Report, tools seek to boost building efficiency

Utilities have a vested interest in working with homeowners and businesses to accurately estimate and control energy costs. It is not only good for load management goals, it is also good for the local economy. A new report from Rocky Mountain Institute  You are leaving WAPA.gov. (RMI) and tools being developed by the National Renewable Energy Laboratory (NREL) can help utilities and cities move toward a more efficient building stock.

Changing real estate conversation
According to the online real estate platform Redfin, You are leaving WAPA.gov. energy bills can add as much as 40 percent to annual housing costs in some parts of the country. An MPG for Homes: Driving Visible Value for Home Energy Performance in Real Estate, the RMI report, makes the argument for incorporating energy use data into the total cost of homeownership calculations.

The authors emphasize, however, that making home energy use data more accessible is part of a greater vision. True market transformation will require a change in both homebuyer behavior and policies and approaches across several interconnected industries. The real estate, finance, home improvement and—yes—utility industry would all play a part and could all benefit in the long run from improving home performance metrics and making the data more transparent and accessible to homeowners.

RMI notes that the “green real estate” movement is already starting to catch on with online real estate portals featuring home energy scores on property listings. Partnerships between the Zillow Group You are leaving WAPA.gov. and UtilityScore, You are leaving WAPA.gov. Estately You are leaving WAPA.gov. and Clearly Energy and Redfin and Tendril You are leaving WAPA.gov. are aiming to make home energy scores a bigger consideration in buying decisions.

Recent home purchases drove 26 percent of home renovations in 2015, and preparation for resale led to 13 percent of renovations, according to Houzz and Home: Overview of Renovation. You are leaving WAPA.gov. Moreover, 67 percent of study respondents cited improving energy efficiency as an important reason for making a renovation. Clearly, renovation projects offer utilities an opportunity to promote energy-efficiency measures and programs to a receptive audience. Establishing relationships with housing professionals in the community could pay off for utility program managers in a big way.

Tools analyze home, infrastructure projects
Once you connect with customers who are interested in making energy-efficiency improvements, the next challenge is determining what upgrades will save them the most money and energy. The ResStock analysis tool from NREL provides detailed information on the technical and economic potential of residential energy-efficiency improvements and packages for 48 U.S. states.

By combining large data sources and statistical sampling with detailed building simulations, the program achieves unprecedented accuracy in modeling the diversity of the single-family housing stock. The ResStock software leverages DOE’s open-source building energy modeling platforms OpenStudio® You are leaving WAPA.gov.  and EnergyPlus You are leaving WAPA.gov. so you won’t need a supercomputer to run the program. Contact NREL to find out more.

On a larger scale, NREL’s Energy Systems Integration Facility is working on a demonstration project that is developing a buildings and district energy modeling tool, URBANopt. The demonstration integrates URBANopt with grid modeling software, OpenDSS, to analyze the projected dynamic energy consumption of a planned 382-acre mixed-use development. The Denver, Colorado, site includes corporate office space, retail space, multifamily dwellings, a hotel and parking and street lighting. This project will result in several tools that others can use to replicate this project across the country, including an enhanced version of URBANopt and a developer’s handbook.

Upper Great Plains taps South Sioux City for Administrator’s Award

WAPA Administrator Mark Gabriel will present WAPA’s prestigious Administrator’s Award to South Sioux City, Nebraska, You are leaving WAPA.gov. Oct. 18 at the Delta Hotels in South Sioux City.  The presentation is part of 2017 National Bioenergy Day, You are leaving WAPA.gov. an event that will be attended by local, state and federal officials and high-ranking industry representatives. Gabriel will also deliver the keynote address, “The Importance of Renewable Energy Diversification,” at Bioenergy Day. The event will also include a tour of the new Green Star Energy You are leaving WAPA.gov. gasifier power plant.

Despite its small size—a population just over 13,000—South Sioux City has consistently delivered innovation along with affordable, reliable power year after year, warranting the honor the award confers on a WAPA customer. But these accomplishments feel almost secondary to the vision that made them happen. South Sioux City is well known among its peers and many other WAPA customers for being exceptionally forward thinking and tenacious at finding and leveraging win-win partnerships.

