What power will cost — two weeks out, half hour by half hour.

CEGridSight forecasts electricity prices from the physics up: weather drives demand and renewables, a full model of the grid dispatches every power station, and the price falls out at the end — across 43 zones. Every forecast is saved before settlement and scored against the real market, in public.

CEGRIDSIGHT — GB DAY-AHEAD VS SETTLEDLIVE

What it does

A physical model of the market, not a regression on price history.

The causal chain

Weather → demand → wind & solar → dispatch → carbon → price. Because the model is physical, you can ask it why: which plants set the price, what congestion cost, what the wind did to the evening peak.

Graded in public

Every forecast vintage is persisted before the settlement period it covers, then graded against the settled market. The track record page needs no login and nothing on it is hand-picked.

Zonal depth

GB resolved into its 17 transmission zones — constraint costs and zonal prices, not a national average — with 26 European bidding zones coupled in the same solve.

For the quants

How the served price is made.

FormulationA mixed-integer unit-commitment model over 43 zones at half-hourly resolution: no-load costs, min up/down, ramps, reserve, inertia, storage cycling, cross-border NTC flows with directional losses.
Two-stage GB solveStage 1: a national wholesale market whose dual sets the served GB price. Stage 2: a 17-zone zonal redispatch producing constraint costs and zonal LMPs.
CalibrationA thin per-hour calibration fitted on a rolling window of (dual, settled index) pairs with walk-forward self-acceptance — bounded, audited, and suppressed when it fails its own gate.
Real-time trackA 30-minute intraday nowcast solving in ~0.2 s, anchored to the day-ahead curve and graded against the imbalance price by lead-time bucket.
Battery revenuePer-asset BESS capture computed downstream of the price solve — so it can never distort the forecast — in national and zonal bases.
SolverThe production wholesale LP is solved by our own CEMeridian engine with an enforced optimality certificate, with an open-source fallback always on standby.

Grading benchmark: GB day-ahead forecasts are graded per settlement period against Elexon’s settled traded index — a harder benchmark than the day-ahead auction — and the real-time track against the imbalance price.
