The report identifies four primary drivers of resource adequacy risk in the Western United States: load growth uncertainties, extreme weather and climate change, delays in planned resource builds, and slow transmission expansion. To mitigate these risks, it proposes ten specific options for regulators categorized into three strategies: improving planning practices, widening the suite of resource adequacy solutions, and reforming utility business models.

The policy brief examines a pilot project in Mokoloki, Nigeria, where a privately owned solar minigrid shares existing distribution infrastructure with a utility to provide reliable power to 'undergrid' customers. It proposes that India, which faces similar challenges with high technical and commercial losses (up to 40%) and unreliable rural supply, could adopt this model to enhance last-mile service and financial viability for distribution companies.

The Mokoloki project demonstrates a new 'undergrid' business model where a private developer, Nayo Tropical Technologies, provides reliable electricity to a community within the territory of the Ibadan Electricity Distribution Company (IBEDC). The pilot has achieved 99.9 percent reliability, reduced energy costs for customers by ₦20/kWh, and decreased utility losses in the area by over 90 percent. The project supports local healthcare through 24/7 power for clinics and stimulates economic growth by powering small businesses and attracting new enterprises.

The document explores 'solar for coal swaps,' where third-party investors and developers purchase and retire a utility's coal assets in exchange for contracts to provide new solar power. This model aims to bypass utility inertia and high costs, particularly for municipal and cooperative utilities. The brief highlights that by 2025, 22.5 GW of such plants will be uneconomic compared to local solar. Case studies from New Mexico and Colorado, involving Kit Carson Cooperative, Holy Cross Energy, and Delta Montrose Electric Association, demonstrate how these swaps can reduce consumer rates and promote local economic development despite resistance from wholesale providers like Tri State Generation and Transmission Cooperative.

The briefing outlines the transformational shifts in the US energy landscape as of 2018, highlighting the move toward 100 percent clean energy goals by states and utilities. It identifies six critical areas requiring urgent attention: the revision of grid and resource planning to accommodate new technologies, the reform of utility business models, the integration of beneficial electrification for heating and cooling, the proper valuation of distributed energy resources (DERs), the assurance of equity for low- and moderate-income customers, and the financial management of uneconomic fossil fuel assets, particularly coal.

The document argues that the design of the process used to implement utility regulatory reforms is as critical as the technical and economic details of the reforms themselves. It identifies four stages of successful reform: initiation, communication of vision, conduction, and delivery of outcomes. The paper emphasizes the central role of utility regulators in driving these efforts and the necessity of a guiding vision to prevent reforms from becoming mired in adversarial debates.

The guide 'Navigating Utility Business Model Reform' aims to support industry actors in implementing utility business model reforms by outlining foundational elements of various reform options, posing key questions for applicability, and identifying illustrative experiences and policy implementation options.

The document argues that the energy transition provides opportunities for utilities to serve low-and moderate-income (LMI) customers through innovative models such as on-bill financing, community solar, and virtual power plants. It highlights the systemic inequities LMI customers face, including a median energy burden of 7.2% compared to 2.3% for others, and the historical siting of polluting power plants in these communities. The report details eight specific program models—ranging from utility-owned PV systems to integrated service bundles—and emphasizes the need for utilities to shift from simply informing customers to empowering them in decision-making processes. It concludes that these shifts align with a broader utility evolution from an expanded monopoly toward a transformed platform operator.

RMI defends its research on grid defection, asserting that while full disconnection from the utility may currently only be economical in Hawaii, the declining costs of distributed energy resources (DERs) create a risk of stranded utility assets. RMI critiques a Rochester Institute of Technology (RIT) study for focusing only on present-day costs and a limited set of DER options, arguing that the threat of future defection empowers customers and necessitates reforms in utility business models and retail pricing to achieve an integrated, cost-optimal grid.

The document outlines critical questions for regulators and stakeholders to assess utility regulatory models. For states using cost of service regulation, it prompts analysis of whether current financial structures incentivize innovation, environmental performance, and the role of third-party providers. For those considering performance regulation, it focuses on the definition of quantitative metrics, the consultation of stakeholders, the setting of ambitious targets, and the balance of financial incentives and penalties to drive the energy transition.

