In 2006, Cal Poly's partnership with EnerNOC and participation in the Demand Reserves Partnership (DRP) curtailed load for 21 hours over nine days. During one particular event on July 24, Cal Poly reduced 1.75 MW of demand, which amounts to an impressive 27% of the university's peak load. Cal Poly achieved load reductions primarily by adjusting lighting load and HVAC set points, along with a well-communicated campus-wide curtailment plan. Cal Poly simultaneously initiated a program in its energy management system to shut down non-essential HVAC loads. Overall, the University reduced its total electricity consumption by 23,000 kWh.
