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.

CIPCO builds Iowa’s largest utility-scale solar project

In Iowa, where renewable energy is often synonymous with wind, one generation-and-transmission (G&T) cooperative is making a big investment in utility-scale solar generation. Over the last year, Central Iowa Power Cooperative You are leaving WAPA.gov. (CIPCO) built the state’s largest photovoltaic (PV) project across five sites in its service delivery territory.

The member cooperatives involved in the project are Clarke Electric Cooperative, You are leaving WAPA.gov.Consumers Energy, You are leaving WAPA.gov. Eastern Iowa Light & Power Cooperative, You are leaving WAPA.gov. East-Central Iowa REC You are leaving WAPA.gov. and Pella Cooperative Electric. You are leaving WAPA.gov. The 5.5-megawatt (MW) project will provide electricity to all CIPCO members of all income levels. “It is our mission as a cooperative to support all our members equally,” noted Communications and Public Affairs Manager Kerry Koonce. “Choosing the utility-scale model for the project rather than community solar accomplishes that.”

Becoming solar leader
In late 2015, CIPCO issued a request for proposals (RFP) for the development of the first of what is intended to be a two-phase utility-scale solar project.

Several of CIPCO’s 13 members showed interest in hosting a site. Then followed the hard work of determining which sites would be appropriate. “Some potential sites didn’t have sufficient resources, others had leasing issues,” recalled Koonce. “It is so important to make sure to get the correct layout, especially with a first-time project.”

CIPCO had help from the National Renewables Cooperative You are leaving WAPA.gov. (NRCO), a trade group formed by cooperatives to facilitate the development and deployment of renewable energy resources. NRCO managed the RFP process and supplied engineering expertise for the project. CIPCO has used NRCO resources in the past to review wind-purchase contracts as well.

To install the arrays, CIPCO selected Azimuth Energy LLC You are leaving WAPA.gov. of St. Louis, Missouri, an engineering, construction and development-support service company for renewable energy and energy efficient projects. The design of the ground-mounted arrays included features like fixed-axis racking and transformerless string inverters to reduce installation cost, improve performance and simplify maintenance. The projects were completed on schedule by the end of 2016.

Sun keeps rising
The new solar generation is part of a portfolio that includes 199 MW of wind power, 14 MW of WAPA hydropower and 1.6 MW of waste-to-energy generation. In all, CIPCO gets nearly 60 percent of its power supply from low-carbon resources. Koonce observed that clean energy has always been important to CIPCO’s members and with the decline in solar panel prices, the time was right to add solar to the mix.

According to Koonce, the solar site will eventually pay for itself in the energy it produces, although the exact payback period is not known. The $9 million cost of all five solar sites, spread over 20 years to take advantage of some federal solar tax credits, is significantly less than the cost of building a new coal-fired plant, she added.

CIPCO’s overall resource plan focuses on natural gas, wind and more solar, with a second phase of solar development planned for this year. Battery storage is not part of the conversation at this point, Koonce noted, because the cost of storage systems is still very high compared to CIPCO’s stable rates. For now, “Our members won’t be seeing an increase due to adding solar,” Koonce says. “The resource is very cost effective for us.”

But members can be sure that CIPCO will be watching battery storage and other new technologies, as the G&T continues to build its diverse, affordable and environmentally friendly power supply.

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.

Still time to register for free community solar workshop

June 7-8
Golden, Colorado

Community Solar Procurements, Programs and Pricing, a free regional workshop for utilities, is filling up fast but there is still room for a few more attendees.

Community solar projects are a successful business model where multiple customers share in a large solar array, paid for through individual utility bills. It has seen such rapid growth across the country that it has become almost commonplace. Despite that fact, utilities are still learning about every aspect of this resource. It is important to get your project off on the right foot or correct missteps before they mushroom.

WAPA’s Renewable Resources Program has teamed up with the Community Solar Value Program You are leaving WAPA.gov. (CSVP) to make it affordable for power providers to share best practices in developing this type of generation. There is no registration fee for this event; attendees need only pay for their travel to Golden, Colorado. “Helping our preference utility customers learn about community solar and other renewable technologies, as well as tools and resources for smooth integration are a core part of WAPA’s Renewable Resource Program,” explained Randy Manion, WAPA Renewable Resources program manager.

