Coral app · Nomination Bridge

From executed trade to accepted nomination. Automatically.

Nomination Bridge runs inside Previse Coral and turns day-ahead and intraday power trades from EPEX SPOT into netted, scheduled nominations in GMSL PowerTrak, submitted to the market operator and confirmed back. No one touches a spreadsheet.

01 — How it works

One straight line from the exchange to the grid operator

Every run reads the live position from Coral, condenses it into a clean schedule, and files it where the market operator expects it.

01
EPEX SPOT
Day-ahead and intraday power trades, imported into Coral as they are executed on the exchange.
Day-ahead & intradayTrade import
02
Previse Coral
Trades land as contracts; a pre-configured report delivers the position per delivery period.
ContractsPosition report
03
Netting engine
Gaps filled to a complete half-hour grid, buys netted against sells, so only one direction remains per period.

GMSL PowerTrak
The nomination is built and submitted to the scheduling platform, tracked by its correlation ID.

05
Market operator
PowerTrak forwards the schedule to the grid operator; the app polls until acceptance is confirmed.

02 — Netting, visualised

48 periods in, one schedule out

Try the switches: the 15-minute view is where European intraday markets are heading, and the clock-change day shows a schedule that follows the real length of the delivery day.

03 — What it handles

What the app takes care of

The whole path from position to accepted schedule. Each step is a job someone no longer has to do by hand.

Aggregation
Position, not trade noise
Reads the aggregated buy and sell position per delivery period straight from a Coral report.
Gap filling
Always a complete day
Periods without trades are filled in, so the schedule always covers the full delivery day.
Netting
One direction per period
Buys are netted against sells; only the remaining volume is nominated.
Submission
Straight into PowerTrak
Builds the nomination and files it with GMSL PowerTrak toward the market operator.
Confirmation
Trust, then verify
Tracks every submission by its correlation ID and polls until the nomination is accepted.
Scheduling
Runs itself
Triggered by Coral's internal scheduler, day and night. No one has to press a button.
04 — Built into Coral

No extra system to run

01

Lives where your trades live

The app runs inside Previse Coral itself: same platform, same data, same operations team. There is no separate server, no second login, no interface to keep in sync.

05 — Extensions

Built for where the market is going

France settled imbalances on 15 minutes from January 2025, and Europe's coupled markets moved to 15-minute trading periods later that year. The app is designed for that direction of travel.

01
15-minute grids
Quarter-hourly nominations with 96 periods a day for markets that settle on 15 minutes, and hourly grids for those that don't.
02
Clock-change days
Correct handling of the 46- and 50-period days that daylight saving time creates.
03
More markets
Additional market operators, TSOs and balance areas served from the same app.
04
Renomination
Re-submit as the intraday position changes, right up to the market's deadlines.
05
Monitoring & alerting
Notify the desk the moment a nomination is rejected or overdue.
06
Audit trail
A complete record of every schedule ever submitted, and what the operator answered.
