Quantifying uncertainty to produce more useful solar generation forecasts
Renewable energy firm PowerUQ advocates for the use of Uncertainty Quantification (UQ) in solar project analytics to combat the widespread issue of performance shortfalls. By incorporating a wider range of variables and providing probability scenarios like P50 and P90, UQ aims to make solar generation forecasts more useful and accurate over a project’s long lifespan.

Grid operator PJM reports progress on interconnecting new generation as capacity costs surge
PJM said it agrees with many of the recommendations for speeding transmission interconnection made by the nonprofit group RMI, and reported it has completed 600 interconnection studies in less than 22 months under its current interconnection study process. Even so, a GridLab report says PJM would have substantially lower capacity costs next year if a modest portion of renewable and storage projects in PJM’s queue had been set to reach operation by then.
