Polat Enerji completes largest wind-BESS hybrid power plant in Turkey

Polat Holding’s joint venture with İş Enerji has received the license for the 12.8 MW battery energy storage system (BESS) integrated with its Ege wind power plant of 15.2 MW in western Turkey. It is the largest hybrid power plant of its kind in the country.

In cooperation with SolarToday Türkiye and iNOVAT, Polat Enerji reached another milestone in combining renewable energy plants with battery storage. The Ministry of Energy and Natural Resources of Turkey has issued an approval for its BESS with 12.8 MW in operating power and a capacity of 15.2 MWh.

The facility is integrated with the company’s Ege wind power plant. They are located in the Kemalpaşa district of Izmir province in the country’s west. It is Turkey’s first DRES, an acronym for a licensed wind-storage system, of 10 MWh or more. The companies pointed out it is also the first hybrid power project of its kind to receive incentives.

Polat Enerji’s BESS consists of four 3.8 MWh units manufactured by Contemporary Amperex Technology Co. Ltd (CATL) from China. In the second phase, the capacity will reach 28.2 MWh, according to the update.

In the second phase, BESS capacity will reach 28.2 MWh

Electricity from wind turbines will be stored and delivered to the grid to cover production imbalances and stabilize the system. The companies signed the agreement about the battery project in January.

Ege was built in 2015. The wind park consists of eight turbines, of which the last two were connected almost two years ago. It has 15.2 MW in nameplate capacity and a 13 MW connection.

Earlier this month, Polat Enerji won a 160 MW project at a wind power auction under Turkey’s YEKA support mechanism. The company is a joint venture of Polat Holding and İş Enerji Yatirimlari, each holding 50%. The latter is a subsidiary of Türkiye İş Bankası, the largest private sector bank in Turkey.

The ministry said today that the country’s wind power capacity reached 14.5 GW in November, out of 121.8 GW in total. There was 24.7 GW of solar power in operation.

Turkey awards 1.15 GW in wind power auctions – all at just EUR 35 per MWh

The six winners from the latest round of wind power auctions under the YEKA state support mechanism in Turkey will have at least EUR 35 per MWh guaranteed from the sale of electricity in the first six years. It was the floor price in the bidding. After it was reached for each zone, the remaining participants had to compete by offering to pay for the right to sign the contract.

Delays and the lack of money for the construction of high-voltage, transmission lines is one of the main hurdles slowing the uptake of wind and solar power. Turkey’s approach has turned out to be successful, as it allows investors to compete to pay one-off fees for available predetermined projects in auctions. At the same time, the beneficiaries get guaranteed prices for the future sales of their electricity.

The country has earned EUR 530 million overall this year from two rounds for solar and two for wind power, Minister of Energy and Natural Resources Alparslan Bayraktar said. It includes EUR 208 million just from the latest bidding under the Renewable Energy Zones (REZ) state support mechanism, he claimed. It is better known by its Turkish acronym YEKA.

The winners are getting grid connections for 49 years

The ministry awarded zones for six projects for 1.15 GW in total connection capacity. The winners are getting grid connections for 49 years, a minimum price during the six-year open market sale period and power purchase agreements (PPAs) at the same level for another 20 years.

Entire capacity allocated at floor price

In the bidding in the REZ WPP 2025 (YEKA RES 2025) round, the ceiling price was EUR 55 per MWh. With 75 applications altogether, 30 companies participated – between six and 20 per zone.

In all cases, the bottom price of EUR 35 per MWh was reached, so the remaining bidders were switched to the second phase. The YEKA auctions are broadcast live.

The winners need to pay between EUR 56,000 per MW and a stunning EUR 312,000 per MW of capacity, or from EUR 23.8 million to EUR 34.3 million for each zone. Combined, the contribution fees amount to EUR 173 million, or some EUR 470 million for all auctions held this year.

Bayraktar estimated total investments in projects involved in the last wind power round at USD 1.1 billion.

Eksim, Polat among winners

The Kütahya zone of 120 MW went to İçdaş Elektrik Enerjisi, for EUR 222,000 per MW. Stone Enerji snatched the Aydın-Denizli project of 140 MW with a winning bid of EUR 170,000 per MW. The firm was a winner at the recent solar power auctions as well.

For the Sivas area, the largest of all (500 MW), Kanat Rüzgar Enerji will be required to pay EUR 56,000 per MW, which is the lowest level.

Three zones are in Balıkesir province. Eksim Energy (Enerji) committed the most of all winners, EUR 312,000 per MW, for the Balıkesir-3 project. It is for 110 MW. Balıkesir-2, of 120 MW, was won by Balıkesir Elektrik. It offered a contribution fee of EUR 218,000 per MW.

The Balıkesir-1 area is for 160 MW in connection capacity. Polat Enerji’s subsidiary Soma Enerji was the best bidder, with EUR 212,000 per MW.

Turkey hosts wind power plants of more than 14 GW combined, of more than 121 GW in total electricity capacity.

Solar park of 46.6 MW integrated with Turkey’s fifth-largest wind farm

The newest hybrid power plant in Turkey consists of wind turbines of 168 MW and a solar park with 46.6 MW in capacity. Polat Enerji is about to expand the Geycek facility with a 10 MW battery energy storage system.

Hybrid power plants are all the rage in Turkey and the ones coming online are bigger and bigger. The latest addition to the fleet is Polat Enerji’s Geycek facility. It is the country’s fifth-largest wind park, and now it also features a 46.6 MW photovoltaic unit. It is classified as an auxiliary source in domestic law.

That’s not all. The company, which has been pioneering the technology in Turkey, contracted a battery energy storage system (BESS) two months ago. T Dinamik Enerji’s subsidiary Tegnatia is tasked with installing a Sungrow unit with 10 MW in operating power and 13.4 MWh in capacity.

Polat Enerji is turning Geycek into Turkey’s first utility-scale hybrid of wind, solar power and BESS

It would be the country’s first wind-solar-battery hybrid on a utility scale. Polat Enerji said it would be commissioned “in the near future.”

Geycek is in Mucur district in the province of Kırşehir, southeast of Ankara. The wind park has 168 MW.

The contractor for the solar power segment was SPI (Schmid Pekintaş Investments) Energy Solutions. The Schmid Pekintaş joint venture supplied the PV panels.

Polat also operates Turkey’s largest wind power plant – Soma. It recently expanded it by 8.4 MW in nameplate capacity, or 8 MW effectively, reaching 328.9 MW and 304.1 MW, respectively. It is the first such facility in the country with over 300 MW on the grid.

The Soma wind park includes a small BESS unit – 4 MW of capability and a one-hour duration, translating to 4 MWh.

Polat Enerji is a joint venture of Polat Holding and İş Enerji Yatirimlari, each holding 50%. The latter is a subsidiary of Türkiye İş Bankası, the largest private sector bank in Turkey.
