    Abstract:

This paper is devoted to the approximation by a piecewise linear finite element method of a noncoercive system of elliptic quasi-variational inequalities arising in the management of energy production. A quasi-optimal $ L^{infty}$ error estimate is established, using the concept of subsolution.
