Automated Demand Response Comes to San Antonio

March 28, 2014 By William Opalka

HoneywellWhat may be the largest automated demand response (ADR) program by a municipal utility is coming to San Antonio as Honeywell and CPS Energy embark on a two-year program after a successful pilot last year.

The utility will use technology and services from Honeywell to connect and collaborate with commercial and industrial customers to adjust electricity consumption during demand peaks. CPS will have additional tools to stabilize the Texas grid on hot summer days when air conditioners are likely to be running at capacity.

Last year’s pilot included nine commercial and industrial facilities, and helped trim demand by about 1.5 MW, or a more than 10 percent reduction in each building on average. Honeywell and CPS Energy want to enroll 60 additional sites, bringing the potential reduction to nearly 6 MW.

If successful, the utility would be able to defer construction of peaking plants that are used only on those occasions when demand is highest.

As part of the program, Honeywell will identify and enroll customers, audit their buildings to identify curtailment opportunities, and work to customize and implement changes that trim energy use, but don’t impact core business functions. In return for joining, customers receive an incentive for each kilowatt they’re able to shed. The hardware and software installed can also help each organization better manage electricity use every day and boost long-term energy efficiency.

Honeywell will also provide its Akuacom Demand Response Automation Server, software as a service (SaaS) that enables CPS Energy to send signals to building automation systems at sites enrolled in the program, triggering the short-term load-shedding measures the customer.

Honeywell also manages a residential demand response for CPS Energy, which started in 2004 and now involves more than 81,000 homeowners.
