Batteries and demand flexibility are ready to scale across the EU
The EU battery fleet is projected to grow fourfold from 37 GW in 2025 to 178 GW by 2030, significantly reducing the need for gas-based backup. By 2030, utility-scale batteries could provide short-term flexibility at 20% lower cost than new gas peakers. Additionally, the report highlights the role of demand flexibility: by 2030, 50% of electric vehicles (EVs) could use smart charging to absorb 7% of peak wind and solar generation, and 15% of heat pump demand could be shifted to high-renewable periods, reducing peak demand by 3%. The report recommends that policymakers avoid overbuilding gas capacity, set ambitious non-fossil flexibility targets by January 2027, and accelerate smart meter rollout to enable these technologies.

5 Things We Learned from Analyzing More than 200 Utility Incentives
RMI's analysis of more than 200 utility PIMs reveals a strong preference for 'upside-only' reward structures over penalties, with Return on Equity (ROE) and shared savings being the most common and highest-paying designs. While utilities consistently achieve targets for percentage adder-based and equity-focused PIMs, the report suggests that targets may be set too low. Most PIMs are short-term experiments lasting two to three years, except for fuel cost-sharing and distributed energy resource mechanisms, which often lack end dates to provide regulatory certainty.

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.

Plugging heat in: smart policy can help electrify household heating in Europe
The report argues that high electricity prices, often inflated by policy-related levies, make heat pumps less cost-competitive than gas boilers despite their superior efficiency. It analyzes various policy levers—such as removing levies, reducing VAT, or implementing innovative tariffs—to lower the electricity-to-gas price ratio, which the European Heat Pump Association suggests should be no higher than 2 for competitiveness. The analysis highlights that the Netherlands, with the lowest price ratio (1.4), has significantly higher heat pump sales than countries like Germany, Poland, or Hungary, where ratios exceed 3.

Ember’s response to the call for evidence for the EU Electrification Action Plan
Ember's response to the EU Electrification Action Plan call for evidence emphasizes that while technology readiness is not a barrier—with two-thirds of EU energy demand potentially electrifiable today—cost remains the primary obstacle. The organization urges the Commission to rebalance energy taxation, as industrial electricity taxes are on average triple those of gas, and to incentivize smart consumption through dynamic tariffs. Furthermore, Ember advocates for strategic grid planning and increased investment in energy storage and demand-side response to lower total system costs and integrate renewables.

Reality Check: We Have What’s Needed to Reliably Power the Data Center Boom, and It’s Not Coal Plants
The briefing challenges the notion that coal plants are necessary for grid reliability amidst a data center boom in the US. It asserts that coal plants are prone to unplanned outages, lack the ramp speed required for voltage-sensitive loads, and create grid congestion. The author suggests that over 95 percent of future demand can be met using scalable clean solutions such as battery storage and demand flexibility.

European Electricity Review 2025
In 2024, the EU's electricity transition continued with solar power overtaking coal for the first time and gas generation declining for the fifth consecutive year. Renewables reached a 47% share of the power sector in 2024, up from 34% in 2019, while fossil fuels dropped to a historic low of 29%. This shift reduced power sector emissions to less than half of their 2007 peak and avoided €59 billion in fossil fuel imports since the start of the European Green Deal. Despite this momentum, the report argues that wind power deployment and grid infrastructure must accelerate to meet 2030 targets.

Electric Rates Can Help or Hinder Heat Pump Progress
The document examines how current electricity rate designs in the U.S. often overcharge heat pump users because their peak demand occurs in winter, while grid peaks typically occur in summer. Using data from NIPSCO in Northern Indiana, the brief demonstrates that aligning rates with the actual cost of service could save electrified customers hundreds of dollars annually. It proposes several rate reform options—including seasonal heating rates, time-varying rates, and separate customer classes—while emphasizing the need for affordability measures for low-income households and the long-term evolution of rates as the grid transitions to clean energy.
