Which ancillary curves are you referring to? Dana and Doug mark the Northeast and Ercot ancillaries and we do not have ancillaries for every curve.

Rakesh and I talked with Narshima Mistra, ancillary trader at EES. The ancillary curve exists almost every power curve and it's more related to the capacity availability rather than market prices. Obviously it's indirectly related to prices since cost of generation, which is one important factor of constraints in the capacity of generation. So EES has a table of ancillary service price % to generation cost.(Below) I think this table can be used to simulate the ancillary prices by mapping to regional curves after the modification based on the market prices. The problem is the illiquidity of this market. The price is reported once in a month as average point, so the RAC should identify the risk in this market, e.g. is it reasonable to get the daily value at risk. Once again, as long as the daily prices of the ancillary is given, the implementation will be available by doing analysis on the data and making table like below to use in mapping curves. Jaesoo MID - All values are expressed as a percentage of the cost of generation.

Using jumps would be appropriate for them. Jaesoo plans to talk to the trader and come up with more concrete suggestions. How urgent is it to start calculating VAR on them?

The more I looked at the request again, the more I thought that I should be as specific as possible with it so we can get it right the first time. Any questions let me know.
