Santa Clara reaches coal-free goal in 2018

Silicon Valley Power You are leaving WAPA.gov. (SVP) reached a major milestone in the long, determined march toward sustainability when the Santa Clara, California, utility permanently eliminated coal power from its energy supply Jan. 1.

Various renewable resources and natural gas-fueled generation from Lodi Energy Center  You are leaving WAPA.gov. in Lodi, California, have replaced the 51 megawatts (MW) of coal-powered electricity SVP sourced from San Juan Generating Station in New Mexico. The move reduces the carbon intensity of Santa Clara’s power supply by about 50 percent.

Thanks to customers
The accomplishment began with both residential and business customers pushing the utility to reduce greenhouse gas emissions. SVP serves many forward-thinking corporations along with a highly educated and unusually engaged group of residents. “We launched the Santa Clara Green Power Program to meet customers’ demands for 100-percent renewable power as the state established its renewable energy goals,” stated SVP Customer Services Manager Larry Owens.

Santa Clara Green Power launched in 2004, two years after California adopted a renewable portfolio standard (RPS) and two years before the first expansion of the RPS. The city continued to monitor its emissions, evaluate resources and update its goals to stay ahead of state mandates, but mostly to meet and exceed customer expectations.

Keeping up with the expectations of business customers in the center of the technology industry has challenged SVP to keep reaching higher, too. SVP Public Benefits Manager Mary Medeiros McEnroe noted, “Many of our large key customers have corporate sustainability initiatives and have been the drivers behind some of our programs.”

Businesses subscribing to Santa Clara Green include Intel—a 62-wind turbine partner—Santa Clara University, the Great American Theme Park and the city itself. A number of large commercial customers have installed solar arrays on their facilities ranging from 750 kilowatts to 1 MW per site.

Speed bumps, fast lanes on road to success
There are pros and cons to being a leader in clean power initiatives and SVP has seen both sides as it moved toward its goal.

In 1980, SVP joined Modesto Irrigation District You are leaving WAPA.gov. and Redding Electric Utility You are leaving WAPA.gov. to form the M-S-R Public Power Agency, You are leaving WAPA.gov. a partnership that has helped all three utilities evolve with the industry. In 2006, M-S-R worked to acquire 200 MW of new wind power in Brickleton, WA. “We all saw our customers buying more green power,” Owens recalled.

It was clear to the utility partners that a cleaner power supply was the road to the future. Around 2009, as the state set higher renewable energy goals and added new regulations, other California municipal utilities followed M-S-R toward the coal off-ramp. In some ways, Owen observed, the group effort gave utilities more leverage to negotiate their exit from coal power providers. On the other hand, “The more participants, the more complexity,” he said. “And there was a lot more competition for renewable energy. Ultimately, though, the cooperation among utilities was impressive.”

SVP knew that leaving their coal provider and finding cleaner power sources to replace the 51 MW was going to be difficult. But it paid off in the end when San Juan Generating Station permanently closed down half of its units. “We expected that they would just find another buyer for that power, so SVP going coal-free turned out to have a much wider impact by actually decommissioning two of the four units,” said Owens. “That was a nice surprise.”

SVP’s innovative use of wind technology on behalf of its Santa Clara, California, customers earned it the U.S. Department of Energy’s annual Public Power Wind Award.

Future is affordable
The greatest fear that grips utilities when they contemplate a future without coal—that it will force them to raise rates—has not materialized for SVP customers.

Utilities are always retiring and acquiring purchase power contracts over time, Owens pointed out, and that will affect pricing. Shifting to the Lodi Energy Center and ramping up green power caused some upward pressures on price for SVP. In the long term, however, “The forward price curves for natural gas and renewables look better than coal,” he stated.

Switching to those resources is also an investment in meeting federal mandates to reduce carbon dioxide, nitrogen oxide and sulfur dioxide emissions, he added.

Given the many factors that shape energy costs, SVP still boasts some of the lowest electricity rates in California. The utility recently announced that there will be no rate increase for 2018, and rates are expected to remain flat for the next couple of years.

Efficiency still matters
When rates inevitably change, SVP’s strong customer relationships and menu of long-established efficiency programs will help to ease acceptance.

