Greek companies expand to Bulgaria with solar power investments

Greece’s government-controlled power utility PPC and Masdar’s subsidiary Terna Energy are separately building two photovoltaic plants in Bulgaria, worth an estimated EUR 190 million in total.

The biggest two renewable energy companies in Greece have taken over one major project each in neighboring Bulgaria, where domestic investors dominated the photovoltaics market until recently. Soon after government-controlled Public Power Corp. (PPC) said it began building a 165 MW solar power plant with batteries, Capital reported that Terna Energy plans to complete a 130 MW project by the end of next year.

The segment appears saturated, given the lack of energy storage capacities in Bulgaria to balance high PV output at times of abundant sunshine. Permits that the Sustainable Energy Development Agency (SEDA) issued show 4 GW in overall installed solar power capacity. Nevertheless, Executive Director of Electricity System Operator (ESO) Angelin Tsachev estimated there is as much as 5 GW, the media outlet noted.

In its annual statistics update, the International Renewable Energy Agency (IRENA) said Bulgaria hosted 3.9 GW of PV capacity at the end of 2024.

Terna Energy bought out initial developer one year ago

Terna Energy became a subsidiary of Abu Dhabi Future Energy Co. (Masdar) last year. The Greek company entered the ownership of the project firm Bio PD Solar Energy for the 130 MW facility three years ago with a 25% stake.

In mid-2024, Terna Energy Overseas Ltd., registered in Cyprus, became the sole owner. It invested some EUR 25 million and bought out Helios Construction Project. According to the article, the previous parent company is associated with businessman Ahmed Dogan. He was the founder and long-time leader of the Movement for Rights and Freedoms party, representing Muslim minorities.

Both projects are on municipal land

The project spanning more than 200 hectares was initially planned at 180 MW. The lot is on municipal land in Kameno in eastern Bulgaria.

According to the news website, the investment amounts to EUR 92 million. The location near the village of Vratitsa isn’t subject to an environmental impact assessment study except for the intended construction of a 33/110 kV substation.

Terna Energy said its former affiliate Terna, part of the GEK Terna conglomerate, is building the solar power plant in Burgas province.

New hybrid power plant in Bulgaria is part of PPC’s regional expansion

PPC is building its PV plant in the Chirpan municipality in Stara Zagora province. Having included a battery energy storage system in the project, and given the power links with its assets in Romania and Greece, the company is counting on a strategic advantage in the market with the new hybrid facility. PPC is pursuing major expansion in the region, including Italy.

The investment is valued at EUR 97 million, of which the energy storage segment accounts for EUR 10.2 million to EUR 12.8 million, the article adds.

The Colosseum site consists of 11 municipal properties formerly designated as agricultural land, on 200 hectares altogether. PPC bought the project from Enery. The company is headquartered in Austria and active in the renewables sector in Romania as well.