Leading in renewables
South Sioux City is pursuing clean, low-carbon electricity with a unique mix of projects.

A 2.3-megawatt (MW) photovoltaic array is only the latest example of the town’s efforts to reduce its carbon footprint. The 21-acre solar park began operation in January and generates the equivalent of 5 percent of the city’s total electricity needs. South Sioux City also recently selected a firm to build 15 MW of new wind power and signed an agreement to begin receiving generation from it in 2018. Both the wind and the solar projects are public-private partnerships.

South Sioux City’s Solar Park: 2.3-megawatt array (1,200 panels) located on a 21-acre solar park south of the city, alongside C Avenue. The array generates enough energy to provide 5 percent of South Sioux City’s electrical needs.

In a region where agriculture and related businesses are the leading industries, biomass represents an energy resource that South Sioux City has captured through different projects. Three major food processing plants divert animal, grain and other wastes to an anaerobic digester that extracts methane from the stream and feeds it into the natural gas pipeline. The nearby Siouxland Ethanol Plant You are leaving WAPA.gov. displaces up to 9 percent of its natural gas needs for ethanol production with landfill gas from the LP Gill landfill.

The Scenic Park campground was the site of a pilot program in 2015, using a gasifier woody biomass system to generate 50 kilowatts of electricity from wood waste from storm damage. The unit was so successful that South Sioux City entered into an agreement with Green Star Energy to build a 3-MW gasifier. The new power plant will take city and industrial waste wood and dead and dying trees destined for the landfill and convert it into electricity.

Another potential project with Green Star Energy shows that South Sioux City has not lost sight of the tried-and-true renewable resources. The partners are seeking funding to build an innovative hydropower generator along the Missouri River that flows through the south end of the city. The run-of-river turbine design resembles a boat dock, would be safe for fish and aquatic animals and could produce enough electricity to save South Sioux City about $450 each day.

Conserve, reduce, manage
Energy innovation in South Sioux City is not limited to developing new resources. Planning and wise use are just as important to creating a cleaner, sustainable energy supply.

When peak demand needs to be curtailed, the city takes a two-pronged approach. First, a major industrial load voluntarily ramps down its demand by 11 percent to save not only its own energy costs but the energy costs for the city as a whole. On the residential side, the municipal utility has placed demand meters into service to control peak demand from air conditioner use. Both strategies have helped the community to contain electric costs.

South Sioux City has performed energy audits on all city buildings and facilities, and made improvements to systems such as lighting and heating and cooling, to save energy.

The municipal utility has performed energy audits on all city buildings and facilities to identify energy-saving opportunities. Improvements included adding variable speed drives, converting street and signal lighting to LED and installing LED office lighting. Energy-efficient heating and cooling measures and practices have also been implemented in city buildings.

To address the need for backup support and electric demand relief during peak times, the city is designing a 5-MW, state-of-the-art natural gas-powered generating station. Excess generation from the unit will be offered to the Southwest Power Pool You are leaving WAPA.gov. markets.

Practicing stewardship
South Sioux City was the first city in Nebraska to implement a paperless city council. In addition to reducing environmental impacts, the approach simplifies the archiving of council activities and makes it easier for the public to access more information. A voice-activated council chamber video recording system allows citizens to access live and archived meetings.

Tree health and sustainability are important to South Sioux City, which has qualified for the Arbor Day Foundation’s You are leaving WAPA.gov. Tree City USA designation for 25 years and earned the Growth Award for 10 years. For the past eight years, the city has planted one new tree for every 30 residents.

Residents enjoy the city’s two community gardens and the more than 200 fruit trees the city planted in 2014. The orchard is part of a facility designed in partnership with the University of Nebraska – Lincoln to provide storage and opportunities for youth outdoor learning activities. The new building is the first compressed laminated timber structure in Nebraska. Ash tree planks salvaged from emerald ash borer kill and milled by the Nebraska Forest Service side the building. The project received the 2017 Community Enhancement Award from the Arbor Day Foundation.

