To meet its 2045 clean energy goals, California must roughly triple its energy capacity, but faces significant barriers in grid infrastructure, interconnection processes, and land use. The document proposes solutions such as grid-enhancing technologies, interconnection reforms with equity considerations, and incentivizing clean energy on built environments or disturbed lands.

The report examines how grid-enhancing technologies (GETs) can address interconnection bottlenecks in the PJM region, potentially enabling 6.6 GW of new solar, wind, and storage projects by 2027 and providing approximately $1 billion in annual production cost savings.

Earthjustice urges New York State to increase funding for water infrastructure and environmental protection while accelerating the transition from fossil fuels to electricity. The testimony specifically advocates for the NY HEAT Act to downsize the gas system, the RAPID Act to speed up electric transmission, and the Green Transit, Green Jobs bill to electrify bus fleets. It also calls for urgent action on childhood lead poisoning and the reduction of agricultural greenhouse gas emissions, while opposing 'false solutions' like hydrogen and renewable natural gas.

The U.S. clean energy sector saw record growth in 2023, particularly in solar installations and EV sales, supported by the Inflation Reduction Act and Bipartisan Infrastructure Law. However, the transition faces significant headwinds from rising interest rates, supply chain shortages for transformers, and a lagging transmission system. To meet 2035 carbon-free electricity goals, annual renewable installation rates must nearly double, and transmission capacity may need to double or triple.

The report analyzes the impact of a 30% Investment Tax Credit (ITC) on interconnection costs for onshore wind and solar projects in the U.S. It finds that this credit could reduce overall project costs by 3% for solar and 1.7% for wind. More significantly, the analysis suggests the ITC could have bridged the cost gap for 22 GW of withdrawn projects and 15 GW of active projects across five regions, potentially bringing a total of 26-37 GW of capacity to fruition.

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.

The document examines the reliability of natural gas power plants in the US, noting that they are disproportionately prone to failure during extreme weather, such as winter storms. It highlights the 2021 Winter Storm Uri as a critical example of how gas plant failures lead to catastrophic blackouts. To improve grid reliability and mitigate climate change, the author recommends transitioning to clean energy solutions—including renewables, energy storage, and demand-side efficiency—and urges regulators to restrict the approval of new gas plants.

The study investigates the transition of Poland's power system to a 99% reduction in emissions by 2050. The 'base' scenario identifies onshore wind as the dominant generation source, complemented by nuclear power, gas plants with carbon capture and storage (CCS), and hydrogen storage. The analysis emphasizes that a technology-inclusive approach is essential for competitiveness, as scenarios excluding nuclear and CCS result in significantly higher electricity prices and system costs. Key recommendations include maximizing onshore wind deployment, advancing a nuclear fleet exceeding 8 GW, and establishing CO2 transport and storage infrastructure by 2035.

The report evaluates South Africa's REIPPPP, noting its success in attracting over R300 billion in infrastructure investment and selecting over 120 preferred bidders. However, it identifies critical bottlenecks, including limited grid capacity and high transaction costs for bidders. The author argues that maximizing the programme's potential requires improving programme design, enhancing transmission infrastructure, and developing local financial solutions to prevent global funds from crowding out domestic investors. The report also highlights the role of government tax incentives, such as Section 12B of the Income Tax Act, and the importance of integrating battery energy storage systems (BESS) and gas-to-power to stabilize the energy mix and reduce reliance on coal.

The document argues that a cost-effective clean energy transition requires a paradigm shift in transmission planning, moving away from historical reactive models toward holistic planning that accounts for evolving energy systems and climate change uncertainties.

The report identifies a critical gap in the energy policy lifecycle, which it terms the "policy valley of death," where a lack of effective planning prevents financial incentives from achieving emissions targets. It argues that waiting for a decarbonized system to self-assemble through individual projects is inefficient and fails to address the scale of mid-century needs. To resolve this, the authors propose five principles for effective energy planning: being proactive and risk-aware, adopting a multi-jurisdictional and systems-perspective, co-creating plans with all stakeholders, utilizing comprehensive scenario-based analysis, and establishing actionable roadmaps with accountable progress tracking. The document further details five essential components for a durable plan: a stakeholder engagement roadmap, proactive risk-aware analysis, an implementation roadmap, progress tracking mechanisms, and knowledge-sharing centers.

