Renewable energy forecasting
Weather is the fuel for renewable energy. That’s why accurate weather forecasts are essential to asset owners, project managers, energy traders, and power schedulers. You need weather intelligence to schedule, buy, and sell with confidence, which requires forecasts not only for individual wind and solar projects but across vast geographic regions too.
The Situational Awareness tool forecasts the key weather parameters for renewable energy globally and provides an intuitive, map-based visualization of renewable energy production across the major electricity trading markets in the United States and parts of Canada. You can look ahead with an animated six-day forecast or review previous forecasts from up to 60 hours in the past.
Wind and solar forecasting
See wind speed and direction at 100 meters above ground level for wind projects and global horizontal irradiance (GHI) at ground level for solar projects. Other layers include cloud cover, atmospheric pressure, precipitation rate and type, snow depth, and air temperature at 2 m.
Energy production forecasting
Small circles mark the location of energy projects on the map. The color indicates the project’s estimated energy output as a percentage of its nameplate capacity. Moving your mouse over a project reveals more details.
