Swedish Power Shortages Because of Renewable Energy

Sweden’s Lack of Electricity Capacity Is Threatening Growth

A shift toward renewables is overwhelming the nation’s grid, leaving a potential Olympic Games in 2026 relying on reserve generators.

Global trade wars and weakening export markets are not the only potential dampers on Sweden’s growth. There’s also a homegrown problem: a lack of power capacity. 

The dire situation stems from the closing of the nation’s oldest reactors and a shift to wind at a time when the grid is already struggling to keep up with demand in major cities. The shortage, which impacts the nation’s main urban areas, is threatening everything from the rollout of a 5G network in the capital to investments in giant data halls and new subway lines. It could even derail Stockholm’s bid for the 2026 Winter Olympics.

It’s a stark change from the decades of cheap, surplus electricity that propelled the Nordic region’s biggest economy into one of the richest and most industrialized nations in the world. Now, electricity supplies in urban areas can’t keep up and that could exacerbate a slowdown already impacted by global uncertainty and Brexit.

“Citizens and companies are worried, irritated and even angry,” said Jonas Kamleh, a strategist for the City of Malmo, the nation’s third biggest. “How could this situation arise in the engineering nation of Sweden?”

The answer is a very ambitious green agenda. Sweden is halfway through a plan to replace the output from four reactors in the industrial south with thousands of wind turbines in the north. But grid connections, some dating back to the 1950s, aren’t up to scratch so the power isn’t shipped to where it’s really needed. And to make matters worse, city demand is surging at a faster-than-expected pace because of the electrification of everything from transport to heating.

Sweden Will Meet Its 2030 Green Energy Target 12 Years Early

The huge wind-power push could still cause growing pains.

You can’t fault the Swedish Energy Agency for ambition: Last year, it decided to increase its target for renewable energy, aiming to produce an additional 18.4 terawatt hours per year by 2030. That’s a huge amount—it would be enough to provide all the power needs for the U.K.’s 66 million citizens for just under three days.

It seems, however, that it won’t be met in 2030 after all. Instead, Sweden should reach the target by as early as the end of this year.

Behind this unexpectedly rapid success lies a huge push for a more sustainable energy sector. Sweden already has a cross-party agreement to have all its energy needs met from renewable sources by 2040. To date, renewables’ share of energy consumption in Sweden has risen to as much as 57 percent of the total—in 2015, a year when strong winds and heavy rain made wind and hydroelectric power plants especially productive.

By the end of this year, the country of 10 million should have 3,681 wind turbines producing power. So swift has been the proliferation of Swedish wind farms that the government is facing kickback on their site selection, both for the usual aesthetic reasons but also because they now threaten to encroach on airspace used by the military. Indeed, the expansion push has proved so effective that there are now fears that it might even risk shooting the renewable energy market in the foot.

How has Sweden managed to go so far in an area where other countries continue to struggle, both with will and logistics? It’s certain that high public awareness of environmental issues, a strong economy, and effective governance have all helped. But Sweden’s commitment to renewables is also a response to specifically local conditions, both positive and negative.

For a start, the country’s mountainous, rainy, and sparsely inhabited north made it an obvious place to experiment with that earliest of renewable energy sources, hydroelectric power. With ample suitable rivers crossing an area where dams caused little population displacement, the country has been producing hydroelectric power for over a century.

Sweden still relied on cheap imported oil during most of the 20th century, making the shock of the 1973-4 oil crisis especially sharp. The impact of the crisis on the region isn’t always understood by people whose countries were partly shielded from it by their own oil and gas production. In neighboring and equally stricken Denmark, for example, it led to the wholesale replacement of domestic bathtubs with showers, and tubs are now a rarity in that country’s homes. Faced with spiraling energy prices and a desperate need to make energy savings, Sweden hunted round for locally-produced alternatives to oil.

Sweden still relied on cheap imported oil during most of the 20th century, making the shock of the 1973-4 oil crisis especially sharp.

Following the spirit of the times, it decided nuclear energy was the answer. The Swedish attitude toward nuclear power has been ambivalent. After the 1979 leak at Three Mile Island, Sweden held a national referendum on nuclear energy, with the country voting to phase it out gradually. Since this phase-out did not include plants under construction, nuclear power’s share of the market actually rose after the vote, to as high as 40 percent.

It’s partly a debate about this nuclear reliance that has driven the hunt for more renewables: Three decades after the Chernobyl disaster, Swedish authorities were still picking up radioactive traces in wildlife. The country’s readiness to push for more renewable energy sources is thus not just commitment to a greener world, but a pragmatic reaction to a string of economic and environmental shocks.

These shocks seem to have set Sweden on the path to a renewables boom—but there may still be pitfalls. The example of Denmark shows that gaining a high proportion of your power from renewables can attract energy-hungry businesses looking for a greener location, and that perversely end up increasing the country’s overall carbon footprint. Such has been the attraction of Denmark for communications companies looking for data-center sites that the country will have to rely short-term on fossil fuels to top up its energy needs. Denmark’s reputation as a green energy leader has had the unwanted effect of actually increasing its carbon emissions.
