Summary: We provide a new description of the Pieri rule of the homology of the affine Grassmannian and an affine analogue of the charge statistics in terms of bounded partitions. This makes it possible to extend the formulation of the Kostka-Foulkes polynomials in terms of solvable lattice models by A. Nakayashiki and Y. Yamada [Sel. Math., New Ser. 3, No. 4, 547–599 (1997; Zbl 0915.17016)] to the affine setting.
