Netherlands EPEX Day-Ahead Price API

You need a reliable way to fetch the latest Netherlands EPEX Day-Ahead power price and drop it straight into your finance stack. By the end of this guide, you’ll call the Energy API, read the EUR/MWh quote for the Netherlands EPEX Day-Ahead symbol, and integrate the fields you actually need into pricing, P&L, or risk workflows.

What the Netherlands EPEX Day-Ahead quote represents

The Netherlands EPEX Day-Ahead price is a day-ahead wholesale electricity benchmark for the Dutch market. In the Energy API catalog it is:

• Symbol name: Netherlands EPEX Day-Ahead
• Symbol code: EPEX_NL_DA
• Unit: EUR/MWh

This guide focuses on programmatically retrieving the latest published value and the effective date fields you’ll reference in finance applications such as scenario analyses, marked-to-market updates, or settlement estimates.

Endpoint and authentication

The latest quote is returned by a single GET request:

• Method: GET
• URL: https://energy-api.com/api/v1/latest
• Required query parameters:
  • symbols: EPEX_NL_DA
  • api_key: YOUR_API_KEY

Authentication uses an api_key query parameter only. There is no separate host to configure and no MCP layer to traverse.

Pricing and trial

The Starter plan is $19.99/mo. A trial is available for 7 days with 50 calls. If you plan to run scheduled jobs, budget your call cadence accordingly and cache results to minimize duplicate requests within the same trading day or auction cycle.

Quickstart: cURL request

Copy, paste, and run this exact cURL command to retrieve the latest Netherlands EPEX Day-Ahead price:

curl -G "https://energy-api.com/api/v1/latest" --data-urlencode "symbols=EPEX_NL_DA" --data-urlencode "api_key=YOUR_API_KEY"

Replace YOUR_API_KEY with your own key. The response contains the price in EUR/MWh, along with date metadata.

Official JSON responses and what to read

Netherlands EPEX Day-Ahead — real payload

The following is a real response for the Netherlands EPEX Day-Ahead symbol. Use it as your reference for payload structure and field names:

{"success":true,"date":"2026-11-02","base":"EUR","rates":{"EPEX_NL_DA":251.2593},"dates":{"EPEX_NL_DA":"2026-11-02"},"currencies":{"EPEX_NL_DA":"EUR"},"base_filter_note":null,"missing_symbols":null}

Key fields you will typically read:

• rates.EPEX_NL_DA: The latest day-ahead price value in EUR/MWh.
• dates.EPEX_NL_DA: The effective date of the symbol’s latest price.
• currencies.EPEX_NL_DA: Currency code for the symbol (EUR).
• date: The API’s response date for the batch (may be useful for reconciliations).
• base: Response denomination context. For mixed requests, this may be MIXED; for this single-symbol example it is EUR.

Official sample format — comparative reference

This official sample illustrates the exact JSON structure the endpoint returns (note: this block shows a different market symbol but the structure is identical):

{
"success": true,
"date": "2026-11-02",
"base": "EUR",
"rates": {
"OMIE_ES_DA": 177.0622
},
"dates": {
"OMIE_ES_DA": "2026-11-02"
},
"currencies": {
"OMIE_ES_DA": "EUR"
},
"base_filter_note": null,
"missing_symbols": null
}

Interpretation is the same: use the symbol within rates, dates, and currencies to read the value, effective date, and currency, respectively.

Netherlands EPEX Day-Ahead — structure-focused example

Here is the Netherlands EPEX Day-Ahead response again for ease of copy-testing field extraction during development:

{"success":true,"date":"2026-11-02","base":"EUR","rates":{"EPEX_NL_DA":251.2593},"dates":{"EPEX_NL_DA":"2026-11-02"},"currencies":{"EPEX_NL_DA":"EUR"},"base_filter_note":null,"missing_symbols":null}

Most finance workflows will map rates.EPEX_NL_DA to a numeric price field (double/decimal), dates.EPEX_NL_DA to a date column (ISO-8601 string), and currencies.EPEX_NL_DA to a 3-letter currency string.

Python example: fetching and parsing EPEX_NL_DA

This Python snippet fetches the latest Netherlands EPEX Day-Ahead price, parses the expected fields, and prints them in a finance-friendly format. It is intentionally minimal and avoids dependencies beyond the standard library and requests.

import requests
import datetime

API_URL = "https://energy-api.com/api/v1/latest"
API_KEY = "YOUR_API_KEY"
SYMBOL = "EPEX_NL_DA"

def fetch_latest(symbol: str):
params = {
"symbols": symbol,
"api_key": API_KEY
}
r = requests.get(API_URL, params=params, timeout=10)
r.raise_for_status()
data = r.json()
return data

def parse_quote(data: dict, symbol: str):
# Required fields for finance integration
price = data["rates"][symbol]
effective_date = data["dates"][symbol] # e.g., "2026-11-02"
currency = data["currencies"][symbol] # "EUR"
batch_date = data.get("date") # API response date string
base = data.get("base") # "EUR" or "MIXED" in multi-symbol queries

