Get the public ERE figures
Joulo's ERE figures. indicative is the one price for ERE that are not sold yet, per ERE and per kWh: the dashboard forecast, /ere-position and every estimate use it. customer_average and sales are history: what Joulo's past sales realised, never a forecast. The sales log holds month, price per ERE, volume and quarters. The same numbers as joulo.nl/ere-verkopen. Any personal token may read it; no scope needed. For your own money, use /ere-position.
