Probably the biggest risk is the loss of "Spinning Reserve". At any moment on any day a large base load power plant unit can trip offline. Spinning Reserve is generation that is online below maximum capacity, with the ability to rapidly increase output. For example if on a hot summer day just one 850 Megawatt unit at Calvert Cliffs trips for whatever reason, you would need over 40 other units already online that can each instantly contribute another 20 Megawatts each. Joe Biden, Jennifer Granholm, and John Kerry will all deny their responsibility for the tragedy they have created. Without a doubt the doodoo will hit the windmill this year.

Optimizing Reserves
Introduction
Operating reserves are needed to ensure that additional energy is available in response to numerous
possible system events. “Spinning reserves” – one type of operating reserves – are the unloaded portion
of generators that are online already and can quickly increase their output to their maximum ratings to
meet changes in demand. Other operating reserves can be provided by offline generators that an
operator can turn on when needed (known as 10-minute “quick start” units) but which cannot respond
immediately as spinning reserves. Operating reserves help to restore balance to the system following
large losses of resources, such as the balancing authority’s largest single generating contingency. Both
kinds of reserves are critical to reliability of the grid and should be optimized.
