ABOUT
Simulations of site-specific forecasts that would have been generated over a past period in operational conditions
Project developers, EMS providers, plant operators and portfolio managers need to access historical production forecasts of projects before commissioning. This is possible through our simulations of retrospective forecast (hindcast, also called backcast).
These simulations provide a reliable representation of forecasts that would have been produced by our SteadyMet and SteadySat products over a past period of one year or more. They thus allow you to anticipate the risks associated with one or several project(s) and maximize their income(s).
Backcasting is also useful after commissioning, to quickly evaluate the performances of operational forecasts without having to perform any long-term trial.
Steadysun is able to perform these simulations at your project sites anywhere in the world.
