Maguire: The dawn of Turkey's nuclear age is crucial to its clean energy plans

The world's biggest nuclear power pipeline could help Europe, the top coal-fired polluter in Europe, boost its power output and reduce future emissions.

Global Energy Monitor (GEM) reports that Turkey is developing 4,800 megawatts of nuclear power generation capacity, which is the world's third largest pipeline. There are currently no nuclear power plants in operation.

Once fully operational, the plant will generate 10% of Turkey's electrical needs.

The Russia-built facility, on the South Coast, has experienced numerous delays and costs overruns, raising questions about its likelihood of starting up in time for the four planned stages.

The country is experiencing a rapid increase in demand for electricity, and any delay in nuclear operations could lead to an acceleration of coal-fired energy production.

NUCLEAR PHASES AND SANCTIONS

The first Akkuyu unit, built by the Russian State Atomic Energy Corporation Rosatom is expected to be online in this year. It has a nominal capacity of 1,200 MW.

According to Akkuyu, the equipment start-up, testing, and pumping station of the pressurized Water Reactor's cooling system and pumping stations began in early January. The site also passed an independent safety examination in January.

The remaining three 1,200 MW power units will be added annually in 2026-2027-2028 at an estimated cost of $20 billion.

The remaining reactors can be completed on schedule, given the state of construction of the site.

Rosatom reported that it was having difficulty obtaining certain parts due to the sanctions imposed on several Russian entities after Russia invaded Ukraine in 2022.

The new administration of U.S. president Donald Trump could face further delays and difficulties in sourcing after the imposition by Trump of new sanctions against Russia.

COAL CRUTCH

While Turkey's first nuke plant is being finished, its power companies continue to run the fleet of coal-fired units, which provided around 35% the electricity in Turkey last year.

According to the energy think tank Ember's report, its coal plants will generate a record of 121 terawatt-hours (TWh) in 2024. They will also emit a record of 114 million tonnes of carbon dioxide. This is the highest amount of CO2 emissions in Europe.

According to Kpler, a ship tracking firm, Turkey imported around 26.5 millions metric tons (or roughly 55 million metric tonnes) of thermal coal in 2024. This was the eighth highest national import total worldwide.

In Turkey, hydropower plants produced the second most electricity last year. This was around 75 TWh. Gas plants generated about 63 TWh.

The volatility of gas and precipitation prices in recent years has stifled the growth in gas and hydro-fired power generation, forcing Turkey's energy firms to remain dependent on coal as the main source of power.

CAPACITY CLUSTER

According to Turkey's pipeline of power capacity, there is no "Plan B" in place for the Akkuyu Plant in the event that it starts late.

According to GEM, the energy data organization, there is currently no new coal-fired power capacity under construction. Only 890 MW worth of gas-fired power is being built.

Around 20 MW geothermal power, around 160 MW hydropower, and 250 MW solar capacity are also being built.

The new additions to capacity will increase the clean energy share in Turkey's mix of capacity to 49.5%. This is up from the current 47% and reduce fossil fuels to 50.5%.

The total capacity of non-nuclear power plants currently being constructed in Turkey is less that 30% of planned nuclear capacity.

The lack of alternative capacity development is a sign that the country has confidence in bringing up the nuclear plants as soon as possible.

The limited capacity to increase power production in Turkey without the new fleet of nuclear reactors also means that the power companies will be reliant on the fossil fuel plants they currently have until Turkey finally enters the nuclear age.
