For each combination base/peak and term, a nominal or multiplier is associated, depending on the number of hours of the delivery period (for example: quarterly base 90 days with a 23 hour day, quarterly base 91 days with 24 hours, quarterly base 92 days with 24 hours, etc).
The number of hours depends on: the term of the contract, the calendar and the relevant hours of each contract. For example, for base, wind profile (sonly weekly and daily) and Mini contracts we have:
|Delivery Period||Specific Period||Days||Nominal (MWh)||Nominal Mini(MWh)|
|Week||Whole - Without time change||7||168||16.8|
|Whole - March with time change||7||167||16.7|
|Whole - October with time change||7||169||16.9|
|Weekend - Without time change||2||48||4.8|
|Weekend - March with time change||2||47||4.7|
|Weekend - October with time change||2||49||4.9|
|February (leap year)||29||696||69.6|
|January, May, July, August and December||31||744||74.4|
|April, June, September and November||30||720||72.0|
|First (leap year)||91||2,183||218.3|
Logically, contracts with the same delivery period (for example annual swaps and futures) have the same nominal.
|Delivery Period||Specific Period||Days||Nominal (MWh)|
The nominal for peak monthly, quarterly and annual contracts will depend on the number of days in the delivery period that are not Saturdays and Sundays.
