Forecast inaccuracies by green aggregators between November 1 and February 14 cost the RES special account a total of 7.7 million euros, RES market operator DAPEEP’s head official Yiannis Giarentis has alleged in a letter to RAE (Regulatory Authority for Energy) chief executive Thanassis Dagoumas.

This cost arises as green aggregators are not charged for their discrepancies. Instead, amounts they return are limited to sums received through the market at day-ahead market price levels.

Green aggregators are not making any effort to improve their forecasts as, under the current rules, they do not shoulder the cost of discrepancies, the RES market operator head official explained in his letter.

On the contrary, existing balancing market regulations enable green aggregators to maximize profits at the cost of the RES special account, a situation that RAE must investigate, Giarentis pointed out.

The DAPEEP chief, in his letter, has called for an amendment to a related law, ratified in 2016.
