AI summary Nova Scotia Power Inc. (NSPI) uses 'billed' sales rather than 'accrued' sales for load forecasting due to the longer historical data availability. Billed sales reflect energy billed to customers, while accrued sales represent actual energy generated. System losses, including transmission/distribution losses (4% in municipal areas) and unbilled sales, are estimated at 6.6-6.7% of total Nova Scotia energy requirements.

Figure 1 Annual Net System Requirement p. pp. 10-14
Figure 1 Annual Net System Requirement In addition to annual energy requirements, NSPI also forecasts the peak hourly demand for future years. The forecast methodology uses forecast energy requirements and expected load shapes (hourly cons...

AI summary NSPI forecasts annual energy and peak hourly demand using historical load shapes adjusted for changes like new equipment. Net System Peak is projected to decline by 1.5% annually until 2021 due to DSM programs, contrasting with a 1.0% growth rate without DSM. This reflects the impact of demand-side management on reducing peak demand.

AI summary The document discusses generation plans for both No DSM and With DSM cases, including specific loads and firm capacity. It mentions that transmission avoided costs are considered minor compared to energy and capacity costs. DSM programs are not geographically directed, and their impact on distribution upgrades is limited. Both plans account for environmental and system constraints, including greenhouse gas regulations.
