  Poisson-Lie T-duality and plurality are important solution generating
techniques in string theory and (generalized) supergravity. Since
duality/plurality does not preserve conformal invariance, the usual beta
function equations are replaced by Generalized Supergravity Equations
containing vector $\mathcal{J}$. In this paper we apply Poisson-Lie T-plurality
on Bianchi cosmologies. We present a formula for the vector $\mathcal{J}$ as
well as transformation rule for dilaton, and show that plural backgrounds
together with this dilaton and $\mathcal{J}$ satisfy the Generalized
Supergravity Equations. The procedure is valid also for non-local dilaton and
non-constant $\mathcal{J}$. We also show that $Div\,\Theta$ of the
non-commutative structure $\Theta$ used for non-Abelian T-duality or integrable
deformations does not give correct $\mathcal{J}$ for Poisson-Lie T-plurality.
