BESS DESIGN AND INSTALLATION
Westphal & Company is a “full service” electrical contractor. We provide any and all electrical and technology construction services our clients require, from large industrial and institutional facilities to a residential service call.
The Peak Capacity Market determines the cost of electricity at different times of the day. When there is high peak demand – hot days, weather events – grid operators (MISO, PJM, ERCOT, etc.) charge more for transmitting power. Utility battery systems can react faster to market fluctuations than “spinning metal” (turbines) resources like coal or gas fired plants. Until now, solar generated energy needed to be used instantaneously. Now power can be stored and used for peak demand offset. This makes the grid more resilient by reducing stress on transmission. Investor-Owned Utilities are being asked to de-carbonize operations. Battery storage coupled with large solar installations are a path toward this goal. Utility battery storage is a growing trend nationwide.
Advantages of BESS for Solar Installations:
- Balancing electricity loads – assuring equal power supply on days where solar production is reduced due to environmental factors.
- Hardening the solar power generation – preventing quick changes from brief power disruptions.
- Reliability – Solar storage can be used for microgrids and keeping essential services like communications uninterrupted.
OUR EXPERIENCE
WOOD COUNTY BESS
Wood County BESS is a 96 battery, 300 MWh installation adjacent to the 150 MW Alliant Energy Wood County Solar Installation and a new substation to receive battery stored power. Stored electricity can support 80,000 residential homes for four hours. Electricity from the BESS is fed into the adjacent substation. Stored energy can then be used to alleviate or lessen sharp power demands in Alliant’s utility grid network. Wood and Grant County are the first large, utility-scale battery storage installations in Wisconsin. The electrical scope of Wood County covers 80% of the project.
BATTERY DETAILS
- 96 (CATL) (3 MWh) Lithium-ion batteries.
- Each battery weighs 80,000 pounds.
- Ambient temperatures require self-contained heating and cooling.
- Equipped with fire detection and fire suppression.
- Power export generates heat – integrated HVAC system cools/heats.
- Redundant power support from 2nd substation 6 miles away.
