BSUoS
Key takeaways
BSUoS is a charge that recovers the cost of balancing the electricity transmission system.
It relates to real-time system operation, keeping supply and demand in balance.
It may be bundled into your price or shown as a separate non-commodity line, depending on your contract.
What does BSUoS stand for?
BSUoS stands for Balancing Services Use of System.
NESO describes BSUoS as recovering the cost of day-to-day operation, including the cost of balancing the electricity transmission system.
Why does the charge exist?
Electricity systems must stay stable in real time.
If demand rises or generation drops unexpectedly, the system operator has to take actions to keep the system balanced and secure.
BSUoS is one of the ways those operational balancing costs are recovered through the industry and, ultimately, bills.
How does BSUoS show up for businesses?
It depends on your tariff structure:
All-inclusive
- included inside your unit rate
Pass-through
- may appear as a separate BSUoS line item, which can vary over time
