<p>We recognise that electricity storage technologies, including pumped hydro storage,
provide an important source of flexibility to our energy system. We currently have
around 3GW of storage capacity on our system, of which the vast majority is pumped
hydro storage. The Electricity System Operator estimates that, by 2050, there could
be 12-29 GW of total storage capacity on our system.</p><p> </p><p>Our 2017 Smart
Systems and Flexibility Plan and 2018 Progress Update set out a range of actions to
remove barriers to storage and ensure flexibility is fairly valued in our energy markets.
Pumped storage hydro is able to access the Capacity Market in the same way as other
technologies, though a number of issues were raised in the recent Capacity Market
review “Call for Evidence” which we will be considering.</p>
