Letter to the Editor
Joseph Bowring, PJM Market Monitor: ”Pondering PJM's Energy Price Run-Up” by Howard Spinner of the Virginia State Corporation Commission staff raises the question of whether the observed increase in PJM average system prices in the second half of 2005 was the result of fuel-price increases and increased loads, or the result of market power. The results reported in the Spinner article are incorrect; see PJM Energy Prices—2005: Response to Howard M. Spinner Paper.”