The agenda You are leaving WAPA.gov. draws from an investigation conducted by CSVP into utilities’ best practices and innovations in community solar. From design to procurement to marketing, participants will hear from expert speakers and utility peers who will share their experiences. Presentations by WAPA customers include Kit Carson Electric Cooperative You are leaving WAPA.gov. on requests for proposals and Sacramento Municipal Utility District You are leaving WAPA.gov. on integrating community solar with distributed systems.

WAPA’s Electric Power Training Center (EPTC) in Golden, Colorado, is hosting the event. The workshop will begin at 3:00 p.m. on Wednesday, June 7, with a “lightning round” of community solar best-practice presentations and a tour of EPTC’s grid simulator, followed by a networking reception. On Thursday, June 8, the workshop will convene from 8 a.m. to 5 p.m., with breaks and a networking lunch provided by Extensible Energy LLC included.

Registration is free, but required. Participants only cover travel and hotel costs and incidentals.

Don’t miss this opportunity to explore this promising strategy for incorporating solar power into your resource mix.

We hope you will save the date and plan to join your colleagues—and your WAPA Energy Services representatives—for three days of learning, networking and professional development.

Next year’s event may even sweeten the deal for busy utility employees with a limited travel budget. The UEF planning committee is considering offering training opportunities in conjunction with the annual Forum as a separate event. The training would take place on Tuesday afternoon before the Forum begins on Wednesday and would be open to Forum attendees for an additional fee.

Please take a moment to complete a brief survey You are leaving WAPA.gov. to tell the committee if this is of interest to you. If there is enough interest, there will be a pilot program at the 2018 event.

Community solar project expands VEA solar portfolio

A leader in solar water heating programs is now adding 15 megawatts of photovoltaic energy to its electricity supply. Valley Electric Association You are leaving WAPA.gov. (VEA) has constructed a 54,000-panel solar plant on 80 acres of desert near the California-Nevada border and plans to sell the power to members at a lower price than their current electric rates.

The community solar project located just north of Pahrump, Nevada, VEA’s home town, produces enough electricity to power 2,500 homes. The goal of the plant, according to VEA CEO Thomas H. Husted, is to give members more choice of energy resources.

Members were showing interest in solar but weren’t able to install their own arrays, said Kristin Mettke, VEA executive vice president of Engineering and Compliance. “Also, there aren’t many large solar contracting companies in our service area,” she said. “This project was a good way to offer solar to our members at an economy of scale.”

VEA plans to turn the project into a subscription program. For now, however, the clean electricity is helping the co-op meet its growing demand with a low-cost resource.

Partnering to protect wildlife
Even projects intended to save money—and the environment—come with complications, however, and the community solar project was no different. The chosen site was home to sensitive plants and the threatened Mojave Desert tortoise, so accommodations had to be made.

VEA and solar contractor Bombard Renewable Energy worked with the U.S. Fish and Wildlife Service to develop a habitat conservation plan to minimize the disturbing effects of construction “It gave us the opportunity to try different approaches,” observed Mettke.

Measures included relocating tortoises to a temporary habitat before beginning construction and installing temporary fencing and tortoise-proof access gates to prevent them from returning. The completed project had a permanent security fence with tortoise access points to allow the animals to reenter the site.

To provide habitat for the tortoises, the native vegetation was mowed, crushed or trimmed, rather than removed. Increasing the height and spacing of the PV panels and installing them to follow the natural undulations of the land will also allow the vegetation to recover more quickly after construction.

Solar water heater pioneer
The community solar project continues VEA’s tradition of using solar solutions to provide members with affordable power. In 2009, the co-op launched what was, at the time, the largest solar hot water program in the country.

For around $30 per month paid on-bill, members can install a Rheem solar water heating system. This highly efficient technology uses the sun’s heat to reduce the need for conventional hot water heating by as much as two-thirds. Members can save about $250 to $540 in annually and enjoy 50-100 percent greater hot water capacity.

With 835 systems installed to date, the program avoids more than 3,000 pounds of carbon dioxide emissions annually while building local workforce skills. VEA estimates that solar water heating will save members about $34 million over the next 20 years by decreasing peak power demands and delaying future upgrades to capital infrastructure.

Planning next steps
Now that the solar project is completed, VEA has begun to talk with battery vendors about adding backup storage. “A battery system would complement solar power and help with resource adequacy and shoulder times,” said Mettke.

