Utility-scale batteries have significantly faster response times compared to traditional power plants such as fuel-fired generators or hydropower.
Response Time Comparison:
- Utility-scale batteries, including advanced types like vanadium flow batteries, can respond in the range of milliseconds. For instance, Invinity vanadium flow batteries have demonstrated response times as fast as 110 milliseconds (0.11 seconds), allowing them to meet or exceed the fast response requirements of many grid ancillary services that typically demand response within 2 seconds or less.
- More broadly, grid-scale batteries generally achieve response times under 150 milliseconds, which is much faster than the response time of conventional generators.
- In contrast, traditional fuel-fired generators and hydropower plants have slower response times. These generators often require several seconds to minutes to ramp up or down to adjust their output, due to mechanical and thermal constraints.
Implications:
This extremely fast response capability allows utility-scale batteries to provide critical grid services such as frequency regulation, load balancing, and fast frequency response much more effectively than traditional power plants. Their near-instantaneous response enhances grid stability and makes them valuable for integrating variable renewable energy sources.
In summary, utility-scale batteries outperform traditional power plants by orders of magnitude in terms of response time, switching output nearly instantaneously (sub-second), while traditional plants take significantly longer to adjust their output.
