title: Behaviour of storage technologies
short_description:
description: |
In this section you can determine the behaviour of electricity storage technologies such as batteries. These technologies
are considered flexible, because both their supply and demand can be increased, reduced or shifted in
time if needed (see the <a href="/scenario/flexibility/flexibility_overview/what-is-flexibility">
Flexibility overview</a> for background information). </br></br> The ETM models three types of storage behaviour.
<br /><ol><li>By default, storage behaves like any other flexible technology. Each storage technology has a
<i>willingness to pay</i> that indicates the maximum electricity price for which it is willing to charge electricity.
If the electricity price in a given hour is lower than a technology's willingness to pay, the storage technology will charge. </br></br>
Similarly, each technology also has a <i>willingness to accept</i>, which indicates the minimum
electricity price for which it is willing to discharge the stored electricity. This
is similar to the concept of 'marginal costs' for flexible power plants.</li> </br>
<li>Optionally you can choose to activate a

charging and discharging behaviour of storage. Rather than looking at the electricity
price in the current hour only, the battery will look ahead in time to identify interesting moments
for charging and discharging. It does so by looking at peaks and troughs in the

residual load curve</a>.</li> </br>
<li>Finally, storage systems that are integrated with wind turbines or solar plants only store electricity
when the production of the connected renewable energy source exceeds the connection capacity to the grid.
They release their electricity when the production drops below that capacity. The storage system itself has
no further interaction with the rest of the electricity system.</li></ol><br/>
