Assessing the value of battery energy storage in future power grids

That means you need many hours of energy storage capacity (megawatt-hours) as well. The study also finds that this capacity substitution ratio declines as storage tries to displace more gas capacity. "The first gas plant knocked offline by storage may only run for a couple of hours, one or two times per year," explains Jenkins.

How to estimate your energy use

The energy price cap is often talked about as a particular price, based on a ''typical'' user. The current energy price cap sets bills at £1,717 per year for a ''typical household'' until 31 October 2024.But what does that actually mean for you? The energy price cap is actually a cap on the unit rates you pay for each unit of energy you use, not the total amount.
