Deficiency Case – In the summer of 2004, the MPSC found the Detroit Edison Company’s summer capacity plan to be deficient and reflected less than thorough planning, falling short of the Commission’s expectations. Subsequently, the Commission granted limited authority to the Company to purchase electric energy capacity from two of its affiliates during that summer. This circumstance was discussed in two different cases – one case for the deficiency finding (Case No. U-14109) and one case for the authorization of purchasing electric energy capacity (Case No. U-14138).
