estimated actual power data in 5-minute intervals for the last 24 hours.<br/>

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 data set is updated daily with the latest 7-day forecast and the last 24 hours of estimated actual power data, for all sites in the PJM region in our database.Your subscription includes access to additional data visualization tools and resources on the Vaisala Xweather renewable energy portal. Please see [https://www.xweather.com/renewable-energy/forecasting](https://www.xweather.com/renewable-energy/forecasting) for details.Tables included:

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 24 HOURS ESTIMATED ACTUAL POWER

- NAME — renewable energy project name

DATA FORMAT AND GRANULARITY Data is provided for projects and sites within the PJM region in our database.The data set includes three tables.<br/>

1. The first table provides a 7-day energy forecast (168 hours) in 1-hour intervals for each site in the region and a forecast for the PJM region as a whole.<br/>
2. The second table contains the estimated actual power output from each site and for the region as a whole over the last 24 hours in 5-minute intervals.<br/>

SOURCES<br/>The total actual power for the region comes from PJM. 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. Solar power estimates and forecasts combine each project’s unique environmental considerations with superior irradiance forecasts.
