Residual demand = demand − wind − solar. Left for GB flexible plant = residual demand − net imports + extra outage. Starts from the latest readings. Real outcomes also depend on storage, constraints, reserve and the system operator's actions, so this is a teaching aid, not a forecast.

Shipping context

How to read UK LNG activity

Britain’s three import terminals are Grain LNG on the Thames and Dragon LNG plus South Hook LNG at Milford Haven. A rise in terminal inflow can be consistent with unloading or inventory movements; rising send-out means more regasified LNG is entering the transmission system.

Stock risingPotential replenishment or lower send-out. Confirm against terminal flow and dates.
Send-out risingLNG is contributing more gas to the NTS, which may ease other supply requirements.
Stock fallingInventory is being drawn. The significance depends on demand, pipeline imports and storage.
Vessel caveatFree terminal data cannot confirm a ship’s identity, cargo origin, destination or arrival time.

UK energy learning

Learning

Understand the UK energy market through clear explanations, real historical data, and guided exercises.

Start here

Read the market in three steps

01

Check the timestamp

A figure is only useful when you know when it was observed. “Live” feeds can still publish late or revise a period.

02

Compare demand and supply

High demand, lower wind or reduced imports may leave more generation to be supplied by gas or flexible assets.

03

Inspect price and balance

System price is an imbalance price, not a household tariff or a day-ahead auction price. Check its settlement period and NIV.

Core UK energy terms

UK energy glossary

Search short definitions, then use the same terms when reviewing market data.

Settlement period

A numbered half-hour of the GB electricity market. The day usually has 48 periods; clock changes can alter that count.

System price

The cash-out price used to settle electricity imbalances for a period. It is not the same as a day-ahead wholesale price.

Net imbalance volume (NIV)

A measure of net balancing actions in a settlement period. Its magnitude helps show how much balancing occurred.

Day-ahead price

A price from an auction for delivery on the following day. This site does not yet publish a verified day-ahead price feed.

Balancing Mechanism

One of the tools the system operator uses to adjust generation or demand close to real time.

Long and short

In an illustrative market position, a long position benefits when the relevant price rises; a short position benefits when it falls. Real settlement depends on the actual market rules and contract.

MW

Megawatt measures a rate of power at a moment in time, such as the current level of demand or wind output.

MWh

Megawatt-hour measures a quantity of energy. One megawatt sustained for one hour produces one MWh.

Renewable share

The share of generation supplied by wind, solar and hydro in this dashboard. It is not a forecast of the next settlement period.

Residual demand

The electricity demand remaining after weather-driven generation such as wind and solar is accounted for.

Interconnector

A cable connecting GB with another market. Imports add supply to GB; exports send electricity out of GB.

Linepack

The gas held within the high-pressure transmission network. It offers short-term flexibility, not seasonal storage.

Short explanations

Why markets move

Why can the system price become negative?

When the system has excess supply and needs to reduce generation or increase demand, balancing actions can make the imbalance price negative. A negative price does not mean all electricity is free; it applies to a specific market settlement context.

Inspect system price and NIV →
What if wind generation misses its forecast?

If actual wind is below a forecast, other sources may need to fill the gap. The effect depends on demand, available gas generation, imports, storage, constraints and the time of day. A forecast miss is a clue, not a guaranteed price move.

Inspect wind forecast error →
What does a net power import tell us?

Net imports add electricity supply to GB, but the net figure can hide opposing flows on individual links. Compare the link-level outturn with demand, generation and prices on both sides of the border.

Inspect interconnector flows →
