Window replacement strictly for energy savings carries a big price tag that can be well out of range for many homeowners. Fortunately, there are several lower-cost options for reducing energy loss through windows that utility program managers might consider adding to their incentive offerings.
Reflecting on film
Window films help block against solar heat gain and protect against glare and ultraviolet exposure. According to the International Window Film Association, professionally installed window film can block 30-60 percent of all energy being lost through window glass throughout the heating and cooling seasons. IWFA also claims that window film in commercial buildings can deliver seven times the energy saving benefits per dollar spent compared with installing replacement windows.
DOE’s Energy Saver blog explains that reflective films work best in climates with long cooling seasons, because they also block the sun’s heat in the winter. Other factors that impact the effectiveness of window films include:
Size of window glazing area
Whether the window has interior insulation
Incentives for professional installation of window films could be a winner for utilities serving low-income areas in warmer climates. Homeowners and businesses in such regions might welcome an affordable alternative to window replacement. Check with your state energy office to see if it offers any tax incentives you can piggy-back on your program.
Drawing on curtains, shades
Carefully chosen window attachments can also save homeowners energy for less than the cost of window replacements. The Attachments Energy Rating Council is a good place to begin exploring options. The two-year-old organization is working with DOE to provide credible and accurate information about the energy performance of residential and commercial window attachment products.
For an overview of AERC’s work, download “Window Attachments: A Call to Action,” the Council’s updated brief. AERC is holding its annual meeting in Annapolis, Maryland, May 22 to 24.
Efficient Window Coverings, a guide supported by DOE and Lawrence Berkeley National Laboratory, is another valuable resource for evaluating different window products for energy efficiency. Website visitors will find a calculator to help them choose the best covering for their circumstances and a comparison chart to see how coverings stack up against each other. These functions can help utilities identify a range of options to appeal to different customer segments.
LED, or light-emitting diode, bulbs have become a major market player in recent years and can be expected to grow when new lighting efficiency standards come into effect in 2020. Utilities might be tempted to think that there is little of this “low-hanging fruit” left for residential efficiency programs to pluck. Before utility program planners sunset this portfolio mainstay, however, the American Council for an Energy-Efficient Economy suggests you take a closer look at the particulars of your program.
Well-designed lighting programs will likely continue to garner savings for utilities through 2019, but the outlook gets more complicated on January 1, 2020. For one thing, regional differences play a role in how lighting programs perform after the standards are raised. LED adoption varies from state to state and even within states. In most of WAPA’s territory, LEDs are between 20 and 30 percent of the light bulbs purchased. That leaves plenty of room for an effective program to grow the market.
Sales data indicates that lighting programs and retail support are strong drivers of LED adoption. Also, preliminary evidence from New York and Massachusetts indicate that LED adoption drops when programs end. So utilities would be premature to start scaling back their lighting programs—certainly where LED sales are low, and even in states like California where LEDs represent 40 percent of light bulb sales.
ACEEE identifies several program options that could continue the progress in lighting efficiency, even after the standards go into effect.
Underserved markets: Lighting programs can find additional savings by targeting rural, elderly and low-income market segments that have been slower to adopt LEDs.
Specialty lamps: LED versions of popular specialty lamp styles are now available, including decorative, candelabra, globe and reflector lamps. Yet these styles sell significantly fewer units than general-purpose LED lamps, suggesting that consumers need more education about the products.
High quality lamps: Programs should continue to promote high-performing ENERGY STAR-branded products, rather than “value” LED lamps that do not meet ENERGY STAR standards.
Controls: Dimming and occupancy controls offer significant additional savings opportunities. Lighting programs can help connect consumers to quality control solutions that are easy to install and operate.
While residential lighting efficiency programs still have plenty of savings left to tap, the technology’s increasing efficiency will eventually end their usefulness. It is not too soon for utilities to start considering the next opportunities for helping customers control and reduce their energy use.

In a state that many consider to be synonymous with energy innovation, the City of Colton Electric Utility must balance two competing challenges that will sound all too familiar to rural power providers across the nation. On one hand, San Bernardino County, California’s oldest electric utility has a fierce summer peak; on the other, a significant population of low-income customers struggles with each month’s electric bill. In true public power spirit, Colton Electric’s “Spring into Summer” campaign seeks to manage its peak by putting the needs of its ratepayers first.