SVP residential customers can get rebates for efficiency measures including attic insulation, ceiling fans, electric clothes dryers, electric heat pump water heaters and pool pumps. In addition to Santa Clara Green Power, the Neighborhood Solar Program allows customers to sponsor solar installations on public buildings. SVP also provides homeowners with energy audits and loans diagnostic tools to do-it-yourselfers.

While SVP counts some of the world’s most progressive companies among its large key customers, Medeiros McEnroe said that the small commercial customers are surprisingly engaged too. “Quite a few of our small businesses support Santa Clara Green Power, from dentists to auto shops, and many have installed solar arrays on their buildings,” she said. “Sustainability is a community value in Santa Clara.”

Keeping costs down is, nevertheless, still a top concern for small businesses, so SVP offers rebates for specific systems like lighting, as well as custom measures. The utility has also partnered with the Food Service Technology Center for a program to teach food service employees to manage energy and water costs.

SVP also provides energy benchmarking to help companies understand their energy and water use and set goals for improvement. “We have been able to help many customers through free snapshot audits and by educating them about the value of purchasing energy-efficient equipment,” Medeiros McEnroe said.

A utility customer program manager’s work is never done, and sustainability will always be a moving target. Achieving the coal-free goal is impressive but there are still peaks to manage and costs to control. WAPA has no doubt that with the support of its committed customers, SVP will meet each new challenge, exceed expectations and continue to impress.

Check out tools for resource planning, program development

Everyone loves to get a new tool that will make their job easier, whether it is a power sander for refinishing furniture or a calculator to help you choose the most cost-effective renewable resource or efficiency measure. Here are some “gadgets” that might be just what you need.

Choose your clean power
The Green Power Partnership, a program of the Environmental Protection Agency, has released a new Green Power Supply Options Screening Tool to help you sort through the different supply options. There are many ways to purchase green power—such as green tariffs, competitive green power products and off-site power purchase agreements—and determining which purchasing method works for you can be difficult.

Users answer a few simple questions about their organizations, including their locations and annual energy consumption. The Excel-based tool will describe which supply options might be most feasible, according to the relevant federal, state and utility policies. Background documents accompany the tool to explain how the results are defined and the logic used to produce the result for each supply option.

Calculate equipment efficiency
The DOE Office of Energy Efficiency and Renewable Energy (EERE) created the Better Buildings Residential Program Solution Center as a repository for the lessons learned from other EERE programs dedicated to improving building efficiency. Utility program administrators will find resources here that help them plan, operate and evaluate residential energy efficiency programs.

The Solution Center has recently been branching out with more information about the technical aspects of home performance programs. A new section focused on technology solutions explores innovative technologies, offers installation guidance and estimates potential energy savings.

New pages highlight HVAC systems and heat pump water heaters, two applications that account for about 67 percent of home energy consumption. Use the reports, best practices and other resources to support program offerings and help you to reach your energy-efficiency program targets.

Identify energy savings potential
Researchers at the National Renewable Energy Laboratory (NREL) have developed ResStock, a versatile tool that takes a new approach to large-scale residential energy analysis.

The ResStock software achieves unprecedented granularity and accuracy in modeling the diversity of the single-family housing stock by combining:

  • Large public and private data sources
  • Statistical sampling
  • Detailed sub-hourly building simulations
  • High-performance computing

The research team has run more than 20 million simulations using a statistical model of housing stock characteristics. The results uncovered $49 billion in potential annual utility bill savings through cost-effective energy efficiency improvements.

Using ResStock analysis, utilities can target energy-efficiency improvements to specific customer segments to improve cost-effectiveness. Resource planners can determine which measures and distributed energy resources are best for relieving grid congestion and what housing stock segments can provide the greatest load flexibility.

Utility program managers, municipalities and state energy agencies can use ResStock to identify the most cost-effective—and energy-saving—home improvements. The tool is also valuable for helping cities and states figure out how buildings contribute to energy or emissions targets. NREL is pursuing partnerships with industry to adapt ResStock for specific utility, manufacturer, state and local applications.

