Recent experiments have shown that changes in plasma behaviour are influenced by the application of electrostatic fields in both divertor and limiter configurations. In order to investigate the impact of biasing on scrape-off layer profiles, the B2 code is extended to compute electric fields, electric currents and diamagnetic and E x B particle drifts. The extended B2 code (EB2) is able to provide stable and converged solutions with only a slight increase of computing time. The effect of the additional variables for grounded, floating and poloidally biased divertor plates is investigated for a low power divertor configuration. The introduction of a neoclassical expression for the radial current density provides the opportunity to obtain the electric potential inside the last closed flux surface.
