Which locations can I value?

Any power location in your subscription. Locations whose day-ahead history EOX loads also get hourly shaping, backtests and realized basis; the result says which applied.

Can I see basis against a hub?

Yes. Compare a location with its hub month by month, on forward marks and on day-ahead settlements, in the browser, Python or REST.

Can basis positions go in a book?

Yes. The Portfolio page marks them with the rest of the book and includes them in value at risk.

Is this a valuation opinion?

No. It is the deal's value on EOX forward curves for your own analysis.

Basis valuation at nodal and zonal power locations

Value power deals at the nodal and zonal locations EOX publishes curves for, across the major US power markets, and see how each location's forwards have compared with its own day-ahead settlements.

What goes in, what comes out

The deal

The location, as named in your power curves, and the term
A fixed-price swap, a PPA or a battery, with its usual inputs
On-peak, off-peak or around-the-clock, and buy or sell
Or a book of basis positions on the Portfolio page, marked contract by contract

The results

Value month by month on the location's own forward curve
Hourly shaping and day-ahead backtests where EOX loads that location's day-ahead history
The location against its hub: forward basis and realized day-ahead basis, month by month
Mark-to-market and value at risk for basis positions alongside the rest of the book

Locations with day-ahead history include trading hubs, load zones, interfaces and individual nodes in each market EOX covers. Every entitlement applies as it does to the curves themselves.

Example

A 25 MW on-peak swap at NODE1, 12 months, and the same location against HUB1 over the past year:

Swap value−148,000at a 42.00 fixed price

Forward basis−3.10NODE1 minus HUB1, on-peak

Realized basis−4.25day-ahead, last 12 months

Months settled below mark8 of 12on-peak basis

NODE1 and HUB1 are placeholders and values are illustrative.

Use it from

Python

from eoxlive import EOX
eox = EOX("YOUR_KEY")
res = eox.value_deals([{"type": "swap", "iso": "ISO1", "market": "NODE1", "block": "on", "quantity": 25,
                        "price": 42.00, "start": "2027-01", "end": "2027-12"}])
res["deals"][0]["total"]

REST

curl -H "X-API-Key: YOUR_KEY" \
  "https://api.eoxlive.com/v1/analytics/forward-vs-realized?iso=ISO1&market=NODE1&basis_to=HUB1&months=12"
