What a site gains with a Suntech battery and our EMS
Our EMS optimises charging and discharging against day-ahead prices, shaves peaks and decides when to curtail at negative prices. The effect was measured in a study with real IBEX prices.

Results of a 2026 study by a TU Sofia team with Novacom's participation: a MILP model of a community of three industrial prosumers with Suntech SunStorage PRO equipment and twelve months of real day-ahead prices from IBEX (the Bulgarian power exchange). Values are simulated, for the specific sites in the study.