The campaign, which runs from March 20 to June 20, encourages customers to upgrade certain items in their homes to energy-efficient products prior to the start of summer. The utility notifies customers about the program on their utility bills, Facebook, Instagram and the electric website. Flyers are also placed in city hall, the electric office and community centers.
Customers can take advantage of increased rebates for box fans, ceiling fans, swamp coolers, room air-conditioning units and air-conditioning system tune-ups, as well as whole-house systems. “We want to give all of our customers a chance to save,” explained Environmental Conservation Supervisor, Jessica Sutorus.
Utility programs for saving energy often focus on big measures like entire home cooling system replacement because those retrofits provide the best results, for both the customer and the power provider. However, low-income customers can rarely afford major home improvements, even though they need the savings as much as, or more than customers in other demographics.
Different demographic, different goals Even so, the “Spring into Summer” promotion is as much about customer outreach as it is about energy efficiency. “You have different expectations than when you are marketing to more affluent customers,” Sutorus acknowledged.
In that respect, “Spring into Summer” has been successful, increasing participation in the cooling rebate program by 40 customers annually, a 43 percent increase in participation. “Obviously those aren’t huge numbers, but we have only 16,000 residential customers and most of the participants are investing in the smaller-ticket items,” said Sutorus.
So while the savings to the customers may be meaningful, the program has not made much of a dent in Colton Electric’s summer load. Many Colton families pass their homes from generation to generation and don’t have the resources to make the kind of deep retrofits that are useful for load shaping. A lot of those houses are several decades old and still have the original windows, Sutorus noted. “Our residential programs are about serving the community,” she explained. “We have other plans to meet state goals for energy savings.”
Part of bigger picture Colton has recently begun to install smart thermostats throughout city facilities, and to replace old air-conditioning systems with Ice Bear high-efficiency cooling equipment. The measures are part of the Climate Action Plan the city adopted in 2015 to reduce greenhouse gas emissions.
This is where California’s progressive approach to climate change is helpful to the small “Inland Empire” city. The state’s Title 24 Building Standards Code requires developers to build housing that is highly efficient and solar- and electric vehicle-ready. This is good news for a city that is finally beginning to feel the effects of the economic recovery. “We are expecting new residential development, but industry is our fastest growing load,” Sutorus observed.
Colton Electric offers a menu of commercial customer rebates, including automated online energy monitoring analysis, lighting rebates and time-of-use rates. Support for commercial customers can help grow local industry and bring more jobs to the area. More jobs mean a stronger economy, and that, too, will be good for ratepayers.
The small towns of Nebraska boast a surprising number of large commercial and industrial customers, drawn in no small part by some of the lowest electricity rates in the country. Ensuring the economic vitality of these businesses—and their communities—is a duty that NMPP Energy and its member organizations take very seriously. “If the businesses are healthy, then the utilities are healthy and we all win,” said Bob Meade, former member services representative for Nebraska Municipal Power Pool and Municipal Energy Agency of Nebraska.
Meade, who retired in March, has a long history of working with municipal utilities in Colorado, Iowa, Nebraska and Wyoming to help large C&I customers keep their operating costs down. Low rates notwithstanding, Meade’s first contact with a business usually comes when one complains to the local municipal utility about high bills. “Either that, or they have an infrastructure request,” he said. “They want to upgrade their heating and cooling systems or outdated lighting.”
Meade frequently used the opportunity to do an energy audit on the facility. Businesses need the audit to apply for the Rural Energy for America Program from the Department of Agriculture to fund energy efficiency upgrades.
REAP grants provide up to 25 percent of total eligible project costs for improvements such as HVAC, lighting, refrigeration units and insulation. “Those are the most popular improvements for grocery and convenience stores in particular,” observed Meade. “Those upgrades can reduce a store’s energy charges by as much as 60 or 70 percent. The savings pay for the improvements, and in six or seven years the business sees that money go back into the bottom line.”
