In the first nine months of 2025, electricity demand in ERCOT, which manages about 90% of the state’s load, reached a record high compared with the same period in … [continued]
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 … [continued]

The United States is rapidly installing grid-scale batteries that are helping to prevent power blackouts, known in German as Dunkelflaute, according to The Guardian. From barely any just a few years ago, the US has now installed 20 GW of grid-scale battery storage for its electric grid — equivalent to … [continued]
Last summer, U.S. electricity demand in the Lower 48 states was greatest at 6:00 p.m. Eastern Daylight Time on July 15, 2024, when it reached about 745 gigawatthours (GWh), based on data in our Hourly Electric Grid Monitor. In our analysis, we calculate each day’s peak according to the hour with … [continued]
In the United States, electricity consumption is growing fastest in Texas, where the Electric Reliability Council of Texas (ERCOT) manages 90% of the load on the state’s power grid. One of the main sources of growing demand for power is large-scale computing facilities such as data centers and cryptocurrency mining operations, … [continued]
