Plan your celebration for Energy Efficiency Day 2017

Oct. 5 is fast approaching, and the message for Energy Efficiency Day 2017—save energy, save money—is one your customers will surely appreciate.

Following the success of last year’s first-ever national event, the American Council for an Energy Efficient Economy You are leaving WAPA.gov. is looking to expand participation and awareness of the event. More than 175 were official supporters in 2016. Your utility could join the more than 175 government agencies, companies, power providers, cities and other organizations that supported Energy Efficiency Day in 2016.

Outreach includes a website, a Facebook account, You are leaving WAPA.gov. more official declarations and a challenge to save energy in homes and businesses. An ACEEE blog post  lists four suggestions for challenging your community to save energy.

  • Sign up on the new event website You are leaving WAPA.gov. as an individual or as an organization. You will receive ideas and fun facts to share on social media as Energy Efficiency Day gets closer.
  • Urge your residential and commercial customers to take the Lightbulb Challenge or the Office Lighting Challenge.  Challengers agree to replace at least one light bulb with an LED. If each US household purchases just one LED bulb, consumers could save $500 million annually.
  • Share your own energy efficiency story. Promote your news about Energy Efficiency Day and the benefits of saving energy–and money–through blog posts, emails, newsletters and social media. Create your own content with videos, photos, graphics or other messages. Sign up on the EE Day website to get more material you can use from ACEEE.

You can use your imagination, too–creativity and humor are welcomed. And don’t forget to share your ideas with ACEEE and WAPA. We would love to highlight your activities in an Energy Services Bulletin story.

ACEEE blog series explores energy-efficiency investments in US

Stacks of American dollar billsEnergy efficiency is a big and growing business with $231 billion invested globally in 2016, according to an estimate by the International Energy Agency You are leaving WAPA.gov. (IEA). The American Council for an Energy-Efficient Economy (ACEEE) used the release of the IEA Worldwide Investment report in July as a springboard to examine how much the United States invests in energy efficiency, what is driving that investment and how it could be increased.

We spend how much?
The first blog post, How Many Billions do US Businesses and Individuals Invest in Energy Efficiency Each Year?You are leaving WAPA.gov. gave $41 billion as the estimated figure for efficiency spending in our country. This was the first year that the IEA report gave a separate estimate for the U.S., but spending was not broken out by sector. Based on the worldwide estimate, about 58 percent of that spending is for buildings, 26 percent for transportation and 16 percent for industry.

Drawing on other spending reports to get a clearer picture, ACEEE concludes that our energy-efficiency investments may actually range from $60 billion to $115 billion annually. This wide-ranging estimate results from different studies employing different measurement methods and parameters. However, additional research by ACEEE and by the U.S. Green Building Council You are leaving WAPA.gov. suggest this range is reasonable.

Policy appears to be the primary driver in energy-efficiency investments, with building codes and appliance and vehicle standards responsible for about $20 billion worth. “Spillover” occurs when policies and programs, such as utility incentives and customer programs, indirectly influence consumer decisions.

Reasons why
Other factors driving the decision to invest in energy efficiency include income and education levels among residential consumers and type of industry for business customers.

Who Invests in Energy Efficiency and Why?, the second blog post, cites a survey by the U.S. Energy Information Administration (EIA) showing that large firms are more likely to engage in energy management activities than small companies. Businesses participating in the Shelton Group’s 2016 B2B Pulse study You are leaving WAPA.gov. rated how important sustainability and conservation were to their company’s operating and capital expenditure decisions. Commercial real estate development and property management were the industry groups that gave energy issues the most consideration.

The EIA’s 2015 Residential Energy Consumption Survey found that consumers with higher incomes are more likely to make energy-efficiency investments large enough to be eligible for federal energy-efficiency tax credits. Smaller investments, such as new lightbulbs, do not appear to be affected by consumer income. Another study found an education effect along with the income effect, but income and education are usually closely related. Households that have moved within the last three years spend more on efficiency improvements, as do younger families.

The reasons commercial customers offer for making efficiency upgrades, while not unexpected, show a subtle shift in priorities. From the Shelton Group study, business customers cited “energy savings or other cost reductions” as the leading motivation for investing in efficiency. Although concern about climate change ranked toward the bottom of the list, the percentage of respondents that mentioned it has nearly doubled in the last year.

