Chile faces significant renewable energy curtailment due to limited transmission and storage capacity, with 5,642 GWh of solar and wind energy curtailed in 2024. The report recommends a National Curtailment Reduction Plan, the mass installation of Dynamic Line Rating (DLR) systems, minimum storage requirements for new projects in congested areas, and the creation of a formal demand response market. It also suggests strengthening electricity exchange markets with Argentina and Peru to improve system flexibility.

Chile faces significant energy curtailments due to transmission bottlenecks and a lack of system flexibility, with 2024 curtailments reaching 19% of solar and wind generation. The document argues that while large infrastructure projects like the Kimal-Lo Aguirre line are planned for 2029, immediate action is needed through a 'Clean Flexibility Kit' including battery storage, Dynamic Line Rating (DLR), and demand response markets. It compares Chile's situation with other high-renewable systems like China, Ireland, and California to provide a roadmap of short-, medium-, and long-term recommendations to improve grid efficiency and reduce economic losses for investors.

The document asserts that blackouts are predominantly caused by infrastructure failure, human error, and extreme weather, rather than the deployment of variable renewables. It highlights a significant investment gap in electricity grids, noting that while renewable energy investment has more than doubled since 2015, grid investment has only grown by 24%. The briefing argues that modernising grids with storage, interconnections, and decentralised generation can enhance adequacy, operational security, and resilience, including 'black start' capabilities. However, the IEA warns that grids risk becoming the "weak link" in the energy transition due to underinvestment in ageing assets and the inability to keep pace with rising global electricity demand.

The report examines how battery energy storage can enhance grid reliability—specifically resource adequacy, stability, and resilience—while reducing costs. It contrasts the successful deployment of batteries in Texas (ERCOT) and California (CAISO), where well-defined ancillary services and value stacking have lowered costs, with the PJM region, where high uplift costs and interconnection hurdles persist. The author recommends that regulators and planners define competitive ancillary service products, properly value resource adequacy, and modernize interconnection processes to replace expensive legacy fossil fuel generators.

The policy brief outlines six priorities for U.S. states to leverage the One Big Beautiful Bill Act (OBBBA) and other federal incentives: immediate electric vehicle fleet conversion, permitting and interconnection reform, filling financial gaps via public-private partnerships and aggregate purchasing, improving energy affordability, launching home energy rebates, and attracting cleantech manufacturing. It emphasizes the urgency of acting before federal tax credits expire, specifically noting a September 30, 2025, deadline for EV credits and a July 2026 construction start deadline for certain solar and wind credits.

The report examines how India can transition to cleaner EV charging by utilizing time-of-day (ToD) tariffs, green tariffs, rooftop solar, and open access. While states like Assam, Bihar, Maharashtra, and Madhya Pradesh use ToD tariffs to encourage charging during solar hours (10 AM to 4 PM), the prevalence of nighttime home charging and limited public charging infrastructure (approximately 26,367 stations) hinder effectiveness. Green tariffs are currently restricted to consumers with loads over 100 kW, and while rooftop solar is gaining traction in Delhi and Bengaluru, high deployment costs remain a barrier. Open access for renewable energy is available for operators with a 100 kW load, but high upfront and third-party charges limit its adoption.

The 2025 Utility Roundtable highlighted the need for African power utilities to move beyond dependency on foreign aid by adopting new financing strategies, addressing structural inefficiencies like commercial losses, and strategically integrating renewable energy into fragile grids through regional collaboration and private sector engagement.

The June–July 2025 heatwave in Europe increased electricity demand by up to 14% and caused average daily power prices to double or triple in several countries. While record solar generation of 45 TWh in June 2025 helped maintain daytime stability, the heatwave triggered thermal power plant outages, particularly affecting France's nuclear fleet. The report argues for the deployment of battery storage, interconnection, and demand flexibility to mitigate future extreme weather risks.

The report examines the role of state-owned power companies (SPCs) in emerging markets and developing economies (EMDEs), noting they control approximately 50% of global power station capacity. Through four case studies, it explores specific transition elements: Eskom (South Africa) on just energy transition (JET), NTPC (India) on renewable energy deployment, EVN (Viet Nam) on grid integration, and PLN (Indonesia) on early coal retirement. Key findings highlight that while SPCs can lead low-carbon action due to declining technology costs, they are often hindered by high debt, fossil fuel subsidies, and a lack of comprehensive legal frameworks. The report recommends that governments mandate specific emission targets for SPCs, shift public finance from fossil fuels to clean energy, and that SPCs establish dedicated JET offices and improve data transparency to build stakeholder trust.

The Union of Concerned Scientists finds that major transmission projects in California are experiencing significant delays, averaging an additional 6.1 years beyond original estimates. These delays, driven by utility reprioritization and permitting hurdles, hinder the integration of clean energy and threaten grid reliability. The brief recommends expanding competitive solicitation, increasing agency permitting capacity, implementing public financing, and deploying grid-enhancing technologies.

