Are you planning a community solar program or looking for ways to make an existing program better? We think you will find every corner of this website useful; we've been assessing best practices and introducing innovations in this field for more than two and one-half years. But one of the lessons we have learned is that easy access to information counts. Community solar program designers and other stakeholders (inside and outside the utility) often find themselves facing a specific challenge—a burning question on a short fuse.

For that reason, we are thrilled announce the debut of a new set of easy-access web pages. We are referring to the Solutions pages, which you can find right at the top, on our Menu bar, above.

By now, a lot of readers are gone from this blog, off to explore the Solutions web pages. Yes! But if you are still reading, here’s a quick summary of what we offer and why.

What’s on the Solutions pages? Six sets of resources, each addressing a major challenge area for community solar program design process. These challenge areas come right out of our mission statement: First, we review the planning process itself, and the challenge of establishing a truly collaborative effort, which crosses utility-department boundaries. Second, we offer a brief introduction to high-value, strategic community solar design. Third, a discussion of procurement for products (including project development) and services. Some of those decisions come right away, as they define the community solar business model, and others come up as your utility team gets down to the details of program design and delivery.

Fourth, we take a look at target market research and market segmentation. At CSVP, we are happy to refer readers to other resources that build marketing intelligence and strategy; we zero in on target marketing and program customization as a fairly new and especially promising approach. We also echo the process-collaboration theme, as we suggest ways to get specific market research through internal collaboration.

Fifth, we provide resources in an area where the CSVP has broken new ground. That is, designing the program with solar plus storage or demand-response companion measures in mind. Even utilities that do not see solar-plus strategies on their doorstep should give this web page a look. CSVP offers a guide to using demand response (DR) measures to add integration value, and a separate guide to understanding storage choices on both sides of the meter. As utilities nationwide confront greater market-penetration of solar, the strategies we introduce can help, in terms of integration value, local-service risk management, and in terms of making a strong transition to succeeding in markets where lots of players offer lots of DER options to your customers.

Finally, an area of CSVP innovation, which again ties back to cross-departmental and customer-driven requirements of community solar. That is, assessing and increasing the net value of the offer, through a streamlined analytic approach we call GAP: Getting at Price. This approach identifies a strategic goal and then works back, to close the GAP between what the utility needs and what the customer wants in program pricing. In addition to an overview and exemplary generic models that show how GAP works, we offer a round-up of 12 current community-solar pricing models, for readers to review.

Our approach? There are a few unifying themes to all of the work that the CSVP has led.

Of course, it is all based on field experience. The individual firms represented on our team each have decades of experience working with utilities, and a few have been pioneers in the community solar field. In addition, we have relied on input from our Utility Forum, a loose network of six to ten utilities (public power, IOUs, and occasionally electric co-ops) to share their successes and frustrations. In most cases, they also reviewed our work products.

Another way CSVP define its approach is around the term practical. One interpretation: We are not shy about recommending the good works of others. That includes work from some of our colleagues who are also co-funded by the U.S. DOE SunShot Solar Market Pathways Program. We provide direct links to some of their works and also offer annotated, linked resource lists in most of our challenge areas. In those publications, you’ll find a fast path to resources that may be hard to find, but hit one or another nail right on the head.

CSVP’s focus has been on asking utilities to push beyond the ordinary—to use their cross-departmental expertise, technical insights and customer knowledge to create community solar programs that really are win-wins. CSVP is also known for promoting the concept of using community solar as a market-based laboratory. Where else will you find customers eager to work with you to try this new approach to distributed PV and indeed to distributed PV plus storage or DR, engaging the community in real solutions that are scaleable and replicable to address the needs of the 21st century grid?

We hope you will enjoy these resources. Please continue to engage with us, as we would love to see your comments or get back in touch with you. While each participating firm on our project offers its own, extensive expertise, this project is also keeping a core group of consultants on-board to expand our offerings, beginning with on-site trainings, facilitation, and specific expertise in each challenge area, to help you to initiate or improve your own high-value community solar program.

"If You Don't, Somebody Else Will"

By Erich Huffaker

As we examine the landscape for new utility “solar plus” projects, along the lines of community solar combined with demand response (DR) or storage, we realize that one of the more compelling reasons why utilities should pursue a this type of program is that a growing number of non-utility companies are already working in this market space. On the East and West Coasts and in some places in between, there is a burgeoning industry around integrated demand-side management, including DR, storage and distributed renewables. Innovative third-parties are giving electricity customers increasingly better tools to cut demand charges, modernize operations and reduce overall bills. For utilities that choose to watch from the sidelines, the fracture in the traditional utility-customer relationship drives deeper.

