NV Energy has enrolled some of its largest customers in Las Vegas including casinos, government and commercial buildings. The cloud-based software receives electronic signals from NV Energy and automatically manages demand response events for customers without disrupting operations.
The utility has reduced peak HVAC power consumption in buildings by as much as 20 percent on demand response event days, according to BuildingIQ. The program has lowered on-going daily HVAC energy use for customers by 10 to 18 percent compared to baseline, the software company says.
For example, M Resort Spa Casino achieved a 12 percent reduction in HVAC energy use last month through the software program, which allows NV Energy to communicate directly with the resort to make real-time adjustments and optimize energy storage. M Resort Casino uses the BuildingIQ in its offices, conference space, restaurants and casino areas.
NV Energy is using BuildingIQ as part of its larger mPowered Optimization program, in which customers receive access to the software and associated energy savings in return for participating in DR events. The mPowered Optimization program, which was launched in summer 2013, has boosted energy efficiency in its customers’ facilities, while providing significant peak load reductions for the utility.
NV Energy upgraded the lighting at 152 of the schools in the Clark County School District in Las Vegas—the fifth-largest in the nation. NV Energy partnered with the 357-school district for the upgrade, replacing existing fluorescent lights and ballasts with new T-8 fluorescents and ballasts at older schools with the least efficient lighting.
The project was completed in December 2011, and the school district has seen savings of 21.4 million kWh annually since the retrofit, which equates to $2.25 million per year, according to Dick Cuppett, energy manager with the Clark County School District.
In fiscal 2012, the district earned $790,000 in utility rebates for reduced electricity use to help offset its approximately $40 million per year utility bill.