Canada needs to add over 10 gigawatts of new zero-emission electricity annually until 2050 to reach net zero. The author argues that current inclusive permitting processes are too slow and complex. They propose a two-track system: one for major or unproven projects and a second, expedited track for proven technologies like wind, solar, and lithium-ion batteries. This fast-track process would rely on binding, objective 'yes/no' criteria focusing on local government support, avoidance of key ecological features, and the mitigation of uncompensated off-site impacts. The paper concludes that all five orders of government (federal, provincial, territorial, municipal, and Indigenous) have the legal authority to implement these reforms, and recommends that municipal and Indigenous governments lead the project decisions for fast-track approvals.

India would need an additional $101 billion in financing to align with the IEA Net-Zero Emissions (NZE) pathway by 2030, bringing total investment needs to $394 billion. To meet this goal, solar generation must reach 819 TWh and wind 259 TWh, requiring total combined capacity of 571 GW. This necessitates a five-fold increase in annual solar and wind additions by 2027. The report highlights that securing competitive financing is critical to avoid coal capacity lock-in and manage systemic investment risks such as payment delays and PPA renegotiations.

The document analyzes how New York and California are reforming their permitting processes to overcome delays in clean energy deployment, highlighting the use of 'one-stop shops', legal deadlines, and community benefit agreements. While these reforms aim to improve financial viability and public support, the study identifies risks such as imprecise legal language, potential infringement on Indigenous rights, and persistent bottlenecks in grid interconnection that require federal intervention.

The document analyzes how New York and California are reforming permitting processes to overcome delays in clean energy deployment. Key measures include creating 'one-stop shop' agencies, setting statutory time limits for approvals, and mandating community benefit agreements to reduce local opposition. While New York has seen project approval timelines drop from five-ten years to under two years, challenges remain regarding administrative capacity, Indigenous rights, and the failure of state reforms to address the critical backlog of grid interconnections, which remains a federal jurisdiction.

Africa possesses the world's highest untapped hydropower potential, yet only 11% of this capacity is currently installed. While large-scale projects like the Grand Ethiopian Renaissance Dam and the Julius Nyerere Hydropower Plant are advancing, growth is hindered by the need for extensive transmission networks in unstable regions and institutional failures. By 2043, hydropower is forecast to contribute 5.3% of the continent's energy production.

The report asserts that the EPA's proposed rules for coal and gas power plants are technically feasible and will not threaten resource adequacy or operational reliability. It synthesizes six industry-standard studies showing that the U.S. grid can remain stable even if all unabated coal is retired by 2035. The authors argue that reliability risks are institutional rather than technical, stemming from slow interconnection processes and inadequate transmission planning. To manage the transition, the report recommends adopting 'connect-and-manage' interconnection processes, deploying grid-enhancing technologies, and proactively planning transmission for coal retirements.

The Union of Concerned Scientists (UCS) analysis concludes that the United States can meet its climate goals through a rapid phase-out of fossil fuels and a transition to clean energy, which would yield significant economic and public health benefits. While the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) provide critical momentum, the report finds that the U.S. will fall short of its 2030 goals without additional robust policies. The most effective near-term strategy is the decarbonization of the power sector via wind and solar, while long-term reductions depend on the electrification of transportation, buildings, and industry. The report emphasizes that reducing overall energy demand can lower the required scale of new infrastructure and that a just transition must prioritize marginalized communities and hold fossil fuel companies accountable.

The Union of Concerned Scientists (UCS) analysis finds that while the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) accelerate emissions reductions, additional policies are required to meet US climate targets. Achieving net-zero by 2050 requires a rapid phaseout of fossil fuels, a massive scale-up of wind, solar, and energy storage, and expanded electrification and energy efficiency. The report argues that the health and climate benefits of this transition—including avoided premature deaths and reduced climate-caused damage—significantly outweigh the energy system costs.

The report finds that while wind, solar, and battery prices have recently leveled off or risen due to supply chain disruptions, trade issues, and high interest rates, they remain competitive with fossil fuels. It argues that the long-term trend of cost reduction will continue and recommends that regulators use competitive procurement, leverage Inflation Reduction Act (IRA) incentives, and reform interconnection and transmission planning to lower costs.
