The uncertainties around solar power are well understood — when the sun doesn’t shine as much as expected, power grids that rely heavily on that generation must turn elsewhere to meet consumer demand. And while a shortfall in solar generation can be challenging to navigate, the difference between actual and forecast levels is typically only a few percentage points and power grids are usually ready and able to make up any difference. But what happens when the sun is largely obscured by the moon for several hours across a wide swath of the country? In today’s RBN blog, we’ll discuss the impact of the October 14 partial eclipse, preview the path of the April 8 total eclipse, and outline the steps being taken to ensure that power grids are ready for it.