Saving on electric bills also topped the reasons residential customers gave for undertaking energy-efficiency improvements at 61 percent. Making the home more comfortable followed with 35 percent and making the home healthier was mentioned by 27 percent of respondents. Taken together, comfort and safety are an equal consideration to financial concerns. The study recommends focusing homeowners on both the financial and non-financial benefits of energy efficiency to explain the value of their investment.

Let’s do more
The final post addresses the question on every utility program manager’s mind—How Can we Increase Energy Efficiency Investments?—and offers 10 suggestions to make it happen. According to ACEEE, only about one-quarter of households and businesses implement efficiency upgrades, in spite of the benefits.

The suggestions focus on expanding what is already working, while remaining open to new approaches. More measurement and benchmarking could help program providers identify successful programs and help customers see the value of energy-efficiency improvements. The article also recommends seeking partnerships with real estate, financial and construction industries to reach consumers through different channels.

Energy-efficiency investments were 8-9 percent higher in 2016 than in 2015. The ACEEE blog series offers some starting points to help utilities keep the momentum going. Energy Services looks forward to hearing about your ideas for getting more results from your existing programs and for creative new service offerings.

Conference highlights initiatives worth imitating

Rocky Mountain Utility Efficiency Exchange
Aspen Meadows Resort
Sept. 27-29

Rolling into its second decade, the Rocky Mountain Utility Efficiency Exchange You are leaving WAPA.gov. has now been around long enough for its many participants to see the fruits of meeting annually to swap program ideas and stories of successes and failures with colleagues from across the region.

Utility program managers will be gathering at the Gold LEED-certified Doerr-Hosier Center at Aspen Meadows Resort Sept. 26-29 to share their ideas for taking customer efficiency programs to the next level.

Forward-looking agenda
This year’s theme, “Initiatives worth Imitating,” focuses on using lessons learned from past programs to address the new issues and opportunities utilities are facing. Programs incorporating time-of-use rates, community solar, the internet of things and big data will be in the spotlight. Sessions will also cover new spins on demand response, customer outreach, behavior change and incentive programs.

“Technology often integrates tools and strategies that were part of successful energy-efficiency and load management programs in the past,” explained Energy Services Manager Ron Horstman. “Load management today and going forward requires updates and changes in approach that will maximize the new resources and technology that are constantly being introduced to the industry. This year’s agenda encourages that kind of thinking.”

The future is on the minds of keynote speakers, too. Mark Martinez, the senior portfolio manager for emerging markets and technologies with Southern California Edison You are leaving WAPA.gov. will deliver the opening keynote, Preparing Today for an Integrated Demand Side Management Future. He will draw on his more than 25 years of experience in the design, management and evaluation of electric demand side management (DSM) programs to present a vision of how DSM needs to change.  

The closing keynote by Ellen Steiner, the vice president of Opinion Dynamics You are leaving WAPA.gov., will explore how utility customer programs can adapt to meet the needs of changing demographics. A master methodologist, Steiner has strong energy-efficiency industry experience encompassing workforce education and training, marketing, community outreach and HVAC program design and evaluation.

Hear from your peers
New and familiar faces host the regular sessions, including the dual track residential and commercial sessions on Thursday. Sponsors the City of Aspen You are leaving WAPA.gov. and Holy Cross Energy You are leaving WAPA.gov. will join Fort Collins Utilities You are leaving WAPA.gov., Colorado Springs Utilities You are leaving WAPA.gov., Nebraska Municipal Power Pool You are leaving WAPA.gov. and many more regional utilities to talk about the state of customer programs in 2017. Research agencies and nonprofits like Rocky Mountain Institute You are leaving WAPA.gov. and National Renewable Energy Laboratory team up with program vendors such as CLEAResult You are leaving WAPA.gov., Franklin Energy You are leaving WAPA.gov. and Nexant You are leaving WAPA.gov. to discuss the latest services and solutions available to help utilities manage their loads.

Friday offers a special treat with a focus on electric vehicles and storage. These topics were overwhelmingly popular at the 2017 Utility Energy Forum in California, and Rocky Mountain area utilities will be facing the same issues sooner than we expect.

Network toward your goals 
If the sessions are a great way to explore the nuts and bolts of program design and delivery, the networking opportunities let you take the pulse of the regional industry.

