Grid batteries have a halo effect for other power generators too. Most thermal power plants\u2014coal, gas, nuclear\u2014prefer to run at a steady pace. Ramping up and down to match demand takes time and costs money, but with batteries soaking up some of the variability, thermal power plants can stay closer to their most efficient pace, reducing greenhouse gas emissions and keeping costs in check.<\/p>\n

\u201cIt\u2019s kind of like hybridizing your car,\u201d Zahurancik said. \u201cIf you think about a Prius, you have an electric motor and you have a gasoline motor and you make the gas consumption better because the battery absorbs all the variation.\u201d<\/p>\n

Another grid battery feature is that they can reduce the need for expensive grid upgrades, said Stephanie Smith<\/a>, chief operating officer at Eolian, which funds and develops grid energy storage systems. You don\u2019t have to build power lines to accommodate absolute maximum electricity needs if you have a battery\u2014on the generator side or on the demand side\u2014to dish out a few more electrons when needed.<\/p>\n

\u201cWhat we do with stand-alone batteries, the more and more of those you get, you start to alleviate needs or at least abridge things like new transmission build,\u201d Smith said. These batteries also allow the grid to adapt faster to changing energy needs, like when a factory shuts down or when a new data center powers up.<\/p>\n

On balance this leads to a more stable, efficient, cheaper, and cleaner power grid.<\/p>\n

Charging Up<\/h2>\n

As good as they are, lithium-ion batteries have their limits. Most grid batteries are designed to store and dispatch electricity over the course of two to eight hours, but the grid also needs ways to stash power for days, weeks, and even months since power demand shifts throughout the year<\/a>.<\/p>\n

There are also some fundamental looming challenges for grid-scale storage. Like most grid-level technologies, energy storage requires a big upfront investment that takes decades to pay back, but there\u2019s a lot of uncertainty right now about how the Trump administration\u2019s tariffs<\/a> will affect battery imports, whether there will be a recession, and if this disruption will slow electricity demand growth in the years to come. The extraordinary appetite for batteries is increasing competition for the required raw materials, which may increase their prices.<\/p>\n

Though China currently dominates the global battery supply chain<\/a>, the US is working to edge its way in. Under the previous administration, the US Department of Energy invested billions in energy storage factories<\/a>, supply chains, and research. There are dozens of battery factories in the US<\/a> now, though most are aimed at electric vehicles. There are 10 US factories slated to start up this year, which would raise the total EV battery manufacturing capacity to 421.5 gigawatt-hours per year<\/a>. Total global battery manufacturing is projected to reach around 7,900 gigawatt-hours<\/a> in 2025.<\/p>\n