NREL will be offering the ResStock software at no cost, leveraging DOE’s open-source building energy modeling ecosystem of OpenStudio® and EnergyPlus. These cloud-based collections of software tools allow users to model energy use for heating, cooling, ventilation, lighting and plug-and- process loads without a supercomputer.

ACEEE releases third, final video in ‘Health and Environment’ series

Energy Retrofits Clear the Air in Pittsburgh, You are leaving WAPA.gov. the final installment in a three-part video series from the American Council for an Energy-Efficient Economy (ACEEE), is now available to watch online.

The videos share the stories of homeowners in three eastern states, and the effect energy-efficiency upgrades have had on their lives. The theme running through the series is that reducing energy waste lessens the need to burn fossil fuels to generate electricity. Those cuts deliver big gains in health, because pollutants from burning fossil fuels contribute to four of the leading causes of death in the United States: cancer, chronic lower respiratory diseases, heart disease and stroke.

The series is part of ACEEE’s new Health and Environment program, launched last year to research the linkages among health, environment and energy efficiency, and to educate policymakers. Later this year, ACEEE will release a series of reports that will further explore the health and environmental benefits of saving energy.

A two-day Conference on Health, Environment & Energy ACEEE is planning for December will showcase the research and promote others’ work in this growing field. Utilities are welcomed to attend the conference in New Orleans to add their voices to this critical conversation.

Warm up with DOE’s winter home tips

Energy Saver is the U.S. Department of Energy's consumer resource on saving energy and using renewable energy technologies at home. Check out the website, blog and Energy Saver Guide for consumer education material.

Around this time of year, we are all getting fed up with cold weather and the high utility bills that come with it. Your customers might appreciate some suggestions for saving money and keeping warm over the next few (or, in some places, several) weeks. The DOE Office of Energy Efficiency and Renewable Energy has just the thing for your website or bill stuffer.  Here are simple steps we can all take to stay warm.

1. Spruce up the fireplace
Before you build that cozy fire and settle in with a good book and a hot beverage, give your fireplace some love.

Replacing your inefficient wood-burning fireplace with a more efficient wood stove or gas insert can turn your pretty–but high–maintenance—fireplace into a viable way to heat your home. Converting your fireplace will not only save you on monthly heating costs, it can improve air quality in your community. It could even put money back in your pocket—some states offer rebates or tax credits for upgrading your inefficient fireplace.

If you aren’t ready to update your fireplace, try adding glass doors with a heat-air exchange system. Make sure your fireplace is cleaned and your flue damper properly sealed. Also, try to keep the fireplace damper closed when you don’t have a fire burning to keep heat from your furnace from going up the chimney.

2. Reverse your fan
The same ceiling fan that helps to keep you cool in the summertime can also help circulate warm air in the winter. Look for a little switch on the motor housing to reverse the direction of your fan, pushing warm air down and recirculating it through the room. How do you ensure that your fan is spinning in the correct direction? When you look up, the blades are spinning clockwise.

3. Protect your lawn so it can protect you
Properly planned landscaping can save you energy and increase your home’s comfort. Windbreaks can help keep your heating bills under control by blocking the cold winter wind around your home. A wall or fence, evergreen trees and shrubs planted on the north, west and east sides of your home can be most effective in creating a windbreak and reducing heating costs.

Especially in some parts of the West, wet spring snowfall can snap branches that provide cooling shade during the summer. Worse yet, a broken branch could fall on a power line and cause an outage in the neighborhood.  Use a broom or a mop to shake the heavy snow off tree branches and relieve some of the weight.

4. Air-seal then insulate
Reducing the amount of air that leaks in and out of your home is one of the most cost-effective ways you can cut heating and cooling costs, improve durability, increase comfort and create a healthier indoor environment. Caulking and weather stripping are two simple and effective air-sealing techniques that offer quick returns on investment, often one year or less

5. Windows, windows, windows
Your windows do more than provide a view of snow-covered yards. They also provide a barrier to the cold. Windows with low-e coating reduce heat loss and even reflect back part of the room’s heat. Installing storm windows can also reduce heat loss through windows by about 10 to 20 percent.