Bigger they are, more they save Large—as in multi-national—companies have even more to gain from efficiency upgrades. Becton Dickinson Inc., in Meade’s hometown of Holdrege, Nebraska, manufactures medical supplies such as insulin syringes to send all over the world. “Because they use robotics, the voltage and current levels have to be almost perfect,” said Meade. “Otherwise, they lose product.”
All products must be sterilized in an underground chamber, too, so a reliable, stable power supply is critical to operations. These circumstances make Becton Dickinson a good candidate for battery storage. NPPD is working with the company to evaluate the benefits and savings of installing a storage system.
Another, better known, large C&I customer is Frito-Lay in the town of Cozad. The snack food maker has a significant presence throughout the state due to excellent rail service and, of course, proximity to crops used as ingredients.
Meade recalled performing a detailed infrared inspection of an electrical room at the plant a few years ago, using one of WAPA’s IR cameras. “We identified more than 85 potential outages that could have caused downtime,” he noted. “That proactive inspection saved them a huge amount of lost work and product. It also convinced them to get their own camera and perform regular inspections.”
Saving electricity saves jobs Sometimes, good C&I customer service can help to retain jobs when a business changes hands. When Bass Pro Shop took over Cabela’s sporting goods stores in Nebraska, the city of Sidney expected to lose hundreds of jobs. However, Bass Pro Shop learned that Cabela’s had a much more sophisticated data collection program, so the company decided to relocate its data operations to the Cabela’s campus.
That plan hit a snag when Bass Pro Shop found low voltage in the selected building, and an engineering report failed to determine the cause. At the request of the Sidney public services director, Meade installed a power analyzer—again from WAPA—on the city’s transformer. The data the analyzer collects will help to correct the problem, and Bass Pro Shop may be able to offset some of Cabela’s layoffs with jobs in the data center.
Tools to build cooperation Diagnostic tools, borrowed from WAPA, were critical in helping NMPP utilities to resolve electricity issues for both Frito-Lays and Bass Pro Shop. “IR cameras and power analyzers are great for dealing with key accounts,” Meade pointed out. “You are able to walk in and do something proactive for your customers instead of waiting to react to their problems.”
What is even better, he added, is when a member utility or customer decides to buy the tool themselves. Prices for diagnostic technologies keep coming down, and once a customer sees how much they can save doing preventative maintenance, the case is made.
But first, you have to show them, said Meade. “We have a slogan at NMPP Energy, ‘Working together works,’ and it’s true,” he declared. “It works when we get our member utilities to work with their customers and it works when NMPP works with WAPA.”
Richard Eymann is stepping into Bob Meade’s shoes at the end of March to continue NMPP Energy’s tradition of outstanding member services. With 40 years of electrical and maintenance experience, Eymann will be providing the same high level of support and training NMPP Energy communities have come to expect. Members can contact Eymann at 402-474-4759.
Platte River Power Authority recently got the results of a study it commissioned on the relative costs of transitioning to net-zero carbon generation by 2030. The study found that the northern Colorado generation and transmission utility can deliver a net-zero carbon generation portfolio for a cost premium of only 8 percent over the lifetime of the planning horizon (2018–2050).
A story in RMI Outlet, the Rocky Mountain Institute blog, noted that researchers used relatively conservative assumptions for solar and wind costs, and did not consider demand-side efforts in their calculations. This is significant not only because the estimated difference in cost is so small, but also because it indicates the actual cost premium may be even lower than 8 percent.
History of commitment PRPA and its municipal utility owners—Estes Park, Fort Collins, Longmont and Loveland—have a long-standing commitment to clean energy and efficiency. The G&T contracts for approximately 198 megawatts of carbon-free resources from wind, hydropower and solar assets. In fall 2016, PRPA diversified its power production portfolio further by adding 30 MW of solar power at Rawhide Flats Solar.
Calculating total cost Technology company Siemens performed the study that is unique in showing a low cost for net-zero generation that incorporates transmission costs and balancing charges as well as fuel costs. RMI calls it proof that a net-zero path can achieve cost parity against coal even in coal country and that renewables can compete anywhere.
WAPA celebrates PRPA and its members for their initiative and for showing that public power utilities can lead the way to a low-carbon future.
