Detailed description		A forecast of wind and solar power net generation (MW) per bidding zone, per each market time unit of the following day. Current forecast: The information published is the last update of the current forecast. The information shall be regularly updated and published during intra-day trading; Day ahead forecast at 18.00: The information shall be published no later than 18.00 Brussels time, one day before actual delivery takes place.

The information shall be provided for all bidding zones only in Member States with more than 1 % feed-in of wind or solar power generation per year or for bidding zones with more than 5% feed-in of wind or solar power generation per year. Forecasts of wind and solar power net generation (MW) per bidding zone, per each market time unit of the following day: Current forecast Day ahead forecast at 18.00 Intraday forecast at 8.00 Detailed description of this information that will be published independently: Current forecast: The information published is the last update of the forecast.

The information shall be provided for all bidding zones only in Member States with more than 1 % feed-in of wind or solar power generation per year or for bidding zones with more than 5% feed-in of wind or solar power generation per year. Note: every submission has to be published at least as “current forecast”. For example, the last forecast submitted before 18.00 in D-1 will be published as “day ahead forecast at 18.00” but also as “current forecast”.
