14-day price forecasts, half-hourly. Physics-first. Production-grade.

CEGridSight covers Great Britain and all of Europe — real-time and forecast electricity prices, generation mix, carbon intensity, and animated cross-border flows. Price forecasts run out to 14 days at half-hourly resolution from a pan-European MILP unit-commitment model across 43 zones (17 GB + 26 EU), solved with HiGHS: a causal chain from weather to demand to wind and solar to unit-commitment dispatch to carbon to price, with segmented heat-rate bids and full storage and interconnector physics. The full solve runs four times a day, a 30-minute intraday nowcast tracks the real-time market in between, and a bounded post-solve shape calibration is graded against the settled Elexon MID index.

CEGridSight — GB generation, price and carbon forecasts, 14-day horizon

Accuracy you can audit

Every forecast vintage is persisted and graded against the settled market — not a cherry-picked window.

Every vintage kept

Each forecast is persisted as issued, then scored when the market settles

Graded vs Elexon MID

Day-ahead forecasts scored against the settled GB day-ahead index

RT nowcast graded

The 30-minute intraday track is graded against the NESO/Elexon imbalance price

Explore-tier dashboards

Accuracy dashboards are in-product on the Explore tier — no paywall on the scorecard

We publish process, not superlatives: every vintage is stored and graded against the settled market as new settlements land, and a public track-record page is coming. Live track record.

How it works

Physics + calibration + serve.

Step 1

The causal chain

Every forecast starts from physics, not a price time series: weather → demand → wind & solar → unit-commitment dispatch → carbon → price. Each link is a model you can inspect, so when the price moves you can trace it back to the wind lull or the demand ramp that caused it.

Step 2

Pan-European MILP unit commitment

A coupled mixed-integer unit-commitment dispatch across 43 zones — GB resolved into the 17 NESO ETYS zones, plus 26 European bidding zones — with segmented heat-rate bids, storage physics, and cross-border interconnector NTC links at half-hourly resolution. GB is solved in two stages — a national clear, then a second stage over the 17 zones — so intra-GB constraints are respected, not averaged away. A representative production solve runs ~2M variables / ~1M constraints through HiGHS; the migration target is our native CEMeridian solver. The full 14-day solve runs four times a day (00 / 06 / 12 / 18 UTC), and a 30-minute intraday nowcast tracks the real-time market between solves.

Step 3

Calibrate, grade, serve

A bounded post-solve shape calibration sits on top of the physics and is graded against the settled Elexon MID index; the real-time nowcast is graded against the NESO/Elexon imbalance price. Forecasts land in a cached API with tier-gated horizon, stamped with the solve completion timestamp so clients can see freshness at a glance — and every vintage is persisted for grading.

European coverage

43 zones live — 17 GB + 26 EU.

GB resolved into the 17 NESO ETYS zones, plus 26 European bidding zones — Iberia, Nordics, Baltics, Central and Eastern Europe — all covered by the live forecast stack.

CEGridSight — European market view with animated cross-border dispatch map

Generator-level detail

Every generator in Europe, dispatch and revenue, 14 days out.

Because the forecast is a full dispatch — not just a price curve — you can open any individual generator across Europe and see its modelled half-hourly dispatch and estimated revenue for the full 14-day horizon. Download the lot as a table for your own analysis.

Training equals production: why we never train on synthetic hindcasts.

Why calibration is fitted and graded only on forecasts the model actually served, scored against the settled market — never on synthetic hindcasts.