If replacing windows is too big an investment, return to Step 4 and put some fresh calking around the panes and sill. Choose window coverings designed to help improve the performance of old windows. As a bonus, your home will get a little spring facelift to help you through the last dreary weeks of winter.

Fargo wins energy prize, Fort Collins takes second place

After nearly three years of competition, the Georgetown University Energy Prize You are leaving WAPA.gov. (GUEP) announced the winners, and the top honors go to cities served by WAPA customers. Fargo, North DakotaYou are leaving WAPA.gov. took first place, receiving a prize package that includes support toward $5 million in financing for an energy efficiency dream project. Fort Collins, You are leaving WAPA.gov. the only Colorado city to advance to the final round, came in second.

Over the course of the competition, Fargo reduced its overall energy consumption by more than 172 billion Btu, to rank fourth among the 50 semifinalists’ overall energy scores. In the final round, the judges evaluated the 10 top- performing cities and counties on their energy-saving approach, performance and prospects for nationwide replicability and scalability.

Lose-A-Watt,” You are leaving WAPA.gov. as Fort Collins dubbed its two-year energy reduction campaign, saved the community more than 160 billion BTUs of energy and reduced carbon emissions by 34,436 metric tons. The contest targeted electricity and natural gas use by residential and municipal and K-12 sectors.

Multi-faceted competition
The beauty of GUEP is that it gave America’s small- to medium-sized towns, cities and counties a way to rethink how they use energy. To reduce their energy consumption, the communities:

  • Implemented bold new local policies on energy-transparency, energy-savings and clean energy technology.
  • Conducted deep data mining of their energy use and community infrastructure.
  • Focused on increasing energy efficiency in neighborhoods with high energy use in all income brackets.
  • Created novel financing mechanisms to enable their residents to invest in new energy upgrades.
  • Used radically unique approaches to change behavior and help communities rethink their energy-use habits, including gamification and the latest methods in social science research.

Starting in April 2014, communities across the country applied to participate and filed detailed long-term plans once accepted into the competition. From January 2015 to December 2016, semifinalists competed to reduce their utility-supplied energy consumption in a way that might yield continuing improvements in their own communities and could be replicated by others.

Judges selected the finalist communities in 2017, based on energy saved during the two-year period. The winner was selected by combining those results with scores in weighted categories, including innovation, potential for replication, likely future performance, equitable access, community and stakeholder engagement, education and overall quality and success.

Teamwork creates success
Fargo’s program was built on a partnership between the city, North Dakota State University You are leaving WAPA.gov. (NDSU) and the utilities Xcel Energy and Cass County Electric Cooperative You are leaving WAPA.gov. (CCEC). Putting together a team where each party brings a particular expertise to the table was critical to Fargo’s success, said Malini Srivastava, an assistant architecture professor at NDSU. “The university researched and designed the projects to lower energy use, the utilities supplied data for benchmarking and the city provided the communication network to engage the citizens,” she explained.

CCEC had recently installed an automated metering infrastructure that collects data in up to 15-minute intervals. Having a clear picture of electricity use by homes, apartments, schools, park districts and municipal buildings proved to be very beneficial in moving the project forward. “The meter data definitely increased the likelihood of Fargo winning the Georgetown University Energy Prize,” said CCEC President and CEO Marshal Albright.

Engaging online, in person
Srivastava, the project lead for NDSU, created another important piece of the city’s strategy, eFargo. The web portal engaged the community with games and a narrative. “Gaming made saving energy fun and easy to understand,” said Fargo Planning Director Nicole Crutchfield. “eFargo was a great way to educate students and the general public about energy efficiency.”

The website attracted more than 300 participants to play the open game during eight weeks. The school game was even more successful, with more than 1,500—mostly students—participating over a six-week period. “We challenged local schools to defeat the Waste-a-Watt character by using their knowledge about energy and creativity,” Albright said. “The schools competed to reduce energy consumption over six weeks. Fargo’s Roosevelt Elementary won the challenge, reducing the school’s energy consumption by 29 percent.”

Getting school children involved was the most effective outreach, Crutchfield noted, but engaging citizens at libraries, public events, churches and other faith-based groups also paid off. Local experts in energy production and distribution joined the advocacy effort, forming the Citizens’ Local Energy Action Network—CLEAN—to advocate for renewable energy and evolving technologies in transportation.

