Please see attached spreadsheet. 2. Ditto. 3. Attached spreadsheets have some info. I am working on more detail for you. 4. I am seeking response from TPS engineering. 5. I am seeking additional info from TPS environmental. 6. See spreadsheets. No duct firing. - Frank P.S. On the Heat Rate Spreadsheet, look@ the 2x1 and 1x1 tabs (it is a work in progress). What about the 'operational tools' you referred to that you may have on the shelf and can provide to me? >>> "Curry, Mike" 04/11/01 01:54PM >>> Frank, here is the list of operational info that I think would be helpful to our team: 1) Ramp Rates for plant (ramp up and down) - zero to 139 MW (this is probably N/A due to permit concerns?) - 140 to 230 MW - 231 to 280 MW (this is probably N/A due to permit concerns?) - 281 to 460 MW 2) Heat Rate Curves - vs. output - vs. Temp. / Rel. Humidity 3) Start charge (in MMBtu) - please define each, i.e. cold start means plant has been down x hours - cold start - warm start - hot start 4) Is there a maximum number of starts per year? 5) Is there any permit limitations other than below? - In 1x1 must operate only between 140 MW and 230MW approx. to stay within permit limits? - In 2x1 must operate only between 280 MW and 460MW approx. to stay within permit limits? - Annual limit on run time or tons of emission? - What is a violation, is it any deviation or must the deviation occur for a min. amount of time? 6) Operational limits - In 1x1 operates between 140 MW and 230MW approx. - In 2x1 operates between 280 MW and 460MW approx. - Any other level that can be operated? Any duct firing? Thanks for your assistance with these, - Mike - Frontera APRIL 2001 Mike Curry.xls - Frontera Heat Rate Charts FB.xls
