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".

can you recommend or otherwise this software and whether we should pay a 
third share of the cost?

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

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

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
