The Energy Tool Database and EPC company BPi located in Napa have successfully deployed three Energy Storage Systems (ESS) at Korbel Winery in Sonoma County, California. This installation is part of the winery's broader commitment to sustainable development and the integration of renewable energy into its operations.

Energy Toolbase and BPi installed three BYD battery systems integrated with the ETB controller energy management system at the winery. The deployment of advanced energy storage systems aims to reduce demand costs, overcome grid limitations, and optimize energy usage under peak to valley electricity (TOU) billing rates in the region. The project also addressed the 980 kW AC export limit imposed by PG&E due to local substation restrictions, maximizing the use of renewable energy generation on site and achieving significant energy cost savings.

BPi implemented a limited export control strategy using SEL-751 relays and inline contactors. Energy Toolbase manages BYD batteries in real-time through an ETB controller with Acumen AI, in compliance with the parameters set by BPi in SEL relays. These controls limit exports to the upper limit defined by the power company and dynamically schedule battery power to minimize peak demand for expensive facilities. Through the dynamic economic scheduling strategy of Acumen AI, the ETB controller optimizes the operation of batteries in real time to determine the most cost-effective scheduling strategy and maximize economic value without human intervention. The ETB controller manages energy flow, peak shaving and valley filling, reduces electricity costs, maximizes on-site energy generation, and provides energy for key equipment such as refrigeration, brewing systems, filling lines, and compressors.

Energy Toolbase simplifies the procurement and commissioning process of BPi, ensuring smooth and efficient installation. The project installed 852 kilowatt solar panels on the roofs of four buildings and was equipped with three BYD CHESS devices, each with a capacity of 266 kilowatt hours and a total energy storage capacity of 798 kilowatt hours.

This project is a powerful example of how smart software combined with modular energy storage can overcome complex grid limitations and provide immediate, quantifiable value, "said Kevin Muwei, Vice President of Operations at Energy Tools. Our collaboration with BPi has played a crucial role in successfully addressing complex interconnectivity requirements and deploying solutions that have brought significant savings to Korbel