The market for electric vehicles is growing quickly, and utilities can expect to play a central role in minimizing the potential grid impacts of this new load and increasing access to charging infrastructure. With that in mind, the Smart Electric Power Alliance has surveyed more than 480 utilities about their EV programs to create the industry’s first ever state-of-the-market report for EV programs.
Utilities and Electric Vehicles: Evolving to Unlock Grid Value couldn’t come at a better time, with many industry EV adoption forecasts being revised due to exponential growth. Bloomberg New Energy Finance predicts that electricity consumption will grow from a few terawatt-hours a year in 2017 to around 118 TWh by 2030. Many utilities may be unprepared for this sudden change in load growth. SEPA has collected information and tools in this report that can help utilities and their partners find a path forward.
The report includes:
A first-of-its-kind analytical framework for establishing the maturity of utility EV programs
Fourteen types of utility EV programs and activities categorized into early, intermediate and late stages
An overview of regulatory decisions regarding utility investments in EV charging infrastructure
Recommendations for strategic utility planning on EVs
Regulatory analysis and regional trends from over 70 EV-related regulatory dockets
A detailed analysis of the collected data revealed that 75 percent of utilities were in the earliest stages of EV program development. Time is not on the utilities’ side and they must begin now to work with peers and others in the industry to develop a robust EV strategy and identify ways to leverage EVs as a grid asset. Preparation today will equip power providers with the knowledge and technologies they need to unlock value in this new load.
You can download Utilities and Electric Vehicles: Evolving to Unlock Grid Value for free. SEPA members can gain access to the dataset by logging in to the SEPA EStore. The dataset includes the list of utilities included in the analysis, the total number of programs and activities identified by stage for each utility and the identified utility stage.
Electric vehicles potentially offer many benefits—as a distributed energy resource with the ability to modulate charge or even dispatch energy back into the grid—along with many unknowns for utilities. Use this report to introduce yourself to the promise and pitfalls of a load that could change our industry.
The survey of nearly 700 electric utilities in the U.S. and Canada indicated that their commitment to lower-carbon energy resources remains strong even as concern over market and policy uncertainty grows. Other top takeaways include:
Expectations of load growth – Since 2008, utilities have faced stagnant or declining demand for electricity, but this year, utility professionals see that trend changing.
Uncertainty, particularly in regard to federal regulation – Nearly 40 percent of utility professionals named uncertainty as their top concern about changing their power mix — almost twice the level of concern expressed about integrating distributed energy resources (DER) with utility systems.
Cybersecurity fears – For the second year running, participants placed cybersecurity at the top of their list of concerns, with about 81 percent rating it either important or very important.
Justifying emerging grid investments – Utilities see the need to invest in grid intelligence to manage electric vehicle (EV) charging infrastructure, DER, storage, analytics and cybersecurity. However, demonstrating the return on such high-tech investments to regulators, ratepayers and even their own organizations is complicated.
Traditional cost-of-service regulation falling from favor – Utilities are ready to adapt their business models to take advantage of new technologies and market opportunities. Around 80 percent indicated they either have or want a regulatory proceeding in their state focused on reforming utility business and revenue models.
Perhaps the most positive message to be taken from the results of the 2018 survey is how many utilities are willing to rethink the traditional business model in the face of changes in the industry. The report has a laundry list of other important insights on rate design, DER ownership, the increasing popularity of EVs and more. Whether you participated in the survey this year or not, it is sure to make for interesting reading.

Only the beginning The announcement of the expansion coincided with signing a long-term solar contract for the sale of firmed energy and environmental attributes from Kayenta II, as the project is called. SRP and NTUA also signed a memorandum of understanding (MOU) in which they committed to pursuing future renewable energy projects.
“The Kayenta I Solar Project has become the Navajo Nation’s showcase renewable energy project to demonstrate that the Navajo Nation is ready for large-scale renewable energy development and operation,” said NTUA General Manager Walter Haase.
SRP General Manager and CEO Mark Bonsall said that the agreement is an essential platform for the utility and the tribe to develop future projects. “The renewable energy credits from this project will also help SRP expand its renewable portfolio to further reduce carbon emissions,” noted Bonsall.
More renewables to come Under the MOU, SRP will provide technical support in developing interconnection facilities for large-scale renewable development within the Navajo Nation. The utility will also provide procurement and financing expertise related to the development and ownership of such projects. The agreement targets the development of at least 500 megawatts (MW) of renewable energy projects over the next five to 10 years within the Navajo Nation.
