GoEpexSpot

GoEpexSpot aims to be a comprehensive API client for fetching Day-ahead EPEX SPOT prices using Golang.

Currently, EPEX SPOT and Nord Pool does not offer a free (or easily accesible) API for non-commercial uses. However, some stakeholders do provide access. This repository aims to highlight such resources, starting with the French Transmission System Operator (RTE) API for real-time data access.

This repository facilitates price-driven demand response, thereby encouraging environmentally friendly behavior as prices frequently correlate with CO2 marginal emissions.

Description

GoEpexSpot is designed to unlock the potential of Day-ahead EPEX spot prices for electricity through a unique Go-based API client. In the absence of a freely accessible electricty price API from EPEX SPOT or NordPool for non-commercial purposes, this repository shines a spotlight on alternative sources, beginning with access via the French Transmission System Operator (RTE) API for timely data retrieval. By enabling a price-driven demand response, GoEpexSpot not only facilitates financially smarter energy consumption decisions but also promotes eco-friendly practices as energy price tend to be linked with CO2 emissions.