The document outlines eight key areas for electricity innovation in 2017, focusing heavily on the integration, valuation, and management of distributed energy resources (DERs). It highlights the shift toward technology-agnostic DER valuation, the potential for electric vehicles to serve as grid assets, and the need for alternative capital planning to displace traditional infrastructure. The text also addresses the necessity of evolving utility business models, establishing distribution system operators (DSOs), improving customer engagement, and expanding DER access to low- and moderate-income customers.

The National Energy Transition Strategy (NETS) for Saint Lucia identifies an optimal energy portfolio consisting of solar, wind, energy storage, energy efficiency, and existing diesel generation. This combination is projected to reduce diesel expenditures by 42% and carbon emissions by 40% by 2025. The report emphasizes that utility ownership generally leads to lower customer rates and that energy efficiency is the most cost-effective resource for minimizing system costs. While geothermal energy offers significant base-load potential, its viability depends on concessional financing and successful exploration. The strategy also highlights the need for regulatory reform, specifically decoupling utility revenues from sales to incentivize energy efficiency and avoiding 'rate shock' associated with certain independent power producer (IPP) arrangements.

The analysis finds that grid-connected solar-plus-battery systems will become the lowest-cost option for many customers within 10-15 years, potentially causing massive revenue losses for utilities. In the Northeast U.S. alone, potential residential and commercial kWh sales erosion by 2030 could reach 58 million MWh and 83 million MWh respectively. The report argues that eliminating net metering or adding fixed charges only delays this outcome. To avoid a future of stranded assets and high costs for non-adopters, the authors advocate for an 'integrated grid' featuring locational and temporal pricing, performance-based regulation, and the monetization of distributed energy resource (DER) values.

The analysis finds that grid-connected solar-plus-battery systems will rapidly become cost-effective, potentially leading to significant load defection that could undermine utility revenues and create stranded assets. The report argues that the electricity system is at a 'fork in the road,' where current regulatory and pricing models will either lead to fragmented grid defection or an integrated grid where distributed energy resources (DERs) provide value back to the system.

The document examines the shift from centralized to decentralized electricity structures through distributed energy resources, proposing three policy pathways: analyzing cost-benefit trade-offs, reforming utility business models and wholesale markets to increase competitiveness, and fostering technological innovation to accelerate the adoption of renewable resources.

The report outlines a new business model for Fort Collins Utilities that bundles energy efficiency and solar PV services into integrated packages. It recommends a hybrid approach using auto-enrollment (opt-out) for a basic package, financed via on-bill repayment mechanisms such as on-bill tariffs and energy service charges. RMI's analysis suggests the model could support 90% of residential building emissions reductions and generate net income for the utility. The document details a pilot project for 200–300 homes to test customer demand, financial viability, and operational infrastructure before a city-wide rollout.

The text suggests that the impending grid parity of solar-plus-battery systems presents utilities with an opportunity to adapt their business models and regulatory frameworks to create a lower-cost electricity system for customers and society.

The report identifies that current investor-owned utility and independent power producer models are ill-suited for the low-carbon transition, potentially raising renewable energy costs by up to 20%. It proposes a systemic evolution across five segments: generation (matching financing to risk profiles), transmission (improving renewable integration), market operation (valuing flexibility), distribution (adapting to distributed generation), and customer management (integrating demand response and electric vehicles). The document highlights the emergence of new financing models like YieldCos as a way to provide secure cash flows and lower costs.

The document examines Germany's 'Energiewende', a policy aimed at reducing CO2 emissions by 80 percent by 2050 and phasing out nuclear power. It highlights that while feed-in tariffs (FiT) increased residential electricity prices, they successfully reduced the cost of solar PV by more than 80 percent and wind by about half, benefiting global energy markets. The author notes that renewable growth has more than offset the reduction in nuclear power, though the transition requires new 'flexibility markets' to manage intermittency and new business models for utilities facing declining profits from conventional generation.

The report details a collaborative effort to accelerate the transition of Fort Collins, Colorado, toward a clean energy future. It assesses the current state of Fort Collins Utilities, proposes an accelerated timeline for meeting carbon and renewable goals, and suggests specific enablers such as a new 'FortZED tariff' and enhanced community engagement strategies to drive technology adoption while maintaining utility viability.