In addition to breaks and meals (pack your “comfortable” business casual wear), attendees will have plenty of time to mingle with their colleagues and swap ideas. On Wednesday, Sept. 27, grab a snack and a beverage and check out the poster session reception. These mini-presentations allow attendees to talk one-on-one with presenters about topics as diverse as community solar, connected home devices and infrastructure planning.

Relaxed networking continues Thursday night at the Limelight Hotel in downtown Aspen. This venue provides a low-key atmosphere where it is easy to carry on a conversation. If you hatch dinner plans at the end of the evening, the city’s world-class dining options are close by, or, you can catch an airport shuttle from the hotel lobby if need to depart early.

Enjoy Aspen
Of course, it would be a shame to cut your conference experience short, between the intriguing Friday sessions and the pleasures of September in the Rockies. We can’t promise good weather, but, most years, the days have sparkled with sunshine and fall colors and the nights have been crisp and clear.

Aspen Meadows Resort is now sold out, but you can still stroll the grounds. The city is close enough that you could park your car at your hotel and walk off the delicious meals—included in your registration fee—on your way to and from the conference.

If you need one more reason to attend the Rocky Mountain Utility Efficiency Exchange, the Building Performance Institute You are leaving WAPA.gov. awards continuing education units (CEUs) for many of the sessions. Download the instructions to find out how to verify your attendance.

UNL embraces proven storage technology to control costs

As in life, so it is in energy storage: maturity is often not considered very sexy. With all the attention lately being showered on lithium-ion battery energy storage systems, we might forget to consider an effective storage technology that has been around awhile. However, the facilities systems team at the University of Nebraska–Lincoln You are leaving WAPA.gov. (UNL) is showing its appreciation for maturity by planning a new chilled-water thermal energy storage (TES) cooling system at its City Campus.

Shaving the peak
Like many satisfied TES cooling system owners, including the California State University system You are leaving WAPA.gov. with 19 TES installations on 14 campuses, UNL is a repeat customer. The university’s first experience with the technology was a 2.4 million-gallon system installed at its East Campus location in 2009.

As the largest load served by Lincoln Electric SystemYou are leaving WAPA.gov. UNL was looking for a way to lower its high demand charges. TES uses off-peak electricity to chill water for cooling a building or a group of buildings during the hottest time of day when electricity is most expensive. “Electricity rates are not usually the driver for installing TES, especially in a state like Nebraska where electricity is very inexpensive,” explained Lalit Agarwal, interim director of utility and energy management for UNL’s facilities systems.

The City Campus TES will save UNL between $800,000 and $900,000 annually in demand savings by shifting chilled water production from peak to off-peak hours. Agarwal suspects that there are additional savings because chillers run more efficiently at night when it is cooler. “But we are not hanging our hat on those figures,” he added.

Right technology for right place
Before finalizing the decision to build a second TES cooling system on the City Campus, the facilities team weighed other options. Cool Solutions, a thermal energy storage consulting company, performed a scoping study for UNL.

The new thermal energy storage tank is located on the north side of City Campus, immediately south of the Devaney Sports Center (left) and Nebraska Innovation Campus (right).

In addition to being extremely cost effective, TES leads the other technologies in such areas as safety, ease of permitting and life expectancy. Siting flexibility is another advantage TES offers that was particularly important for UNL, as the City Campus is “landlocked,” observed Agarwal. “There is a certain amount of NIMBY-ism [not in my backyard] involved with other types of systems and only so many places we can build,” he acknowledged.

Related to the siting issue is the ease with which TES can be expanded. The system will be located on the edge of the campus and have oversized piping so it can be expanded in the future. Stefan Newbold, director of UNL Engineering Services, pointed out that the ideal time to look at installing TES is when a chilled water plant is already close to reaching its capacity. “It grows chilled water capacity significantly,” he explained. “TES is economical anyway, but it becomes more so when you throw in not having to expand a chilled water plant.”

Findings from the Cool Solutions study made up the basis of an article in District Energy’s quarterly newsletterYou are leaving WAPA.gov. The story also included a comparison of TES with a hypothetical battery system.

Tried and true pays off
The new TES system, which has four times the capacity of the East Campus plant, will be commissioned over the winter and spring, and be ready for the 2018 cooling season. The system controls will be centralized to eliminate the need for additional staff and to minimize new demands on existing staff. Using existing infrastructure and operators who already have chiller experience is another way the technology keeps costs down.

