ACER's 45th REMIT Quarterly puts algorithmic trading back in focus

ACER published its 45th REMIT Quarterly, covering Q2 2026. Algorithmic trading in energy markets features again as a lead topic under the REMIT surveillance framework. The repeated focus suggests the agency views automated order flow as an ongoing integrity risk across European wholesale markets.

Separately, Germany's Bundesnetzagentur opened a public consultation on the standardised rate of return on capital applicable to gas network operators. The outcome will feed directly into the next regulatory period's allowed revenues for German gas grids, with implications for infrastructure financing costs across the zone.

Both publications land at a moment when European energy regulators are tightening oversight on two fronts: trading conduct in power and gas spot markets, and the financial parameters governing network investment. Per ACER and Bundesnetzagentur, no final decisions have been announced on either file.
