Energy Storage & Collection Engineering

ECI’s Battery Energy Storage System (BESS) experience includes nearly every conceivable scenario from the utility interconnection through design of the plant to the inverter and battery enclosure. This includes batteries installed in containers, modules or in buildings. BESS projects require close coordination with the battery supplier to manage their often proprietary and unique battery management system, energy management system, power conversion system (inverter) and communications / SCADA requirements. ECI has coordinated our designs with the industry’s top battery and inverter suppliers including Samsung, Tesla, BYD, XtremePower, CATL, Sumitomo, SMA, Powin Energy, Power Electronics, TMEIC, Energport and General Electric among others. ECI offers a complete solution for BESS projects including engineering analysis & studies, engineering specifications, site civil and foundation design, physical and electrical design, SCADA integration, owner engineer services, procurement & construction, and testing & commissioning.

ECI’s Collection Engineering Team has completed the design of hundreds of projects for wind, solar and BESS facilities, including singular projects from 10 MW up to 1100 MW. Design activities include preparation of complete drawing sets and corresponding studies. Typical studies conducted by ECI for collector design include cable ampacity & losses, grounding, short circuit, grounding bank & arrester evaluation, arc flash, reactive compensation sizing, and steady state load flows. ECI’s design covers all aspects of the collector system including system connectivity and mapping, power and fiber optic schematics, all pertinent installation details such as trench layout drawings, grounding plans & details, entrance & termination details, and meteorological tower and FAA obstruction lightning details where applicable.