For example, GreenCharge Networks (GCN), with offices in Silicon Valley, New York, and San Diego, provides “intelligent energy storage” solutions-management services for onsite generation, energy management systems, DR, and storage. GCN installs integrated battery systems in large buildings and institutions nationwide. Recognizing that these systems can greatly expand the value of solar in mitigating utility demand charges, GCN is specifically targeting commercial solar sites. It is not adverse to utility partnerships, however—should the utility ask—as proven by recent work in collaboration with Duke Energy.

What about the arguments that storage is prohibitively expensive? Earlier this year, GCN secured financing to offer no-money-down battery systems to customers. And, GCN is not the only one providing this innovative financing model. Stem, a primary competitor to GCN, headquartered in Milbrae, CA, also offers a behind-the-meter demand-charge mitigation storage tools.

Companies are also making innovative software platforms to handle the increasingly evolving ecosystem of devices and hardware available for customer energy management. Geli’s hardware and software helps manage microgrid and EV-solar battery integration projects. The platform optimizes for complicated use-cases, involving multiple on-site assets, focusing on solar-plus-battery sites. Geli models the technical performance and financial impacts of installations, with market-specific information on how the system impacts utility tariffs and demand charges.

The takeaway is not that every utility should attempt to undertake innovative, complex integrated demand-side management projects on its own. Instead, it is that there is a growing customer appetite for more holistic energy management. In fact, this growing appetite is more important than any specific end-use solution. Once a customer has embarked upon this path with one service provider, that customer is unlikely to abandon that path completely and to start work with a whole new partner or partners. Continuity is valuable to these customers. That’s why the utility must show up now and join in, before it’s too late.

We’ve found that the utility has unique comparative advantages, which may be leveraged with the customer during this early-stage window of opportunity, irrespective of what other offers may be on the table by third parties. Utilities need to think clearly about what kind of a service packages they can provide to meet their customers’ needs. Often this will involve technical partners and initial pilot projects—in fact, projects that might include community solar, designed to include key stakeholders and technical partners. But utilities need to get serious about addressing this growing market, because if they don’t, somebody else will.

Erich Huffaker, a Project Specialist at Olivine, Inc. will be departing the CSVP Team this month as he pursues diverse professional interests and a penchant for travel. He recently coauthored the CSVP guide, Integrating Demand Response Into Community Solar Programs. We will miss him and look forward to his future dispatches.

The Flexible Grid Starts Here

When we began the Community Solar Value Project, we held a clear vision of shared-solar projects that would bring the utility and its customers together in a market-based demonstration of several DER strategies needed for an integrated and flexible grid. We envisioned tapping strategic solar siting and design plus DR and storage “companion measures”—orchestrated to help balance the load and increase the net value of local PV. Now, a year later, we’re almost there, except for a few challenges, including one in the guise of low-cost centralized solar.

Yes, it is hard to turn down a cheaper solar option. According to the Solar Energy Industries Association and GTM Research, solar costs fell last year to less than $1.50 per Watt for utility-scale fixed-tilt systems. If you were doing community solar primarily to deliver savings to subscribers, this might look like an answer. A number of utilities are now planning voluntary programs that tap big solar and package it kind of like wind-based green-power programs. Even community solar on the distribution grid is going to the urban fringe. In Minnesota, community solar developers have been co-locating 1-MW projects to reach economies of scale, with the state limiting developers to five co-located projects.

At the Community Solar Value Project (CSVP), we always recognized the benefit of scale. But we are focused on distribution-system projects, and preferably infill projects in the 500-kW to 2-MW range. Why? Well, one of our core assumptions is that distributed solar is here to stay. Whether or not the utility is involved, customers will pursue distributed solar. But if the utility were involved, the pairing of these large-commercial scale projects with DR and storage options (and in some cases, energy efficiency) represents what we call a “market-based laboratory” for field-testing many of the smart-grid and flexible-DER strategies that are currently stuck at the white-paper stage or in isolated pilot programs. As far as we know (and tell us if we’re wrong) no one has yet market-tested the economics of a distributed solar fleet strategy (achieving, say, 10 MW through a fleet of community-solar projects). Certainly there is little testing of distributed solar strategies that incorporate high-value companion measures. Sources like GTM Research and Rocky Mountain Institute and ICF International all have recently touted the distributed-energy future. And, for the most part, we believe them. But implementation in existing utility cultures, including engagement with and learning from “real” customers, is a project that needs to start now. The smart grid will not emerge fully armed, like Athena, from the head of Zeus. It will emerge from a trail of better and bigger attempts to get the thing right.

