This report by the Stockholm Environment Institute provides a 2025 overview of Colombia's electricity transmission sector, detailing the institutional framework of the National Interconnected System (SIN) and the structural challenges hindering the integration of new renewable energy generation.

This report by RMI examines how flexible service connections (FSCs) can accelerate the deployment of electric truck charging infrastructure by allowing fleets to connect to the grid faster in exchange for limiting power draw during peak hours. Using modeling of utility feeder data from PG&E and National Grid, the report demonstrates that FSCs can significantly increase charging capacity and reduce the need for immediate, costly grid upgrades.

This report by the Environmental and Energy Study Institute examines reconductoring—the process of replacing existing electrical transmission cables with advanced conductors—as a rapid and cost-effective method to increase the capacity of the U.S. energy grid. The author argues that reconductoring can bypass lengthy permitting processes, reduce energy costs, and support the transition to clean energy by enabling the connection of stalled renewable projects and meeting rising electricity demands from electric vehicles and data centers.

This briefing by RMI explains how 'flexible service connections' can accelerate the deployment of electric truck charging infrastructure by allowing fleets to access underutilized grid capacity without waiting for multi-year utility upgrades.

This report by RMI examines how public utility commissions in Minnesota, Massachusetts, and New York use different cost allocation strategies during proactive distribution planning to balance grid investment needs with customer affordability during the electrification of buildings and transportation.

This policy brief by RMI argues that Virtual Power Plants (VPPs) can mitigate the grid constraints currently delaying the interconnection of data centers and other large loads in the United States. The document proposes three commercial models to accelerate VPP deployment and suggests policy reforms in interconnection, integrated planning, and customer protection to ensure the US remains competitive in the AI race.

This policy brief by RMI argues that PJM's slow interconnection process and high network upgrade costs are driving a capacity crisis in the mid-Atlantic grid. The document highlights how the time required to bring new generation online has increased to eight years, causing capacity auction prices to skyrocket and increasing costs for ratepayers. RMI proposes four primary solutions: implementing third-party automation software, reforming Energy Resource Interconnection Service (ERIS), utilizing advanced transmission technologies (ATTs), and prioritizing proactive regional transmission planning.

This guide by RMI outlines how state regulators in the United States can implement recently passed legislation to deploy advanced transmission technologies (ATTs), such as grid enhancing technologies (GETs) and advanced conductors, to lower electricity costs and improve grid reliability.

This report section outlines the requirements for Turkey to reach its 2035 renewable energy targets, emphasizing the need for grid modernization and the removal of bureaucratic barriers for diverse solar projects over the continued subsidization of domestic coal.

This report by Ember analyzes the financial implications of Türkiye's decision to provide purchase guarantees for domestic coal power plants until 2030. It argues that the $8.7 billion allocated for these subsidies contradicts the country's renewable energy goals, as solar power has become the cheapest source of electricity generation in Türkiye. The report suggests that redirecting these funds toward grid modernization and removing bureaucratic barriers to diverse solar applications could help Türkiye achieve its 2035 target of 120 GW of installed wind and solar capacity.

This supplemental report by RMI addresses the barriers to scaling Virtual Power Plants (VPPs) in the United States, specifically focusing on the challenges posed by inconsistent metering and telemetry requirements for distributed energy resources (DERs).

This report by Ember argues that smart grids are essential for ASEAN to integrate increasing shares of renewable energy, maintain industrial competitiveness, and reduce economic losses from power outages. It estimates that investments between $4 billion and $10.7 billion are required to modernize the region's power systems, which could in turn create up to 649,000 jobs and unlock $2.3 billion in annual economic value by 2040.

This report by Ember analyzes the technical and economic feasibility of achieving 24-hour solar electricity generation using solar panels paired with battery storage. It demonstrates that in sunny regions, near-continuous solar power is now cost-competitive, often cheaper than new coal or nuclear power, due to rapid declines in battery costs and the adoption of Lithium Iron Phosphate (LFP) technology.

This policy brief by RMI examines how US governors are addressing rising electricity costs, which have increased by an average of 23% over the last decade. The document highlights actions taken by governors in at least 14 states since 2023 to balance immediate customer relief with long-term system cost containment, while warning against superficial measures like one-time bill credits that do not address underlying affordability challenges.

This briefing from RMI argues that state public utilities commissions (PUCs) in the United States must increase their regulatory agility to manage the complexities of the energy transition, including aging infrastructure and demands for cleaner service, while maintaining their core mandates of safety, reliability, and affordability.

This report by Ember analyzes the accelerating deployment of battery storage and solar power in the United States, highlighting how batteries are enabling higher solar penetration and displacing fossil fuels, particularly in California and Texas.

This report defines "energy parks" as large-scale microgrids that co-locate renewable energy generation, storage, and electricity consumers (loads) behind a single point of interconnection (POI) to the bulk power grid. The authors argue that this model reduces equipment costs, accelerates the "time to power" for industrial loads, and provides flexible grid services. The document outlines the evolution of these parks from simple solar farms with high inverter-loading ratios to complex hybrids involving thermal batteries and hydrogen electrolysis. It identifies significant regulatory hurdles, including interconnection queue delays, wholesale market participation rules, and state-level utility monopolies, and proposes a shift toward treating energy parks as "digital resources" with a universal participation model.

This briefing by RMI estimates the climate impacts of the transmission provisions within the draft Energy Permitting Reform Act of 2024 (EPRA). The analysis finds that the EPRA, in conjunction with FERC Order 1920, would significantly accelerate the expansion of regional and interregional transmission, enabling the deployment of clean energy to meet growing load and displace fossil fuel generation. In a central scenario, the EPRA is estimated to reduce cumulative US grid emissions by 6.5 Gt CO2 equivalent through 2050.

This introductory guide by RMI explains performance-based regulation (PBR) as a tool to modernize utility regulatory frameworks to better accommodate renewable energy, distributed resources, and electrification while addressing affordability and emissions.

This guide by RMI introduces Performance-Based Regulation (PBR) as a regulatory approach for electric utilities designed to align utility incentives with customer and societal interests. It contrasts PBR with traditional cost-of-service regulation (COSR), which the document argues creates perverse incentives such as 'gold plating' and 'capex bias' that hinder the clean energy transition. The guide details various PBR tools—including revenue decoupling, multi-year rate plans, and performance incentive mechanisms—and provides a framework for moving from incremental to comprehensive PBR reform.
