The energy value up to which all energy states are full at absolute zero (0K) and above which all states are empty is known as the Fermi energy or the Fermi level. Electrons, being fermions, fill the lowest available energy states due to the Pauli exclusion principle; the Fermi level represents the highest of these filled states at 0K.
