Globally the utility scale segment of the solar industry is growing at an exponential rate.  And while this is exciting for all of ur working toward the solar powered future, many challenges are created when operating these assets in our energy networks and markets.  One key enabling technology for successfully integrating these incredible volumes of new solar facilities into our electricity system is solar farm forecasting.

Solcast delivers on utility scale solar power forecasts through our global rapid update forecasting system to accurately track and forecast cloud cover and pairing that capability with our tuning technologies which learns the individual behaviours of each solar farm. 

Our rapid-update utility scale solar farm forecasts update every 10 or 15 minutes and extend out to 7 days ahead at 5, 10, 15 or 30 minute time granularity.  We operate this technology for thousands of utility scale solar farms around the globe, delivering forecasts via the Solcast API service.

Image Description:  Pictured here is a sample of our utility scale solar farm forecasting product, including live accuracy reporting as available via the Solcast API. The user can visually compare the SCADA actuals (orange) to the Solcast satellite-derived estimated actuals (blue line) and the Solcast forecasts (white grey line).

To take advantage of our tuning technology, you can POST your realtime SCADA data to the Solcast API service or simply provide us with an extract of 3-6 months of historical data.  

Proven customer use cases for the utility scale solar farm forecasting include: 

  • Solar farm operators reducing their market penalties and curtailment
  • Energy market operators modelling future solar farm uptake scenarios, and then grouping solar farm forecasts over a set region
  • Network service providers reviewing utility scale solar farm connection agreement with high-resolution historical data (5-10 minute)
  • Energy generators applying Solcast 0-7 day solar farm forecasting for the smart management of attached storage devices

If your use case includes very-short term forecasting or if you have a sky imager device operating onsite, we can update the first 60 minutes of the forecast every 1 minute through our super-rapid update product.  For this one, you’ll have to contact us for more information!
