Solar energy firm Simtel plans to construct a 60 MW solar park in Tulcea County, for energy provider Verbund.
In August 2025, Romanian engineering and technology group Simtel signed a significant contract with Verbund Wind Power Romania, a subsidiary of Austria's Verbund group. The contract, worth approximately EUR 19.1 million (excluding VAT), involves the design, construction, and commissioning of a 60 MWp photovoltaic (solar) park in Casimcea, Tulcea County, Northern Dobruja.
The solar park will be a turnkey project, designed to complement and hybridize the existing CAS South 2 wind farm operated by Verbund in the same area. This hybridization is one of the most significant hybrid renewable projects in Romania and represents a key milestone in Romania’s energy transition.
The new solar park will be located in Casimcea, Tulcea County, and is part of an EPC (Engineering, Procurement, Construction) contract awarded to Simtel. The contract includes a 15-month construction and commissioning period, followed by a 36-month performance guarantee period.
Simtel currently provides operation and maintenance services for solar parks with a combined installed capacity exceeding 450 MWp. The Casimcea project will be one of the 412 solar plants under Simtel's maintenance. With over 5,000 interventions annually on the solar parks they manage, Simtel's maintenance activities are extensive.
Verbund has been operating the 226 MW wind farm in Casimcea since 2012. The hybrid system leverages Northern Dobruja’s complementary wind and solar resources to reduce curtailment and enhance grid stability and revenues. This expansion and diversification in Romania's renewables by Verbund will enhance their existing wind portfolio with solar capacity, creating a hybrid renewable energy site.
Simtel's experience in the solar industry spans across multiple industries. In the past five years, they have designed and commissioned photovoltaic installations totaling over 500 MWp across multiple industries. Verbund, Austria's largest energy producer, will benefit from Simtel's expertise in this project.
This project reflects Verbund’s expansion and diversification in Romania's renewables, enhancing the existing wind portfolio with solar capacity to create a hybrid renewable energy site. The hybrid system is expected to be operational by late 2026, furthering Romania's commitment to renewable energy and grid stability.
