I have emailed a new spreadsheet to rcmanteno with the request to have it posted on our website. This spreadsheet is an attempt to compare Mirant�s operational performance compared to all the other coal fired power plants in Maryland for the years 1997 through 2004, inclusive. The only plant that I did not consider was the RP Smith station, which has only two units still running; unit 3 at 34 MW went commercial in 1947 and unit 4 at 75 MW went commercial in 1957. One other exception is a cogen owned by AES. Given that it is a cogen it has significantly other operating issues compared to a basic power plant. Other than that, the State of Maryland has coal fired stations owned by only two entities, Mirant and Constellation. The methodology that I employed was to take the three Mirant sites, Dickerson, Chalk Point, and Morgantown and compare them to plants of similar age and output power rating. The spreadsheet has data obtained from the web pages of US EPA, US DOE-EIA and EPRI. The only thing that I added was the calculation, which is shown in blue font to represent my assessment as to the average power level expressed in MW while that particular unit was operating. The purpose of this exercise was to determine an approximate plant utilization. To accomplish that I had to make some professional judgements as to what each unit�s heat rate ( efficiency ) might be. A very strong word of caution to anyone looking at my calculated average power level. This is a qualitative analysis not quantitative. It is meant to compare Mirant�s sites with its peers. Thus, it is important to look at a particular unit to see if it uses a super critical boiler or sub-critical boiler. Current accepted industry averages for current and new units are 34-37% for sub-critical and 37-41% for supercritical boilers.
