WAPA congratulates customer Sacramento Municipal Utility District (SMUD) on receiving an innovation award at the annual meeting of the National Association of Regulatory Utility Commissioners (NARUC) in November.
The award for Municipal-level Innovation in Regulatory Policy recognized SMUD’s work testing a new cooling technology that significantly reduces summer peak loads. SMUD’s project was one of 10 innovation awards NARUC presented at the meeting in Baltimore, Maryland.
Widely recognized need
For summer-peaking utilities, the air conditioning load is the 600-lb. gorilla. According to a 2006 California Energy Commission report, on the hottest summer days, air conditioning alone accounts for more than 30 percent of the peak demand on the statewide electric network. Conventional rooftop-packaged cooling units—80 percent of building systems—exacerbate the heavy demand that summer air conditioning puts on the grid.
In a hot, dry climate (like much of WAPA’s territory), indirect evaporative cooling (IDEC) technology has shown strong potential for reducing peak demand. It works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate. The main difference with an indirect system is that a heat exchanger is used to cool the air supplied to the living space. The fact that the technology also uses less water than the direct method makes it even more attractive in the drought-wracked West.
IDEC cooling was an excellent candidate for SMUD’s Customer Advanced Technologies (CAT) Program, designed to help customers use and evaluate new or underutilized technologies. The CAT program pays some of the costs for installing the demonstration equipment.
Tale of two businesses
SMUD enlisted two large customers, both with cooling issues, to participate in a demonstration spanning the summers of 2014 to 2015. Tri-Tool, a custom tool manufacturer, replaced its conventional cooling system in the shop with a Climate Wizard IDEC system. Environment Synectics, which provides environmental services for the government, installed a hybrid system combining Climate Wizard units with conventional systems.
The CAT program paid for the incremental cost of the Climate Wizard over standard air conditioning technology. The units are manufactured in Australia, so between shipping costs and smaller-scale production, the initial cost of the equipment can be a barrier to adoption. But SMUD Program Manager Jim Parks observed, “If your region has enough hot days, you will get your money’s worth.”
SMUD monitored the companies’ summer energy use after the significant retrofits to determine savings compared to the Title 24 (California’s energy efficiency standards) baseline. The results from a summer of data collection indicated that both companies had reduced their energy use for cooling by around 50 percent compared to code requirements. “That falls right in the mid-range of Climate Wizard estimates of 40- to 65-percent savings,” said Parks.
The benefits of IDEC for Tri-Tool went beyond lower electricity bills. The Climate Wizard not only made the facility more comfortable, but it purged contaminated air from the shop floor. The dry air supplied by IDEC also reduced the humidity in the shop, a problem caused by the use of water in the manufacturing process.
Recognition rolls in
The NARUC award is not the first one SMUD has received for the IDEC project. APPA honored the project with its 2017 Energy Innovator Award and then nominated it for the NARUC award. “I didn’t know we were in the running until NARUC called to tell me that we won,” recalled Parks.
He added that SMUD enjoys getting the recognition. But it would be even better if the awards called attention to a product that, in the right climate, can reduce a large commercial customer’s energy use by double-digit percentages. The Climate Wizard could also help summer-peaking utilities effectively reduce their air conditioning loads. And that is better than any award.

Deadline Jan. 31, 2017
It is time to gain recognition for your energy services programs and share your success stories with your customers, communities and industry colleagues. The American Public Power Association (APPA) presents two awards annually to member utilities that embody the spirit of the association’s Demonstration of Energy and Efficiency Developments (DEED) program. The research and demonstration program funds innovative activities dedicated to improving the operations and services of public power utilities.
The Award of Continued Excellence (ACE) recognizes a DEED member utility that has demonstrated continued commitment to the DEED program and its ideals. Criteria include involvement in the DEED program, including grants and scholarships; commitment to energy-efficiency; investigation or use of renewable resources and support of public power. This year’s award presentation will take place during the 2017 APPA Engineering and Operations Technical Conference, May 7-10, in San Antonio, Texas.
The Energy Innovator Award (EIA) recognizes utility programs that have demonstrated advances in the development or application of creative, energy-efficient techniques or technologies. Projects and programs that provide better service to electric customers or that increase the efficiency of utility operations or resource efficiency are eligible, too. Judges will take into account transferability and project scope in relation to utility size.
WAPA customer Moorhead Public Service received an Energy Innovator Award in 2016 for developing its Capture the Sun community solar garden. Lincoln Electric System, Omaha Public Power District, Alameda Municipal Power and Salt River Project are other WAPA customers that have earned the award with innovative programs.
APPA may give up to three awards in a given year. The awards will be presented during the 2017 APPA National Conference, June 16-21, 2017, in Orlando, Florida.
Nominations for both the ACE and the EIA may be submitted via the web-based application process. Submissions must be received no later than Jan. 31. For questions, contact the DEED program staff at 202-467-2960 or 202-467-2942 or via email.
After completing your nomination, don’t forget to share it with Energy Services Bulletin. Every utility program has an important story to tell and all WAPA customers are winners.
