I will discuss formulas of generators of the center of the completed quantum affine algebra in type A at the critical level. They are associated with primitive idempotents of the Hecke algebra and parameterized by Young diagrams. The Harish-Chandra images of the Sugawara operators are identified with the eigenvalues of the operators acting in the q-deformed Wakimoto modules. This recent joint work relies on suitable q-versions of the symmetric group and new ingredients of the Hecke algebra.
