6 (f) Muskrat Falls, Labrador Island Link, and Maritime Link have been operating reliably in 7 steady state for some time. NS Power believes that the probability of Maritime Link energy 8 import deviation from forecast is now similar to th...

AI summary NS Power discusses the reliability of energy imports from Muskrat Falls, Labrador Island Link, and Maritime Link, noting that deviations are now comparable to New Brunswick. They use a combination of forecasts and historical data for surplus energy predictions. Increased fleet flexibility from SO2 CoV reduces the cost impact of deviations, allowing reliance on coal-based generation instead of higher-cost imports. PHP load exclusion is noted in marginal cost forecasts.

Billing demand is determined based upon the following formula: Billing demand = $$(PR/(1+PR) min(CD, CCF GC)) + (CD - min(CD, CCF GC))$$ Where: PR is Planning Reserve (based on NPCC planning criteria, i.e. 20% or as updated) GC is the thir...

AI summary The document provides a formula for calculating billing demand, incorporating variables such as Planning Reserve (PR), generating capacity (GC), Contract Demand (CD), and the capacity contribution factor (CCF). It distinguishes between dispatchable and non-dispatchable generation and references specific tariffs and planning criteria.