The CSVP recently started to work on an effort called “Filling the Pricing Gap,” to help utilities create and justify more competitive community-solar pricing for programs based (at least primarily) on local PV resources. You will see presentations and reports on our progress here in coming weeks. The folks at the Sacramento Municipal Utility District have been walking this road with us—or more accurately, they are usually in the lead, as they apply tremendous experience and in-house expertise to the challenge. One early example: they have taught us that a conventional “value of solar” argument is not such a practical solution for justifying near-term program design. For one thing it makes most utility guys’ hair stand on end. For another, it raises endless “what-if” questions about increasingly dynamic technical options, markets, and policies.
While others look for a VOS algorithm that would be, in effect a “theory of everything” for DER, we work to combine a relative few, fairly indisputable aspects of VOS analysis with targeted strategic arguments. This includes presenting what we call “realistic hypotheticals,” scenarios with ranges of numbers that are not intended to hit the value nail on the head, but which are nevertheless worth considering.

I use plural because we are addressing multiple internal stakeholders in the utility, all of whom have strong (and often conflicting) points of view. We are also addressing the utility’s most timely concern—that it needs to build and maintain strong customer relationships throughout these trying times. Watch our Library and Workshops pages for our reports from the field—where at least for the most part, we are keeping it local.

Innovation in the Holler

12/1/2015

by Spence Gerber, CSVP Team

Thanks to Solar Holler, a West Virginia-based non-profit solar development company for showing us how to prompt community engagement and leverage demand response (DR) in a completely new way. While this program model is not driven by a utility, it is utility-savvy, employing a similar DR strategy as the highly regarded program at Steele Waseca Electric Cooperative.

Two differences, though: First, it is focused on bringing solar benefits to public buildings, low-income housing, and churches, in a true spirit of “shared solar.” Second, it monetizes DR benefits at a regional market—in this case PJM. That may be a region-specific opportunity, but the overall program translates to almost any utility easily. Moreover, the big story here is that there is plenty of room for out-of-the-box thinking and innovation in the community solar space.

Let’s take the example of Solar Holler’s first project, where about 100 participants helped put 16-kW of PV on a Shepherdstown, WV, church. Anyone who has worked with a non-profit community based organization, whether it be a school, church, library or community center, is well aware of the challenges associated with meeting basic financial obligations—including the energy bill. Grant applications, fund drives, bake sales and passing the hat are efforts that are all too familiar to the good folks doing good things. All of this consumes an inordinate amount of effort and creates constant worry for the organization’s board and staff.

But Solar Holler has developed a model that takes a chunk of the ongoing expense of energy costs away from the organization, engages supporters, and provides collateral benefits to the community at-large. Based on estimated project costs, Solar Holler launched a crowd-funding effort for the church. Rather than ask for cash, participants that have electric water heat were asked to sign up for a free water heater controller. A small, nearby company that serves as a DR aggregator, called Mosaic Power, put in the devices, controls them together as a “virtual power plant,” and then participates in the PJM energy market. Mosaic gets paid for participation as a curtailment service provider.  The aggregator covers the cost for the equipment and installation of the water heater controller, as well as paying $100 per year to the each participant. Instead of receiving the annual payment directly, participants agree to apply the money toward payments on the loan for the solar installation. This plan has benefited the church and subsequently other facilities that serve low-income communities.

Solar Holler points out that the combination of solar-plus-DR reduces the use of fossil fuel in two ways. First, the solar project generates carbon-free energy, and second, the DR that Mosaic Power is selling to the grid most likely displaces fossil fuel resources that would otherwise be dispatched.  Beyond that, the solar and controller installations are providing real-life experience for local job training programs. According to the Dan Quitos, of Mosaic Power, the program has scaled up well so far and could support a larger effort, covering a large utility territory. The Solar Holler website includes detailed media coverage on all of its projects, including new work in the low-income housing sector.

To hear Dan tell the whole story, go to our webinar archive, under the Media tab. Solar Holler was featured on the CSVP November webinar, along with Grid Alternatives, another non-profit company that brings community solar to the low-income audience. In that case, projects often involve utilities directly. The staff at CSVP has identified these and other low-income community solar programs, in response to strong interest from the utilities nationwide. We invite you to learn more through this fact-sheet, and to let us know how you are tackling the challenge of increasing the availability of community solar options to people of all income levels and all housing types.
