April 1 — The commission amended staff’s proposed order by excluding 820 MW of DC tie import capacity from the Eastern Interconnection as “not being appropriate” in determining the combined entity’s market share. Combined with a previous ruling that excluded a 915-MW gas plant from market power calculations, Vistra’s generation arm, Luminant, would no longer be required to divest itself of at least 1,281 MW of capacity.
