What You'll Learn
Nuclear power plants were replaced by wind and solar energy
Sweden's electricity prices are high due to political decisions to shut down nuclear power plants and replace them with wind and solar energy. This has resulted in an increased reliance on expensive fossil fuels during periods of low wind and solar energy production, such as during the winter months. The high electricity prices in Sweden are also influenced by the import of electricity from countries like Germany, which has also phased out nuclear power in favor of wind and solar energy.
Sweden's energy policies have promoted the use of renewable energy sources through initiatives like the Electricity Certificate System, which supports renewable electricity production from wind, solar, geothermal, wave power, biofuels, and small-scale hydroelectric plants. While this transition to renewable energy has environmental benefits, it also comes with economic costs. The country's electricity generation sector has undergone a significant transformation since the introduction of nuclear power, with consumption more than doubling.
The share of renewable energy in Sweden has been growing, and the country reached its 2020 target of 50% renewable energy in 2012. The power sector aims for 100% renewable electricity production by 2040. Sweden has a rich supply of moving water and biomass, with hydropower and bioenergy as the top renewable sources. However, wind power has been the fastest-growing source of renewable energy in Sweden and worldwide, and it is expected to play a significant role in the country's energy mix in the future.
According to a leading think tank, building more onshore wind parks is the cheapest way for Sweden to meet its expected rise in electricity demand and achieve its goal of net-zero emissions by 2045, rather than increasing the number of nuclear power plants. Additionally, energy flexibility measures, such as running industrial processes during off-peak hours, can help manage the need for "base" power when there is low wind energy production.
While nuclear power plants were once a significant source of electricity in Sweden, the country has been transitioning towards wind and solar energy to meet its climate goals and increase the use of renewable energy sources. This shift has had economic and environmental impacts, and Sweden continues to face the challenge of managing electricity costs and supply.

Wind and solar energy production is low in winter
Sweden has been working towards increasing its renewable energy sources in recent years. In 2012, the country reached its 2020 target of 50% renewable energy usage. The country's energy plan is to have 65% of its energy produced by renewables by 2030 and 100% by 2040. The share of renewable energy used in Sweden continues to grow, with 98% of electricity generation coming from renewables and nuclear in 2023.
Sweden's renewable energy sources include hydropower, bioenergy, wind, solar, biomass, and geothermal energy. Hydropower and bioenergy are the top renewable sources in the country, with hydropower being used mostly for electricity production and bioenergy for heating. Wind power has also grown significantly in Sweden and today accounts for almost 20% of the country's electricity. In 2000, Swedish wind production totalled 0.5 TWh, and in 2022, it was just over 33 TWh. There are now more than 4,700 wind turbines in Sweden.
However, wind and solar energy production is low in winter. In a simulation of a mid/near-future scenario for Sweden, neither solar nor wind power provided any significant amounts of power during the winter. This is because electricity production from wind and solar is on the verge of non-existent when it is coldest in Sweden. For example, solar energy produced 0% of its maximum capacity throughout February 2019, and wind power production was lower than 10% of its maximum capacity on several occasions during the same month.
The low wind and solar energy production in winter means that Sweden relies on other energy sources during this time, such as hydro, nuclear, and thermal power. The availability of these alternative energy sources affects the cost of electricity in Sweden. For instance, the premature closure of nuclear power plants in Sweden and neighbouring countries has led to a greater reliance on electricity from wind power, which is more expensive to produce. As a result, electricity prices in Sweden can be high, especially during the winter when wind and solar energy production is low.

Sweden imports electricity from Germany
Electricity prices in Sweden have been exceptionally high, with the average price of electricity in 2022 being 1.45 kronor (0.13 US dollars) per kilowatt-hour (kWh). This was 128% higher than in 2021. During the high-demand hours in the morning and late afternoon, hourly prices in southern Sweden hit a peak of 7.25 kronor per kilowatt-hour.
There are several reasons for these high electricity prices in Sweden. Firstly, Sweden has shut down several well-functioning nuclear power plants and is now relying on wind and solar power, which are unreliable due to weather conditions. In February 2019, solar energy produced 0% of its maximum capacity, while wind power production was lower than 10% of its maximum capacity on several occasions. This has resulted in Sweden "'importing'" high electricity prices from other countries, as they allow Swedish electricity producers to sell their electricity at very high prices, leading to large profits that Swedish consumers have to bear.
Germany is one of the countries that Sweden imports electricity from. Germany has also phased out most of its nuclear power plants and replaced them with wind and solar farms, which need to be supplemented with electricity production from expensive fossil fuels. This results in Germany exporting its high electricity prices to neighbouring countries, including Sweden.
The interconnection between Sweden and Germany allows for the trade of electricity between the two countries. Sweden's electricity sector is part of the Synchronous grid of Northern Europe, which includes Germany. This interconnection enables the import and export of electricity between the two countries, balancing out supply and demand across regions.
In summary, Sweden imports electricity from Germany due to the phase-out of nuclear power plants in both countries and the reliance on wind and solar power, which can be unpredictable. The import of electricity from Germany contributes to the high electricity prices in Sweden, as Germany's electricity prices are also high due to their energy sources and production methods.

