No, not a fast repair for Norway’s electrification

Professor Ole-Morten Midtgård, my colleague within the Division of Electrical Vitality right here at NTNU, downplays Norway’s power future in Dagens Næringsliv on November 14 with the title “Electrification of Norway is straightforward”. He factors out {that a} threefold improve in onshore wind power and a two hundredfold improve in photo voltaic power is sufficient to totally electrify Norway by 2050.

It might work as a tutorial math train, however not in apply.

Firstly, such a weather-dependent power system will neither assure safety of provide nor guarantee low, secure electrical energy costs.

Based on NVE, there will likely be extraordinarily dry years sooner or later during which little wind coincides with years with little rain and influx into the reservoirs. Furthermore, the identical climate is correlated with our neighboring international locations. NVE additionally exhibits that we’ll have intervals of collapse in electrical energy costs and everlasting intervals of extraordinarily excessive electrical energy costs. We merely run the danger of working out of energy after we want it most.

There is no such thing as a indication that this will likely be straightforward.

Secondly, 45 terawatt hours (TWh) of recent photo voltaic power per yr makes full sense.

This alone will equate to an estimated 60 gigawatts (GW) of recent, unregulated energy. Our hydropower at present has not more than 30 GW of dispatchable capability and won’t come near with the ability to each steadiness Norway’s electrical energy consumption and on the similar time steadiness this quantity of unregulated photo voltaic power.

Altering cloud cowl will make the balancing problem astronomical.

One other professional query is what we’re going to do with this photo voltaic power in the course of the day. In apply, it can do nothing greater than restrict the quantity of photo voltaic power we will import at nearly no price from different international locations with extra sunshine and higher circumstances for photo voltaic power.

Some imagine an answer is to mix photo voltaic power with 4 hours of battery storage. But when we enter this into the NVE calculator with actual price estimates for storage, the power prices are 245 øre per kilowatt hour. Sure, though the battery life is brief.

Photo voltaic power and storage in Norway is nearly unattainable to calculate at dwelling.

In its conversion state of affairs, DNV factors out that a big a part of future wind power needs to be used to supply hydrogen with low power consumption and to not electrify society. It has to do with the truth that a lot electrical energy is produced on the similar time that the buyer can’t use it.

Midtgård foresees a complete of 30 TWh of recent onshore wind power and 45 TWh of recent photo voltaic power per yr to completely electrify Norway. If Pareto Securities’ estimates are taken into consideration, it will price an insane NOK 810 billion, making offshore wind subsidies look like a bracket.

It additionally contains electrical energy networks, which take into consideration that energy have to be transported over lengthy distances. However then the social prices of an influence scarcity throughout a part of the yr and intensely excessive electrical energy costs will not be taken into consideration. Or that we construct up loads of unregulated energy that’s poorly used.

Present all positions

It additionally doesn’t take into consideration the social prices related to territorial conflicts with populations, or the environmental prices related to nature loss.

We do not resolve the Norwegian power trilemma with empty sentences that every part is so easy.

In any case, photo voltaic and wind power can play a task in supplementing Norway’s future power combine. However we are going to want a way more sturdy power combine if we’re to get critical about totally electrifying Norway. General, there are less expensive and climate-smart complete options than what Midtgård outlines.(Circumstances)Copyright Dagens Næringsliv AS and/or our suppliers.
