Product Provisions for Use with the
EEI Master Contract
ERCOT RUC Language
following Amendments address ERCOT's planned assessment of hourly and day-ahead
Reliability Unit Commitment "RUC" charges in the Nodal Market for firm physical
deliveries which are scheduled after the relevant hourly or day-ahead deadline
(the day-ahead RUC deadline is currently 2:30 pm).
The first document,
Version 1.0 of the Amendment, clarifies that the scheduling time corresponds to
the time in which the ERCOT runs the day-ahead and hourly RUC markets. The
second document, Version 2.0 of the Amendment, contains a more defined
scheduling timeline than Version 1.0 for transactions that must be scheduled in
the HRUC. Under Version 2.0, transactions that are entered into in the first
half of each hour must be scheduled by the next hour's HRUC deadline. For
example, if the parties enter into a transaction at 8:15, they would need to
schedule the transaction before the start of the first HRUC after 9 am.
Transactions that are entered into during the second half of each hour (i.e.,
up to 30 minutes prior to the top of each hour) must be scheduled, not by the
next hour's HRUC deadline, but rather by the one after that. For example, if
the parties enter into a transaction at 8:45 instead of 8:15, they would need to
schedule the transaction prior to the first HRUC after 10 am. Version 1.0 of
the amendment has a more generalized HRUC scheduling deadline. Parties may find
the more specific deadlines in Version 2.0 to be advantageous by comparison to
Version 1.0. The third document is a redline showing the difference between
Versions 1.0 and 2.0.
An optional definition may be used with the Master Contract for transactions
involving energy delivered at a California Delivery Point. This traded product
is commonly known as "CAISO Energy." The following entities have agreed to use
this definition: American Electric Power, Calpine, Constellation Power Source,
Dynegy, Edison Mission Energy, El Paso Merchant Energy, Enron, Mirant, PG&E
National Energy Group, Reliant Energy Services, Southern California Edison,
Tractebel, and the Williams Companies.