South Sioux City’s extensive trail network earned the first “Bicycle Friendly Community Award” in Nebraska in 2006, and hosts many rides, runs and other events throughout the year.

Quality of life is part of environmental health too, and South Sioux City actively promotes healthy lifestyles. The city’s extensive network of developed trails earned the first “Bicycle Friendly Community Award” in Nebraska in 2006. The trail system connects to 60 miles of trails in four cities and three states, and hosts many rides, runs and other events throughout the year.

Partners make it happen
Innovation doesn’t occur in a vacuum and partnership is as critical to South Sioux City’s efforts as vision is. City Administrator Lance Hedquist acknowledges that the city’s success with energy efficiency and renewable energy projects results from the support and trust of the mayor, council and staff who share his passion to make the city a great place to live and work.

South Sioux City’s collective approach to innovation, partnerships, governance and trust would be impressive in a city many times its size. In a small municipality, it deserves recognition: WAPA is proud to honor South Sioux City with the Administrator’s Award.

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.

The free event was held at WAPA’s Electric Power Training Center in Golden, Colorado, and drew strong attendance from every type of utility, especially in the West. As the workshop title stated, the agenda focused on the logistical aspects of building a community solar project and explored ways to make projects more successful. Speakers and participants discussed best practices for analyzing solar development opportunities, writing requests for proposals, engaging internal and external stakeholders, working with contractors and vendors and designing rates.

Customers share experience
Several WAPA customers were on hand to share their experiences with developing their own projects. Luis Reyes of Kit Carson Electric Cooperative You are leaving WAPA.gov. sat on a panel that focused on improving the procurement process. The Taos, New Mexico, utility launched its first community solar project in 2012 and has an ambitious initiative to install 35 megawatts of photovoltaics this year.

Participants throw ideas against the wall to see what sticks during table-top sessions on program design, procurement, rate design and marketing.

A panel on pricing challenges included John Phelan from Fort Collins Utilities You are leaving WAPA.gov. in northern Colorado. As a pioneer with Rocky Mountain Institute in clean energy and sustainability solutions, the city of Fort Collins has discovered that success brings a new set of challenges. For example, the utility is wrestling with how to design a rate that accommodates both a legacy community solar garden and a new array for qualified low-income customers.

Poudre Valley Rural Electric Cooperative You are leaving WAPA.gov. is currently developing a 6,000-panel community solar project with carve-outs for local nonprofit organizations and another for income-qualified customers. Making community solar available to customers who need the most help with utility bills was another topic that received a lot of attention. Utilities are experimenting with different business models for low-income projects, but most agree on the potential benefits: freeing up more money for other needs, bringing more certainty to monthly bills and raising energy awareness in a hard-to-reach group.

Attendees were all at different points on the learning curve with community solar. Representatives from the City of Fort Collins Utilities, Kit Carson Electric Cooperative and the city of Lamar, Colorado, shared their experiences during the free workshop.

SEPA report offers guidance on planning for distributed energy resources

As tempting as it may be for utilities to ignore the growth of distributed energy resources (DER), they must plan for integration of this form of generation. To help power providers develop a strategy to accommodate increasing DER penetration, Smart Electric Power Alliance You are leaving WAPA.gov. (SEPA) has published a two-volume report, Beyond the Meter: Planning the Distributed Energy Future.

Volume I: Emerging electric utility distribution planning practices for distributed energy resourcesThe utility industry is changing and many of the changes are being driven by consumers seeking new energy choices, technology advances leading to lower costs and better performance and new policies. Both utilities and their customers will have to work together to ensure grid reliability as distributed energy resource (DER) penetration increases. Engineering consultants Black and Veatch You are leaving WAPA.gov. collaborated with SEPA to provide a new strategy to become a proactive distribution planning utility.