# Normalize to a structure you can load into a price table
return {
"symbol": symbol,
"price": float(price),
"unit": "EUR/MWh",
"effective_date": effective_date,
"currency": currency,
"api_batch_date": batch_date,
"base": base
}

if __name__ == "__main__":
result = fetch_latest(SYMBOL)
quote = parse_quote(result, SYMBOL)
print(quote)

Notes:

• rates, dates, and currencies are keyed by the symbol code (EPEX_NL_DA). Always look up by the symbol you requested.
• Store effective_date separately from the API’s batch date for transparent auditing.
• If you later expand to multi-symbol queries (e.g., additional day-ahead regions), the base field may be MIXED depending on the portfolio—handle this by relying on currencies.SYMBOL for currency mapping.

Field semantics, units, and dates

For the Netherlands EPEX Day-Ahead quote:

• Unit: EUR/MWh (quantitative field rates.EPEX_NL_DA is in this unit).
• Currency: EUR (currencies.EPEX_NL_DA returns EUR).
• Effective date: dates.EPEX_NL_DA is the official date of the price.
• Response date: date is the API’s batch date for the response payload.

Day-ahead markets typically publish one value per delivery day. If your job runs multiple times per day, expect the same date/value pair until the next auction cycle is reflected. Implement idempotent upserts keyed by (symbol, effective_date) to avoid duplicates in your price store.

Production considerations for finance workflows

• Job scheduling: Run after the market’s day-ahead publication window. Cache the payload for the rest of the day to conserve calls.
• Idempotency: Use dates.EPEX_NL_DA as a stable primary key component alongside the symbol.
• Type safety: Persist price as a decimal with sufficient precision (e.g., 6–8 decimal places) to avoid rounding errors when converting to costs across MWh volumes.
• Currency handling: Use currencies.EPEX_NL_DA rather than the top-level base when normalizing multi-symbol batches. For this single-symbol endpoint call, base may be EUR; for mixed requests it may be MIXED.
• Error handling: Check success is true before using fields. If an optional field is null, handle gracefully.
• Retries: Use short exponential backoff on transient network errors; log the request ID (if provided in headers) together with date and symbol for traceability.
• Non-trading/holiday context: Day-ahead power markets still provide daily values; if a date appears unchanged, prefer cached data until a new effective date is visible in dates.EPEX_NL_DA.

Energy API usage rules that matter here

• Symbols: Use EPEX_NL_DA for Netherlands EPEX Day-Ahead.
• Authentication: Pass your api_key as a query parameter (api_key=YOUR_API_KEY).
• Base parameter: Do not add base=USD when you also need TTF_GAS or EUA_CO2 (those can be MIXED). For this single EPEX_NL_DA call, you don’t need to set a base at all.
• Host: No MCP host is required—use the URL shown above.
• Plan: Starter $19.99/mo, with a 7-day trial and 50 calls.

End-to-end validation checklist

• Request returns HTTP 200 and success is true.
• rates.EPEX_NL_DA is present, numeric, and greater than zero.
• dates.EPEX_NL_DA is an ISO-8601 date string you can parse server-side.
• currencies.EPEX_NL_DA equals EUR.
• Data is upserted using (symbol, effective_date) as a uniqueness key to avoid duplicates.
• Job execution logs include timestamp, symbol, effective_date, and price for reconciliation.

Troubleshooting common issues

• Missing or invalid api_key: The request must include api_key=YOUR_API_KEY in the query string. Verify your key and environment variables.
• Unexpected base value: For multi-symbol calls, base may be MIXED; use currencies.SYMBOL per-instrument for currency-safe transforms.
• Stale data on intraday reruns: If the effective date hasn’t changed, you are still seeing the current day’s quote. Cache the result and recheck after the next publication time.
• Overusing trial calls: The trial provides 50 calls across 7 days. Batch related symbols and cache within the same day to stay within limits.

FAQ

What symbol should I pass for the Netherlands EPEX Day-Ahead price?
EPEX_NL_DA. Read the numeric value in rates.EPEX_NL_DA, the effective date in dates.EPEX_NL_DA, and the currency in currencies.EPEX_NL_DA.

What unit is the price expressed in?
EUR/MWh. The currency field also returns EUR for this symbol.

How do I authenticate?
Include your key as a query parameter: api_key=YOUR_API_KEY. No headers are required for auth.

Should I pass a base currency?
Not required for single-symbol calls. Do not pass base=USD when you also need TTF_GAS or EUA_CO2 because the base can be MIXED across those instruments.

What are the plan and trial terms?
The Starter plan is $19.99/month, and the trial gives you 7 days with 50 calls.
