Trends influenced by internal factors:

• Consistent increase / decrease in demand

• Increased variation in the change of demand

• Flattening of demand profiles

• Increasing / reducing diversity

• Demand at satellite and source substations

• Increasing / reducing power factor

• Changes in seasonal demand variations

• Increasing influence of generation

Trends influenced by external factors:

• Demand and economic growth/downturn

• Demand and geographic location

• Demand and temperature or weather conditions

• Demand and geographic location

• Demand and customer type (domestic, industrial, commercial)

The nature of this research based study means that scope is likely to be altered, although probably in a relatively subtle manner, as the study proceeds. Any such changes will be agreed with the Northern Powergrid contact at the regular review & feedback meetings.
