Industrial storage, intelligently deployed - beyond self-consumption

C&I stands for Commercial and Industrial storage solutions — battery systems typically ranging from about 250 kW to 5 MW, often installed directly on company sites. They help businesses reduce electricity costs, maximize self consumption, increase autonomy, and lower grid fees. A distinction is generally made between behind the meter (BTM) and front of the meter (FTM): while BTM storage is primarily used for internal consumption, FTM storage is directly connected to the grid and can participate in the energy market. Things become especially interesting when companies leverage their storage systems for energy trading — either in combination with self consumption or as a stand alone unit.

• Peak shaving
  Cut peak loads and reduce grid fees — especially relevant for sites with high connection capacity or demand charge structures.
• Self consumption optimization
  Store PV surpluses and use them during expensive periods — lowering external electricity procurement costs.
• Energy market participation (FTM)
  Storage can trade on day ahead, intraday, and ancillary service markets. While the technical minimum size for bids in ancillary services (e.g., FCR, aFRR) is 1 MW, in practice participation in energy and capacity markets becomes economically attractive only from about 3 MW.
• Combining both applications
  With a split storage architecture, companies can benefit from both self consumption and flexibility trading simultaneously.
