In 2008 Constellation Wines U.S. implemented an intelligent energy management system, provided by Powerit Solutions, which gave rise to the largest intelligent demand response system to date. The system earned over $1 million in rebates from PG&E and helps Constellation Wines U.S. to achieve a 50% reduction in total peak demand at each of their California facilities. At the Mission Bell facility this translates to a 4,286 kWh demand reduction and at the TRV facility, a 1,017 kWh reduction. Constellation continues to work with PG&E and Powerit Solutions to reduce peak demand and invest in energy efficiency.