Upping their building game
Another project that helped secure the top honor was designing affordable “passive houses” Fargo hopes to develop in partnership with a builder. NDSU architecture students researched and designed four high-performance homes. “The students did professional-level work, and I think it was educational for them to watch the city work through the permitting process,” Crutchfield said.

Other initiatives included providing financial assistance to low-income homeowners for weatherization and to preserve existing housing stock in the city’s older neighborhoods. Fargo also adopted and is actively enforcing the 2015 International Energy Conservation Code. The city hopes to keep working with NDSU on coming up with creative ways to reinforce our housing stock. “That is one possible use for the prize,” Crutchfield said.

Words matter
The city of Fort Collins, a long-time leader in municipal sustainability, used the GUEP competition as an opportunity to hone some existing programs and strategies and to test new ones. Fort Collins Utilities (FCU) and the city’s Environmental Services led a campaign built on climate action goals that are already reducing the community’s environmental impact.

One particular area of success, according to Fort Collins Sr. Environmental Planner Katy McLaren, was in tightening up and lightening up the language in outreach material. “We built our messaging around specific actions and limited seasonal campaigns to three actions,” McLaren said.

Social science-based marketing approaches informed the Lose-a-Watt campaign but the website avoided utility jargon to engage visitors with lighter, more fun language. Those lessons will be incorporated into the city’s future marketing and outreach campaigns, noted McLaren. “I think other utilities could benefit from looking at how we framed the efficiency actions, as well as the use of lighter language in messaging,” she added.

Many ways to save
The Lose-a-Watt website provided Fort Collins residents with a variety of options for taking action to reduce their energy use, some established and some launched for the competition. Homeowners could make home performance upgrades with Efficiency Works Neighborhood, a pilot program that streamlined the utility’s rebate process for efficiency improvements. “FCU moved it to full program status and will continue to refine it going forward,” McLaren said.

Volunteers for the Lose-a-Watt Porchlight Campaign went door to door, offering to replace incandescent bulbs in porch lights with a free LED bulb.

Residents who were inspired to volunteer could join the Porchlight Campaign. Volunteers visit neighborhoods around the city to see what type of light bulbs homes have in their porch light fixture. If a home’s porch light has an incandescent bulb, volunteers offer to replace it with a free LED bulb.

The Workwise ChallengeYou are leaving WAPA.gov. got the business community involved in the competition by giving businesses free home conservation kits to hand out to their employees. The business with the most employees installing kits received prizes and recognition. Utility representatives used the challenge as an opening to introduce commercial customers to ClimateWise, the city’s free, voluntary program to help Fort Collins businesses reduce their environmental impact.

Some things work, some don’t
As with Fargo, Fort Collins found engaging students to be the “biggest bang for the buck.” Poudre School District worked with the city to present the Voltbusters education program for K-3 grades. “The kids take the information home to share with their parents, and the parents are much more interested because their kids are into it,” McLaren echoed Crutchfield’s observation.

The Voltbuster Challenge enlisted Poudre Valley students to save energy. Both GUEP winners said that getting children involved in a program is an effective way to reach parents.

Gaming—specifically a gaming app created by Joulebug You are leaving WAPA.gov.—was less of a success for Fort Collins. “It would probably have been more effective if we ran it for one year, instead of two,” McLaren said.

Overall, maintaining the community’s level of engagement for the duration of the competition proved challenging, McLaren acknowledged. The fact that Georgetown University struggled to keep its dashboard updated with progress reports did not help, she said.

Worth effort
Both cities saw the competition as a positive experience that gave them permission to experiment with new ideas and pushed them to communicate more with residents about energy use.

Srivastava agreed with Albright about the importance of having detailed energy-use data to measure programs. She is currently preparing a report on the competition to present at a conference in the spring, and is looking forward to sharing Fargo’s lessons with other cities. Perhaps the greatest lesson the Georgetown University Energy Prize winners learned, said Srivastava, is that, “Small cities shouldn’t be afraid of trying new ideas.”

WAPA congratulates Fargo and Fort Collins on their creativity and initiative, and we look forward to seeing how they build on their success.

