Starting in 2020, all new residential homes in California must be built solar ready. On May 7, the California Energy Commission approved the 2019 Building Energy Code, which includes that provision.
This historic revision of building energy codes is expected to drive a large investment in residential rooftop solar and energy efficiency as California pursues its goal of getting 50 percent of its energy from renewables by 2030.
In addition to mandating rooftop solar, the code contains incentives for energy storage and requires new home construction to include advanced energy-efficiency measures. Using 2017 data, ClearView Energy Partners estimate that the mandate could require between 68 and 241 megawatts of annual distributed solar buildout.
Good for consumers, solar, storage industries
The commission stated that the new code is meant to save Californians a net $1.7 billion on energy bills all told, while advancing the state’s efforts to build-out renewable energy.
Following the commission’s decision, solar developers such as Sunrun, Vivint Solar and First Solar experienced a surge in stock prices, Bloomberg reported.
The updated codes also allow builders to install smaller solar systems if they integrate storage in a new home, adding another incentive to include energy storage. California has been a leader in incentivizing energy storage. In January, the California Public Utility Commission moved to allow multiple revenue streams for energy storage, such as spinning reserve services and frequency regulation.
Utilities question policy
The solar industry received a prior boost in January 2016, when the CPUC approved its net metering 2.0 rate design. The state’s investor-owned utilities asserted at the time that net metering distributed generation from electricity consumers shifted the costs for the system’s maintenance and infrastructure onto consumers who do not own distributed generation.
ClearView analysts pointed to the distributed solar mandate as a possible opening for utilities to argue that California regulators should reconsider the net metering reform proposal. According to the report ClearView published ahead of the CEC’s decision, utilities that opposed the new rate-design could claim that mandating distributed solar alters the policy landscape enough to warrant further review of the compensation levels paid to excess generation.

The United States Green Building Council recently recognized WAPA customer Fort Collins Utilities’ Administration Building with the Mountain West Region 2018 Colorado Green Building of the Year award.
Fort Collins Utilities was honored along with other award recipients May 3 at the Rocky Mountain Green Conference in Denver.
Sustainable architecture firm Stantec designed the Administrative Building to embody the community values demonstrated by Fort Collins energy and climate policies, and to document these high performance goals with Leadership in Energy and Environmental Design Version 4. Construction was completed in 2016, and accolades followed quickly. The building also earned an ENERGY STAR® score of 100 for operations in 2017.
The facility was the first in Colorado and fourth in the world to receive the Platinum designation under the latest version of the LEED standard. In addition to being one of the most energy-efficient buildings in the state, more than 95 percent of the construction waste was diverted from landfills. It features a 104-kilowatt solar system, and the city is currently reviewing designs to add a storage battery later this year.
Shoot for gold, hit platinum
The request for proposals called for the building to achieve a minimum of a LEED Gold rating under the new LEED v.4 standard, which has a more performance-based approach than previous versions. “The architecture went through a lot of iterations—in square footage, budget and so forth—but the specificity of the goals we set for the project in the RFP kept the design and construction team on track,” said John Phelan, Fort Collins Energy Services manager.
The city required the design and construction team to achieve all of the energy and atmosphere points to ensure ongoing performance, and challenged the team in other areas to achieve the certification. The choice to apply LEED v.4 presented the city with some challenges. For example, Phelan recalled that the materials category has new methodology and standards so the updated material data sheets were not always available. “That made it hard for the contracting team to get the necessary documentation,” he explained.
The integrated approach produced some clear triumphs as well. The design team focused on a well-insulated, tight envelope with extensive daylighting, resulting in a building with extraordinary light quality and views. “If you are not in a bathroom or closet, you can see the sky,” Phelan proudly stated.
Sustainability quest continues
The Utilities Administration Building is the first phase of an efficient new civic campus planned for Downtown Fort Collins. The master plan calls for the buildings clustered in a two-block area to be heated and cooled by a shared geothermal well field. Designers prepared the new building for that eventuality. It was designed to be able to connect the district heating system, promising an even better energy performance in the future.
Energy isn’t the only kind of performance the city is planning to measure. In an effort to understand the value of indoor environmental quality of this building, occupants have taken pre- and post-construction surveys on their comfort, satisfaction and how they feel about their work environment. Ultimately, annual utility bills are very small compared to the utility’s investment in its employees, explained Phelan. “You can’t lose sight of the fact that you are building for the people who work inside, doing the work that the community wants,” he said.
WAPA congratulates Fort Collins Utilities for another achievement in sustainability. The forward-thinking municipal utility has made great strides in lowering its carbon intensity, and never rests in pursuing more innovative solutions.
A new rooftop photovoltaic solar array is being installed every minute in the United States, with 4 million expected to be generating power by 2020. Knowledgeable building code professionals are needed to make sure these systems are installed correctly and safely. To help ensure quality inspections, the Interstate Renewable Energy Council has launched a new online interactive video solar training series for local code officials.
Taking the approach of the popular DIY series, This Old House, developers have created videos that are as entertaining as they are informative. Online viewers join IREC Training Specialist Joe Sarubbi to follow seasoned building and electrical inspectors through the finer points of five different solar inspections. Each video highlights a different type of system and technology, including:
- Microinverter systems
- DC-DC converter systems
- Tesla Powerwall energy storage systems
- Ground mounted AC-coupled systems with energy storage
- Commercial carport systems
Presented in an engaging, easy-to-watch video format, the training can be completed in just a handful of lunch-hour sessions and is aimed at new and experienced residential inspectors, as well as residential PV installers.
The videos incorporate the 2017 National Electrical Code and the most current international building, residential and fire codes. “The new PV Inspector Online Training course for code officials brings together a remarkable group of experienced PV system inspectors from across the country to present a wide variety of PV system types and technologies,” said Rebekah Hren, a member of the NEC’s Code Making Panel 4.
IREC developed the training in conjunction with the International Association of Electrical Inspectors and International Code Council with funding from the U.S. Department of Energy. Continuing Education Units are available from the IAEI, ICC and the North American Board of Certified Energy Practitioners.