As the grid and the power supply continue to evolve, large facilities and municipalities will have to look at new solutions for managing their energy use. And while every end-user faces different circumstances, UNL’s story is a reminder that sometimes the best answer to a new challenge is an “old” idea.

White paper, training explore evolution of demand response

Utilities have long used demand response to deal with high wholesale electricity prices or generation shortfall. What was once accomplished with phone calls to large industrial customers or one-way controls on aggregated residential loads is now done in near-real time with sophisticated two-way communication. Yet, despite the fact that this strategy has become an integral part of grid operations in the U.S., there has been no agreement on a definition of demand response.

The Peak Load Management Association You are leaving WAPA.gov. (PLMA) set out last year to develop a consistent definition for demand response to use across its three training courses on the topic. A demand response dialogue that included several experts in the field took place in September 2016 and was recorded and archived on the PLMA website. At the 2016 PLMA conference later that year, the discussion continued with a panel presentation, Defining the Evolution of Demand Response: From 1.0 to 3.0 and Beyond.

Demand response evolution

Three epochs
The white paper from these discussions breaks down demand response into three periods beginning with the first interruptible tariffs for large commercial and industrial customers. Demand response was primarily used to provide energy (MWh) and capacity (MW) during periods of high wholesale prices, shortfall of generation or transmission capacity or unexpected emergency grid-operating situations. Utility staff contacted a commercial customer, usually a day or hours ahead of a forecasted event, to manually change power consumption onsite. Also, residential customers voluntarily allowed utilities to install load-control devices to cycle their water heaters and air conditioners. Verification usually came from the utility meter which was read on its regular cycle.

Current demand response strategies provide more precise energy and capacity to support the wholesale marketplace, along with sophisticated, near-instantaneous ancillary services such as non-spinning and spinning reserves and frequency and voltage support. Measurement and verification occur in almost real-time measurements (either utility or non-utility) and often serve as confirmation of customer performance during demand response events. Two-way communication also allows for greater customer feedback and engagement.

Demand response is evolving to be a component of broader distributed energy resources both behind and in front of the meter. The service benefits demand response offers in this capacity, both to the grid operator and to the customer, include volt/var control, renewable energy integration and localized distribution system congestion management. The future of demand response may move away from traditional utility control to automatic, pre-programmed triggers based on price thresholds.

Learn more
Two upcoming courses expand on PLMA’s demand response white paper to provide utility and regulatory staff and industry trade allies with a greater understanding of the evolution of demand response. Join subject matter experts from PLMA member organizations in Portland, Oregon, Sept. 26 or in San Francisco, California, Oct. 25.

Presentations will cover current technology and market conditions, utility case studies and more. Demand response will be compared to other load management strategies, and participants will discuss how to design a load management portfolio that serves your utility’s needs.

The training is open to all industry stakeholders, with significantly discounted rates to PLMA member organization staff.

Take steps to improve commercial customer irrigation efficiency

It is the height of irrigation season and everyone is struggling to keep their greenery green. While tips for water conservation often focus on residential lawns or agricultural crops, commercial landscaping offers significant opportunities to save water and reduce utility bills. For municipalities and multi-service utilities, helping these customers improve irrigation efficiency can yield benefits for both consumers and providers.

According to an article in Buildings, You are leaving WAPA.gov. a facility management trade publication, inefficient irrigation methods and systems can waste up to 50 percent of the water they consume. That quickly adds up to a painful water bill for your commercial customers and puts pressure on local water supplies and treatment systems. Share these tips to help facility managers at office parks, golf courses and other public green spaces get control of their irrigation practices.

Take care of your system
Failing to maintain irrigation systems may be the biggest factor leading to massive water waste.

Watering sidewalks is a big waste of water that can be prevented by periodically tuning up an irrigation system.

Watering sidewalks is a big waste of water that can be prevented by periodically tuning up an irrigation system.

One of the reasons for this neglect is that maintenance staffs often lack experience with irrigations systems. For example, when systems break down, they may attempt to make repairs with whatever equipment they can find, not understanding that every sprinkler waters differently. A replacement sprinkler head that does not work properly with the remaining original heads could affect the efficiency of the entire system.

Even working systems need a tuneup from time to time by someone who knows about irrigation. Something as simple as routine landscaping tasks can accidentally redirect a sprinkler head. Watering areas that don’t need it—like sidewalks and pavements near landscaping—can waste enormous amounts of water.