The session gives power providers and government representatives their own time to candidly discuss issues that concern them, strictly from their own point of view. “The UEF attracts a lot of trade allies and representatives from related field, but it is first and foremost for utilities,” explained WAPA Energy Services Manager Ron Horstman. “Giving utilities a chance to ‘talk amongst themselves’ first sets the tone for the meeting. They go into the forum with a clear idea of their shared challenges and what they hope to learn.”

Join us!
The UEF is a California-centric event, but don’t let that stop you from attending. You may have more common ground with West Coast utilities than you realize.

It is a great opportunity to network with energy services colleagues and learn about their customer programs related to energy efficiency, renewable energy, key account management and other customer services. This year’s theme, Preparing for the New Energy Future, asks us to challenge our traditional thinking to be ready for the rapidly changing energy utility industry.

The Double Tree Hotel in Rohnert Park, California, will host the UEF this year. The registration rate includes not only your conference registration, but your lodging and all your meals. The views of the Sonoma Wine Country are free.

Horstman will be attending the UEF and moderating the Pre-Forum Workshop along with Paul Reid of Azusa Light and PowerYou are leaving WAPA.gov. so attendees will get to share their thoughts and concerns about WAPA as well. Your Energy Services Bulletin editor (me) will also be on hand to hear your stories and pick your brain about services you would like us to offer. We look forward to meeting WAPA customers and learning all about your challenges—and your innovative solutions—April 25-27.

OPPD program harnesses smart thermostats for savings

Wi-Fi-enabled thermostats give homeowners unprecedented opportunity to control their energy use, and Omaha Public Power District You are leaving WAPA.gov. (OPPD) has now created a program that rewards customers for sharing that control with the utility.

The Nest thermostat™ can learn homeowners’ behaviors, keep the house comfortable and save money on energy bills.

Different kind of demand response
Residential customers who have installed, or who plan to install, Nest thermostats™ are eligible to enroll in “Nest Rush Hour Rewards.” They receive a $100 credit on their electric bill for enrolling in the program and an additional $20 credit annually.

On certain days in May through October, when demand for electricity is high, OPPD may declare a Rush Hour event during which Nest adjusts participants’ air conditioning through their thermostats. This can occur for up to four hours, between noon and 9 p.m. Participants generally have two hours’ notice before the event, giving Nest time to pre-cool the home. OPPD may schedule critical Rush Hour events in an emergency, where customers would receive a 10-minute notice.

Customers don’t need to be home to turn down their heating or cooling and if they get uncomfortable during the Rush Hour, they are able to adjust their home temperature remotely.

Automation makes it easy
Nest Rush Hour Rewards You are leaving WAPA.gov. is a partnership between the smart-thermostat manufacturer and energy providers. By teaming up with Nest, utilities gain a tool for lowering demand while helping consumers get the most value from their investment.

The OPPD request for proposals (RFP) for a smart-thermostat program called for a cost-effective, easy-to-use unit that had high acceptance in the marketplace. Jay Anderson, project director for OPPD’s Power Forward Initiative, noted that Nest best matched the RFP’s criteria. “We will consider other thermostats as we learn from operating the program,” he said.

Nest is among the most popular interactive thermostats on the market today. It can learn homeowners’ behaviors, keep the house comfortable and save money on energy bills. Homeowners can adjust their heating and cooling systems remotely and allow their power providers to do the same.

Part of big picture
The Thermostat Program is part of a broader initiative OPPD launched with the goal of reducing demand by 300 megawatts (MW) by 2023. “Reducing our need for electricity, when demand is at its highest, helps reduce our need to purchase electricity or build a new power plant,” said Anderson. “And that helps keep costs down for all of OPPD’s customers.”

OPPD is not relying on smart thermostats alone to achieve such an ambitious goal. The initiative encompasses programs that tackle commercial and industrial, as well as residential loads. The utility’s Cool Smart program currently controls 60 MW of residential air conditioning, not including the Nest thermostat™ program. Cool Smart participants must cancel their enrollment in that program before signing up for Nest Rush Hour Rewards. “The two programs use different strategies to curtail the same load, so there are no additional savings to be gained from participating in both,” Anderson explained.

