In-brief analysis

September 22, 2025

In our annual survey of power plant activity, we ask operators of utility-scale batteries how they are using their systems, and one use case is increasingly prevalent: price arbitrage. Arbitrage involves buying electricity when prices are relatively low and selling that electricity when prices are high.

Utility-scale battery systems can be used for many applications. In previous years, we asked operators to identify the ways they used their batteries. Common use cases included price arbitrage as well as frequency regulation, excess wind and solar generation, system peak shaving, load management, and more.

Beginning with the 2023 survey, we asked operators to identify the primary use case for their battery system. Last year, operators responded that 66% of all utility-scale battery capacity had arbitrage among its uses and that 41% of the

Sneezing from cats, dust mites, or mold may one day be preventable with a flip of a switch. Researchers at CU Boulder found that UV222 light can alter allergen proteins, reducing allergic reactions without dangerous side effects. Within 30 minutes, airborne allergens decreased by up to 25%. The team imagines portable devices that could shield people in homes, schools, and workplaces from harmful triggers.

A magnitude 3.3 earthquake near Zakynthos, Zákynthos, Ionian Islands, Greece, was reported only 22 minutes ago by the National Observatory of Athens (NOA), considered the main national agency that monitors seismic activity in Greece. The earthquake occurred at a very shallow depth of 5. km beneath the epicenter early afternoon on Monday, September 22nd, 2025, at 3:17 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.8 earthquake. Other agencies reporting the same quake include The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 3.1, The Seismological Laboratory of the University of Athens (UOA) at magnitude 3.1, and the citizen-seismograph network of RaspberryShake at magnitude 3.3.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Agios Leon (pop. 390) located 4 km from the epicenter, Mouzaki (pop. 1,700) 10 km away, Lithakia (pop. 1,300) 11 km away, and Katastarion (pop.
