Does the shape change the block prices?

No. Each block's hours average back to the on- or off-peak price exactly; the shape only spreads the price across the hours.

Where does the shape come from?

The location's own day-ahead prices over the recent months you choose: each hour's typical level against its block's average, by month, day type and hour.

Which locations are covered?

Locations in your subscription whose day-ahead history EOX loads: trading hubs, load zones and many nodal locations.

No. It spreads forward block prices over the hours the way recent day-ahead prices have been spread, for your own models.

Hourly shapes from block prices

Turn a month's on- and off-peak prices into an hourly curve for models that need hours rather than blocks: shaped from the location's own recent day-ahead prices, with each block averaging back to its price exactly.

What goes in, what comes out

Your choices

The market and location, as named in your power curves
The month
EOX's own on- and off-peak marks for that month, or prices of your own
How much recent day-ahead history shapes it, one to 36 months

The results

A price for every hour of the month, in local time, with its block and day type
The average shape by hour for weekdays, Saturdays and Sundays or holidays
The highest and lowest hours, and the around-the-clock average
A check that each block averages back to the price given

On-peak hours follow the market's own definition and holidays, the same blocks the forward curves use. Days when clocks change have 23 or 25 hours.

Example

Hour ending	Weekday	Saturday	Sunday / holiday
6	31.40	29.85	28.10
12	44.75	39.20	36.55
18	71.30	58.65	54.90
22	49.10	44.35	42.80

Values are illustrative.

Use it from

Python

from eoxlive import EOX
eox = EOX("YOUR_KEY")
eox.shape("LOCATION1", "2027-07", on_price=72.50, off_price=31.25)   # every hour of the month, as a DataFrame

REST

curl -H "X-API-Key: YOUR_KEY" \

Or in the browser: Hourly shapes on the Valuation page, signed in with your EOX account, shapes EOX's own marks for any month and downloads every hour as CSV.