California possesses vast untapped geothermal potential, particularly in superhot rock resources, which could significantly support the state's clean energy goals. However, the industry faces substantial barriers, including a lack of long-term strategic planning, complex and lengthy permitting processes, outdated regulations, and interconnection uncertainties. The report recommends the creation of a statewide strategic plan, streamlining environmental reviews, updating well regulations, and establishing a clean energy infrastructure financing fund to attract private capital and accelerate deployment.

The report argues that direct electrification is the most efficient way to decarbonize industrial process heat, outperforming alternatives like green hydrogen, bioenergy, and carbon capture. It identifies three primary barriers: economics (high electricity costs relative to fossil fuels), grid readiness (slow interconnection and outdated planning), and technology maturity (lack of awareness and scale for high-temperature solutions). To overcome these, the authors recommend a combination of financial incentives (such as a Clean Heat Production Tax Credit), grid reforms (including surplus interconnection and real-time pricing), and foundational RD&D and workforce training.

The analysis finds that VGI, particularly bidirectional charging (V2G), can generate annual system savings between $1.8 billion and $11.7 billion by 2045. These savings primarily stem from reduced requirements for electricity delivery infrastructure and utility-scale storage. The report recommends that California mandate bidirectional charging capabilities in new EVs and update battery warranties to cover discharging to encourage widespread adoption.

The Tariff Analysis and Cost-Benefit Tool for Solarizing Irrigation (TACTS) is an Excel-based tool created to support the implementation of solarized irrigation in India, specifically under the PM-KUSUM scheme. It addresses barriers such as unviable tariffs, financing difficulties, and lack of administrative buy-in by providing sections for tariff calculation, financing projections, and cost-benefit quantification. The tool emphasizes that grid unavailability significantly affects the levelized cost of energy and argues that solarizing agricultural power can reduce greenhouse gas emissions and state subsidy obligations.

ASEAN electricity demand grew by approximately 50% between 2013 and 2023 and is projected to rise by up to 41% by 2030. While the IEA's Announced Pledges Scenario (APS) targets 100,000 km of transmission line expansion for Southeast Asia between 2021 and 2030, the combined plans of Indonesia, Viet Nam, Thailand, and the Philippines total 45,078 km, covering only about 45% of that target. The document argues that grid planning must shift from merely meeting peak demand to managing the intermittency of wind and solar power, which saw cost reductions of 55% and 85% respectively in the decade to 2020.

The report examines the need for grid modernisation and policy alignment in ASEAN to support the transition to renewables. It highlights the current dominance of fossil fuels, the risk of curtailment seen in Vietnam, and the potential of clean flexibility options such as pumped hydro, battery energy storage systems (BESS), and demand-side management (DSM) to ensure grid stability and enable cross-border energy sharing.

The TACTS tool provides a framework for stakeholders to calculate solar tariffs using the levelized cost of energy (LCOE) method, evaluate risk reduction and financing instruments, and conduct cost-benefit analyses from the perspective of distribution companies (DISCOMs). It specifically supports the implementation of the Pradhan Mantri Kisan Urja Suraksha Evam Utthaan Mahabhiyan (PM-KUSUM) scheme by quantifying avoided generation, power purchase, and transmission costs against the cost of feed-in tariffs.

In 2024, global coal power saw a contradiction: while new completions reached a 20-year low of 44 GW and the EU increased retirements fourfold, China and India saw record-breaking activity. China's new coal starts reached a ten-year high of 94 GW, driven by approval surges in 2022-2023 and supportive policies like capacity electricity tariffs and long-term power purchase agreements. Conversely, OECD nations have significantly reduced planned projects, though their retirement pace remains too slow to meet Paris Agreement goals.

The North Plains Connector (NPC) is a $3.2 billion, 420-mile high-voltage direct current transmission project designed to connect the western and eastern electric grids. The developer, North Plains Connector LLC, has adopted a "landowner-first approach," prioritizing voluntary agreements over eminent domain and modifying the route by adding 50 miles to accommodate local siting requests. Community benefits include $3.9 million in grants distributed via local foundations, over $62 million in federal TSED grants secured for local infrastructure, and the creation of approximately 800 construction jobs. The project also facilitates expanded wind energy exports for the Standing Rock Sioux. While this high-upfront-investment model has reduced local opposition, the document notes it requires "patient capital" and its long-term financial efficiency compared to traditional development remains unproven.

The briefing highlights the bipartisan support and technological advancements, particularly in Enhanced Geothermal Systems (EGS), that are driving geothermal growth in the U.S. It notes that 1.16 GW of capacity is expected by 2028 and that the Trump administration's policies, including permitting exclusions and support from Energy Secretary Chris Wright, favor the sector. However, the author argues that geothermal cannot replace wind and solar, which are necessary to meet a projected 128 GW increase in demand by 2030.
