Calculation of Capacity Benefit Margin (CBM) for NEP

Wherever applicable, New England Power Company (NEP) administers its Open Access Transmission Tariff consistent with the services provided under the NEPOOL Open Access Transmission Tariff, administered by ISO-New England. To the extent that NEP is required to calculate the CBM for transmission services associated with Hydro Quebec Phase I and II, the following, ISO-New England, practice will be employed: It is the current practice of ISO New England Inc. to use 0 MW for CBM when calculating transfer capabilities on its interconnections with other Control Areas. This practice is based on the capability of generation located within New England to reliably meet load and reserve requirements during most hours of the year and on the relatively low usage of NEPOOL ties for supplying loads outside of New England.
