What this means for electricity
Gas-fired stations are often the last plants needed to meet demand, so wholesale electricity prices frequently follow the cost of gas. The GB number here is National Gas SAP, not a separate NBP contract series. Henry Hub is the US benchmark from EIA. World Bank monthly Europe gas and Japan LNG are the Asian and European context Grid republishes. See today's electricity mix and the price cap explainer.

Questions
- What is the System Average Price?
- SAP is National Gas's published System Average Price for the GB gas day (PUBOB603), in p/kWh. The latest SAP Grid holds is 7.51p/kWh (220.1 p/therm) for 22 Oct 2026. Source: National Gas.
- What's the difference between SAP and NBP?
- NBP is the GB wholesale gas hub used in traded contracts. SAP is the published system average for the gas day. Grid republishes SAP from National Gas and does not republish a separate NBP series.
- How do p/therm and p/kWh convert?
- 1 therm is 29.3071 kWh, so p/therm = p/kWh × 29.3071. Grid stores SAP in p/kWh and shows p/therm for traders.
- Why does gas set the electricity price?
- Gas-fired stations are often the last plants needed to meet demand, so the wholesale electricity price frequently follows the cost of gas. See today's mix on /today. Grid does not claim a share of hours without a cited calculation.
