112 WINES&VINES January 2016 CONSTRUCTION Because solar panels don't gen- erate electricity at night, compa- nies and researchers are investi- gating on-site storage of energy collected during the day. Jackson Family Wines was the first winery to work with Tesla Energy to pilot onsite stationary energy storage. During the past few years, Jackson has installed 21 battery systems at six of its wineries including Kendall-Jack- son, La Crema, Stonestreet and Carmel Road. These panels also draw elec- tricity from the grid during times of low demand and store it for later use and to smooth out energy spikes in two ways: Julien Gervreau of Jackson said, "These systems have the ca- pacity to store a combined 4.2 Mw (megawatts)/8.4 MWh (mega- watt hours) of energy, which will allow the company to mitigate the costly demand spikes that occur during the most energy-intensive practices in wine production: re- frigeration and cooling, com- pressed air, lighting and process water treatment. He expects that the Tesla bat- teries will reduce electricity costs across the pilot wineries by nearly 10%. This will help the company save hundreds of thousands of dollars annually and achieve its sustainability goals. The systems shift loads, reduc- ing electricity usage costs by shift- ing the times at which electricity is pulled from the grid (i.e., charging the battery at night, when electric- ity is cheap and the grid is stable, and using that energy during the day, when electricity is more ex- pensive and the grid is stressed). They also reduce peak demand spikes and charges by using elec- tricity stored in the batteries to smooth electrical load during times of high demand. A solar and storage project at UC Davis In 2016, the University of Califor- nia, Davis, will install 100 kW of new, highly efficient solar panels on the Jackson Sustainable Win- ery Building, said Jill D. Brigham, director of the Sustainable Wine and Food Processing Center. "High concentration of renew- able energy sources can destabilize the power grid due to their tran- sient nature (solar: sunrise/sun- set/clouds; wind: speed varies). This results in reversal of the flow of electricity in the systems making up the power infrastructure of the community/region/country that weren't designed for this. The power companies are struggling with this issue, and therefore the California Energy Commission is providing grant money to develop Providing leading wine makers with stainless steel barrels of high quality, durability, and design. phone: 773.735.0700 • toll free: 800.441.8780 www.skolnikwine.com • email: sales@skolnik.com www.scottlab.com • info@scottlab.com High-tech meets handcrafted.