Sanctions on Russian gas have impacted energy prices
Since Russia's invasion of Ukraine, many countries have imposed sanctions on Russian energy imports to curtail Moscow's revenues and hinder its war efforts. Europe is a major importer of Russian energy, and EU nations have ended imports of Russian oil brought in by sea, with a ban on refined oil products also in place. The UK has also stopped importing Russian oil, and the US has said it will stop importing Russian oil and gas.
The sanctions have impacted the Russian economy, as the energy sector is a key source of revenue. Moscow is losing out on significant sums of money from fossil fuel exports due to these measures. Russia has also cut gas supplies to Europe, impacting energy flow and causing prices to soar. The price of oil has risen to over $130 per barrel, and natural gas prices have also hit record highs.
While the sanctions have had a significant impact, the Russian energy industry is too strong and resilient to collapse under their weight. However, the industry is suffering enormous difficulties, and over time, this will likely result in further losses of investment, output, efficiency, and revenue.
Sweden, in particular, has faced soaring electricity prices due to the sanctions on Russian gas. While natural gas accounts for only around 3% of Sweden's energy consumption, the country has not managed to replace the gas it previously imported from Russia. In addition, Sweden's decision to shut down several nuclear power plants and replace them with wind turbines has resulted in higher electricity prices, as wind power is unreliable and cannot meet demand during the coldest months. Sweden's electricity prices are also influenced by those of its neighbouring countries, particularly Germany, which has also phased out nuclear power in favour of wind and solar energy, resulting in the need to supplement with expensive fossil fuels.
Overall, the sanctions on Russian gas have contributed to rising energy prices, with Sweden being particularly affected due to its reliance on imported energy and the premature closure of its nuclear power plants.

Weather impacts electricity production and usage
The weather has a significant impact on electricity production and usage. Weather patterns play a crucial role in determining the cost of electricity, especially in the context of renewable energy sources such as wind, solar, and hydropower. For example, abundant wind and rain boost electricity production from wind turbines, while droughts and a lack of wind reduce production from these sources. Similarly, solar energy production relies on sunlight availability, and extreme cold or cloud cover can render it ineffective.
In Sweden, the impact of weather on electricity production and usage is notable. Sweden has made a political decision to replace nuclear power plants with wind turbines, which has resulted in a reliance on wind power for electricity production. As a result, during periods of low wind or extremely cold temperatures, Sweden may experience reduced electricity production from wind turbines and a need to import electricity from neighbouring countries, leading to higher electricity prices.
Additionally, extreme weather conditions can disrupt the electricity supply chain and infrastructure. For instance, freezing temperatures can temporarily put wind farms and gas lines out of commission, leading to reduced electricity production and transmission. Wildfires, hurricanes, and storms can also damage electrical distribution lines and infrastructure, causing power outages and fuel shortages. These disruptions can have significant economic consequences, affecting both households and industries that rely on a stable supply of electricity.
The vulnerability of the energy system to weather conditions is expected to increase with the continued electrification of various sectors, such as heating and cooling, which is the largest source of energy end use globally. As demand for cooling increases, more electricity must be produced, potentially leading to increased emissions and contributing to climate change. This, in turn, can further impact the weather, creating a cycle that affects the reliability and affordability of energy.
To mitigate the impact of weather on electricity production and usage, several strategies can be employed. These include expanding access to diverse renewable energy sources, such as solar and wind power, modernizing infrastructure to increase resilience, and implementing energy-saving measures to reduce overall demand. By diversifying energy sources and improving infrastructure, the reliability and affordability of electricity can be enhanced, reducing the vulnerability of the energy system to weather-related disruptions.

Frequently asked questions
Electricity prices in Sweden are high due to a combination of political decisions, weather dependence, and the subsequent need to import electricity from neighboring countries. Shutting down nuclear power plants and relying on wind and solar energy has led to insufficient electricity production during periods of low wind and sun, forcing Sweden to import electricity at higher prices.
Weather conditions significantly affect electricity production and consumption in Sweden. Abundant wind and rain boost wind and hydropower production, while drought and calm conditions reduce it. In winter, electricity demand increases, and production from wind and solar sources decreases, leading to higher prices.
When Sweden imports electricity during periods of high demand and low production, Swedish electricity producers are allowed to sell their electricity at very high prices, resulting in soaring electricity bills for Swedish households and businesses.
To cushion the impact of high electricity prices, the Swedish government has provided financial support in the past. Additionally, individuals can explore alternative energy sources, such as solar panels with sand batteries, to store energy during the summer for use in winter when prices are typically higher.
