    Addressing the Challenge of Distributed Energy Resource Growth and Keeping the Lights On; How the Electric Utility Industry is Coping with the Rise of Distributed Energy Resources

    January 2016 (West Monroe Partners)

    Executive Summary

    The rise of distributed energy resources (DERs) is an exciting and interesting opportunity for customers, and a challenge and opportunity for the utilities and the organizations that regulate them. DERs is a category of solutions that is inclusive of distributed generation sources like combined heat power (CHP), solar, and wind, as well as energy storage such as batteries. In this white paper, West Monroe Partners takes a comprehensive look at how consumers, utilities and regulators are approaching – or resisting – this energy evolution. This research examines the present and future state of DERs through multiple lenses: customer adoption and awareness; utilities’ adoption challenges and opportunities, and support and planning initiatives; and regulatory commissions’ actions, obstacles and perceptions.

    We found that while the presence of DERs among residential, commercial and industrial sites is still limited, customer interest is increasing and adoption is on the brink of booming in many states across the U.S. And though utilities and regulators alike acknowledge this potential shift, in many states they have yet to settle on clear and collaborative ways to prepare for it. Factors from technology availability and cost, to public policy drivers, to pivoting business models, are contributing to the obstacles slowing DER penetration across the U.S. These issues continue to impede the industry’s ability to smoothly accommodate new energy technologies and gain acceptance. By illuminating the gaps between customer needs, utility plans and regulators’ perceptions, it is evident that these audiences must form a more united front before meaningful change can truly occur in their state.


    The electric utility industry is accelerating toward a crossroads. Cost-averse and environmentally conscious customers are reducing their dependence on traditional utility generation and creating increased demand for distributed energy resources (DERs). If the market’s recent growth is any indication, DERs will become a more important part of the generation portfolio mix in the future.

    Between the U.S. federal government’s enactment of the Investment Tax Credit (ITC) almost a decade ago and launch of the SunShot Initiative in 2011, the cost of solar energy installations has plummeted more than 73 percent. This trend is aided by the U.S. Department of Energy’s decision to double down on its support for renewable energy research and development and materials manufacturing. While technology costs continue to decline and efficiencies rise, rest-of-system costs are coming down as well, making photovoltaic (PV) solar more affordable. Federal support, along with utility and state-sponsored financial incentives for purchases and leasing of rooftop solar PV systems, has accelerated adoption of DERs by residential, commercial, and institutional customers.

    In the last few years, the barriers to DER adoption have decreased significantly in many areas in the US. Solar generation is competitive with retail electricity prices in many parts of the country, and comparable to avoided transmission and distribution system upgrades in some utility jurisdictions. Cost reductions in DER implementation and interest in such systems apply across rooftop, utilityscale, and recently in community solar installations, providing opportunities for broad business and customer adoption. In 2014, a new solar project was installed every two-and-a-half minutes in the U.S.1

    As business and residential customers continue to seek more economical and sustainable energy solutions and utilities require cleaner energy power solutions to satisfy various regulatory requirements, distributed energy adoption does not appear to be slowing down anytime soon. General Electric predicts that annual distributed energy capacity additions will grow from 142 gigawatts (GW) worldwide in 2012 to 200 GW in 2020, an annual growth rate of more than four percent.2 Though this shift carries benefits for customers and the environment, it is forcing the utility industry and regulators to rethink the traditional utility business model and the sanctity of the utility franchise. As electricity generation becomes more decentralized and located closer to load, utilities are beginning to identify ways to maintain revenue and provide greater value to customers through alternative rate design, new utility business solutions, and creation of unregulated business enterprises.


    West Monroe Partners surveyed nearly 2,000 customers, 109 utility executives and managers in major markets across the country, and interviewed dozens of regulatory commission chairpersons, commissioners and senior staff. The goal of this research was to understand customer attitudes toward DER adoption, the broader impacts DERs will have on U.S. utility operations, and what both utilities and regulatory bodies are doing (or plan to do) to accommodate DERs from strategy, process, technology and system integration perspectives. Key findings from the study include:

    82% of utility executives say residential customers are adding DERs to their systems, more so than commercial and industrial users or the utility itself.