Sometimes, you just don’t know what people want until you ask them, as the municipal utilities board of directors in Fremont, Nebraska, learned when they set out to diversify their municipal power portfolio.
City Administrator Brian Newton recalled that one of his first projects after joining the city staff three years ago was to work with the board of directors on a strategic plan for their power supply. At the time, the city of around 27,000 was powered mainly by coal and natural gas. “The board decided it would be a good idea to investigate adding other resources,” said Newton.
Consulting experts, customers
His initial reaction was that the customers would not be interested in solar energy. After all, Fremont residents enjoy a low residential rate of just 8 cents per kWh, and no one had installed a privately owned solar system.
So Newton took the prudent step of consulting experts before rushing headlong into a project. After scoring a Department of Energy Technical Assistance Grant, the city teamed up with the National Renewable Energy Laboratory and the Smart Electric Power Alliance to gauge customer interest in renewables and to explore financing options.
That was a smart move, because SEPA research has shown that a successful community solar project starts with knowing your audience. The survey SEPA conducted was an eye-opener for Newton. “More than 70 percent said they were interested in solar power, and some said they’d pay $10 more per month for it, which I doubted,” he said.
Just to make sure the survey results were on track, Newton held numerous public meetings to explain community solar to customers and get feedback from them. More than 500 people signed up to receive information about solar energy and many were adamant about joining the community affair. They not only wanted the solar power to be sold in Fremont, they also wanted it built by local developers, financed by local money and under community control.
Designed to sell
To make participation easy, Fremont put together a unique package of options. Customers can choose between purchasing panels, buying one or more solar energy shares and subscribing to a combination of panels and shares.
Solar subscriptions can cover up to 80 percent of residential customers’ annual kilowatt-hour consumption and 50 percent for commercial customers. One panel generates an average of 43 kWh monthly, while one solar energy share represents 150 kWh monthly. Customers who purchase panels are able to take advantage of the Federal Solar Investment Tax Credit, making participation even more attractive.
If the utility board of directors had any remaining doubts about customers’ interest in solar, those were laid to rest when the 1.5-megawatt solar farm sold out in seven weeks. Fremont promoted the project with customer meetings, emails and bill stuffers, the usual avenues for getting the word out. Newton noted that the 1.2-MW second phase of the solar farm is selling out by word of mouth alone.
Newton may have been surprised by customers’ eagerness to invest in renewables, but he told SEPA the rural community’s latent environmentalism shouldn’t be surprising. The community has always been firmly rooted to the land because agriculture is central to the local economy, he said. “Damaging the land or air isn’t an abstract idea. Fremonters can see the impact of environmental degradation on their livelihoods.”
Or, as one resident observed, Fremont’s support for solar power is not a surprise, as much as it is the natural progression of a long history of civic involvement in environmental stewardship.
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.
A small mountain town with many second-home owners, Estes Park installed two electric vehicle chargers in 2014 and offers its residents energy-efficiency programs and a renewable energy purchase program. Fort Collins, second-place winner of the Georgetown University Energy Prize, has been a global climate leader for nearly 20 years. It was at Fort Collins’ request that PRPA undertook the net-zero study. Longmont City Council recently adopted a goal to use 100 percent carbon-free electricity by 2030 and Loveland, an active contributor to the Rocky Mountain Utility Exchange, provides its customers with an extensive menu of energy-saving programs.
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.

Unpredictability has become the new normal for the power industry as Utility Dive’s fifth annual State of the Electric Utility Survey makes clear.
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.
You can download the 86-page survey report for free, or read a rundown of the top results with graphs. Utility Dive also hosted a sneak-peak webinar on the results at the end of January, which you can listen to for free.

Nothing says success like expansion, and the landmark agreement between the Navajo Tribal Utility Authority (NTUA) and Salt River Project (SRP) to expand the Kayenta Solar I facility has success written all over it.
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.
