Interesting looking at the data, that Norway generates 4x the electricity of NZ and they are roughly the same size and population I assume it exports most.

A lot of the electricity is gobbled up by a few aluminum plants, but in addition to that Norway is a very electrified country. We don't use gas at the consumer level at all (except for grilling 2 months of the year, lol) and are rapidly moving transportation to electricity.

In a normal year we are a net exporter of electricity, but it's only around 10% that is exported.

UK generation is 30GW right now, so this is ~ 5%

By enabling the trade of renewable energy between the two countries, North Sea Link will help reduce the burning of fossil fuels in the UK and avoid 23 million tonnes of carbon emissions by 2030.

The 450-mile cable, which connects Blyth in Northumberland with the Norwegian village of Kvilldal, near Stavanger, will start with a maximum capacity of 700 megawatts (MW) and gradually increase to the link’s full capacity of 1400MW over a three-month period. The gradual increase in capacity follows the Norwegian system operator’s standard approach for integrating new interconnectors. Once at full capacity, NSL will provide enough clean electricity to power 1.4 million homes.

North Sea Link will be the fifth interconnector for National Grid, which also operates links to Belgium, France and the Netherlands. By 2030, 90% of electricity imported via National Grid’s interconnectors will be from zero carbon sources saving 100 million tonnes of carbon – equivalent to taking two million cars off the road.

NSL has taken six years to build. Laying of the undersea cables began in 2018 and more than four million working hours have been spent on the project, including 5,880 working days at sea.

Norwegian power generation is sourced from hydropower plants connected to large reservoirs, which can respond faster to fluctuations in demand compared to other major generation technologies. However, as the water level in reservoirs is subject to weather conditions, production varies throughout seasons and years.

When wind generation is high and electricity demand low in Britain, NSL will enable renewable power to be exported from the UK, conserving water in Norway’s reservoirs. When demand is high in Britain and there is low wind generation, hydro power can be imported from Norway, helping to ensure secure, affordable and sustainable electricity supplies for UK consumers.
