re : site license for power world richard et al under the new electricity trading arrangments ( neta ) in the uk and looking forward i think it will be increasingly important in modelling market behaviour and transmission related costs to have some form of system model incorporating opf and atc . therefore , in principle i am happy to support option 3 and to pay a 1 / 3 share of the cost . however , before i commit to this particular package , i would like to be comfortable that the generic powerworld software could be suitably customised to capture the special features of neta . i understand marco verreschi who initiated interest from our end is pursuing this with martin lin ( research , houston ) . however , due to commitments next week , and my desire to see powerworld in action etc it is likely to be the following week before he and i can say " lets do it " . michael wilks manager , uk power analytics enron europe ltd tel : ( 44 ) 207 783 2405 richard lewis @ ect 05 / 01 / 2001 15 : 10 to : michael wilks / eu / enron @ enron cc : subject : site license for power world can you recommend or otherwise this software and whether we should pay a third share of the cost ? r - - - - - - - - - - - - - - - - - - - - - - forwarded by richard lewis / lon / ect on 05 / 01 / 2001 15 : 12 - - - - - - - - - - - - - - - - - - - - - - - - - - - lance cunningham @ enron on 20 / 11 / 2000 20 : 02 : 22 to : vince j kaminski / hou / ect @ ect , richard lewis / lon / ect @ ect , tim belden / hou / ect @ ect , tim . heizenrader @ enron . com , kevin m presto / hou / ect @ ect , george hopley / hou / ect @ ect cc : subject : site license for power world gentleman , kevin presto concurred on the purchase of a site license as recommended by vince . what are the thoughts of others ? i am available to demo the package if others would like to see it . thanks , lance - - - - - - - - - - - - - - - - - - - - - - forwarded by lance cunningham / na / enron on 11 / 20 / 2000 01 : 51 pm - - - - - - - - - - - - - - - - - - - - - - - - - - - vince j kaminski @ ect 11 / 10 / 2000 09 : 16 am to : vince j kaminski / hou / ect @ ect , richard lewis / lon / ect @ ect , tim belden / hou / ect @ ect , tim . heizenrader @ enron . com , kevin m presto / hou / ect @ ect , george hopley / hou / ect @ ect cc : lance cunningham / na / enron @ enron subject : site license for power world gentlemen , i recommend that we purchase this package and split the cost 3 ways between 3 power trading desks . i think that we should go for option 3 ( ~ $ 15 , 000 ) . lance cunningham in my group looked at this software package and found it very useful for modeling transmission problems . please , feel free to ask him for technical details in support of this recommendation . vince - - - - - - - - - - - - - - - - - - - - - - forwarded by vince j kaminski / hou / ect on 11 / 10 / 2000 09 : 17 am - - - - - - - - - - - - - - - - - - - - - - - - - - - lance cunningham @ enron on 11 / 09 / 2000 06 : 15 : 14 pm to : vince j kaminski / hou / ect @ ect cc : vasant shanbhogue / hou / ect @ ect subject : site license for power world vince , we have three options to increase our availability across enron for the power world load flow software . option 1 , upgrade to a site license for the load flow software only . price $ 9 , 990 . 00 this would give all of enron the ability to perform load flows , but not determine marginal cost or available transfer capacity ( atc ) because only the optimal power flow ( opf ) version can perform that task . option 2 , site license for the load flow and purchase 1 opf package for walter coffer ' s group . price $ 11 , 240 . this would give all of enron the ability to perform load flows and one other group the ability to determine marginal cost and atc . option 3 , site license for load flows , opf and atc . price $ 14 , 990 . 00 this would give all of enron the ability to perform load flows , marginal cost , and atc . regards , lance