Choose your method
The critical question of which type of sprinkler technology to install–drip or overhead–is best answered in the system design phase. The two main types of irrigation systems each have their own set of pros and cons, many depending on the specific area to be watered.

The drip method of irrigation provides a steadier flow of water that goes directly into the soil, and can reduce water use by as much as 20 percent compared to an overhead sprinkler system. The down side of drip irrigation is that it is susceptible to breaking, and requires a higher quality of water. If you don’t have an in-house irrigation specialist, this may not be a good choice for your facility.

Overhead systems—more traditional sprinklers that spray water above the targeted plants—are likely to be less efficient with water use, but they require less maintenance. This method is suitable for larger lawn spaces, whereas a drip system might be more appropriate for localized shrubs and flowers.

Control, schedule watering
Setting a schedule for your system’s operation over time is vital to reducing water use and will have a big impact on conservation efforts.

The article states that a common mistake is turning on the irrigation system in the spring and keeping the same watering schedule until it is shut off for the winter. Plants generally need less water in May or October than they do in the middle of summer. Adjusting the schedule throughout watering season can not only reduce water waste, it can improve the look and health of the plants.

Big water savings can come from replacing a simple timer with a smart controller that determines watering schedules based on climate or soil moisture. However, educating staff members is critical to getting optimum results from a smart controller. Otherwise, your crew is likely to revert to a time-based schedule because it is easier to understand and gives them more control.

Try xeriscaping
Landscaping with native and drought-resistant plants is another proactive strategy for reducing water consumption. But unlike switching to a new type of sprinkler system, this change is relatively cheap and easy and offers a lot of flexibility.

Using native and drought-resistant plants can drastically reduce the amount of water required to maintain landscaping.

Using native and drought-resistant plants can drastically reduce the amount of water required to maintain landscaping.

The Environmental Protection Agency did a case study on a Texas shopping mall that coupled xeriscaping with changes to its irrigation system to reduce its water use by 60 percent. The Village at Stone Oak in San Antonio saved nearly 14 million gallons of water annually by converting around 50,000 square feet of turf grass to xeriscape and modifying almost 85,000 square feet of its irrigation system.

Utilities in the West have become increasingly aware that combining energy and water conservation efforts often improve the results of both. Feel free to share your ideas for taking customer programs out of silos and getting a bigger bang for your programming buck.

APPA honors WAPA customers for service, innovation

Congratulations to the four WAPA customers who were among 18 individuals and 10 utilities to receive awards at the American Public Power Association’s National Conference in Orlando, Fla., on June 20. Lincoln Electric System You are leaving WAPA.gov. (LES), Colorado Springs Utilities, You are leaving WAPA.gov. Fort Collins Utilities You are leaving WAPA.gov. and SMUD You are leaving WAPA.gov. earned recognition for their service to the public power industry and its member-customers

Continuing to excel
LES, a Nebraska municipal utility, earned the E.F. Scattergood System Achievement Award for outstanding accomplishments that enhance public power’s national prestige, improve customer service and demonstrate an earnest, coordinated effort on the part of the system.

In 2016, LES unveiled the state’s largest and first utility-scale solar array, Lincoln’s 5-megawatt (MW) community solar facility. Customers can invest in virtual solar panels, receiving credits on their bill. Improvements were also implemented to the utility’s rate structure to encourage energy efficiency and protect customers sensitive to bill fluctuation.

In the community, LES’s Energy Detective Kits teach students and their parents about saving energy, reducing water usage and lowering their household bills.

With a 99.99-percent reliability record, the utility continues to take strides to make sure its power remains dependable. Its mobile meter-reading project upgraded nearly all of the system’s 137,000 analog meters.

Supporting community
An established and evolving community safety program won the Community Service Award for Colorado Springs Utilities of Colorado. This award recognizes “good neighbor” activities that demonstrate commitment to the local community.

The community safety program, which has been a cornerstone of the municipal utility’s community involvement for 20 years, provides educational outreach in schools and at community events to audiences of all ages. Each year, almost 15,000 students, adults, contractors and first responders learn about gas and electric safety and about the safe and efficient use of utility services.

Recently, Colorado Springs Utilities revised and retargeted the education program to meet specific curriculum needs in schools and incorporate more messaging that is interactive and inquiry-based. “SafetyCircuit: Electric Safety and You” uses a live electric demonstrations board to show students the safe use of electricity indoors and outdoors, and how electricity affects our daily lives. An interactive live explosion demonstration is part of “Your Nose Knows! Natural Gas Safety & You,” a program teaching students about the properties and origins of natural gas and safety practices to prevent natural gas emergencies.

