Industry Services

IMServ has been involved in various stages of the industry’s evolution and service provision, established in 1992 as the sole Data Collector to the UK electricity market prior to the full deregulation of the industry. With current industry roles of Data Collection, Meter Operations and providing data collection for the Balancing & Settlement Code (BSC) Central Services.

BSC Central Service in Summary

Electricity is traded on a wholesale market, with generators and suppliers entering into contracts with each other for every half hour of every day; sometimes years in advance. Non-physical traders such as investment banks also participate in this trading. For each half an hour – known as a settlement period – they can continue to trade up to 1 hour beforehand. At this point the market for that time period is closed – this is known as Gate Closure.

Following Gate Closure, National Grid uses the balancing mechanism to balance the system. Contract notifications, bids and offers, and other data, are passed to BSC Central Services for imbalance settlement.

BSC Central Services ensure that all metered data is collected from generation sites such as power stations, this is in turn balanced against the metered data collected from Suppliers through their data collection processes. The BSC Central Services then calculate the trading charges for each market participant, making payments or issuing invoices where appropriate.
