Co-located BESS at Dekker Group’s sand extraction site Bomhofsplas

Bomhofsplas needs one control layer that facilitates three jobs at once. The sand extraction facility needs as much local renewable energy as possible. Greenchoice needs to optimize PV and BESS across wholesale and balancing markets. The whole site must stay within grid capacity limits, including CBC capacity schedules from Enexis.

Trading setpoints need  to be prioritized and executed reliably, to ensure imbalance and non-delivery risk are minimized, to allow the asset owner to deliver on the business case.

At the Bomhofsplas, we act as EMS provider and system integrator via STELLAR, working closely together with Green Energy Storage and Tesla to:

• Integrate the co-located floating PV and Tesla BESS with the main meter
• Run the local Power Plant Control for the hybrid site
• Support multi-asset, multi-market control within grid capacity limits
• Enable stacked services across Day-Ahead, Intraday, Passive Balance, Frequency Containment Reserve (FCR), automated Frequency Restoration Reserve (aFRR), and CBC capacity schedules

We deliver the STELLAR control and integration layer that ties the site together and allows for commercial value generation.

Bomhofsplas runs as a multi-market co-located BESS site on STELLAR. The PV and battery operate under the same EMS and Power Plant Controller , within Enexis capacity limits and CBC schedules.
