For the first time in more than a quarter century, renewable sources supplied nearly three-quarters of Turkey’s electricity generation during the month of May, according to the latest grid data. Renewable energy accounted for 72.3 percent of the country’s power output for that month, surpassing the previous high-water mark set in the late 1990s.
The milestone represents the largest share recorded since modern record-keeping began 26 years ago, sources familiar with the figures said. The May figure marks a sharp acceleration from recent years, reflecting a sustained transformation in Turkey’s power sector. Over the past decade, hydropower, wind, and solar have steadily displaced thermal generation, with coal’s share of the mix falling during the same period.
Analysts tracking the country’s energy transition point to a combination of new hydro capacity coming online and seasonal conditions that boosted river flows as key drivers of the May record. In addition, wind and solar farms have expanded rapidly, with installed capacity rising each year.
Record Renewable Share Driven by Hydro, Wind, and Solar
The government has set targets for renewable deployment as part of its long-term energy strategy, though officials have not commented directly on the May milestone. The record comes as Turkey continues to import natural gas and coal to operate power plants that run when renewable sources are not available. Grid operators have managed to integrate higher shares of variable generation without major disruptions, according to filings reviewed by this reporter.
Renewable energy is power derived from natural sources that replenish on a human timescale, such as sunlight, wind, and flowing water. Its use stretches back centuries, with early hydropower driving mills and windmills harnessed for mechanical work long before the modern era.
The late 19th and early 20th centuries saw the first large-scale hydroelectric plants, marking the beginning of renewables as a significant part of electricity supply. Over the past few decades, solar and wind technologies have advanced from niche applications to major contributors to the global power mix. Costs for these technologies have fallen sharply, making them increasingly competitive with conventional fossil fuels in many regions. This shift has been driven by a combination of technological improvements, supportive policies, and growing concern over the environmental impacts of coal, oil, and natural gas.
The push for renewable energy is closely tied to efforts to reduce greenhouse gas emissions and limit climate change. Unlike fossil fuels, most renewable sources produce little to no direct emissions during operation, offering a cleaner alternative for power generation.
They also reduce dependence on finite resources and can enhance energy security by diversifying supply.
Grid Integration and Future Challenges
Today, the expansion of renewables represents a central pillar of energy strategies worldwide, as countries seek to balance economic growth with environmental sustainability. The ability to integrate higher shares of variable sources like wind and solar into national grids has become a key test for modern energy systems. In Turkey’s case, the record May share demonstrates that grid operators have so far managed to handle increased penetration without major disruptions, according to filings reviewed by this reporter.
What to watch next is whether the summer months, when electricity demand peaks for air conditioning, will test the grid’s ability to maintain such a high renewable penetration. The June and July figures, due in the coming weeks, will show whether May was an outlier or the start of a new trend.
Analysts will be closely monitoring those results for signs of how the system performs under seasonal stress. The background of this development is rooted in a decades-long evolution of renewable technology and policy. From early watermills and windmills to modern solar panels and wind turbines, the harnessing of natural forces for power has advanced enormously. The sharp decline in costs has enabled countries like Turkey to scale up renewable capacity rapidly, reducing reliance on imported fossil fuels while addressing environmental concerns.
The May record underscores the accelerating pace of this transition, even as challenges of grid reliability and seasonal variation remain.