    80% of utilities report having DERs on their systems, but only 37% have services, systems or technologies in place to support them.

    49% of utility leaders feel DERs will reach a significant tipping point impacting operations when they account for 11 to 25 percent of their system generation; 75% of regulators feel the tipping point threshold is 1 to 10 percent.

    48% of residential customers are considering installing DERs for their homes in the next two years.

    59% of utility executives say their organizations plan to make no or minimal investments to support DERs on their systems, unless mandated to do so.

    The Impact of DERs

    Distributed energy resources present a new layer of complexity to utilities’ operations, while at the same time promising to inject new life into the traditional business model. Eighty percent of utilities in our survey reporting have DERs on their systems, but executives and regulators do not share a common vision when it comes to how regulations currently (or should) impact DER support and ownership. Today, three percent of customers have renewable energy sources serving their homes, and 48 percent are considering doing so in the next two years. Only one percent of customers are enrolled in distributed generation programs through their local utility. The rapid rise of DERs on utility systems is also creating difficulties for utilities to enroll customers and manage the interconnection process. Many utilities and regulatory commissions are looking at electronic enrollment and interconnection software to improve customer engagement and satisfaction.

    Seventy-nine percent of regulators feel that the current regulatory model allows and encourages utility ownership of DERs, compared to just over half (53%) of utility executives. This indicates a discrepancy between what utilities think they need in order to encourage and support DER ownership and implementation, and what regulators think utilities need. In certain markets, regulatory commissions think the regulatory paradigm supports DER deployment; however, they might lack the resources necessary to thoroughly investigate the regulatory changes needed to support utility investment and ownership.

    Despite the number of utilities that report having DERs on their systems, only 37 percent offer DER-specific support services, systems or technologies. In the same way that smart grids have enabled utilities to transform how they distribute and bill for electricity, DERs open the door for utilities to capitalize on new business opportunities, including backup generation, load balancing capabilities, differentiated pricing regimes, and solar marketplace services such as vendor identification, financing, and maintenance. Many utilities, however feel the cost of creating these services outweighs the returns: 59 percent of executives say their utility plans to make no or minimal investments to support DERs on their systems unless mandated by regulators.

    Early Reactions to the Rise of DERs

    The majority of utility executives harbor mixed feelings about how DERs will affect their business. Regardless of how executives feel, an uptick in adoption is inevitable. Two-thirds (66%) of executives feel DERs are both a threat and opportunity for their businesses, three percent feel they are only a threat, and nearly a third (31%) feel they present an opportunity. Understandably, many executives seem confused or feel it is too early to claim that DERs will or will not wreak havoc on their operations. As discussed later in this report, executives’ actions reveal that most utilities treat DERs primarily as a threat.

    Today, more than two-thirds (69%) of customers do not know if their utilities offer distributed generation enrollment, and 94 percent say their providers haven’t approached them about alternative energy options. This can lead to uncertainty and confusion about customer-sited DERs. As DER adoption grows, more customers will demand specific accommodations such as efficient distributed generation (DG) enrollment processes and management, and accessible DER diagnostics. Utilities that fail to provide a sufficient DER customer experience may suffer business and compliance consequences, and as a result, more oversight from regulators. Certain regulatory authorities (including the New York State Public Service Commission) are starting to require utilities to offer electronic DER enrollment to decrease customer effort and increase transparency around the DER interconnection process.

    Regulators are already modifying their requirements and compliance paradigm to support DER integration. Regulators cited a handful of concerns driving the proposed changes: Given the inherently polarizing nature of large-scale policy changes, utilities’ responses to regulatory modifications have been surprisingly positive. Two-thirds (67%) of regulators feel utilities have been responsive to regulatory changes, and half believe utilities are proactively adjusting their behaviors.

