Partial

Description

This service allows for a reduction in gas demand on a site, rather than full interruption. The amount of reduction is agreed in a series of 'Tranches' in order to arrive at a gas supply profile which best serves the individual needs of the site.

Sites suitable for this service

The following conditions would need to be satisfied to enable a site to be accepted as a partial interruptible customer:-

  • The meter or meters making up the interruptible supply point must use more than
    11,722,840 kWh (400,000 therms) per annum to gain any benefit from this service.
  • Minimum tranche quantity is 200,000 therms, maximum number of tranches allowed is nine.
  • The site must have equipment for daily metering and may require telemetry. Siteworks charges would be incurred for any upgrading of monitoring equipment.
  • The site must be able to cope during periods of interruption, at which time the interruptible gas load will not be allowed to flow.
  • Interruption can be called for on a tranche by tranche basis - the gas burning equipment on site must be bale to cope with these tranche call offs.
  • All tranches could be interrupted at one time.

Benefits

  • May allow gas consumers to balance their requirement and enjoy greater protection from the risk of full interruption, thus maintaining critical processes.
  • May enable a proportion of the site load to burn during an interruption period, without incurring a failure to interrupt charge.

Allows the gas consumer to exercise a choice in which plant to operate to achieve the offtake rate reduction requested.
