The document examines the vulnerability of the US gas-fired power plant fleet to extreme winter and summer weather, noting that gas plants are the primary source of generation failures during major storms. It argues that current resource adequacy metrics overvalue gas reliability and recommends transitioning to probabilistic modeling, increasing transparency, and prioritizing renewables, storage, and demand-side solutions to ensure a resilient power grid.

In 2024, WRI supported over 150 U.S. cities and counties in accelerating clean energy deployment and helped over 60 cities claim more than $12 million in tax credits via the Inflation Reduction Act's elective pay mechanism. The organization advanced next-generation geothermal technologies, launched a database of 50 community benefits frameworks for transmission projects, and supported the deployment of electric school buses (ESBs) through initiatives like the RVXDS project in California. WRI also focused on reforming power markets and grids, providing technical assistance to the PJM Cities and Communities Coalition and researching interregional transmission procurement.

The document analyzes Gogoro's transition from a startup to a global provider of light EV battery swapping. It attributes the company's success to three system-level innovations: the creation of a swappable battery standard adopted by multiple manufacturers, the implementation of new business models such as battery-as-a-service and virtual power plants, and the development of a physical 'swap-and-go' platform. The case study highlights Gogoro's role as a catalyst in Taiwan, where its batteries power 90 percent of electric scooters, and its strategic expansion into markets like India, South Korea, and the Philippines.

Virtual power plants (VPPs) aggregate distributed energy resources like batteries and electric vehicles to provide grid benefits. In the United States, VPPs could reduce peak demand by 60 GW by 2030 and 200 GW by 2050, while potentially reducing annual power sector expenditures by $17 billion by 2030. They support decarbonization by reducing reliance on polluting peaker plants and enable economy-wide electrification by providing revenue streams and avoiding grid bottlenecks.

The document argues that demand-side flexibility (DSF) is essential for integrating intermittent renewables and managing the electrification of transport, buildings, and industry. It highlights that while large industrial users have traditionally provided flexibility, residential and small business consumers have significant untapped potential through assets like electric vehicles (EVs) and heat pumps. Using the UK as a primary example, the brief identifies barriers such as inadequate economic signals and passive consumer behavior, and suggests enablers including smart metering, market reform, and digital aggregation platforms. For China, the authors recommend a 'hybrid approach' combining market-based pricing with administrative scheduling to transition away from a reliance on coal-fired power for system flexibility, while emphasizing the need for pilots to understand consumer preferences.

The document argues that demand-side flexibility (DSF) is essential for integrating intermittent renewables and managing the electrification of transport and buildings. It identifies barriers such as inadequate economic signals and consumer passivity, while highlighting enablers like smart metering, digital aggregation platforms, and the need to align services with consumer preferences. For China, the brief suggests a transition from coal-based flexibility to decarbonised sources, proposing a hybrid approach combining market prices with administrative merit orders to manage distributed energy resources.

The briefing urges the Puerto Rican government to move from planning to action following the passage of Act 17, which sets a 100 percent renewable energy goal. It highlights the urgent need for new capacity in solar and battery storage to mitigate reliability risks caused by earthquake damage to the Costa Sur Power Plant and the legacy of Hurricane Maria. The author advocates for the expedited procurement of solar projects, the use of virtual power plant solutions to integrate existing distributed batteries, and the development of energy efficiency programs to reduce demand and lower costs for ratepayers.

The report finds that a significant portion of the U.S. coal fleet is now more expensive to operate than replacing it with new local wind and solar power. In 2018, 74% of the fleet was 'at risk' of being undercut by renewables, a figure projected to rise to 86% by 2025. The analysis emphasizes that these findings are conservative because they only consider resources within 35 miles of existing plants and do not account for broader transmission expansion or combined energy portfolios.

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.

The document details the data sources and specific capacity estimates used by RMI for energy efficiency, virtual power plants, grid enhancing technologies, and clean repowering. It highlights a projected 53GW reduction from energy efficiency and 60GW of dispatchable capacity from flexible loads and storage by 2030, while adopting a conservative 20GW estimate for grid enhancing technologies and 14GW for clean repowering via generator replacement.

The VPP Flipbook outlines how utilities can aggregate distributed energy resources (DERs)—such as batteries, electric vehicles, and smart thermostats—to provide grid services like capacity, energy, and resilience. It details a six-step development process and provides specific examples from utilities including PG&E, National Grid, and Green Mountain Power. The document emphasizes the importance of open-access structures, third-party partnerships, and the integration of VPPs into long-term resource planning to address load growth and decarbonization goals.
