As part of the Snowmass/P5 upgrade process, Fermilab leadership has proposed an upgrade plan for the Fermilab proton complex known as Accelerator Complex Evolution (ACE). We will present the details of the ACE upgrade plan, with a special focus on the opportunities for near-term and next-generation beam experiments at Fermilab. The first phase is the ACE is the Main Injector Ramp & Targetry (ACE-MIRT) upgrade and the second phase is Booster Replacement (ACE-BR) upgrade. The opportunities for future experiments have been categorized as “spigots” and the range of energies, intensities, and pulse structures potentially available will be discussed.
