Green energy for Bulgaria

SENS and LSG finalise over 205 MWp in the heart of Bulgaria 


In order to achieve the EU's climate targets, Bulgaria's vast expanses must switch from fossil fuels to renewable energy such as wind and solar power: 25 percent of energy consumption is to come from renewable sources by 2030. With the completed solar project in Dalgo Pole, in the heart of the country, the SENS LSG joint venture is making a significant contribution to this goal. Over 205 MWp were realised in three construction phases for the Bulgarian Galaxy Investment Group. 

SENS LSG completes two photovoltaic projects

SENS LSG, the joint venture between the Würzburg-based solar service provider Iqony Solar Energy Solutions (SENS) and the Vienna-based LSG Group, has successfully connected two more solar parks to the grid in Dalgo Pole, Bulgaria. With an output of around 91 MWp (megawatt peak) and 50 MWp respectively, the two projects complement an existing 66 MWp plant. The three photovoltaic parks in Dalgo Pole comprise more than 330,000 solar modules and yield over 280,000 megawatt hours (MWh) electricity annually. 


Challenging weather conditions

SENS LSG acted as the EPC (engineering, procurement, construction) service provider and faced high wind loads during the planning and construction phase. This posed specific challenges for the stability of the mounting system and had to be considered when building the substructure of the modules. Some modules used single-axis tracking systems that follow the sun’s path.

Collaboration on an extensive project pipeline

Following the first solar park in the project pipeline in Dalgo Pole built by SENS LSG in 2022, the construction of section B began at the end of 2022. This part of the project is expected to generate approximately 78,000 MWh of green electricity per year. Section C, the largest project, has an annual production of more than 142,000 MWh. In this area of the solar park, approximately 160,000 modules were installed and connected to the grid in less than a year. 

Together, the three photovoltaic systems in Dalgo Pole save around 40,000 tonnes of CO2, which corresponds to the average annual consumption of about 6,000 Bulgarian citizens. Over a 30-year period, this amounts to an estimated total CO2 equivalent of 1,200,000 tonnes.

"We are pleased to have successfully completed three parks of this size. The rapid implementation of these projects underscores the dedication and expertise of our team at SENS LSG and reflects the trust that has placed in us" says Kurt-Stuart Ristl, Head of Project Sales at SENS LSG.

Green energy for Bulgaria

The energy market in Southeastern Europe is still predominantly powered by coal and nuclear power, as is the case in Bulgaria. To meet the European Union's climate change objectives, Bulgaria aims to significantly expand its use of renewable energy, including solar power. By 2030, the country plans to install seven gigawatts (GW) of new solar capacity, with an additional 12 GW planned by 2050. In recent years, the country has increased the share of solar energy in its energy mix from 3.1 per cent in 2021 to 7.7 per cent in 2023.  

"At the moment, there is considerable activity in the Bulgarian and other Eastern European markets. The energy transition here faces numerous challenges and the expansion of renewable energy, especially solar energy, has only been promoted more actively in recent years" says André Kremer, CEO of SENS. "With the completion of two more solar parks, we are reaffirming our commitment to Bulgaria's energy transition and sending an important signal for the future of renewable energy in the country".
