The existing link is 2gw and (again, according to the Wikipedia) supplies about 5% of UK electricity. So its a start, but not the capacity for full cross resource pooling along the lines proposed by some.
From Transmission and Distribution World, the link to the Netherlands is 1gw. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

I presume that is the "proposed" UK/Norway link. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
One of the appealing things about pumped hydro storage is the responsiveness - that same source notes that as a spinning reserve, powered by the conventional hydro facility using the same upper reservoir, as able to come online in 15 seconds. And AFAIR there is a pumped hydro installation somewhere in the UK that can reverse from storage to power generation in a handful of minutes.

That form of storage on a grid will be especially useful when volatile energy sources in the portfolio are running below average demand, as they allow energy to be brought in over the grid to grid HVDC links in off-peak periods and stored for use during peak demands.
The Wikipedia mentions that it, too, was originally planned for use with shifting nuclear generated electricity from off-peak to on-peak, and with the switch in nuclear plans a sister plant at Exmoor was never built. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
