Ernest & Julio Gallo Winery installed computer-accessible demand control systems at two of their facilities in Fresno and Livingston. The automated system at Fresno provides real-time power monitoring and control of 12,500 tons of refrigeration chillers, five filtration systems and 24 radio-controlled portable pumps. The Livingston winery's system controls 14,000 tons of refrigeration. Tests run on the systems in October 2006 showed a potential demand reduction of 4,417 kW in Fresno and 1,791 kW in Livingston.