Increasing residential program participation
Fort Collins Utilities in Colorado and SMUD in California were among the four utilities to receive the Energy Innovator Award for utility programs or projects that demonstrate creative energy-efficiency measures or technologies. Eligible demonstrations can either improve customer service or increase the efficiency of utility operations. Judging criteria also includes transferability and takes into account project scope in relation to utility size.

The Efficiency Works-Neighborhood pilot program attempts to overcome barriers for customer project implementation, such as time and lack of money. The pilot is the next step for the Efficiency Works-Home program.

Fort Collins Utilities was honored for its successful Efficiency Works-Neighborhood You are leaving WAPA.gov. pilot program, which tested a streamlined process for home efficiency upgrades. The streamlined process made efficiency upgrades easy for customers by offering a choice of three packages—good, better and best—each custom-made for their homes. The packages provided upfront rebates, used standardized pricing, eliminated the need to get multiple contractor bids and ensured the quality of all completed work.

Over an 18-month period, the pilot program tripled the number of customers proceeding with energy-efficiency improvements and renewable systems installation. The upgrades lead to 50 percent greater electrical use reduction, 70 percent greater natural gas use reduction and 60 percent greater greenhouse gas savings per home.

Piloting cooling efficiency
SMUD received the Energy Innovator Award for its work with the hyper-efficient Climate Wizard air conditioner. You are leaving WAPA.gov. Manufactured in Australia, the Climate Wizard has the potential to use up to 90 percent less energy to cool the same space as an equivalent refrigerated system.

SMUD tested the Climate Wizard cooling system on two commercial customers to find out if the technology could be an effective peak-shaving measure.

Replacing conventional air conditioners with these indirect evaporative heat-exchange core systems could have a huge impact on SMUD’s peak cooling load during scorching Sacramento summer days. To evaluate the Climate Wizard’s performance, SMUD installed units with two industrial customers, a data center and a tool manufacturer You are leaving WAPA.gov..

The Tri-Tools production floor is not only hot from milling, turning and cutting metals, it is also humid from using water to cool materials during cutting. Because the Climate Wizard does not add moisture to the cooled air; it keeps employees more comfortable and improves the production process while saving the business energy and money.

The challenge for the data center Datacate is to maintain a consistently low temperature to keep servers and other equipment running 24/7. This pilot project, which will continue through 2017, has allowed the data center to operate more efficiently, add more capacity and lower operating costs.

The hallmarks of public power are dedication to community, commitment to innovation and constant striving to improve service. At WAPA, we already know our customers are leaders in the industry and we are excited to see that the industry recognizes them, too.

White paper compiles data on utility programs for low-income customers

Low-income households spend on average three times more of their income on energy bills You are leaving WAPA.gov. than other households, and easing the pain of higher bills during peak-load times of year is a continuous challenge for utilities.

This group of customers can be hard to reach, leading to a hit-or-miss track record for low-income energy-efficiency programs. But the benefits of successful programs stretch beyond energy and bill savings to include fewer shut-offs, healthier homes, less outdoor pollution and more local jobs. It is well worth the effort to design an effective program, and a new report from the American Council for an Energy Efficient Economy (ACEEE) can take some of the mystery out of doing it.

The baseline assessment of more than 70 utilities’ electric and natural gas programs chronicles total investments in these programs, energy savings impacts, customer participation and use of best practices. The study looked at the largest electric and natural gas utility serving each of the 51 largest metropolitan statistical areas.

ACEEE researchers found that low-income programs varied in terms of how deeply they address whole-home energy-efficiency needs and how accessible they were to customers. While many utilities design and administer impressive, effective low-income programs, many of those programs could be improved with best practice elements or increased resources.

The report also looks at best practices in implementation, including whether programs target specific households based on energy burden or other vulnerabilities and streamline enrollment for easier access. Partnering with the federal Weatherization Assistance Program (WAP) to leverage funds and reach more customers is another factor that impacts the effectiveness of a low-income program.

The study includes maps, data tables and new state-level information on low-income program requirements, cost-effectiveness rules and coordination with the WAP program. Utilities can use the data to see how their programs compare to those of similar utilities and to identify opportunities for adding best practice elements.

