Turkey’s renewables failing to cover power demand growth despite solar boom

Turkey switched in 2024 from a net electricity importer to net exporter, but renewables are still not growing fast enough to meet rising domestic power demand – one of the highest in the world, Ember found. The country has become Europe’s biggest coal power producer and there are plans for more such capacity.

Wind and solar generated 18% of electricity last year or 62 TWh, according to data from Ember’s Türkiye Electricity Review 2025. Together they were higher than domestic coal again, at 47 TWh, after surpassing it for the first time in 2023. But imports account for 61% of coal power production in the country.

Solar power growth spiked 39% in Turkey or by 7.3 TWh and the capacity reached 19.8 GW by the end of 2024. It compares to the global rise of 29% in output.

Photovoltaics had a 7.5% share, after 5.7% one year earlier. The wind power item advanced by only 0.1 percentage point, to 10.7%.

Government’s ambitions for renewables would result in 49% combined solar, wind power share in production

At 5.5%, Turkey had one of the highest increases in power demand last year in the world, mostly because of record meteorological heat pushing up cooling needs. The amount was 18 TWh and the total reached 342 TWh.

The rise in domestic electricity generation totaled 23 TWh and Turkey achieved a switch from a net power importer to net exporter. Nevertheless, wind and solar are still not growing fast enough to meet rising demand, translating to costly imported fossil fuel power generation, the report points out. The situation is similar on a worldwide scale.

The 7.3 TWh increase in solar accounted for 32% of the jump in electricity generation, compared to 40.2% on a global scale. The ambitious renewables targets for 2035 would result in a share of fossil fuels of 20%, and wind and solar at 49% in combination.

“Although demand growth has slowed in recent years, it is still outpacing the rate of new wind and solar additions. Demand increased by 42 TWh in the last five years, compared to 31 TWh of additional wind and solar. The rest of demand is met by imported coal and gas,” said Ufuk Alparslan, the report’s author and the energy think tank’s regional lead for Turkey and the Caucasus.

‍Romania beats Turkey in solar power production share

In the group of 20 countries with the highest electricity demand in Europe, Turkey surpassed Switzerland in solar electricity generation in 2024. On the other hand, it fell one position behind Romania, which is ranked 12th, as it doubled its solar power share to 7.8% in 2024.

The first in the list is Hungary, with 24.9%, followed by Greece (21.5%) and Spain (21.2%).

Adding solar to hydroelectric plants with dams mitigates drought impact

Since 2020, solar power plants can be installed as an auxiliary source in power plants in Turkey, which creates hybrid power plants. Making more use of solar and wind power plants, which have a complementary generation profile to hydroelectricity, will play a key role in ensuring Türkiye’s energy security, the report reads.

Terrestrial and floating solar power plants as secondary sources to existing hydroelectric power plants reduce the risk of a shortfall from hydro in dry years, it added.

Although the amount of incoming water in 2024 was very close to the previous two years, hydroelectric power generation with dams increased by 29%. Total hydropower generation was 75 TWh or 17% more than in 2023 and it was the third-highest result so far.

Turkey is largest coal power producer in Europe

Despite a jump in electricity generation from coal by 3.4% to 122 TWh, its share in electricity mix declined from 36.9% to 35.6%. With coal-fired power generation continuing to decline across Europe, Turkey overtook Germany to become number one. Meanwhile, gas power fell by 4%. It brought the share of fossil fuels in production to 55% — the lowest level since 1993.

There are no coal-fired power plants under construction, but several projects remain. There is a plan to expand the largest facility in the fleet, Afşin Elbistan A (1.36 GW), by two units of an overall 688 MW.

Germany’s coal power output fell 17% to 104 TWh while in Poland, the third in the list, it declined 8% to 91 TWh. As for the share in domestic electricity production, Poland is first, with 53.6%, followed by Czechia (36.5%), Turkey (35.6%), Germany (21.8%), Bulgaria (21.6%), Romania (13%) and Greece, with just 5.7% last year.

As for the Western Balkans, Kosovo* is ranked the highest in the world, now at 92%. Serbia and Bosnia and Herzegovina are fifth and sixth, respectively, both at 63% on a rounded basis.
