Edmij

The operator of a 5 MW wind farm was selling its production on the day-ahead, intraday and imbalance markets. Balancing capacity was the one revenue stream left on the table.

Qualifying for aFRR was the blocker. TenneT requires a four-second control loop: measurements out of the asset and setpoints back in, every four seconds, without interruption.

Edmij connected the wind farm through the Teleport, which handles the four-second data exchange in both directions. That link runs into Edmij’s own trading and control system, so the asset meets the grid operator requirements.

A Dutch farm runs a 650 kWp solar installation alongside a 1.2 MWh battery. Its grid operator asked the farm to participate in congestion management, receiving payments to reduce export at peak moments.

The problem was the instrument. The grid operator’s requirement is about what leaves the site: export to the grid has to go be lowered. Without control at the connection point, the only way to guarantee that is to shut the inverters down, which leaves money on the table.

Edmij connected the site through Teleport and steers on the main connection instead of on the inverters. During a congestion event, export is brought to zero while the solar keeps producing. Everything generated goes to on-site consumption first, and the surplus charges the battery.