Volume I: Emerging electric utility distribution planning practices for distributed energy resources outlines why traditional distribution system planning framework does not meet the needs of today’s grid. Five investor-owned and public power utilities shared their drive, progress and challenges when planning and proactively integrating distributed energy resources within their distribution system. The report covers:

  • Practical framework for distribution planning utilities
  • Insight from sector leaders on challenges and successes
  • Tools to better understand customer needs

Volume II: A case study of integrated DER planning by Sacramento Municipal Utility District Volume II: A case study of integrated DER planning by Sacramento Municipal Utility District details how SMUD used the findings of Volume I to forecast DER growth and plan for distribution challenges. Through the lens of SMUD, the report looks at the broader scenarios the electric utility industry can expect to encounter. The report covers:

  • Results of the new utility planning strategies
  • Risks and opportunities of new DER systems
  • More on the new distribution system planning framework

Beyond the Meter is free to download for both SEPA members and non-members.

IREC, partners push solar training for allied professions

Free webinar
June 15, 2017
12:00-1:30 PM MT

Half-day Forum
San Francisco, California
July 1, 2017

As solar installations continue to grow exponentially, there is an increasing need for other professions to know more about solar technologies. Firefighters, local code officials and electrical and building inspectors need a thorough understanding about solar technologies if the solar sector is to continue growing in a safe and sustainable way.

To meet this need, the Department of Energy SunShot Initiative provided funding to the Interstate Renewable Energy Council (IREC) to develop Solar Training and Education for Professionals You are leaving WAPA.gov. (STEP). Working with partners in related fields, IREC created a number of training resources for allied professionals whose jobs require some knowledge of solar technology.

IREC’s STEP partners are:

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.

Utilities and Electric Vehicles: The Case for Managed Charging

(Artwork by Smart Electric Power Association)

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.

Utilities and Electric Vehicles: The Case for Managed Charging, You are leaving WAPA.gov. by the Smart Electric Power Association (SEPA), offers a wide-lens overview of the managed charging ecosystem. This research report studies game-changing utility pilot programs for developing and testing managed charging approaches. Download the free report to learn about:

  • Examples of utility programs
  • Vehicle-grid integration and connected-car platform providers
  • Compatible electric vehicle supply equipment
  • Examples of automotive industry activities

Utilities have a central role to play as a nexus for stakeholders in the EV market, with their deep understanding of the grid and customers’ needs and interest. Power providers must act now to advocate for consumer-friendly features and programs, and to help shape relevant policies, regulations and standards. Utilities and Electric Vehicles: The Case for Managed Charging is an excellent resource for preparing for the future of EVs.

California utilities discuss concerns at UEF roundtable

An Energy Services Bulletin story last month looked at the results of a Utility Dive survey You are leaving WAPA.gov. that asked power providers what their biggest concerns were. This month, several California utilities—including many WAPA customers—gathered at the Utility Energy Forum You are leaving WAPA.gov. (UEF) Pre-Forum Roundtable to talk about the issues that kept them up at night.

Because of their potential as a revenue source and demand response tool, electric vehicles were a running topic at the UEF Pre-Forum Roundtable.

The UEF program committee asked utility and government representatives to weigh in on the topics they wanted to discuss in the exclusive session dedicated to those groups. Not surprisingly, the responses reflected California’s unique situation, even as they echoed the findings of the Utility Dive survey.

Energy storage
The question that was No. 1 in the minds of survey respondents was, “What is the value of energy storage for customers, utilities and the grid?” It is not hard to connect the dots between energy storage and concerns about distributed energy policy and aging grid infrastructure that ranked high in the Utility Dive survey. But in California, a combination of legislative and market forces have made energy storage specifically a relevant topic.

Most people automatically think about battery systems when they hear energy storage, and six utilities in the state have already installed and are experimenting with that technology. However, thermal storage—using available renewable electricity to heat water or make ice for later use in heating or cooling—is a proven technology in use at eight California utilities. Pacific Gas and Electric has the state’s only pumped storage project, which uses renewable energy to pump water to a higher-altitude reservoir where it is released to generate hydropower when needed.