    Breaking Down DER Implementations

    The selection of available distributed energy options is expanding. Utility executives and regulators agree that solar resources stand to have the greatest impact on utility operations and revenue streams, more than other emerging resources such as electric vehicles and microgrids.

    There are several reasons for this, including solar’s proximity to load, ease of permitting and installation, and market awareness by non-utility and utility market participants relative to other renewable energy resources. Ninety percent of customers that have adopted renewable energy sources in their homes use solar systems, followed by wind turbines (7%) and hydropower systems (3%).

    Who’s Really Fueling DER Adoption…Accounting for Known Unknowns & Planning for the Future…Barriers to Accommodating DERs…Utilities Planned Charges to Account for DERs…How Regulators are Evolving to Support DERs…


    Greater adoption of distributed energy resources is more a question of “when” than “if.” Utilities and regulators agree that they must collaborate in order to address the challenges to DER investment, protect utility revenue streams, and support customers interest in DER. Residential customers’ DER adoption may not seem remarkable now in many parts of the U.S., but this audience is clearly positioned as a major driver of renewable energy’s future growth.

    On a positive note, utilities and regulatory commissions are not sitting idly by waiting for DER adoption to grow; they’re considering and implementing changes to support and accommodate such resources. For example, the New York State Public Service Commission is rethinking the traditional role and purpose of regulated utilities in its recently announced “Reforming the Energy Vision” initiative, a strategy intended to promote clean energy innovation and improve the utility customer experience.4 The California Public Utility Commission has also proposed a slate of innovative plans to accommodate DERs as part of its Distribution Resource Plan proceeding.5 The Massachusetts Department of Public Utilities has required utilities to prepare a business case for proposed grid modernization plans encompassing a wide-range of technologies, including DERs.6

    Other commissions across the country are actively addressing issues such as net metering, increasing or lifting the cap on net-metered loads, looking to capture the value of solar credits, and considering support for community solar systems. All of these initiatives, while rebranded or called something different, are an extension of the “utility of the future” and “utility 2.0” work started a decade ago. As the industry’s DER knowledge base grows and technologies proven, businesses, customers, and regulators will continue to look for ways to unlock value from these markets. Likewise, the promulgation of final rules implementing the U.S. Environmental Protection Agency’s Clean Power Plan for reducing carbon emissions from power generation is requiring a fresh look at how DERs might support CPP carbon reductions.

    Still, there’s more work to be done. Regulators need a better approach to understanding utilities’ challenges in order to create and adjust policies in ways that eliminate the barriers to DER support. This may start with more closely weighing the merits of utility versus non-utility DERs ownership. Specifically, regulators must focus less on rates and more on costs, and identify methods to help utilities address reliability and resiliency as generation occurs closer to load. They should also investigate new risk and revenue-sharing mechanisms to foster innovation, unlocking value from the utilities’ trove of real-time information and the potential of performance-based ratemaking.

    Part of the burden to evolve falls on utilities as well. Utility leaders need to start treating DERs as an opportunity more than a threat, concerning themselves as much with customer satisfaction as with revenue protection. From the utility provider perspective, it is not enough to have DERs on the grid. Given intensifying concerns about grid reliability, utilities can pursue new revenue streams by integrating DERs more closely into their systems and honing their distribution services. Utilities have a chance to expand their business model and strengthen customer relationships by delivering continuous DER support, and simplifying the DER application, integration, and support process.

    As utilities struggle to plan for and incorporate DERs into their existing resource plans, it is important to realize that a crop of alternative business models is emerging. There are several avenues for utility leaders to explore, from investing in third-party projects to managing community solar projects in lieu of disaggregated rooftop solar assets. Another route gaining traction throughout the sector is to invest in DERs via unregulated subsidiaries, as AES did through its acquisition of Main Street Power, or Duke Energy through its investment in REC Solar.

    The utility industry’s status quo has reached an inevitable turning point. If utilities and regulators make a concerted effort to confront these changes, everyone – including customers – can endure the growing pains and realize economic, social, and environmental benefits.
