2. Agenda Review of service area and load/generation distribution
Peak demand breakdown by area and season
High-level discussion of Resource Planning versus System Planning forecast methodologies
Future planned reinforcements
Uncertainty around new technologies

3. FortisBC Service Area Overview

4. FortisBC Winter Peak – MW by area

5. FortisBC Summer Peak – MW by area

6. Load Forecasting Methodologies
Resource Planning versus System Planning forecasts
Resource Planning – “top down” forecast
Represents entire system as a single load
Typically weather normalized
System Planning – “bottom up” forecast
Used for feeder, substation and area system planning
Based on actual peaks (typically recorded during weather extremes)
Both methods were reviewed extensively during the 2012 Integrated System Plan (ISP) development
Both methods are linked:
System Planning area forecasts are dependent on the Resource Planning forecasts

8. Load Forecasting Uncertainties
Some areas of uncertainty that could be significant:
Plug-in electric vehicles
Distributed generation resources
Impact of DSM on system peaks (at weather extremes)
Some impacts result in load increases, others in decreases
What will be the net effect on the system?
None expected in near term
Expected load increases/decreases are outweighed by normal year-to-year load variation due to weather
From a Resource Planning perspective will be covered off in the high-low scenario simulations and analysis
