Weighing GHGs in New York
The report examines the impact of New York's CLCPA greenhouse gas accounting method, which differs from the UNFCCC standard. It finds that the CLCPA approach increases the distance to statutory targets and alters cost-effective abatement strategies, though substantial reductions remain necessary regardless of the method used. The authors argue that marginal abatement cost data for different gases and sectors is essential for evaluating the 2025 New York State Energy Plan.

From baseload to flexibility: How is coal’s role in China changing
China is repositioning its coal fleet to provide system flexibility, with the entire existing fleet on track to be retrofitted by 2027. While technical capacity is increasing, the report argues that full flexibility is constrained by power market design and dispatch practices. It emphasizes that as coal retrofit potential plateaus, the rapid scale-up of clean flexibility, particularly battery energy storage, is essential to avoid locking in emissions beyond 2030 and to maintain grid stability as renewables become dominant.

Setting the Scene - Coal flexibility in China: context, drivers, and policy evolution
China is repositioning its coal fleet to serve as a regulatory and security resource to manage the variability of its growing renewable energy sector. This transition is driven by a critical need for short-term flexibility, with the IEA estimating that these needs will be three times higher in 2030 than in 2022. To achieve this, the Chinese government has implemented a series of Five-Year Plans and policies, including a target to retrofit "above 200 GW" of coal capacity for flexibility between 2021 and 2025. Technical efforts focus on lowering minimum loads (ML) to 25-40% of rated capacity and decoupling heat and electricity generation in combined heat and power (CHP) units. Financial mechanisms supporting this shift include a coal capacity pricing mechanism introduced in 2024 and the use of infrastructure real estate investment trusts (REITs) for eligible plants.

Measuring the Impact - China’s coal fleet is becoming more flexible, but much of its potential remains untapped
China has rapidly expanded its flexible coal power capacity, exceeding its 2025 national target and positioning itself to meet a 2027 goal of retrofitting 500-700 GW. By the end of 2024, total flexible coal capacity exceeded 600 GW, with significant progress in provinces like Guangxi, Inner Mongolia, Shanxi, and Xinjiang. While coal utilisation is generally declining and showing greater seasonal variability due to renewable growth and demand peaks, the document notes that the full potential of this technical flexibility is not yet reflected in system operations due to market design and institutional arrangements. The transition is supported by a capacity pricing mechanism and diversified revenue models, though flexible operation increases costs through higher maintenance, reduced fuel efficiency at low loads, and accelerated depreciation.

Le mythe du gaz comme énergie de transition
The report challenges the narrative of fossil gas as a necessary transition fuel for grid flexibility. It distinguishes between Open Cycle Gas Turbines (OCGT), which are agile but inefficient, and Combined Cycle Gas Turbines (CCGT), which are efficient for baseload power but suffer from premature aging, higher emissions, and reduced profitability when used for peak demand. The author highlights that CCGT viability often relies on costly government capacity mechanisms funded by consumers. Furthermore, a global shortage of gas turbines is delaying projects and increasing costs. The document advocates for replacing gas with sustainable flexibility solutions, including battery storage, pumped hydro, demand-side response, and improved interconnections, urging financial institutions to cease funding new gas power projects.

The myth of gas as a bridge fuel
The report challenges the narrative of fossil gas as a necessary 'bridge fuel' for grid flexibility. It argues that Combined Cycle Gas Turbines (CCGTs), which dominate new developments, are designed for baseload rather than peakload, and using them for flexibility reduces their lifespan and increases emissions. The document highlights that gas plant profitability is often maintained through costly consumer-funded capacity mechanisms and notes a critical global shortage of gas turbines. It concludes that sustainable alternatives—such as battery storage, pumped hydro, demand-side response, and grid enhancements—provide more efficient and cheaper flexibility, urging financial institutions to cease support for new gas projects.

Building flexibility is central to accommodating increasing solar
India needs to build system flexibility to absorb high and variable renewable generation, moving beyond simple capacity additions. The report identifies three primary levers: improving the flexibility of the coal fleet by lowering minimum technical limits, scaling energy storage (BESS and pumped hydro), and accelerating demand-side flexibility through smart meter deployment and attractive time-of-day tariffs.

2025 saw significant solar curtailment to preserve system stability
In 2025, India experienced significant solar curtailment, estimated at 2.3 TWh between late May and December, primarily due to the inability of the coal fleet to ramp down sufficiently during periods of low daytime demand. This was exacerbated by weaker-than-forecast demand growth in 2025, driven by mild temperatures and increased behind-the-meter solar generation. The report highlights that while operational errors in forecasting contributed to the issue, the structural lack of flexibility in coal plants—many of which must operate above a minimum thermal load of 55%—creates a systemic challenge as solar capacity continues to grow faster than demand.

Vers un réseau plus abordable et fiable grâce à la modulation de la consommation
The document advocates for demand-side flexibility in Canada to manage increasing electricity demand from electrification and AI data centers. It highlights that relying solely on new production capacity is costly and inefficient. By using tools like smart thermostats, EV charging management, and virtual power plants, the grid can reduce peak loads (peak shaving) or shift consumption to off-peak hours (load shifting). This approach benefits utilities by delaying infrastructure upgrades and benefits consumers through lower bills. The text cites successful pilot programs in Quebec, British Columbia, and Ontario, while urging federal and provincial governments to integrate demand flexibility into clean energy policies and regulations.

Too Smart to Ignore: How flexible demand can help build a cleaner, more cost-effective electricity system
The report argues that flexible demand—the ability to shift or reduce electricity use during peak periods—can significantly lower system costs and defer expensive infrastructure upgrades in Canada. While some provinces like Ontario, Quebec, and British Columbia are implementing demand-side management (DSM) programs, the report finds that these resources remain under-deployed due to outdated regulatory frameworks, misaligned financial incentives for utilities and consumers, and a tendency for planners to treat DSM as a passive load reduction rather than an active grid resource.