Utilities and battery manufacturers still have much to learn about storage batteries, from funding and installation to operation and maintenance to best uses for the systems. Riverside Public Utilities You are leaving WAPA.gov. enlisted the University of California Riverside as You are leaving WAPA.gov. a research partner to discover more about solar-plus-storage capabilities. Imperial Irrigation District You are leaving WAPA.gov. installed 30 megawatts (MW) of storage last October. System operators find it valuable for balancing intermittent solar power during weekdays, but also note that it takes 220 tons of air conditioning to control battery temperatures. Maintaining constant battery temperature is crucial to extending the life of batteries. Tucson Electric Power (TEP) chose to lease 10 MW of storage from Next Era You are leaving WAPA.gov. and Eon You are leaving WAPA.gov. as a way of easing through the learning curve. The system supports 40 MW of solar and provides ancillary services for TEP.

So far, the business case for storage has yet to be made because utilities are still discovering the values associated with it. Also, each utility will have to learn how to maximize storage on its own system. Planning and rate design will play a critical role in unlocking the value of the technology. But utilities can’t afford to hang back, as big, energy-intensive businesses like data centers are already investigating going off-grid with their own solar-plus-storage systems. These customers may prove to be important partners for power providers seeking to meet storage mandates.

More to offer
Stagnant load growth appeared in the Top 10 Utility Dive survey results, a harbinger of reduced revenues utilities can expect from distributed generation and storage technologies. California utilities seem to be ahead of the curve in this respect, interested in exploring new business models to grow services and build relationships. Many roundtable participants have begun to create programs and services that offer customers more than kilowatts.

A number of industry surveys indicate that most consumers still rely on their power providers to help them sort out claims about electrical products and services. Utilities can leverage this trust to get customers to take a holistic approach to energy use, installing weatherization and efficient appliances and systems before moving on to renewables.

The City of Palo Alto Utilities You are leaving WAPA.gov. (CPAU), for example, offers comprehensive home audits and free concierge service that customers can call with any question about energy use. The service is just starting to take off as CPAU hones its message and outreach strategy. “Ongoing customer communication is critical, and not just for specific programs,” observed CPAU Key Account Manager Bryan Ward. “The issues are complex and education is tough, but the more customers understand, the more they can make good decisions for themselves.”

When the customer is ready to install a solar array, the utility has a vested interest in making sure the job is done right. Roseville Electric Utility’s Trusted Solar Advisor program has been highly successful in helping its customers make educated decisions about solar installations. The “Solar Guy,” Energy Program Technician David Dominguez, has even become something of a local celebrity. Roseville is considering expanding the program to other services, like electric vehicles and energy storage. The moral of Roseville’s story is that personalizing a program can take it to a whole new level.

EVs, rate design central to discussion
Of course, you can’t have a discussion about new utility services without the subject of electric vehicle charging stations coming up. Roundtable participants represented a number of different approaches to this service. Burbank Water and Power You are leaving WAPA.gov. installs level 1 (standard household) charger outlets on customers’ property and offers a rebate to customers to install a level 2 (240-volt) outlet.

CPAU facilitates permitting and filing for residential and commercial charger installation and for transformer upgrades. Multifamily units, nonprofits and schools are eligible for rebates for chargers, but high-tech businesses in CPAU’s territory didn’t need an incentive to install the technology. The important thing, most agreed, was that utilities need to be involved in pushing out EV chargers, both for the new revenue stream and to ensure effective deployment and implementation.

EVs and technologies like home automation—another behind-the-meter product utilities could offer—lend themselves to load shifting, especially in residential settings. To take full advantage of such demand response strategies, utilities will have to design rates that give customers a reason to participate. The Public Utility Commission of California You are leaving WAPA.gov. has called for robust time-of-use rates, which would present utilities with another customer education challenge. Power providers will also want to make sure that vendors of behind-the-meter services are giving consumers honest and accurate information and appropriate support.

Energy efficiency ain’t easy
The final roundtable issue was one that is relevant across the country, but again with special significance to California: What hurdles are you encountering integrating and managing more energy efficiency in your mix?

