Utility-Scale Batteries Are More Commonly Used For Price Arbitrage - CleanTechnica
A recent survey of utility-scale battery operators reveals that price arbitrage has become the most common primary use for these systems. Price arbitrage involves purchasing electricity when prices are low and selling it when prices are high, allowing battery operators to capitalize on market price fluctuations. In 2023, 66% of all utility-scale battery capacity was used for arbitrage to some extent, with 41% primarily dedicated to this function. The second most common primary use was frequency regulation—maintaining the grid’s 60 Hz frequency—which accounted for 24% of battery capacity, a shift from previous years when frequency regulation was the dominant use. Most of the U.S. utility-scale battery capacity is concentrated in the California Independent System Operator (CAISO) and the Electric Reliability Council of Texas (ERCOT) markets. As of the end of 2024, CAISO reported 11.7 gigawatts (GW) of battery capacity, with 43% primarily used for arbitrage, while ERC

Eaton and ChargePoint have jointly launched an ultrafast DC vehicle-to-everything (V2X) charging architecture called ChargePoint Express Grid, powered by Eaton. This innovative solution delivers up to 600 kW for passenger EVs and megawatt-level charging for heavy-duty commercial vehicles, addressing grid constraints and enabling cost-effective scaling of EV charging infrastructure. The modular design reduces capital expenditures by 30%, occupies 30% less space, and lowers operational costs by up to 30% compared to existing solutions. By integrating onsite renewables, energy storage, and vehicle batteries with local energy markets, the system helps fleets reduce fueling costs and can assist utilities in balancing the electric grid when deployed at scale. The solution will debut at the RE+ trade show in September 2025, with availability for select customers in North America and Europe starting in early 2026 and deliveries in the second half of the year. Eaton will provide custom-engineered, site-ready power infrastructure options, including

The Mobility House, a company specializing in electric vehicle (EV) charging systems, maintains a strong presence in the US, Europe, and parts of Asia, focusing on innovative solutions like vehicle-to-grid (V2G) technology and microgrids. Despite a reduction in federal funding for EV infrastructure in the US, the company continues to advance projects that enhance energy resilience and independence. A notable example is the Brookville Smart Energy Bus Depot in Maryland, which integrates solar power, battery storage, gas generation, and The Mobility House’s ChargePilot smart charging software. This system enables dynamic load management and ensures fleet operations can continue during grid outages by prioritizing essential charging, symbolizing a shift toward energy systems that can operate independently of traditional grids. The Mobility House’s ChargePilot platform is also deployed in major North American transit projects, including New York City’s Metropolitan Transportation Authority and a fleet near San Jose, California, demonstrating its adaptability across various fleet types and grid conditions. While federal support for EV infrastructure is

A recent study by EV charging management firm ev.energy, in partnership with The Brattle Group, reveals that advanced smart EV charging programs in the US could reduce utility costs by $30 billion by 2035. This translates to roughly a 10% reduction in electricity rates for all ratepayers, regardless of EV ownership. The report highlights that EVs, with their large batteries, can function as distributed energy storage assets, allowing utilities to strategically manage charging and discharging to avoid costly grid upgrades. Actively managed EV charging can save utilities between $145 and $575 annually per enrolled vehicle, while bidirectional vehicle-to-grid (V2G) charging can more than double those savings to over $1,300 per vehicle each year. The study underscores the broader economic benefits of EV adoption beyond just environmental impacts. It challenges the notion that EVs are luxury items by noting that transportation costs consume a significant portion of income for lower-income households, and that EVs offer long-term total cost of ownership

On July 29, 2025, California made history by linking approximately 100,000 residential battery storage units in a large-scale Virtual Power Plant (VPP) test, collectively supplying about 535 megawatts of electricity to the grid during peak demand hours. This initiative, led by PG&E in partnership with Tesla and Sunrun, demonstrated the ability of distributed batteries to respond quickly, reliably, and in coordination to support grid stability without causing blackouts or emergencies. The test involved customers across Northern, Central, and Southern California, including underserved and rural communities prone to outages, highlighting the potential of VPPs to alleviate grid stress and reduce reliance on fossil fuel power plants. The California Public Utilities Commission and California Energy Commission have developed programs like the Emergency Load Reduction Program (ELRP) and Demand Side Grid Support (DSGS) to incentivize electricity reduction or backup power provision during peak stress periods. The July 29 test served as a real-world rehearsal to validate these programs and the operational

The article discusses the resurgence and growing momentum of electric vehicle (EV) battery swapping, a concept that briefly appeared in the US during the Obama administration but failed to gain traction. Globally, however, battery swapping is gaining popularity across various EV classes, from lightweight two-wheelers like scooters to heavy-duty trucks. Two-wheelers have been early adopters due to their small, easily swappable batteries and the ability to install swapping stations in compact urban spaces. The four-wheeler market is more complex, requiring automation and significant infrastructure investment, but companies like Chinese automaker Nio have successfully integrated swapping into their business models, offering battery leasing to reduce upfront costs for consumers. Battery swapping also presents advantages for commercial and fleet EV users, such as gig economy drivers who benefit from rapid battery replacement and lack of home charging options. Swapping stations help optimize battery health and can serve as flexible energy storage units, recharging batteries during low grid demand and potentially supplying power back to the grid.
