The voltages listed are nominal only. A. The equipment connected to the 12.47kV bus shall be at least 15kV class equipment, typical voltage range is from 0V to 13.8kV. 2. These values are minimum total output power for the Energy Storage Systems (ESS) at each site. Dmax of 4 MW is the minimum output for duration of 4 hours. This system should a modular system made up of smaller units (say 500kW or 1 MW) in parallel to give the total of 4 MW. 3. Huron is on the west side of South Lassen Ave (Hwy 269) on West Gale Ave.
