GB Generation — FUELHH Outturn & INDGEN Schedule

Temporarily unavailable

Scope note: FUELHH reports domestic generation outturn by fuel type. INDGEN reports scheduled exporting BM-unit Physical Notifications. Their difference is not a measure of forecast accuracy, demand variance or system imbalance.

Net Imbalance Volume (NIV) shows whether the GB electricity system is long (surplus) or short (deficit) in each settlement period. A persistently short system tends to push system buy prices higher; a long system tends to depress them.

System prices reflect the cost of balancing electricity supply and demand in each settlement period. They can be volatile and should not be interpreted as equivalent to wholesale forward-market prices.

EPI Intelligence

Data shows what is happening.
Intelligence explains what it means.

Public system data can show changes in wind output, electricity demand, system prices, gas flows and storage. EPI's subscription intelligence goes further — assessing how those developments interact with wholesale market pricing, forward-curve value, procurement risk and commercial decision-making.
