This report argues that traditional integrated resource planning (IRP) modeling assumptions are outdated for modern grids characterized by renewable energy, distributed resources, and climate change impacts. It advocates for updating assumptions across capacity expansion, production cost, and resource adequacy models, while integrating an energy equity lens to account for human impacts such as health and affordability.

This guide by RMI outlines the application of thermal batteries to decarbonize heating in the United States chemical and petroleum refining sectors, which contribute 5% to 6% of US greenhouse gas emissions. It details how these batteries store electricity as heat in materials like graphite or bricks to provide high-temperature heat for industrial reactions and distillation, potentially reducing heat emissions by up to 99%.

This report by Ember analyzes how the decline in Battery Energy Storage System (BESS) costs can accelerate the phase-down of coal power in India between 2024 and 2032. Using a least-cost optimized (LCO) model, the authors identify that while solar growth is rapid, the transition is limited by the cost-effectiveness of storage for non-solar hours. The report argues that BESS costs must fall by 15% annually to limit new coal capacity to levels projected in the 14th National Electricity Plan (NEP), and must drop by over 50% from current levels to potentially eliminate the need for any new coal additions.

This briefing by RMI argues that battery energy storage systems (BESS) are a cleaner, more flexible, and often more cost-effective alternative to fossil fuel resources for maintaining electric grid reliability. It details how batteries can manage variable renewable energy, provide critical stability services, and support grid restoration, while urging utilities to adopt all-source procurement processes to identify the most cost-optimal reliability solutions.

The report 'Making clean power flexy' by Ember argues that clean flexibility—specifically battery storage and demand side flexibility (DSF)—is essential to integrate the rapid growth of wind and solar power in the European Union and phase out fossil fuel 'peakers'. It highlights a significant gap in national policy targets for these technologies despite projections that EU flexibility needs will double by 2030.

This research paper examines the adoption of electricity markets in Indian states to facilitate the clean energy transition. It finds that while real-time markets are growing, overall market penetration remains low (7% of demand) due to inflexible long-term power purchase agreements (PPAs), unpredictable pricing, and poor forecasting. The paper highlights that states like Gujarat and Tamil Nadu could achieve significant cost savings by shifting toward day-ahead markets and recommends PPA renegotiation, the introduction of ancillary services, and coordinated resource adequacy planning.

This report by RMI examines the potential for demand-side flexibility (DSF) within China's industrial sector to support the integration of renewable energy and the development of a zero-carbon power system.

This briefing by Global Energy Monitor and the Centre for Research on Energy and Clean Air (CREA) analyzes a surge in coal power permitting and construction in China during the first half of 2023. The report finds that new projects are being approved at a pace of more than one plant per week, often ignoring central government policies that restrict new coal to a 'supporting' role for clean energy. The authors argue that this 'coal rush' is driven by a desire to maximize carbon-intensive capacity before the 2030 emissions peak, outdated grid management, and a shift away from fossil gas, potentially undermining China's long-term climate commitments.

This policy brief by Ember argues that Europe must double its electricity interconnection capacity over the next ten to fifteen years to meet climate neutrality goals and ensure security of supply. It highlights a gap between current expansion plans and actual power system needs, warning that slow project timeframes—averaging nine years—could create bottlenecks for wind and solar expansion.

This policy brief by Ember provides recommendations for the European Commission's Grids Action Plan, arguing that power grids must become the backbone of the energy system to achieve a carbon-neutral economy by 2050. The document identifies critical gaps in investment, data transparency, and planning frameworks, proposing a shift toward anticipatory grid investments and integrated system-level planning to ensure grid constraints do not hinder renewable energy deployment.

This fact sheet details a GBP 300 million green bond issued by Northern Powergrid on June 16, 2020, to finance and refinance projects related to grid reliability, renewable energy integration, and environmental mitigation.

The research paper proposes a wholesale electricity market design to facilitate rapid decarbonization by combining a centralized regional spot market for short-term efficiency with decentralized forward procurement for long-term investment. The authors argue that this approach minimizes the risks of over-investment and political interference associated with centralized capacity markets while leveraging public policy instruments to internalize carbon externalities.

This fact sheet from the Environmental and Energy Study Institute describes the role of energy storage in enhancing grid resilience, integrating intermittent renewable energy, and managing peak demand. It details various storage technologies—including pumped-storage hydropower, batteries, compressed air, thermal, hydrogen, and flywheels—comparing their technical specifications, costs, and current global applications.

A fact sheet detailing a BRL621 million (USD179 million) green bond issued by ISA CTEEP on April 23, 2018, to finance electricity grid infrastructure in Brazil.

This report by the Climate Policy Initiative and Indian School of Business examines the challenges of integrating high levels of renewable energy into India's power grid, specifically focusing on the need for system flexibility and the risk of coal-based assets becoming stranded. The authors propose that converting existing baseload coal plants into flexible plants is a cost-effective short-term solution to provide necessary operational reserves and mitigate financial risks for investors.

This briefing by RMI argues that current commercial electricity rate designs, specifically noncoincident demand charges, encourage inefficient battery storage use that can conflict with the needs of renewable-heavy power grids. The document advocates for a transition to time-varying rates and compensation for grid services to better align customer incentives with system-wide operational requirements.

This RMI briefing discusses the significant electricity demand generated by the legal marijuana industry in the United States and proposes strategies for utilities and regulators to manage this load. It suggests that energy efficiency investments, on-site renewables, and time-varying rates to shift consumption to periods of low net load can help integrate renewable energy and reduce operating costs for growers.

This report by Energy Innovation examines the necessity of grid flexibility to integrate increasing shares of variable renewable energy. It details short-term operational improvements, long-term planning strategies, and various physical and market-based resources—such as demand response and energy storage—that can balance supply and demand dynamically.

This issue brief from the Environmental and Energy Study Institute examines the role of energy storage technologies in mitigating electricity industry challenges, integrating renewable energy, and improving grid reliability. It details various storage technologies—ranging from pumped hydro and compressed air to advanced batteries and flywheels—and analyzes the impact of U.S. federal policies, specifically FERC orders and Department of Energy (DOE) initiatives, in overcoming implementation barriers.

This policy brief from the Environmental and Energy Study Institute (EESI) examines the role of energy storage technologies in mitigating electricity industry challenges, integrating renewable energy, and improving grid reliability. It provides a technical overview of various storage methods, analyzes the impact of U.S. federal policies and legislation, and highlights specific large-scale implementation projects across the United States.