The Thermostat Program and Cool Smart are the only residential demand response programs that OPPD offers at this time. But the “bring-your-own-device” model for Rush Hour may prove to be a way OPPD can adapt to a rapidly changing marketplace. “This allows us to see what customers are interested in and add new technology to our efficiency programs as it makes sense,” said Anderson.

Smart technology offers many potential benefits to the consumer who is willing to try something new. Omaha Public Power District, a smart utility, is discovering it can share in those benefits by rewarding its customers’ pioneering spirit.

ACEEE video series links energy efficiency, public health

Oh, energy efficiency! Is there anything you can’t do? As if saving consumers money and managing our loads isn’t enough, a video series by the American Council for an Energy Efficient Economy You are leaving WAPA.gov. (ACEEE) makes the argument that more efficient buildings play a role in keeping us healthy.

Utilities across the nation are greening their portfolios by adding more renewables and distributed generators as the technologies become more affordable. However, just as the kilowatt-hour you don’t use is the cheapest, it is also the cleanest. The ACEEE series highlights a benefit of energy efficiency that often gets little attention, especially on the personal scale.

Each video presents a case study on how weatherization has helped to improve the health of homeowners and their families. The series launched in December 2017 with a video about a senior citizen living in a trailer in rural West Virginia. After a local anti-poverty program weatherized her home, the woman’s chronic breathing problems eased and her utility bills decreased.

Part two, released this month, shows how better insulation and air sealing have improved a child’s asthma condition in Baltimore. The series will conclude in February with a look at how weatherization is mitigating the effects of outdoor pollution in Pittsburgh. All videos will be available on ACEEE’s website.

In March, ACEEE will release The Next Nexus: Exemplary Programs That Save Energy and Improve Health, a report detailing programs nationwide that work to improve public health by improving building health. These programs represent potential partners for utilities and municipalities seeking to promote weatherization and other building efficiency initiatives. The report also highlights the non-energy benefits of weatherization—such as improved comfort and indoor air quality—helping utility program managers build a stronger case for efficiency upgrades.

If the report whets your appetite to learn more about the intersection of energy efficiency and public health, ACEEE is hosting its first Conference on Health, Environment and Energy in New Orleans in December. The event will offer many opportunities to network and brainstorm with other professionals in these fields. It is time to share the news that reducing energy waste is not only good for your bottom line, it is good for your community.

New clothes washer efficiency standards take effect in 2018

Newly-manufactured clothes washers for homes, multi-family buildings and laundromats are good candidates for customer incentive programs aimed at saving energy and water.

Clothes washers meeting the new standards provide not only significant energy and water bill savings, but also better cleaning performance and more features than older washers.

Clothes washers meeting the new standards provide not only significant energy and water bill savings, but also better cleaning performance and more features than older washers.

Efficiency standards taking effect Jan. 1, 2018, will reduce energy use in residential top-loading clothes washers by 18 percent and water use by 23 percent. The standards for the generally more efficient front-loading washers were increased in 2015 and will remain unchanged in 2018.

Combined, the changes in the 2015 and 2018 standards will eliminate the need for 1.3 gigawatts of electricity generating capacity over 30 years, according to a Department of Energy estimate. That is roughly the output of two average-sized coal plants. For water utilities, the new appliances will save 3 trillion gallons of water over the same period of time, and consumers can net up to $30 billion in savings.

Commercial washers, of the type used in multi-family buildings and laundromats, will see energy use reductions of 15 percent for top-loading models and 18 percent for front-loaders. The standards will also cut the water consumption of front-loaders by 20 percent, while the water use of top-loaders will remain essentially unchanged.

SMUD recognized for innovation at gathering of state utility regulators

WAPA congratulates customer Sacramento Municipal Utility District You are leaving WAPA.gov. (SMUD) on receiving an innovation award at the annual meeting of the National Association of Regulatory Utility Commissioners You are leaving WAPA.gov. (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, You are leaving WAPA.gov. 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 You are leaving WAPA.gov. 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 You are leaving WAPA.gov. (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 You are leaving WAPA.gov. 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.