Read the entire ACEEE blog post for more information, and share your free copy of the report with state and local policymakers as well as other stakeholders. Also, if your utility has a program to help low-income customers, Energy Services Bulletin would like to know about your experiences.

Roseville Electric program takes home efficiency to next level

Even the most successful energy-efficiency program, like Roseville Electric Utility’s You are leaving WAPA.gov. high-performing BEST Homes partnership, needs a periodic renovation if it is to continue its success. To keep up with the changing times—and codes—the municipal utility recently unveiled its new Roseville Advanced Homes Program (RAHP).

Roseville Electric Utility's updated residential efficiency program is built around the principle that the best time to install high-efficiency features is in early construction.

RAHP is the next step in market evolution that Roseville began with BEST Homes, explained Program Manager Mark Riffey. “When we launched BEST Homes, Roseville builders weren’t installing solar and energy efficiency was nothing more than doing what was required,” he recalled. “But [California Building Standard] code has caught up with the program and will pass it soon.”

Title 24 You are leaving WAPA.gov. now requires new homes to be solar ready to meet requirements, making incentives for solar unnecessary. By 2020, the code will require all new homes to meet the net-zero energy standard.  RAHP encourages builders to meet that requirement proactively, building efficiency into homes before they even think about solar.

Starting on right foot
The program aims to get builders involved well in advance of submitting plans to the city, said Riffey. “The earlier they enter the conversation, the better chance of success.”

Any residential builder planning a development in Roseville may participate in RAHP by signing a prerequisite agreement confirming that their homes will include:

  • 75-percent high-efficacy lighting
  • HERS verification of Quality Insulation Installation
  • Electric vehicle charging station pre-wiring

These measures were chosen to provide a solid energy-efficiency foundation and because they are easy and relatively inexpensive to install early in construction. “The time to make sure a house is insulated correctly or to put in a dedicated breaker and conduit for an electric vehicle charger is when you are in the design phase or early in construction,” Riffy pointed out. “You can add those things later, but it is much more expensive.”

Once the prerequisites are in place, builders can earn incentives up to $3,500 per house for adding bonus measures such as whole-house fans, high-performance attics and LED lighting. Roseville is considering adding battery storage and triple-pane windows to RAHP in the future to move homes closer to the net-zero energy goal.

The completed home, with its tight shell and efficient systems and equipment, is then ready for a solar array. The homeowner can size the photovoltaic system for a load that has been reduced up front by best construction practices. “RAHP leads builders down the path to be aware of the measures that will get them to the 2020 requirement of zero-energy homes,” explained Riffey.

Or, to put it another way, it is going to take an integrated approach to meet the ambitious clean energy goals California has set for itself.

Working together
That focus on integration may be one of the biggest changes Roseville has made in its updated residential construction program. Where BEST Homes was a local effort guided by local stakeholders, RAHP was designed with the help of a third-party administrator to align with Pacific Gas and Electric Company’s (PG&E) California Advanced Home Program You are leaving WAPA.gov. (CAHP).

TRC, an engineering and construction management consultant, has administered CAHP for PG&E since 2011. “It was the best use of our resources,” observed Riffey. “TRC has spent years working with Title 24, and they can tell us measures that get the most bang for our buck.”

Coordinating with PG&E made sense, as well, because many Roseville residents are PG&E natural gas customers. After all, a well-insulated home is going to cut both heating and cooling costs. “Builders need to turn in only one set of papers for both programs,” said Riffey. “Anything that streamlines the program for the builder/customer improves its chance for success.”

Roseville Electric Utilities aims to succeed. Over its ten-year run, BEST Homes succeeded beyond expectations. A very high percentage of homes recently built in Roseville are solar ready, and California has made that requirement part of its building code. If RAHP enjoys the same kind of success, Roseville’s housing stock may set a zero-energy example for the whole state.

Report: Utilities can treat electric vehicles as demand response tools

Electric vehicles (EVs) are quickly becoming one of the largest flexible loads on the grid in certain parts of the United States. Bloomberg New Energy Finance projects EV electricity consumption to increase to approximately 33 terawatt-hours (TWh) annually by 2025, and 551 TWh by 2040.

While most industry analysts see EVs as a boon for utilities, load management risks are an issue. Managed charging—remotely controlling vehicle charging by turning it up, down or even off to correspond to grid conditions—could present utilities with an effective, new demand response opportunity.
