Calistoga, Napa Valley, January 2022 – Castello di Amorosa, Dario Sattui’s authentically-built 13^th 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.
