Envision Energy has launched its latest utility storage platform that features three 10 ft containers
It is equipped with 750 Ah battery cells and is capable of storing/delivering up to 12 MWh of energy
The lighter, modular nature of the storage system offers flexibility in transport and installation, reducing turnaround time and project costs
Battery energy storage solutions provider Envision Energy recently rolled out its upgraded Gen 8 Scalable Platform, designed for utility applications.
According to the company, this latest ‘Gen 8’ product combines the modular skid-based design of Generation 6 with the 750 Ah+ battery cell-based containerized design of Generation 7. The company says that the Gen 8’s 10 ft container or DC cubicle, with a storage capacity of up to 4 MWh, provides ‘high-energy density’ in a footprint that is 26% smaller than its predecessor. It also reduces the power consumption of auxiliary loads by 12%.
The product, consisting of 3 DC cubicles each mounted on a skid-based platform, can store/discharge up to 12 MWh of energy for more than 4 hours at a nominal charge/discharge rate. The company claims that these attributes, together, translate into an internal rate of return (IRR) uplift of 1% for a 100 MW/4-hour storage project compared to a baseline of 5 MWh.
In addition to the 12 MWh model, this modular design supports storage capacities of 6 MWh, 8 MWh, and 10 MWh. Envision added that it can also go beyond 12 MWh.
With each DC unit weighing up to 29 tons, the company says this ‘logistic-friendly’ lighter design provides flexibility in transportation, installation, and operation. It supports installation with lower-capacity (tonnage) transport vehicles or cranes, helping them operate in tight spaces while reducing overall project costs by improving the accessibility of different equipment to project sites. On the other hand, a higher-tonnage crane with a longer boom can also be employed to install multiple storage units, shortening the turnaround time by up to 30% with no on-site relocations needed.
In terms of safety, the storage system features a ‘multi-layer’ fire protection, covering the battery cell to the system level. Additionally, attributes such as dynamic balancing of cell-to-cell state of charge (SoC) support system operation at maximum usable capacity.
The commercialization details of this storage platform were not available at the time of publishing this article.
