As noted in our recent editorial
in Marine Renewable Energy
, the UK faces a challenge in incorporating large amounts of renewable energy onto its grid without significant new flexible generation, demand-side response… or energy storage capacity. One solution might be for it to ‘borrow’ pumped hydro capacity from Scandinavia, via one of a couple of major interconnectors currently under investigation.This approach is feasible but not for the faint-hearted, Energy Storage Report
has learned from Ilesh Patel, partner at the consultancy Baringa
. “Is an interconnector to Norway an additional form of storage? The answer is yes,” he says. “Will that work all the time? It depends on the economies of arbitrage. You can only store power in Norway’s reservoirs when there’s an economic profit to be had by doing so.
“You might make that bet if you thought you might need that power next week, but it carries a risk with it.”
