A live map of the European power system, and the Rebase Grid API: an open REST API for electricity market time series (day-ahead prices, load, generation by type, wind and solar forecasts, cross-border flows, balancing, grid frequency) from ENTSO-E, TSOs and exchanges. No API key is needed: every endpoint answers without one at 30 requests per minute; a free key gives 240.