During the development of Kayenta I, SRP signed a two-year energy and environmental attribute contract. Once Kayenta II reaches commercial operation, the utility will add another year to the Kayenta I contract with options for further extensions resulting from the commitment to jointly pursue additional projects.
So far, development has focused on solar and wind resources, but the tribe is open to exploring other types of renewable generation. “We believe it is our responsibility to take the lead role in the development of renewable energy projects to promote economic development within the Navajo Nation,” said NTUA Spokeswoman Deenise Becenti.
Developing workforce, economy NTUA anticipates that Kayenta II will further prove the tribe’s ability to develop renewable energy projects and build on the economic gains of the first solar facility.
The 27.3-MW Kayenta Solar Project generates electricity to power an estimated 18,000 homes served by NTUA. At the height of construction, around 278 people worked on the project, 236 of whom were of Navajo descent.
The Navajo workforce was paid $5.2 million and received over 4,700 hours of specialized training in solar-utility construction for Kayenta I. The construction of Kayenta II will likely employ even more Navajo workers and is expected to produce similar salaries for the employees.
Tribe members have taken the skills they learned on the first Kayenta facility to other projects, added Becenti. “That trained workforce was able to find construction jobs at a solar farm in nearby Gallup, New Mexico,” she said.
The construction also generated $3,017,055 in taxes paid to the Navajo Nation. Overall, it is estimated that $15.6 million in economic activity occurred within the surrounding communities during construction.
Creating bright energy future The Navajo Nation considers Kayenta II to be the next step toward the tribe producing energy for its own use. The facility is expected to begin commercial operation in the May 2019.
There are no current plans to add storage to the project, but the technology is on the tribe’s radar for future opportunities. This is another area where the Navajo Nation may be able to leverage its partner’s expertise. Last year, SRP signed two power purchase agreements with NextEra Energy Resources, one for a 20-MW solar array with energy storage and a separate agreement for a 10-MW grid-scale battery. The utility also plans to work with NextEra to test the economic viability of using storage to integrate intermittent renewable resources on its grid.
The Navajo Nation appreciates SRP’s willingness to continue to work alongside NTUA, Haase stated. He looks forward to Kayenta II generating not only clean electricity, but more jobs and promising economic activity in the region, as well. “This partnership is all about progress,” said Haase.
The report draws on data from more than 1,000 Americans to yield 534 respondents with household incomes below $50,000. Members of the Low Income Energy Issues Forum, a diverse working group seeking innovations to make utility service more affordable, collaborated on the survey.
Even as the economy continues to grow stronger, many Americans still struggle to pay their utility bills. The number of low-income respondents who reported trouble paying their utility bills in 2017 increased 7 percent over the previous year. Also, 20 percent of respondents had applied for energy assistance.
Contributing to the general anxiety of trying to provide for their families, low-income customers experience uncertainty about the utility bill itself, the complexity of applying for energy assistance and confusion about how to control costs. Utilities seeking to improve service to this demographic might offer a range of voluntary options that customers could choose according to their lifestyle.
Consumers who are intensely focused on their daily budgets need more convenient choices. Simplifying tariffs, facilitating energy assistance through social service agencies and offering individualized “energy counseling” are among the services that could provide greater control to customers with limited financial means.
The findings also indicated that the low-income segment is far more engaged with their energy consumption than utilities believed. A majority of survey respondents have taken action on their own to save money on electric or heating bills. Consumers are eager for more information to save even more.
Perhaps the challenge is not consumer engagement but the entire construct of utility programs and policies to assist these customers. For example, a key metric used by advocates is “energy burden,” referring to the percentage of a household’s income required to pay utility bills. Yet, when asked, low-income customers understood “burden” somewhat differently; they focus more on eliminating uncertainty and getting help when they need it (situational awareness). This is an important distinction.
The 2017 survey points to the long struggle to improve service to low-income customers, beginning with utility program developers being willing to listen more carefully to customers themselves. We must be prepared to let go of the assumptions that undergird programs and assistance measures intended to help these customers, and develop offerings that more closely match their needs.