The co-op is also developing a subscription program that would allow members to lease panels. The program would be introduced through VEA Ambassadors, members who take an active interest in the day-to-day operations of their utility and who offer feedback on VEA initiatives, activities and policies from a consumer perspective. The Ambassadors were instrumental in rolling out VEA’s solar hot water program in 2009.

The solar hot water program and now the utility-scale community solar project have given VEA valuable hands-on experience developing and integrating renewable generation. That expertise may someday come in handy for developing cost-effective clean energy projects for California. The co-op became the first out-of-state utility to join the California Independent System Operator balancing authority in 2013, a move that could present such opportunities to VEA. It would be a challenge, but if it strengthens member relations and builds local workforce skills, Valley Electric Association is up to it.

Utility Dive lists Top 10 transformative trends: What do you think?

Transformation could be the most overused word in the electric utility industry these days. Big data, energy storage, the internet of things and electric vehicles are just a few of the technologies we are being told will change the way we do business forever.

But what utility professionals see on the ground may be quite different, both from what we hear and from what other utilities are dealing with. The trends that are actually affecting your utility depend on what part of the country you serve, what your customer base looks like and whether you are an investor-owned or public power utility.

To get a sense of where the utility industry is headed, the online magazine Utility Dive You are leaving WAPA.gov. recently identified 10 trends that seem destined to shape our near future:

10. Coal power in decline – Since 2009, 25 gigawatts (GW) of coal capacity has retired in the U.S., and another 25 GW of retirements are planned by 2022. However, the Environmental Protection Agency still expects coal to be a major fuel source for electricity generation through 2030.

9. Natural gas is growing fast – As market conditions and regulations push older coal generators into retirement, utilities are increasingly looking to gas plants to add reliable capacity quickly. Analysts still expect it to grow steadily over the coming decade and then switch to retirement between 2020 and 2030, a trend that could come sooner if natural gas prices rise from their historic lows.

8. Renewables reaching grid parity – Once dismissed as too expensive to be competitive, wind and solar—especially utility-scale—are reaching grid parity and often pricing out more traditional generation resources. In fact, the Department of Energy estimates that wind could be the nation’s single greatest source of energy by 2050, comprising up to 35 percent of the fuel mix.

7. Utilities face growing load defection – With the rapid proliferation of rooftop solar, some customers are bypassing their local utility for their electricity needs, especially in a few markets such as Hawaii and California. Customers combining load management strategies with rooftop solar installations could purchase less power from their utility, and may even cut the cord altogether.

6. Utilities getting in on the solar game – A number of utilities are responding to load defection and consumer demand for clean energy by expanding into the solar industry, both in the utility-scale and rooftop markets. Community shared solar, which allows customers without suitable rooftops for solar to buy a few modules on a larger array, grew exponentially between 2014 and 2016.

5. Debates over rate design reforms and value of distributed energy resources (DERs) are heating up – Altering rate designs to properly value distributed resources is a trend that has largely grown out of retail net metering. This pays utility customers with solar the retail rate for the electricity they send back to the grid.

4. Utilities are modernizing the grid – Adding new utility-scale and distributed renewable capacity has increased the need for utilities to upgrade and modernize their transmission and distribution grids. Many of the regulatory initiatives underway to help determine the value of DERs also order their state’s utilities to prepare their distribution grids for increased penetrations of distributed resources.

3. Utilities buying into storage – Few technologies hold as much promise as energy storage for utilities looking to optimize their distribution grids and integrate more renewables. While the price for battery storage is still too high to make projects economical in regions with relatively inexpensive electricity, costs are coming down quickly.

2. Utilities becoming more customer-centric – Power companies used to think of their consumers simply as ratepayers, or even just “load,” but new home energy technologies and shifting customer expectations are pushing them to focus on individual consumers. Increasingly, utilities are seeing it in their best interests to market themselves to customers as “trusted energy advisors” of sorts.

1. Utility business models are changing – The common thread running through these trends is that they all are changing the way electric utilities have traditionally done business. Where utilities were once regulated monopolies, the growth of distributed resources is forcing them to rethink their business models. California and New York have captured most of the headlines for redefining the utilities’ role on the distribution grid, but other states have initiated their own dockets to transform business models.

It is likely that your utility has had to think about at least a few of these issues and may be grappling with more of them before long. Energy Services is here to help our customers manage these challenges and more. Contact your Energy Services representative to discuss how to turn transformation into your greatest opportunity.

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.
