Solar + Storage Microgrid Makes Wine-Making More Resilient

Stone Edge Farm, the original goal was to reduce their carbon footprint by 50 percent but after exceeding this in just one year, they’ve set a new goal to reduce their footprint until it is below 100 percent.

An innovative solar plus storage microgrid at Stone Edge Farm, a winery in Sonoma, California is now online. The microgrid uses solar PV + storage and is designed to provide energy for a number of buildings on the site, including the primary residence, offices and workshops. When the sun is shining, the PV provides energy for the buildings and charges the batteries. During nighttime hours and periods of cloud cover, the batteries provide energy for building loads.

The system consists of fourteen 25-kWh Aquion M-Line Battery Modules providing approximately 350 kWh of energy storage capacity, connected to a 32-kW solar array using Ideal Power’s 30-kW multi-port power conversion system. The Ideal Power multi-port system architecture enables the direct DC-level connection of solar PV and energy storage in one package. Aquion’s battery technology uses saltwater chemistry and the batteries are designed for daily deep cycling in long duration (4+ hour charge/discharge) applications.

The microgrid was developed by Wooster Engineering Specialties, a general engineering contractor. The services it will provide to Stone Edge Farm include the ability to self-consume the solar, peak shaving and load shifting. While the microgrid is grid-tied, it is capable of islanding and operating autonomously. The companies said that it also generates sufficient energy that Stone Edge Farm is able to sell a substantial amount of the energy produced back to local utility PG&E.