In addition to the state getting half of its electricity from green energy by 2030, California buildings must also increase energy efficiency by 50 percent. As any utility program manager can tell you, the more successful you are at reducing your customers’ energy use, the harder it is to find new savings. The overall trend toward higher efficiency standards for appliances and equipment, along with some of the toughest building codes in the U.S., is already making it more difficult to design effective efficiency programs.

Encouraging customers to make energy-efficiency improvements is further complicated by the fact that electricity rates may continue to rise anyway. Consumers don’t generally care about the intricacies of load resource balance or system optimization, issues that resist simple messaging. To make matters worse, third-party vendors rarely bother to explain to their customers how installing a measure will actually affect their home utility bills—if they, themselves, understand.

When the subject is energy efficiency, talk always circles back to flat and falling revenues, something affecting almost everyone on the panel. Sacramento Municipal Utility District You are leaving WAPA.gov. attributes a noticeable decline in sales to building codes. EV charging and electric water heating could help to make up some load, especially since most water heaters in the state are still gas units. But CPAU found few takers for a pilot program offering customers a generous rebate to install electric heat pump water heaters.

Change still only constant
There is still plenty of low-hanging efficiency fruit that utilities have not yet picked, though participants acknowledged that it may be getting more expensive to reach. The “free” electricity from a solar array is a lot more appealing to customers than elusive “savings” from an energy-efficient appliance. It is enough to make utilities wonder if the best days of energy-efficiency programs and incentives are behind them.

And yet, industry research shows a strong correlation between energy efficiency and customer satisfaction. Such programs give utilities a chance to interact with customers in a way they wouldn’t get to otherwise. Board members may continue to support a traditional program that does not contribute much to financial or operational goals because they see the public relations value of it. If utilities are going to phase out traditional energy-efficiency programs, they will need to find other ways keep customers engaged and happy.

The two hours scheduled for the UEF Pre-Forum Roundtable passed quickly and—spoiler alert—we did not resolve our most pressing issues. That is likely to take trial, error and perhaps an appetite for risk that is hard to square with our historic mission of reliability and affordability. But it did remind us that customer relationships must be viewed as part of the solution.

IREC releases energy storage guide for policymakers

Webinar April 26
1:30-2:45 p.m. MT

A new tool published by the Interstate Renewable Energy Council, Charging Ahead: An Energy Storage Guide for State Policymakers You are leaving WAPA.gov. provides regulators and other decision makers with specific guidance on key issues for policy consideration, including foundational policies for advanced energy storage—a new generation of technologies characterized by flexible operating capabilities and diverse applications.

The characteristics that make energy storage so valuable and attractive also make it challenging to address in policy and regulatory contexts.

Despite its game-changing potential to transform the electricity system, energy storage is vastly underutilized in the U.S. electricity sector. Its deployment remains hampered by the current features of regional, state and federal regulatory frameworks, traditional utility planning and decision-making paradigms, electricity markets and aspects of the technology itself.

To date, state policymakers and electric system stakeholders have largely navigated energy storage issues without the benefit of a roadmap to inform key regulatory and policy pathways for widespread deployment.

Charging Ahead aims to address that gap by providing an in-depth discussion of the most urgent actions to take in order to enable viable energy storage markets that effectively empower states to take advantage of the full suite of advanced energy storage capabilities. The guide identifies four foundational policy actions states should consider taking:

  1. Clarify how energy storage systems are classified to enable shared ownership and operation functions in restructured markets
  2. Require proactive consideration of energy storage in utility planning effort
  3. Create mechanisms to capture the full value stream of storage services
  4. Ensure fair, streamlined and cost-effective grid access for energy storage system

In addition to these foundational policies, the report provides background on energy storage applications, analyzes regulatory actions states are currently taking, and also puts some context around the valuation of energy storage. Read more.

A free webinar You are leaving WAPA.gov. on April 26 will look at how the report can equip regulators and other stakeholders to integrate energy storage technologies onto the grid. Recommended state policy actions to address energy storage barriers will also be discussed.
