Billing and Metering
In EirGrid, Grid Revenue and Metering provides data feeds to SEMO on a daily basis. We are responsible, in our role as Transmission Meter Operator, for providing meter data for all transmission connected generating units. Since 1st November, this data is transmitted on a seven day basis. Dispatch instructions and availabilities are compared with the metered output before submitting to SEMO. In conjunction with this we conduct manual on-site checks on all polled meters every three months.
A key role for Grid Revenue and Metering is the invoicing and payments associated with a range of other transmission and market related services including:
- Transmission Use of System
- Services
- Capacity Margin*
- Winter Peak Demand Reduction Scheme
- Interruptible Load
- Interconnector nomination processes*
- Powersave
*Discontinued on the 1st November 2007
These services are essential to the operation of the market and power system. They cover the collection of charges for usage of the Transmission System and securing the provision of Ancillary Services, such as operating reserve. They also include providing incentives for capacity to be available through the Capacity Margin scheme and the promotion of overall efficiency via reductions in peak demands as part of the Winter Peak Demand Reduction Scheme. The Interruptible Load arrangements provide a key element of overall system security through contracting with large customers to automatically drop load in the event of significant dips in the frequency.
