Castello Di Amorosa Installs a Solar Microgrid

Calistoga, Napa Valley, January 2022 – Castello di Amorosa, Dario Sattui’s authentically-built 13th century castle and winery, has just invested $1.4 million in a 450-kilowatt solar and battery microgrid. The massive 1,232 panel solar system was completed in January of 2022 and is situated on a  slope that was significantly burned in the Glass Fire that hit the Napa Valley in 2020.

“This enormous investment is an important element of our commitment to become as self-sufficient as possible while minimizing our carbon footprint and helping with the climate change crisis. We expect this will offset our energy usage around 80%,” explains Georg Salzner, President, Castello di Amorosa.

Castello di Amorosa partnered with Centrica, Recolte Energy, and 127 Energy on the multiple components of this installation. 127 Energy designed the 556-kilowatt battery storage microgrid. Using advanced and remotely accessed power controls, the microgrid provides Castello di Amorosa with an independent power supply during frequent utility grid outages. During times of normal operations, the microgrid reduces utility energy charges and demand charges, resulting in significant operational savings for the winery.

“Due to fire risks and skyrocketing power prices, commercial business owners in California are taking matters into their own hands. Castello di Amorosa, Centrica Business Solutions, and Sungrow were great partners on this project and our collaboration exemplifies how innovative teams can solve daunting environmental and energy-related challenges,” said Mark Crowdis, CEO of 127 Energy. “The battery storage microgrid provides a striking juxtaposition of resilient, clean energy technology against the backdrop of historic castle grounds,” Crowdis added.

Other examples of Castello di Amorosa’s environmentally friendly programs and practices:

  • Napa Green Certified: the winery has been Napa Green Certified since May 2018 (renewed in June 2021). Being Napa Green Certified’s requirements include LED Lighting, using a minimum of 50% recycled paper in the winery offices; using recycled cardboard and recycled pulp for shipping (instead of Styrofoam), using green certified cleaning agents and hand soap; using recyclable/compostable plates/flatware.
  • Bio Microbics Micro Fiber filtration system: the winery treats all of its processed water (water used during production of wine) and re-uses it for landscaping. Since 2017, the winery has treated and re-used over 5,000,000 gallons of water.
  • The winery has begun composting as of January, 2022.
  • Napa Ride Share program: the winery pays employees to carpool, thus eliminating more cars on the road.

Castello di Amorosa owns and farms 130 acres in Napa, Sonoma and Anderson Valley.

The winery is one of Napa Valley’s most respected landmarks and welcomes visitors by appointment seven days a week: www.castellodiamorosa.com.

One of the main resistances to phasing out glyphosate is increased labor and equipment costs. However, the costs of herbicides and fertilizers have risen dramatically, so increased labor demands can be offset by reduced supply chain purchases. 

In addition, leaders like Grgich Hills Estate have shown that regenerative organic farming can be cost-effective. According to an analysis by Brotemarkle Davis & Co. LLP accounting firm, the average annual per acre cost of vineyard management in the Napa Valley is $14,800, with $3,800 in depreciation. At Grgich, they spend $11,000 per acre, with only $1,300 in depreciation due to the longer life of their vineyards. 

Learn from regional leaders about the practical costs, benefits, and ROI of herbicide-free, organic, and regenerative vineyard management.

Join us for a special roundtable workshop with award-winning journalist Elin McCoy, global wine critic for Bloomberg News and US editor for the podcast The Wine Conversation, with listeners in 95 countries. 

Elin will sit down with a small group of Napa Green members (max 25 guests) and share her insights on the types of stories and pitches most likely to engage the media. In particular, she’ll focus on stories related to sustainable winegrowing, climate action, and social equity. 

Elin will speak and answer questions for about an hour. Then we’ll break into small groups to develop a story pitch, and come back together to present and get Elin’s feedback and input. This is a rare opportunity to get ideas and inspiration from a leading wine journalist. Register at the link in our profile.

One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. 

Join us for The Future of Water, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts, and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Join us for The Future of Water Workshop, to explore our water future, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts (all guests will receive a copy of Peter’s most recent book, The Three Ages of Water) and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Wine grape quality is closely tied to the right amount of water, at the right time. One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. We’ve swung from historic drought to atmospheric rivers. Our community has huge swaths of unmanaged, unhealthy forests full of non-natives and overrun by firs, amplifying fire risk and undermining one of the most critical systems for groundwater recharge.

The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. A watershed coalition has also formed in Napa County to pilot and model creek & forest restoration for localized water resiliency and climate cooling. 

Come learn more on Thursday, May 23rd at 9:00am at @silveroakcellars.
