HOW TO USE THIS REPORT

Overview

This report contains recent historical information on the level of utilization of firm transportation ServiceAgreements on the NGTL system, relative usage of interruptible service, level of utilization of designpipeline capacity.

Data is reported either by Pipeline Segment (25 segments make up the system) or Design Area (13 DesignAreas for the system). Maps of both are included in the reference section.

Firm Transportation Service Contract Utilization

The Firm Transportation Service Contract Utilization report shows the percent utilization for each of the 25NGTL pipeline segments and 3 major export delivery points comprising the total system. The utilizationdata is based on billed monthly volumes. Percent utilization is calculated as firm transportation service andfirm transportation service + interruptible service divided by applicable receipt or delivery contract level.Historical Data involving billed volumes lags the current date by approximately two months.

Design Capability Utilization

The load factor/segment flow graphs show actual flow versus design capability values for various NGTLsystem areas. The graphs also show seasonal (winter/summer) design capability and average load factors(LF) for each season. Load factors are obtained by comparing the receipt, delivery, or throughput flowcondition in each of the Alberta design areas against the corresponding design capability. Consequently,design capability utilization is measured as Average Actual Flow / Seasonal Design Capability. Data usedin these reports lags the current date by at least one month.

Design Flow Capability utilization is a function of several factors that include:

Total market demand for Alberta natural gas. Seasonal changes in market demand for Alberta natural gas. Receipt nominating practices of customers individually and in aggregate to meet that level of demand. Scheduled maintenance which could effect actual flow requirement in a design area at any given time. Design assumptions used in determining required segment flow requirement.

Future Firm Transportation Service Availability

The Future Firm Transportation Service Availability report presents guidelines and timing for all futurefirm transportation service requests.

Design Capability Utilization Actual Flow The amount of gas flowing within or out of the design area. Design Capability The volume of gas that can be transported from the design area on the pipeline system considering given design assumptions.

AVGLF (Average Load Factor) The ratio between average Actual Flow and Design Capability. It is calculated for every design season (summer/winter) as shown on the graphs.

Intra NGTL System Deliveries The amount of sales gas flowing off the system within an area. Receipt Flow Aggregate of actual receipts within an area and the Actual Flow of the upstream area.

Other System Load Factor The volume weighted average of the Average Load Factor (AVGLF) of all design areas on the system
